ACTION: UPON MOTION BY COMMITTEE MEMBER BAER, SECONDED BY COMMITTEE MEMBER KINCAID, the Cultural Heritage Committee approved the following recommended goals to the City Council for their review during the goal-setting process beginning in January 2017: Cultural Heritage Committee Goals FY 2017-2019 The Cultural Heritage Committee requests the City Council consider the following goals: Historic Preservation and Economic Development Recent statistical research shows that urban neighborhoods comprising smaller buildings of diverse age provide: • greater density of population, businesses, and creative economy jobs per commercial square foot Cultural Heritage Committee Minutes DRAFT of November 28, 2016 Page 4 • a significantly higher proportion of new, local, and women- and minority-owned businesses • a lower median age and greater diversity of age and race • more nightlife, walkability, and transit friendliness.1 The Cultural Heritage Committee recommends city government invest in the following projects to harness our Historic Preservation Program in support of sustainable economic development: 1. Update the 35-year-old Historic Resource Inventory The California Office of Historic Preservation recommends updating historic resource inventories every five years. San Luis Obispo has not done a global revision in thirty-five years, making development decisions difficult and unpredictable. The CLG grant-funded City of San Luis Obispo Citywide Historic Context Statement of 2014 logically leads to a historic resource survey. 2. Develop a self-funding program for City-owned historic sites and buildings. These range from the National Register Carnegie Library and Jack House and Garden to City Hall and numerous adobes. 3. Re-evaluate new and existing historic district boundaries. New districts may include a West End Historic District encompassing the area of Higuera and Marsh Streets southwest of the Downtown Historic District and an Anholm Addition Historic District surrounding Broad Street north of US Route 101. 1 Preservation Green Lab, Impresa, Basemap, Gehl Studio, State of Place, Older, Smaller, Better: Measuring How the Character of Buildings and Blocks Influences Urban Vitality , National Trust for Historic Preservation, 2014. on the following 6:0:1 vote: AYES: Baer, Kincaid, Larrabee, Walthert, Brajkovich, Hill NOES: None ABSENT: Papp COMMENT AND DISCUSSION 1.

SITE DATA Applicant Representative General Plan and Zoning Site Area Environmental Status Coastal Community Builders Brian Schwartz and Marshall Ochylski Specific Plan Area (various land use designations including— residential, commercial, office, open space and agriculture consistent with the Land Use Element) 131.3 acres A Draft EIR is now under public review. The public review period has been extended to January 30, 2017. 2.0 SUMMARY Coastal Community Builders has proposed a project that includes several entitlements for the development of approximately 70 acres of the 131.3-acre property. The project would include a mixture of residential and non-residential uses, as well as the preservation of approximately 53 acres to remain in agricultural use and open space. The project site is currently outside the City, but within its Sphere of Influence, and would require annexation for development. The project as proposed is envisioned to implement the policies for development of the site as articulated in the 2014 Land Use and Circulation Elements (LUCE) update, and be consistent with the broad development parameters set forth in the LUCE for this designated specific plan location. Meeting Date: January 23, 2017 Item Number: 1 CHC 1-1 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 2 The Draft EIR includes evaluation of Cultural Resources (Attachment 1) affected by the project proposal including the Dalidio Ranch complex of structures. The Draft EIR has been referred to the Cultural Heritage Committee in order to receive focused comments on Cultural Resources analysis which can be incorporated into the Final EIR for responses to comments and included with the discussion when the Planning Commission and City Council consider certification of the Final EIR and project approval. Staff has attached relevant sections of the EIR including the Cultural Resources evaluation section and the Cultural Resources Survey and Evaluation (Attachments 1 & 2). The complete EIR can be found on the City website here: http://www.slocity.org/government/department-directory/community-development/documents- online/environmental-review-documents/-folder-1881 3.0 CHC PURVIEW The CHC’s role is to review the Cultural Resources section of the Draft EIR (Attachment 1) and provide any feedback regarding the adequacy of the cultural resources evaluation and additional needed information or modifications or issues which should be addressed in mitigation measures. Staff will be available to clarify information contained in the Draft EIR, or to respond to straightforward questions, but comments related to technical analysis are more appropriately responded to in the Final EIR, once staff and the EIR consultant are able to accurately perform any needed technical review or evaluation. Response in the Final EIR also provides full disclosure for all interested parties instead of the information only being provided to members of the public in attendance at the meeting. All comments received in this CHC review will be responded to and included in the Final EIR. The public comment period for the EIR closes on January 30, 2017. The Draft EIR was introduced at a Planning Commission workshop on January 11, 2017, and the Planning Commission will be completing the Draft EIR workshop and taking additional public comment at the Planning Commission meeting of January 25, 2017. 4.0 SITE INFORMATION The site is comprised of approximately 131 contiguous acres in unincorporated San Luis Obispo County, surrounded by areas within the City of San Luis Obispo, and within the City’s Sphere of Influence, generally bounded by Madonna Road, Dalidio Drive and U.S. Highway 101. Dominant features at the site are the predominantly flat landform seasonally planted with row crops, an existing stand of eucalyptus trees in the southwest portion of the site, and the Dalidio farm home in the northwest portion of the site.

The project is intended to be consistent with policy direction for the area included in the General Plan, specifically Land Use Element Policy 8.1.4, which identifies the San Luis Ranch area as a Special Focus Area (SP-2), subject to policies for the development of a specific plan and certain broad development parameters and principles. The relevant portion of this policy that relates to cultural resources is included below: Policy 8.1.4: SP-2, San Luis Ranch (Dalidio) Specific Plan Area. The project site should be developed as a mixed use project that maintains the agricultural heritage of the site, provides a commercial/ office transition to the existing commercial center to the north, and provides a diverse housing experience. Protection of the adjacent creek and a well- planned integration into the existing circulation system will be required. The specific plan for this area should consider and address the following land use and design issues: n. Historic evaluation of the existing farm house and associated structures shall be included. The Conservation and Open Space Element of the General Plan addresses historic resources within the City. New development is evaluated for consistency with the following adopted goals and policies relating to historic resources: Goal 3.2. Historic and Architectural Resources. The City will expand community CHC 1-3 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 4 understanding, appreciation, and support for historic and architectural resource preservation to ensure long-term protection of cultural resources. Policy 3.3.1. Historic Preservation. Significant historic and architectural resources should be identified, preserved, and rehabilitated. Policy 3.3.2. Demolitions. Historically or architecturally significant buildings shall not be demolished or substantially changed in outward appearance, unless doing so is necessary to remove a threat to health and safety and other means to eliminate or reduce the threat to acceptable levels are infeasible. Policy 3.3.3. Historical Documentation. Buildings and other cultural features that are not historically significant but which have historical or architectural value should be preserved or relocated where feasible. Where preservation or relocation is not feasible, the resources shall be documented and the information retained in a secure but publicly accessible location. An acknowledgement of the resources should be incorporated within the site through historic signage and the reuse or display of historic material and artifacts. Goal 3.4. Historic and Architectural Resources. The City will expand community understanding, appreciation, and support for archaeological resource preservation. Policy 3.6.3. Construction within Historic Districts. The Cultural Heritage Committee and Architectural Review Commission will provide specific guidance on the construction of new buildings within historic districts. 6.0 PROJECT SUMMARY AND HISTORICAL CONTEXT 6.1 Project Description Summary The project is a Specific Plan, General Plan Amendment, and related actions that would allow for the development of the San Luis Ranch (formerly referred to as Dalidio) area as identified in the City’s General Plan. The project includes a mix of residential, commercial, and office uses while preserving nearly half of the site as open space and agriculture on a 131.3-acre property. The intent is for the project to be consistent with the development parameters described in the City’s recently updated Land Use Element, which envisions up to 500 residential units, 200,000 square feet of commercial uses, 150,000 square feet of office, 200 hotel rooms, at least 5.8 acres of parks, with a goal of preserving 50% of the site in agriculture and open space. CHC 1-4 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 5 6.2 Historical Context and Onsite Resources The project site is comprised of several lots that were subdivided in 1875, when the Laguna Rancho was sold off into plots for small family farms. Each property consisted of a farm complex with a home. A horse race track originally located in the vicinity of Madonna Plaza was moved onto the project site. The track facility included stables and a spectators’ barn/viewing stand that provided seating for town people to watch the races. A small house was originally connected to the spectator barn/viewing stand in its original location, but was detached and moved it to its present location on the project site. The stables that had been associated with the race track were removed from the site and the spectators’ barn/viewing stand was further altered by the addition of a dairy, stables and conversion of the spectator seating area to hay storage. In approximately 1921 ownership of the project site changed and the site was converted to farmed crops such as onions, artichokes, and garbanzo beans, as well as flowers for seed (Bertrando 1999a1; Stewart 19992). The agricultural business on the project site was known as Zapata Farms starting in the early 1980’s. The property changed ownership again in 2014 and it has recently been known as San Luis Ranch. The Dalidio/San Luis Ranch Complex (P-40-041000) has been identified as a historic resource. The complex is located on the northwest portion of the project site, near Madonna Road. Singer and Atwood (1988)3 conducted a cultural resources survey of the project site in 1988, and identified “two wood frame structures, a large, two-story house and a barn” as having potential historical significance. Betsy Bertrando recorded and evaluated the Complex in 1999 and identified eight historic built environment resources including the Dalidio home, a bungalow, a small shed/bunkhouse, a garage, a water tower, a barn, a large equipment storage building, and the race track viewing stand. The Dalidio Complex presently includes nine structures, described in detail below. The water tower that was recorded on the project site in the 1999 Bertrando analysis was not observed during the investigation for the current project. As shown in Figure 1, below, the project site currently contains a grouping of nine structures at the northwest end of the property, collectively known as the Dalidio Ranch Complex. The Dalidio Ranch Complex includes three single-family residences, a garage/shed, a smaller shed, the main barn, a large equipment storage building, a warehouse, and the former spectators’ barn/viewing stand, which was converted to farm use (Figures 4.5-2a through 4.5-2e in the Cultural Resources Evaluation, Attachment 2). 1 Bertrando and Bertrando Research Consultants, Historic Resources Inventory and Evaluation for the San Luis Marketplace Annexation, 1999 2 “The Dalidios”, SLO Magazine, September 14, 1999 3 Singer, C. and Atwood, J.

Existing Onsite Buildings – Dalidio Ranch Complex CHC 1-6 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 7 The following is a summarized description of each of the structures within the Dalidio Complex:  Main Residence (Residence #1). The main residence is a single-family residence estimated to have been built ca. 1910. It is irregular in plan and built in the C raftsman style. This structure features a high pitched, front-gabled roof, with overhanging eaves and exposed rafter tails. The roof is clad in composition shingles. There is a shed dormer on the northeast side of the roof. On the southwest side a hipped roof extension covers the wrap-around porch and a cantilevered box bay window. The home is clad with shiplap and clapboard siding as well as shingles on the gable face.  Residence #2. This single family home is estimated to have been built ca. 1900-1910. It is rectangular in plan and appears to have a small addition on the east elevation as well as a shed extension on the south. The eastern addition includes a chimney. Both the main portion of the home and the addition feature medium pitched front-gabled roofs and an open eave overhang with fascia boards. The roof is clad with composite shingles. The shed extension features a nearly flat roof partially clad with corrugated panels.  Residence #3. This single family home is estimated to have been built in the 1960s. It is roughly square in plan, clad with reverse board and batten and has a side-gabled roof clad with composition shingles. There are horizontally slatted vents under the gable peaks. The home features aluminum sliding windows surrounded by wood framing on the north and east elevations.  Garage/Shed. This garage/shed is the larger of two sheds on the property. Estimated to have been built in the 1930s, it is rectangular in plan and is clad with flush, vertical wooden boards. It is covered with a shed roof that has exposed rafter tails and is clad with corrugated metal panels.  Shed #2. Shed #2 is a small rectangular shed. Estimated to have been built in the 1930s, it is clad with vertical wooden boards and has a shed roof clad with corrugated panels.  Main Barn. The main barn in a raised-center-aisle barn estimated to have been built in 1900. It is clad with vertical wooden boards. The roof is clad with corrugated metal panels. The north elevation has a large centered opening with chamfered corners as well as a sliding barn door. The south elevation has a sliding barn door and a large hinged door, as well as a hay carrier and hay doors under the gable peak. The east elevation features four open bays supported by square wooden posts.  Equipment Storage Building. This large building is estimated to have been built in 1938. It has a rectangular footprint and has four open bays on one side. The building is clad with vertical wooden boards. The shed roof is covered with corrugated aluminum panels and is supported by poles enhanced with Y braces. CHC 1-7 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 8  Warehouse. The large warehouse is estimated to have been built in the 1960s. It is rectangular in plan and is clad with vertical aluminum panels. It has a very low pitched, gabled roof. The east elevation features a single entry door (possibly metal), as well as a metal roll-up garage door and a rectangular vent with horizontal slats. The south elevation also has a metal roll-up garage door. Across the width of the north elevation is a shed supported by round metal poles. It has a flat roof clad with corrugated metal panels.  Former Spectators’ Barn/Viewing Stand. The former spectators’ barn/viewing stand has been converted to other farm uses. It is estimated to have been built ca. 1887 and is a two-story wood framed building clad with shiplap siding. It has a rectangular plan and a high pitched, side-gabled roof with boxed eaves. The northwest elevation features a strip of angled window openings that indicate the prior use as a race track viewing stand; the slant is likely a result of row seating and the open seating/viewing area was likely enclosed. Beneath this are two window openings which have been boarded over. Under the gable peak is a hay carrier and a pair of hay doors on hinges. A large concrete loading dock wraps around the southeast and southwest sides of the building. Along the southwest side of the building there is an addition that appears to have been constructed at a later date. The structure is clad with vertical wood boards and has a steeply pitched shed roof. 7.0 EVALUATION AND DISCUSSION 7.1 Historic Significance California Register (CRHR) The Draft EIR evaluated the complex as a whole and the significance of buildings individually. The evaluation found the complex as a whole significant locally under City historic significance criteria (discussed below), and under the California Register of Historic Resources (CRHR). The Dalidio Ranch Complex was found eligible for listing in the CRHR for its association with the early agricultural development of San Luis Obispo and as a representative of the 20th century vernacular architecture (Criterions 1 & 3). The main residence (Residence # 1) and main barn were found individually eligible under the CRHR. The main residence is constructed in a Craftsman style and retains many of its character-defining features such as clapboard and shiplap siding, shingles in the gable face, overhanging eaves and exposed rafter tails, decoratively cut knee braces and rafter tails, a wrap-around porch supported by square pillars, a shed-roofed dormer window, and various original wood windows. The main barn also embodies the raised- center-aisle type of barn. This structure retains its barn doors, hay doors, hay carriers and hardware, thus retaining much of its integrity. Therefore, the main residence and main barn are individually eligible for listing in the CRHR since they embody distinctive characteristics of Craftsman and vernacular architecture. CHC 1-8 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 9 Local Significance Criteria The project site is not currently within the City limits. Therefore, neither the project site nor any structures on the site are currently listed as historic resources. The Cultural Resources Evaluation found that the farm complex would be eligible under City Criterion B.2 (Event) and Criterion B.3 (Context) since the property exemplifies an important period of local history, being established as a family farm and developing into a valuable local agribusiness industry. The property is representative of early 20th century agricultural and industrial development. The Dalidio Ranch Complex, as well as cultivated fields, has existed on the property for over a century. The assemblage of ranch structures is a rare remaining and intact example of a farm complex representing the early agricultural history of San Luis Obispo. The main Craftsman style residence (Residence #1) and the main barn both embody the distinctive characteristics of Craftsman and vernacular agricultural architecture, retaining the majority of their character-defining features and integrity. As such, these two structures are individually eligible for designation as City of San Luis Obispo historic resources under Criterion A.1 (Style). 7.2 Cultural Resource Impacts The proposed project includes relocation and adaptive reuse of the existing main residence and the former spectators’ barn/viewing stand to new locations on the site within the Agricultural Heritage and Learning Center adjacent to the open space area to be preserved for agriculture. The Agricultural Heritage Facilities and Learning Center is intended to promote the region’s agricultural history. Uses proposed in the area include educational uses, urban agriculture, crop production, agriculture accessory uses, produce stands and temporary events4. Salvageable materials from the main barn are proposed to be reused to the greatest extent possible in the construction of a new barn in the Agricultural Heritage and Learning Center. Following relocation at the site of the Agricultural Heritage and Learning Center, the main residence and former spectators’ barn/viewing stand are proposed to be restored and adaptively reused following the Secretary of the Interior’s Standards. The proposed project would result in the demolition of the remaining structures included in the ranch complex, including the historic main barn once all useable materials have been salvaged. The Draft EIR Cultural Resources Evaluation concluded the project proposal would result in Class 1, Significant and Unavoidable Impacts to Historic Resources. The project would result in the demolition, relocation, and removal of structures which are individually identified as historic resources (Main Residence and Main Barn). The project would eliminate the San Luis Ranch Complex, which is eligible for listing as a historic resource. Relocation, demolition, and/or removal of these historic resources would permanently alter the historic context of the site and on-site structures. 4 Draft San Luis Ranch Specific Plan, Section 2.4.2 Agriculture CHC 1-9 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 10 7.2.1 Required Mitigation Measures. As described in the Draft EIR, the following mitigation measures would reduce the proposed project impacts on historical resources to the maximum extent practicable. Nevertheless, the project would result in a significant and unavoidable impact associated with the removal of individually historic structures that are part of the historically significant Dalidio/San Luis Ranch Complex. As such, the project would contribute to the cumulative loss of historic resources in the City. Therefore, the project would also result in a Class I, significant and unavoidable, cumulative impact to historical resources. CR-1(a) Historical Structure Relocation and Reconstruction Plan. In order to implement Specific Plan Policy 2.5, a relocation and reconstruction plan for the former spectator’s barn/viewing stand and main residence shall be developed by a qualified historic architect. The plan shall include a structural/architectural report documenting existing integrity and conditions and include detailed treatment methods and measures to ensure that historic integrity is retained and that all identified character defining features will be preserved. CR-1(b) Archival Documentation of Historic Buildings. The applicant shall provide archival documentation of the San Luis Ranch Complex in as-built and as- found condition in the form of a Historic American Building Survey (HABS) Level II documentation. The documentation shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990), and shall include large-format photographic recordation, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). The original archival-quality documentation shall be offered as donated material to the History Center of San Luis Obispo County. Archival copies of the documentation shall also be submitted to the San Luis Obispo County Library. CR-1(c) Informational Display of Historic Resources. A retrospective interpretive display detailing the history of the San Luis Ranch Complex and the project site, its significance, and its important details and features shall be developed by the applicant. The information should be incorporated into a publicly- accessed building on the project site, such as the proposed Agricultural Heritage Facilities and Learning Center, or a publicly-accessed outdoor location. The display shall include images and details from the HABS documentation described in Mitigation Measure CR-1(b) and any collected research pertaining to the historic property. The content shall be prepared by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). CHC 1-10 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 11 7.3 Archaeological Resources As described in the Draft EIR, one prehistoric archaeological site (SLR-S-01) has been identified and recorded on the project site. SLR-S-01 consists of a surface scatter of lithic artifacts (stone tool and chipped stone fragments) and one fragment of shell, with a subsurface component of redeposited lithic debitage (waste material from stone tool production). SLR-S- 01 is highly disturbed by repeated plowing, planting, harvesting, and other activities associated with crop cultivation. Although subsurface artifacts are present, they are limited to disturbed sediments above 40 centimeters below the surface, and do not represent an intact deposit. Based on the findings of the Cultural Resources Study, it is likely that the subsurface component consists of artifacts that were previously located on the surface scatter and have been redeposited due to remixing of sediments caused by agricultural activities. SLR-S-01 is not directly associated with important events or any persons significant in our past and, due to the absence of an intact subsurface component and lack of specific, interpretable context, the site is unlikely to yield important information about prehistory or history. As such, SLR-S-01 is not significant under CRHR Criteria 1, 2, 3 or 4. Therefore, the site is ineligible for listing in the CRHR and NRHP and requires no further management consideration under CEQA or the NHPA. Isolated artifacts (SLR-I-01 and SLR-I-02) have also been identified and recorded on the project site. The isolated artifacts consist of two flakes with moderate post-depositional damage. Under CEQA, the isolates are not eligible for listing in the CRHR. The information potential of isolates SLR-I-01 and SLR-I-02 and site SLR-S-01 has been exhausted by their recordation and analysis as part of the Cultural Resources Study. The surface of the project site has been previously disturbed by over 100 years of agricultural activities including planting, harvesting, and other activities associated with crop cultivation and thus the possibility of encountering undisturbed archaeological resources during construction is unlikely. Identified archaeological resources on the project site are ineligible for listing in the CRHR and NRHP, and disturbance of these resources would not constitute a significant impact. However, the potential remains for the project to result in impacts to previously unidentified archaeological resources. As outlined below, recommended mitigation measures include monitoring by a Native American monitor and a Secretary of Interior qualified professional archaeologist, and steps which are required to be taken in the event archaeological resources are exposed during construction. 7.3.1 Required Mitigation Measures. CR-2(a) Retain a Qualified Principal Investigator. In accordance with Conservation and Open Space Policies 3.5.6 and 3.5.7, a qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology (hereafter qualified archaeologist), shall be retained to carry out all mitigation measures related to archaeological and historical resources. CHC 1-11 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 12 Monitoring shall involve inspection of subsurface construction disturbance at or in the immediate vicinity of known sites, or at locations that may harbor buried resources that were not identified on the site surface. A Native American monitor shall also be present because the area is a culturally sensitive location. The monitor(s) shall be on-site on a full-time basis during earthmoving activities, including grading, trenching, vegetation removal, or other excavation activities. CR-2(b) Unanticipated Discovery of Archaeological Resources. In the event that archaeological resources are exposed during construction, all work shall be halted in the vicinity of the archaeological discovery until a qualified archaeologist can visit the site of discovery and assess the significance of the cultural resource. In the event that any artifact or an unusual amount of bone or shell is encountered during construction, work shall be immediately stopped and relocated to another area. The lead agency shall stop construction within 100 feet of the exposed resource until a qualified archaeologist/paleontologist can evaluate the find (see 36 CFR 800.11.1 and CCR, Title 14, Section 15064.5[f]). Examples of such cultural materials might include: ground stone tools such as mortars, bowls, pestles, and manos; chipped stone tools such as projectile points or choppers; flakes of stone not consistent with the immediate geology such as obsidian or fused shale; historic trash pits containing bottles and/or ceramics; or structural remains. If the resources are found to be significant, they must be avoided or will be mitigated consistent with State Historic Preservation Office (SHPO) Guidelines. 8.0 DRAFT EIR ALTERNATIVES ANALYSIS The Draft EIR presents an analysis of four alternatives (Draft EIR section 6.0) to the proposed project. Draft EIR section 6.0, Alternative #3, assumes the San Luis Ranch Farm Complex, as well as associated eucalyptus trees located in the northwest portion of the site would be retained, and that the proposed multi-family residential development would be relocated and integrated into the area currently proposed for single-family development. The complete alternatives analysis can be found on the City website at: http://www.slocity.org/Home/ShowDocument?id=14347 Overall, the alternatives analysis found the historic preservation Alternative #3 would avoid significant and unavoidable impacts to historic resources and would reduce other potential environmental effects due to the preservation of the eucalyptus grove in the northwest portion of the site along Madonna Road, and due to the reduced overall development footprint. Alternative #3 was also discussed in the EIR as feasible, and would likely reduce impacts to air quality, GHG emissions, noise, biological resources, land use/policy consistency, and hydrology and water quality, while resulting in slightly increased impacts to transportation (due to the loss of the proposed San Luis Ranch Way access route). Alternative 3 was also evaluated as the CHC 1-12 SPEC/ANNX/EIR-1502-2015; 1035 Madonna Road (San Luis Ranch Project) Cultural Heritage Committee Report – January 23, 2017 Page 13 environmentally superior alternative5. 9.0 ATTACHMENTS 1.

(Rincon) in August 2016 (Appendix G) and the 2014 LUCE Update EIR. 4.5.1 Setting a. Prehistoric Setting. The project site is located within what is generally described as the Central Coast archaeological region, which one of eight organizational divisions of California (Jones and Klar 2007, Moratto 1984). The Central Coast archaeological region extends from Monterey Bay to Morro Bay, and includes the County of San Luis Obispo. The prehistoric cultural chronology for the Central Coast is generally divided into six periods: Paleo-Indian (ca. 10,000 – 6,000 B.C.), Milling Stone (6,000 - 3,000 B.C.), Early and Early-Middle Transition (3,000 - 600 B.C.), Middle (600 B.C. - A.D. 1000), Middle-Late Transition (A.D. 1000 - A.D. 1250), and Late (A.D. 1250 - historic contact [ca. A.D. 1769]) (Jones and Klar 2007). Several chronological sequences have been devised to understand cultural changes along the Central Coast from the Millingstone Period to contact. Jones (1993) and Jones and Waugh (1995) presented a Central Coast sequence that integrates data from archaeological studies conducted since the 1980s. Three periods, including the Early, Middle, and Late periods, are presented in their prehistoric sequence subsequent to the Millingstone Period. More recently, Jones and Ferneau (2002) updated the sequence following the Millingstone Period as follows: Early, Early- Middle Transition, Middle, Middle-Late Transition, and Late periods. The archaeology of the Central Coast subsequent to the Millingstone Period is distinct from that of the Bay Area to the north and Central Valley to the east. The region has more in common with the Santa Barbara Channel area during the Middle and Middle-Late Transition periods, but few similarities during the Late period (Jones & Ferneau 2002). b. Historical Setting. Post-European contact history for California is generally divided into three periods: the Spanish Period (1769–1822), the Mexican Period (1822–1848), and the American Period (1848–present). The Spanish Period brought the establishment of the California mission system, while the Mexican Period is largely known for the division of the land of California into private land holdings. Following the Mexican-American war, the United States purchased California from Mexico; population of the state subsequently increased, particularly during the Gold Rush. Following the arrival of the first Europeans, Mission San Luis Obispo de Tolosa was founded in 1772 by Padre Junipero Serra. The population of native people at the mission declined rapidly. In 1803, there was a peak of 919 Native Americans residing at the mission, but by 1838 the population had declined to 170. In 1822 California became a Mexican Territory, and the mission lands gradually became private ranchos through Mexican land grants. In 1846, the Bear Flag Rebellion resulted in California’s independence from Mexico, and control of the territory soon fell into the hands of the United States. Beginning in 1873, the County experienced a steady change in land use and recorded more acreage under cultivation each year. The California State Board of Agriculture reported that in 1910 the County had 1,566,660 acres of farmland. Over the following decades, the San Luis Obispo area continued to operate as agricultural and ranching property. CHC 1-14 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-2 Agriculture in San Luis Obispo. By the early 20th century, the land surrounding Laguna Lake developed into farms, dairies, and ranches (Bertrando 1999a). Wool, flour, and dairy were important income-generating products in the area. Some of the most important agricultural crops in the late 1800s were wheat, barley, and beans. Grain from area ranchos was processed at local mills. Production increased when steam-powered mills were constructed starting in the 1870s. Ranching and agriculture were the region’s main commercial enterprises at one time and thus had an impact on the development of the city (Historic Resources Group [HRG] 2013). Because San Luis Obispo was the largest settlement in the area, some ranchers would travel from up to forty miles away to bring their grains into the city to be milled. As a result, roads were constructed throughout the County in the 1870s, primarily by Chinese laborers, leading to increased mobility in the region. In 1872, Captain John Harford began construction on the Pacific Coast Railway which ran just to the east of the Specific Plan Area. The railway improved shipping methods of local crops and products, advancing the economy (HRG 2013). A dairy industry began developing in San Luis Obispo County in the late 1860s after the drought years of 1862-64. During the 1880s beans were the primary crop grown south of the city and continued into the early years of the 20th century (Bertrando 1999b). Other significant agricultural crops in the area in the early 20th century included winter peas, celery and flower seed. Japanese farmers in particular were successful with these crops through the 1930s. Horse Racing in San Luis Obispo. Horse racing was documented to be a popular sport in the region since the time of the Mexican ranchos in the first half of the 19th century (Angel 1883). Historical newspaper articles discuss the establishment of horse racing tracks in the San Luis Obispo area from 1874 through 1887. During this period a half-mile race track was located in the vicinity of Madonna Plaza, which would be slightly to the northeast of the project site (Bertrando 1999a). After 1901, ownership of the portion of the project site with the spectators’ barn/viewing stand changed hands, and the spectators’ barn/viewing stand was reportedly moved to its current location on the northwest portion of the project site, near Madonna Road. It was reported that when the spectators’ barn/viewing stand was moved into the project site, the track was shortened by a half mile (Froom in Bertrando, 1998). c. Project Site Historic Context. The project site is comprised of several lots that were subdivided in 1875, when the Laguna Rancho was sold off into plots for small family farms. Each property consisted of a farm complex with a home (Bertrando 1999a). A horse race track facility, which included stables and a spectators’ barn/viewing stand, was originally located in the current agricultural area of the site. After 1910, the horse race track facility was moved to its current location on the northwest portion of the project site, near Madonna Road. A kitchen and cocktail lounge that once existed on opposite ends of the viewing stand were removed and utilized for the construction of a small family residence. The stables that had been associated with the race track were removed from the site and the spectators’ barn/viewing stand was further altered by the addition of a dairy, stables and conversion of the spectator seating area to hay storage. In approximately 1921, the Dalidio family purchased the project site and converted the site to farmed crops such as onions, artichokes, and garbanzo beans, as well as flowers for seed (Bertrando 1999a; Stewart 1999). The agricultural business on the project site was known as Zapata Farms starting in the early 1980s (Bertrando 1999a; Stewart 1999). The property changed ownership again in 2014 and it has recently been known as the San Luis Ranch. For a detailed CHC 1-15 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-3 history of the region and the San Luis Ranch Specific Plan Area, refer to the Cultural Resources Study in Appendix G to this EIR. The former spectators’ barn/viewing stand, as well as other on-site structures, is described in detail in Section 4.5.1(d). d. Documented Cultural Resources. Previously Documented Archaeological and Historical Resources. On January 25, 2016 Rincon requested a search of the cultural resource records housed at the California Historical Resources Information System (CHRIS) Central Coast Information Center (CCIC) located at University of California, Santa Barbara. The search included a review of the National Register of Historic Places (NRHP), the California Register of Historical Resources (CRHR), the California State Historical Landmarks list, the California Points of Historical Interest list, historic building surveys, the Archaeological Determinations of Eligibility list, and the California Inventory of Historical Resources list. The records search provided information about archaeological resources, historic resources, and reports within the project site as well as within a 0.5-mile radius of the project site. The records search identified 51 reports of studies previously conducted within the project site as well as within a 0.5-mile radius of the project site. Of these records, eight previous studies overlap with or were located within the project site. The National Archaeological Database listing summary for these studies is presented in Appendix B of the Cultural Resources Study prepared for the project by Rincon in August 2016 (refer to Appendix G to this EIR). The previous studies conducted within and in the vicinity of the project site did not identify any archaeological resources on the project site. In addition, the CCIC did not list any historic addresses on the project site, nor does the CCIC possess any historical maps that indicate the presence of historic resources on the project site. However, the CCIC records search identified nine previously recorded archaeological and historical resources located within a 0.5-mile radius of the project site, described in detail in Appendix G to this EIR. Of these resources, one identified historic resource is located on the project site: the San Luis Ranch Complex (P-40- 041000). The San Luis Ranch Complex, formerly known as the Dalidio Ranch Complex, is located on the northwest portion of the project site, near Madonna Road. Singer and Atwood (1988) conducted a cultural resources survey of the project site in 1988, and identified “two wood frame structures, a large, two-story house and a barn” as having potential historical significance. Betsy Bertrando recorded and evaluated the Complex in 1999 and identified eight historic built environment resources including the Dalidio home, a bungalow, a small shed/bunkhouse, a garage, a water tower, the main barn, a large equipment storage building, and the spectators’ barn/viewing stand. The San Luis Ranch Complex presently includes nine structures, described in detail below. The water tower that was recorded on the project site in the 1999 Bertrando analysis was not observed during the investigation for the current project. Archaeological and Historical Resources on the Project Site. Archaeological Resources. Rincon staff conducted a pedestrian field survey of the project site for archaeological resources between March 14, 2016 and March 16, 2016. During this field survey, Rincon identified and recorded three prehistoric archaeological resources on the project site. These resources include one prehistoric archaeological site (SLR-S-01) and two isolated prehistoric artifacts (SLR-I-01 and SLR-I-02). Between August 1, 2016 and August 16, 2016, CHC 1-16 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-4 Rincon conducted test excavations, including one test unit, two shovel test pits, and 21 auger tests, of archaeological site SLR-S-01 to evaluate the CRHR eligibility of the site. The three resources identified on the project site include: • SLR-S-01. SLR-S-01 is a prehistoric lithic scatter. The site measures 170 × 315 feet and consists of a surface scatter of lithic artifacts and one fragment of shell, with a subsurface component of redeposited lithic debitage (waste material from stone tool production) extending to 40 centimeters below the surface. During the pedestrian survey, Rincon identified the site as a surface scatter of flaked stone debitage, all composed of cryptocrystalline silicate (CCS) materials including Franciscan and Monterey cherts. • SLR-I-01. SLR-I-01 consists of an isolated prehistoric grayish-brown cortical CCS flake measuring 4.8 x 3.6 x 1 centimeters. The flake exhibits moderate post-depositional damage. • SLR-I-02. SLR-I-02 consists of an isolated prehistoric brownish-red cortical CCS flake measuring 3.0 x 2.3 x 0.7 centimeters. The flake exhibits moderate post-depositional damage. Built Environment Resources. As shown in Figure 4.5-1, the project site currently contains a grouping of nine structures at the northwest end of the property, collectively known as the San Luis Ranch Complex. The San Luis Ranch Complex includes three single-family residences, a garage/shed, a smaller shed, the main barn, a large equipment storage building, a warehouse, and the former spectators’ barn/viewing stand, which was converted to farm use. Figures 4.5- 2a through 4.5-2e provide photographs of each of these structures. The following is a summarized description of each of the structures within the San Luis Ranch Complex: • Main Residence (Residence #1). The main residence is a single-family residence estimated to have been built ca. 1910. It is irregular in plan and built in the Craftsman style. This structure features a high pitched, front-gabled roof, with overhanging eaves and exposed rafter tails. The roof is clad in composition shingles. There is a shed dormer on the northeast side of the roof. On the southwest side a hipped roof extension covers the wrap-around porch and a cantilevered box bay window. The home is clad with shiplap and clapboard siding as well as shingles on the gable face. • Residence #2. This single family home is estimated to have been built ca. 1900-1910. It is rectangular in plan and appears to have a small addition on the east elevation as well as a shed extension on the south. The eastern addition includes a chimney. Both the main portion of the home and the addition feature medium pitched front-gabled roofs and an open eave overhang with fascia boards. The roof is clad with composite shingles. The shed extension features a nearly flat roof partially clad with corrugated panels. Residence #3. This single family home is estimated to have been built in the 1960s. It is roughly square in plan, clad with reverse board and batten and has a side-gabled roof clad with composition shingles. There are horizontally slatted vents under the gable peaks. The home features aluminum sliding windows surrounded by wood framing on the north and east elevations.

This garage/shed is the larger of two sheds on the property. Estimated to have been built in the 1930s, it is rectangular in plan and is clad with flush, vertical wooden boards. It is covered with a shed roof that has exposed rafter tails and is clad with corrugated metal panels. •Shed #2. Shed #2 is a small rectangular shed. Estimated to have been built in the 1930s, it is clad with vertical wooden boards and has a shed roof clad with corrugated panels. •Main Barn. The main barn in a raised-center-aisle barn estimated to have been built in 1900. It is clad with vertical wooden boards. The roof is clad with corrugated metal panels. The north elevation has a large centered opening with chamfered corners as well as a sliding barn door. The south elevation has a sliding barn door and a large hinged door, as well as a hay carrier and hay doors under the gable peak. The east elevation features four open bays supported by square wooden posts. •Equipment Storage Building. This large building is estimated to have been built in 1938. It has a rectangular footprint and has four open bays on one side. The building is clad with vertical wooden boards. The shed roof is covered with corrugated aluminum panels and is supported by poles enhanced with Y braces. •Warehouse. The large warehouse is estimated to have been built in the 1960s. It is rectangular in plan and is clad with vertical aluminum panels. It has a very low pitched, gabled roof. The east elevation features a single entry door (possibly metal), as well as a metal roll-up garage door and a rectangular vent with horizontal slats. The south elevation also has a metal roll-up garage door. Across the width of the north elevation is a shed supported by round metal poles. It has a flat roof clad with corrugated metal panels. •Former Spectators’ Barn/Viewing Stand. The former spectators’ barn/viewing stand has been converted to other farm uses. It is estimated to have been built ca. 1887 and is a two-story wood framed building clad with shiplap siding. It has a rectangular plan and a high pitched, side-gabled roof with boxed eaves. The northwest elevation features a strip of angled window openings that indicate the prior use as a race track viewing stand; the slant is likely a result of row seating and the open seating/viewing area was likely enclosed. Beneath this are two window openings which have been boarded over. Under the gable peak is a hay carrier and a pair of hay doors on hinges. A large concrete loading dock wraps around the southeast and southwest sides of the building. Along the southwest side of the building there is an addition that appears to have been constructed at a later date. The structure is clad with vertical wood boards and has a steeply pitched shed roof. e.Regulatory Setting Federal Regulations. The project does not involve federal funding or permitting, and as a result, does not have a federal nexus. Therefore, compliance with reference to the National Historic Preservation Act of 1966 (NHPA) and other federal laws is provided here for informational purposes only. National Register of Historic Places. The NRHP was established by the NHPA to help identify properties that are significant cultural resources at the national, state, and/or local level. To be eligible for listing in the NRHP, a resource must be significant in American history, architecture, archaeology, engineering, or culture. Districts, sites, buildings, structures, and objects of potential significance must also possess integrity of location, design, setting, CHC 1-24 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-12 materials, workmanship, feeling, and association. A property is eligible for the NRHP if it meets one or more of the following criteria: A: It is associated with events that have made a significant contribution to the broad patterns of our history; B: It is associated with the lives of persons who are significant in our past; C: It embodies the distinctive characteristics of a type, period, or method of construction, or represents the work of a master, or possesses high artistic values, or represents a significant and distinguishable entity whose components may lack individual distinction; and/or D: It has yielded, or may be likely to yield, information important in prehistory or history. As described in the Cultural Resources Study (see Appendix G), San Luis Ranch (formerly Dalido Ranch) began as a family farm and expanded into a larger agribusiness. The property has retained a complex of ranch buildings and cultivated fields for over a century. The property was owned for many decades by the Dalidio family, who has been involved in the regional dairy industry and agribusiness. Their contributions are believed to be of local significance, not statewide or nationwide. Thus, the Dalidio family’s contributions do not make the property or complex eligible for listing in the NRHP. The property and the structures on the property are also not expected to yield important information about prehistory or history and do not demonstrate sufficient historical significance in national, state, or local agricultural development or as a unique property type to warrant listing in the NRHP. State Regulations. Assembly Bill 52. Assembly Bill 52 (AB 52) amends Public Resources Code (PRC) Section 5097.94 (CEQA) and adds eight new sections to the PRC relating to Native Americans. It was passed and signed into law in 2014 and took effect on July 1, 2015. This law establishes a new category of resource called tribal cultural resources (PRC Section 21074) and establishes a process for consulting with Native American tribes and groups regarding those resources. The consultation process must be completed before a CEQA document can be certified. Native American tribes to be included in the process are identified through consultation with the California Native American Heritage Commission (NAHC) (PRC Section 21080.3.1). Tribal cultural resources are “[s]ites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe…” (PRC Section 21074.1). A tribal cultural resource must be on, or eligible for, the CRHR as described above for historical resources, or must be included in a local register of historical resources. Also as discussed above for historical resources, the lead agency can determine that a tribal cultural resource is significant even if it has not been evaluated as eligible for the CRHR or is not on a local register. Assembly Bill 52 establishes that “A project with an effect that may cause a substantial adverse change in the significance of a tribal cultural resource is a project that may have a significant effect on the environment” (PRC Section 21084.2). It further states that the lead agency shall establish measures to avoid impacts that would alter the significant characteristics of a tribal cultural resource, when feasible (PRC Section 21084.3). The City conducted Native American consultation consistent with Senate Bill 18 and Assembly Bill 52 for the project, which is described in Section 4.5.3(a), Methodology. CHC 1-25 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-13 Senate Bill 18. Passed in 2004, Senate Bill 18 (SB 18) requires cities and counties to consult with Native American tribes to help protect traditional tribal cultural places through the land use planning process. Unlike AB 52, SB 18 is not an amendment to, or otherwise associated with, CEQA. Instead, SB 18 requires cities and counties to consult with Native American tribes early during broad land use planning efforts on both public and private lands, prior to site- and project-specific land use decisions. The bill applies to general plan adoption or amendments and to specific plan adoption or amendments. A Native American tribe is defined as “a federally recognized California Native American tribe or a non-federally recognized California Native American tribe that is on the contact list maintained by the Native American Heritage Commission” (Governor’s Office of Planning and Research 2005). Traditional tribal cultural places are defined in PRC Sections 5097.9 and 5097.993 to include sanctified cemeteries, places of worship, religious or ceremonial sites, or sacred shrines, or any historic, cultural, or sacred site that is listed on or eligible for the CRHR including any historic or prehistoric ruins, burial grounds, or archaeological site (Governor’s Office of Planning and Research 2005). Under SB 18, cities and counties must notify the appropriate Native American tribe(s) of intended adoption or amendments to general plans or specific plans, and offer the opportunity for the tribe(s) to consult regarding traditional tribal cultural places within the proposed plan area. Consultation is intended to encourage preservation and protection of traditional tribal cultural places by developing treatment and management plans that might include incorporating the cultural places into designated open spaces (Governor’s Office of Planning and Research 2005). California Environmental Quality Act. CEQA requires a lead agency to determine whether a project may have a significant effect on historical resources (Public Resources Code [PRC], Section 21084.1). A historical resource is a resource listed, or determined to be eligible for listing, in the CRHR; a resource included in a local register of historical resources; or any object, building, structure, site, area, place, record, or manuscript that a lead agency determines to be historically significant (State CEQA Guidelines, Section 15064.5[a][1-3]). A resource may be eligible for inclusion in the CRHR if it meets one or more of the following criteria: 1. Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; 2. Is associated with the lives of persons important in our past; 3. Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or 4. Has yielded, or may be likely to yield, information important in prehistory or history. The San Luis Ranch Complex is eligible for listing in the CRHR under Criterion 1 for its association with the early agricultural development of San Luis Obispo. The San Luis Ranch property has retained the complex of ranch buildings and cultivated fields for over a century. The property is also representative of an early 20th century farm with its associated buildings, agricultural fields and ancillary structures. The buildings reflect the distinctive characteristics of the early 20th century vernacular agricultural architecture, making the San Luis Ranch Complex also eligible for listing in the CRHR under Criterion 3. CHC 1-26 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-14 Individual buildings within the San Luis Ranch Complex also embody distinctive characteristics of a type, period, region, or method of construction. The main residence (Residence # 1) is constructed in a Craftsman style and retains many of its character-defining features such as clapboard and shiplap siding, shingles in the gable face, overhanging eaves and exposed rafter tails, decoratively cut knee braces and rafter tails, a wrap-around porch supported by square pillars, a shed-roofed dormer window, and various original wood windows. The main barn also embodies the raised-center-aisle type of barn. This structure retains its barn doors, hay doors, hay carriers and hardware, thus retaining much of its integrity. Therefore, the main residence and main barn are individually eligible for listing in the CRHR under Criterion 3. In addition, if a project can be demonstrated to cause damage to a unique archaeological resource, the lead agency may require reasonable efforts to permit any or all of these resources to be preserved in place or left in an undisturbed state. To the extent that resources cannot be left undisturbed, mitigation measures are required (PRC, Section 21083.2[a], [b], and [c]). PRC, Section 21083.2(g) defines a unique archaeological resource as an artifact, object, or site about which it can be clearly demonstrated that, without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria: 1. Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information; or 2. Has a special and particular quality such as being the oldest of its type or the best available example of its type; or 3. Is directly associated with a scientifically recognized important prehistoric or historic event or person. According to CEQA, all buildings constructed over 50 years ago and that possess architectural or historical significance may be considered potential historic resources. Most resources must meet the 50-year threshold for historic significance; however, resources less than 50 years in age may be eligible for listing on the CRHR if it can be demonstrated that sufficient time has passed to understand their historical importance. Codes Governing Human Remains. Section 15064.5 of the CEQA Guidelines also assigns special importance to human remains and specifies procedures to be used when Native American remains are discovered. The disposition of human remains is governed by Health and Safety Code Section 7050.5 and PRC Sections 5097.94 and 5097.98, and falls within the jurisdiction of the NAHC. If human remains are discovered, the County Coroner must be notified within 48 hours and there should be no further disturbance to the site where the remains were found. If the remains are determined by the coroner to be Native American, the coroner is responsible for contacting the NAHC within 24 hours. The NAHC, pursuant to PRC Section 5097.98, will immediately notify those persons it believes to be most likely descended from the deceased Native Americans so they can inspect the burial site and make recommendations for treatment or disposal. Local Regulations. The project is subject to local measures, including the City’s Historic Preservation Ordinance, the City’s General Plan, and the San Luis Obispo Municipal Code. These regulations are discussed below. CHC 1-27 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-15 Historic Preservation Ordinance. In 2010, the City of San Luis Obispo passed a Historic Preservation Ordinance to identify and protect important historic resources within the city (City of San Luis Obispo 2010). When determining if a property should be designated as a listed Historic or Cultural Resource, the Cultural Heritage Commission and City Council are to consider this ordinance and SHPO standards. To be eligible for designation, the resource shall exhibit a high level of historic integrity, be at least 50 years old (less than 50 if it can be demonstrated that enough time has passed to understand its historical importance) and satisfy at least one of the following criteria: A. Architectural Criteria: Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master, or possesses high artistic values. (1) Style: Describes the form of a building, such as size, structural shape and details within that form (e.g. arrangement of windows and doors, ornamentation, etc.). Building style will be evaluated as a measure of: a. The relative purity of a traditional style; b. Rarity of existence at any time in the locale; and/or current rarity although the structure reflects a once popular style; c. Traditional, vernacular and/or eclectic influences that represent a particular social milieu and period of the community; and/or the uniqueness of hybrid styles and how these styles are put together. (2) Design: Describes the architectural concept of a structure and the quality of artistic merit and craftsmanship of the individual parts. Reflects how well a particular style or combination of styles are expressed through compatibility and detailing of elements. Also, suggests degree to which the designer (e.g., carpenter-builder) accurately interpreted and conveyed the style(s). Building design will be evaluated as a measure of: a. Notable attractiveness with aesthetic appeal because of its artistic merit, details and craftsmanship (even if not necessarily unique); b. An expression of interesting details and eclecticism among carpenter-builders, although the craftsmanship and artistic quality may not be superior. (3) Architect: Describes the professional (an individual or firm) directly responsible for the building design and plans of the structure. The architect will be evaluated as a reference to: a. A notable architect (e.g., Wright, Morgan), including architects who made significant contributions to the state or region, or an architect whose work influenced development of the city, state or nation. b. An architect who, in terms of craftsmanship, made significant contributions to San Luis Obispo (e.g., Abrahams who, according to local sources, designed the house at 810 Osos - Frank Avila’s father’s home - built between 1927 – 30). B. Historic Criteria: (1) History – Person: Associated with the lives of persons important to local, California, or national history. Historic person will be evaluated as a measure of the degree to which a person or group was: a. Significant to the community as a public leader (e.g., mayor, congress member, etc.) or for his or her fame and outstanding recognition - locally, regionally, or nationally. CHC 1-28 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-16 b. Significant to the community as a public servant or person who made early, unique, or outstanding contributions to the community, important local affairs or institutions (e.g., council members, educators, medical professionals, clergymen, railroad officials). (2) History – Event: Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. Historic event will be evaluated as a measure of: a. A landmark, famous, or first-of-its-kind event for the city - regardless of whether the impact of the event spread beyond the city. b. A relatively unique, important or interesting contribution to the city (e.g., the Ah Louis Store as the center for Chinese-American cultural activities in early San Luis Obispo history). (3) History-Context: Associated with and also a prime illustration of predominant patterns of political, social, economic, cultural, medical, educational, governmental, military, industrial, or religious history. Historic context will be evaluated as a measure of the degree to which it reflects: a. Early, first, or major patterns of local history, regardless of whether the historic effects go beyond the city level, that are intimately connected with the building (e.g., County Museum). b. Secondary patterns of local history, but closely associated with the building (e.g., Park Hotel). C. Integrity: Authenticity of an historical resource’s physical identity evidenced by the survival of characteristics that existed during the resource’s period of significance. Integrity will be evaluated by a measure of: (1) Whether or not a structure occupies its original site and/or whether or not the original foundation has been changed, if known. (2) The degree to which the structure has maintained enough of its historic character or appearance to be recognizable as an historic resource and to convey the reason(s) for its significance. (3) The degree to which the resource has retained its design, setting, materials, workmanship, feeling and association. The project site is not currently within the City limit. Therefore, neither the project site nor any structures on the site are currently listed as a Historic or Cultural Resource according to the above criteria. However, the San Luis Ranch property exemplifies an important period of local history, being established as a family farm and developing into a valuable local agribusiness industry. The property is representative of early 20th century agricultural and industrial development. The San Luis Ranch Complex, as well as cultivated fields, has existed on the property for over a century. The San Luis Ranch Complex is a rare remaining and intact example of a farm complex representing the early agricultural history of San Luis Obispo. Therefore, it is eligible for designation as a City of San Luis Obispo historic resource under Criterion B.2 (Event) and Criterion B.3 (Context). The main Craftsman style residence (Residence #1) and the main barn both embody the distinctive characteristics of Craftsman and vernacular agricultural architecture, retaining the majority of their character-defining features and integrity. As such, these two structures are individually eligible for designation as City of San Luis Obispo historic resources under Criterion A.1 (Style). CHC 1-29 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-17 City of San Luis Obispo General Plan. The Conservation and Open Space Element of the General Plan addresses historic and architectural Resources within the City. New development is evaluated for consistency with the following adopted goals and policies relating to archaeological and historical resources: Goal 3.2. Historic and Architectural Resources. The City will expand community understanding, appreciation, and support for historic and architectural resource preservation to ensure long-term protection of cultural resources. Policy 3.3.1. Historic Preservation. Significant historic and architectural resources should be identified, preserved, and rehabilitated. Policy 3.3.2. Demolitions. Historically or architecturally significant buildings shall not be demolished or substantially changed in outward appearance, unless doing so is necessary to remove a threat to health and safety and other means to eliminate or reduce the threat to acceptable levels are infeasible. Policy 3.3.3. Historical Documentation. Buildings and other cultural features that are not historically significant but which have historical or architectural value should be preserved or relocated where feasible. Where preservation or relocation is not feasible, the resources shall be documented and the information retained in a secure but publicly accessible location. An acknowledgement of the resources should be incorporated within the site through historic signage and the reuse or display of historic material and artifacts. Goal 3.4. Historic and Architectural Resources. The City will expand community understanding, appreciation, and support for archaeological resource preservation. Policy 3.5.1. Archaeological Resource Protection. The City shall provide for the protection of both known and potential archaeological resources. To avoid significant damage to important archaeological sites, all available measures, including purchase of the property in fee or easement, shall be explored at the time of a development proposal. Where such measures are not feasible and development would adversely affect identified archaeological or paleontological resources, mitigation shall be required pursuant to the Archaeological Resource Preservation Program Guidelines. Policy 3.5.2. Native American Sites. All Native American cultural and archaeological sites shall be protected as open space wherever possible. Policy 3.5.3. Non-Development Activities. Activities other than development which could damage or destroy archaeological sites, including off-road vehicle use on or adjacent to known sites, or unauthorized collection of artifacts, shall be prohibited. Policy 3.5.4. Archaeological Sensitive Areas. Development within an archaeologically sensitive area shall require a preliminary site survey by a qualified archaeologist knowledgeable in Native American cultures, prior to a determination of the potential environmental impacts of the project. Policy 3.5.5. Archaeological Resources Present. Where a preliminary site survey finds substantial archaeological resources, before permitting construction, the City shall require a mitigation plan to protect the resources. Possible mitigation measures include: presence of a CHC 1-30 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-18 qualified professional during initial grading or trenching; project redesign; covering with a layer of fill; excavation removal and curation in an appropriate facility under the direction of a qualified professional. Policy 3.5.6. Qualified Archaeologist Present. Where substantial archaeological resources are discovered during construction or grading activities, all such activities in the immediate area of the find shall cease until a qualified archaeologist knowledgeable in Native American cultures can determine the significance of the resource and recommend alternative mitigation measures. Policy 3.5.7. Native American Participation. Native American participation shall be included in the City’s Guidelines for resource assessment and impact mitigation. Native American representatives should be present during archaeological excavation and during construction in an area likely to contain cultural resources. The Native American community shall be consulted as knowledge of cultural resources expands and as the City considered updates or significant changes to its General Plan. Policy 3.6.3. Construction within Historic Districts. The Cultural Heritage Committee and Architectural Review Commission will provide specific guidance on the construction of new buildings within historic districts. Municipal Code. In addition to the City of San Luis Obispo’s requirements to designate a Historic or Cultural Resource, the City Municipal Code contains specific requirements for the demolition and relocation of structures listed in the inventory of historic resources. These requirements are stated in Municipal Code sections 14.01.100 and 14.01.110. The City Municipal Code states that the Cultural Heritage Committee (CHC) shall review and make recommendations to the City Council regarding demolition applications for structures listed in the inventory of historic resources. An application for demolition of a listed historic resource shall be approved only if the proposed demolition is found consistent with the general plan and 1) the historic resource is a hazard to public health of safety, and repair or stabilization is not structurally feasible; or 2) denial of the application will constitute an economic hardship as described in section 14.01.100(J)(1-3) of the municipal code. Additional procedures regarding the timing of the demolition, documentation and acknowledgment of the historic resource are also delineated. Likewise, the relocation of a structure listed on the inventory of historic resources is subject to review by the CHC and Architectural Review Commission (ARC). Relocation shall be permitted only when relocation is consistent with the goals and policies of the general plan, any applicable area or specific plans, and the Historic Preservation Program Guidelines, as well as additional criteria defined in Municipal Code Section 14.01.110(B)(1-6). The timing, plan, procedures and documentation are also delineated. City of San Luis Obispo Archaeological Resource Preservation Guidelines. The Archaeological Resource Preservation Guidelines (part of the City’s Environmental Guidelines) developed by the San Luis Obispo CHC are used to determine whether a project complies with CEQA, as well as the information needed to evaluate a project’s effects on archaeological sites and artifacts. The Guidelines call for a three-step approach to historical resources: preparation of an Archaeological and Architectural Resource Inventory (ARI); Subsurface Archaeological CHC 1-31 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-19 Resource Evaluation (SARE); and Archaeological Resource Impact Mitigation (ARIM). These steps parallel the CEQA process. 4.5.2 Previous Program-Level Environmental Review The 2014 Land Use and Circulation Elements Update EIR (LUCE Update EIR) previously analyzed Citywide impacts to cultural resources, including those associated with development on the San Luis Ranch Specific Plan Area, related to the adoption and implementation of the Land Use and Circulation Element policies and programs. The LUCE Update EIR cultural resources analysis determined that the intensification of land uses anticipated to occur in certain areas of the City under the Land Use and Circulation Element update, including the San Luis Ranch Specific Plan area, could have an adverse effect on historic structures, as well as identified and previously unidentified archaeological and paleontological resources, including human remains. However, the LUCE Update EIR concluded that implementation of LUCE Update EIR Mitigation Measures CR-1 through CR-3, which changed the language of General Plan Conservation and Open Space Policies 3.3.2, 3.3.5, 3.5.10 to be more stringent in order to better facilitate the protection of the City’s historical resources, as well as various other General Plan policies regarding cultural and paleontological resources, would reduce impacts to historic structures and archaeological and paleontological resources to a less than significant level. 4.5.3 Impact Analysis a. Methodology and Significance Thresholds for Cultural Resources. If a project may cause a substantial adverse change in the characteristics of a resource that convey its significance or justify its eligibility for inclusion in the CRHR or a local register, either through demolition, destruction, relocation, alteration, or other means, then the project is judged to have a significant effect on the environment (CEQA Guidelines, Section 15064.5[b]). The following thresholds are based on Appendix G of the State CEQA Guidelines. Impacts would be significant if the project would: 1. Cause a substantial adverse change in the significance of a historic resource as defined in §15064.5; 2. Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5; 3. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature; or 4. Disturb any human remains, including those interred outside of formal cemeteries. The Initial Study determined that the project would not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature. Therefore, Threshold 3 is not discussed further in this section. Refer to Section 4.14, Issues Addressed in the Initial Study, for a discussion of this issue. Direct impacts can be assessed by identifying the types and locations of proposed development, determining the exact locations of cultural resources within the project area, assessing the significance of the resources that may be affected, and determining the appropriate mitigation. Removal, demolition, or alteration of historical resources can permanently impact the historic fabric of an archaeological site, structure, or historic district. CHC 1-32 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-20 Methodology. The analysis within this section builds upon the conclusions identified in the LUCE Update EIR, as described in Section 4.5.2. Where applicable, this analysis includes mitigation that implements applicable City policies for the protection of archaeological and historical resources. A Cultural Resources Study of the project site and vicinity was completed in August 2016 (Appendix G). As described in Section 4.5.1(d), as part of the Cultural Resources Study, a records search was obtained from the CCIC. The search was conducted to identify previous cultural resources evaluations and previously recorded cultural resources on the project site as well as within a 0.5-mile radius of the project site. In addition to the records search, the Cultural Resources Study included archival research for the project site. The methodology for the archival research focused on the review of primary and secondary source materials related to the history and development of the project site and vicinity. Sources for this research included historic maps, aerial photographs, and written histories of the area. In addition, Rincon staff conducted a pedestrian survey of the project site for archaeological resources between March 14, 2016 and March 16, 2016. On March 15, 2016 Rincon staff also conducted survey of the project site for historic resources, which included examination, documentation, photographing, and evaluating the built environment features on the project site. Between August 1, 2016 and August 16, 2016, Rincon staff conducted test excavations to evaluate the CRHR eligibility of the prehistoric lithic scatter located on the western edge of the project site (SLR-S-01). During archaeological testing all identified surface artifacts were also collected for temporary storage, cataloging, and analysis. All data was recorded on standard archaeological forms. All excavations were backfilled upon completion of testing. Rincon conducted Native American consultation consistent with Senate Bill 18 and Assembly Bill 52 for the project to identify potential concerns or issues associated with Native American cultural resources within the project vicinity. Rincon contacted the NAHC to determine whether any sites recorded in the NAHC’s Sacred Lands File occur in or near the project site. The NAHC responded on January 27, 2016 stating that the search of the sacred land files “failed to indicate the presence of Native American cultural resources in the immediate project area.” In addition, the NAHC provided a list of Native American groups and individuals who may have knowledge of cultural resources within the project site. The Native American scoping did not identify any identify any specific resources important to the consulted groups within the project site. However, several contacts noted that the area is sensitive. All Native American parties contacted about the project site are described in the Cultural Resource Study (Appendix G). b. Impacts and Mitigation Measures. Threshold 1 Would the project cause a substantial adverse change in the significance of a historic resource as defined in §15064.5? Impact CR-1 The project would result in the relocation, demolition, and removal of structures on the San Luis Ranch property which are individually identified as historic resources. In addition, the project would eliminate the San Luis Ranch Complex, which is eligible for listing as a historic resource. Relocation, demolition, and/or removal of these historic resources would permanently alter the historic context of the project site and on-site CHC 1-33 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-21 structures. This impact would be Class I, significant and unavoidable. As described in Section 4.5.1(d), the San Luis Ranch property, which includes the San Luis Ranch Complex, is eligible for listing as a City landmark, and is eligible for listing in the CRHR under Criterion 1 (association with early agricultural development in San Luis Obispo) and Criterion 3 (distinctive characteristics of early 20th century vernacular agricultural architecture). The characteristics and history of the San Luis Ranch property make it eligible for designation as a City of San Luis Obispo landmark property under Criterion B.2 (event) or B.3 (context). In addition, the main residence and the main barn that are within the San Luis Ranch Complex are individually eligible for listing as City landmarks, and are eligible for listing under CRHR Criterion 3 (distinctive characteristics of early 20th century vernacular agricultural and Craftsman architecture). In addition, the characteristics and history of the main residence and main barn make these structures eligible for designation as City landmark properties under Criterion A.1 (style). As such, the San Luis Ranch Complex, as well as the individual main residence and main barn structures are considered historic resources under CEQA. The project includes the adaptive reuse and relocation of the existing main residence and the former spectators’ barn/viewing stand to new locations on the site within the Agricultural Heritage and Learning Center. The project would also result in the demolition or off-site relocation of the remaining building and structures included in the San Luis Ranch Complex, including the historic main barn. Salvageable materials from the main barn are proposed to be reused to the greatest extent possible in the construction of a new barn in the project’s proposed Agricultural Heritage and Learning Center. The main residence and former spectators’ barn/viewing stand are proposed to be restored and adaptively reused following the Secretary of the Interior’s Standards. These proposed actions of the project would be subject to the requirements of the City Municipal Code Sections 14.01.100 and 14.01.110, which include requirements for the demolition and relocation of structures listed in the inventory of historic resources. Although the project site is not currently listed by the City as a historic resource because the project site is currently outside of the City limit, the project applicant seeks annexation by the City. Therefore, with annexation of the project site into the City, Municipal Code Sections 14.01.100 and 14.01.110 would apply to removal of the San Luis Ranch Complex and relocation of the main residence and spectators’ barn/viewing stand structure. Mitigative Components of the Specific Plan and Impact Conclusion. The San Luis Ranch Specific Plan proposes programs and policies intended to reduce impacts to historical resources to the maximum extent practicable. Specific Plan Policy 2.5 states that the Specific plan would “Protect associated structures such as the Dalidio Home, Laguna Race Track viewing stand, barn, and water tower.” Specific Plan Program 2.5.1 would require evaluation of the historic structures on the site for the purposes of preservation and protective reuse. The Specific Plan proposes relocation of the main residence and spectators’ barn/viewing stand to the Agricultural Heritage and Learning Center area for permanent preservation, and specifies that both structures would be subject to historic documentation by a qualified historian prior to relocation, including being photographed and recorded consistent with professional historical standards, and a qualified historic preservation architect would be consulted during relocation planning to ensure that significant historic materials and fabric are retained and reconstructed CHC 1-34 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-22 appropriately. The Specific Plan also specifies that the associated structures in the San Luis Ranch Complex would be photographed and recorded before they are removed from the site. Removal of the San Luis Ranch Complex and relocation, demolition, and/or removal of the historic main residence and main barn as part of the project would result in adverse changes to individually identified historic structures as well as the historic context of the San Luis Ranch property, which is collectively identified as historically significant. Additionally, demolition of the historic main barn, which is part of the San Luis Ranch Complex, would conflict with Conservation and Open Space Element Policy 3.3.1, Historic Preservation, which states that significant historic and architectural resources should be identified, preserved, and rehabilitated, as well as Conservation and Open Space Element Policy 3.3.2, Demolitions, which prohibits demolition or substantial changes in outward appearance of historically or architecturally significant buildings, unless doing so is necessary to remove a threat to health and safety and other means to eliminate or reduce the threat to acceptable levels are infeasible. For these reasons, the project would result in a potentially significant impact to historic resources and mitigation would be required. Mitigation Measures. The following mitigation measures would reduce project impacts on historical resources to the maximum extent practicable. CR-1(a) Historical Structure Relocation and Reconstruction Plan. In order to implement Specific Plan Policy 2.5, a relocation and reconstruction plan for the former spectator’s barn/viewing stand and main residence shall be developed by a qualified historic architect. The plan shall include a structural/architectural report documenting existing integrity and conditions and include detailed treatment methods and measures to ensure that historic integrity is retained and that all identified character defining features will be preserved. CR-1(b) Archival Documentation of Historic Buildings. The applicant shall provide archival documentation of the San Luis Ranch Complex in as- built and as-found condition in the form of a Historic American Building Survey (HABS) Level II documentation. The documentation shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990), and shall include large-format photographic recordation, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). The original archival-quality documentation shall be offered as donated material to the History Center of San Luis Obispo County. Archival copies of the documentation shall also be submitted to the San Luis Obispo County Library. CR-1(c) Informational Display of Historic Resources. A retrospective interpretive display detailing the history of the San Luis Ranch Complex and the project site, its significance, and its important details CHC 1-35 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-23 and features shall be developed by the applicant. The information should be incorporated into a publicly-accessed building on the project site, such as the proposed Agricultural Heritage Facilities and Learning Center, or a publicly-accessed outdoor location. The display shall include images and details from the HABS documentation described in Mitigation Measure CR-1(b) and any collected research pertaining to the historic property. The content shall be prepared by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). Plan Requirements and Timing. The project applicant shall prepare the relocation and reconstruction plan for the main residence and the spectators’ barn/viewing stand to the satisfaction of the Community Development Director prior to the issuance of project grading permits. Project grading plans shall detail phasing and include sufficient detail to demonstrate the sequencing and completion of the relocation and reconstruction plan. The applicant shall complete archival documentation of the San Luis Ranch Complex prior to the removal and/or demolition of the structures on the project site to the satisfaction of the Community Development Director. The applicant shall develop and install an informational display of the site’s identified historical resources prior to opening of the Agricultural Heritage Facilities and Learning Center to the public. Monitoring. The City shall confirm completion of and approve the relocation and reconstruction plan and archival documentation. The City shall confirm submittal of the documentation to the History Center of San Luis Obispo County and the San Luis Obispo County Library. The City shall also review applicable plans for compliance with recommendations of the relocation and reconstruction plan and periodically inspect the site to ensure compliance. The information display shall be prepared in accordance with recommendations of a qualified historic consultant and shall be approved by the Community Development Director. Residual Impacts. Mitigation Measure CR-1(a) would ensure that the main residence and barn/viewing stand would retain their individual integrity and character defining features. Mitigation Measure CR-1(a) would mitigate impacts to this individually significant resource to the maximum extent feasible. In addition, Mitigation Measures CR-1(b) and CR-1(c) would reduce significant direct impacts to the remainder of the historically significant San Luis Ranch Complex, including the individually significant historic main barn, to the maximum extent feasible. However, the removal and/or demolition of the historically significant main barn and the relocation, demolition, and removal of other structures in the San Luis Ranch Complex would change the historic context of the San Luis Ranch property. Furthermore, mitigation would not avoid the removal of the main barn, despite the proposed reuse of salvageable materials from the CHC 1-36 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-24 structure to the greatest extent possible in the construction of a new barn in the project’s proposed Agricultural Heritage and Learning Center. Therefore, the potential impact to the San Luis Ranch Complex and the main barn individually would remain significant and unavoidable despite implementation of the required mitigation. Threshold 2 Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Threshold 4 Would the project disturb any human remains, including those interred outside of formal cemeteries? Impact CR-2 Identified archaeological resources on the project site are ineligible for listing in the CRHR and NRHP, and disturbance of these resources would not constitute a significant impact. However, the potential remains for the project to result in impacts to previously unidentified archaeological resources. Therefore, this impact would be Class II, significant but mitigable. As described in Section 4.5.1(d), one prehistoric archaeological site (SLR-S-01) has been identified and recorded on the project site. SLR-S-01 is highly disturbed by repeated plowing, planting, harvesting, and other activities associated with crop cultivation. Although subsurface artifacts are present, they are limited to disturbed sediments above 40 centimeters below the surface, and do not represent an intact deposit. Based on the finding of the Cultural Resources Study (Appendix G), it is likely that the subsurface component consists of artifacts that were previously located on the surface scatter and have been redeposited due to remixing of sediments caused by agricultural activities. SLR-S-01 is not directly associated with important events or any persons significant in our past and, due to the absence of an intact subsurface component and lack of specific, interpretable context, the site is unlikely to yield important information about prehistory or history. As such, SLR-S-01 is not significant under CRHR Criteria 1, 2, 3 or 4. Therefore, the site is ineligible for listing in the CRHR and NRHP and requires no further management consideration under CEQA or the NHPA. Two prehistoric isolated artifacts (SLR-I-01 and SLR-I-02) have also been identified and recorded on the project site. Under CEQA, the isolates are not eligible for listing in the CRHR. The information potential of isolates SLR-I-01 and SLR-I-02 and site SLR-S-01 has been exhausted by their recordation and analysis as part of the Cultural Resources Study. The surface of the project site has been previously disturbed by over 100 years of agricultural activities including planting, harvesting, and other activities associated with crop cultivation and thus the possibility of encountering undisturbed archaeological resources during construction is unlikely. However, prehistoric archaeological deposits could be preserved at depth beneath the project site. Construction of the project involves grading and excavation in areas that could contain subsurface archaeological remains. Unanticipated discovery of human remains during project excavation would require compliance with Health and Safety Code Section 7050.5 and PRC Sections 5097.94 and 5097.98. Compliance with Health and Safety Code Section 7050.5 and PRC Sections 5097.94 and 5097.98 would ensure that unanticipated discovery of human remains during project excavation would be addressed appropriately by the County Coroner and NAHC (if required), and would not constitute a significant impact. CHC 1-37 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-25 Mitigative Components of the Specific Plan and Impact Conclusion. The San Luis Ranch Specific Plan includes requirements intended to protect archaeological resources. Specific Plan Policy 3.5.4 requires a preliminary site survey for development within archaeologically sensitive areas. As described in Section 4.5.1(d), the Cultural Resources Study (Appendix G) includes an evaluation of known archaeological resources on the project site, and determined that these resources are not intact or otherwise archaeologically significant. However, excavation associated with the project grading plan would have the potential to encounter buried archaeological deposits. Therefore, mitigation is required to ensure that any discovered resources would be protected and curated if encountered during project construction. Mitigation Measures. The following measures would reduce potential impacts to archaeological resources to a less than significant level. CR-2(a) Retain a Qualified Principal Investigator. In accordance with Conservation and Open Space Policies 3.5.6 and 3.5.7, a qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology (hereafter qualified archaeologist), shall be retained to carry out all mitigation measures related to archaeological resources. Monitoring shall involve inspection of subsurface construction disturbance at or in the immediate vicinity of known sites, or at locations that may harbor buried resources that were not identified on the site surface. A Native American monitor shall also be present because the area is a culturally sensitive location. The monitor(s) shall be on-site on a full-time basis during earthmoving activities, including grading, trenching, vegetation removal, or other excavation activities. CR-2(b) Unanticipated Discovery of Archaeological Resources. In the event that archaeological resources are exposed during construction, all work shall be halted in the vicinity of the archaeological discovery until a qualified archaeologist can visit the site of discovery and assess the significance of the cultural resource. In the event that any artifact or an unusual amount of bone or shell is encountered during construction, work shall be immediately stopped and relocated to another area. The lead agency shall stop construction within 100 feet of the exposed resource until a qualified archaeologist/paleontologist can evaluate the find (see 36 CFR 800.11.1 and CCR, Title 14, Section 15064.5[f]). Examples of such cultural materials might include: ground stone tools such as mortars, bowls, pestles, and manos; chipped stone tools such as projectile points or choppers; flakes of stone not consistent with the immediate geology such as obsidian or fused shale; historic trash pits containing bottles and/or ceramics; or structural remains. If the resources are found to be significant, they must be avoided or will be mitigated consistent with State Historic Preservation Office (SHPO) Guidelines. CHC 1-38 Attachment 1 San Luis Ranch Project EIR Section 4.5 Cultural Resources City of San Luis Obispo 4.5-26 Plan Requirements and Timing. The project applicant shall retain a qualified principal investigator and Native American monitor prior to the issuance of grading permits. The requirement that construction work be stopped in the event of discovery of archaeological resources shall be included on construction plans prior to the issuance of grading permits. Monitoring. The City shall confirm the qualifications of and approve the applicant’s choice of a qualified principal investigator and Native American monitor. The City shall also inspect the site periodically during grading and demolition to ensure compliance with this measure. The City shall review construction plans and periodically inspect project construction to ensure compliance with this measure. Residual Impacts. Implementation of Mitigation Measures CR-2(a) and CR-2(b) would reduce impacts to archaeological resources to a less than significant level. c. Cumulative Impacts. Planned buildout of the City of San Luis Obispo under the General Plan, including buildout of previously approved (Margarita and Orcutt) or proposed (San Luis Ranch, Avila Ranch, Madonna) specific plans, would cumulatively increase the potential for adverse effects on historic and archaeological resources in the City. The project would incrementally contribute to this cumulative effect. Impacts to historic and archaeological resources are generally site-specific. Accordingly, as required under applicable laws and regulations, potential impacts associated with cumulative developments would be addressed on a case-by-case basis. As discussed in Section 4.5.2, the San Luis Ranch Specific Plan, as well as other approved and proposed plans in the City, is required to comply with existing General Plan Conservation and Open Space Element Policies 3.3.1, 3.3.2, 3.3.3, 3.5.1, 3.5.2, 3.5.3, 3.5.4, 3.5.5, 3.5.6, 3.5.7, and 3.6.3, which address the protection of historical and archaeological resources within the City. As described in Impact CR-2, the project would not result in the loss of any significant archaeological resources and, therefore, would not contribute substantially to the cumulative loss of archaeological resources in the City. However, the project would result in a significant and unavoidable impact associated with the removal of individually historic structures that are part of the historically significant San Luis Ranch Complex. As such, the project would contribute to the cumulative loss of historic resources in the City. Therefore, the project would also result in a Class I, significant and unavoidable, cumulative impact to historical resources.

(Rincon) was retained by the City of San Luis Obispo to conduct a cultural resources study in support of the preparation of an Environmental Impact Report (EIR) for the San Luis Ranch Project (project). The project site is approximately 131-acres of land on in unincorporated San Luis Obispo County, surrounded by the corporate boundary of San Luis Obispo. This study has been prepared to provide the required analysis for the project in conformance with the California Environmental Quality Act (CEQA). This cultural resources study includes background environmental and cultural context of the project site, Native American scoping, background research, an intensive pedestrian survey of the project site, archaeological testing, evaluation of archaeological and built environment resources, and preparation of this report. All work was prepared in accordance with the CEQA, Public Resources Code Section 5024.1, Section 15064.5 of the Guidelines; and Sections 21083.2 and 21084.1 of the Statutes of CEQA (Governor’s Office of Planning and Research 1998); and in accordance with regulations set forth in the city’s Historic Preservation Ordinance. The Native American Heritage Commission conducted a Sacred Lands File search with negative results on January 27, 2016. Rincon conducted Native American scoping, which did not identify any identify any specific resources important to the consulted groups within the project site. However, several contacts noted that the area is sensitive. The review of cultural resource records at the California Historical Resources Information System Central Coast Information Center identified one previously recorded cultural resource within the project site: the Dalidio Ranch/San Luis Ranch complex (P-40-041000), a complex of historic buildings. Rincon identified and recorded three archaeological resources during the pedestrian survey: two prehistoric isolated artifacts (P-40-038327 and P-40-038328) and one prehistoric archaeological site (CA-SLO-2825). Archaeological site CA-SLO-2825 comprises a prehistoric surface artifact scatter with a shallow subsurface component and is located in the western portion of the project site near the modern alignment of Prefumo Creek. The discovery of this site prompted a Phase II archaeological investigation to determine the site boundaries and to assess if this CA-SLO-2825 is eligible for listing in the California Register of Historical Resources and National Register of Historic Places (NRHP). Site CA-SLO-2825 is recommended ineligible for listing in the CRHR and NRHP and thus requires no further management consideration under CEQA. Due to the assemblage’s lack of association with specific people or discrete events and because the recovered artifacts have little potential to contribute to future research, Rincon recommends no further work for the recovered items, and we do not recommend permanent curation. In lieu of curation, Rincon recommends donation of collected artifacts to a local Native American Tribe. Rincon recommends implementation of the following measures to reduce potential impacts to unanticipated archaeological resources: retain a qualified archaeologist to carry out all mitigation measures related to archaeological and historical resources; stop work within immediate vicinity of the find if unanticipated cultural deposits or human remains are discovered; and comply with existing regulations. The resource record for one previously recorded built environment resource complex, the Dalidio Ranch, was updated and the ranch reevaluated as part of the project. The ranch CHC 1-47 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 6 complex includes three single-family residences, a garage/shed, a smaller shed, a barn, a large equipment storage building, a warehouse, and the former spectator’s barn (viewing stand) which was converted to farm use. The Dalidio Ranch appears eligible for listing in the California Register of Historical Resources as a property, under Criteria 1 and 3. It also appears eligible for designation as a City of San Luis Obispo landmark property (B.2 and B.3). Residence No. 1 and the main barn also appear individually eligible for listing in the CRHR and as City of San Luis Obispo landmark properties for their construction and design (Criteria 3 and A.1). The project would result in the relocation and adaptive reuse of two of the buildings contributing to the historic district (the main residence and former spectators’ barn/ viewing stand), and the demolition or off-site relocation of the remainder of the contributing buildings and structures that comprise the Dalidio Ranch complex. Therefore, the proposed project would result in a substantial adverse change to a historical resource. Although not capable of reducing impacts to below the level of significance, three mitigation measures were identified that would reduce project impacts related to the demolition to the maximum extent practicable: 1) A relocation plan should be developed and implemented for the main Craftsman residence (residence No.1) and former spectators’ barn/viewing stand. The comprehensive relocation plan should include a structural/architectural condition and feasibility assessment to provide the necessary existing conditions data required to substantiate the relocation. If relocation is found feasible, the plan should identify a suitable relocation site that is compatible with the existing setting of the property; such as the proposed project’s agricultural center. The plan must also include detailed measures that demonstrate that the buildings will retain their historic significance following their relocation. Completion of this mitigation measure shall be monitored and enforced by the City of San Luis Obispo. 2) Prior to issuance of demolition permits, the lead agency shall ensure that documentation of the buildings and structures proposed for relocation and/or demolition is completed that follows the general guidelines of Historic American Building Survey (HABS) Level II documentation. The documentation shall include large-format photographic recordation, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). 3) Impacts related to the loss of the Dalidio Ranch complex shall be reduced through the development of a retrospective interpretive display detailing the history of the project site, its significance, and its important details and features. The information can be incorporated into a publicly-accessed building on the project site or a publicly-accessed outdoor location. The display shall include images and details from the HABS documentation and any collected research pertaining to the historic property. Implementation of these three historical mitigation measures would reduce significant direct and cumulative impacts to the historical resource planned for demolition to the maximum extent feasible. Nevertheless, the relocation, demolition and removal of the buildings and structures comprising the Dalidio Ranch complex would eliminate the historic district and would remain a significant adverse impact.

CHC 1-49 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 8 1.0 INTRODUCTION Rincon Consultants, Inc. (Rincon) was retained by the City of San Luis Obispo to conduct a cultural resources study in support of the preparation of an Environmental Impact Report (EIR) for the San Luis Ranch Project (project). The project consists of a Specific Plan, General Plan Amendment, and development plan for the 131-acre project site, including annexation of the site into the City of San Luis Obispo. The project includes a mixture of residential, commercial, office, and hotel uses, with a portion of the site preserved for agriculture and open space uses. The project requires an environmental review under the California Environmental Quality Act (CEQA), and has thus been prepared in accordance with CEQA statutes and guidelines. The City of San Luis Obispo is the lead agency for CEQA review of the project. This cultural resources study includes an overview of the regulatory setting for the project, background environmental and cultural context of the project site, Native American scoping, background research, a description of the methods employed in this study, the results of the intensive pedestrian survey of the project site, a summary of Phase II archaeological testing and evaluation, a built environment evaluation, and preparation of this report. 1.1 PROJECT SITE The site is located in unincorporated San Luis Obispo County, completely surrounded by the corporate boundary of San Luis Obispo; it is also within the city’s Sphere of Influence. The project site is generally bounded by residential uses and Madonna Road to the west, commercial uses and Dalidio Drive to the north, United States Highway 101 (U.S. 101) to the east and the San Luis Obispo City Farm to the south (Figures 1 and 2). Prefumo Creek is located south of the site. The site is identified by assessor’s parcel number (APN) 067-121-022. The project proposes to provide or pay fair share fees for such public improvements as a widening of Madonna Road along project frontage, additions to Dalidio Drive/Prado Road, an extension of Froom Ranch Way across Prefumo Creek in the southwest corner of the site, and to contribute in fair share towards an overpass or interchange connection for Prado Road. The proposed extension of Froom Ranch Way was included as part of the current investigation.

San Luis Ranch ProjectCultural Resources Survey and Evaluation ±0 500250 Feet Project Boundary CHC 1-52 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 11 1.2 PROJECT DESCRIPTION The San Luis Ranch Project (project) consists of a Specific Plan, General Plan Amendment, and development plan for the 131-acre project site, including annexation of the site into the City of San Luis Obispo. The project is intended to be consistent with the development parameters described in the City’s Land Use and Circulation Element (adopted in December of 2014). The project includes a mixture of residential, commercial, office, and hotel uses, with a portion of the site preserved for agriculture and open space uses. The Dalidio Ranch complex, which includes a farm house and outbuildings, is located in the western portion of the property adjacent to Madonna Road. Project development would result in the adaptive reuse and relocation of the existing main residence and the former spectators’ barn/viewing stand to new locations on the site within the Agricultural Heritage Center, and the demolition or off-site relocation of the remaining buildings and structures. Salvageable materials from the main barn are proposed to be reused to the greatest extent possible in the construction of a new barn in the project’s Agricultural Heritage Center. The main residence and former spectators’ barn/viewing stand are proposed to be restored and adaptively reused following the Secretary of the Interior’s Standards. The project includes a mix of 580 low-medium, medium, and high-density residences that would be located primarily on the northwestern and central portion of the project site. Housing would range from detached single-family units to attached multi-family dwellings. The neighborhoods would be connected with a local street and trail system, and would contain recreational areas. The project includes 150,000 square feet of commercial development, 100,000 square feet of office development, and a 200 room hotel. The commercial and hotel components are proposed on the area of land fronting the extended Prado Road/Dalidio Drive and Froom Ranch Way. Commercial uses proposed for the project may include retail anchors, neighborhood retail, restaurants, offices, and a hotel. The project would preserve approximately 52.7 acres of the site in agriculture adjacent to the San Luis Obispo City Farm. The project would also preserve approximately 7.6 acres of the site in open space. Collectively, this would comprise 46.6 percent of the net site acreage (when major roadways and right of way for the future Prado Road interchange are discounted). As part of the proposed agricultural uses, the project also includes an Agricultural Heritage Facilities & Learning Center, which would be intended as an educational center for local residents and an agricultural tourism destination. The farmland adjacent to U.S. 101 would be preserved in perpetuity for its agricultural and view shed value. The Specific Plan includes a transit center that would provide direct transit access between the project site and downtown San Luis Obispo. The location of the proposed transit center would be coordinated with SLO Transit and the Regional Transit Authority upon submittal of individual project plans. The project site is relatively level, with a gentle slope to the south and southwest. The medium and high density residential areas would be graded using standard methods. Through the placement of fill, the proposed single-family and commercial areas would be graded such that, CHC 1-53 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 12 at a minimum, all structures would be removed from the flood plain. Grading in the Agricultural Heritage Facilities & Learning Center area would include the placement of fill to protect the proposed structures from flooding. Grading of agricultural areas would include the preservation of high quality topsoil through stockpiling and redistribution in order to enhance agricultural viability. The project would be constructed in six phases. Phases 1, 2, and 3 would consist of residential buildout and construction are planned to begin in 2017 and be completed in 2020. Phases 4 and 5 would consist of office and hotel buildout. Construction is expected to begin in 2017 and be completed in 2023. Phase 6 would consist of commercial buildout and is planned to begin in 2018 and be completed in 2023. 1.3 PERSONNEL Cultural Resources Principal Investigator Christopher Duran, M.A., RPA, managed this cultural resources study and served as the archaeological principal investigator for the study.

CHC 1-54 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 13 2.0 REGULATORY SETTING This section discusses the laws, ordinances, and codes governing cultural resources, which must be adhered to before and during implementation of the proposed project. The project is subject to state and local laws, ordinances, and codes, including CEQA, the Historic Preservation Ordinance of the City of San Luis Obispo, and the San Luis Obispo Municipal Code. The project does not have a federal nexus and, therefore, compliance with reference to the NHPA and other federal laws is provided here for informational purposes only. 2.1 FEDERAL Projects that involve federal funding or permitting (i.e., have a federal nexus) must comply with the provisions of the National Historic Preservation Act of 1966 (NHPA), as amended (16 United States Code [U.S.C.] 470f). Cultural resources are considered during federal undertakings chiefly under Section 106 of the NHPA through one of its implementing regulations, 36 Code of Federal Regulations (CFR) 800 (Protection of Historic Properties), as well as the National Environmental Policy Act (NEPA). Properties of traditional religious and cultural importance to Native Americans are considered under Section 101(d)(6)(A) of the NHPA. Other relevant federal laws include the Archaeological Data Preservation Act of 1974, American Indian Religious Freedom Act of 1978, Archaeological Resources Protection Act of 1979, and Native American Graves Protection and Repatriation Act of 1989. 2.1.1 National Register of Historic Places The National Register of Historic Places (NRHP) was established by the National Historic Preservation Act (NHPA) of 1966 as “an authoritative guide to be used by Federal, State, and local governments, private groups and citizens to identify the Nation’s cultural resources and to indicate what properties should be considered for protection from destruction or impairment" (CFR 36 CFR 60.2). The NRHP recognizes properties that are significant at the national, state, and local levels. To be eligible for listing in the NRHP, a resource must be significant in American history, architecture, archaeology, engineering, or culture. Districts, sites, buildings, structures, and objects of potential significance must also possess integrity of location, design, setting, materials, workmanship, feeling, and association. A property is eligible for the NRHP if it is significant under one or more of the following criteria: Criterion A: It is associated with events that have made a significant contribution to the broad patterns of our history; Criterion B: It is associated with the lives of persons who are significant in our past; Criterion C: It embodies the distinctive characteristics of a type, period, or method of construction, or represents the work of a master, or possesses high artistic values, or represents a significant and distinguishable entity whose components may lack individual distinction; and/or Criterion D: It has yielded, or may be likely to yield, information important in prehistory or history. CHC 1-55 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 14 2.2 STATE A public agency must comply with CEQA when it undertakes an activity defined by CEQA as a “project.” A project is an activity that, when undertaken by a public agency or private party, must receive discretionary approval. The project requires discretionary local and county permits, obtained from public agencies. Therefore, the undertaking is considered a project and is subject to CEQA. 2.2.1 California Environmental Quality Act CEQA requires a lead agency to determine whether a project may have a significant effect on historical resources (Public Resources Code [PRC], Section 21084.1). A historical resource is a resource listed, or determined to be eligible for listing, in the California Register of Historical Resources (CRHR); a resource included in a local register of historical resources; or any object, building, structure, site, area, place, record, or manuscript that a lead agency determines to be historically significant (State CEQA Guidelines, Section 15064.5[a][1-3]). A resource shall be considered historically significant if it: 1) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; 2) Is associated with the lives of persons important in our past; 3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or 4) Has yielded, or may be likely to yield, information important in prehistory or history. In addition, if a project can be demonstrated to cause damage to a unique archaeological resource, the lead agency may require reasonable efforts to permit any or all of these resources to be preserved in place or left in an undisturbed state. To the extent that resources cannot be left undisturbed, mitigation measures are required (PRC, Section 21083.2[a], [b], and [c]). PRC, Section 21083.2(g) defines a unique archaeological resource as an artifact, object, or site about which it can be clearly demonstrated that, without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria: 1) Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information; 2) Has a special and particular quality such as being the oldest of its type or the best available example of its type; or 3) Is directly associated with a scientifically recognized important prehistoric or historic event or person. 50 Year Threshold for the CRHR According to CEQA, all buildings constructed over 50 years ago and that possess architectural or historical significance may be considered potential historic resources. Most resources must meet the 50-year threshold for historic significance; however, resources less than 50 years in age CHC 1-56 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 15 may be eligible for listing on the CRHR if it can be demonstrated that sufficient time has passed to understand their historical importance. 2.3 CITY OF SAN LUIS OBISPO The project is also subject to local measures, including the Historic Preservation Ordinance of the City of San Luis Obispo and the San Luis Obispo Municipal Code. These regulations are discussed below. 2.3.1 Historic Preservation Ordinance In 2010, the City of San Luis Obispo passed a Historic Preservation Ordinance to identify and protect important historic resources within the city (City of San Luis Obispo 2010). When determining if a property should be designated as a listed Historic or Cultural Resource, the Cultural Heritage Commission and City Council are to consider this ordinance and SHPO standards. To be eligible for designation, the resource shall exhibit a high level of historic integrity, be at least 50 years old (less than 50 if it can be demonstrated that enough time has passed to understand its historical importance) and satisfy at least one of the following criteria: A. Architectural Criteria: Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master, or possesses high artistic values. (1) Style: Describes the form of a building, such as size, structural shape and details within that form (e.g. arrangement of windows and doors, ornamentation, etc.). Building style will be evaluated as a measure of: a. The relative purity of a traditional style; b. Rarity of existence at any time in the locale; and/or current rarity although the structure reflects a once popular style; c. Traditional, vernacular and/or eclectic influences that represent a particular social milieu and period of the community; and/or the uniqueness of hybrid styles and how these styles are put together. (2) Design: Describes the architectural concept of a structure and the quality of artistic merit and craftsmanship of the individual parts. Reflects how well a particular style or combination of styles are expressed through compatibility and detailing of elements. Also, suggests degree to which the designer (e.g., carpenter-builder) accurately interpreted and conveyed the style(s). Building design will be evaluated as a measure of: a. Notable attractiveness with aesthetic appeal because of its artistic merit, details and craftsmanship (even if not necessarily unique); b. An expression of interesting details and eclecticism among carpenter- builders, although the craftsmanship and artistic quality may not be superior. (3) Architect: Describes the professional (an individual or firm) directly responsible for the building design and plans of the structure. The architect will be evaluated as a reference to: CHC 1-57 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 16 a. A notable architect (e.g., Wright, Morgan), including architects who made significant contributions to the state or region, or an architect whose work influenced development of the city, state or nation. b. An architect who, in terms of craftsmanship, made significant contributions to San Luis Obispo (e.g., Abrahams who, according to local sources, designed the house at 810 Osos - Frank Avila’s father’s home - built between 1927 – 30). B. Historic Criteria: (1) History – Person: Associated with the lives of persons important to local, California, or national history. Historic person will be evaluated as a measure of the degree to which a person or group was: a. Significant to the community as a public leader (e.g., mayor, congress member, etc.) or for his or her fame and outstanding recognition - locally, regionally, or nationally. b. Significant to the community as a public servant or person who made early, unique, or outstanding contributions to the community, important local affairs or institutions (e.g., council members, educators, medical professionals, clergymen, railroad officials). (2) History – Event: Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. Historic event will be evaluated as a measure of: a. A landmark, famous, or first-of-its-kind event for the city - regardless of whether the impact of the event spread beyond the city. b. A relatively unique, important or interesting contribution to the city (e.g., the Ah Louis Store as the center for Chinese-American cultural activities in early San Luis Obispo history). (3) History-Context: Associated with and also a prime illustration of predominant patterns of political, social, economic, cultural, medical, educational, governmental, military, industrial, or religious history. Historic context will be evaluated as a measure of the degree to which it reflects: a. Early, first, or major patterns of local history, regardless of whether the historic effects go beyond the city level, that are intimately connected with the building (e.g., County Museum). b. Secondary patterns of local history, but closely associated with the building (e.g., Park Hotel). C. Integrity: Authenticity of an historical resource’s physical identity evidenced by the survival of characteristics that existed during the resource’s period of significance. Integrity will be evaluated by a measure of: (1) Whether or not a structure occupies its original site and/or whether or not the original foundation has been changed, if known. (2) The degree to which the structure has maintained enough of its historic character or appearance to be recognizable as an historic resource and to convey the reason(s) for its significance. CHC 1-58 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 17 (3) The degree to which the resource has retained its design, setting, materials, workmanship, feeling and association. 2.3.2 Municipal Code In addition to the City of San Luis Obispo’s requirements to designate a Historic or Cultural Resource, the city’s municipal code contains specific requirements for the demolition and relocation of structures listed in the inventory of historic resources. These requirements are stated in Municipal Code sections 14.01.100 and 14.01.110. Although the project site is not currently listed by the city as a historic resource, the project applicant seeks annexation by the city; thus, the project would be subject to these requirements in the future. The City of San Luis Obispo municipal code states that the Cultural Heritage Committee (CHC) shall review and make recommendations to the City Council regarding demolition applications for structures listed in the inventory of historic resources. An application for demolition of a listed historic resource shall be approved only if the proposed demolition is found consistent with the general plan and 1) the historic resource is a hazard to public health of safety, and repair or stabilization is not structurally feasible; or 2) denial of the application will constitute an economic hardship as described in section 14.01.100(J)(1-3) of the municipal code. Additional procedures regarding the timing of the demolition, documentation and acknowledgment of the historic resource are also delineated. Likewise, the relocation of a structure listed on the inventory of historic resources is subject to review by the CHC and Architectural Review Commission (ARC). Relocation shall be permitted only when relocation is consistent with the goals and policies of the general plan, any applicable area or specific plans, and the Historic Preservation Program Guidelines, as well as additional criteria defined in Municipal Code Section 14.01.110(B)(1-6). The timing, plan, procedures and documentation are also delineated. CHC 1-59 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 18 3.0 SETTING 3.1 ENVIRONMENTAL SETTING The project site is located in unincorporated San Luis Obispo County, completely surrounded by the corporate boundary of San Luis Obispo at an approximate elevation of 36-42 meters (118- 138 feet) above mean sea level. The project site is within San Luis Valley northeast of the Irish Hills and southwest of the southern extent of the Santa Lucia Mountain Range. The project site is currently used for agricultural purposes, primarily as cultivated row crops and has been farmed for approximately 100 years (Martin 2015; Bertrando 1999a). Dry and partially irrigated field crops, including garbanzo beans, dry beans, cabbage and lettuce, have been produced on the property. A single broad swale bisects the western portion of the property. This system drains toward Prefumo Creek at the project site’s southern edge. Prefumo Creek is lined with multiple rows of mature blue gum Eucalyptus trees and other vegetation, including arroyo willow, red willow, sycamore, and cottonwood trees; mulefat, poison oak, and toyon; and wild oats, foxtail chess, and fescue. 3.2 PREHISTORY The project site lies in what is generally described as the Central Coast archaeological region, one of eight organizational divisions of the state (Jones and Klar 2007, Moratto 1984:Fig. 1). The Central Coast archaeological region extends from Monterey Bay to Morro Bay, and includes the County of San Luis Obispo. Following Jones and Klar (2007:137), the prehistoric cultural chronology for the Central Coast can be generally divided into six periods: Paleo-Indian (ca. 10,000–6,000 B.C.), Milling Stone (6,000-3,000 B.C.), Early and Early-Middle Transition (3,000- 600 B.C.), Middle (600 B.C.- A.D. 1000), Middle-Late Transition (A.D. 1000-A.D. 1250), and Late (A.D. 1250-historic contact [ca. A.D. 1769]). Several chronological sequences have been devised to understand cultural changes along the Central Coast from the Millingstone Period to contact. Jones (1993) and Jones and Waugh (1995) presented a Central Coast sequence that integrated data from archaeological studies conducted since the 1980s. Three periods, including the Early, Middle, and Late periods, are presented in their prehistoric sequence subsequent to the Millingstone Period. More recently, Jones and Ferneau (2002:213) updated the sequence following the Millingstone Period as follows: Early, Early-Middle Transition, Middle, Middle-Late Transition, and Late periods. The archaeology of the Central Coast subsequent to the Millingstone Period is distinct from that of the Bay Area and Central Valley. The region has more in common with the Santa Barbara Channel area during the Middle and Middle-Late Transition periods, but few similarities during the Late period (Jones & Ferneau 2002:213). 3.2.1 Paleo-Indian Period (ca. 10,000 – 6000 B.C.) When Wallace (1955, 1978) developed the Early Man horizon in the 1950s (referred to herein as the Paleo-Indian Period), little evidence of human presence was known for the southern California coast prior to 6000 B.C. Archaeological work in the intervening years has identified a number of older sites, including coastal and Channel Islands sites (e.g., Erlandson 1991; Johnson et al. 2002; Moratto 1984). CHC 1-60 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 19 The earliest accepted dates for human occupation along the Central Coast were recovered from archaeological sites on two of the Northern Channel Islands, located off the southern coast of Santa Barbara County. On San Miguel Island, archaeological evidence from the Daisy Cave site establishes the presence of people in this area approximately 10,000 years ago (Erlandson 1991:105). On Santa Rosa Island, human remains have been dated from the Arlington Springs site to approximately 13,000 years ago (Johnson et al. 2002). In San Luis Obispo County, archaeological sites CA-SLO-1764 (Lebow et al. 2001), Cross Creek (CA-SLO-1797; Fitzgerald 2000), and CA-SLO-832 (Jones et al. 2001) yielded radiocarbon dates from approximately 9,000 years ago (Jones and Ferneau 2002). Recent data from Paleo-Indian sites in southern California indicate that the economy was a diverse mixture of hunting and gathering, with a major emphasis on aquatic resources in many coastal areas (e.g., Jones and Ferneau 2002). Although few Clovis-like or Folsom-like fluted projectile points have been found in southern California (e.g., Erlandson et al. 1987), the emphasis on hunting may have been greater during the Paleo-Indian period than during later periods. A fluted projectile point fragment was recovered from site CA-SBA-1951 on the Santa Barbara Channel coastal plain (Erlandson 1994:44; Erlandson et al. 1987). Another fluted projectile point was reportedly found on the surface in Nipomo, San Luis Obispo County (Mills et al. 2005; Jones and Klar 2007). Large side-notched projectile points of the Central Coast Stemmed series in this area date to as early as 8,000 years ago (Justice 2002). Points of this type have been recovered along the Central Coast from sites such as Diablo Canyon (CA-SLO-2; Greenwood 1972), Cross Creek (CA-SLO- 1797; Fitzgerald 2000), Little Pico Creek (CA-SLO-175; Jones and Waugh 1995), and the Honda Beach site (CA-SBA-530; Glassow 1997), among others. The Metcalf site (CA-SCL-178; Hildebrandt 1983), in southern Santa Clara Valley, yielded two large side-notched projectile points associated with charcoal dates ranging from 9,960 – 8,500 years ago. 3.2.2 Milling Stone Horizon (6000 – 3000 B.C.) The Milling Stone Horizon, as described by Wallace (1955, 1978), is characterized by an ecological adaptation to collecting plant resources, such as seeds and nuts, suggested by the appearance and abundance of well-made milling (ground stone) implements. The dominance of milling implements is generally associated with the horizontal motion of grinding small seeds and nuts and lends to the name Milling Stone Horizon. Rogers (1929) originally identified the Milling Stone Horizon along the Santa Barbara Channel in 1929. Excavations at the Tank Site (CA-LAN-1) in Topanga Canyon from 1947 to 1948 (Treganza and Bierman 1958) confirmed the presence of a significant number of milling implements that correspond with the Milling Stone Horizon identified by Rogers in 1929. Wallace (1955, 1978) further defined the Horizon, which was recognized on the Central Coast by Greenwood (1972). The Cross Creek site (CA-SLO-1797) is a Milling Stone occupation site in San Luis Obispo County that returned radiocarbon dates ranging between 9,500 – 4,700 years ago. This site represents one of the oldest expressions of the pattern (Jones et al. 2007; Fitzgerald 2000:58). Wallace (1955, 1978) and Warren (1968) identify ground stone implements including milling stones (e.g., metates, milling slabs, or mortars) and hand stones (e.g., manos, mullers, or CHC 1-61 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 20 pestles). Milling stones occur in high frequencies for the first time in the archaeological record of the Central Coast region, and become even more prevalent near the end of the Milling Stone Horizon. Flaked stone assemblages, which include crude core and cobble-core tools, flake tools, large side-notched projectile points, and pitted stones (Jones et al. 2007), and shell middens in coastal sites suggest that people during this period practiced a mixed food procurement strategy. Faunal remains identified at Milling Stone sites point to broad-spectrum hunting and gathering of shellfish, fish, birds, and mammals, though large faunal assemblages are uncommon. This mixed food procurement strategy demonstrates adaptation to regional and local environments. Along the Central Coast, Milling Stone Horizon sites are most common on terraces and knolls, typically set back from the current coastline (Erlandson 1994:46). However, 42 sites have been identified in various settings, including rocky coasts, estuaries, and nearshore interior valleys (Jones and Klar 2007). The larger sites usually contain extensive midden deposits, possible subterranean house pits, and cemeteries. Most of these sites probably reflect intermittent use over many years of local cultural habitation and resource exploitation. 3.2.3 Early Period and Early-Middle Transition Period (3000 B.C. – 600 B.C.) Although Jones and Ferneau (2002:213) have distinguished an Early-Middle Transition period, it is not well defined and is difficult to observe. Thus, the transition phase is included in the following discussion of the sites and characteristics recognized for the Early Period in the Central Coast region. A high frequency of shoreline midden deposits has been identified in the Central Coast region dating to the Early Period. This suggests that population numbers increased from the Milling Stone Horizon to the Early Period along the Central Coast (Jones 1995; Jones and Waugh 1995, 1997). Archaeological sites dating to the Early Period include CA-SLO-165 in Estero Bay, and CA-MNT-73, CA-MNT-108, and CA-MNT-1228 in Monterey Bay. The material culture recovered from Early Period sites within the Central Coast region provides evidence for continued exploitation of inland plant and coastal marine resources. Artifacts include milling slabs and handstones, as well as mortars and pestles, which were used for processing a variety of plant resources. Bipointed bone gorge hooks were used for fishing. Assemblages also include a suite of Olivella beads, bone tools, and pendants made from talc schist. Square abalone shell (Haliotis spp.) beads have been found in Monterey Bay (Jones and Waugh 1997:122). Shell beads and obsidian are hallmarks of the trade and exchange networks of the central and southern California coasts. The archaeological record indicates that there was a substantial increase in the abundance of obsidian at Early Period sites in the Monterey Bay and San Luis Obispo areas (Jones and Waugh 1997:124–126). Obsidian trade continued to increase during the following Middle period. Flaked stone artifact assemblages from Early Period sites include Central Coast Stemmed Series and side-notched projectile points. Square-stemmed and side- notched points were recovered from deposits at Willow Creek (CA-MNT-282) in Big Sur and Little Pico II (CA-SLO-175) on the San Luis Obispo coast (Jones and Ferneau 2002). This projectile point style trend, first identified by David Banks Rogers in 1929, was confirmed by Greenwood (1972) at Diablo Canyon. The projectile point trend has become apparent at CHC 1-62 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 21 numerous sites throughout the Central Coast. In many cases, manifestations of this trend are associated with the establishment of new settlements (Jones et al. 2007). 3.2.4 Middle Period (600 B.C. – A.D. 1000) A pronounced trend toward greater adaptation to regional or local resources occurred during the Middle period. The remains of fish, land mammals, and sea mammals are increasingly abundant and diverse in archaeological deposits along the coast. Flaked stone tools used for hunting and processing—such as large side-notched, stemmed, lanceolate or leaf-shaped projectile points, large knives, edge modified flakes, and drill-like implements—occurred in archaeological deposits in higher frequencies and are more morphologically diversified during the Middle Period. Bone tools, including awls, are more numerous than in the preceding period, and the use of asphaltum adhesive became common. Shell fishhooks also became part of the toolkit during this period. Complex maritime technology, such as circular fish hooks, compound bone fish hooks, and the tule reed or balsa raft, also proliferated during this period. Notable technological introductions include circular shell fishhooks that date from between 1000 and 500 B.C. (Jones and Klar 2005:466). Compound bone fishhooks appear in deposits dating between A.D. 300 and 900 (Arnold 1995; Jones and Klar 2005:466; Kennett 1998:357; King 1990:87–88). Populations continued to follow a seasonal settlement pattern until the end of the Middle Period. Large, permanently occupied settlements, particularly in coastal areas, appear to have been the norm by the end of the Middle Period (Kennett 1998). 3.2.5 Middle-Late Transition Period (A.D. 1000 - 1250) The Middle-Late Transition period is marked by relative instability and change, with major changes in diet, settlement patterns, and interregional exchange. The relatively ubiquitous Middle period shell midden sites found along the Central Coast were abandoned by the end of the Middle-Late Transition period, so most Transition period and Late period sites were first occupied during those periods (Jones and Ferneau 2002:213, 219). Site CA-SLO-239 has been tentatively dated to the Middle-Late Transition Period, and contains the only residential feature, a circular house floor, dating to this time period (Jones et al. 2007; Mikkelsen et al. 2000). During the Middle to Late Transition period, projectile points diagnostic of both the Middle and Late periods are found within the Central Coast region (Jones and Ferneau 2002:217). These projectile points include large, contracting-stemmed types typical of the Middle Period, as well as small, leaf-shaped Late Period projectile points, which likely reflect the introduction of the bow and arrow. 3.2.6 Late Period (A.D. 1250 – Historic Contact) Late Period sites are distinguished by small, finely-worked projectile points and temporally diagnostic shell beads. Although shell beads were typical of coastal sites, trade brought many of these maritime artifacts to inland locations, especially during the latter part of the Late Period. Small, finely-worked projectile points are typically associated with bow and arrow technology, which is believed to have been introduced to the area by the Takic migration from the deserts into southern California. CHC 1-63 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 22 Common artifacts identified at Late Period sites include bifacial bead drills, bedrock mortars, hopper mortars, lipped and cupped Olivella shell beads, and steatite disk beads. The presence of beads and bead drills suggest that low-level bead production was widespread throughout the Central Coast region (Jones and Klar 2007). Unlike the large Middle period shell middens, Late Period sites are more frequently single- component deposits. There are also more inland sites, with fewer and less visible sites along the Pacific shore during the Late Period. The settlement pattern and dietary reconstructions indicate a lesser reliance on marine resources than observed for the Middle and Middle-Late Transition periods, as well as an increased preference for deer and rabbit (Jones 1995). An increase in the number of sites with bedrock mortar features that date to the Late Period suggests that nuts and seeds began to take on a more significant dietary role in Late Period populations. 3.3 ETHNOGRAPHIC OVERVIEW The project site was historically occupied by the Obispeño Chumash, so called after their historic period association with Mission San Luis Obispo de Tolosa (Gibson 1983; Kroeber 1925). The precise location of the boundary between the Chumashan-speaking Obispeño Chumash and their northern neighbors, the Hokan-speaking Salinan, is debatable (Milliken and Johnson 2005); however, Jones and Waugh (1995:8) note that “those boundaries may well have fluctuated through time in response to possible shifts in economic strategies and population movement.” The Chumash spoke six closely related Chumashan languages, which have been divided into two broad groups—Northern Chumash (consisting only of Obispeño) and Southern Chumash (Purisimeño, Ineseño, Barbareño, Ventureño, and Island Chumash) (Mithun 2004:389). One Spanish manuscript containing known text of the Obispeño dialect is housed within the special collections archives at the Bancroft Library (Allen et al. 1954). The Chumashan language currently is considered an isolate stock with a long history in the Santa Barbara region (Mithun 2004:304). Groups neighboring the Chumash included the Salinan to the north, the Southern Valley Yokuts and Tataviam to the east, and the Gabrielino (Tongva) to the south. Chumash place names in the project vicinity include Pismu (Pismo Beach), Tematatimi (along Los Berros Creek), and Tilhini (near San Luis Obispo) (Greenwood 1978:520). Only a general outline of the lifeways of the Obispeño Chumash is known based on the little ethnographic information available (Greenwood 1978). Although their language was closer to Southern Chumash groups, the material culture and lifeways of the Northern Chumash appear to have been more similar to their northern neighbors, the Salinan. Accordingly, their populations in this area are thought to have been substantially lower than in the Santa Barbara Channel area, their villages smaller, and their livelihood less based on intensive use of marine fisheries (Glassow et al. 1988; Greenwood 1978). Permanent Chumash villages included hemispherical dwellings arranged in close groups, with the chief having the largest for social obligations (Crespi 2001). Each Chumash village had a formal cemetery marked by tall painted poles and often with a defined entrance area (Gamble CHC 1-64 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 23 et al. 2001:191). Archaeological studies have identified separate sections for elite and commoner families within the cemetery grounds (King 1969). The acorn was a dietary staple for the mainland Chumash, though its dominance varied by coastal or inland location. Chumash diet also included cattail roots, fruits and pads from cactus, and bulbs and tubers of plants such as amole (Miller 1988:89). On the coast, the wooden plank canoe (tomol) was employed in the pursuit of marine mammals and fish. The tomol not only facilitated marine resource procurement but also facilitated an active trade network maintained by frequent crossings between the mainland and the Channel Islands. Chumash populations were decimated by the effects of European colonization and missionization (Johnson 1987). Traditional lifeways largely gave way to laborer jobs on ranches and farms in the Mexican and early American periods. Today, the Santa Ynez Band of Chumash Indians is the only federally recognized Chumash tribe, though many people of Chumash descent continue to live throughout their traditional territory. 3.4 HISTORICAL OVERVIEW Post-European contact history for California is generally divided into three periods: the Spanish Period (1769–1822), the Mexican Period (1822–1848), and the American Period (1848–present). The Spanish Period brought the establishment of the California mission system, while the Mexican Period is largely known for the division of the land of California into private land holdings. Following the Mexican-American war, the United States purchased California from Mexico; population of the state subsequently increased, particularly during the Gold Rush. 3.4.1 Spanish Period (1769–1822) Initial European entry into the San Luis Obispo region began with the Juan Rodrigues Cabrillo Expedition in 1542. Cabrillo sailed along the coast, possibly landing in Morro Bay, and then continued as far north as San Francisco Bay (Chesnut 1993). In 1587, Pedro de Unamuno landed in what was most likely Morro Bay, but suffered casualties during an attack by Native Americans and left (Bean 1968). Sebastian Rodriguez Cermeño entered the San Luis Obispo region in 1595 as part of his exploration of the Alta California coast (Jones et al. 1994). The earliest detailed descriptions of the area come from members of Gaspar de Portolá’s land expedition, which passed through the region in 1769 (Squibb 1984). Early travelers in the Central Coast region reported seeing no large Native American villages like those noted in the Santa Barbara Channel area. Gaspar de Portolá and Franciscan Father Junípero Serra established the first Spanish settlement in Alta California at Mission San Diego de Alcalá in 1769. This was the first of 21 missions erected by the Spanish between 1769 and 1823. Portolá continued north, passing through the project vicinity and reaching San Francisco Bay in 1769. Mission San Luis Obispo de Tolosa was founded in 1772, the fifth of 21 missions established by the Spanish in Alta California (Rolle 2003). CHC 1-65 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 24 3.4.2 Mexican Period (1822–1848) The Mexican Period commenced when news of the success of the Mexican Revolution (1810- 1821) against the Spanish crown reached California in 1822. This period saw the federalization of mission lands in California with the passage of the Secularization Act of 1833. This Act enabled Mexican governors in California to distribute former mission lands to individuals in the form of land grants. Successive Mexican governors made more than 700 land grants between 1833 and 1846, putting most of the state’s lands into private ownership for the first time (Shumway 2007). The land around Laguna Lake was originally part of a rancho associated with the Mission San Luis Obispo de Tolosa. In 1844 Governor Manuel Micheltorena granted the Church one square league or approximately 4,157 acres of land in the place called Laguna (Engelhardt 1915). In 1845 Governor Pio Pico sold the remaining mission lands and buildings to Captain John Wilson and his partners Scott and McKinley $500 (Angel 1883 and Mission San Luis Obispo, n.d.). The distribution of lands following secularization of the missions resulted in the granting of 40 ranchos in what is today San Luis Obispo County (San Luis Obispo County Genealogical Society, n.d.). The Mexican ranchos were primarily utilized to raise cattle herds and for farming (HRG 2013). 3.4.3 American Period (1848–Present) The American Period began with the signing of the Treaty of Guadalupe Hidalgo in 1848, which marked the end of the United States’ war with Mexico. The United States agreed to pay Mexico $15 million for the conquered territory, including California, Nevada, Utah, and parts of Colorado, Arizona, New Mexico, and Wyoming. The existing Mexican land grants were expected to be recognized, but over time, as settlement increased throughout the state, disputes arose between rancheros and settlers. Rancho owners expended much money and effort attempting to defend their land holdings. The California territory officially became a state in 1850 and the County of San Luis Obispo was established as one of the state’s original 27 counties. That same year, William Hutton was authorized to survey and lay out the town of San Luis Obispo (Angel 1883). The region suffered a severe drought between the years of 1862 and 1864 which decimated the cattle herds (HRG 2013). Rancheros struggled with this loss of income, debt, and costs incurred from legally defending their land under the new American law. As a result, many of the rancho lands were sold or lost. Most were subdivided into agricultural parcels or towns. Bishop Joseph Alemany petitioned the U.S. government to return a portion of the mission lands back to the Church. In the mid-1850s approximately 53 acres of the former mission lands were returned to the Church as well as the 4,157 acre Laguna Rancho (Mission San Luis Obispo, n.d.; California Office of Surveyor-General 1886; Morrison, et al 1917). Bishop Alemany sold the Laguna property to Captain John Wilson in late 1859 (Kocher 1972). In the early 1860s, W.W. Stow, an attorney and politician from San Francisco, purchased the Laguna Rancho from Wilson (The San Francisco Call 1895). The rancho was subdivided in 1868 when it was surveyed by James Stratton along with Rancho Cañada de los Osos (Bertrando 1999a). CHC 1-66 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 25 By April 1887, an estimated 3,000 to 4,000 people inhabited the region, and land prices increased dramatically. In 1894, the Southern Pacific Railroad completed a line from San Jose to San Luis Obispo encouraging trade and further settlement of the region. As the population increased in the town, Laguna Lake became a popular area for duck hunting and black bass were stocked in the lake. By 1896 farmers around the lake, growing mostly barley at that time, posted “No Hunting Allowed” signs throughout the area, as the popularity of the lake became troublesome to the surrounding landowners (Tognazzini 1996). In the early twentieth century Port Harford was renamed Port San Luis, and oil from the Santa Maria and Taft-Coalinga fields was shipped beginning in 1907 and 1913, respectively. The California Polytechnic School was established in 1901 as a high school and eventually became California Polytechnic State University (Cal Poly). The county’s agriculture and ranching production supplied U.S troops during World War I and helped its residents weather the Great Depression of the 1930s. At the start of World War II, the U.S. War Department transferred nearly 100,000 military personnel to bases at Morro Bay, Camp San Luis Obispo, Camp Roberts, and Cambria. 3.4.4 Dalidio Ranch Complex The subject property is comprised of several lots that were subdivided in 1875, when the Laguna Rancho was sold off into plots for small family farms. These lots were designated as 64, 65 and K, L, M and N (Bertrando 1999a). Lucian Garcia and Domingo Machado collectively owned 55 acres on the eastern end of lots 64 and 65. Each property consisted of a farm complex with a home. In 1887, H.M. Warden acquired Machado’s land. Warden deeded part of the property to George Steele in August of 1897 (Bertrando 1999a). A portion of the subject property was transferred to W. F. Wood from Samuel Look in 1894, and another portion was deeded to Wood by George Steele in 1900 (Bertrando 1999a). A horse race track existed below the Wood ranch, along with stables and a structure that provided seating for town people to watch the races. The track was located in what today is the agricultural field south of the ranch complex (Martin 2015; Froom in Bertrando 1999a). The building that held the spectators has been referred to as a “spectator’s barn”, “viewing stand” or “grand stand.” A local newspaper reported in November of 1900 that William Wood had purchased the race track property and was converting the grandstand into a residence. The article stated that the race track would probably be a thing of the past since Wood was a farmer and was considering destroying the track to make a grain field (SLO Semi Weekly Breeze 1900). In 1910 part of the ranch was deeded to Forest W. Wood as a wedding gift from his parents (Bertrando 1999a; Martin 2015). Forest’s father, William F. Wood, had moved part of the family to Glendale in late 1909 in order to be closer to two of their children attending a university there. Forest Wood remained in San Luis Obispo to continue farming (Oxnard Courier 1909). Forest reportedly moved the spectator barn/viewing stand, on rollers, to its current location on the ranch property. A small house that exists on the property was originally connected to the spectator barn. Forest removed this portion of the building, moved it to its present location and constructed a side wall on the building. It became part of Forest’s and his wife Ann’s original home before their new ranch house was constructed. Forest and Ann raised five children while operating a farm and small dairy (Martin 2015; Bertrando 1999a). The stables that had been CHC 1-67 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 26 associated with the race track may have been moved to the Pacific Beach School area (near present-day Los Osos Valley Road and Froom Ranch Way) and later torn down when the school was started (Froom in Bertrando 1999a). The spectator’s barn/viewing stand was further altered by the addition of a dairy, stables and conversion of the spectator seating area to hay storage. Florino and Katie Dalidio purchased the 150-acre property from the Wood family and farmed crops such as onions, artichokes, and garbanzo beans, as well as flowers for seed in 1921 (Bertrando 1999a; Stewart 1999). Florino Dalidio had immigrated to the United States from Switzerland in 1888 (Ancestry 2004) and after had married Katie Filipponi in 1907. They settled in Cayucos and had three children: Ernest, Melvin and Thelma. In 1917, Florino and Katie purchased 776 acres on Toro Creek, between Morro Bay and Cayucos, to the northwest of San Luis Obispo where they farmed, raised dairy cattle, and operated dairies along the coast. Following the purchase of the Wood family property they switched to row crop farming (Bertrando 1999a; Stewart 1999). Florino and Katie’s son Ernest eventually took over the family business. The Dalidio’s acquired additional land in the area either by purchase or leasing, including property in Harmony Valley (Bertrando 1999a; Stewart 1999). Ernest married Rose Navoni and they had one son: Ernest Jr. or Ernie. Ernie was raised in the secondary residence on the property (981 Madonna Road). After graduating from Cal Poly San Luis Obispo, he also went into the family business, dividing his time between the various family properties for many years. The Dalidio’s agricultural business was known as Zapata Farms starting in the early 1980s (Bertrando 1999a; Stewart 1999). Ernie sold the property in 2014 and the property has been renamed San Luis Ranch. 3.4.5 Agriculture in San Luis Obispo The Laguna area developed into farms, dairies and ranches (Bertrando 1999a). Wool, flour, and dairy were important income generating products in the area. Some of the most significant agricultural crops in the late 1800s were wheat, barley and beans. Grain from area ranchos was processed at local mills. Since San Luis Obispo was the major settlement in the area, some ranchers would travel from up to forty miles away to bring their grains into the city to be milled. Production increased when steam-powered mills were constructed starting in the 1870s. Ranching and agriculture were the region’s main commercial enterprises at one time and thus had an impact on the development of the city (HRG 2013). Roads were also constructed throughout the county in the 1870s, primarily by Chinese laborers, leading to increased mobility throughout the county. In 1872, Captain John Harford began construction on the Pacific Coast Railway which ran just to the east of the subject property. The railway improved shipping methods of local crops and products, advancing the economy (HRG 2013). In 1882, a project was undertaken to reclaim part of the Laguna Lake to allow for cultivation of the land. A ditch was dug from the lake’s outlet to Foreman Creek and tules were cut down to eliminate the black birds who resided in them because the birds destroyed the grain crop. Chinese laborers were utilized on the project (Tribune 1882; Bertrando 1999a). A dairy industry began developing in San Luis Obispo County in the late 1860s after the drought years of 1862-64. A well-known and sizeable dairy operation was George and Edgar Steele’s 45,000 acre property in Edna Valley stocked with more than 600 milking cows. The CHC 1-68 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 27 Steeles employed more than 100 men to build fences, milking sheds and maintain the hay fields. Their success started the dairy boom between Point Sal to the south of San Luis Obispo and Point Piedras Blancas to the north (Krieger 2012; Krieger 2014). Immigrants of Portuguese and Italian Swiss descent made a significant contribution to the development of the dairy industry in the region (Krieger 2012; Krieger 2014). The Italian wars of independence (the third war taking place in 1866) had disrupted the traditional routes of commerce and young men from dairying families began immigrating to the United States. Historian Glenn S. Dumke (1944) described San Luis Obispo County during the California land boom of the 1880s as “the great butter and cheese belt of southern California,” initially with land affordably priced between $18 and $25 per acre. Several prominent creameries and cheese factories were established in San Luis Obispo, many of which continued to flourish throughout the early 1900s (HRG 2013). During the 1880s beans were the primary crop grown south of the city of San Luis Obispo and continued into the early years of the 20th century (Bertrando 1999b). Other significant agricultural crops in the area in the early 20th century included winter peas, celery and flower seed. Japanese farmers in particular were successful with these crops through the 1930s. During World War I the demand for agricultural products increased, benefiting California farmers. Many area farmers began growing navy beans since this product was subsidized by the War Relief Administration (HRG 2013). 3.4.6 Horse Racing in San Luis Obispo Horse racing was documented to be a popular sport in the region since the time of the Mexican ranchos in the first half of the 19th century. In his history of San Luis Obispo County, Myron Angel described the California rancheros – descendants of the Mexican colonists – as being excellent horsemen. Horse-racing was one of the main sources of entertainment at the time, along with bull fighting and dancing (Angel 1883:56). A number of newspaper articles discuss horse racing tracks in the area, including a track that was prepared by a Mr. Gerhard Leff in 1874. Described as a permanent half-mile track approximately 2 to 3 miles south of town, it was something that had never before existed in the county (Tribune 1874a; Tribune 1874b). A mile long track was reportedly put in by a Mr. N.A. Cook on the Harford property in late 1875, and in 1885 Charley Woods established a training school and a half-mile track (Tribune Weekly 1875; SLO Tribune 1885). In 1887 the property of a Mr. McCoppin was being assessed to locate a site for a race track. McCoppin was willing to sell any amount of land to the Fair Association for $250.00 an acre. His property appears to have been in the vicinity of Lots 17 and 26 of the Foreman Survey, as that was the location that he reportedly would give the right-of-way (SLO Tribune 1887). It is unknown if the Fair Association ultimately developed a race track on McCoppin’s property. Over the summer and fall months of 1887 newspaper articles mention the Fair Association, the SLO County Agricultural Association and the SLO Park Association as being involved in establishing the race track for the local fair. It seems that it was the SLO Park Association which ultimately purchased 100 acres of land approximately 1 ¼ mile southwest of the city. A one- mile long race track, a grand stand, judges’ stand and stalls were completed in October of 1887 (SLO Tribune 1887; Tribune Weekly 1887). CHC 1-69 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 28 Bill Froom, a long-time resident of the area, was quoted as saying that he recalled hearing about another half-mile race track in the vicinity of Madonna Plaza, which would be slightly to the northeast of the Wood/Dalidio property (Bertrando 1999a). Horse races were still taking place in the area during the county fair in the fall of 1900, as mentioned in the local newspaper. The location of the fair’s track, however, was not specified at the time (Semi Weekly Breeze 1900a). In November of 1900 the local newspaper reported that William Wood had purchased “the race track property” and was converting the grand stand building into a residence. The article speculated that the race track would “probably be a thing of the past” since Wood was a farmer and was considering making the area of the track into a grain field (Semi Weekly Breeze, 1900b). In an oral interview, local Bill Froom stated that when the viewing stand was moved into the Wood farm complex the track was shortened by a half mile (Froom in Bertrando, 1998). It is not known for certain whether the race track established for the SLO Park Association in 1887 for use during that year’s fair is the same race track that existed on the Wood/Dalidio ranch property. However, the description of the race track being located 1 ¼ miles southwest of the city and having a grand stand and stables suggest it could be the same since the race track on the Wood/Dalidio property had those amenities. Besides being a popular sport which involved horse owners, trainers, riders and undoubtedly wagering spectators, the races also functioned as a social event. As described by Bill Froom, crowds of people would park under the trees and have picnics before the races started (Froom in Bertrando, 1999a). Horse races were also held in conjunction with the local fair. A horse racing facility could typically include the race track, stables, a judge’s stand, and a viewing stand for spectators. The former viewing stand on the Dalidio Ranch property was likely similar to a known existing late 19th century grandstand located on the Deerfield Valley Agricultural Society Fairgrounds in Charlemont, Massachusetts (Figure 3). The two structures, both built in the same time period, are similar in size, design, and plan. The diagonally slanted window openings on the Dalidio Ranch structure can be explained by the open seating/ viewing area seen on the intact Charlemont grandstand. The viewing stand at the Dalidio Ranch no longer has this open seating/viewing area. It appears to have been enclosed as the structure was repurposed into a dairy, stable, and hay barn. With the increased popularity of the automobile, horse racing eventually died out in San Luis Obispo. By the 1920s automobile races were held locally on a large track located off of South Street (Bertrando, 1999a).

CHC 1-71 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 30 4.0 BACKGROUND RESEARCH Background research for the current study encompassed both the project site and a half-mile radius surrounding the project site. Background research was conducted to determine if cultural resources are present within the project area. The background research conducted for this study includes Native American scoping, a review of cultural resource records at the California Historical Resources Information System (CHRIS) Central Coast Information Center (CCIC), and archival research. 4.1 NATIVE AMERICAN SCOPING Rincon conducted Native American scoping for the San Luis Ranch Project to identify potential concerns or issues associated with Native American cultural resources within the project vicinity. Rincon contacted the Native American Heritage Commission (NAHC) to request a review of the Sacred Lands File (SLF) on January 6, 2016. The NAHC responded by email on January 27, 2016 stating that the search of the sacred land files has “failed to indicate the presence of Native American cultural resources in the immediate project area.” The NAHC also provided a list of Native American groups and individuals who may have knowledge of cultural resources within the project site. Rincon prepared and mailed letters to each of these contacts requesting any information they may have regarding Native American cultural resources within the project site on February 8, 2016. On March 3, 2016, Rincon Archaeologist Breana Campbell conducted follow-up consultation by telephone. Voicemail messages were left for each of the consultants who did not answer. The NAHC correspondence and Native American communication is documented in Appendix A. The following responses were received as a result of the Native American scoping process. Ms. Julie Lynn Tumamait-Stenslie, Chair of the Barbareño/Ventureño Band of Mission Indians, requested that extended Phase I testing of the project site with trenching up to a depth of four to five feet be conducted by a qualified archaeologist with a qualified Native American monitor present, due to the proximity of Native American sites and the proximity of Prefumo Creek to the project site. If no testing occurs prior to the project initiation, Ms. Tumamait-Stenslie recommended that an archaeologist be present for any ground disturbing activities. Mr. Raudel Joe Banuelos, Jr. of the Barbareño/Ventureño Band of Mission Indians requested to be contacted following the intensive pedestrian survey and informed of the results. Ms. Mona Olivas Tucker, Chairwoman of the yak tityu tityu – Northern Chumash Tribe, responded via email and inquired about the background records search results, following a discussion with Rincon staff, Ms. Tucker noted that encountering cultural resources within the project boundaries is likely. As of October 2016, no additional responses have been received. CHC 1-72 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 31 4.2 CALIFORNIA HISTORICAL RESOURCES INFORMATION SYSTEM Rincon requested a search of the cultural resource records housed at the CHRIS CCIC located at the University of California, Santa Barbara on January 25, 2016. The search was conducted to identify previous cultural resources work and previously recorded cultural resources within the project site as well as within a 0.5-mile radius of the project site. The CHRIS search included a review of the NRHP, the CRHR, the California State Historical Landmarks list, the California Points of Historical Interest list, historic building surveys, the Archaeological Determinations of Eligibility list, and the California Inventory of Historical Resources list. It provided information about archaeological resources, historic resources, and reports within the project site as well as within a 0.5-mile radius of the project site. Rincon received the cultural resource record search results from the CCIC on February 2, 2016. The cultural resource records search of the CCIC inventory identifies 51 reports from projects previously conducted within the project site as well as within a 0.5-mile radius of the project site. No archaeological or historic resources were identified within the project area, but two historic resources, four archaeological sites, and two isolated cultural resources have been identified within a 0.5-mile radius of the project site. The CCIC does not list any historic addresses within the search radius, nor does the CCIC possess any historical maps depicting the project site. The cultural resource records search conducted at the CCIC yield no additional information. 4.2.1 Previous Studies The CCIC records search identified 51 reports for studies previously conducted within the project site as well as within a 0.5-mile radius of the project site. Of these, eight previous studies overlap with or were located within the project site area (Table 1). The remaining 43 studies were conducted outside the project site (Table 2).

Of these, one is located within the project site: Dalidio Ranch/San Luis Ranch complex (P-40-041000), a complex of historic buildings; this resource is discussed in more detail below. The remaining eight resources are located outside of the project site and consist of three prehistoric archaeological sites (P-40-000124, P-40-000400, P-40-001406), one historic archaeological site (P-40-001449), two historic built environment resources (P-40- 040139, P-40-040991), and two prehistoric isolated artifacts (P-40-038206, P-40-038212).

Singer and Atwood (1988) conducted a cultural resources survey of the project site in 1988, and identified “two wood frame structures, a large, two-story house and a barn” as having potential historical significance. Betsy Bertrando recorded and evaluated the complex in 1999 for the Dalidio Marketplace project concept (see 1.2 Project Background). The complex, as recorded by Bertrando (1999b), comprises eight historic built environment resources: the Dalidio Home, a bungalow, a small shed/bunkhouse, a garage, a water tower, a barn, a large equipment storage building, and the former race track spectators’ barn/viewing stand. The resources are located at the northwest end of the property. 4.3 ARCHIVAL RESEARCH Rincon reviewed historic aerial photographs, topographic maps, and the Bureau of Land Management (BLM) General Land Office (GLO) Records from internet sources to better understand the land use history of the project site; 31 historic maps were available for review. The earliest available historic aerial photograph that depicts the project site is from 1960, but the resolution is too low to better understand the land use history of the project site (Nationwide Environmental Title Research, LLC 2016, USGS 2016). 31 historic topographic maps were available for review. Three plat maps from the BLM GLO Records were available for review. The 1867 plat map of San Luis Obispo depicts the project area as “Part of the Laguna Rancho Lot No. 37.” This map also depicts a “Road to the Port of San Luis Obispo,” which appears consistent with the current alignment of U.S. Route 101. The 1872 and 1875 plat maps of San Luis Obispo also depict the project site at part of the Laguna Rancho Lot No. 37. The Master Title Plat map of 1877 depicts the project site as the “Laguna Grant 332.” While plots of land surrounding the project site were divided in the late nineteenth century, the project site itself remained as one large parcel. The earliest USGS map of the area is the 1903 reprint of the 1897 San Luis Obispo, CA 15-minute topographic map, accessed through the online USGS US Topo and Historical Map Collection. This map depicts the historic race track located in the current project site. The Pacific Coast Railroad alignment, which is currently used as the alignment for US Route 101, is also depicted on this map. The historic race track is present on the 1931 reprint of this map, but does not appear on the 1942 San Luis Obispo, CA 15-minute topographic map or its 1948 reprinted edition. No other features were identified within the project site from historic topographic maps. CHC 1-77 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 36 5.0 RESEARCH DESIGN The current study included the archaeological testing of site SLR-S-1 for CRHR/NRHP eligibility evaluation. Rincon archaeologists determined that the site could be eligible for the CRHR/NRHP under Criterion 4/D for the site’s potential to provide pertinent information to local prehistory. Therefore, Rincon conducted a Phase II investigation to determine if site SLR-S- 1 retains intact deposits and significant data potential. The following research questions were considered to aid in this determination.  Are subsurface deposits present and, if so, do they retain integrity? Can discrete features or temporal episodes be identified in the vertical and/or horizontal layout of the site?  Are any discrete concentrations of artifacts present across the site?  When was the site occupied?  What temporal period/cultural complex does the use of the site correspond with?  How does the site relate to broader patterns of subsistence/settlement established for the Central Coast?  What resources were utilized? What was the primary subsistence activity? (hunting vs. foraging; large game vs. small game; roots vs. seeds, etc.)  What was the function of the site? Is there evidence of distinct artifact types or styles at the site?  What types of lithic artifacts are present and what activities do the artifact types represent?  Are there any non-local material or artifacts present at the site representing evidence of mobility and/or interregional interaction? CHC 1-78 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 37 6.0 METHODS Rincon conducted archival research and examined the City of San Luis Obispo’s Historic Context Statement prior to completing the intensive archaeological and built environment surveys. Archival research included an examination of historic maps, aerial photographs, and written histories of the area as well as consultation with repositories, publications, and individuals who may have additional knowledge of the project site. 6.1 ARCHIVAL RESEARCH Archival research was completed between February and March 2016. Research methodology focused on the review of a variety of primary and secondary source materials relating to the history and development of the project area. Sources included, but were not limited to, historic maps, aerial photographs, and written histories of the area. The following repositories, publications, and individuals were contacted to identify known historical land uses and the locations of research materials pertinent to the project site: • History Center of San Luis Obispo County • Historic aerial photographs • United States Geological Survey Maps • Sanborn Fire Insurance Company Maps • City of San Luis Obispo, Utilities Department • County of San Luis Obispo Planning and Building • County of San Luis Obispo Public Works • Other sources as noted in the references list 6.2 CITY OF SAN LUIS OBISPO HISTORIC CONTEXT STATEMENT The City of San Luis Obispo developed a Citywide Historic Context Statement in 2013 to identify and evaluate potential historic resources. Potential historic resources are examined within a series of contexts. Early 20th Century Development and Early 20th Century Agricultural & Industrial Development are examined in further detail below. 6.2.1 Context: Early 20th Century Development Development of the project site into a farm complex began in 1900, which falls under the context of Early 20th Century Development (1900-1929). The city’s development during this time was characterized by the introduction of the Southern Pacific Railroad, population growth, increased use of the automobile, and the city’s expansion. 6.2.2 Theme: Early 20th Century Agricultural & Industrial Development The Dalidio Ranch is representative of the theme of Early 20th Century Agricultural and Industrial Development. During this time period ranching and agriculture were the main commercial enterprises in the region, directly influencing the development of San Luis Obispo. The Dalidio Ranch property has been in agricultural use for over 100 years. The proposed project calls for annexation into the City of San Luis Obispo; thus, the Dalidio Ranch would be a rare, intact example of an early 20th century family farm complex with its associated buildings CHC 1-79 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 38 and agricultural fields within the city limits. Agricultural and industrial properties are typically not associated with particular architectural styles and often contain vernacular buildings. A property’s significance under this theme is frequently derived from historic association rather than aesthetic qualities. 6.2.3 Property Types & Eligibility Standards Examples of agricultural property types from this period include farmhouses, warehouses and related outbuildings. An agricultural or industrial property from this period may be considered significant under the following criteria:  Criterion A/1/B.2 (Event). As a rare example of a specific agricultural or industrial property type - Criterion C/3/A.1, A.2 (Design/Construction).  As a property type that has a direct association with the railroad – Criterion C/3/A.1, A.2 (Design/Construction). In addition, in order to be eligible for listing at the federal, state or local levels, a property must retain sufficient integrity to convey its historic significance under the Early 20th Century Agricultural and Industrial Development theme including:.  Agricultural and industrial properties from this period eligible under Criteria A/1/B.2 (Event) should retain integrity of location, design, feeling, and association.  Agricultural and industrial properties significant under Criterion C/3/A.1, A.2 (Design/Construction) should retain integrity of location, design, materials, workmanship, and feeling. The following eligibility standards must also be met. The property must:  date from the period of significance;  display most of the character-defining features of the type;  retain the essential aspects of integrity. 6.3 CULTURAL RESOURCES SURVEYS Rincon Cultural Resources Specialist Ashlee M. Bailey, M.A., conducted the intensive pedestrian survey of the project site for archaeological resources between March 14, 2016 and March 16, 2016. Ms. Bailey examined the ground using transects spaced no greater than 15 meters apart and oriented northeast to southwest for the entire project site. Rincon Architectural Historian Susan Zamudio-Gurrola, M.H.P., conducted an intensive-level built environment survey of the project site on March 15, 2016. Ms. Zamudio-Gurrola examined, documented, photographed, and evaluated all of the built environment features for the project site. 6.3.1 Archaeological Survey Ms. Bailey examined all exposed ground surface for artifacts (e.g. flaked stone tools, tool- making debris, stone milling tools, ceramics, fire-affected rock [FAR]), ecofacts (marine shell and bone), soil discoloration that might indicate the presence of a cultural midden, soil CHC 1-80 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 39 depressions, and features indicative of the former presence of structures or buildings (e.g. standing exterior walls, postholes, foundations) or historic debris (e.g. metal, glass, ceramics). Ground disturbances, such as animal burrows and drainages, were visually inspected because these disturbances can expose subsurface deposits. 6.3.2 Built Environment Survey The purpose of the built environment survey was to identify and photograph any built environment resources that may be impacted by the proposed project. Ms. Zamudio-Gurrola conducted a visual inspection of all built environment features of the property, including buildings, structures, and associated features to assess the overall condition and integrity, and to identify and document any potential character-defining features. Field documentation included digital photographs of the property to support field observations. 6.4 ARCHAEOLOGICAL TESTING Upon identification of SLR-S-1 within the project site, Rincon recommended a Phase II investigation to evaluate the CRHR/NRHP eligibility of the site between August 1 and 16, 2016. The Phase II investigation was meant to establish the vertical and horizontal limits of site SLR-S- 1 within the project site and to determine if intact deposits are present. To complete the Phase II investigation, Rincon pin flagged the outmost surface expression (i.e., extent of surface artifacts) and excavated one test unit (TU), 21 auger tests (AUG), and two shovel test pits (STP) to appropriately determine the site boundaries and collected surface artifacts (Figure 4). Rincon placed the STPs and AUGs within the surface scatter identified during survey and extending outward in 10 to 15 m intervals in order to determine the site boundaries and the presence or absence of buried cultural material. STPs and AUGs were excavated in approximately 10- to 15- centimeter (cm) levels as measured from the ground surface. TU-01 was placed in the center of a cluster of STPs/AUGs that were positive for cultural material and was excavated in 10-cm levels as measured from an arbitrary datum set at the ground surface. Excavated soils were screened through 3-millimeter (mm) (1/8-inch) wire mesh. All data was recorded on standard archaeological forms. Artifacts and ecofacts recovered were collected and bagged with pertinent data recorded (e.g., provenience data), as appropriate. All excavations were backfilled upon completion of testing. 6.5 LABORATORY Rincon transported all collected materials to the San Luis Obispo office laboratory for temporary storage, cataloging, and analysis. Rincon archaeologists used the following laboratory methods to process and analyze cultural materials recovered during the Phase II site evaluation to generate data that could be used to address questions posed in the Research Design and create a database for future research. Field records and photographs were digitally saved to the project archive. Rincon archaeologists cataloged all artifacts, ecofacts, and sample materials recovered from the Phase II investigation as individual items or in lots, where appropriate (e.g., debitage of the same material class and stage of reduction from the same provenience). All collected materials were cataloged as part of site CA-SLO-2825. CHC 1-81 Attachment 2 Confidential information has been removed from this document. CHC 1-82 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 41 Cataloged items were enumerated sequentially with the provenience serving as the accession number. All catalog information was stored in a Microsoft (MS) Excel spreadsheet. The spreadsheet recorded provenience information (location and depth); date collected; and descriptive information such as artifact class, artifact type, material type, condition, count, and weight. In addition, all cataloged flakes were assigned a size grade to assess the variety of flakes present, and the various potential activities that took place at the site. 6.6 ARTIFACT ANALYSIS The type and extent of analytical studies appropriate for the Phase II evaluation was determined by the nature and size of the site collection. The small prehistoric assemblage consists of flaked stone, primarily debitage, and one fragmented Pismo clam shell. Methods used during the analytical studies are summarized below. Results are presented in the Section 6.0, Results. 6.6.1 Lithic Analysis Following cataloguing, Rincon conducted specialized analysis for flaked stone artifacts recovered from SLR-S-1. Artifacts were studied to determine their age, evidence of use wear, and other traits that may contribute to addressing the research questions. Comparisons were made to cross date the artifacts in relation to other similar regional occurrences of the artifact type. Projectile Points Projectile points are typically manufactured through percussion reduction. Many projectile points are bifacial and exhibit a hafting element, with the caveat that not all hafted stone tools were used as projectiles. Many points exhibit use-wear from multiple activities, including cutting and scraping (Andrefsky 2007:204). Further, some projectile points are unifacial and/or do not exhibit a hafting element, but were hafted and used as projectile points. Classification and chronological interpretation of the projectile point in the CA-SLO-2825 collection are based on comparisons with those points along the California Central Coast (Justice 2002). Metric attributes were recorded as defined by Thomas (1970, 1981). Bifacial tool fragments that might be projectile point parts, such as distal tips and medial sections, were classified as biface fragments for the current analysis. Bifaces The identification of bifaces in the CA-SLO-2825 collection follows Andrefsky (2007), who defines bifaces as stone artifacts exhibiting flake removals from both surfaces and which cannot be morphologically classified as another type of flaked stone artifact such as a core, projectile point, or drill. Many non-diagnostic bifacially flaked stone artifacts are likely preforms for the manufacture of projectile points or other bifacial tools such as knives. The 10 bifaces in the site collection are classified by manufacture stage to facilitate the study of flaked stone tool production and maintenance at CA-SLO-2825. Bifaces recovered from CA-SLO-2825 are classified into 10 manufacture stage categories, which include the five stage classification system as well as five general classifications. Biface manufacture stage classifications follow a five stage adaptation (Andrefsky 2007:Figure 7.33) of Callahan's (1979) more comprehensive stage classification system. Stage 1 consists of a flake blank or cobble without further modification. Stage 2 bifaces exhibit flake removals along the margins of the blank, typically CHC 1-83 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 42 referred to as an edged biface. Additional shaping and biface thinning occur during Stage 3. Stage 4 consists of a nearly complete artifact with additional thinning flakes removed, which are often referred to as preforms. Stage 5 consists of either completed, thinned bifaces or completed, thinned projectile points. Additional categories refer to more general classifications, and include Early, early/mid, mid, mid/late, and late stages; these categories subsume bifaces that cannot be clearly defined as one stage versus another. Edge Modified Flake Edge modified flakes (EMFs) are reduction flakes that have been intentionally modified by percussion or pressure as well as flakes with less invasive microflake edge modifications that could have been produced directly by use. Attributes recorded specifically for the EMF include the number of modified edges, the number of faces on which modification occurs, and the primary flake scar pattern. The number of edges available for modification (intentional or unintentional) varies from flake to flake. Here, continuous modification describes modification that begins on one margin, continues along the distal end of the flake, and extends onto the opposing margin. Bimarginal modification indicates modification that occurs on both of the lateral margins of the flake. Bimarginal modification includes two sub-groups: bimarginal continuous and bimarginal clustered. Bimarginal continuous modification describes an edge modified flake that exhibits continuous modification along the lateral margins, but not along the end, of the flake. Bimarginal clustered modification describes an edge modified flake that exhibits generally small, discontinuous clusters of flake removals in one or more isolated locations along both margins of the flake. Unimarginal modification indicates modification that occurs on only one margin of the flake; unimarginal modification is also separated into continuous and clustered variants. Cores Cores are masses of toolstone from which useable flakes were removed by percussion or bipolar reduction. Patterned flake removal maximizes the number of flakes that can be removed from the core. Patterned flake removals typically occur on cores of rare, non-local, and/or high quality lithic material. Patterned cores include unidirectional, bifacial, or bipolar cores. Multidirectional cores exhibit non-patterned flake removals and are typically made from local or relatively local lithic materials, such as Franciscan or Monterey chert. The quality of Franciscan chert varies throughout the Franciscan Complex with cobbles that typically exhibit coarse to fine-grained texture allowing the material to fracture conchoidally. Franciscan chert exhibits a range of texture that results in low to medium-high quality flaking properties. Some nodules contain inclusions that affect the workability of the material. Many multidirectional cores, especially those made from readily available sources, are discarded prior to exhaustion, because local lithic material (e.g. basalt), though abundant, is often of lower quality for the production of useful flakes. Cores made from higher quality lithic material are often reduced into very small forms, and sometimes are exhausted. An exhausted core is a core from which no additional useful flakes can be removed. This means the nodule has been maximized to yield as many useful flakes as possible until the core can yield no more useful flakes prior to discard. The face and direction from which the flakes were removed was recorded during the analysis of the cores in the CA-SLO-2825 assemblage. Andrefsky (2007) discusses problems with consistency in the comparison of cores, but offers a solution for the lithic analyst: the maximum linear dimension multiplied by the weight of the core provides a consistent unit of measurement for comparison. This consistent unit of CHC 1-84 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 43 measurement for the comparison of cores depends on the hypothesis that raw material quality and availability affects the patterns of use and discard of cores, and thus these measurements were recorded and as part of the analysis of cores in the CA-SLO-2825 assemblage. If raw materials influence the reduction technology of cores, then we should expect cores of quality, non-local lithic material to be small and/or exhausted. On the other hand, cores made from locally available, and generally lower-quality, toolstone are expected to be larger in size and typically discarded prior to exhaustion. Debitage Debitage are the waste flakes generated during the manufacture of flaked stone tools. A technological analysis of all the debitage in the CA-SLO-2825 collection was conducted to characterize predominant flaked stone reduction patterns. Reduction technologies are reflected by the relative proportions of diagnostic flake types present within a study area. Analysis of debitage recovered form CA-SLO-2825 included classifying individual specimens following the typological definitions by Andrefsky (1998:120 and 2001:6), Bloomer (2009), and Smiley (2007). The technological classification of each flake and the total count and weight of the debitage was recorded in order to characterize the predominant flaked stone reduction patterns. Core reduction and the initial reduction of flake blanks produce relatively high percentages of cortical and dorsally-simple interior flakes, a low frequency of edge preparation flakes, and no biface thinning or pressure flakes. Biface reduction, through the entire continuum of early (stage 2 and 3) to late stages (3 and 4) and pressure flaking (stage 5), results in a more varied flake assemblage. An assemblage entirely composed of late stage biface reduction debris will be dominated by late stage biface thinning flakes and pressure flakes, evincing only small frequencies of cortical flakes, interior flakes, edge preparation flakes, and early biface thinning flakes. The sizes of objective stage 5 bifaces also must be considered, because archaeological recovery methods (e.g., use of 1/4-inch screen) may preclude the recovery of small-size debitage produced by small bifaces and tools. Recorded attributes for the CA-SLO-2825 debitage include material, count, and weight by provenience (unit, level, screen size). Specific methods were used for the detailed debitage analysis, as follows. The debitage was sorted into lithic material classes and analyzed by provenience. The debitage was sorted through a set of nested wire mesh screens, sized from ½ in. (12.7 mm) and ¼ in. (6.35 mm), with a tray at the bottom to catch flakes smaller than ¼ inch but no smaller than ⅛ inch, since removed soils from the field units were dry-screened through ⅛ inch mesh. This separated the debitage into four size categories: between 2 inches and 1 inch; between 1 inch and ½ inch; between ½ inch and ¼ inch; and between ¼ inch and ⅛ inch. The reduction technology evident for any given debitage assemblage is characterized by the variable proportions of diagnostic flake types. Nine flake type categories are considered technologically diagnostic for analysis in the CA-SLO-2825 collection. These are defined below, and are followed by descriptions of less diagnostic flake types. Debitage - Diagnostic Flake Types Cortical. A flake with cortex, generally covering over 25 percent of its dorsal surface. Other flake types with small amounts of cortex, such as biface thinning flakes, are not classified as cortical flakes. CHC 1-85 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 44 Simple Interior. A non-cortical flake with three or fewer negative flake scars on its dorsal surface, not including platform preparation scars. Negative flake scar patterning on the dorsal surface is typically linear along the axis of the flake. Simple, single-facet platforms are typical. Simple Interior/Complex Platform. Same as a simple interior flake but with a complex platform with multiple facets. Complex Interior. A non-cortical flake with three or more negative flake scars on its dorsal surface, not including platform preparation scars. Negative flake scar patterning on the dorsal surface is not typically linear along the axis of the flake, but shows a complexity of scars emanating from various and opposing directions. Platforms are usually complex with multiple facets. Complex Interior/Simple Platform. Same as a complex interior flake but the platform is simple, usually with a single facet. Edge Preparation. A group of several distinct flake types which result from shaping an unworked edge of a flake blank. These flakes include edge preparation flakes, which are wider than they are long, with pronounced bulbs of percussion and large dorsal areas with few or no negative flake scars; bulb removal flakes, which retain a remnant of the flake blank’s ventral bulb of percussion; and alternate flakes, which are wider than long, and wedge shaped, resulting from the reduction of a thick square edge. Gull Wing. A flake that exhibits the appearance of a “gull wing” when viewed from the top of the striking platform. Gull wing flakes result from an impact that applies force directly behind the negative bulb of percussion from a previously removed flake. These flakes can be produced during platform preparation or unintentionally from the percussor impacting the objective piece more than once during a single stroke. Early Biface Thinning. An often slightly curved flake with a simple or complex bifacial platform and a few dorsal flake scars which emanate generally from the flake’s platform. Late Biface Thinning. A curved or flat flake with a bifacial platform and multiple dorsal flake scars, which may reveal a complex pattern of previous flake removals. Typical late stage thinning flakes retain partial dorsal scars showing previous flake removals from the opposite edge of the biface. Pressure. Typically small, thin flakes with few to multiple dorsal flake scars removed from prior pressure reduction. Platforms may be perpendicular or oblique to the longitudinal axis of the flake. Shapes vary from wide and short to long and narrow. Notching Pressure. Notching flakes result from notching a projectile point. Notching flakes are fan shaped, short and round, with the platform set into a depression. Rejuvenation. A flake that exhibits a complex and/or heavily abraded platform as well as multiple flake scars on the dorsal surface of the flake. Rejuvenation flakes indicate the CHC 1-86 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 45 resharpening of an edge of a tool that has become dull from heavy use. Rejuvenation flakes are typically removed alternately from each face of the tool. Bipolar. These flakes are a result of percussion from opposite directions at the same time, typically from placing the toolstone mass on an anvil and then down striking with a hard hammerstone from above. Flake attributes include crushing at opposite ends, with distinct cones of percussion and straight ventral and dorsal surfaces. Debitage - Flake Types of Less Diagnostic Value Platform Preparation/Pressure. Platform preparation flakes typically result from the light percussion of a bifacial edge to prepare a flake detachment platform. Pressure flakes are often indistinguishable from light percussion platform preparation flakes, and so this category subsumes less distinctive flakes, which may have resulted from pressure reduction. Eraillure. Typically small, thin flakes with no flake scars on the dorsal surface, as the dorsal surface of these flakes is the ventral surface of the objective piece (parent flake). These flakes leave a negative impression on the bulb of percussion on the ventral surface of the parent flake, and result from the percussor impacting the objective piece more than once during a single stroke. Cortical Fragment. Cortical flake fragments demonstrate a high percentage of cortex present on the dorsal surface, but cannot be definitively classified as cortical flakes, as the flake could demonstrate a differing reduction stage if complete. Simple Fragment. Simple flake fragments demonstrate morphological attributes of secondary flakes, but are incomplete; the flake cannot be classified definitively as a secondary flake, however, due to a missing platform, flake termination, or both, and could belong to another flake category. Complex Fragment. Complex flake fragments demonstrate morphological attributes of biface thinning or pressure flakes, such as a thin cross-section and multiple dorsal flake scars resulting from previous flake removals; the flake cannot be classified definitively, however, because the flake is incomplete. Shatter. Shatter results from flaked stone reduction, but demonstrates no typical flake attributes and the ventral or dorsal surfaces and proximal or distal ends cannot be determined. CHC 1-87 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 46 7.0 RESULTS AND DISCUSSION Three archaeological resources and one historic complex of buildings were identified within the project site. Rincon Archaeologist Ashlee Bailey, M.A., RPA, identified and recorded one prehistoric archaeological site (CA-SLO-2825) and two isolated prehistoric archaeological artifacts Rincon archaeologists recorded, tested, and evaluated CA-SLO-2825 to determine the eligibility for listing in the CRHR/NRHP). Rincon Architectural Historian Susan Zamudio- Gurrola, M.H.P., recorded and evaluated the historic San Luis Ranch complex, which includes three single-family residences, a garage/shed, a smaller shed, the main barn, a large equipment storage building, a warehouse, and the former spectator’s barn (viewing stand). State of California Department of Parks and Recreation (DPR) Series 523 forms were prepared for all cultural resources within the project site (Appendix C). No other cultural resources were identified within the project site during the field survey. 7.1 ARCHAEOLOGICAL RESOURCES Rincon recorded three newly identified prehistoric archaeological resources during the course of the intensive pedestrian survey. These include one prehistoric archaeological site (CA-SLO- 2825) and two isolated prehistoric artifacts (P-40-038327 and P-40-038328), located along the western edge of the San Luis Ranch agricultural field approximately 40 m east of the modern Prefumo Creek. Soils show minimal variation in composition, consisting primarily of 10 YR 4/3 brown clay with approximately 30 percent small rounded and gravel inclusions. Ground visibility in the agricultural field was good, estimated at approximately 75 percent during the survey. While the area has little to no slope, the aspect of San Luis Valley is generally to the south. State of California DPR Series 523 forms were prepared for the archaeological resources within the project site (Appendix C). Rincon conducted archaeological testing of the site to evaluate the CRHR/NRHP eligibility of the site. 7.1.1 CA-SLO-2825 Newly identified site CA-SLO-2825 is a discrete, low-density prehistoric lithic scatter located on the western edge of the San Luis Ranch agricultural field approximately 40 m east of Prefumo Creek (Photograph 1). The site measures 55 × 100 m (180 × 330 feet), encompassing both individually point plotted surface artifacts and subsurface test units positive for cultural materials (Figures 4 and 5). A total of 407 artifacts were recovered from the site, including 385 pieces of debitage, 21 flaked stone tools, and one fragmented Pismo clam shell. Of these, 84 artifacts were collected from the site surface while the remaining 323 artifacts were recovered from test excavation units. The subsurface component of redeposited lithic debitage extends to 40 cm below surface (cmbs). Surface Collection Rincon archaeologists conducted an intensive pedestrian survey of the site to identify its extent. A total of 84 artifacts were collected by individual point plot from the site surface. The artifacts include 64 pieces of debitage, one projectile point fragment, eight bifaces, one edge-modified flake, three assayed cobbles, four cores, two core fragments, and one fragmented Pismo clam shell. Some of the surface artifacts were identified in the unpaved road adjacent to the CHC 1-88 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 47 Confidential information has been removed from this document. Photograph 1. CA-SLO-2825 site overview with flags on artifacts, view toward west. agricultural field on the south; these artifacts were likely dragged and redeposited during plowing or other activities associated with crop cultivation and are thus not included within the mapped site boundary. Subsurface Testing Rincon archaeologists excavated a total of 24 subsurface test units, including one 1.0 × 1.0 m test unit (TU-01), two shovel test pits (STPs), and 21 auger tests (AUGs), within and around site CA- SLO-2825 between August 1 and 16, 2016. A total of 323 artifacts, primarily debitage, were recovered from 16 of the 24 test excavation units. Test Unit TU-01 Size: 1.0 × 1.0 m (north–south × east–west) Number of Levels: 05 Total Depth: 50 cmbs Reason for Termination: Sterile sediments Disturbances: Agricultural activities Rincon archaeologists excavated TU-01 to a depth of 50 cmbs (Photograph 2) and recovered 91 pieces of debitage to a depth of 40 cmbs. All artifacts were pieces of flaked stone debitage; no cores or formal tools were present (Table 4).Stratigraphy consisted of approximately 30 cm of loosely compacted 10 YR 4/3 brown clay (Stratum I) and approximately 10 cm of highly compacted 10 YR 3/3 brown fine-grained plastic clay (Stratum II) over 10 cm of 10 YR 4/6 dark yellowish brown sandy clay (Stratum III). Strata I and II are disturbed sediments that have been repeatedly mixed from the use of the area for agriculture over the past 100 years (Figure 6).

Photograph 2. Overview of TU-01, view toward north. Shovel Test Pits and Auger Test Units Rincon excavated two STPs (STPs 1 and 2) and 21 auger test units (AUGs 1 – 21). Of these, 17 were positive for cultural materials (Table 5). STP 1 yielded and contained a total of 91 and 53 pieces of lithic debitage, respectively. No other artifact types were identified within the STPs. All artifacts were recovered from less than 45 cmbs. Rincon also excavated 21 hand-excavated augers (AUG 1-21). Of these, 16 (AUG 1-7, 10-13, 16-17, and 19-21) were positive for cultural materials and the remaining five (AUG 8, 9, 14, 15, and 18) were negative for cultural materials. Rincon recovered a total of 98 pieces of lithic debitage and a small amount of yellow and red ochre. All artifacts were recovered from above 40 cmbs.

All subsurface artifacts were recovered from the upper 40 cm of the deposit, within disturbed sediments in the plow zone. CA-SLO-2825 Flaked Stone Analysis The flaked stone assemblage comprises 406 artifacts, of which 95 percent is debitage (n=385). Flaked stone tools (n=21) include one projectile point fragment, ten bifaces, one edge modified flake, and nine cores. The tools and debitage recovered during the current investigation are discussed in further detail below. Projectile Point The projectile point collected from CA-SLO-2825 consists of a reddish brown Franciscan cryptocrystalline silicate proximal/medial fragment. The tool was manufactured using non- patterned percussion reduction and exhibits a plano-convex cross section, convex margins, and a contracting stem. A snapping break removed the distal end of the point. Previous studies (cf. Bettinger and Eerkens 1999) suggest that projectile points heavier than three grams tend to be dart points, whereas points lighter than three grams are probably arrow points. The weight exceeding 3.0 g and its remnant neck width of 16.1 mm (which is >10 mm) are both measures that often have been used as thresholds for distinguishing arrow from dart points in the Great Basin (Bettinger and Eerkens 1999). Although the Bettinger and Eerkens (1999) study was based on western Great Basin projectile points, physical requirements and limitations of dart versus arrow points logically apply to all geographic areas. The application of these measures on the California coast cannot be considered definitive, but there are relationships between weight and CHC 1-93 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 52 neck width in distinguishing arrow from dart points. The point is morphologically most similar to the Houx Contracting Stem point type in the Coastal Contracting Stem Cluster (Justice 2002:265-269) or the Gypsum point type in the Gypsum Cluster (Justice 2002:290-298). Neither of these categories ideally fits the projectile point recovered from SLR-S-1. The point does not exhibit pressure flaking, which is a common attribute of both Houx and Gypsum points, and Justice (2002) does not provide metric attributes with which to compare the specimen. Bifaces The artifact assemblage includes ten bifaces recovered from the site surface and excavation units. By provenience, they consist of eight bifaces from the site surface (00-00-06, 00-00-07, 00- 00-11, 00-00-26, 00-00-27, 00-00-33, 00-00-57, and 00-00-60) and two from STP 1 (30-02-06 and 30- 02-07). All of the bifaces were manufactured through percussion reduction from opaque CCS. The majority exhibit non-patterned flake scars and plano-convex cross-section shapes, while two exhibit a chevron flake scar pattern and flat cross-section shapes. Six of the bifaces are manufactured from Franciscan chert, while four are made from indeterminate CCS toolstone. The bifaces are evenly distributed along the reduction continuum. None exhibit pressure flaking, and the majority (n=7) are fragmented. Five of the fragmented bifaces exhibit perverse breaks, one exhibits both one perverse break and one bending break, and one exhibits only a bending break. Perverse fractures are most common during stone tool manufacture so that their combined relative frequency of 86 percent should be considered a significant indicator of on-site biface manufacture (Figure 7). Eight of these bifaces were manufactured on flake blanks, while one was manufactured from a core, and one is indeterminate. Figure 7. Pie chart displaying the breaks present on the SLR-S-1 fragmented bifaces. Edge Modified Flake One edge-modified flake made from opaque dark reddish brown Franciscan chert was recovered from the site surface. Light, continual, and non-intrusive percussion flaking is present along the majority of one face of one margin. Cores The core assemblage includes three assayed cobbles, four complete cores, and two core fragments. Core reduction patterns identified in the assemblage include informal, Perverse 72% Bending 14% Both 14% CHC 1-94 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 53 multidirectional assayed cobbles and cores and one formal, bidirectional core. These reduction patterns are briefly defined as follows. Multidirectional cores exhibit flake removals taken from more than one striking platform (Andrefsky 2007: 16, 82, 145). Multidirectional cores without patterning are considered informal. Informal cores exhibit opportunistic flake removals from numerous directions, multiple platforms, and on several faces of the objective piece. Multidirectional cores can exhibit patterning; patterned flake removal can produce flakes of similar proportions and can maximize the number of flakes that can be removed from the core. Bidirectional cores exhibit flake removals from only two directions and are considered formal. Andrefsky (2007) explains that no comprehensive method for the comparison of core size and type has been developed, but proposes a method to compare the size class of cores. Andrefsky’s (2007:145-147) formula for calculating size value to explore potential patterning between core size and type is used for the CA-SLO-2825 assemblage. The size value of a core is the product of the maximum linear dimension multiplied by the weight of the core. The cores in the present assemblage are all made from locally-derived cryptocrystalline silicate sources, including the Franciscan Complex and the Monterey Formation (Bertrando and Harro 1997). Andrefsky (2007) postulates that cores made from higher quality toolstone will be formally reduced and tend to be exhausted. For example, high quality, non-local toolstone, such as obsidian, will tend to be formally reduced. Formal reduction and reuse extends the use of a single piece of high quality toolstone. Moreover, specimens of high quality toolstone left behind by previous occupants, such as obsidian flakes or bifaces, may be curated (collected, reworked, and/or reused) by later groups (Whittaker 1994:264). Locally available, lower quality toolstone, however, will tend to be informally reduced and discarded prior to exhaustion. Consequently, the average size value for patterned, formally reduced cores of high quality, non-local toolstone will tend to be smaller than the non-patterned, informally reduced and often easily discarded cores made from lower quality, locally-available toolstone. Analysis of toolstone material type and size class indicates that the CA-SLO-2825 cores have relatively similar size values, although the core classified as a bidirectional, formal core is much smaller. The average core size value (n=9) is 244.5, whereas the size value for the formal core (n=1) is 76. The flake removals as well as the size values calculated for the cores recovered from CA-SLO-2825 follow the expected pattern—non-patterned cores made from locally-derived materials are large and discarded prior to exhaustion. Debitage All debitage in the SLR-S-1 assemblage was subject to technological analysis (n=385), including debitage collected from the site surface as well as the auger tests, shovel test pits, and test unit and extracted from ⅛-inch mesh screens. The debitage classifies as 111 (29 percent) technologically diagnostic flakes and 274 (71 percent) less diagnostic debitage. Simple interior flakes (n=72, 19 percent) and simple fragments (n=214, 56 percent) dominate the assemblage. As shown in Figure 8, shatter (n=49, 13 percent) and cortical flakes (n=23, 6 percent) represent the next most frequent debitage types. These flake types, without the presence of biface thinning flakes, typically indicate early to mid-stage flaked stone reduction activities. CHC 1-95 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 54 Figure 8. Pie chart displaying the overall debitage category distribution for SLR-S-1. The flaked stone assemblage is composed entirely of cryptocrystalline silicate toolstone. The primary toolstone used to produce flaked stone artifacts was visually sourced to locally- available Franciscan and Monterey cherts. Figure 9 shows the frequency of each toolstone source represented in the flaked stone assemblage. Figure 9.

Individual, technologically relevant flakes may suggest the application of specific stone working techniques, but the relative frequency of those techniques cannot be determined from available information. For example, a late biface thinning flake indicates that late stage biface manufacture may have occurred at a site at least once. However, the spectrum of reduction stages and techniques represented by that single flake remain unknown without a much larger and temporally controlled assemblage. As such, the Phase II assemblage provides only general interpretations in the approach to stone tool manufacture at SLR-S-1. The debitage present in the assemblage comprises 111 diagnostic flakes and 274 less diagnostic pieces. The relatively small technologically diagnostic debitage sample indicates that percussion flake production is the most archaeologically visible and possibly the most common flaked stone reduction activity that took place at SLR-S-1. Relatively low frequencies of cortical debitage (6 percent) indicate that toolstone procurement and cortex removal primarily occurred off-site. The proportion of simple interior flakes (19 percent) and simple flake fragments (56 percent) to later-stage reduction flakes suggests an emphasis on flake production as the objective of stone working rather than biface manufacture at the site. The majority of the debitage is also fragmented (60 percent). If the sample had included a higher proportion of complete diagnostic flakes (e.g. complex interior, biface thinning, pressure flakes) to less diagnostic flakes and flake fragments, then the sample might more closely reflect biface thinning at SLR-S-1. Some minor formal tool production (e.g., projectile point and biface manufacture) and shaping activities are indicated by the presence of biface fragments and a projectile point. Further, roughly three-quarters of the bifaces (n=5; 72 percent) indicate on-site biface manufacture as evidenced by perverse fractures that result from manufacturing failures. Debitage in the SLR-S-1 assemblage is dominated by CCS visually sourced to two local geological formations along the central coast: the Franciscan Complex and the Monterey Formation. The CCS toolstone in the assemblage is suspected to be more readily available from regional sources (i.e., closer) rather than more distant sources, although investigation regarding the location and distribution of such sources is beyond the scope of this study. CCS sources are likely more proximate to the site than other toolstone materials (see Bertrando and Harro 1997), as the import of unreduced raw material and earlier stage cores and bifaces may be more practical from local sources such as chert from the Franciscan Complex and Monterey Formation. The comparatively high proportions of simple interior flakes and simple flake fragments suggest an emphasis on percussion flake production at SLR-S-1. 7.1.2 Isolated Artifacts P-40-038327 P-40-038327 consists of an isolated prehistoric grayish-brown cortical CCS flake measuring 4.8 x 3.6 x 1 cm (Photograph 3).

P-40-038328, plan view. 7.2 ARCHAEOLOGICAL EVALUATION Isolated finds typically do not qualify as historical resources under CEQA and thus isolates P- 40-038327 and P-40-038328 were determined ineligible for listing in the CRHR/NRHP. Rincon evaluated archaeological site CA-SLO-2825 to determine the eligibility for listing in the CRHR/NRHP. Archaeological site CA-SLO-2825 is a prehistoric surface artifact scatter with a CHC 1-98 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 57 shallow subsurface component. The artifact assemblage consists almost entirely of flaked stone tools and debitage. CA-SLO-2825 represents a lithic production location where tools were manufactured. Such locations were components of a larger procurement strategy and were likely associated with unknown temporary camps or habitation sites in the vicinity, although none were identified as part of the current study. The site is highly disturbed by repeated plowing, planting, harvesting, and other activities associated with crop cultivation. Although subsurface artifacts are present, they are limited to disturbed sediments above 40 cmbs and do not represent an intact deposit. It is likely the subsurface component consists of artifacts that were previously located on the surface scatter and have been redeposited due to remixing of sediments caused by agricultural activities. The site is not directly associated with important events or any persons significant in our past (Criteria A/1 and B/2). Criterion C/3 is not relevant to archaeological deposits of this type. Due to the absence of an intact subsurface component and lack of specific, interpretable context the site is unlikely yield important information about prehistory or history (Criterion D/4). Thus site CA-SLO-2825 is recommended ineligible for listing in the CRHR/NRHP and requires no further management consideration under CEQA or the NHPA. Due to the assemblage’s lack of association with specific people or discrete events and because the recovered artifacts have little potential to contribute to future research, Rincon recommends that no further work is needed for the recovered items, and we do not recommend their permanent curation. In lieu of curation, Rincon recommends donation of collected artifacts to a local Native American Tribe. 7.3 BUILT ENVIRONMENT RESOURCES An evaluation update of the buildings that comprise the San Luis Ranch complex, historically known as the Dalidio Ranch (P-40-04-1000), is provided in the following section. The property contains a grouping of buildings at the northwest end of the property and agricultural fields to the south and east. The ranch complex presently includes three single-family residences, a garage/shed, a smaller shed, the main barn, a large equipment storage building, a warehouse, and the former spectator’s barn (viewing stand), which was converted to farm use. A water tower that was previously recorded on the property in 1999 was not observed during the investigation for the current report. It may have been demolished since it was documented to be in very poor condition in 1999 (Figure 10).

It is irregular in plan and built in the Craftsman style (Photograph 5). It features a high pitched, front-gabled roof, with overhanging eaves and exposed rafter tails. The roof is clad in composition shingles. There is a shed dormer on the northeast side of the roof. On the southwest side a hipped roof extension covers the wrap-around porch and a cantilevered box bay window. The home is clad with shiplap and clapboard siding as well as shingles on the gable face. The primary entry is on the northwest elevation accessed via a wrap-around porch and a set of wooden steps. The porch supports are square pillars with plain bases and capitals. The single, solid wood entry door is surrounded by wood framing. An additional single entry door is east of the primary entry. At the end of the wrap-around porch, on the southwest side of the home, is a single, wooden door with a single pane of glass over two horizontal panels. The northwest elevation also contains a cantilevered three-window bay. There are decoratively carved knee braces in the gable face as well as a pair of double-hung, wooden 8/1 windows. Across the bottom of the gable is a plain horizontal band supported by carved brackets or exposed beam ends. The home has a variety of windows, including double-hung 1/1 windows, hopper windows, and fixed 14/1, 12/1 and 10/1 windows. The southwest elevation has a short railing giving the appearance of a partial widow’s walk. The majority of the southwest elevation was unpainted at the time of the site visit. There is a small addition projecting to the south. It has a shed roof with overhanging eaves and exposed, carved rafter tails, covered with composition shingle. It has a double-hung 1/1 window, fixed and casement windows. The wooden entry door has a rectangular opening with decorative brackets at each corner above two horizontal panels. A screen obscures any glazing that it may contain. The entry is accessed via a set of concrete steps. CHC 1-101 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 60 Photograph 5. Main residence, northwest elevation, view to the southeast. 7.3.2 Residence No. 2 This one-story single family home is estimated to have been built ca. 1900-1910 (Photograph 6). It is located at the northeast end of the property, near Madonna Road. It is rectangular in plan and appears to have a small addition on the east elevation as well as a shed extension on the south. The eastern addition contains a chimney. Both the main portion of the home and the addition feature medium pitched front-gabled roofs and an open eave overhang with fascia boards. The roof is clad with composite shingles. The shed extension features a nearly flat roof partially clad with corrugated panels. The home’s primary entrance is on the west elevation and features an entry door with a single light above and a single panel below. It is flanked by dual glazed sidelights. The entire entry is surrounded by wood framing. A set of three concrete steps with simple wood railings lead to the entrance. The dwelling is clad in shiplap siding. All windows were boarded at the time of evaluation, but appear to be surrounded by wood framing. The south elevation was not clearly visible due to a tall wooden fence. North of the home, against the tree line is a group of shed-like structures, the largest of which is constructed with vertical wood boards and has a variety of utility and storage double-doors. It has a shed roof covered with corrugated panels. CHC 1-102 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 61 Photograph 6. Residence No. 2, view to the east. 7.3.3 Residence No. 3 Adjacent to and east of the warehouse is a small single family home estimated to have been built in the 1960s (Photograph 7). It does not appear in 1963 aerial photography, but appears by 1989. It is roughly square in plan, clad with reverse board and batten and has a side-gabled roof clad with composition shingles. There are horizontally slatted vents under the gable peaks. The home features aluminum sliding windows surrounded by wood framing on the north and east elevations. The primary entry on the north elevation is a wooden, four-panel entry door. The south elevation was largely obscured by a fence and vegetation but a shed roof was noted to be attached across the width of the residence. It is supported by wood posts with Y braces and is clad with corrugated panels. The west elevation is very close to the warehouse and has no fenestration.

Residence No. 3, view to the south. 7.3.4 Garage/Shed Situated south of the shed discussed below is a larger shed or garage (Photograph 8). Estimated to have been built in the 1930s, it is rectangular in plan and is clad with flush, vertical wooden boards. It is covered with a shed roof that has exposed rafter tails and is clad with corrugated metal panels. The eastern half of the shed has wood flooring and contains large openings on both the north and south elevations that align so vehicles or equipment can pass through the building. The western half of the shed contains a similar opening on the north elevation.

Garage/shed, northwest elevation, view to the southeast. 7.3.5 Shed No. 2 Situated directly south of the primary dwelling is a small rectangular shed (Photograph 9). Estimated to have been built in the 1930s, it is clad with vertical wooden boards and has a shed roof clad with corrugated panels. The east elevation contains a square window opening covered with mesh wire. The north elevation contains a centered, arched opening and an additional single entry door, which is wooden with horizontal slats. A wooden fence is attached to and projects off the southern elevation. CHC 1-105 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 64 Photograph 9. Shed No. 2, northwest elevation, view to the southeast. 7.3.6 Main Barn To the west of the primary dwelling is a raised-center-aisle barn estimated to have been built in 1900 per the county assessor records (Photograph 10). It is clad with vertical wooden boards. The roof is clad with corrugated metal panels. The north elevation has a large centered opening with chamfered corners as well as a sliding barn door. The south elevation has a sliding barn door and a large hinged door, as well as a hay carrier and hay doors under the gable peak. The east elevation features four open bays supported by square wooden posts. There is no fenestration on the west elevation. The barn is situated near Madonna Road at the northwest end of the property.

It is estimated to have been built in 1938 per the county assessor records. It has a rectangular footprint and has four open bays on one side. The building is clad with vertical wooden boards. The shed roof is covered with corrugated aluminum panels and is supported by poles that appear to be salvaged utility poles, enhanced with Y braces. CHC 1-107 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 66 Photograph 11.

It does not appear in 1963 aerial photography but does by 1989. It is rectangular in plan and is clad with vertical aluminum panels. It has a very low pitched, gabled roof. The east elevation features a single entry door (possibly metal), as well as a metal roll-up garage door and a rectangular vent with horizontal slats. The south elevation also has a metal roll-up garage door. There is no fenestration on the west elevation. Across the width of the north elevation is a shed supported by round metal poles. It has a flat roof clad with corrugated metal panels. A covered hoop house was stored beneath it at the time of evaluation.

Warehouse, east elevation, view to the southwest. 7.3.9 Former Spectators’ Barn/Viewing Stand To the southwest of the main residence is the former spectators’ barn/viewing stand that has been converted to other farm uses (Photograph 13). It is estimated to have been built ca. 1887. It is a two-story wood framed building clad with shiplap siding. It has a rectangular plan and a high pitched, side-gabled roof with boxed eaves. The northwest elevation features a strip of angled window openings that indicate the building’s prior use as a race track viewing stand - the slant is likely a result of row seating and the open seating/viewing area was likely enclosed. Beneath this are two window openings which have been boarded over. Under the gable peak is a hay carrier and a pair of hay doors on hinges. The northeast elevation features a centered entry comprised of a pair of large arched openings with chamfered edges at the top. There is also a single entry door which appears to be plyboard, accessed by three concrete steps, and an additional wooden, four-paneled, single entry door that is missing the steps leading up to it. Two rectangular window openings have been boarded over. Across approximately 1/3 of the northeast elevation there is a railing that may have once held a sliding barn door. The southeast elevation shows evidence of the same angled openings as the northwest elevation, but the openings have been closed/boarded over from the interior and painted. The shiplap siding exists only on the gable face – the lower approximately 2/3 of the building is clad with vertical boards. Attached to the southeast elevation are shed roofs of varying pitch, supported by wood posts and covered with corrugated aluminum. The southeast elevation also has a set of concrete steps and metal railings leading to a single solid entry door. Various CHC 1-109 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 68 Photograph 13. Former spectator’s barn/viewing stand, northwest elevation, view to the southeast. windows have been boarded over. A set of doors on hinges is located about halfway up the wall. A large concrete loading dock wraps around the southeast and southwest sides of the building. Along the southwest side of the building there is an addition that appears to have been constructed at a later date. It is clad with vertical wood boards and has a steeply pitched shed roof. On the southwest elevation it has six square cut window openings cut into the wood and hung on hinges like casement windows. On the north elevation it has a single door opening as well as a window that has been boarded over. Attached to the addition and projecting to the north is a slanted shed roof over a concrete platform. It is supported by square wood posts and clad with corrugated aluminum sheets. 7.4 HISTORIC EVALUATION The Dalidio Ranch is comprised of three residences, the main barn, a farm equipment storage building, a garage/shed, a warehouse, a smaller shed, and the former spectator’s barn/viewing stand. These buildings were constructed between ca. 1887 and the mid-1960s. The ranch complex retains integrity of location, design, setting, materials, workmanship, feeling and association. Despite commercial and residential development to the east and west, the property maintains integrity of setting, feeling and association due to its large size, the expanse of agricultural fields to the south and the lake site to the north, as well as the mature row of trees screening the property from the road. The main residence, main barn, and farm equipment storage building retain integrity of location, design, materials and workmanship. The main CHC 1-110 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 69 residence (a Craftsman style home) and the main (raised-center-aisle) barn retain the majority of the character-defining features associated with their style and/or construction method. The ancillary buildings such as the smaller shed and garage are vernacular in construction and may have been moved from one part of the property to another as needed for the agricultural business; however, they remained on the property and have contributed to its agricultural function. Residence No. 2 appears to have additions; oral histories relate that the building was pieced together using parts from the former spectator’s barn/viewing stand. The warehouse and residence No. 3 appear to be more recent construction estimated to be built in the 1960s. The former horse race track spectator's barn/viewing stand has been moved from its original location and repurposed for use on the farm. The building was originally located near the race track and stables, where the cultivated fields are today, south of the ranch complex. A kitchen and cocktail lounge that once existed on opposite ends of the viewing stand were removed by the Wood family. Parts of the kitchen were utilized for the construction of the original Wood family residence. A dairy and a stable were added onto the viewing stand building by the Woods. The seating in the upstairs viewing area was removed and the space was used as a hay loft. The Dalidio family subsequently removed the dairy addition that the Woods had constructed. Since the race track has not existed since approximately the year 1900 when William Wood owned the property and the viewing stand has been moved and heavily altered, the building does not retain integrity of location, design, materials, workmanship or feeling as a race track viewing stand. However, the building has been an integral component of the ranch complex since the Woods began repurposing parts of the building and converted it to a dairy, stable and hay barn. Over the years the former viewing stand has served as a utilitarian agricultural building on the ranch property. The Dalidio Ranch appears eligible for listing in the CRHR as a property, under Criteria 1 and 3. It also appears eligible for designation as a City of San Luis Obispo landmark property (B.2 and B.3). The main residence and the main barn also appear individually eligible for listing in the CRHR and as City of San Luis Obispo landmark properties for their construction and design (Criteria 3 and A.1). The period of significance for the Dalidio Ranch is 1900 – 1940, or, the early part of the 20th century, when ranching and agriculture were the region’s main enterprises and influenced the development of the San Luis Obispo. William Wood and his son Forest Wood developed and operated a family farm between 1900 and approximately 1921, after which the Dalidio family acquired the property and increased agricultural production. The buildings constructed during the period of significance (residences No. 1 and No. 2, the garage/shed, shed No. 2, main barn, equipment storage building, and the former spectators’ barn/viewing stand) retain sufficient integrity to convey their importance as a property. Although the former spectator’s barn/viewing stand has been moved and altered over the years to accommodate its change in use from equestrian related activities to agriculture, the building retains sufficient integrity as a barn to convey its use and function during its subsequent use. 7.4.1 National and California Registers The San Luis Obispo Ranch appears eligible for listing in the CRHR for its association with the early agricultural development of San Luis Obispo (Criterion 1). Beginning as a family farm and expanding into a larger agribusiness, the property has retained a complex of ranch buildings CHC 1-111 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 70 and cultivated fields for over a century. The property was owned for many decades by the Dalidio family, who has been involved in the regional dairy industry and agribusiness. Their contributions are believed to be of local significance, not statewide or nationwide, thus the property is not eligible under Criterion 2. The property is representative of an early 20th century farm with its associated buildings, agricultural fields and ancillary structures. The buildings reflect the distinctive characteristics of the early twentieth century vernacular agricultural architecture (Criterion 3). The property is not expected to yield important information about prehistory or history, as part of the Dalidio property (Criterion 4). Although eligible for the CRHR, the property does not appear to demonstrate sufficient historical significance in national, state or local agricultural development or as a unique property type to warrant listing in the National Register of Historic Places (Criteria A-D) as a property or as individual resources. The main Craftsman style residence (residence No. 1) and the main barn also appear individually eligible for listing in the CRHR, as they both embody the distinctive characteristics of Craftsman and vernacular agricultural architecture (Criterion 3). The main Craftsman style residence from ca. 1910 and the main (raised-center-aisle) barn retain the majority of their character-defining features and integrity. 7.4.2 City of San Luis Obispo Designation The Dalidio Ranch property exemplifies an important period of local history, being established as a family farm and developing into a valuable local industry, agribusiness. The property is representative of the historical theme of Early 20th Century Agricultural and Industrial Development. The property is known to have been in agricultural use by the year 1900 when William Wood acquired the land, did away with the race track that existed on the property to create a grain field, and began re-purposing the race track structures for use on his farm. The Dalidio family acquired the property by the early 1920s and kept it in agricultural use, retaining buildings that the Woods had constructed and adding other structures. A complex of farm buildings and cultivated fields has existed on the property for over a century. The Dalidio Ranch is a rare remaining and intact example of a farm complex representing the early agricultural history of San Luis Obispo. Therefore it is eligible for designation as a City of San Luis Obispo historic resource under criterion B.2 (Event) and B.3 (Context). Besides embodying an early 20th century farm complex when assessed as a whole, individual buildings on the Dalidio Ranch also embody distinctive characteristics of a type, period, region, or method of construction. The main residence is constructed in a Craftsman style and retains many of its character-defining features such as clapboard and shiplap siding, shingles in the gable face, overhanging eaves and exposed rafter tails, decoratively cut knee braces and rafter tails, a wrap-around porch supported by square pillars, a shed-roofed dormer window, and various original wood windows. The main barn also embodies the raised-center-aisle type of barn. It retains its barn doors, hay doors, hay carriers and hardware, thus retaining much of its integrity. The main residence and main barn are therefore eligible for designation as City of San Luis Obispo historic resources under criterion A.1 (Style). CHC 1-112 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 71 8.0 PROJECT IMPACTS AND RECOMMENDATIONS The CEQA Guidelines state that a project may have a significant effect on the environment if it can be expected to “cause a substantial adverse change in the significance of an historical resource” (CEQA Guidelines, Section 15064.5 (b)). Such changes can include physical demolition, destruction, relocation, or alteration of a historical resource or its immediate surroundings such that the significance of an historical resource would be materially impaired. If it can be demonstrated that a project will cause damage to a unique archaeological resource, the lead agency may require reasonable efforts be made to permit any or all of these resources to be preserved in place or left in an undisturbed state. To the extent that they cannot be left undisturbed, mitigation measures are required (Section 21083.2[a], [b], and [c]). 8.1 ARCHAEOLOGICAL RESOURCES Rincon identified and recorded one prehistoric archaeological site (CA-SLO-2825) and two prehistoric isolated artifacts (P-40-038327 and P-40-038328). Under CEQA, isolates are not eligible for listing in the CRHR. Archaeological site CA-SLO-2825 has been found not eligible for listing in the CRHR and NRHP, and it is not a unique archaeological resource. The information potential of site CA-SLO-2825 and isolates P-40-038327 and P-40-038328 has been exhausted by their recordation and analysis as part of the current study, and relevant site records will be submitted to the CHRIS information center. As such, disturbance of these resources would not constitute a significant impact under CEQA. 8.1.1 Archaeological Resources Mitigation Measures All archaeological resources identified in the project site have been found ineligible for listing in the CRHR/NRHP. The surface of the project site has been previously disturbed by 100 years of agricultural activities including planting, harvesting, and other activities associated with crop cultivation and thus the possibility of encountering undisturbed archaeological resources during construction is unlikely. Rincon recommends implementation of the following measures to reduce potential impacts to previously unidentified archaeological resources. CR MM-1 Retain a Qualified Principal Investigator A qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology, shall be retained to carry out all mitigation measures related to archaeological and historical resources (hereafter qualified archaeologist). CR MM-2 Unanticipated Discovery of Archaeological Resources In the event that archaeological resources are exposed during construction, work in the immediate vicinity of the find must stop until a qualified archaeologist can evaluate the significance of the find. Construction activities may continue in other areas. If the discovery proves significant under CEQA (Section 15064.5f; PRC 21082), additional work such as testing or data recovery may be warranted. CHC 1-113 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 72 CR MM-3 Unanticipated Discovery of Human Remains The discovery of human remains is always a possibility during ground disturbances; State of California Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. The County Coroner must be notified of the find immediately. If the human remains are determined to be prehistoric, the Coroner will notify the Native American Heritage Commission, which will determine and notify a Most Likely Descendant (MLD). The MLD shall complete the inspection of the site within 48 hours of notification and may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials. 8.2 ARCHAEOLOGICAL RESOURCES LEVEL OF SIGNIFICANCE AFTER MITIGATION Implementation of mitigation measures CR MM-1 through CR MM-3 would reduce impacts to archaeological resources to a less than significant level. 8.3 BUILT ENVIRONMENT/HISTORIC RESOURCES Rincon Consultants finds that the Dalidio Ranch complex (main residence, secondary residence, main barn, equipment storage building, garage/shed, shed No. 2, and former race track spectators’ barn/viewing stand) is eligible for listing in the CRHR and as a City landmark. Further, residence No. 1 and the main barn are also considered individually eligible for the CRHR and as a City landmark. These properties are considered historical resources under CEQA. According to CEQA (Section 21084.1) a project that may cause a substantial adverse change in the significance of an historical resource is a project that may have a significant effect on the environment. Substantial adverse change is defined as demolition, destruction, relocation, or alteration activities that would impair the significance of the historic resource. A project that has been determined to conform with the Secretary of the Interior’s Standards for the Treatment of Historic Properties can generally be considered to be a project that will not cause a significant impact (14 CCR Section 15126.4(b)(1)). In most cases where a project meets the Secretary of Interior’s Standards for the Treatment of Historic Properties, it can be categorically exempt from CEQA (14 CCR Section 15331). Relocation of an historical resource may also constitute an adverse impact to the resource. However, in situations where relocation is the only feasible alternative to demolition, relocation may mitigate to below a level of significance provided that the new location is compatible with the original character and use of the historical resource and the resource retains its eligibility for listing on the California Register (14 CCR Section 4852(d)(1)). As currently proposed, the project would result in the relocation and adaptive reuse of the main residence (residence No. 1) and former spectators’ barn/viewing stand to another part of the site, and the demolition or off-site relocation of the remaining buildings and structures on the ranch, thus eliminating the historic district. The relocation, demolition and off-site relocation of CHC 1-114 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 73 buildings and structures comprising the Dalidio Ranch historic district would constitute a significant direct impact to cultural resources related to a substantial adverse change in the significance of historical resources. 8.3.1 Built Environment/Historic Resources Mitigation Measures Although not capable of reducing impacts to below the level of significance, three mitigation measures have been identified that would reduce project impacts on historical resources to the maximum extent practicable. These are listed below. CR MM-4 A relocation plan should be developed and implemented for the main Craftsman residence (residence No. 1) and the former race track spectators’ barn/viewing stand. The comprehensive relocation plan should include a structural/architectural condition and feasibility assessment to provide the necessary existing conditions data required to substantiate the relocation. If relocation is found feasible, the plan should identify a suitable relocation site that is compatible with the existing setting of the property; such as the proposed project’s agricultural center. The plan must also include detailed measures that demonstrate that the buildings will retain their historic significance following their relocation. Completion of this mitigation measure shall be monitored and enforced by the City of San Luis Obispo. CR MM-5 Impacts resulting from the demolition and relocation of the buildings shall be minimized through archival documentation of the entire historic building complex in as-built and as-found condition. Prior to issuance of demolition permits, the lead agency shall ensure that documentation of the buildings and structures proposed for demolition is completed in the form of a Historic American Building Survey (HABS) Level II documentation that shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990). The documentation shall include large-format photographic recordation, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). The original archival-quality documentation shall be offered as donated material to the History Center of San Luis Obispo County where it will be available for current and future generations. Archival copies of the documentation also would be submitted to the San Luis Obispo County Library where it would be available to local researchers. Completion of this mitigation measure shall be monitored and enforced by the City of San Luis Obispo. CR MM-6 Impacts related to the loss of the Dalidio Ranch complex shall be reduced through the development of a retrospective interpretive display detailing the history of the project site, its significance, and its important details and features. The information can be incorporated into a publicly-accessed building on the project site or a publicly-accessed outdoor location. The display shall include images and details from the HABS documentation and any collected research pertaining to the historic property. The content shall be prepared by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). The display shall CHC 1-115 Attachment 2 San Luis Ranch Project Cultural Resources Survey and Evaluation City of San Luis Obispo 74 be completed within one year of the date of completion of the proposed project. Completion of this mitigation measure shall be monitored and enforced by City of San Luis Obispo. 8.4 BUILT ENVIRONMENT/ HISTORIC RESOURCES LEVEL OF SIGNIFICANCE AFTER MITIGATION Implementation of mitigation measures CR MM-5 and CR MM-6 would reduce significant direct and cumulative impacts to historical resources scheduled for demolition to the maximum extent feasible. However, the demolition of these historical resources would still remain a significant adverse impact. Implementation of mitigation measure CR MM-4 would reduce impacts to the main Craftsman residence (residence No. 1), former race track spectators’ barn/viewing stand to the maximum extent feasible, however demolition or removal of the remaining buildings and structures comprising the Dalidio Ranch historic district would still result in a significant direct impact to the property as a whole and result in cumulative impacts.

The absence of specific site information in the sacred lands file does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites. Enclosed is a list of Native Americans individuals/organizations who may have knowledge of cultural resources in the project area. The Commission makes no recommendation or preference of a single individual, or group over another. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated, if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe or group. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from any of these individuals or groups, please notify me. With your assistance we are able to assure that our lists contain current information. If you have any questions or need additional information, please contact me at (916) 373-3712.

(Rincon) is preparing environmental documentation for the proposed San Luis Ranch Project (project) for the City of San Luis Obispo. The project consists of a Specific Plan, General Plan Amendment, and Development Plan for the 131-acre project site, including annexation of the project site into the City of San Luis Obispo (City). The site is currently located in unincorporated San Luis Obispo County and is identified by assessor’s parcel number 067-121-022.

As part of the process of identifying cultural resources issues for this project, Rincon contacted the Native American Heritage Commission and requested a Sacred Lands File (SLF) search and a list of Native American tribal organizations and individuals who may have knowledge of sensitive cultural resources in or near a nearby project area. Rincon is consulting with you directly regarding your knowledge of the presence of cultural resources that may be impacted by this project.
