FROOM RANCH PROJECT SAN LUIS OBISPO COUNTY, CALIFORNIA BIOLOGICAL RESOURCES INVENTORY Prepared for: JM Development Group, Inc. P.O. Box 5310 San Luis Obispo, California 93403 Prepared by: KMA Kevin Merk Associates, LLC P.O. Box 318 San Luis Obispo, California 93406 Revised November 2018 KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. ES-i EXECUTIVE SUMMARY Kevin Merk Associates, LLC (KMA) conducted a biological resources inventory in 2015 to support development planning efforts on the Froom Ranch located in San Luis Obispo County, California. The purpose of the study was to inventory biological resources present and characterize the existing conditions on the property. A background literature review, floristic inventory, tree inventory and special status plant and wildlife evaluations were conducted. The inventory identified special status biological resources (i.e., special status plant communities, plants and drainage features) present onsite, and provided a list of special status wildlife that could occur within the study area to support the City of San Luis Obispo’s (City) environmental review process. The 2015 study took place over the course of the winter, spring, summer and fall to delineate and characterize plant communities onsite, conduct rare plant surveys, and identify any habitat that could potentially support special status species or otherwise be of concern to the United States Fish and Wildlife (USFWS), U.S. Army Corps of Engineers (USACE or Corps), National Oceanic and Atmospheric Administration (NOAA) Fisheries (also known as National Marine Fisheries Service), California Department of Fish and Wildlife (CDFW), California Regional Water Quality Control Board (RWQCB), and the City. A Delineation of Waters of the United States and State of California (KMA, 2015) was also prepared to identify the extent of USACE, CDFW and RWQCB jurisdiction over onsite drainage features and wetlands. The proposed project is currently in the Specific Plan phase and proposes varying development across the property along with preserved open space. The project also includes a proposal to restore the Froom Creek corridor onsite to align with its historic location, keeping its current hydrologic connection to San Luis Obispo Creek. The Froom Creek restoration element also proposes to connect the realigned creek corridor with wetland habitat near Calle Joaquin. Supplemental information requested from the City’s consultant preparing the Environmental Impact Report (EIR) for the Specific Plan (project) was concerned with the potential presence of special status wildlife and impacts of the creek realignment and project development to onsite wetlands and supporting hydrology, including the proposed relocation of the Irish Hills Plaza basin offsite to the south. Due to modifications in the site development plan, the original study area was enlarged to cover land that could be affected by the proposed project. This included the addition of the Basin Study Area and a site proposed for secondary access on the Mountainbrook Church property, the potential Land Swap Study Area on City-owned property, and expansion of the original study area to include the separated Calle Joaquin wetland area to the southeast. Additional investigations on the expanded study area included a Vernal Pool Habitat Assessment (KMA, 2017) and a Site Assessment for the California Red-Legged Frog (Rana draytonii; CRLF) (KMA, 2017). Two memoranda were also prepared by KMA in 2018 to provide supplemental biological resources information requested by the City’s EIR consultant. It included a February 22, 2018 memorandum and associated maps documenting resources on areas proposed for a storm water basin (Basin Study Area), secondary access, and a potential land swap (Land Swap Study Area). Another memorandum was prepared on July 18, 2018 to provide further analysis of special status wildlife potentially occurring onsite. The information provided in the above referenced reports and memoranda is woven into this revised BRI, and the Vernal Pool Habitat Assessment and Site Assessment for the CRLF are included as appendices to this report to help support the environmental review process. Additional day and night surveys following current USFWS survey guidelines (2005) for the CRLF were also conducted, and no CRLF were detected onsite. To complement and reinforce the hydraulic and hydrologic reports prepared for the project, the BRI was revised to include further discussion about the potential affects the creek realignment would have on wetland resources, the history, purpose and maintenance of existing and past onsite detention KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. ES-ii basins, and the proposed offsite basin’s affects to Froom Creek and associated vegetation. Further detail is provided in Appendix G. As stated above, prior to any field work, background literature review of past biological studies conducted in the region and environmental documents from projects onsite and in the immediate area was conducted. The background review also included more recent studies prepared for the project such as the Groundwater Impacts Assessment prepared by Cleath-Harris Geologists, Inc. (September 21, 2018) and Irish Hills Plaza Stormwater Basin Maintenance Record prepared by RRM Design Group (September 10, 2018). The California Natural Diversity Data Base (CNDDB) maintained by the CDFW was queried during the course of the investigations to compile a list of special status resources known to occur in the area that could potentially be present onsite. The field efforts mapped onsite habitat types, characterized drainage features, and identified all plants within the study area to a sufficient level to determine their respective rarity status. For special status wildlife, a habitat suitability analysis was used to determine the species that could potentially occur within the study area, and focused assessments for vernal pool branchiopods and the federal threatened CRLF were completed. As stated above, protocol-level surveys for CRLF were also conducted, and no CRLF were observed in the study area . The following findings were gathered in the report: Existing Conditions. The initial study area covered the approximate 109.7 acre project site, comprised of a former working cattle/horse ranch, an active red rock quarry, and various buildings and developed areas. As part of the supplemental work, the study area was expanded to include portions of the Mountainbrook Church property; one area for construction of a storm water basin and another for secondary access. Additional area below the 150-foot topographic contour line was also included on neighboring City owned property for a potential land swap. A separated wetland area on the Froom Ranch property, southeast of Calle Joaquin outside the proposed development area, was also included in the expanded study area to characterize wetland habitat in the area. The study area supports primarily grassland habitat (a combination of native bunchgrass, non-native annual and introduced perennial grasslands). Oak woodlands, coastal scrub/chaparral, and serpentine outcrops were identified within the study area. Froom Creek and three tributary drainages are also present on the Froom Ranch property, and a fourth drainage feature is present along the southern perimeter of the Basin Study Area. Froom Creek is a tributary to San Luis Obispo Creek located offsite to the southeast. A site location map, aerial overview map, soils map, habitat map , tree survey map, CNDDB botanical occurrences map, special status plant occurrences map, and CNDDB wildlife occurrences map are provided herein. A list of plant and animal species observed, special status species known to occur in the region and an evaluation of their potential to occur onsite, a photo plate, and tree inventory data are included as appendices. Supplemental reports and basin information identified above are also included as appendices. Special Status Biological Resources. The site contains Froom Creek and associated tributary drainages. The upper elevation areas in the southwest part of the site have serpentine derived soils and rock outcrops. Grasslands in the southwest part of the study area contain native species such as purple needlegrass (Stipa pulchra), and were mapped as serpentine bunchgrass grassland separated from the annual grassland that forms the dominant cover onsite. Other special status resources onsite include coast live oak/California bay woodland, and wetland and riparian habitat associated with the drainage features. In addition, wetlands were delineated along Calle Joaquin and Los Osos Valley Road where surface and subsurface hydrology has been impounded by existing roads and adjacent development. Shallow groundwater also appears to support the wetland habitat in this area as detailed in the background reports reviewed for this project. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. ES-iii The floristic inventory identified the following special status plants occurring in the serpentine bunchgrass grassland, wetlands and on scattered serpentine outcrops in the southwest part of the site: • Blochman's dudleya (Dudleya blochmaniae; CRPR 1B.1); • Brewer's spineflower (Chorizanthe breweri; CRPR 1B.3); • Cambria morning glory (Calystegia subacaulis ssp. episcopalis; CRPR 4.2); • Chaparral ragwort (Senecio aphanactis; CRPR 2.2); • Chorro Creek bog thistle (Cirsium fontinale var. obispoense; federal and state endangered and CRPR 1B.2); • club hair mariposa lily (Calochortus clavatus ssp. clavatus CRPR 4.3); • Congdon's tarplant (Centromadia parryi ssp. congdonii; CRPR 1B.1); • Eastwood’s larkspur (Delphinium parryi ssp. eastwoodiae; CRPR 1B.2); • Jones's layia (Layia jonesii; CRPR 1B.2); • mouse-gray dudleya (Dudleya abramsii ssp. murina; CRPR 1B.2); • Palmer’s spineflower (Chorizanthe palmeri: CRPR 4.2); • San Luis mariposa lily (Calochortus obispoensis; CRPR 1B.2); and • San Luis Obispo owl's-clover (Castilleja densiflora ssp. obispoensis; CRPR 1B.2). CRPR 4 (watch list) species such as Cambria morning glory and Palmer’s spineflower were not specifically mapped like the CRPR 1B species since they were common associates occurring in the grasslands on thin soils and rock outcroppings in the southwestern project area. These species occur throughout the project region, and are small components of much larger populations in the Irish Hills and the proposed project would not jeopardize their continued existence in the area or onsite. No rare animals were observed onsite during the field surveys, but based on a habitat suitability analysis, the following special status animals were identified as having a moderate or high likelihood of occurring in specific areas of the study area: • American badger (Taxidea taxus; species of special concern) • California horned lark (Eremophila alpestris actia; watch list); • Cooper’s hawk (Accipiter cooperi; watch list); • Hoary bat (Lasiurus cinereus; special animal); • Loggerhead shrike (Lanius ludovicianus; species of special concern); • Pallid bat (Antrozous pallidus; species of special concern); • San Diego woodrat (Neotoma lepida intermedia; species of special concern); • Steelhead trout (Oncorhynchus mykiss irideus; federal threatened and species of concern); • Townsend’s western big-eared bat (Corynorhinus townsendi townsendi; species of special concern); • Tricolored blackbird (Agelaius tricolor; candidate species and species of special concern); • Western mastiff bat (Eumops perotis californicus ; species of special concern); • Western red bat (Lasiurus blossevilli; species of special concern); • White-tailed kite (Elanus leucurus; CDFW Fully Protected); and • Yuma Myotis (Myotis yumanensis; special animal).

The purpose of the investigation was to provide baseline information of the biological resources present or potentially present on the site for future development planning and review by the project team and the City of San Luis Obispo. The site is located in the eastern flank of the Irish Hills of the San Luis Range just north and west of Highway 101, and west of Los Osos Valley Road (please refer to Figures 1 and 2). The subject property is bounded by the Irish Hills Plaza to the north, Los Osos Valley Road (LOVR) to the east, the City of San Luis Obispo Irish Hills Natural Reserve to the west, and Mountainbrook Church and several hotels along Calle Joaquin to the south. The Froom Ranch had a long history as a working ranch composed of a diverse array of coastal habitats including annual and perennial grasslands, coastal scrub, chaparral, oak and bay woodland, riparian and wetland creating a mosaic of plant communities across the landscape. The region is characterized as a Mediterranean climate with mild, wet winters and warm, dry summers. Due to the site’s proximity to the Pacific Ocean, daily temperatures do not fluctuate as much as the County’s interior northeast of the Santa Lucia Mountains. Average annual temperatures range from approximately 41 degrees Fahrenheit (F) to 71 degrees F, and annual precipitation in the San Luis Obispo area ranges from approximately 21 to 24 inches depending on location (Western Regional Climate Center and National Oceanic and Atmospheric Administration, 2015). Most of the rain occurs between November and March with a small amount attributed to coastal fog and monsoonal flow during the summer months. The biological resources inventory was prepared at the request of the JM Development Group, Inc. to identify plant communities, plants and wildlife present or potentially present on the property that could be of special regulatory importance. In addition, a delineation of waters of the United States and State of California was conducted onsite (KMA 2015), and the report was reviewed by the U.S. Army Corps of Engineers (USACE or Corps). Based on field and office review of the delineation report, the USACE confirmed the wetland delineation maps identified the extent of their Clean Water Act jurisdiction on the Froom Ranch study area (letter from USACE Regulatory Project Manager, Erin M. Hanlon, to Mr. John Madonna dated September 24, 2015). This BRI report was updated in November 2018 to combine supplemental analysis and additional studies into one document. As such, the 2018 BRI includes an enlarged study area compared to the 2015 investigation. The study area now covers portions of the neighboring Mountainbrook Church property for potential construction of a storm water basin and secondary access. It also includes a roughly three acre area on City-owned land that was evaluated as a potential land swap, and a part of the applicant’s property to the southeast of Calle Joaquin that is not proposed for development. 2.0 METHODS 2.1 Background Literature Review Prior to conducting field work, KMA biologists reviewed pertinent background information from the general area. This included the review of past studies conducted by KMA and other biological consultants in the region and on the project site. Portions of the study area and surrounding lands have been subject to various biological studies, and several Environmental Impact Reports prepared for nearby development projects (i.e., Home Depot and Costco) were also reviewed. Surrounding development projects included wetland delineations and some focused biological ^_ Site Location Froom Ranch Figure 1.1 inch = 10,000 feet ^_ Site Location 0 100 20050Kilometers JM Development Group, Inc.Site Location Source: Esri 2018 Hwy-101Madonna RdL o s O s o s V a l l e y R d Froom Ranch JM Development Group, Inc.

In some instances, the focused studies included the northern and eastern parts of the BRI study area (i.e.: Home Depot/Irish Hills Plaza and Calle Joaquin Improvement projects). Hydrologic studies and wetland mitigation plans and subsequent mitigation monitoring reports were also prepared for the Home Depot/Irish Hills Plaza, and were reviewed as part of the investigation. Clean Water Act permitting for the Home Depot project, and subsequent regulatory actions taken by the USACE for permit violations during the construction of Home Depot resulted in a settlement agreement (e.g., Consent Decree dated August 12, 2002) between the former owner of the property and the USACE. The consent decree required all wetland mitigation occur offsite at the Boysen Ranch as detailed in the 2002 Wetland Restoration and Mitigation Plan relating to the Froom Ranch/Home Depot Project prepared by Olberding Environmental. Based on review of the mitigation efforts to date detailed in a Year 5 Mitigation Monitoring Report (Olberding, 2007), the USACE confirmed mitigation requirements were met, and has since resolved the consent decree with the Madonna Construction Company (letter from USACE Senior Project Manager, Crystal Huerta, to Mr. Clint Pearce of Madonna Construction Company on February 19, 2015). The following documents (or various sections of the document) were reviewed as part of the existing conditions characterization: • Madonna Eagle Hardware Environmental Impact Report (Morro Group, 1998) –the Biological Resources section, Wetland Delineation included as Appendix G and the results of Congdon’s tarplant survey were reviewed to help characterize the environmental setting of project site; • Biological Resources Analysis Letter of Findings for the Los Osos Valley Road Improvement Project (Olberding Environmental, 2001) – reviewed to help characterize the environmental setting of the project site; • Wetland Restoration and Mitigation Plans Relating to the Froom Ranch/Home Depot Project (Olberding Environmental, 2002) – the revised June 2002 version was the final document approved by the USACE and was reviewed to characterize the extent of impacts to wetlands from the Home Depot project and resulting offsite wetland mitigation requirements at the Boysen Ranch; • Year 1 Wetland Monitoring Report for the Froom Ranch/Boysen Ranch Mitigation Sites (Olberding Environmental, 2003) – this report documents the as-built condition of the Boysen Ranch offsite mitigation area; • Year 5 Wetland Monitoring Report for the Froom Ranch/Home Depot Site (Olberding Environmental, 2007) – report documents success of wetland mitigation efforts at Boysen Ranch; • Calle Joaquin Realignment Wetland Delineation (Morro Group, 2004) – reviewed to evaluate previously mapped wetlands in relation to the realignment of Calle Joaquin; • Irish Hills Plaza II Wetland Delineation Map (Morro Group, 2004) - reviewed to evaluate previously mapped wetlands on and adjacent to the site; • Froom Ranch Wetland Assessment (Morro Group, 2005) – reviewed to evaluate previously mapped wetlands onsite. Map showed no wetland area north of entrance driveway and mis-identified the precise location of the restored swale at former stockpile area impacted during construction of Home Depot; • Hydrologic Monitoring Plan for Sustaining a Separated Wetland Near Calle Joaquin (Balance Hydrologics, 2005) – reviewed to help characterize and understand the hydrology supporting the wetland area in this portion of the site; KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 5 • Irish Hills Plaza Detention Basin Report (Wallace Group, 2006) – reviewed to confirm the detention basin was constructed to handle all storm water flows from the Irish Hills Plaza and was sited to avoid impacts to potentially jurisdictional wetlands; • Los Osos Valley Road/U.S. 101 Interchange Improvements Project Biological Assessment for Central California Coast Steelhead (2008) – reviewed to help characterize the environmental setting of the project site and assist with the special status wildlife analysis; • San Luis Obispo Creek Watershed Enhancement Plan (Land Conservancy of San Luis Obispo County, 2002) – reviewed watershed and special status species information as well as restoration efforts to help characterize the environmental setting of the project site and support the special status species analysis; • Irish Hills Natural Area Conservation Plan Update (City of San Luis Obispo, 2011) – reviewed to help characterize environmental setting of the project site and assist with habitat mapping and special status plant and wildlife analysis ; • Irish Hills Plaza Stormwater Basin Maintenance Record (RRM Design Group; 2018) – reviewed to understand maintenance requirements and obligations for the onsite basins; and, • Froom Ranch Development Groundwater Impacts Assessment (Cleath-Harris Geologists, Inc.; 2018) – reviewed to assess potential project-related impacts to the Calle Joaquin wetland from changes in groundwater fluctuation. The California Natural Diversity Database maintained by the California Department of Fish and Wildlife (reviewed in 2015 for the initial study, then again in 2016, 2017 and 2018 for the supplemental work; CNDDB) was searched for special status biological resources documented within the United States Geological Survey’s (USGS) 7.5-minute topographic quadrangle maps (quads) centered on and surrounding the site. This included the Morro Bay South, San Luis Obispo, Lopez Mtn., Port San Luis, Pismo Beach and Arroyo Grande NE quads. Given the project site’s proximity to the Pacific Ocean and geographic setting within the San Luis Range in close proximity to San Luis Obispo, the focus on these six quads was deemed a sufficient search area to identify special status species occurring in the vicinity of the site for inclusion in the study. A larger search radius picks up a number of plants and animals known from higher elevations in the Santa Lucia Mountains and further south in the Callendar and Guadalupe Dunes that would not be expected to occur on this site based on the lack of suitable habitat, soils and range restrictions. The Natural Resources Conservation Service (NRCS) Web Soil Survey was reviewed to determine the soil mapping units present within the study area (U.S. Department of Agriculture 2015 and 2018). The U. S. Fish and Wildlife Service’s online Wetland and Critical Habitat Mapper (http://www.fws.gov/wetlands/Data/Mapper.html; http://criticalhabitat.fws.gov/crithab/) were also reviewed to evaluate wetlands, drainage features and designated critical habitat defined in the region. 2.2 Special Status Biological Resources Definition For the purpose of this report, special status species are those plants and animals listed, proposed for listing, or candidates for listing as Threatened or Endangered by the U.S. Fish and Wildlife Service (USFWS) under the federal Endangered Species Act (ESA); those listed or proposed for listing as Rare, Threatened, or Endangered by the California Department of Fish and Wildlife (CDFW) under the California Endangered Species Act (CESA); animals designated as “Species of Special Concern,” “Fully Protected,” or “Watch List” by the CDFW; and plants occurring on California KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 6 Rare Plant Rank (CRPR) 1, 2, 3 and 4 developed by the CDFW working in concert with the California Native Plant Society (CNPS). The specific code definitions are as follows: • Rank 1A = Plants presumed extinct in California; • Rank 1B.1 = Rare or endangered in California and elsewhere; seriously endangered in California (over 80% of occurrences threatened/high degree and immediacy of threat); • Rank 1B.2 = Rare or endangered in California and elsewhere; fairly endangered in California (20-80% occurrences threatened); • Rank 1B.3 = Rare or endangered in California and elsewhere, not very endangered in California (<20% of occurrences threatened or no current threats known); • Rank 2 = Rare, threatened or endangered in California, but more common elsewhere; • Rank 3 = Plants needing more information (most are species that are taxonomically unresolved; few species on this list meet the definitions of rarity under CEQA); and • Rank 4.2 = Plants of limited distribution (watch list), fairly endangered in California (20-80% occurrences threatened, seldom meets the definition of rarity under CEQA). • Rank 4.3= Plants of limited distribution (watch list), not very endangered in California (seldom meets the definition of rarity under CEQA). While CRPR 4 (watch list) species were included in the special status species definition used for this study, watch list species typically do not meet the CEQA rarity definition in Section 15380 since they occur over much larger areas than CRPR 1 and 2 species. Sensitive or special status natural communities are those plant communities listed as rare in the CNDDB queried during project analysis. In addition, those habitat types or plant communities that have special regulatory status such as riparian and wetland habitats protected by California Fish and Game Code or the Clean Water Act are also identified as special status biological resources. 2.3 Field Surveys Kevin Merk and Robert Sloan were the primary investigators for all field work associated with the biological resources inventory in 2015. Additional field support was provided by KMA staff, Mr. Jaryd Block in 2015. Surveys were conducted on multiple days through the winter, spring, summer and fall of 2015. In addition, Mr. Merk conducted multiple site visits prior to, during and immediately following winter rain events during 2013/2014 to evaluate and characterize onsite wetlands to support the delineation of waters of the United States and state of California prepared by KMA in August 2015. A focused tree survey, a full floristic inventory, and a wildlife habitat assessment were conducted on the site. Supplemental analysis prepared by KMA in 2017 included a Vernal Pool Habitat Assessment and Site Assessment for the California Red-Legged Frog (Rana draytonii), which are included as appendices to this report. The following table provides the date and personnel for each survey conducted in 2015: KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 7 Table 1. 2015 Survey Dates and Personnel. Survey Date Survey Personnel January 28, 2015 Merk, Sloan, Block February 10, 2015 Sloan, Block March 3, 2015 Merk, Sloan March 11, 2015 Merk, Sloan, Block March 20, 2015 Merk, Sloan April 3, 2015 Merk, Sloan April 24, 2015 Merk May 22, 2015 Sloan June 1, 2015 Merk, Sloan June 19, 2015 Merk July 21, 2015 Merk, Sloan August 19, 2015 Merk September 17, 2015 Merk October 15, 2015 Merk The entire Froom Ranch property was included in the 2015 study, and the study area was enlarged to cover the additional areas referenced above in 2016, 2017, and 2018. Numerous other site visits occurred following the 2015 study. During the focused surveys in 2015, the study area was traversed on foot with special attention given to the drainage features, wetlands, native grasslands and serpentine rock outcrops. Extensive time was spent onsite, especially in the lower elevation grasslands along Los Osos Valley Road and Calle Joaquin, to delineate the extent of federal and state jurisdictional wetlands and other waters (please refer to KMA’s Delineation of Waters of the United States and State of California prepared in August 2015 for further information). Existing plant communities were initially mapped on an aerial photograph obtained from Google Earth and ESRI, both from 2015. Subsequent surveys and this revised report utilized more recent aerial imagery from 2017. Serpentine bunchgrass grassland was identified based on the dominant cover of native bunchgrasses and forb associates, and then delineated with a Trimble GPS unit. Historic aerial imagery obtained from Google Earth (dating back to 1994) was also utilized to assess plant community distribution onsite during field surveys. Photographs of notable features including special status plants were also taken to document existing conditions of the study area. 2.4 Tree Inventory KMA Senior Biologist Robert Sloan with field support from Jaryd Block and Kevin Merk conducted an inventory of trees within the Froom Ranch property on February 10 and March 3, 2015. The survey covered the entire Froom Ranch property. Trees on the steep western hillside area were not tagged due to access and dense poison oak. All other trees located within the property with a diameter at breast height (about 4.5 feet above grade; DBH) of approximately four (4) inches or greater were identified, measured, tagged, and evaluated during the inventory. Tags consisted of aluminum disks numbered 1 through 96, and were attached with aluminum nails to the east side of the main trunk. The locations of all tagged trees were recorded with a Trimble GPS unit. Willow shrubs/trees along LOVR that were four inches DBH or greater were not tagged, but were counted and generally evaluated for health or vigor. Similarly, riparian scrub and ornamental trees (both eucalyptus and Monterey cypress) present on the Basin Study Area were not included in the tree inventory. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 8 Basic tree characteristics and physical conditions were evaluated for each tagged tree, and overall health was evaluated based on vigor, presence of damage (i.e. pathogens, insect pests, and other forms of natural and human-caused damage), and comparison to the typical archetype of the same species. Field evaluations of all trees considered the following attributes: Trunk diameter – The diameter of the trunk of each tagged tree was measured at approximately 4.5 feet above grade using a forester’s steel diameter-equivalent tape measure. Trees with multiple trunks or stems were measured at the same height and measurements for all trunks larger than four inches were collected. Damage – Identification of damage caused by pathogens or insect pests, by natural causes such as wildlife interaction, or by human activity was noted. Vigor rating – All tagged trees were evaluated based on various parameters, including amount of new growth, leaf color, bark conditions, dead wood, evidence of wilt, excessive branch or leaf necrosis, thinning of crown, presence of exudate, etc. A subjective ranking was assigned to quantify the overall physical condition of each tree based on the ratings described below: • High: A healthy and vigorously growing tree characteristic of its species and reasonably free of any visible signs of stress, disease, or pest infestation. • Moderate: A healthy and vigorous tree with minor visible signs of stress, disease, and/or pest infestation. Some dead wood, broken branches, or yellowing leaves may be present. • Low: A tree exhibiting signs of dieback, necrosis, stress, disease, or insect damage at levels above what is typically expected for the species. Symptoms could also include sparse leaf growth, predominately yellow leaves, dead or rotted wood in lower trunk, broken limbs, exposed roots, and parasite growth. • Dead: Tree had no foliage and exhibited no sign of life or vigor. 2.5 Floristic Inventory Kevin Merk and Robert Sloan conducted the 2015 botanical surveys in accordance with accepted protocols developed by the USFWS (U.S. Fish and Wildlife Service, 2000), CDFW (California Department of Fish and Wildlife, 2000), and CNPS (California Native Plant Society, 2001), which means: 1) survey personnel traversed all suitable habitat within the entire project area on foot by walking meandering transects to ensure thorough coverage of the area; 2) surveys were spaced throughout the late winter, spring, summer and fall seasons to document the site’s flora; a 3) surveys were floristic in nature, and all plant species observed were recorded and identified to a sufficient level to determine rarity. Plant taxonomy followed nomenclature included in the Jepson Manual, second addition (Baldwin et al., 2012). Robert Hoover’s The Vascular Plants of San Luis Obispo County, California (1970) was also used to identify plants observed onsite. Species not readily identifiable in the field were brought to the office for further analysis. Calflora (www.calflora .org) and the Consortium of California Herbarium were also accessed online to obtain records of special status plant observations from the region. Special status plant occurrences observed in the field were delineated using a Trimble GPS (GeoXH 6000) unit capable of sub-meter and decimeter accuracy. Subsequent surveys were conducted during the spring months of 2016 and 2017 to ground truth observations made in 2015 regarding rare plant distribution on the site. In addition, the 2016 and 2017 surveys searched for rare plants on the Basin Study Area and adjacent areas on City-owned property. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 9 2.6 Wildlife Assessment Direct observations of wildlife including their sign (i.e.: tracks and scat) were noted in the field and are included on the species list in Appendix A. The evaluation of special status animal species and identification of habitat that could support these species was based on our field observations coupled with an understanding of the species biology. Definitive or protocol-level surveys to determine the presence or absence of the animal species that may occur within the project area were not conducted. USFWS protocol surveys for special status wildlife species, such as the federal threatened California red-legged frog (Rana draytonii; CRLF), require extensive field time to be conducted only at certain times of the year. In addition, given that 2015 was the fourth year of an ongoing drought, no sufficient aquatic habitat was present to search for species such as the CRLF. Further, we relied on survey data from the immediate project vicinity contained in the CNDDB and conducted by other knowledgeable biologists to conclude whether or not certain special status animals were expected to occur onsite. Known occurrence records in the region coupled with our site-specific observations were used to make presence/absence determinations for special status wildlife potentially occurring onsite. More detailed analysis was prepared in 2017 and 2018 (Vernal Pool Habitat Assessment and Site Assessment for CRLF) and the reports are included as appendices and the findings incorporated into this revised report. 3.0 RESULTS The Froom Ranch covers approximately 109.7 acres spanning two Assessor’s parcels (APN 067- 241-030 and 067-241-031). The ranch was grazed by cattle and horses for many years, and is composed of a mix of habitat types, including annual (non-native) grassland, introduced perennial grassland (non-native), serpentine bunchgrass grassland (native), coastal scrub/chaparral, coast live oak/California bay woodland, wetland, and riparian. Also present are developed and disturbed (or ruderal) areas including existing buildings, roads, a permitted quarry in the northwestern part of the site, and a storm water detention facilit y for the neighboring Irish Hills Plaza to the north. Planted trees such as blue gum eucalyptus (Eucalyptus globulus), Monterey cypress (Hesperocyparis macrocarpa) and pepper tree (Schinus molle) are also present. The study area was enlarged since the 2015 investigation was completed to cover a proposed storm water basin (approximately 16 acres), secondary access (approximately 0.5 acre) and a potential land swap area (approximately 3.0 acres). The supplemental analysis also included the separated Calle Joaquin wetland area (approximately 1.77 acres) even though development is not proposed in this area. The revised study areas generally abut the approximately 111-acre Froom Ranch study area identified in the 2015 report and are shown on the revised Habitat Map included herein. Also included on the revised Habitat Map is an area dominated by the non-native, moderately-invasive reed fescue (Festuca arundinacea) that was not previously separated from annual grassland in the 2015 report. The occurrence is shown as Introduced Perennial Grassland and described further below. The primary parent material underlying the site is serpentinite with varying amalgamations of serpentine derived clays that affect the distribution of vegetation on the site. Serpentine rock outcrops are scattered across the upper western part of the site and support a diverse assemblage of native plants adapted to the high metal content, including some that have special regulatory status. Many of the native plants are endemic to this area, and occur nowhere else on earth. Hoover (1970) referred to this biological hot spot, which is within an approximate ten-mile radius around San Luis Obispo, as the Obispoan pocket of endemism.

In several areas, the drainages include pockets of wetland habitat. In addition, the steeper hillsides in the southwestern part of the site contain springs, or seeps, where fresh water “daylights” out of the ground. Coastal scrub/chaparral occurs on drier, shallow rocky soils on the steep slopes in the upper western part of the site. Coast live oak/California bay woodlands are present along drainage courses (identified as Drainages 1 and 2) and more north- facing slopes in the southwestern part of the site. As stated above, wetlands are present at seeps and springs formed at fractures in the serpentinite bedrock, along drainages, and along Los Osos Valley Road and Calle Joaquin where the roads have impounded surface and subsurface flow. Groundwater also influences the Calle Joaquin wetland area. Riparian habitat is also present onsite, but primarily restricted to the drainage ditch constructed along Los Osos Valley Road. A total of 204 plant species were identified in the study area, including 151 native species and 53 non-natives. Thirteen of the native plants are special status species as defined in this report. Of this number one plant is a federal and state endangered species, nine (9) are California Rare Plant Rank (CRPR) 1B species and one (1) is a CRPR 2 species. Three (3) are CRPR 4 species, which is a watch list. The endangered and CRPR 1B and 2 species meet the rarity threshold defined in Section 15380 of the California Environmental Quality Act (CEQA). CRPR 4 species typically do not meet the CEQA rarity threshold, especially when the species are widespread in the project area, and the proposed project would not jeopardize the continued existence of the species. Thirty seven (37) animal species were observed within the project area during field surveys. A soils map is provided as Figure 3 to illustrate soil map units present onsite, and Figure 4 illustrates the plant communities, or habitat types, present onsite. Figure 5 presents the results of the tree inventory, and Figures 6 and 7 illustrate occurrences of special status plants and wildlife as recorded in the CNDDB. A list of plants and animals observed during the surveys is included as Appendix A. Appendix B includes a list of all special status species and plant communities identified in the CNDDB, and identifies whether they were observed onsite. If they were not observed, an evaluation as to their potential to occur (i.e., low, moderate, or high) onsite is provided. Only those species identified with a moderate or high potential to occur onsite are considered as potentially occurring within the study area. Appendix C includes a series of photographs of representative areas of the site and special status plants taken during the field surveys. Appendix D includes the tree inventory data. Appendix E includes the Site Assessment for the California Red-Legged Frog (KMA, 2017), and Appendix F includes the Vernal Pool Habitat Assessment (KMA, 2017). Appendix G provides additional information as requested by the City’s EIR consultant. Appendix H contains the Home Depot Wetland Mitigation Plan, Year 5 Monitoring Report and Corps completion of mitigation letter. 3.1 Habitat Types Seven primary habitat types, or plant communities, were observed within the project site, and included native serpentine bunchgrass grassland (Valley and Foothill Grassland/Serpentine Bunchgrass Grassland), non-native annual grassland, introduced perennial grassland (reed fescue), coastal scrub/chaparral, coast live oak/California bay woodland, wetland, and riparian. In addition, serpentine rock outcrops are present throughout the study area that support an interesting assemblage of native plants that thrive due to the lower competition from non-native species as a result of the higher metal content. The characterizations of these plant communities generally follow those of Holland’s (1986) vegetation classification system and the plant community descriptions in the Manual of California Vegetation, second edition (Sawyer, Keeler-Wolf, and KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 13 Evens; 2009). Other mapped features onsite included drainage features that traverse the property and horticultural or ornamental plantings. The following discusses the habitat types delineated on Figure 4 and provides a characterization of the existing conditions. 3.1.1 Annual Grassland (Lolium perenne Semi-Natural Herbaceous Stands) The primary grassland type observed onsite is dominated by annual species, and occurs on the flat portions of the property historically impacted by cattle and horse grazing. The annual grassland habitat type corresponds to the perennial rye grass fields described in the Manual of California Vegetation (2009, second edition) with the exception that it is dominated by the annual Italian rye grass. It corresponds to the Non-native Grassland described by Holland (1986). The annual grassland onsite was dominated by Italian ryegrass (Lolium multiflorum = Festuca perennis). Other non-native grasses observed in this habitat type included wild oats (Avena barbata), false brome (Brachypodium distachyon), soft chess (Bromus hordeacous), and prickly sow thistle (Sonchus asper). Pockets of yellow star thistle (Centaurea solstitialis) were also present where annual grassland is adjacent to disturbed areas. This grassland type was also present along the ranch roads as they become recolonized by vegetation. Annual grasslands provide foraging, breeding habitat and movement corridors for many wildlife species. Several mammals, such as the California ground squirrel (Spermophilus beecheyi), Botta’s pocket gopher (Thomomys bottae), and deer mice (Peromyscus spp.) were observed within this habitat type. Numerous invertebrate species (such as insects), many of which provide a food source for larger animals such as lizards, birds and some small mammals can also be found within grassland communities. A variety of birds rely on open expanses of grasslands for foraging habitat. Grasslands that are bordered by habitats containing trees are particularly important for raptors because the birds can use the large trees as nesting, roosting, and as observation points to locate potential prey within nearby grassland habitats. Reptiles are also frequently found in grasslands. In addition, in areas where grasslands surround creeks, wetlands and seasonal water availability is important for wildlife. 3.1.2 Serpentine Bunchgrass Grassland Native grassland composed of purple needlegrass (Stipa pulchra) along with a mix of native and non-native species was present primarily in the upper elevation southwest portion of the study area where serpentine soils have a greater influence on plant distribution. The native grassland onsite corresponds to the Valley Needlegrass and Serpentine Bunchgrass Grasslands described by Holland (1986) and the Nassella (or Stipa) pulchra Herbaceous Alliance (purple needlegrass grassland) described by Sawyer, Keeler-Wolf and Evens (2009). Occurrences of non-native species, such as red-stemmed filaree (Erodium cicutarium), cat’s ear (Hypochaeris glabra), and hairy vetch (Vicia villosa ssp. villosa) were observed scattered in this habitat on the site, but for the most part, the area was dominated by native species such as yarrow (Achillea millefolium), Cambria morning glory (Calystegia subacaulis ssp. episcopalis), checker bloom (Sidalcea malviflora), blue-eyed grass (Sisyrinchium bellum), and western vervain (Verbena lasiostachys). Similar to the wildlife habitat discussion above, this grassland type provides suitable habitat for a number of species common to the area. 3.1.3 Introduced Perennial Grassland This grassland area is dominated by the moderately invasive reed (or tall) fescue, which is a KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 14 perennial grass used as a forage crop throughout California. It creates a dense cover on rangelands with heavy soils, such as the clay soils in the southeast part of the site. The thatch (or dead leaves) precludes native plants, and results in a monoculture of this species. Holland (1986) does not specifically describe reed fescue dominated areas and includes them into the non-native grassland category. Sawyer and Keeler-Wolf described Introduced Perennial Grassland in their first edition of the Manual of California Vegetation (1995), but it is not specifically described in the second edition. The reed fescue occurrence onsite is comparable to the Harding grass (Phalaris aquatica) swards described by Sawyer et al. (2009), since it occurs in heavier clay soils in the coastal areas of Central California. Wildlife use is expected to be similar to the other grassland types described above. 3.1.4 Coastal Scrub/Chaparral The shrubland association found on the project site was dominated by open to dense stands of California sagebrush (Artemisia californica), with other shrub constituents such as black sage (Salvia mellifera) primarily occurring on drier serpentine soils and rock outcrops in the steep upper reaches of the project site. This habitat type was described by Sawyer, Keeler-Wolf and Evens as the Artemisia californica- Salvia mellifera Shrubland Alliance (Manual of California Vegetation, 2009), and the Central Lucian Coastal Scrub by Holland (1986). In some higher elevation areas, the scrub vegetation transitioned into more chaparral habitat with species such as buck brush (Ceanothus cuneatus) forming the dominant cover. Also included in this shrub habitat were occurrences of poison oak (Toxicodendron diversilobum), bush monkey flower (Mimulus aurantiacus), California fuchsia (Epilobium canum), and deerweed (Acmispon glaber). The understory was composed of leaf litter in many places, but in some open areas the herbaceous layer consisted of scattered occurrences of non-native grasses such as ripgut brome (Bromus diandrus) and rattail fescue (Festuca myuros) with pockets of purple needlegrass also present. On the Basin and Secondary Access study areas, the coastal scrub/chaparral habitat map unit consisted mostly of early seral stage coastal scrub composed of coyote brush (Baccharis pilularis). Coastal scrub/chaparral communities provide cover and nesting habitat for a variety of animals such as western fence lizard (Sceloporus occidentalis), western rattlesnake (Crotalis viridis), blue- gray gnatcatcher (Polioptila caerulea), wrentit (Chamae fasciata), California towhee (Melazone crissalis), California mouse (Peromyscus californicus), and gray fox (Urocyon cinereoargentus). Larger mammals such as coyote (Canis latrans) and bobcat (Lynx rufus) would also be expected to occur onsite and use the entire property. Mountain lions (Felix concolor) have also been documented in the region and could occur onsite as a rare transient. 3.1.5 Coast Live Oak/California Bay Woodland The woodland community observed in the study area was dominated by coast live oak and California bay trees. This habitat type corresponds to the coast live oak woodland and California bay forest (Quercus agrifolia and Umbellularia californica woodland alliances) described by Sawyer et al. in the Manual of California Vegetation (2009). Holland (1986) classified this community as the coast live oak woodland and California bay forest. Shrubs and understory species observed in this part of the site consisted of toyon (Heteromeles arbutifolia), California coffeeberry (Rhamnus =Frangula californica), poison oak, and hummingbird sage (Salvia spathacea). In areas where California bay trees formed the dominant cover, the understory was sparse and consisted mostly of leaf litter. Similarly, very little understory vegetation was present where the oak tree canopy was dense. Oak/bay woodlands, in general, provide quality habitat for a large variety of wildlife species. Large KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 15 trees provide nesting sites and cover for birds and many mammals. Dead and decaying trees with few branches or no leaves provide “hawking sites” for raptors and perches for other bird species. They also contribute woody debris to the duff in the woodland understory, which provides foraging areas for small mammals and microclimates suitable for amphibians and reptiles in addition to fungi. Acorns are a valuable food source for many animal species, including acorn woodpecker (Melanerpes formicivorus), scrub jay (Aphelocoma corulescens), western gray squirrel (Sciurus griseus), and black-tailed deer (Odocoileus hemionus). Scrub jay, western bluebird (Sialia mexicana), turkey vulture (Cathartes aura), red-tailed hawk (Buteo jamaicensis), and black-tailed deer were observed within oak/bay woodlands onsite. Other representative animal species that could potentially occur in the oak dominated woodland on-site include western screech owl (Otus kennicottii), oak titmouse (Baeolophus inornatus), and Virginia opossum (Didelphis virginianus). 3.1.6 Wetland This habitat type is a combination of the Coastal and Valley Freshwater Marsh and Vernal Marsh vegetation communities described by Holland (1986). Sawyer, Keeler-Wolf and Evens have several classifications for wetlands that describe the perennial and seasonal wetlands onsite, including the Eleocharis macrostachya, Juncus effusus, Juncus patens, and Juncus phaeocephalus Herbaceous Alliances (spike rush, soft rush, and western marshes). In the wetland area adjacent to Calle Joaquin, a more perennial wetland was observed that supports occurrences of other wetland plants such as round-leaf leather root (Hoita orbicularis), seep spring monkey flower (Mimulus guttatus = Erythranthe guttata), silverleaf (Potentilla anserina), California bulrush (Schoenoplectus californicus), and rough sedge (Carex senta). Seasonal wetlands consisted of species such as rabbitfoot grass (Polypogon monspeliensis), Italian ryegrass, and grass poly (Lythrum hyssopifolia). Wetlands occur in nutrient-rich mineral soils that are saturated through part or all of the year. Wetland communities are best developed in locations with slow-moving, stagnant or ponded shallow water, which is the case with the impounded hydrology created by the construction of Los Osos Valley Road and Calle Joaquin and ground water influence in this area. In between the large constructed basin and the mapped wetland along Calle Joaquin, an extensive occurrence of the non- native reed fescue (Festuca arundinacea) was observed, most likely due to the historic grazing regime on the site. Small ponded areas within these wetlands provide habitat for aquatic invertebrates such as water striders (family Gerridae) and boatmen (family Carixidae), and more opportunistic amphibians such as the Pacific chorus frog (Psuedacris regilla). Seasonal ponded water is used as a drinking source for larger animals (primarily horses and cattle), and also a stop over or foraging site for ducks and great blue herons (Ardea herodias). The Calle Joaquin wetland area and constructed channel from the Irish Hills Basin leading towards Los Osos Valley Road contained numerous crayfish (Pacifastacus sp.) 3.1.7 Riparian Scrub This habitat on-site is consistent with the Arroyo Willow Shrubland Alliance as described by Sawyer, Keeler-Wolf and Evens (2009), and corresponds to the Central Coast Arroyo Willow Riparian Scrub community described by Holland (1986). This vegetation community was restricted to the lower reach of the study area along LOVR, as well as along Calle Joaquin in the enlarged study area. This habitat was mostly dominated by arroyo willow (Salix lasiolepis) and contained a few young cottonwoods in the ditch behind TJ Maxx. The dry ephemeral nature of Froom Creek and historic grazing pressure limited the extent of riparian vegetation development. In one location in KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 16 the northwestern part of the site, a small occurrence of riparian scrub was observed on the creek bank, south of the existing buildings and equipment storage yard. Common plant species observed in this habitat included Himalayan blackberry (Rubus discolor), poison oak, and stinging nettle (Urtica dioica). Central Coast Arroyo Willow Riparian Scrub is a form of forested wetland that is considered a sensitive natural community by the CDFW. Riparian communities along larger drainage courses are important for many wildlife species since the abundance of moisture and associated vegetation provide structure, materials, and food sources for nesting and roosting animals. However, the onsite riparian habitat consists of a relatively young monoculture of arroyo willows growing along a constructed roadside ditch along Los Osos Valley Road, the lower reach of Froom Creek on the Basin Study Area, and impounded along Drainage 4 by Calle Joaquin. This severely limits the forage value within the understory and expected use of this habitat as cover or as a corridor for movement along the edges of open areas. The riparian habitat in the Calle Joaquin study area extension is surrounded by urban development, which reduces the habitat value to primarily birds. In addition, people have been using the riparian habitat in this area as shelter further reducing the wildlife habitat value. Given the limited extent of this habitat onsite, common wildlife such as the Pacific chorus frog, western fence lizard, raccoon (Procyon lotor), opossum, and striped skunk (Mephitis mephitis) would be expected to use this area periodically. No large animals were observed in the onsite riparian scrub habitat during the course of field work completed on the site. In addition, the young trees are smaller in stature and limit the nesting and foraging habitat to smaller songbirds such as house wren (Troglodytes aedon), ruby-crowned kinglet (Regulus calendula), song sparrow (Melospiza melodia), black phoebe (Sayornis nigricans), and goldfinches (Carduelis spp.). As stated above, the willows create small thickets, and would not be expected to provide suitable nesting or perching habitat for larger raptors such as the red-tailed hawk that are present in the area. Seasonal water and the wetness of the soil would typically increase the value of this habitat for wildlife if it wasn’t associated with roadside ditches and isolated areas. This riparian habitat likely improves water quality by protecting the roadways from erosion, and filtering sediment and some pollutants from runoff before draining to the Calle Joaquin wetland area (i.e., the LOVR ditch), and eventually offsite towards San Luis Obispo Creek. The LOVR ditch also is periodically trimmed to keep willows from encroaching onto the road and bike lane. 3.1.8 Developed/Disturbed (Ruderal) The existing ranch roads, equipment storage area, buildings and active mine were mapped as Developed/Disturbed (also known as ruderal) habitat based on the presence of bare soils, base rock, and structures. Developed/Disturbed (Ruderal) habitat is not a native plant community, nor is it described by the vegetation classification systems used in this study since it is an anthropogenic influenced land type. Along road margins, high concentrations of invasive, non-native species were present, likely due to the historic disturbance. Some plants characteristic of the onsite annual grassland habitat described above were present, in addition to dominant weedy species such as Italian thistle (Carduus pycnocephalus) and yellow star thistle. Because of the highly disturbed nature of this habitat, it is of marginal value to wildlife. Nonetheless, its proximity to the natural plant communities onsite allow several common species such as the western fence lizard and California ground squirrel to utilize disturbed or ruderal areas of the site for basking in the sun and foraging. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 17 3.1.9 Serpentine Rock Outcrop Scattered throughout the steeper portions of site, primarily in the southwest part of the study area, are areas of serpentine rock outcroppings. The exposed serpentine rocks were mostly bare, but did support native plants in cracks or areas of talus accumulation. Plants observed included several species of mariposa lily (Calochortus clavatus ssp. clavatus and C. obispoensis), cryptantha (Cryptantha clevelandii), mouse gray dudleya (Dudleya abramsii ssp. murina), Blochman’s dudleya (Dudleya blochmaniae), and stinging phacelia (Phacelia imbricata). 3.1.10 Ornamental Trees including Eucalyptus, Cypress and Sycamore Trees Within the study area, planted blue gum eucalyptus, Monterey cypress and pepper trees were present. In addition, three sycamore (Platanus racemosa) trees were observed in the permitted quarry in the northwestern part of the site. The extent of tree canopies was delineated on the habitat map included as Figure 4. While bird nests were not observed during surveys, the larger eucalyptus trees provide perching and nesting opportunities for a variety of birds, including raptors such as great horned owl and red-tailed hawk. 3.2 Tree Survey A total of 96 trees with DBH of four (4) inches or greater were tagged within the study area, and included five (5) species of native trees and two (2) non-native tree species. Please refer to Figure 5 – the Tree Survey Map. Trees were concentrated primarily along Drainage 1. Native trees recorded included 41 Coast live oak (Quercus agrifolia), 31 California bay (Umbellularia californica), three (3) western sycamore (Platanus racemosa), three (3) Fremont cottonwood (Populus fremontii), three (3) arroyo willow (Salix lasiolepis), and one (1) holly-leaf cherry (Prunus ilicifolia). Non-native trees present included 12 blue gum eucalyptus (Eucalyptus globulus), and two (2) Peruvian pepper (Schinus molle). Generally, the majority of trees present exhibited high or moderate vigor. Several large oak and bay trees exhibited hollow or dead main trunks, but had large, healthy secondary trunk growth. Several trees exhibited sparse canopy growth and poor leaf development. The very steep upper portion of Drainage 1 in the southwestern corner of the site contained oak and bay trees in a narrow canyon area. This area was not accessible due to steep terrain, dense vegetation and poison oak. The LOVR roadside channel contained approximately 200 arroyo willow shrubs/trees that have established along the channel over the last 10 years. These willows consisted primarily of multi- stemmed specimens (some with 10 or more trunks) located mostly within the centerline of the ditch. The willow occurrences were mapped as riparian habitat as part of the plant community or habitat type mapping effort, and the areal extent calculated. The Basin Study Area on the Mountainbrook Church property also contained trees that were not included in the tree inventory. Young arroyo willows were present along the lower portion of Froom Creek and along Drainage 4, most of which were less than four inches DBH. A cluster of blue gum eucalyptus trees were also present near Froom Creek by Calle Joaquin, and two small Monterey cypress trees were observed on the hillside below the church.

The creek channel bisects the study area in a generally north to south direction, and ultimately passes beneath Calle Joaquin and U.S. Highway 101 via two concrete box culverts (approximate location shown on Figure 4), heading to its confluence with San Luis Obispo Creek. San Luis Obispo Creek flows in a westerly direction ultimately connecting to the Pacific Ocean at Avila Beach. Due to the lack of dominant wetland vegetation within or adjacent to the channel and cobble/gravel bed, Froom Creek was classified as Riverine Intermittent Streambed per Cowardin, and as non-wetland waters of the U.S. and state of California subject to USACE, RWQCB and CDFW jurisdiction. Three small ephemeral drainage features (identified as Drainages 1, 2, and 3) are present in the southwestern portion of the Froom Ranch study area that are tributaries to Froom Creek. Due to the presence of a defined bed and bank, OHWM, and hydrologic connectivity to Froom Creek, these small features were classified as Riverine Intermittent Streambed per Cowardin, and constitute jurisdictional non-wetland waters of the U.S. and state of California. While these drainages were mostly comprised of upland vegetation, areas of wetland habitat were observed and mapped in specific locations. In addition, several seeps or springs were observed originating on adjacent hillsides and were hydrologically connected to the drainage feature. In-channel areas and abutting areas dominated by wetland vegetation are classified as Palustrine Emergent Wetland per Cowardin, and constitute wetlands under USACE, RWQCB and CDFW jurisdiction. The enlarged study area expanded onto the Mountainbrook Church property to cover the storm water basin, encompasses a fourth drainage feature (identified as Drainage 4 on the Habitat Map). This feature originates on the hillside just to the south of the Drainage 1 watershed, west of the church. It flows in a general west to east direction and leaves the study area through a culvert under Calle Joaquin. It does not appear to be connected to Froom Creek. Surface flow when present is apparently directed further south into a ditch along Highway 101. Some wetland habitat was observed in the channel of the drainage feature (under the arroyo willow riparian scrub) near the box culvert under Calle Joaquin. Further upstream outside the study area, the channel of Drainage 4 was dominated with annual grasses and coyote brush. 3.3.2 LOVR Roadside Channel The LOVR Roadside Channel (or ditch) is located along the northern property boundary, and contained a dense willow canopy and wetland understory, along a narrow and shallow constructed channel area. The willow canopy has developed since the ditch was constructed, and the channel appears to have lost capacity due to vegetative growth and sediment accumulation. Current channel dimensions in this area ranged from six inches to two feet deep, and one to four feet wide. Willow canopy and wetland vegetation extended beyond the channel banks into the adjacent meadow area, apparently the result of the constructed roadways impounding seasonal surface and subsurface water. Because the majority of in-channel and abutting areas were dominated by wetland vegetation, the LOVR Roadside Channel is classified as Palustrine Emergent Wetland per Cowardin, and constitutes wetland waters under USACE, RWQCB and CDFW jurisdiction. Jurisdictional boundaries in this area were mapped into the LOVR right-of way to the road shoulder, which was outside the Froom Ranch property line. Please refer to the KMA Delineation of Waters of The U.S. and State of California for further detail. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 20 3.3.3 Detention Basins The northern basin was an approximately one-acre temporary settling basin const ructed in upland grassland areas to receive storm water runoff during the construction of Home Depot. During construction, a swale and culverts were installed behind the current Whole Foods and TJ Maxx buildings to direct surface runoff into this basin and let it settle before spreading overland via notches cut in the earthen berm to support the historic wetland feature along LOVR. Seasonally ponded water was evident in the northern basin during aerial photograph review, and patchy occurrences of seasonal wetland vegetation were noted in the bottom of the basin (approximately 0.7 acre) during field work conducted in 2015 confirming some wetland habitat attributes were still present even though storm water from the developed areas was no longer directed into this basin. It is our understanding that once the Irish Hills Plaza basin was constructed, stormwater runoff from neighboring development was no longer directed into the temporary settling basin. The temporary basin was not identified as a potential jurisdictional feature subject to Clean Water Act regulation since it was constructed in an upland as a temporary settling basin to support construction of the neighboring project. The Corps concurred in their Preliminary Jurisdictional Determination (2016 letter from the Corps to John Madonna) since artificial lakes or ponds created by excavating and/or diking dry land and used exclusively for such purposes as stock watering, irrigation, settling basins or rice growing are not regulated under the Clean Water Act pursuant to the Clean Water Rule of 2015. As such, the applicant removed it in 2017 and the temporary basin is no longer present. The area now consists of plants characteristic of the surrounding ruderal and annual grassland habitats. Please refer to Appendix G for additional discussion of the basins. The approximately 3.2-acre southern basin complex, known as the Irish Hills Plaza basin, is a stormwater management feature constructed in upland grassland habitat that receives runoff from the neighboring project. Storm water is directed into this basin by a 48-inch pipe. The basin complex consists of a smaller forebay or northern basin, larger main basin, and a spillway. It was sized to contain runoff from any future Phase II development within the Froom Ranch study area (Wallace Group, 2006). This basin has an extensive French drain system around the perimeter to not inhibit groundwater movement and surface flow toward the Calle Joaquin wetland area. The western perimeter French drain and forebay release water to the LOVR Roadside Channel by a storm drain outfall and swale, which then flows to the Calle Joaquin wetland. During large storm events, the basin can overtop and discharge water into the wet meadow area along Calle Joaquin via a concrete spillway. Otherwise, storm water piped into the basin from developed areas to the north leaves through evaporation and percolation into the ground. This feature was also not identified as a potential Clean Water Act jurisdictional feature based on similar rationale described above as it was constructed in an upland area and is part of the neighboring project’s storm water drainage system. During the 2015 surveys, the Irish Hills Plaza basin was dry and contained mostly grasses and weeds characteristic of the surrounding annual grassland habitat. Aerial photograph review showed the basin had been graded and cleared of vegetation as recently as 2013. The slopes were relatively unaffected, and creeping wild rye (Leymus or Elymus triticoides), likely applied in the hydroseed mix following construction, was still present in several areas. During the 2016/2017 rain season, standing water was present in the forebay and wetland vegetation was observed in an approximate 0.6 acre area. The main basin also had seasonally moist soils and patchy wetland vegetation was mixed with upland species in an estimated 1.4 acre area. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 21 Because both basins including the swale/ditch behind Whole Foods are man-made structures constructed in uplands that are fed primarily by piping concentrated hardscape storm water runoff from neighboring development, they were determined to not be subject to Clean Water Act or California Fish and Game Code requirements. In 2015, the Corps (or USACE) reviewed the project Wetland Delineation Report, which identified these features as “spigot wetlands” and confirmed the extent of their Clean Water Act jurisdiction did not include the basins as Waters of the U.S. A spigot wetland would not persist if the faucet (in this case, the pipe delivering storm water runoff) was turned off. Please refer to the letter from Erin Hanlon, USACE Regulatory Project Manager, to Mr. John Madonna dated September 24, 2015 included in the Wetland Delineation Report (KMA, 2015) and Appendix G for further discussion. 3.4 Soils The NRCS identified eight soil map units as occurring on the Froom Ranch study area (refer to Figure 3). Enlarging the study area to cover the proposed storm water basin identified an additional soil map unit for a total of nine within the study areas shown on the Soils Map. Of these map units, Corducci-Typic Xerofluvents (previously mapped as Riverwash) and Xererts-Xerolls are listed as hydric soils by the NRCS California Hydric Soils List for San Luis Obispo County. An unnamed component of Cropley clay, 0-2 % slopes, and Salinas silty clay loam, 0-2% slopes, are also considered hydric when present in drainageways or depressions. Cibo clay consists of a 0 to 31 inch, dark brown (7.5YR 3/2) clay formed in residual material weathered from hard metasedimentary rocks, and commonly displaying fine roots. The structure is coarse and angular blocky. This moderately to steeply sloping soil is considered very poorly drained. The soil has moderate erodibility and high shrink-swell characteristics, and potential septic system constraints due to steep slopes, shallow depth to bedrock, and slow percolation. Cropley clay 0-2 % slopes. Cropley clay consists of a dark gray or black (10YR 4/1, 3/1, 2/1 moist) clay horizon about 36 inches thick, underlain by a light brown calcareous clay loam to 60 inches or more. Permeability of this soil is slow and the available water capacity is high. Cropley soils formed in alluvium developed from sedimentary rocks. An unnamed component of Cropley clay is listed as a hydric soil when present in drainageways. This inclusion is typically very dark gray throughout, with mottles present in the lower horizons. This dark gray soil was not observed on- site. Mapped inclusions within this series include Diablo clay, Los Osos loam, and Salinas silty clay loam. Diablo and Cibo clays 9-15 and 15 - 30 % slopes. Diablo clay consists of a 0 to 23 inch, black (10YR 2/1) clay formed in residual material weathered from sandstone, shale, or mudstone, commonly displaying fine roots to four inches. The structure is granular to 4 inches, and coarse, angular, and blocky to 23 inches. This moderately to steeply sloping soil is very poorly drained. The soil has moderate erodibility and high shrink-swell characteristics, and has potential septic system constraints due to steep slopes and slow percolation. Los Osos-Diablo Complex 5-9 and 15-30% slopes. Los Osos-Diablo Complex consists of about 40 percent Los Osos soil, and 35 percent Diablo soil, found on foothills and mountain ridge tops. These soils are moderately deep, well drained, and have low permeability. Typical Los Osos-Diablo Complex soil (moist) consists of a very dark grayish brown (10YR 3/2) loam or black (10YR 2/2) clay, 40-60 inches thick. Permeability of Los Osos-Diablo Complex soil is rapid, and the available water capacity is low. The available water capacity of Los Osos-Diablo Complex soil is low to very high, while surface runoff is rapid. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 22 Obispo-Rock outcrop 15-75% slopes. Obispo-Rock outcrop consists of about 50 percent Obispo soil and 30 percent Rock outcrop. Obispo soils are shallow, well drained, slowly permeable soils formed in residual materials weathered from serpentine rock. Typical Obispo soil (moist) consists of a black (10YR 2/1) clay to a depth of about 18 inches, underlain by serpentine rock. The available water capacity of Obispo-Rock outcrop soil is low, while surface runoff is rapid or very rapid. Riverwash/Corducci-Typic Xerofluvents, 0-5% slopes occasionally flooded includes soils found in active stream and river channels, and consists of excessively drained, water deposited sand, loamy sand, and sandy loam with varying amounts of gravel and cobbles present. Riverwash soils located in and along stream channels are generally subject to flooding during and immediately after every storm. Riverwash soils are typically excessively drained, but can be somewhat poorly drained in low lying areas. Permeability is very rapid, surface runoff is very slow, and the erosion hazard is variable. Typical inclusions include Psamments and Fluvents, and Corralitos soils. Riverwash and Psamments and Fluvents located in drainageways are listed as hydric soils. These soils have a Hydric Criteria Code of 4: soils that are frequently flooded for long or very long duration during the growing season. Salinas silty clay loam, 0-2% slopes. This is a very deep, well drained, nearly level soil on alluvial fans and plains. It formed in alluvium weathered from sedimentary rocks. Typically, the surface layer is dark gray silty clay loam underlain by stratified layers of very fine sandy loam and silty clay loam. Permeability is moderately slow, and the available water capacity is high or very high. Surface runoff is slow, and the hazard of water erosion is slight. This soil can be considered hydric when associated with depressions. Xererts-Xerolls-Urban land complex 0-15% slopes. The Xererts-Xerolls-Urban land complex consists of nearly level to strongly sloping soils and miscellaneous areas that are covered by urban structures. Most areas of these soils are used for urban development. The soil materials have been modified by earthmoving equipment or covered by urban structures so that much of their original shape and physical characteristics have been altered. The Xererts of this complex are Cropley or Los Osos-Diablo soils. The percentage of the various soils in this complex and the degree of urbanization vary from place to place (SCS 1984). An unnamed inclusion of the Xererts-Xerolls- Urban land complex associated with depressions has a Hydric Criteria Code of 2A: soils in Aquic suborder that are somewhat poorly drained and have a frequently occurring water table less than 0.5 feet from the surface for a significant period (usually 14 consecutive days or more) during the growing season. 3.5 Special Status Biological Resources The San Luis Obispo area supports numerous special status, or rare, plant communities, and species of plants and animals. As stated in the methodology section above, the biological resources inventory used a six quadrangle search of the CNDDB in addition to the review of environmental documents prepared for projects in the area to identify special status resources that could be present onsite. Appendix B provides a table with the special status biological resources occurrence data, listing status for all special status species and habitats, the results of the surveys, and an evaluation of wildlife presence or potential to occur onsite. The following discussion provides further detail regarding the special status biological resources occurring or potentially occurring on the Froom Ranch study area. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 23 3.5.1 Special Status Natural Communities The CNDDB search identified occurrences of nine (9) special status plant communities within the greater area and included Central Dune Scrub, Central Foredunes, Central Maritime Chaparral, Coastal Brackish Marsh, Coastal and Valley Freshwater Marsh, Northern Coastal Marsh, Northern Interior Cypress Forest, Serpentine Bunchgrass, and Valley and Foothill Grassland. Please refer to Figure 6 illustrating the botanical data obtained from the CNDDB. Our observations onsite identified another special status natural community in the area, consisting of the riparian habitat along the LOVR ditch, lower reach of Drainage 4 and Froom Creek. Three special status natural communities, including the Coastal and Valley Freshwater Marsh (Wetland), Riparian (Riparian Scrub), and the Serpentine Bunchgrass Grassland were observed onsite (please refer to Figure 4, the Habitat Map) and meet the special status natural communities definition pursuant to the CDFW. In addition, special status plant occurrences were observed on serpentine rock outcrops and in areas of annual grassland. Therefore, where rare plant occurrences are present, the supporting habitat should also be considered special status natural communities. 3.4.2 Special Status Plants The CNDDB contains records of many special status plant species that are known to occur within the greater San Luis Obispo area, including past observations from the study area (please refer to Figure 6). Special status plant species typically have highly localized habitat requirements and many are known to occur on serpentine rock outcrops and soils, active and stabilized coastal dunes, or in maritime chaparral, and brackish marsh habitats. Coastal dunes, central maritime chaparral and brackish marsh habitats do not occur on the property, and therefore, species such as beach spectacle pod (Dithyrea maritima), Morro manzanita (Arctostaphylos morroensis), and salt marsh bird’s beak (Chloropyron maritimum) are not expected to occur onsite based on the lack of suitable habitat. In addition, a number of species identified in the database search occur at higher elevations in the Santa Lucia Mountains further to the north of the study area, and are not expected to occur onsite based on range restrictions. This includes species such as the San Benito fritillary (Fritillaria viridea), hooked popcorn flower (Plagiobothrys uncinatus), and Cuesta Pass checkerbloom (Sidalcea hickmanii ssp. anomala). While elevation alone is not sufficient to rule out a species from a particular study area, these species were not observed during the focused surveys of the property at a time of year when they would have been identifiable. Therefore, it is reasonable to conclude that they are not expected to occur onsite. Moreover, special status perennial shrubs would have been identifiable at the time the field surveys were conducted. Perennial shrubs such as Arroyo de la Cruz manzanita (Arctostaphylos cruzensis), Santa Lucia manzanita (Arctostaphylos luciana), and Santa Margarita manzanita (Arctostaphylos pilosula) were not observed during field surveys, and as a result, are not expected to occur in the study area.

Surveys conducted in 2015 located the 13 special status plants listed below. Please refer to Figure 7 for species locations. • Blochman's dudleya (Dudleya blochmaniae; CRPR List 1B.1); • Brewer's spineflower (Chorizanthe breweri; CRPR List 1B.3); • Cambria morning glory (Calystegia subacaulis ssp. episcopalis; CRPR List 4.2); • Chaparral ragwort (Senecio aphanactis; CRPR List 2.2); • Chorro Creek bog thistle (Cirsium fontinale var. obispoense; federal and state endangered and CRPR List 1B.2); • club hair mariposa lily (Calochortus clavatus ssp. clavatus CRPR List 4.3); • Congdon's tarplant (Centromadia parryi ssp. congdonii; CRPR List 1B.1); • Eastwood’s larkspur (Delphinium parryi ssp. eastwoodiae; CRPR List 1B.2); • Jones's layia (Layia jonesii; CRPR List 1B.2); • mouse-gray dudleya (Dudleya abramsii ssp. murina; CRPR List 1B.2); • Palmer’s spineflower (Chorizanthe palmeri: CRPR List 4.2); • San Luis mariposa lily (Calochortus obispoensis; CRPR List 1B.2); and • San Luis Obispo owl's-clover (Castilleja densiflora ssp. obispoensis; CRPR List 1B.2). Even though drought conditions were experienced in the project region over the course of the last four years, sufficient rain fell during the 2015 growing season to allow an accurate inventory of the site’s vegetation and identification of special status plants on the study area as shown on Figure 7 – the Special Status Plant Occurrences Map. Subsequent field surveys conducted in the spring and summer of 2016 and 2017 confirmed special status plants observed onsite were in the same general locations observed in 2015. As stated above, CRPR 4 plants observed onsite are on a watch list and are common throughout the San Luis Obispo area. The three CRPR 4 species were observed in the southwestern part of the site on grassland and serpentine rock outcroppings. They are components of much larger populations in the surrounding Irish Hills, and any future development would not jeopardize the continued existence of the watch list species observed onsite. Therefore, CRPR 4 species are not expected to meet the rarity threshold defined under Section 15380 of CEQA. 3.4.3 Special Status Animals The CNDDB contained occurrence data for numerous special status animal species in the general area. Please refer to Figure 8 and Appendix B for the special status animals that were evaluated in this study, and a determination as to their potential to occur onsite. Similar to the plant evaluation above, many of these special status animals are not expected to occur on the subject site due to the lack of suitable habitat and range restrictions. Species such as California black rail (Rallus longirostris obsoletus), western snowy plover (Charadrius alexandrines nivosus), Morro shoulderband snail (Helminthoglypta walkeriana), and Morro Bay blue butterfly (Plebejus icarioides morroensis) are coastal species that have specific habitat attributes (i.e., coastal dune scrub, dune sands, active dunes) and requirements that are not present onsite, and therefore, are not expected to occur on the property because suitable habitat is not present.

Given the large expanses of open grasslands and mixed shrub/woodlands on the property, many of the special status birds known from the general area could potentially occur on the property at least as transients moving through the region seasonally. Ground nesting birds, and small songbirds could potentially use the site for nesting activities. Special status species identified in the CNDDB and that could potentially occur onsite include the Cooper’s hawk (Accipiter cooperii) and white-tailed kite (Elanus leucurus). Bat species, such as the pallid bat (Antrozous pallidus), Townsend’s big-eared bat (Corynorhinus townsendii), and various species of Myotis have large home ranges, and could forage over and around the site, as well as roost in trees and under the eves of existing structures. The Monarch butterfly (Danaus plexippus) is a relatively common species from the general area, and could forage onsite. It would not be expected to overwinter on the study area because the species requires specific autumnal and overwintering habitat attributes typically found closer to the coast . The small groupings of eucalyptus trees, and riparian oak and bay trees that are present in the study area are not suitable to support monarch butterfly overwintering habitat. Based on the lack of sandy soils, the legless lizard (Anniella pulchra) and coast horned lizard (Phrynosoma blainvillii) are not expected to occur in the coastal scrub/chaparral habitats mapped onsite. The heavy clay soils on the property preclude fossorial (burrowing) reptiles such as the legless lizard from occurring under shrubs on the slopes or flatter areas of the site. Species such as the San Diego woodrat (Neotoma lepida intermedia) and American badger (Taxidea taxus) could potentially occur onsite, and woodrat nests were observed in dense oak/California bay woodland areas in the southwestern part of the property. The portion of Froom Creek within the site does not appear to contain appropriate aquatic and riparian habitat to support the federally threatened California red-legged frog (Rana draytonii; CRLF). Please refer to the Site Assessment for the California Red-Legged Frog (KMA, 2017) included as an appendix of this report for further detail. The closest known occurrence is from the waste water treatment ponds on the east side of Highway 101. No records of CRLF in the immediate project area were found during the 2015 analysis. Surveys on City-owned property further west-northwest of the study area identified CRLF in areas of aquatic habitat in upper Froom Creek. The portion of Froom Creek in the study area does not contain suitable hydroperiod (i.e., flowing water or pools two feet deep or greater during the late spring or summer months) to support a breeding population of CRLF. The small tributary drainages in the higher elevations of the study area also did not contain suitable aquatic habitat to support CRLF, and observed in-channel pools in Drainage 1 were too shallow (most less than 16 inches deep) and did not persist for a long enough time to support CRLF breeding. In 2015, the constructed detention basins onsite lacked suitable aquatic habitat with a sufficient hydroperiod to support CRLF breeding, and did not contain any emergent vegetation. The basins were also cleared and vegetation was removed in 2013. However, in 2017, the forebay of the Irish Hills Plaza basin contained standing water and wetland vegetation into September, but water depths were less than 12 inches, which is typically not suitable for CRLF. The Calle Joaquin wetland onsite contained a small area of standing water and emergent wetland vegetation was also present. However, the aquatic habitat supported large numbers of crayfish, a known predator of CRLF, which also likely precludes CRLF from persisting in this area. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 29 Three additional day surveys and five night surveys for CRLF were conducted in the Froom Ranch study area in the spring, summer and fall of 2018 following USFWS guidelines (2005) as part of the biological resources update. The surveys focused on the seasonally ponded areas in Drainage 1, Froom Creek and along Calle Joaquin identified in the 2017 Site Assessment report. Surveys also included seasonally ponded areas observed in the separated Calle Joaquin wetland (south side of the road) next to the hotel. The Irish Hills Plaza basin forebay was also searched during the surveys when surface water was present even though it was less than eight-inches deep. No CRLF were observed during the surveys. Methods and results of the surveys will be presented in a separate, stand-alone report currently in preparation. Southern steelhead (Oncorhynchus mykiss irideus) are known to occur further to the southeast of the project site in San Luis Obispo Creek. They have also been identified as occurring within the upper reaches of Froom Creek outside the study area (personal communication with Freddy Otte, City of San Luis Obispo Biologist). Also, other highly aquatic species such as the western pond turtle (Emys marmorata), the two-striped garter snake (Thamnophis hammondii), and the Coast Range newt (Taricha torosa torosa) are not expected to occur onsite in Froom Creek, its tributaries or the constructed basins based on the lack of prolonged seasonal in-channel pools lasting at least 10 weeks and regular flowing water. The USFWS has identified critical habitat for steelhead and CRLF in the region. The project site, however, does not occur in the critical habitat polygons developed for CRLF, but Froom Creek is identified as critical habitat for southern steelhead. It is unlikely, however, that Froom Creek supports a steelhead run since it is separated from San Luis Obispo Creek by a box culvert that is over 300 feet long running under Calle Joaquin and Highway 101. The Coast Range newt is a species of concern known to occur in the Santa Lucia Mountains and Santa Margarita region north of the project site. This species lives in terrestrial habitats and breeds in ponds and slow moving streams during winter months. Although the species is not documented from the Irish Hills of the San Luis Range, there is potential for this animal to occur further upstream in the watershed. It is unlikely to occur within the study area due to the lack of suitable habitat consisting of prolonged pools that form on a more regular basis than what has been observed on the study area. The evaluation of special status species occurrences onsite was based on a habitat suitability analysis coupled with on the ground observations. Please refer to Appendix B for further detail. As stated above, protocol-level surveys to determine the presence or absence of CRLF were conducted in 2018, and also included direct observation of onsite and offsite conditions, inspection of the drainage channels and their respective hydrologic regime, and review of biological reports and the CNDDB records documenting recorded occurrence data from the area to conclude whether or not a particular species could be expected to occur. The Vernal Pool Habitat Assessment and Site Assessment for CRLF were prepared in 2017, and provide further information related to aquatic habitats and the potential for special status wildlife occurrence onsite. The following information clarifies whether potential habitat for a species is present, if the species was observed during field work, and provides the likelihood (i.e., low, moderate or high) of actual encounter of the particular species onsite. The purpose of this analysis is to rule out those species that have a low likelihood or potential to occur onsite and help the EIR consultant focus the list of potential mitigation measures to cover only those species with a moderate or high likelihood of occurring within the project boundaries that could be affected by the proposed project. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 30 The 2015 analysis reviewed numerous special status wildlife and identified species that have the potential to occur at least on a seasonal basis within the project boundaries based on the presence of suitable habitat. The terminology used in the 2015 BRI analysis was: 1. “Could Occur” (i.e., potential habitat was present but species was not observed) 2. “Unlikely to Occur” (i.e., site may be within the range of the species but suitable habitat was lacking or sub-optimal); or 3. “Not Expected to Occur” (i.e., no suitable habitat was present, the species is not known from the project vicinity, and/or the species range does not include the project site). The potential to occur determination was based on the presence of suitable habitat within the project boundaries, and the site is within the known range of a particular species. Twenty-two special status animals were identified in the 2015 BRI as having potential to occur onsite. The supplemental analysis conducted in 2018 further refined this list by identifying the varying levels of likelihood of occurrence (i.e., low, moderate, or high). This was completed to help the EIR consultant prescribe appropriate mitigation in the impact analysis for those species with a moderate or high likelihood of occurring onsite: • American badger (Taxidea taxus; species of special concern) is a highly mobile species known to occur in native habitats surrounding the San Luis Obispo area. Badgers and badger road kill have been observed along Los Osos Valley Road and Highway 1 west of San Luis Obispo (Merk personal observation), and recorded occurrences from the Camp San Luis Obispo area are documented in the California Natural Diversity Data Base (CDNNB) maintained by the California Department of Fish and Wildlife (CDFW). While no sign or burrows were observed on the project site, badgers living in the Irish Hills could move onto or through the property during foraging activities. No large ground squirrel colonies were observed onsite, so prey base and denning opportunities are not optimal, but there is moderate likelihood that the species could move through all habitat types onsite and potentially den in open areas within grassland, coastal scrub/chaparral, and coast live oak/CA bay woodland habitats onsite. • Burrowing owl (Athene cunicularia; species of special concern) is a wide-ranging species known to occur more commonly in the interior habitats of San Luis Obispo County. This species has been observed in the San Luis Obispo area, primarily during winter movement periods. Most recently the species was documented on the Chevron Tank Farm property to the east of the project site (Padre Associates, 2008). The species has not been recorded breeding in the immediate vicinity, and past work by Comrack and Mayer (2003) concluded that burrowing owls may no longer breed in the coastal part of San Luis Obispo County. Breeding is primarily in the inland areas such as on the Carrizo Plain. Still, suitable grassland and open coastal scrub habitats are present onsite that could be used by burrowing owls during winter migration periods when individuals are in the area. No large ground squirrel colonies were observed onsite that would provide a substantial prey base or nesting opportunities for this species. It appears unlikely that this species would nest onsite, and therefore, a low likelihood exists for burrowing owl to occur onsite. • California horned lark (Eremophila alpestris actia; CDFW watch list). Grazed grasslands onsite could support this ground nesting species since it is known to forage and breed in open, flat habitats with short vegetation in the Central Coast region. Although not observed onsite during field surveys, this is a wide-ranging bird known to occur in the greater San Luis Obispo area. Given the presence of suitable habitat and known records of the species in San Luis Obispo County, a moderate likelihood exists for this species to occur onsite. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 31 • Cooper’s hawk (Accipiter cooperi; watch list) is known to occur throughout coastal San Luis Obispo County, and an individual was observed in the coast live oak/CA bay woodland habitat along Drainage 1 in the southern part of the property during field work conducted in 2015. While no direct observation of a Cooper’s hawk nest site was made, this species would be expected to forage throughout the site, and potentially nest within the coast live oak/CA bay and eucalyptus woodlands present in the southern part of the property. The riparian scrub habitat along Los Osos Valley Road appears to provide marginal habitat for this species due to its thicket forming nature, which does not provide easy access for Cooper’s hawk foraging or suitable nest building sites. This species was observed onsite and there is a high likelihood of encountering the species in woodland habitats within the project site. • Golden eagle (Aquila chrysaetos; watch list and CDFW Fully Protected) is known to occur in the expansive open spaces surrounding San Luis Obispo and has a large home range. Golden eagle would be expected as a rare to uncommon visitor to the Froom Ranch. The grassland habitat could potentially support foraging habitat for this species, but large ground squirrel colonies or other substantial prey base was not observed onsite. While the coast live oak/CA bay woodlands could potentially support nesting habitat for the species, no large stick nests indicative of golden eagles were observed during the field work for this project, and no recorded occurrences of this species are present in close proximity to the site. The active hiking and biking trails and regular human activity around the site likely deter the golden eagle from nesting onsite and in the immediate area. Therefore, there is a low likelihood that the golden eagle would occur onsite beyond just a rare or uncommon fly over. • Loggerhead shrike (Lanius ludovicianus; species of special concern) is a resident in arid regions of San Luis Obispo County, primarily north and east of the Santa Lucia Mountains. No shrikes were observed during field work, but coastal scrub/chaparral habitat is present onsite that could support this species. Therefore, a moderate likelihood exists for this species to occur onsite and nest in the coastal scrub/chaparral and forage in the grasslands, scrub and edges of coast live oak/CA bay woodland habitats. • Merlin (Falco columbarius; watch list) is known to winter in San Luis Obispo County, but is not expected to breed in the project area. Most merlin observations have been made north of the Cuesta Grade where this species would be expected to nest. Still, this highly mobile raptor could potentially fly over the site and forage in the grasslands when moving through the area. It is not expected to nest on the project site, and as such, has a low likelihood of being encountered on the site. • Northern harrier (Circus cyaneus; species of special concern) is known to occur throughout the grassland and scrub habitats surrounding San Luis Obispo. It was observed on several occasions foraging over the grasslands onsite. It is a ground nesting bird, and no nest site indicative of northern harrier was observed during the field work. Given the lack of tall grasses away from regular human activities, it appears to have a low likelihood of nesting onsite. The northern harrier could forage onsite, but has a low likelihood of nesting given regular grazing, hiking/biking trails and other regular human activities in close proximity to the grasslands onsite. • Purple martin (Progne subis; species of special concern) typically nests in sycamore trees (Platanus racemosa) along riparian corridors. The species was not observed during field work, and the few sycamore trees observed onsite are within the active mine area KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 32 mapped as developed/disturbed (refer to habitat map included as Figure 4 in the BRI). There is a low likelihood that the purple martin would forage or nest onsite given the lack of well-developed riparian trees along onsite drainages. • Sharp-shinned hawk (Accipiter striatus; watch list) is a small migratory raptor that feeds on birds and small mammals. It is known to occur throughout the United States and Canada and can be observed in coastal San Luis Obispo County in a variety of woodland habitats, typically near water, during fall migration. Sharp-shinned hawks usually migrate to the northern United States and Canada for breeding, but some individuals may remain in the region year-round. The coast live oak/CA bay woodland habitat was identified as potentially suitable habitat for the species, but no large stick nests other than one occupied by a red-tailed hawk (Buteo jamaicensis) in a large eucalyptus tree were observed. Sharp- shinned hawk could forage onsite during the fall and winter, and has a low likelihood of nesting onsite in the spring and summer. • Tricolored blackbird (Agelaius tricolor; candidate species and species of special concern) is a colonial species that nests in emergent vegetation in freshwater habitats. It forages over a wide area, typically in grassland and wetland habitats near the nesting colony. The tule patch in the Calle Joaquin wetland area was deemed to not be large enough to support nesting activities at the time the BRI study was completed. While the tule patch has enlarged over time, which increases its potential for use by tricolored blackbirds, it is close to the roadway and regular human activities, which discourages nesting. The onsite grasslands near the tule patch are suitable foraging habitat. This species has a moderate likelihood of nesting in the Calle Joaquin wetland area and foraging in the grassland habitat in the southeast part of the site. • White-tailed kite (Elanus leucurus; CDFW Fully Protected) has been observed foraging over grassland and wetland habitats in the Los Osos Valley primarily west of San Luis Obispo (Merk personal observation). It is known to nest in Monterey cypress, coast live oak and other large riparian trees. Suitable foraging habitat is present in the grasslands on the project site, but no kites were observed onsite during field work. Suitable nesting habitat is present in the coast live oak/CA bay woodland. There is a moderate likelihood that the white-tailed kite could occur onsite during foraging and nesting activities. • Yellow warbler (Dendroica petechia brewsteri; species of special concern) is a small songbird that occurs in riparian habitats, nesting in willows and cottonwoods. It was not observed onsite during field work conducted for the BRI or subsequent studies. Although no recording nesting observations for this species in the San Luis Obispo area were identified, suitable foraging habitat is present in the riparian scrub habitat along Los Osos Valley Road. This species could potentially forage onsite, but has a low likelihood that it would nest on the property. • Big free-tailed bat (Nyctinomops macrotis; species of special concern) is known to occur in low-lying, arid areas of Southern California typically roosting on high cliffs or rocky outcroppings. The site does support some rocky serpentine outcroppings in the southern part of the property, but large high cliffs are absent. Further outside the study area on the upper ridgelines in the Irish Hills, potentially suitable roosting habitat may be present. This species could potentially forage onsite, but low likelihood that it would roost within the project boundaries. • Hoary bat (Lasiurus cinereus; special animal) typically roosts in dense foliage of large trees near open water. The BRI concluded suitable foraging habitat was present on the site KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 33 given the mosaic of habitat types present. It was also determined that the hoary bat could roost in the coast live oak/CA bay woodland habitat in the southern part of the property along Drainages 1 and 2. This species has a moderate likelihood of occurring onsite. • Pallid bat (Antrozous pallidus; species of special concern) is a wide-ranging species that occurs in a variety of habitats. It can be expected to occur onsite foraging over grassland, coastal scrub/chaparral, and woodland habitats. It is also possible that this species roosts in cavities or hollows of old trees (eucalyptus and oak/CA bay woodland), as well as under the eaves of the old structures in the northern part of the property. This species has a moderate likelihood of occurring onsite. • San Diego woodrat (Neotoma lepida intermedia; species of special concern) occurs in coastal scrub, chaparral and various woodland habitats in the region. Woodrats can occur in and around rock outcroppings and on slopes with good shrub or tree cover. Suitable habitat was identified in the coast live oak/CA bay woodland habitat as well as in the coastal scrub/chaparral habitat in the southern half of the project site. Wood rat nests were observed in the woodland and scrub/chaparral zone in the upper reaches of Drainages 1 and 2. The species has a high likelihood of occurring on the property. The proposed project, however, would not develop in these areas and therefore, would not impact this species. • Steelhead (Oncorhynchus mykiss irideus; federal threatened and species of concern) are known to occur in San Luis Obispo Creek and several of its tributary drainages with fresh, fast flowing cool water. Froom Creek is identified by the USFWS as critical habitat for the species, and the upper reach of Froom Creek has a known population of steelhead (potentially land-locked). It is unknown if steelhead in the upper reaches of Froom Creek make their way through the project site and into San Luis Obispo Creek. It is highly likely that during the winter storm season when high flows are present in the onsite portion of the creek, that steelhead could be moving through the site to areas up or downstream with suitable habitat. The onsite reach of Froom Creek is a dry channel for most of the year with flowing water present only following large storm events. Water flows recede quickly, and prolonged pools are poorly represented in the onsite portion of creek. Therefore, no perennial aquatic habitat is present that could support steelhead within the project boundaries. A high likelihood exists that this species could move through the site when flowing water is present, but would not be expected to persist or spawn within the project boundaries. • Townsend’s western big-eared bat (Corynorhinus townsendi townsendi; species of special concern) is known to occur in a variety of habitats in coastal California. They regularly forage along riparian corridors and roost in caves or buildings with cave-like features. No caves are present onsite for roosting, but old buildings (eaves of structures and the barn) in the northern part of the project site could potentially provide suitable roosting habitat for this species. The onsite grasslands, scrub (both coastal and riparian) and woodland habitats would be expected to provide suitable foraging habitat for the species. It has a moderate likelihood of occurring onsite. • Western mastiff bat (Eumops perotis californicus; species of special concern) is known from open, arid habitats including coastal scrub/chaparral, grasslands and various woodlands. It typically roosts in crevices in cliff faces, buildings, tall trees and tunnels. Suitable foraging habitat occurs throughout the varied plant communities onsite, and this species could roost in large trees with overhangs and cavities as well as under the eaves of buildings in the northern part of the project site. It has a moderate likelihood of occurring KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 34 onsite. • Western red bat (Lasiurus blossevilli; species of special concern) is another species of bat that forages in open areas and roosts in tall trees. Suitable foraging habitat was identified in onsite grasslands, and potential roosting habitat was identified in larger trees such as eucalyptus, coast live oak and sycamore mapped on the property. It has a moderate likelihood of occurring onsite. • Yuma Myotis (Myotis yumanensis; special animal) is a species of bat known to occur in riparian, scrub/chaparral and various arid habitat types near permanent water sources. It roosts in trees (hollows/cavities), rock crevices, mines, caves and man-made structures (eves of buildings, barns, etc.). Potential foraging habitat was identified over the entire project site, and suitable roosting habitat was identified in large trees and in the eaves of structures in the northern part of the project site. This species has a moderate likelihood of being encountered on the project site. Based on the information provided above and in the table included as Appendix B, the special status wildlife listed in the below table have a moderate or high likelihood of occurring in the specified habitats observed onsite. Table 2. Special Status Wildlife Potentially Occurring Onsite. Species Suitable Habitat on Project Site American badger (moderate) Grassland, scrub/chaparral, oak/CA bay woodland California horned lark (moderate) Grassland (nesting) Cooper’s hawk (high) Eucalyptus, sycamore, Oak/CA bay woodland (nesting) Hoary bat (moderate) Oak/CA bay woodland (roosting) Loggerhead shrike (moderate) Scrub/chaparral (nesting) Pallid bat (moderate) Eucalyptus, sycamore, oak/CA bay woodland, buildings (roosting) San Diego Woodrat (high) Scrub/chaparral, oak/CA bay woodland Steelhead trout (high) Froom Creek (movement corridor) Townsend’s western big-eared bat (moderate) Buildings (roosting) Tri-colored blackbird (moderate) Calle Joaquin wetland (nesting) Western mastiff bat (moderate) Eucalyptus, sycamore, oak/CA bay woodland, buildings (roosting) Western red bat (moderate) Eucalyptus, sycamore, oak/CA bay woodland, buildings (roosting) White-tailed kite (moderate) Eucalyptus, sycamore, oak/CA bay woodland (nesting) Yuma myotis (moderate) Eucalyptus, sycamore, oak/CA bay woodland, buildings (roosting) As stated above, CRLF, western pond turtle, Coast Range newt, and two-striped garter snake are known from the region. Given Froom Creek’s inconsistent flow regime, and series of focused day and night surveys of onsite aquatic habitat, these species are not expected to occur within the study area based on the lack of regular seasonal aquatic habitat. Under above average rainfall years when Froom Creek is flowing for a prolonged period and seasonal in-channel pools persist for at least 10 weeks, it is possible, albeit unlikely, that these species could find their way onto the site. Furthermore, seasonally ponded water along Calle Joaquin could also potentially provide seasonal habitat for these highly aquatic species, however, the high concentrations of crayfish and proximity to urban land uses and lack of connectivity to SLO Creek reduces the quality of this habitat. KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 35 4.0 CONCLUSION The Froom Ranch is situated in a biologically rich area of San Luis Obispo County composed of a mosaic of non-native and native grasslands, coast live oak/California bay woodland and coastal scrub/chaparral habitats bisected by drainages in the northeastern flank of the Irish Hills of the San Luis Range. Froom Creek traverses the site in a mostly north to south direction and joins San Luis Obispo Creek south of the site before flowing to the Pacific Ocean in Avila Beach. Wetland habitat occurs along the unnamed tributary drainages to Froom Creek, and in flat grassland areas where surface and subsurface water (groundwater) is impounded by LOVR and Calle Joaquin. The LOVR Roadside Channel, lower reach of Froom Creek, and Drainage 4 also contained riparian habitat composed of an arroyo willow monoculture. The most significant biological resources present onsite are the drainage features (i.e.: Froom Creek and Drainages 1, 2, 3, and 4) and associated wetland and riparian habitats, and the native serpentine bunchgrass grassland and serpentine rock outcrops supporting a suite of special status plant species, many of which are endemic to the San Luis Obispo area. Non-native annual grassland was the dominant plant community on the study area, primarily occurring in the flatter portions of the site where past disturbances such as cattle/horse feeding has occurred. Introduced perennial grassland composed of a monoculture of reed fescue was also present on the heavy clay soils in southern part of the site. The upper terrace in the southwest contained native serpentine bunchgrass grassland where rock outcrops and thinner, less developed soils were present. The wetland, riparian, and native bunchgrass grassland habitats delineated on the habitat map were identified as special status natural communities. Occurrences of special status plants were identified within the study area and their locations shown on Figure 7, the Special Status Plant Occurrence Map. Nine of the special status plants are California Rare Plant Rank (CRPR) 1B species, and one is a CRPR 2 species. CRPR 2 means that the species is rare in California but more widespread elsewhere. The federal and state endangered and CRPR 1B Chorro Creek bog thistle was also identified onsite, and was confined to wetland areas in Drainages 1 and 2 in the southwestern part of the study area. CRPR 4 species, such as Cambria morning glory and Palmer’s spineflower, are on a watch list and are relatively common in the project area, and therefore, should not meet the rarity threshold defined under CEQA. No special status wildlife were observed onsite, but Froom Creek could potentially provide a movement corridor for the federal threatened southern steelhead between upstream breeding areas and San Luis Obispo Creek when flowing water is present. Focused surveys for CRLF in 2018 confirmed this species is not present onsite. The analysis identified other special status wildlife (see Table 2) that could potentially occur in specific parts of the study area. The project includes varying levels of development and two important drainage components, the restoration of Froom Creek and construction of an offsite detention basin. With development, the proposal is to restore Froom Creek to a more historic drainage pattern where it will flow east across the site toward Los Osos Valley Road before it curves to parallel the Calle Joaquin corridor on the border of the site’s primary wetland feature. The restored Froom Creek corridor will convey flows from the project and the offsite upper reaches of the existing creek to the southeast corner of the property to connect to the existing creek bed that ultimately leads to a double box culvert going under Calle Joaquin and Highway 101. The restored Froom Creek corridor onsite would include a low flow channel and a large overbank area to convey larger flows. The low flow channel will provide a meandering conveyance designed KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 36 to create pools and riffle complexes and terraces throughout the onsite reach. At the Calle Joaquin wetlands, an overbank area is proposed where the creek bank will flatten out allowing flows from storms larger than a two–year event to migrate into the existing wetland. The Calle Joaquin wetland area is expected to be enhanced to create a large contiguous wetland feature directly abutting Froom Creek. Another drainage component of the proposed development plan is to remove the existing Irish Hills Plaza basin and replace it with a water quality feature (a channel similar to the current treatment feature on the Irish Hills Plaza site) between the Home Depot development and Specific Plan area and a new off-site basin. The proposed water quality features are expected to be adequate to meet storage volume of runoff consistent with regulatory agency requirements for the developed project as well as storage volume to accommodate the Irish Hills Plaza. It would be constructed to mirror the vegetation composition and structure present in the current Irish Hills Plaza basin.

Likelihood of Encounter Onsite California condor Gymnogyps californianus E/E/-- Roosts in cliffs or ledges; feeds in open areas up to 100 miles from roost. No suitable roosting or nesting habitat on-site, but could forage in grasslands as a very rare transient. Unlikely to occur. Not expected California homed lark Eremophila alpestris actia --/WL/-- Sparse coastal sage scrub and grasslands. Suitable foraging and nesting habitat in grasslands on- site. Could occur. Moderate California least tern Sterna antillarum browni E/E/-- Nests along coast from San Francisco Bay to northern Baja California. Nests on sandy beaches, alkali flats, landfills or paved areas. No suitable habitat present. Not expected to occur. Not expected Cooper’s hawk Accipiter cooperii --/WL/-- (nesting) Wooded areas. Nests in tall trees and often hunts around human structures. Potentially suitable nesting habitat present in oak/bay woodlands and eucalyptus/sycamore trees on-site. Could also forage across the site. Could occur. High Ferruginous hawk Buteo regalis --/WL/-- (nonbreeding/ wintering) Open grasslands, sagebrush flats, desert scrub, low foothills and fringes of pinyon-juniper habitats. Eats mostly lagomorphs, ground squirrels and mice. Suitable foraging habitat present in grasslands on-site, however this species typically does not nest in California. Could occur as a seasonal transient during fall/winter months. Low Golden eagle Aquila chrysaetos --/WL, FP/-- (nesting & nonbreeding/ wintering) Nests on cliffs and rocks and forages in open country, grasslands. Suitable foraging habitat in grasslands on-site. Unlikely to nest on the property, but rock outcroppings and cliff faces in the upper elevations outside the study area could be used for nesting. Low Loggerhead shrike Lanius ludovicianus --/SSC/-- (nesting) Nests in shrubs in coastal sage scrub and chaparral habitats or in trees that overlook grasslands; preys over semi-open habitats and feeds primarily on large insects and often skewers prey on a barb or thorn to cache for later feeding. Suitable woodland, grassland, and scrub habitat present for foraging and nesting. Could occur. Moderate Merlin Falco columbarius --/WL/-- (nonbreeding/ wintering) Nests outside of California; forages in a variety of habitats. Uses clumps of trees or windbreaks for roosting. Suitable foraging habitat present on-site. Could occur. Low Northern harrier Circus cyaneus --/SSC/-- (nesting) Forages and nests in grasslands and marshes. Requires large expanses of habitat for foraging. Suitable habitat present onsite for this species as the grassland habitat is expansive and connected to large open space. Observed foraging across the site, but no signs of nesting behavior. Could occur. Low Prairie falcon Falco mexicanus --/WL/-- (nesting) Catches pray in air and in open ground in grasslands. Nests in cliffs overlooking large areas. No nesting habitat present, but rocky outcrops in hills outside study area could potentially support nesting activities. Potential foraging habitat present on-site. Unlikely to occur. Low KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. B - 14 Appendix B. Special-Status Biological Resources Table Species Status* Fed/CA/CRPR Habitat Requirements Suitable Habitat Present or Detected in Study Area? Likelihood of Encounter Onsite Purple martin Progne subis --/SSC/-- (nesting) Nests in cavities of large trees in oak and riparian woodlands, and low elevation coniferous forests; rare; usually found near water. Suitable nesting habitat present in oak woodland and marginal habitat present in riparian habitat along LOVR. Could occur. Low Sharp-shinned hawk Accipiter striatus --/WL/-- (nesting) Prefers riparian plant communities, but can be found in pine and oak woodlands on north-facing slopes. Potentially suitable foraging and nesting habitat in oak//bay woodland and large trees present onsite. Could occur. Low Tricolored blackbird Agelaius tricolor (nesting colony) C/SSC/-- (nesting colony) Found near freshwater habitats where it nests in emergent freshwater or riparian vegetation. This species prefers nesting in dense thickets of cattails and tules. Due to their highly colonial nature, nesting areas must be large enough to support a colony of about 50 pairs. No suitable nesting habitat present in onsite detention basins or along the Froom Creek corridor. While a patch of tules is present along Calle Joaquin the area does not appear to be large enough to support nesting tricolored blackbirds. Not observed during surveys and unlikely to nest within the study area. Could occur as an uncommon transient and potentially nest onsite should the tule patch enlarge. Moderate Western snowy plover Charadrius alexandrinus nivosus T/SSC/-- (nesting) Sandy beaches, salt pond levees or shores of large alkali lakes. Sandy, gravelly or friable soils required for nesting. Federal listing refers only to the Pacific coastal population. No suitable habitat present. Not expected to occur. Not expected Western yellow-billed cuckoo Coccyzus americanus occidentalis C/E/-- (nesting) Nests and forages in dense lowland riparian vegetation during summer. Marginal habitat present in onsite riparian habitat along OVR. Last CNDDB record for the County was in 1921, and given the riparian habitat is comprised of a thin band of willows along a busy road, it is unlikely that this species would nest onsite. Low White-tailed kite Elanus leucurus --/FP/-- (nesting) Riparian woodlands near agricultural fields; forages over open grasslands and scrub. Suitable nesting habitat in oak, bay, eucalyptus and sycamore trees on-site, with good quality foraging habitat in grasslands throughout the Ranch. Not observed during surveys and no stick nests observed that could be used by this species for nesting activities. Known to occur further north of the site in the Los Osos Valley, and could occur onsite during foraging activities. Could also potentially nest onsite in the future. Moderate Yellow warbler Dendroica petechia brewsteri --/SSC/-- (nesting) Riparian plants, prefers willows, cottonwoods, aspens, sycamores and alders for resting and foraging. Marginal habitat is present in willow riparian area along the LOVR ditch, especially considering the well developed riparian corridor along San Luis Obispo Creek to the east. Could potentially occur in more dense riparian habitat but unlikely to nest onsite given disturbance along LOVR. Low MAMMALS American badger Taxidea taxus --/SSC/-- Friable soils and open, uncultivated ground for denning. Preys on burrowing rodents such as groundsquirrels. Suitable habitat is present in grassland on-site, but heavy clay soils likely preclude badgers from being regular residents onsite. No dens or large ground squirrel colonies observed within the project area. Could potentially occur as a transient across the site.

The investigation covered the Froom Ranch (APNs 067-241-030, 067-241-031), and a small portion of property owned by the Mountainbrook Church, which generally includes areas at the southwest side of Los Osos Valley Road (LOVR) and north of Calle Joaquin, in San Luis Obispo County, California. This assessment followed the U.S. Fish and Wildlife Service (USFWS) Revised Guidance on Site Assessments and Field Surveys for the California Red-legged Frog (USFWS 2005), and is a compilation of information received from regulatory agencies, literature reviews, and field work on the study area conducted by KMA over a two year period. A Biological Resources Inventory Report (BRI) prepared by KMA in January 2016 for the project provides background information referenced herein including a characterization of existing conditions, plant community mapping, and results of floristic and tree inventories. A special status species evaluation was also included in the BRI, and special status wildlife that could potentially occur onsite were identified based on a habitat suitability analysis. The BRI concluded that Froom Creek and the tributary drainage onsite do not appear to support suitable aquatic habitat with a sufficient hydroperiod for CRLF breeding, but that this species could potentially move onto the site from known occurrences in the region during periods of above average rainfall when seasonal aquatic habitat persists into the summer and fall months. As part of the ongoing regulatory agency consultation process, the USFWS in an August 14, 2017 letter from Ms. Julie Vanderwier to Ms. Shawna Scott with the City of San Luis Obispo’s Community Development Department, requested that a Site Assessment for CRLF be completed for the property. The purpose of the Site Assessment is to determine whether suitable aquatic habitat capable of supporting the federal threatened CRLF is present onsite, and if protocol-level surveys are warranted to accurately determine presence or absence to support the proposed project’s environmental review process. The following report details the methods and results of the site assessment, and is intended to build on the information contained in the BRI for the USFWS to make a determination if additional surveys are warranted. 1.1 Site Location and Description The Froom Ranch Specific Plan Area consists of two parcels located at 12165 and 12393 Froom Ranch Way, totaling approximately 111 acres (APN 067-241-030 and 067-241-031) currently within unincorporated San Luis Obispo County adjacent to City of San Luis Obispo city limits (please refer to Figures 1 and 2). It also includes a southern “spur” where a flood control basin would be constructed on neighboring property owned by the Mountainbrook Church. The site is located immediately west of Los Osos Valley Road between Highway 101 and the Irish Hills Plaza. It is currently a working cattle/horse ranch that supports a variety of habitat types including: grasslands (both native bunchgrass and non-native annual), oak woodland (with California bay trees), coastal scrub/chaparral, serpentine outcrops, and seasonal and perennial wetlands that are primarily associated with drainage features. Ruderal or disturbed areas are also present and consist of existing developed areas as well as constructed stormwater basins that are part of the Irish Hills Plaza development. Froom Creek, which flows to San Luis Obispo Creek via a culvert under Calle Joaquin and Highway 101, and three unnamed tributary drainages are also present onsite.

Average annual precipitation in the region of the site is approximately 22 inches, most of which falls between November and April. On-site elevations range from approximately 110 feet above mean sea level (MSL) at the lowest point near the intersection of Calle Joaquin and LOVR, to approximately 410 feet MSL on the upper western hillslopes adjacent to the Irish Hills Natural Reserve. Soils are primarily Cropley clay in the lower elevations of the site, with large areas of serpentine outcrops and serpentine influenced soils present in the higher elevations of the property to the west. 1.2 Proposed Project Description The proposed Froom Ranch development is envisioned as a residential project with some commercial development in the northeast corner of the site closest to the adjacent Irish Hills Plaza. Permanent open space is proposed to occupy about 51% of the Froom Ranch site. The project is divided into two main components: The Madonna Froom Ranch and The Life Plan Community (also known as the Villaggio). The Madonna Froom Ranch would be situated in the northern portion of the Specific Plan Area, just south of the Irish Hills Plaza. It will contain a mix of commercial and residential land uses, and include a hotel and trailhead park. The park will provide a staging area and connection to open space trails within the City’s Irish Hills Natural Reserve. The Villaggio project would provide a variety of different unit types for independent senior housing and include access to assisted living, memory care, and skilled nursing. A recreational facility, restaurants, and movie theater are also planned in this community. For a detailed project description, please refer to the Froom Ranch Specific Plan prepared by RRM Design Group. 2.0 METHODS 2.1 Background Information The study area for this CRLF Site Assessment included the approximately 111-acre Froom Ranch property, and an additional plus or minus 15 acres on the adjacent Mountain Brook Church where a future storm water detention basin would be constructed. Aquatic habitat features within a one- mile radius of the property were also included and generally evaluated in the assessment. As part of the BRI, KMA biologists reviewed site-specific aerial photographs and maps from studies in the region (Google Earth and ESRI, the U.S. Geological Survey San Luis Obispo and Pismo 7.5-minute quadrangles, and the City of San Luis Obispo Irish Hills Natural Area Conservation Plan Update from 2011). The California Department of Fish and Wildlife Natural Diversity Data Base (CNDDB; 2017) was queried for CRLF records within five miles of the site, with increased focus within a one- mile (1.6-kilometer) radius of the site. Museum records (Santa Barbara Museum of Natural History, California Polytechnic State University San Luis Obispo, and University of California at Berkley) were also searched online, and other available biological reports from studies conducted in the region such as the LOVR and Highway 101 Interchange project were reviewed. Please refer to the literature cited in the BRI for further detail. In addition, City of San Luis Obispo Natural Resources Manager, Robert Hill, and Biologist, Freddy Otte, were consulted regarding ongoing herpetological field work on the Waddell property located in the headwaters of Froom Creek to the south of the study area. 2.2 Site Assessment Surveys KMA conducted extensive field work on the Froom Ranch over a two year period that spanned from 2015 to 2017. All drainage features onsite were walked on numerous occassions and areas of KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 5 instream seasonally ponded of flowing water were assessed and mapped to aid in determining the site’s potential to support CRLF and other special status aquatic species. Aquatic habitats encountered on the property were characterized (water body type, estimated persistence of water, vegetation, water depth, bank full depth, stream gradient, substrate, and description of banks) as indicated in the protocol site assessment datasheet. Potentially suitable areas were examined for presence of American bullfrogs (Lithobates catesbeianus) and other aquatic predators such as crayfish (likely the genus Pacifastacus). For the BRI, vegetation communities were mapped following the Sawyer, Keeler-Wolf and Evens (2009) habitat classification system in association with Holland’s 1986 classification system. As part of the CRLF site assessment, habitats/vegetation communities within the one-mile radius around the study area were characterized using aerial photographs, topographic maps, and visual surveys conducted from public roads and public open space areas. Aquatic habitats, land uses, and any potential barriers to CRLF movement were noted. 2.3 Qualifications of Surveyor Kevin Merk conducted the site assessment with support from other KMA biologists, and was the primary author of this report. He has hundreds of hours conducting site assessments and protocol level surveys over the last 25 years, and is able to identify all life stages of CRLF. Mr. Merk has also been authorized by the USFWS under Section 7 of the Endangered Species Act (via specific biological opinions) to capture and handle CRLF for various construction/development projects in the Central Coast region of California. 3.0 RESULTS 3.1 Known Occurrences of California Red-legged Frogs in the Region The study area is within the historic range of the CRLF (Jennings and Hayes 1994, Stebbins 2003), but is located outside USFWS designated CRLF critical habitat. Critical Habitat Unit SLO-3 is located to the north of the site (USFWS Critical Habitat Mapper, 2017). Please refer to Figure 3, the CRLF Occurrence Map for CNDDB records in the project area as well as the location of critical habitat. The results of the CNDDB query and consultation with the City of San Luis Obispo revealed one CRLF occurrence within one (1) mile (1.6-kilometer) of the property. This record is dated 2006, and documents one CRLF observed within the City of San Luis Obispo’s wastewater treatment pond located on the east side of the Highway 101 corridor (Occurrence No. 895). The next closest record is from 2017 biological surveys on the City of San Luis Obispo’s recently aquired Waddel property. The observation location is approximately 2.3 miles to the west of the study area boundaries within the upper Froom Creek watershed. Other documented occurrences in the project region are on the southern flank of the Santa Lucia Mountains from 1939 in Brizzolari Creek, approximately 3.8 miles to the north of the property (Occurrence No. 1341), and from 1998 at the Avila Beach Golf Resort, approximately 4.6 miles to the south (Occurrence No. 303). Please refer to Figure 3 for the locations of these and other occurrences within one and five mile radii of the site.

The property is situated on the northeastern flank of the Irish Hills, with developed urban areas on the north, east and south boundaries. To the west is undeveloped open space in the City’s Irish Hills Natural Reserve. Seasonal drainage features present include Froom Creek and three small tributary drainages, and the LOVR roadside ditch. The site contains the Irish Hills Plaza Storm Water Basin that handles surface runoff from neighboring development to the north. The basin is located in upland areas between the Froom Creek channel and Los Osos Valley Road, and a small ditch directs drainage water when present into the LOVR roadside ditch, which terminates into the Calle Joaquin wetland further south. As detailed in the BRI, the dominant habitat types observed within the study area included annual (non-native) grassland, serpentine bunchgrass grassland on the higher elevation hillsides, coastal scrub/chaparral on steeper rocky slopes, coast live oak woodland on north facing slopes and along drainages, arroyo willow riparian scrub along the LOVR ditch, and developed/disturbed areas primarily in the northern part of the property. Areas of non-native tree plantings, including blue gum eucalyptus (Eucalyptus globulus) and pepper trees (Schinus molle) are also present. Site assessment data sheets were prepared for the Froom Ranch property to characterize potentially suitable habitat areas (please refer to Appendix A). Photographs of the potential habitat areas described herein are provided in the Photo Plate included as Appendix B. The Habitat Map from the BRI is included as Appendix C, and the Wetland Delineation Overview Map (KMA, 2015) is included as Appendix D to help identify location of drainage features, as well as photo point locations. The following provides a summary and brief characterization of the areas that were the focus of the assessment. Froom Creek, an episodic drainage feature, traverses the site generally from north to south, and ultimately passes beneath Calle Joaquin and Highway 101 through a concrete box culvert (over 300 linear feet) before joining San Luis Obispo Creek to the south. The section of Froom Creek within the site is sparsely vegetated, and was composed of a dry cobble bed with bare soil banks and patchy occurrences of grassland species. It was completely dry during the 2015 and 2016 surveys. Flowing water was present in January 2017 following a series of large storm events, and then flow subsided and dried by March into April 2017. No willows or other riparian vegetation is present within this portion of the channel, but a small area (less than 12 inches deep) of instream ponding was observed near the Froom Ranch property southern line near the Drainage 1 confluence. Due to the lack of persistent water (i.e., it did not have any water with a depth of 24 inches for longer than 10 weeks) and any vegetative cover, it does not appear to provide suitable habitat for CRLF. Three ephemeral tributary drainage features are present in the southern portion of the study area that are hydrologically connected to Froom Creek. Small areas of ponded water with adjacent wetland vegetation were observed in the lower reach of the southernmost tributary drainage (Drainage 1 near the confluence with Drainage 2). At this location, a narrow in-channel, seasonal ponded area was observed that appears to be supported by springs or seeps originating on adjacent hillsides. The ponded area consisted of two connected pools less than 16 inches in depth, and covered a total area of approximately 150 square feet (6 feet wide by approximately 25 feet long). The canopy cover was high and consisted of large coast live oak (Quercus agrifolia) and California bay (Umbellularia californica) trees, with no low overhanging willows or emergent vegetation KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 8 present. Ponded areas were dominated by bare mud/silt and rock, with vegetated areas perched in the flatter area beyond the Drainage 1 top of bank along the lower reach of Drainage 2. Wetland vegetation observed in this flat area included spike-rush (Eleocharis macrostachya), tall flatsedge (Cyperus eragrostis), seep monkeyflower (Mimulus guttatus), water parsley (Oenanthe sarmentosa), rabbitsfoot grass (Polypogon monspeliensis), and Bermuda grass (Cynodon dactylon). Some common duckweed (Lemna minor) was present in the Drainage 1 channel below ponded areas. The ponded areas at bank full conditions could be as much as six (6) feet deep, but this condition would be unlikely due to the small watershed feeding the tributary, and steep nature of this feature leading towards Froom Creek. Due to the presence of shallow ponding, and limited water duration through early summer months, the ponded areas identified along Drainage 1 are considered to provide low to marginal quality habitat for CRLF. The shallow depth of the instream ponding and lack of emergent vegetation would not be expected to provide suitable refuge habitat for CRLF, and any individuals that potentially found this site, would likely be subject to predation since racoon (Procyon lotor) tracks were regularly observed in this area. If the site was close to a more permanent water body that provided potential breeding habitat, the surrounding oak woodland and bay tree habitats could provide refugia for estivation during the summer but that is highly unlikely given the limited aquatic resources on the site. While not completely isolated from San Luis Obispo Creek where CRLF were observed previously, individuals would have to traverse the over 300 foot long concrete culvert and move up the dry cobble Froom Creek channel to find seasonal water at this location. If a breeding population was near by, Drainage 1 could possibly be used by frogs during dispersal, but no suitable habitat for this species is present to the west, making it unlikely that CRLF would move back and forth into or through this area. Further, ponded water in Drainage 1 would not be expected to provide suitable breeding habitat due to lack of sufficient hydroperiod (water during most years does not persist for over 10 weeks). Calle Joaquin Wetland. Calle Joaquin and Los Osos Valley Road impound surface water alongside the roadways’ eastern and southern sides on a seasonal basis. While culverts were installed to drain high flows under Calle Joaquin into a riparian drainage area across the street and then toward San Luis Obispo Creek to the south, soils remain saturated for a long enough duration to support perennial wetland habitat. The ponded area observed along Calle Joaquin in the winters of 2015 and 2016 were less than 12 inches deep, but contained a predominance of wetland vegetation and several dense clumps of bulrush (Schoenoplectus acutus). By the summers of 2015 and 2016 the areas contained marginal surface water ranging in depth from one to four inches in small pockets. During the winter rain season of 2017, ponded water observed in this area for a much longer time period (water was present through September 1, 2017) and averaged approximately 12 to 24 inches in depth. The deepest location observed in the spring 2017 supported upwards of 28 inches of standing water. As stated above, culverts in this area direct water under Calle Joaquin into a triangular riparian drainage area on the south side of Calle Joaquin, that is separated from San Luis Obispo Creek by a hotel, parking lot and Highway 101. It appears that the maximum depth of ponded water in the Calle Joaquin wetland would be approximately three feet before overtopping the curb and spilling onto the street. Adjacent upland areas to the Calle Joaquin wetland area consist of seasonal wetland habitat being overtaken by reed fescue (Festuca arundinacea) planted as forage. Due to the presence of sufficient water depth and emergent vegetation (primarily bulrush), this area would be considered potentially suitable habitat for CRLF. While it is less than 1,000 feet away from the observed CRLF occurrence in the City’s wastewater pond on the eastside of San Luis Obispo Creek, the Calle Joaquin wetland is separated from potentially suitable habitat within the San Luis Obispo Creek KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 9 corridor by urban development including Highway 101, an onramp, hotel, parking lot and Calle Joaquin. It is unlikely that CRLF could disperse overland across Highway 101, Los Osos Valley Road and Calle Joaquin onto the site. The triangular drainage area with riparian habitat on the south side of Calle Joaquin could also potentially be used by CRLF based on the presence of dense riparian and wetland vegetation and seasonal ponded water, eventhough it is primarily road runoff with unknown pollutants. Several biological and hydrologic studies have been completed in this general location for other projects, including the Calle Joaquin Road realignment, and the LOVR/Highway 101 interchange project. Focused protocol level surveys for listed branchiopods were also conducted for the Calle Joaquin Road realignment, and these surveys, even though focused on sampling for invertebrates, did not observe CRLF in the wetland area prior to the construction of Calle Joaquin. During this site assessment, Pacific tree frogs and one crayfish were observed in the Calle Joaquin wetland area. The dominance of perennial wetland vegetation, observed surface ponding into September, as well as review of historical aerial photographs obtained from Google Earth, suggests that the Calle Joaquin wetland site functions as a semi-perennial to perennial wetland, and therefore, contains potentially suitable habitat to support CRLF. The proposed project would not affect this area, and the Froom Creek realignment would be situated to maintain the hydrology to support wetland habitat in this part of the property. Irish Hills Plaza Stormwater Detention Basins. Construction of the Irish Hills Plaza included two large stormwater detention basins, immediately adjacent to each other and separated by an earthen berm. The basins were constructed between mid-2006 and mid-2007. The drainage basins release overflow water to the LOVR Roadside Ditch via a storm drain outfall into a constructed swale. During large storm events, the basin is designed to discharge water into the wetland/meadow area along Calle Joaquin via a concrete spillway on the south side of the main basin. Otherwise, water leaves the basin through evaporation and ground percolation. A large french drain system was also constructed around the perimeter of the basin to help maintain wetland vegetation along Calle Joaquin (personal communication with John Madonna). Google Earth historical aerial imagery indicates that these basins have been actively managed, with grading of the basins performed between April and August 2013, disturbing soil and removing vegetation. Under the proposed Froom Ranch development plan, these drainage basins would be removed, and runoff would be redirected into new constructed features including a larger basin proposed on the neighboring Mountainbrook Church property adjacent to Froom Creek. During the August and September 2017 site assessment field visits, the north basin featured shallow ponding (average 4-8 inches in depth) throughout much of the basin floor. Vegetation was dominated by obligate wetland plants such as cattail, spikerush and small fruited bulrush (Scirpus microcarpus) along with brown-headed rush and rabbitsfoot grass. The south basin was densely vegetated, but did not have ponded water or the predominance of obligate wetland plants, though signs of recent seasonal ponding were evident in the form of algal mats, cracked soil and surface salt deposits. Dominant vegetation included facultative wetland species such as creeping rye (Elymus triticoides), brown-headed rush, and reed fescue with patches of cattails present in several areas where saturation appears to persist In the more barren patches exhibiting salt crust and/or algal mats from recent drying, prickly sow thistle (Sonchus asper; a facultative wetland species) frequently occurred. KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 10 Historic aerial photos reviewed on Google Earth show that the north and south basins both dry out seasonally in most years. The high rainfall in 2017 may be responsible for the continued ponding seen in the north basin into early September 2017, as well as ponding that appears to have lasted into the early summer in the south basin, based on presence of algal mats and salt deposits. The wetland plant species currently dominating both basins suggest semi-perennial wetland hydrology, but aerial photos taken as recently as September 2016 show the vegetation in both basins as almost entirely brown, with no visible surface ponding. The seasonal drying pattern coupled with the physical separation from known occurrences (i.e., the basin was constructed in an upland grassland area away from Froom Creek and the Calle Joaquin wetland) makes it unlikely that CRLF would find the stormwater basins even if they could disperse across Highway 101 and urban areas from San Luis Obispo Creek. Furthermore, with the shallow ponded water present in the basins, it would be unlikely to support breeding habitat for the species since they would be easily preyed upon by larger animals, and a regular hydroperiod of at least 10 weeks does not appear to be present. The fact that the basins were constructed as recently as 2006-07, and then graded for maintenance in 2013, and are not naturally connected to areas of potential habitat in San Luis Obispo Creek, also make it unlikely that CRLF would be able to locate and utilize the basins for seasonal foraging or breeding habitat. Clearly the features do not have the necessary aquatic habitat required to maintain a sustained breeding population of CRLF since they are constructed features with periodic soil disturbance from grading to remove vegetation and accumulated debris and sediment. If the basins were constructed immediately adjacent to suitable habitat (such as the case for the City’s wastewater pond where the CRLF was observed in 2006), were not regularly maintained, and did not have significant movement barriers such as Highway 101 and LOVR in place, it is possible that CRLF could use it on a seasonal basis. 3.2.2 Areas Within One Mile of the Property The area surrounding the subject property consists primarily of developed urban lands to the north and south, and the Irish Hills Natural Reserve to the north and west. Please refer to Figure 4 for existing conditions and land cover types within the one mile study area. Commercial development along LOVR and Highway 101 to the east and south create a formidable barrier for CRLF should they be present in San Luis Obispo Creek or other nearby water bodies and drainage features such as Laguna Lake and Prefumo Creek. While one individual was observed at the City’s wastewater treatment facility on the east side of Highway 101, other focused surveys in the area, and in San Luis Obispo Creek, have been unable to locate CRLF in San Luis Obispo Creek (personal communication with Sage Institute, 2017). If a healthy breeding population was present in San Luis Obispo Creek, it is possible that CRLF could disperse from breeding sites and move through the Froom Creek concrete box culvert under Calle Joaquin and Highway 101 and onto the property. However, it is a very long culvert (measured at over 300 linear feet) which likely would preclude small amphibian movement onto the site. It is also important to note that even if a CRLF were to use the culvert for movement, Froom Creek is a dry episodic drainage feature with no prolonged pools in the vicinity of the culvert. The first seasonal pool is not encountered until further onto the property near the confluence of Drainage 1 and Froom Creek. Even that seasonal in channel pond is short lived, does not have any vegetative cover, and any frog that found the feature would likely be preyed upon by racoon or other birds observed foraging in the area. As stated above, the Highway 101 corridor, LOVR, Calle Joaquin and associated commercial development present a significant barrier to CRLF dispersal from the north, south and east.

Tank Farm Rd. B r o a d S t . 1 in = 1,500 ft KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 12 stated above, given past studies in the region, it appears that CRLF occur in low numbers in the San Luis Obispo Creek corridor due to the lack of suitable breeding habitat. Recent study on the City-owned Waddell Property, identified what appears to be a breeding CRLF population in the upper reaches of Froom Creek to the northwest of the project site (personal communication with Robert Hill, 2017). At this location perennial or prolonged, slow moving water sources are available. This is roughly 2.3 miles from the edge of the northern proerty line, and the portion of Froom Creek between the site and observed CRLF occurrences is a highly ephemeral drainage channel with much of the channel and surrounding uplands covered in chaparral habitat that would not be easily traversed by dispersing individuals. Still it is possible that a CRLF could be washed downstream during the high flow events, such as those observed during January 2017. But as discussed herein, the portion of Froom Creek on the study area does not contain the necessary habitat attributes such as long lived, deep pools (24 inches or greater) of slow moving water with thickets of riparian shrubs, trees and emergent wetland vegetation to support foraging or CRLF breeding activities. While seasonal foraging could be supported onsite or in relatively close proximity to the site, it appears that suitable habitat in the immediate project area is limited, and if CRLF are in fact present in San Luis Obispo Creek, they occur at low numbers. 3.2.3 Critical Habitat Designation The U.S. Fish and Wildlife Service designated critical habitat for CRLF in the region (Unit SLO-3). This unit is outside the study area, and no critical habitat attributes were observed within the study area. 4.0 CONCLUSION Typically, adult CRLF require dense, shrubby or emergent riparian vegetation closely associated with deep (greater than 24 inches) still or slow-moving water for breeding habitat. Well-vegetated terrestrial areas within a riparian corridor can provide important sheltering habitat during winter months when high flows are present. The 2015 and 2016 surveys were conducted during below average rainfall years, following severe drought conditions during the previous two years. The drought conditions experienced in the region likely had a significant impact on local amphibian populations and further restricted breeding and dispersal activities. The winter and spring of 2017 was an above average precipitation year, and flowing water was present in Froom Creek in January. In addition, areas of ponded water in onsite features identified on attached data sheets persisted longer than previously observed, but still, vegetation conditions did not change significantly. Based on the results of the site assessment, the most suitable habitat identified on the project site is located in the Calle Joaquin wetland. While we cannot completely rule out CRLF presence from this area, based on the high number of survey hours onsite to date coupled with the major dispersal barriers (i.e., Highway 101, LOVR and surrounding commercial development), CRLF are unlikely to move from San Luis Obispo Creek onto the site. Further, the Froom Creek culvert is very long, and would be a major undertaking for a CRLF to disperse over 300 linear feet through this culvert to access the site. Once onsite, the dispersing individual would need to locate suitable aquatic habitat to persist, and the site assessment confirmed there are no prolonged pools with appropriate depth and vegetative structure in the immediate area of the culvert or within Froom Creek and Drainage 1 on the project site that could support this species. KMA Froom Ranch Specific Plan Project California Red-Legged Frog Site Assessment JM Development Group, Inc. 13 The portion of Froom Creek on the property does not provide suitable aquatic habitat for the CRLF due to lack of regularly ponded water with a sufficient hydroperiod to support breeding or even foraging activities. Seasonal flows with regularity to support dispersal from nearby breeding areas (such as the upper Froom Creek observation on the Waddell Property), and suitable riparian and wetland vegetation along the channel also appear to be absent. The section of Froom Creek south of the Froom Ranch property on Mountainbrook Church property extending to Calle Joaquin also lacks sufficient hydroperiods, pool structure, and instream vegetation. The southern tributary channel identified as Drainage 1 contained marginally suitable habitat since it has some prolonged surface water present in a channel with a relatively high canopy of coast live oak and California bay. However, the water depth was not suitable since it was regularly observed at less than 18 inches, and dense shrubby vegetation cover such as overhanging willows and emergent wetland plants needed for refuge and cover from predators was also not present. The in stream ponding observed and shown in the attached photo plate, shows an open channel that would be easily accessed by predators such as racoon and other birds present in the area. The Irish Hills Storm Water Basin is a constructed feature in an upland area with an ephemeral ponding regime. In drought years such as 2015 and 2016, no ponding was observed. In 2017, prolonged surface water was present in the north basin into September, and a dense carpet of wetland vegetation was present. The periodic grading and removal of vegetation and sediment from this constructed feature, as well as the water source being from polluted parking lot runoff, also reduces the potential for CRLF presence. The heavily traveled Highway 101 and LOVR corridors create a significant barrier to dispersal from the north and east, including from the 2006 occurrence at the City’s wastewater facility. While CRLF have now been confirmed in the upper Froom Creek watershed, the site is roughly 2.3 miles from this occurrence and the creek corridor and surrounding chaparral vegetation would be challenging for dispersal of CRLF onto the property, especially when considering no suitable pool habitat is present within the study area boundaries. In addition, the areas of marginal CRLF habitat comprised of the lower reach of Drainage 1 did not have a suitable hydroperiod to support CRLF. While the Calle Joaquin wetland contained potentially suitable habitat for CRLF based on the presence of prolonged surface water and dense emergent vegetation. Based on the results of this assessment, it appears unlikely that CRLF could utilize any portion of the site based on its isolation from San Luis Obispo Creek and separation from known occurrences in the region by urban development and unsuitable habitat, and the landscape around the project site is not conducive to CRLF movement. The Calle Joaquin wetland contained potentially suitable habitat, and represents the only location onsite with a higher potential to support the species. Of importance, this area would be avoided by the future project, and maintained as permanent open space. The realignment of Froom Creek has been designed to increase areas of instream ponding on the site and maintain the wetland hydrology of the Calle Joaquin wetland. As such, future development of the Froom Ranch Specific Plan is unlikely to affect CRLF, especially with the incorporation of avoidance measures such as pre-construction clearance surveys and other best management practices implemented during construction of the new Froom Creek channel. 5.0 REFERENCES Bulger, J.B., N.J.

A Biological Resources Inventory Report (BRI) prepared by KMA in January 2016 for the project provided background information referenced herein including a characterization of existing conditions, and results of floristic and tree inventories. A special status species evaluation was also included, and special status wildlife that could potentially occur onsite were identified based on a habitat suitability analysis. The analysis concluded that since no vernal pool or suitable seasonal wetland habitat was present, and past focused surveys for listed branchiopods in the Calle Joaquin wetland area produced negative findings, species such as the federally threatened vernal pool fairy shrimp (Branchinecta lynchi; VPFS) were unlikely to occur onsite. Populations of VPFS have been identified to the east of the Froom Ranch property, primarily on the former Chevron Tank Farm property, which is within two miles of the study area. A 2013 recorded occurrence was also identified off Vachell Lane within one mile of the property. All occurrences are located to the east of Highway 101 in isolated wetlands and gentle swale complexes. As part of the ongoing regulatory agency consultation process, the U.S. Fish and Wildlife Service (USFWS) in an August 14, 2017 letter from Ms. Julie Vanderwier to Ms. Shawna Scott with the City of San Luis Obispo’s Community Development Department, requested that a vernal pool habitat assessment be completed for the property. The purpose of the vernal pool habitat assessment is to determine whether suitable seasonal pool habitat capable of supporting federal listed vernal pool branchiopods such as VPFS are present onsite that could potentially be impacted by future project development. This report details the methods and results of the vernal pool habitat assessment conducted on the proposed Froom Ranch Specific Plan project site. 1.1 Project Description The Froom Ranch Specific Plan Area consists of two parcels located at 12165 and 12393 Froom Ranch Way, totaling approximately 111 acres (APN 067-241-030 and 067-241-031) currently within unincorporated San Luis Obispo County adjacent to City of San Luis Obispo city limits (please refer to Figures 1 and 2). It also includes a southern “spur” where a flood control basin would be constructed on neighboring property owned by the Mountainbrook Church. The site is located immediately west of Los Osos Valley Road between Highway 101 and the Irish Hills Plaza. It is currently a working cattle/horse ranch that supports a variety of habitat types including: grasslands (both native bunchgrass and non-native annual), oak woodland (with California bay trees), coastal scrub/chaparral, serpentine outcrops, and seasonal and perennial wetlands that are primarily associated with drainage features. Ruderal or disturbed areas are also present and consist of existing developed areas as well as constructed stormwater basins that are part of the Irish Hills Plaza development. Froom Creek, which flows to San Luis Obispo Creek via culverts under Calle Joaquin and Highway 101, and three unnamed tributary drainages are also present onsite. The proposed Froom Ranch development is envisioned as a residential project with some commercial development in the northeast corner of the site closest to the adjacent Irish Hills Plaza. Permanent open space is proposed to occupy about 51% of the Froom Ranch site. The project is divided into two main components: The Madonna Froom Ranch and The Life Plan Community (also known as the Villaggio). The Madonna Froom Ranch would be situated in the northern portion of the Specific Plan Area, just south of the Irish Hills Plaza. It will contain a mix of commercial and Site Location ^_ ²1 in = 10,000 ft 0 1 20.5 Miles Figure 1 Site Location Site Location ^_ 1 in = 1,000,000 ft JM Development Group, Inc.

Vernal pools typically have high levels of native biodiversity, and some pools provide habitat for protected plant, crustacean, and amphibian species (Platenkamp 1998). Vernal pools and seasonal wetlands frequently tend to be small features, often 0.125 acre or smaller, and generally cannot be easily identified on aerial imagery unless the image is high resolution and the pools are filled with water at the time the aerial photograph is taken. Naturally formed vernal pools may occur singly or in complexes, with a series of depressions in close proximity, often connected by swales. Depending on the size of the pool and other environmental factors, a vernal pool may be inundated for a week or upwards of several months before completely drying. This seasonal ponding allows a suite of native flora and fauna that are highly specialized to persist in an area with a wide range of hydrologic conditions. While Holland (1986; Holland and Iain 1988) was historically the primary source for vernal pool taxonomy in the state of California, more recent studies have refined vernal pool classification based on the hydrogeomorphology and dominant vegetation (Ferren et al. 1996; Sawyer, Keeler-Wolf and Evens, 2009). Among the fauna that may utilize vernal pools are a group of small crustaceans in the class Branchiopoda, which includes the invertebrates commonly known as fairy shrimp and tadpole shrimp. Within the state of California, over 25 species of fairy shrimp and tadpole shrimp have been recorded, including five fairy shrimp and one tadpole shrimp that are federally protected as threatened or endangered under the federal Endangered Species Act (FESA). San Luis Obispo County is known to host several species of fairy shrimp, with most occurrences in the drier inland areas east of Paso Robles and onto the Carrizo Plain. Within and adjacent to the City of San Luis Obispo, two species of fairy shrimp have been recorded: Linderiella occidentalis (California linderiella), and Branchinecta lynchi (“vernal pool fairy shrimp” or VPFS). California linderiella is a state Species of Concern, and VPFS is federally listed as threatened (USFWS 1994). Populations of VPFS have been recorded at two sites within two miles of the Froom Ranch property, and include the former Chevron Tank Farm property and an adjacent parcel off Buckley Road and Vachell Lane (please refer to Figure 3, the CNDDB Occurrence Map). Although VPFS were once thought to occur only in the Central Valley of California, populations have now been identified as far north as the Agate Desert of southern Oregon and as far south as the Santa Rosa Plateau near Riverside in southern California. The VPFS has the widest geographic range of the federally-listed vernal pool crustaceans, but it is seldom abundant where found, especially where it co-occurs with other species of fairy shrimp (USFWS 2003; Ericksen and Belk 1999).

Like most other fairy shrimps, the vernal pool fairy shrimp lacks any substantial anti-predator defenses and does not persist in waters with fish (King et al. 1996; Eriksen and Belk, 1999). When the temporary pools dry, offspring persist in suspended development as desiccation-resistant embryos (commonly called cysts) in the pool substrate until the return of winter rains and appropriate temperatures allow some of the cysts to hatch (Eriksen and Belk, 1999). Vernal pool habitats form in depressions above an impervious substrate layer, or claypan/duripan, usually in alluvial fans and terraces (Vollmar, 2002).” “…The thermal and chemical properties of vernal pool waters are two of the primary factors affecting the distributions of specific fairy shrimp species (including the vernal pool fairy shrimp), or their appearance from year to year. Different species may appear in pools from one year to the next, depending on whether the pools fill at a different time of the year. Based on hatching and life history requirements, species may also appear in succession during one season as conditions change within the pool (Simovich and Fugate 1992; Eriksen and Belk 1999)… Active vernal pool fairy shrimp die off when water temperatures get too warm (Helm 1998). In years with low amounts of precipitation or atypical timing of precipitation, (or in substandard habitat) vernal pool species may die off before reproducing (Eriksen and Belk 1999). Adult VPFS are usually less than one (1) inch in length, and are very fragile. Their cysts are tiny, from 0.15 to 0.4 mm in diameter, and are very resilient, especially when dry (Eriksen and Belk 1999). Animals moving through vernal pools, drinking and feeding from them, may aid in dispersing VPFS to new locations: “Long-distance dispersal of anostracan cysts is thought to be enabled by waterfowl and other migratory birds that ingest cysts, and by animals that provide for movement of mud and cysts in feathers, fur, and hooves…” (USFWS 2007) VPFS populations can exist in many types of topographic depressions that pond water seasonally, including ponds that are not naturally-formed vernal pools, if the conditions provide the hydrologic regime, thermal and chemical properties the species requires. A study which sampled over 4,000 California seasonal wetlands identified endemic fairy shrimp and tadpole shrimp in wetlands ranging in type from natural freshwater and alkaline vernal pools to rock outcrop pools to percolation test pits, pools formed in dirt and gravel-based railroad rights of way by vehicular traffic, roadside ditches, stock ponds and more (Helm 1996). In northern San Luis Obispo County, at Camp Roberts National Guard Training Installation, VPFS monitoring programs recorded recurring populations of VPFS in old mortar holes and tank ruts on claypan soils (U.S. DOD and CA ARNG 1998). Simovich’s 1998 paper on “Crustacean Biodiversity and Endemism in California’s Ephemeral Wetlands” summarized characteristics specific to ephemeral water bodies that are missing in more perennial water bodies. The key characteristics identified that restrict or limit anostracans, such as VPFS, to ephemeral water bodies include: lack of fish; predation pressure from other species being KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 7 delayed until after VPFS reproduction is largely complete; and the cyst storage bank in the ephemeral pool, with VPFS cysts hatching at different times and different years, improving the species’ chances of survival (Simovich 1998). Conversely, the following characteristics are indications that the location generally will not provide suitable habitat for listed large branchiopods: “Habitats that swiftly flow water (e.g., creeks, streams, and ephemeral drainages) or habitats that are semi-to-permanently inundated and support perennial populations of predators (e.g. bullfrogs, fish, and crayfish).” (USFWS 2015) 3.0 METHODS 3.1 Background Research Prior to conducting field work, KMA’s Principal Biologist, Kevin Merk, and Senior Biologist Julie Thomas reviewed pertinent background information from the general area. This included previous biological studies in the region and on the subject site, as well as the recently completed Biological Resources Inventory (KMA 2016). Numerous field hours were spent on the study area during the winter and spring months of 2015/2016 and 2016/2017 to characterize the nature and extent of drainage and wetland features subject to Clean Water Act and California Fish and Game Code requirements, which provided direct observation of onsite hydrology. Several Environmental Impact Reports, biology studies and wetland delineations completed for nearby development projects were also reviewed. Hydrologic studies, wetland mitigation plans and subsequent mitigation monitoring reports completed for the Home Depot project, which included portions of the study area, were also reviewed as part of the investigation. Local studies and documents reviewed for this vernal pool habitat assessment included the following: ¥ Madonna Eagle Hardware Environmental Impact Report (1998); ¥ Biological Resources Analysis Letter of Findings for the Los Osos Valley Road Improvement Project (Olberding Environmental, 2001); ¥ Wetland Restoration and Mitigation Plans Relating to the Froom Ranch/Home Depot Project (Olberding Environmental, 2002); ¥ San Luis Obispo Creek Watershed Enhancement Plan (Land Conservancy of San Luis Obispo County, 2002); ¥ Year 1 Wetland Monitoring Report for the Froom Ranch/Boysen Ranch Mitigation Sites (Olberding Environmental, 2003); ¥ Calle Joaquin Realignment Wetland Delineation (Morro Group, 2004); ¥ Irish Hills Plaza II Wetland Delineation Map (Morro Group, 2004); ¥ Hydrologic Monitoring Plan for Sustaining a Separated Wetland Near Calle Joaquin (Balance Hydrologics, 2005); ¥ 90-Day Report of Wet Season Fairy Shrimp Surveys, Calle Joaquin Site, San Luis Obispo (Thomas, 2005); ¥ Irish Hills Plaza Detention Basin Report (Wallace Group, 2006); ¥ Year 5 Wetland Monitoring Report for the Froom Ranch/Home Depot Site (Olberding Environmental, 2007); ¥ Los Osos Valley Road/U.S. 101 Interchange Improvements Project Biological Assessment for Central California Coast Steelhead (2008); ¥ Irish Hills Natural Area Conservation Plan Update (City of San Luis Obispo, 2011); KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 8 ¥ Madonna Enterprises Vachell Lane Property 2013 Wet Season Vernal Pool Branchiopod Survey 90-Day Report (Sage Institute, Inc., 2013); ¥ Madonna Enterprises Vachell Lane Property 2013 Dry Season Vernal Pool Branchiopod Survey 90-Day Report (Sage Institute, Inc., 2014); ¥ Chevron Tank Farm Remediation and Development Project Final Environmental Impact Report (Marine Research Specialists, 2013); and ¥ Froom Ranch Delineation of Waters of the United States and State of California (Wetland Delineation; KMA, 2015). Other reports from the project area including the VPFS survey findings (both wet season and dry season) for the Calle Joaquin Road Realignment project (conducted by Ms. Thomas), which included the project site, and the Vachell Lane Property (Sage II, 2013) were also reviewed. Conversations with other local branchiopod experts (pers. comm. Mitch Dallas and David Wolff) regarding their recent studies also occurred. Historical aerial photographs obtained from Google Earth were reviewed to further aid in the existing conditions characterization, and were compiled and included as an appendix to this report. The California Natural Diversity Database maintained by the California Department of Fish and Wildlife (CNDDB, 2017) was searched for listed branchiopod species that have been documented within the United States Geological Survey’s (USGS) 7.5-minute topographic quadrangle maps centered on and surrounding the site. This included the Morro Bay South, San Luis Obispo, Lopez Mountain, Port San Luis, Pismo Beach and Arroyo Grande Northeast quads. Given the project site’s proximity to the Pacific Ocean and geographic setting on the northern flank of the Irish Hills of the San Luis Range in close proximity to San Luis Obispo, the focus on these six quads was deemed a sufficient search area to identify listed branchiopod species occurring in the vicinity of the site for inclusion in the study. To support the Vernal Pool Habitat Assessment, the Natural Resources Conservation Service (NRCS) Web Soil Survey was reviewed to determine the soil mapping units present within the study area (U.S. Department of Agriculture 2017). The U. S. Fish and Wildlife Service’s online Wetland and Critical Habitat Mapper (http://www.fws.gov/wetlands/Data/Mapper.html; http://criticalhabitat.fws.gov/crithab/) were also reviewed to evaluate the extent of documented wetlands and designated critical habitat in the region. 3.2 Vernal Pool Habitat Field Assessment As part of field work for the 2015 Wetland Delineation and 2016 Biological Resources Inventory, KMA’s Principal Biologist Kevin Merk conducted monthly surveys starting in January 2015 through October 2015 to track rain storms and characterize the hydrology of onsite drainage features (i.e., Froom Creek, its tributary drainages and the Los Osos Valley Road Ditch), constructed detention basins and the Calle Joaquin road impoundment. Additional site visits were conducted by Mr. Merk and other KMA biologists during the 2016-17 rain season to further map and define the extent of regulatory agency jurisdiction over the drainages and wetland areas onsite. During the site visits, KMA biologists explored the site extensively on foot and by four-wheel drive vehicle. All areas of hydrologic significance, including Froom Creek, its tributary drainages and associated seeps/springs and the LOVR ditch were visited. Any areas with ponded water or topographic swales or seeps/springs, which appeared to have the potential to pond water or maintain prolonged soil saturation were mapped and assessed for the presence of the three federal wetland criteria (i.e., hydric soils, predominance of wetland vegetation, and wetland hydrology). Please KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 9 refer to the 2015 Wetland Delineation Report and the 2016 Biological Resources Inventory prepared by KMA for further discussion. The Wetland Delineation Overview Map is included in this report. For the vernal pool habitat assessment, two additional site visits were conducted in September 2017 by Mr. Merk and Ms. Thomas to identify and survey areas with ponded water or the potential to contain pond water on a seasonal basis. The surveys searched for potential seasonal ponding indicators such as subtle changes in topography, predominance of wetland vegetation, accumulated sediment, dried mud, cracked clay soils or surface saline deposits. All drainage features, swales, ditches, basins, and topographic depressions were examined to assess the potential of supporting ponding water (at least 3 cm) with little flowing water during the wet season for sufficient duration (estimated at a minimum of two weeks) to allow a fairy shrimp population to complete a reproductive cycle. Aerial photographs of the property, wetland delineation maps, and a Trimble GeoXH 6000 GPS unit were used to record the locations of areas considered potential habitat. Photographs were taken of these locations, and record made of the vegetation present. Plant species were recorded following the Jepson Manual, second addition (Baldwin et al., 2012). Robert Hoover’s The Vascular Plants of San Luis Obispo County, California (1970) and the California Consortium of Herbaria accessed online were also used to identify plants observed onsite. 3.3 Qualifications of Surveyors KMA biologists Kevin Merk and Julie Thomas conducted this vernal pool habitat assessment survey. Both Mr. Merk and Ms. Thomas are familiar with vernal pool habitat and associated vegetation in the San Luis Obispo County area. Mr. Merk has worked extensively throughout California in vernal pool regions conducting wetland delineations and surveying for listed branchiopods and amphibians such as the California tiger salamander (Ambystoma californiense). In addition, Ms. Thomas has over 15 years of experience conducting protocol surveys for vernal pool fairy shrimp and assessing potential habitat throughout Central California, including San Luis Obispo County, and holds a valid USFWS 10(a)(1)(A) recovery permit for listed branchiopods (#TE834492-5). 4.0 RESULTS 4.1 Vernal Pool Habitat Assessment VPFS have been recorded at two sites located within two miles of the proposed Froom Ranch project site: ¥ At the former Chevron Tank Farm on Tank Farm Road in San Luis Obispo, multiple surveys have identified VPFS populations in remnant tank rings, former earthen bermed oil reservoirs, drainage ditches with little to no flowing water and other altered landscape features and topographic depressions on the property (Marine Research Specialists, 2013). Linderiella occidentalis (California linderiella), a more common fairy shrimp, has also been recorded on this property, and in some instances co-occurs with VPFS. ¥ A population of VPFS was more recently recorded in a seasonal pond/swale feature on the east side of Vachell Lane between South Higuera Street and Buckley Road in the County of San Luis Obispo during wet season surveys in 2004-05, and again with dry season sampling in 2013. Linderiella occidentalis was also recorded in this location (SII; 2013, 2014). KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 10 The above VPFS sites and the Froom Ranch property are not connected via surface hydrology, but the proximity of these VPFS populations suggests the possibility that cysts could be transported to the Froom Ranch property via birds and other wildlife that could cross urban areas and Highway 101. However, even if viable VPFS cysts were introduced by migrating wildlife, a population could only be established on Froom Ranch if suitable habitat were present. On the Froom Ranch property, KMA identified three features with potential to pond water with a depth and duration sufficient to potentially support listed branchiopod species: two constructed earthen drainage basins that are part of the Irish Hills Plaza infrastructure (“north drainage basin” and “south drainage basin”), and a wetland area adjacent to the intersection of Calle Joaquin and Los Osos Valley Road (“Calle Joaquin wetland”). Please refer to Figures 4 and 5 for location information. Other wetland, creek and drainage features in the Froom Ranch survey area do not provide potential habitat for listed branchiopod species, either because they periodically experience scouring flows, do not exhibit the topography to pond water at the required depth and duration to support the species, or because they are perennially moist seeps. Both the north and south drainage basins, as well as the Calle Joaquin wetland, occur on the NRCS soil map unit Cropley clay, 0-2% slopes (Figure 6), described as follows: Cropley clay 0-2 % slopes. Cropley clay consists of a dark gray or black (10YR 4/1, 3/1, 2/1 moist) clay horizon about 36 inches thick, underlain by a light brown calcareous clay loam to 60 inches or more. Permeability of this soil is slow and the available water capacity is high. Cropley soils formed in alluvium developed from sedimentary rocks. An unnamed component of Cropley clay is listed as a hydric soil when present in drainageways. This inclusion is typically very dark gray throughout, with mottles present in the lower horizons. Mapped inclusions within this series include Diablo clay, Los Osos loam, and Salinas silty clay loam. (NRCS 2015) The Cropley clay soil as described has the characteristics that would enable it to provide a claypan substrate that could pond water on a seasonal basis. Discussion of the VPFS habitat potential of the north and south drainage basins and the Calle Joaquin wetland follows below. Also, please refer to the historic aerial photographs included as Appendix A and site photographs in Appendix B for further detail. 4.1.1 Calle Joaquin Wetland The southwest side of the intersection of Los Osos Valley Road and Calle Joaquin contains a wetland community associated with the LOVR roadside drainage ditch, which was likely created or enlarged by alteration of natural topography when the roads were constructed, resulting in increased impoundment of surface and subsurface flow. Under the proposed Froom Ranch plan, this wetland would be in the portion of the property to remain as protected open space. A number of biological and hydrologic studies have been completed at this location for prior projects, including the Calle Joaquin Road realignment, and the LOVR/Highway 101 interchange project. Focused protocol level surveys for VPFS for the Calle Joaquin Road realignment did not locate the species in the wetland area. The 2015 wetland delineation completed by KMA reported that this area exhibited a dense cover of perennial wetland plants trending toward coastal and valley freshwater marsh habitat, Los Osos Valley RoadCalle J o a q u i n Irish Hills PlazaDrainage 1 Drainage 2 Drainage 3 Froom Creek Figure 4a Figure 4b MountainbrookChurch Irish Hills Natural Reserve Study Area Boundary CDFW Jurisdiction (5.41 acres) USACE Wetlands (7.25 acres) USACE Other Waters (2.66 acres) John Madonna Construction, Inc.0 200 400 600 800100Feet Wetland Delineation Overview Source(s): RRM Design Froom Ranch Figure 41 in = 350 ft £¤101 L o s O s o s V a l l e y R o a d ²1 in = 800 ft 0 530 1,060265Feet Figure 5 Soil Map JM Development Group, Inc.

The vegetation in the Calle Joaquin wetland area was: “…dominated by clustered field sedge, and included distinct areas of silverweed (Potentilla anserina - OBL), brown-headed rush (Juncus phaeocephalus - FACW), round-leaf leather root (Hoita orbicularis - OBL), and rough sedge (Carex senta - OBL). Ponded areas containing California bulrush (Schoenoplectus californicus - OBL), were present along portions of the property edge along Calle Joaquin.” (KMA 2015) The September 2017 field visits conducted for this vernal pool habitat assessment recorded these same dominant vegetation species, and surface ponding of between four and 18 inches was present in the area dominated by California bulrush. The 2015 wetland delineation concluded that this non-riparian wet meadow area dominated by wetland vegetation would be classified as Palustrine Emergent Wetland per Cowardin, and met the federal wetland criteria and falls under regulatory jurisdiction of the U.S. Army Corps of Engineers (KMA 2015; Cowardin et al. 1979; USACE 2008). The dominance of perennial wetland vegetation, observed surface ponding into September, as well as review of historical aerial photographs obtained from Google Earth, suggests that the Calle Joaquin wetland site functions as a semi-perennial to perennial wetland. In addition, during the field visits, a crayfish carcass between the south basin and the Calle Joaquin wetland ponded area provided supporting evidence of the semi-perennial ponding regime (USFWS 2015). If fairy shrimp cysts were introduced into the Calle Joaquin wetland by migrating wildlife or birds, and the pool was inoculated during a period when the pond went intermittently dry, the fairy shrimp population, if established, would likely be eventually decimated by predator species during subsequent wetter years with longer periods of ponding. Although there are exceptions, generally fairy shrimp species such as VPFS are absent from habitats supporting the abundance of predators expected in more permanent waters such as dragonfly larvae, notonectids, dysticid beetles, fish, crayfish; this includes the later stages of temporary habitats when the abundance of predators is usually at a maximum (Keeley and Zedler, 1998; USFWS 2015). Prior fairy shrimp surveys at this site that produced negative results support the conclusion that the Calle Joaquin wetland does not provide suitable fairy shrimp habitat. The 2004-05 protocol fairy shrimp surveys (wet and dry season) conducted at the Calle Joaquin wetland area as part of the Calle Joaquin Realignment Project found no VPFS or other listed vernal pool branchiopod species present (Thomas 2005). Although the footprint of the Calle Joaquin wetland as sampled in 2004-05 was somewhat altered by the subsequent road realignment project, the area continues to function as a semi-perennial to perennial wetland. 4.1.2 Stormwater Detention Basins Construction of the Irish Hills Plaza included two large stormwater detention basins, immediately adjacent to each other and separated by an earthen berm. The basins were constructed between mid-2006 and mid-2007. A temporary basin was also constructed to handle construction runoff before the larger basins were fully operable. After completion of construction of the Home Depot and surrounding areas, surface runoff from the Irish Hills Plaza development is now directed into the larger drainage basins, and the temporary basin was filled in and recontoured, and no longer has the capacity to pond water. KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 14 The two currently active drainage basins, referred to here as “north basin” and “south basin” release overflow water to the LOVR Roadside Ditch via a storm drain outfall into a constructed swale. During large storm events, they are designed to discharge water into the wet meadow area along Calle Joaquin via a concrete spillway on the south side of the south drainage basin. Otherwise, water leaves the basins through evaporation and ground percolation. Google Earth historical aerial imagery indicates that these basins have been actively managed, with grading of the basins performed between April and August 2013, disturbing soil and removing vegetation (Appendix A: August 23, 2013). Under the proposed Froom Ranch development plan, these drainage basins would be removed, and runoff would be redirected into new constructed features including a larger basin proposed on the neighboring Mountainbrook Church property adjacent to Froom Creek. During the September 2017 habitat assessment field visits, the north basin featured shallow ponding (average 4-8 inches in depth) throughout much of the basin. Vegetation was dominated by obligate wetland plants such as cattail (Typha latifolia), spikerush (Eleocharis macrostachya) and small fruited bulrush (Scirpus microcarpus) along with brown-headed rush (Juncus phaeocephalus) and rabbitsfoot grass (Polypogon monspeliensis). The south basin was densely vegetated, but did not have ponded water or the predominance of obligate wetland plants, though signs of recent seasonal ponding were evident in the form of algal mats, cracked soil and surface salt deposits. Dominant vegetation included facultative wetland species such as creeping rye (Elymus triticoides), brown-headed rush, and reed fescue (Festuca arundinacea) with patches of cattails were present in several areas where saturation persists In the more barren patches exhibiting salt crust and/or algal mats from recent drying, prickly sow thistle (Sonchus asper; FAC) frequently occurred. Neither Congdon’s tarplant (Centromadia parryi ssp. congdonii) nor Hoover’s button celery (Eryngium aristulatum var. hooveri), which are both indicators of vernal pool or seasonal wetland habitat, were observed in either drainage basin. Historical aerial photos reviewed on Google Earth show that the north and south basins both dry out seasonally in most years. The high rainfall of 2016-17 may be responsible for the continued ponding seen in the north basin in early September 2017, as well as for ponding that appears to have lasted into the summer in the south basin, based on presence of algal mats and salt deposits. The wetland plant species currently dominating both basins suggest semi-perennial wetland hydrology, but aerial photos taken as recently as September 2016 show the vegetation in both basins as almost entirely brown, with no visible surface ponding. The pattern of seasonal drying shown in the historic aerial photos suggests that it is possible that the basins might have a hydrologic regime in many years that would provide suitable fairy shrimp habitat, even though the current year’s vegetation community is more typical of a semi-perennial wetland, which would be unsuitable habitat. The fact that the basins were constructed as recently as 2006-07, and then graded for maintenance in 2013, and are not hydrologically connected to existing fairy shrimp habitat, makes it unlikely that there has been time for fairy shrimp to be inoculated into the basins and to develop into a sustained population, even if a suitable hydrologic regime exists. Soil disturbance such as grading can easily bury or remove fairy shrimp cysts, and is generally considered incompatible with presence of a persistent fairy shrimp population. Based on the recent construction and management history of these two drainage basins, and the lack of direct connectivity with other fairy shrimp habitat, it is very unlikely that the basins support a population of listed branchiopods. KMA Froom Ranch Specific Plan Project Vernal Pool Habitat Assessment JM Development Group, Inc. 15 4.1.3 Critical Habitat Designation The U.S. Fish and Wildlife Service designated critical habitat for VPFS in the region (Units 29C and 30, designated in 2006), but outside the five mile buffer around the study area. The proposed project area is not situated within a critical habitat unit, and no critical habitat attributes were observed within the study area. 5.0 CONCLUSION Based on field surveys and review of relevant background documents of the Froom Ranch site, three features were initially identified as having characteristics of a seasonal ponding and drying regime with the potential to support listed branchiopods: the north and south drainage basins, and the Calle Joaquin wetland. The north and south drainage basins were dominated by wetland vegetation at the time of field surveys in September 2017. Much of the north basin was still ponded with water, averaging four (4) to eight (8) inches in depth. The south basin was not ponded, but showed signs of recent drying in the form of salt deposits on the substrate surface, and much of the basin was dominated by wetland vegetation. These factors could suggest that the drainage basins have a semi-permanent wetland hydrologic regime; however, historic aerial photos show that, in most years since the basins were constructed, the basin vegetation was brown by end of summer, and no ponding is evident. It’s likely that the extent of wetland vegetation and ponding observed in September 2017 is an anomaly resulting from the exceptionally wet 2016-17 rain season, and that in most years the basins do dry out for a number of months, and in general have a seasonal ponding regime. However, both of the drainage basins were constructed within the past 11 years, and since they are not hydrologically connected to known fairy shrimp habitat, there has been limited time and opportunity for inoculation of the basins through wildlife transfer of cysts. In addition, the basins are actively managed to maintain holding capacity and, based on aerial photos, were subject to maintenance activities including grading in 2013. Inoculation and population establishment of fairy shrimp would therefore have had to occur after the 2013 grading. Given the lack of immediate proximity to existing fairy shrimp habitat and the ongoing maintenance activities in the drainage basins, it is considered very unlikely that the drainage basins provide habitat for listed species of branchiopods such as VPFS. The Calle Joaquin wetland had been sampled for listed branchiopods during 2004-05 and no fairy shrimp species were found to occur there. Historic aerial photos suggest that the Calle Joaquin wetland area remains moist or ponded throughout most years. KMA field surveys for this assessment found wetland vegetation dominant in the area subject to ponding, as well as hydric soils and evidence of presence of aquatic predator species generally considered incompatible with listed branchiopod populations. Based on these factors, the Calle Joaquin wetland is not considered potential habitat for listed species of branchiopods. 6.0 REFERENCES Baldwin, B. G., D. H. Goldman, D. J. Keil, R. Patterson, T. J.

APPENDIX G Response to EIR Consultant Supplement Information Request KMA KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 1 Appendix G – Response to EIR Consultant Supplemental Information Request 1. Amend Biological Resources Inventory report to provide a better description of wetland features in the 3.2 acre Irish Hills Plaza Basin. Response: Biological Resources Inventory Report was revised. Refer to page 20. Also please refer to the Vernal Pool Habitat Assessment and Site Assessment for the California Red-Legged Frog prepared for the project by KMA in 2017. 2. Provide any correspondence with the U.S. Army Corps of Engineers (Corps) regarding “spigot wetlands”. Response: The Corps reviewed the Wetland Delineation Report prepared by KMA in 2015 and concurred with the delineation maps that do not identify the constructed basins being subject to their Clean Water Act Section 404 jurisdiction. No mention of the term “spigot wetlands” was included in their determination letter dated September 24, 2015 sent to Mr. John Madonna, but the Clean Water Rule (2015) states that “artificial lakes or ponds created by excavating and/or diking dry land and used exclusively for such purposes as stock watering, irrigation, settling basins or rice growing” are not subject to Clean Water Act regulation. Further clarification is provided in the Clean Water Rule as follows: “Artificially irrigated areas that would revert to upland should irrigation cease” (i.e., a spigot wetland, which refers to a wetland formed artificially) and “water filled depressions created as a result of construction activity” are also not subject to the regulatory authority of the Corps pursuant to Section 404 of the Clean Water Act. If the spigot was turned off, the wetland feature would revert to upland. 3. Provide a complete background/history of the Home Depot temporary settling basin (approximately one acre basin that was removed from the site). Response: It is KMA’s understanding that the Home Depot basin was constructed to handle stormwater for the project to the north. It acted as a temporary settling basin during construction of the neighboring Irish Hills Plaza and Home Depot project. Once construction of the Irish Hills Plaza Basin was complete in 2006, the Home Depot Basin was no longer needed since the project’s stormwater system was tied into the larger Irish Hills Plaza Basin constructed further south. The Home Depot Basin and Irish Hills Plaza Basin were strategically sited in upland areas to avoid any potential wetland features. The Home Depot Basin had an outlet swale shown on the project plans that extended to Los Osos Valley Road, which was through a mapped wetland. The outlet swale was apparently not included in the Department of the Army permit acquired for the project, and once it was constructed, the Corps required the swale to be removed. To allow surface drainage from the basin to flow towards Los Osos Valley Road consistent with historic drainage patterns, notches were cut in the eastern berm to allow water to leave the basin after sediment and stormwater contaminants had settled. Other un-permitted impacts to Corps jurisdictional wetlands also occurred during construction of the project, and the Corps suspended the Nationwide Permit issued for the project. In order to resolve the violations, the applicant combined the two mitigation locations into a single site, the Boysen Ranch, and a revised mitigation plan was prepared by Olberding in 2002. The applicant was required to restore the two areas on the current KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 2 Froom Ranch site where un-permitted impacts occurred, and this included a 0.26-acre stockpile location and 0.36-acre ditch/swale excavated from the temporary basin to Los Osos Valley Road. It also included re-contouring an earthen berm constructed during initial grading on the Boysen Ranch that apparently encroached on existing wetlands to be preserved. Onsite wetland mitigation was originally proposed as part of the project and included constructed swales on the western and southern boundaries of the site. In addition, mitigation measure Bio-2 in the Eagle Hardware EIR stated that the proposed Home Depot Basin should be reconfigured to provide some wetland mitigation for project related impacts. The record is unclear, but it appears that due to the series of violations associated with the project’s Department of the Army permit acquired for wetland impacts, the Corps and developer went to court and a consent decree was issued requiring the completion of additional mitigation. The wetland mitigation requirements were increased to 14.9 acres to compensate for the originally permitted impacts to 2.93 acres of wetland and the construction violations to an additional 2.81 acres. An agreement was made between the Corps and permittee to complete all wetland mitigation requirements offsite at the Boysen Ranch. It is uncertain if the City of San Luis Obispo was involved at that time, but ultimately accepted a conservation easement over the Boysen Ranch wetland mitigation area and annexed the project. The County of San Luis Obispo, which was the lead agency for the Eagle Hardware project, was contacted and no records such as a final Mitigation Monitoring and Reporting Program were located to confirm all wetland mitigation associated with mitigation measure Bio-2 was completed offsite. None the less, the Corps reviewed five years of annual monitoring reports for the wetland mitigation efforts at Boysen Ranch and confirmed in a February 19, 2015 letter to Mr. Clint Pearce of Madonna Construction Company that all mitigation requirements (i.e., final success criteria) associated with the project were met, which facilitated termination of the consent decree. 4. Will construction of the proposed stormwater basin on the Mountainbrook Church property impact Froom Creek between the Specific Plan boundary and Calle Joaquin/Highway 101? Response: Based on the preliminary plans prepared to date and the concept that the proposed basin will handle high flows within Froom Creek and reduce flooding potential onsite, approximately 50 to 100 feet of impact is estimated to occur to the southern creek bank of Froom Creek just south of the Specific Plan boundary. The bank on the north side pf the creek where the hotel is located would not be affected. Within this 50 to 100 foot zone, the upper bank would be affected by grading and earth work to create an overflow point to allow high flows within the creek to enter the basin (the inflow feature) and be retained until the flows subsided. A spillway (the outflow feature) would also be constructed within this area to allow flows to potentially re-enter the creek during the larger storm events. The goal will be to site the disturbance area in a more open area outside any riparian scrub habitat. Still, the creek bank will be graded and arroyo willows could be removed and trimmed. Most likely, the upper creek bank would be recontoured to create the inflow/outflow features, but the bed of the channel may also require alteration and possibly armoring with rock slope protection. Should earthen berms be required, they would be strategically set back from the top of bank and outer limits of riparian scrub habitat to avoid and minimize impacts to jurisdictional areas . Ultimately all project related activities that KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 3 affect the Froom Creek’s bed or banks would be under the review and approval (through permit issuance) of the California Department of Fish and Wildlife, Regional Water Quality Control Board, and U.S. Army Corps of Engineers. The U.S. Fish and Wildlife and NOAA Marine Fisheries Service are also expected to be involved through the interagency consultation process defined under Section 7 of the federal Endangered Species Act. 5. Amend the Biological Resources Inventory Report to provide further text narrative detailing the current regulatory status of wetlands including replacement at Boysen Ranch. Response: The Biological Resources Inventory was prepared to document existing conditions of the site, and not to provide impact analysis of the proposed Specific Plan project or the history of the neighboring project to the north. The current regulatory status of wetlands onsite are documented in the Wetland Delineation Report prepared by KMA in 2015 and subsequent Preliminary Jurisdictional Determination completed by the Corps (2015 letter from the Corps to Mr. John Madonna). The consent decree was a court order placed on the Home Depot project for impacts to wetlands that exceeded those allowed under the project’s Department of the Army permit. While it appears that there was intent by the lead agency and applicant to provide some wetland mitigation onsite (Eagle Hardware mitigation measure Bio-2), the increase in mitigation requirements rendered by the Corps steered all wetland mitigation to an offsite location at the Boysen Ranch. The Corps evaluated five years of monitoring reports and conducted a site visit to confirm the wetland mitigation effort met the final success criteria identified in the 2002 Wetland Mitigation Plan prepared by Olberding. A letter from the Corps to Mr. Clint Pearce of Madonna Construction (2015) confirmed all mitigation was complete, and subsequently the consent decree was terminated. No wetland mitigation for the Home Depot project (formerly Eagle Hardware) beyond the construction of the west and south swale features occurred on the Froom Ranch property. The updated wetland delineation (KMA 2015) and the final Olberding monitoring efforts used methods described in the Wetland Delineation Manual (and Arid West Supplement) to confirm the extent of Corps Section 404 jurisdictional wetlands on the Froom Ranch and Boysen Ranch and offsite mitigation area. 6. Connectivity to wetlands. As stated in the BRI and Wetland Delineation Report and later confirmed in the Cleath- Harris Geologists Groundwater Assessment report, a combination of surface and subsurface hydrology elements support wetlands along Los Osos Valley Road and Calle Joaquin. Groundwater is shallow in this area from the historic confluence of Prefumo Creek and Froom Creek with San Luis Obispo Creek. Road construction and other development in the area may have also further impounded and influenced the hydrology of the area that supports the wetland features on both sides of Calle Joaquin. The Cleath groundwater assessment anticipates increased water available in the Calle Joaquin wetland area once the project is constructed and Froom Creek re-aligned to its historic location. The goal of the Froom Creek restoration concept is to increase the extent of wetland and riparian habitat and create more prolonged seasonal pools in the channel KMA Froom Ranch Project Biological Resources Inventory Revised November 2018 JM Development Group, Inc. 4 capable of providing a stepping stone for steelhead between San Luis Obispo Creek and the upstream reaches of Froom Creek. 7. Value of proposed stormwater basin as a wetland feature. Response: The proposed offsite stormwater basin will replace the Irish Hills Plaza Basin, and will not be used for wetland mitigation due to the need to conduct maintenance similar to the existing basin complex. Maintenance of onsite basins includes annual clearing of vegetation and accumulated sediment and debris. Once constructed, the new basin would be hydroseeded with an assemblage of native species tolerant of seasonal inundation to provide vegetation cover of the basin floor and the earthen berm. Given the presence of seasonal surface water during the winter rain season, some wetland vegetation, such as airborne seed from cattails, is expected to colonize the floor of the basin, similar to the seasonal variation in vegetation in the current Irish Hills Plaza Basin.

LIST OF ATTACHMENTS 0 SUMMARY The following document was prepared to present the Year 5 monitoring results of the Boysen Ranch mitigation property and the restoration efforts at the Home Depot on Los Osos Valley Road, located in San Luis Obispo, California (please see Attachment No. 1, Figures 1-3). This report has been prepared as specified in the “Wetland Restoration and Mitigation Plan Relating to the Froom Ranch/Home Depot Project” dated June 10, 2002. The Year 5 monitoring report is the last of five reports that shall be used to determine the overall success of the mitigation site and restoration efforts. The fill of 2.93 acres of jurisdictional seasonal wetland habitat was originally permitted by the U.S. Army Corps of Engineer (Corps) to facilitate construction of the Home Depot store located in San Luis Obispo on Los Osos Valley Road. Original mitigation proposed to offset jurisdictional impacts included the creation of 4.7 acres of seasonal wetland habitat. Alleged violations at the Home Depot construction site included 2.81 acres of fill. Mitigation proposed to replace wetland values for the violation was 10.2 acres of seasonal wetland. Also the mitigation included the restoration of 0.9 acres of swale and drainage ditch in the Home Depot construction area. The original mitigation and the mitigation for the violation combined for a total of 14.9 acres of creation. This final acreage was proposed to mitigate all impacts at the Home Depot store site at Froom Ranch with the exception of the restoration work on the swale and drainage ditch. In addition, the impacts associated with the relocation of the roadside ditch parallel to Los Osos Valley Road consisted of 1.37 acres. This impact was mitigated through the construction of 1.51 acres of wetland habitat at the Boysen Ranch mitigation property and the creation of 0.55 acres adjacent to Los Osos Valley Road. Total mitigation for Los Osos Valley road was 2.06 acres. Construction of wetland habitat at the Boysen Ranch mitigation area was achieved in the fall of 2002 with initial monitoring of the site being performed in early 2003. Five wetland polygons were constructed and named Area A, Area B, Area C, Area D, and Area E. A total of 16.96 acres of wetland habitat was created in the five areas for the Froom Ranch/Home Depot Project, the alleged violation, and the Los Osos Valley Road widening. These wetlands were positioned adjacent to an unnamed seasonal creek channel and consisted of shallow basins. Hydrology to the mitigation site was designed to originate from rainfall, from adjacent upland runoff and from flooding when the creek channel is overtopped. The Boysen Ranch mitigation area and the relocated LOVR drainage ditch continue to meet the established success criteria as of the site visit performed in May 2007. The natural wetland hydrology of both sites provides appropriate conditions for the establishment of hydrophytic vegetation. Soils at the mitigation sites meet the criterion to be determined wetland. Cover and wetland species composition are appropriate for the Boysen Ranch and LOVR site and the mitigation monitoring results indicate successful establishment of wetland conditions. 1 1.0 PROJECT DESCRIPTION 1.1 Background 1.1.1 Home Depot/Froom Ranch This report summarizes the Year 5 monitoring results prepared for Froom Ranch/Home Depot located at the Boysen Ranch, San Luis Obispo, California. This document provides the objectives, methods, results, conclusions and recommendations for the success of onsite wetland mitigation required as a condition of U.S. Army Corps of Engineers (Corps) Permit No. 985007300-TW and Regional Water Quality Control Board (Regional Board) Water Quality Certification Resolution No. 98-095. Corps authorization under Nationwide Permit (NWP) No. 26 Headwaters and Isolated Waters was verified on February 11, 1999, allowing the construction of the Home Depot store site within the Froom Ranch area along Los Osos Valley Road. Specifically, NWP 26 authorized impacts to approximately 2.93 acres of jurisdictional wetlands. Of the 2.93 acres approximately 2.88 acres were to be permanent impacts from fill activities, with the remaining 0.04 acres being temporary impacts. On November 17, 2000, Madonna Construction Company began grading and fill work for the development project. Work at the Boysen Ranch mitigation site was also performed during this time frame, prior to December 20, 2000. In a letter dated March 14, 2001, the Corps suspended NWP 26 verification for the Project because of alleged violations of the permit's terms and conditions. The alleged violations where associated with grading, excavation and placement of fill into non-permitted jurisdictional wetlands associated with development activities. The Corps claims that during project construction an additional 2.81 acres of jurisdictional seasonal wetland habitat was allegedly filled on Froom Ranch and the site of the Home Depot Project. In order to resolve the alleged violations, Madonna proposed the creation of 10.2 acres of new jurisdictional seasonal wetland habitat on the Boysen Ranch site in addition to the 4.7 acres of mitigation habitat originally associated with the Home Depot Project. The two mitigation locations adjoin each other. Combining the two mitigation sites required that the originally prepared mitigation plan be incorporated into one comprehensive document for ease in implementation and monitoring. 1.1.2 Los Osos Valley Road Improvement In addition to the Home Depot construction related mitigation, the mitigation and monitoring activities required for the Los Osos Valley Road Improvement Project (LOVR Project), are included in this document. Madonna Construction Company was authorized by a Department of the Army Section 404 Permit, to permanently fill approximately 0.73 acres and temporarily impact 0.64 acres of degraded seasonal wetland and constructed roadside ditch (drainage ditch) 2 habitat adjacent to the existing roadway. The LOVR Project included the placement of approximately 5,500 cubic yards of fill material (imported soils) into jurisdictional wetlands facilitating the widening of a 2,800-foot segment of Los Osos Valley Road from Garcia Drive to Calle Joaquin, which is located several hundred feet northwest of Highway 101. Impacts to jurisdictional wetlands were replaced at a 1.5:1 ratio by a combination of on-site and offsite mitigation. Approximately 1.37 acres of low quality seasonal wetland and constructed drainage ditch habitat on-site was replaced with 1.51 acres of moderate to high quality seasonal wetlands off-site. This mitigation involved the off-site creation of 1.51 acres of new seasonal wetlands on the Boysen Ranch property. On-site mitigation consisted of the relocation of a drainage ditch at the base of the newly widened LOVR and the construction of a 425-foot bypass swale located several feet off the road in the adjacent field for a total of 0.55 acres. A portion of the ditch along LOVR was vegetated with riparian species. Total mitigation for the LOVR impacts amounts to 2.06 acres. 1.2 Restoration Activities In addition to creating mitigation wetland habitat at Boysen Ranch, the applicant also restored several sites where the alleged violations took place. Areas restored at Froom Ranch included the 0.26 acre stock pile location; and the 0.36 acre excavated ditch leading from the constructed detention basin. In addition, the entire southwestern channel beginning behind (south of) the new building and wrapping around the west side of the project on Froom Ranch were filled. All surface water was directed to the remaining southwestern channel, which leads to the detention basin. The area to be restored at Boysen Ranch included the 0.34 acre berm. Original topography has been restored to pre-impact conditions through minor grading activities. These areas are being allowed to restore naturally. The berm surrounding the constructed detention basin at Boysen Ranch has been redesigned to include several notches to allow higher flows to sheet flow out of the basin rather than discharge through a single channel (see Attachment 1, Figure 8). A total of 0.96 acres was restored at the Home Depot/Froom Ranch area.

Approximately 16.96 acres of created wetland habitat was created on the Boysen Ranch immediately adjacent to an existing drainage channel located west of Foothill Road, north of Los Osos Valley Road, and south of O’Conner Way. Attachment 1, Figures 6 and 7, depict the location where seasonal wetland habitat was created. The site is reached by driving west on Los Osos Valley Road through western San Luis Obispo. Drive through town and at Foothill Road turn north. The mitigation area lies to the west of the road. Restoration areas in the Home Depot/Froom Ranch area occur to the south of the Home Depot development area and are depicted in Attachment 1. The areas restored are located on the north side of Los Osos Valley Road north of Highway 101. Along Los Osos Valley Road 0.55 acres of channel habitat were relocated, and the 0.96 acres of restoration at the alleged violation sites were corrected for a total of 1.51 acres at the Froom Ranch/LOVR site. 1.4 Objectives of Monitoring Mitigation monitoring at the Boysen Ranch creation site, Froom Ranch restoration site, and LOVR relocation site, calls for the evaluation of performance criteria (percent cover and site 4 maintenance) and trend characteristics (plant vigor/health, and natural reproduction/recruitment) for the mitigation site. Evaluation of these criteria will allow a determination of the need for erosion control, supplemental reseeding, weed control, and potential human disturbance. Also, the evaluation will determine the success or need for improvement of the mitigation effort. Table 3 below provides the initial target functions for the mitigation site and indicates the status of each function as of May 2007. Table 3 Boysen Ranch, Froom Ranch and LOVR Mitigation Monitoring Objectives Mitigation Site Target Functions Status An overall ratio of 2.5 acres of wetland will be created for each acre of wetland eliminated at Froom Ranch. For the LOVR project an overall ratio of 1.5:1 acres of wetland were created for each acre impacted. Table 1 provides a summary of the wetland impacts, by type, which would result from the proposal and the corresponding wetlands to be created. Impacted wetlands amounted to 7.11 acres. A total of 16.96 acres of wetlands were created in the winter of 2002. Year 5 monitoring verified the attainment of this acreage. Restoration amounted to 0.96 acres at Froom Ranch. Total wetland creation and restoration amounted to 17.92 acres. To assist in obtaining successful mitigation the project will also include the following: 1. No construction would occur in areas under Corps jurisdiction outside the permitted project footprint; No violation May 2007 2. Unless authorized by the Corps, no work would be conducted in or around the created wetland areas that may modify the hydrologic regime of the created habitats once established; No violation May 2007 3. No livestock grazing or plowing will be allowed; No violation May 2007 4. Off-road vehicle use would be restricted; No violation May 2007 5. No work would be conducted in or around the restored wetlands area that may modify the hydrologic regime of the wetlands once established. No violation May 2007 6. No off road vehicle use will be allowed within the wetland mitigation area; No violation May 2007 Table 4 Quantitative Vegetative Success Criteria 1. The site shall meet the 3 parameter wetland criteria as defined by the 1987 Wetland Delineation Manual for 17.92 acres of created and restored wetlands; 2. The wetland mitigation site shall have the same dominant wetland plants as the wetland reference site (80% similarity); 5 3. Plant diversity at the wetland mitigation site shall be a minimum of 50% of that found at the reference wetlands; 4. Non-native plant species identified by the Corps and the applicant as "nuisance species" shall not be greater than 5% of the total vegetation cover (cumulative for all species of nuisance plants) within the wetland mitigation area; and 5. The wetland mitigation area shall demonstrate natural hydrology. This shall be indicted by the lack of artificial irrigation for at least two years (with no loss of vegetation) and/or determination of direct surface flow into the wetland site from the two streams. 6. A final, recorded conservation easement shall be provided to the Corps for the 16.96 acre wetland mitigation area. 2.0 METHODOLOGY The mmitigation monitoring survey of the Froom and Boysen Ranch sites was conducted on May 9, 2007 by Olberding Environmental. Field surveys consisted of monitoring 14 pre- established transect lines bisecting the constructed habitat types. At Boysen Ranch 11 transects were located to represent the different areas within the mitigation site. Each transect line contained two to three data points. At Froom Ranch, one transect was established across the area which was restored, and two transects were established along the relocated ditch on LOVR. Conditions along each transect line are documented in photographs taken during the Year 5 monitoring period. These photographs have been included in this report (Attachment No. 2). During the May survey, wetland delineation data forms were completed for each data point location in accordance with U.S. Army Corps of Engineers wetland delineation criteria identified in the 1987 "Corps Wetlands Delineation Manual" (1987 Manual) 1. During Year 5, a total of 29 data points were evaluated. Data points were investigated in upland (A) and wetland (B) positions to establish a wetland/upland boundary and compare the vegetation, hydrology, and soils between the two locations. Information for vegetation, hydrology, and soils are provided on the data sheets located in Attachment No. 3. All collected information will be compared with that obtained during the Year 4 (2006) monitoring season. 3.0 RESULTS 3.1 Performance Criteria 3.1.1 Percent Cover An average cover of 67 percent was recorded for transects 1 through 11 in Boysen Ranch. The total percent cover between transects ranged from 0 to 100, with wide variation in between. Wetland cells A and C exhibited vegetation cover that exceeded 100 percent due to the layering of vegetation. Wetland cells B and D/E exhibited bare ground in many locations and supported a 1Environmental Laboratory. 1987. "Corps of Engineers Wetlands Delineation Manual."

A goal of 40 percent cover was established for the Year 5 monitoring event, and the average vegetation cover across the site exceeds this number. The upland areas within Boysen Ranch exhibited 100 percent cover composed of a mixture of annual and perennial grass species.

The LOVR relocated ditch had 100 percent vegetative cover on the banks and minimal cover on the channel bottom due to continuous water flows. The conveyance properties of the ditch may not allow for the growth of vegetation in the channel bottom but the 7 banks support wetland vegetation in excess of the target goals. Cattails were observed to have formed a small cluster upstream from the data points and may establish in the channel as flows slow. 3.1.2 Site Maintenance The mitigation sites were undisturbed during the May, Year 5 monitoring event. No additional maintenance was necessary for the 2007 season. 3.2 Trend Characteristics 3.2.1 Plant Vigor and Health The plants within the Boysen Ranch mitigation area exhibited a high vigor and health rating. All vegetation was robust, exhibited excellent color, and had abundant seed production. The salt grass, rabbit’s foot grass, and meadow barley were especially prolific within and outside of the created wetland cells, especially between Cells A and C and on the south side of Cell B. Wetland conditions have formed outside of the original outline of the basins and the vegetation across the entire mitigation area is thriving. At the restored swale, the plants exhibited medium to high health and cover was complete across the shallow depression. Vegetation at the relocated LOVR ditch exhibited medium to high vigor and health. There were tall recruits with many flowers and seeds which reflects the overall high rating. 3.2.2 Natural Reproduction/Recruitment At the Boysen Ranch area, the percent cover of vegetation remains nearly the same as observed in Year 4 and reflects the stabilization of vegetation across the site. Seed distribution sources that have populated the site include flooding, bird transport, and wind. The wetland vegetation within constructed cells B and D/E continues to spread, although incrementally. In the northern area of the mitigation site the salt grass continues to spread and thicken forming spongy mats where the vegetation depth is six to ten inches. Other species continue to increase in number and coverage including Parry’s tarpant, ammannia, and water plantain. Overall, the natural reproduction and recruitment on the site is excellent for the Year 5 monitoring event. The abundant vegetation exhibited in 2007 is attributed to the consistent rainfall in the region which inundates the mitigation site long into the growing season. For the restored swale area, there was 100 percent cover and recruitment was excellent. However, approximately half of the vegetation consists of wetland species, while the other species present are typically found in uplands. The relocated LOVR ditch exhibited abundant vegetation recruitment and the slopes to the channel are populated with many species such that the cover is 100 percent. The bottom of the 8 channel remains unvegetated and will likely become more populated over time. The flowing nature of the channel will limit vegetation growth to some extent in this region. During the heavy rainfall the high velocity of runoff in the drainage ditch results in scouring which removes soil and sediments from the channel. 3.3 Photo-documentation Please refer to Attachment No. 2 for photographs of the mitigation site. Photographs were taken on May 9, 2007 along several of the transect lines and at various locations around the mitigation site corresponding to areas designations. 3.4 Summary of Army Corps of Engineers Data Sheets Twenty nine data points were evaluated on 14 transects for vegetation, hydrology and soils in accordance with U.S. Army Corps of Engineers criteria for determining wetlands. For each transect there is one upland data point for a total of 14 upland positions in the mitigation area. There are a total of 12 wetland data points in the Boysen Ranch mitigation area and three wetland data points at the Froom Ranch/LOVR monitoring area. Attachment No. 3 includes the data forms prepared for the routine wetland determination surveys. 4.0 CONCLUSIONS 4.1 Evaluation of Quantitative Success Criteria - Year 5 Success Criteria 1. The site shall meet the 3 parameter wetland criteria as defined by the 1987 Wetland Delineation Manual for 14.9 acres of created/restored wetlands. The created wetlands at the Boysen Ranch meet the three Corps parameters for wetlands. Vegetative cover was lacking in those areas that were deeply inundated, but the majority of the site exhibited the germination and robust growth of wetland plant species. Wetland cells A and C exhibit a dense cover of wetland plant species. The wetland cells B and D/E are inundated for a very long duration that extends well into the growing season and typically retain water though late April and into May. The vegetation coverage within the deeply inundated basins reflects the long inundation period as swamp timothy, Parry’s tarweed, water plantain, and spike rush were the more commonly observed species. Other plants observed included alkali bulrush and cattails although these plants form only small colonies around the edges of the basins. Wetland soils were found at all locations as dark chromas and gleying was observed. Hydrology parameters were met at all data point locations as numerous primary and secondary indicators were observed. In summary, overwhelming evidence of the three Corps parameters for delineating wetlands was observed at the Boysen Ranch mitigation site. The restored swale and relocated Los Osos Valley Road ditch met the three Corp parameters for determining wetlands. The vegetation on the ditch banks is composed of hydrophytes which occur where saturation and ponding occurs for an extended period of time. Signs of active 9 hydrology were noted such as water lines on opposing banks, water marks on the plants, thick algal matting, and erosion in the channel. Soils also met Corp hydrology criteria with dark chromas corresponding to the presence of wetland vegetation and the observation of current hydology.

Success Criteria 2. The wetland mitigation site shall have the same dominant wetland plants as the wetland reference site (80% similarity). The wetland vegetation at the Boysen Ranch matches the wetland vegetation found at the reference site. The dominant wetland plants in the reference site consist of salt grass, brass buttons, and bird’s foot treefoil. These species are dominant at the mitigation site such that the 80 percent similarity criterion is satisfied. In 2007, the dominant wetland plants at Boysen Ranch consisted of rabbit’s foot grass, salt grass, and spike rush while bird’s foot trefoil, brass buttons, Mediterranean barley, and meadow barley were all associate species. During 2007, only salt grass was ranked in the top for total cover. The peak observation period for brass buttons, an annual species, occurs earlier in the year and the lower percent cover reflects the later time of year in which monitoring was conducted. It appears that bird’s foot trefoil has decreased in comparison to Year 4 monitoring likely due to out competition by saltgrass. The vegetation within the mitigation site is appropriate for the hydrology conditions and micro topography. The vegetation trends within the mitigation site will vary depending upon total water for each year. Water year conditions during 2006/2007 resulted in a shift in the most dominant plant within the wetland cells. There was a decrease in brass buttons and bird’s- foot trefoil and an increase in rabbit’s foot grass, salt grass, and spikerush. The rhizomatous perennial salt grass is establishing throughout many areas through the ongoing spread of underground runners. Fluctuations in vegetation cover from year to year will likely occur during every monitoring event with total percentage of cover varying, but the core species remaining the same. The restored swale (stock pile site) exhibited vegetation that was inconsistent with the reference site. The swale lacked wetland plants and was dominated by upland grasses. The vegetation at the swale prior to the placement of the stock pile was composed of curly dock, fiddle dock, prickly ox tongue, and rabbit’s foot grass. The restored swale supports Italian rye grass, soft chess, rip gut brome, and other annual grasses typically found in upland positions. The relocated ditch along LOVR exhibited vegetation similar to the reference site. The pre- existing wetland vegetation along the ditch consisted of cattails (Typha latifolia), iris-leaved juncus (Juncus xiphioides), curly dock, and arroyo willow (Salix lasiolepis). The banks and channel edges of the created ditch support curly dock, prickly ox tongue, and arroyo willow. Associate species consist of sow thistle, Italian rye grass, iris leaved juncus, and bird’s foot 11 treefoil. Cattails have not established in the section of the ditch that is monitored, but have established upstream from the monitoring location. The wetland mitigation site currently has the same dominant wetland plants as the wetland reference site. Success Criteria 3. Plant diversity at the wetland mitigation site shall be a minimum of 50% of that found at the reference wetlands. The composition of plant species found at the Boysen Ranch mitigation area includes all three of those which were found at the reference site. All the reference species were found within the basins and are continuing to spread in abundance. The Boysen Ranch site contains three of the three reference species, more than 50 percent of the plants found at the reference site, and meets the success criteria 3. The restored swale and relocated LOVR ditch contains three of the four plants found at the reference site and meets the plant diversity criteria with over 50 percent of the reference plant species. Success Criteria 4. Non-native plant species identified by the Corps and the applicant as "nuisance species" shall not be greater than 5% of the total vegetation cover (cumulative for all species of nuisance plants) within the wetland mitigation area. Nuisance plant species were not identified at the wetland mitigation sites. The success criterion 4 was met at Boysen Ranch, the restored swale, and the relocated LOVR ditch. Success Criteria 5. The wetland mitigation area shall demonstrate natural hydrology. This shall be indicted by the lack of artificial irrigation for at least two years (with no loss of vegetation) and/or determination of direct surface flow into the wetland site from the two streams. The Boysen Ranch wetland area demonstrated natural hydrology as the cells within each mitigation area were inundated with water during all or a portion of the winter. Water filled the basins by rainfall, onsite runoff, and from the drainage channel overtopping the banks. The wetland areas demonstrated evidence of natural hydrology as Areas A, B, C, D/E were under water for a long portion of the winter and early spring. Other hydrology indicators in the Boysen Ranch area included drift lines, sediment deposits, algal matting and water marks. Water was also documented to sheet flow into the basin from the south and north over the adjacent grassland vegetation. The entire Boysen Ranch site meets the Corps hydrology criteria based on the observed inundation at the wetland areas, and the presence of four primary indicators. The restored swale and constructed ditch along LOVR was observed to function as designed and exhibited water flows and hydrology consistent with the target goals. Water lines were observed on opposing banks. Algae and drift lines were documented at high positions along opposing banks in 2007. The natural hydrology criteria were met at the swale and LOVR ditch site. 12 Success Criteria 6. A final, recorded conservation easement shall be provided to the Corps for the 14.9 acre wetland mitigation area. The Corps of Engineers is currently in the process of obtaining a qualified third party to hold the easement. 5.0 RECOMENDATIONS The Boysen Ranch site, restored swale and LOVR ditch meet the requirements for mitigation success and no recommendations are proposed at this time. A conservation Easement will need to be recorded over the mitigation site.
