AMENDMENT#2 TO ENVIRONMENTAL SERVICES CONTRACT
CAO RECOMMENDATION
Approve and execute Amendment No. 2 to the Agreement to Furnish Environmental Services for
the Mid-Higuera Widening Project, Specification No. 90073B; in the amount of: $24,802 with
Morro Group, Inc.
DISCUSSION
The Mid Higuera Widening project involves the widening of Higuera Street from Marsh Street to
High Street. Cal Trans is the agency in charge of processing the National Environmental Policy
Act (NEPA) approval of this project, and in.2003, requested several technical reports necessary
to process this environmental clearance. The City then contracted with Morro Group, Inc., a
local environmental consultant, to complete these technical reports. The current agreement with
Morro Group consists of the original contract awarded by Council on November 5; 2003, and a
contract amendment which was approved by the CAO on March 3i;2004. All of the technical
reports originally requested have now been completed and submitted to Cal Trans for approval..
One of the technical reports is an Archaeological Survey Report. This report includes
preliminary "surveying of the site and has concluded that there is a possible presence of
archaeological artifacts or other similar items located within the area of potential disturbance for
the street widening. Based on the conclusions of this report, Cal Trans is requiring that.a follow
up study, known as an Extended Phase I Archaeological Survey, be performed. This Extended
Phase I Archaeological Survey was not included in the original scope of work contracted to
Morro Group.
Morro Group has submitted a proposal to perform this additional work at a cost of$24,802.
FISCAL IMPACT
There is $300,000 budgeted for the environmental review phase of this project. Of that amount,
$174,400 is still available. This amendment would increase Morro Group's contract.amount by
$24, 802 for a total contract value of$129,382.

Proposal—Extended Phase I Survey Garcia and Associates
Mid-Higuera Street Widening Project August 4,2004,
revised March 2005
C�-5
1.0 INTRODUCTION
The following Extended Phase I Survey proposal describes the details of the extended
survey proposed for the Mid-Higuera Street Widening project in San Luis Obispo,
California. There are two objectives for the Extended Phase I Survey proposal. The first
is to determine the boundaries of archaeological site MHWP-01 (temporary designation)
relative to the direct Area of Potential Effects (APE), and to characterize the marine shell
in the cultural deposit. The second purpose is to reveal if buried prehistoric,or historic
cultural deposits exist within the direct APE of an undeveloped parcel (APN 002-482-
027).
Archaeological site MHWP-01 was located during the cultural resources inventory by
Garcia and Associates (GANDA) for the Mid-Higuera Street Widening project in San
Luis Obispo, California (Denardo 2004). The survey will establish whether intact
subsurface deposits or features exist within the project's direct APE and it will determine
the nature of the marine shell identified in the deposit. The survey will delineate the site
boundaries within the direct APE so a detem-iination can be made if the proposed project
would impact the resource. If the project, as proposed, will impact the site, the
delineation will assist in exploring other options, if necessary, for avoidance. The
Extended Phase I Survey. will also determine if marine shell observed at the site
represents prehistoric or historic occupation. Archaeological site.MHWP-01 was located
during the cultural resources inventory by Garcia and Associates (GANDA) on May 15,
2004.
In addition, during a supplemental survey outside the study area on December 22, 2004,
historic artifacts and marine shell (Creek Bank Profile Location 1), were observed
eroding from the east bank of San Luis Obispo Creek, at APN 002-482-027, extending to
a depth of 2.5 meters. A second cultural deposit of mostly modem refuse (Creek Bank
Profile Location 3), with some possible historic artifacts and marine shell, was identified
at the western edge of APN 003-711-024, behind a garage near the south end of the study
area. The eroding artifacts were observed to extend from the top of the creek bank to the
waterline, a distance of 3.5 meters. In both instances, the cultural deposits were outside
the limits of the project's study area and direct APE (Area of Potential Effects).
However, it is uncertain if they represent localized dumping along the stream bank, or if
they demonstrate the propensity for cultural deposits buried in alluvium or fill within the
project area. The alluvial flat in the area of the creek bank profiles is heavily disturbed
through modern development. However, APN 002482-026, which adjoins APN 002-
482-027, is largely undeveloped and displays the most potential for subsurface cultural
deposits. The extended survey will determine the presence or absence of cultural
materials within this parcel.
No other archaeological sites were identified within the APE.

2.0 BACKGROUND
2.1 Undertaking Location and Description
The proposed road widening will take place along Higuera Street in San Luis Obispo,
California. The proposed project would create an 86-foot wide right-of-way (ROW) by
widening the existing 60-foot Mguera Street ROW by approximately 26 feet between
Marsh Street and 185 feet south of High Street, a distance of approximately 1,181 linear
feet (360 meters). The proposed ROW is six feet wider than the previously adopted 80-
foot setback line for the corridor: The additional 26 feet would allow two additional
travel lanes and a landscaped median to limit driveway access and cross=traffic along
Higuera Street, safely accommodate left turns for standard vehicles and trucks, and add
landscaping to beautify the corridor. Included in the ROW are four 11-foot travel lanes, a
14-foot wide landscaped median, two 5-foot bikeways, and two 8-foot sidewalks. The
intersection of Mguera Street with Pacific Street would be realigned to create a standard
perpendicular intersection approach with new curb, gutter, and sidewalk improvements.
WalkerStreet would be closed and made into a cul-de-sac to allow for future construction
of a pedestrian plaza. The maximum depth of excavation is expected to be less than one
foot to level surfaces to the depth of the existing street.
The proposed project will require relocation or demolition of several properties along the
western side of Higuera Street. The Craftsman residence at 292 Higuera Street (APN
002-482-015) will not be removed for this project. The widening will require removal of
landscaping and relocation of a few mobile homes.
The City of San Luis Obispo is sponsoring the Mid-Higuera Street Widening Project.
The project will be funded with local and federal transportation funds, with financial
assistance from the Federal Highway Administration, and oversight by the Caltrans Local
Assistance Program.
2.2 Section 106 Compliance
Because the proposed Mid-Higuera Street Widening project will utilize federal funds, it
is considered an undertaking (per 36 CFR 800[y]) subject to the authority of federal and
state historic preservation law. The Federal Highway Administration (FHWA) requires
that project proponents assist the administration in meeting its obligations under the
National Historic Preservation Act (NHPA) of 1966, as amended, to consider project
effects on historic properties pursuant to Section 106 of the NHPA and its implementing
regulations found in 36 CFR 800. The proposed Extended Phase I Survey will facilitate
compliance requirements of 36 CFR 800.4(b) by providing accurate information on the
location of historic properties..

CLI- 7
The purpose of the Extended Phase I Survey is to define site lirnits relative to the direct
project effects; and to determine the presence/absence of a subsurface cultural deposit.
The Extended Phase I Survey will determine if intact or disturbed cultural deposits exist
within the direct APE. Detailed site boundaries are required to guide proposed project
design,and resource management decisions (Caltrans 2001:5-6).
2.3 Site Descriptions
➢ MHWP-01
No previously recorded archaeological sites were identified within the project area during
a record search at the Central Coast Information Center (CCIC) of the Historic Resource
Inventory System (CHRIS) at the University of California, Santa Barbara on April 26,
2004. However; GANDA recorded archaeological site MHWP-01 (temporary
designation)during an intensive pedestrian survey on May 14; 2004.
The site consists of a historic midden or trash dump in the front and side yard of the
Craftsman-style house at 292 Higuera Street; surface artifacts extend into the direct area
of potential effects. Concentrations of marine shell, glass, and historic ceramics are
visible on the ground surface surrounding the house, but the cultural deposit appears to
predate the existing building (e.g., blue transferware ceramic ca. late 1800s). It is
probable that the marine shell associated with the midden is historic; however, the shell
could also represent a prehistoric component.
The back yard of the 292 Higuera Street residence was not surveyed; however; that area
is outside the direct APE. In addition, paved areas and dense lawn areas at the
neighboring parcels prevented a more definitive delineation of site boundaries. No
artifacts were collected during the archaeological pedestrian survey. Pertinent
archaeological site information and artifact descriptions are recorded on DPR 523
Primary and Archaeological Site record forms, and a sketch map is provided that depicts
the presently known site boundaries. Extended Phase 1 Testing will determine the nature
of the shell in the deposit.
In a separate historic resources study for this project, the extant Craftsman-style house
was determined not to be eligible:for listing in the National Register of Historic Places
(NRNP); however, the building is not slated for demolition (Merriam 2004; Monreal,
pers. com. 2005).
Historic background research revealed that prior to construction of the Craftsman-style
house at 292 Higuera Street an earlier house occupied approximately the same location
(Sanborn map 1891). By 1873, Eustacio (Anistachio, Austachio) Sesena (Sesinai
Secenia) owned the parcel at 56 (292) Higuera Street. The property extended west from
Higuera Street to San Luis Obispo Creek '(Harris & Lakin 1873). An 1877 oblique
drawing of San Luis Obispo depicts a single building with an ample setback on Mr.
Proposal=Extended Phase I Survey Garcia and Associates
Mid-Higuera Street Widening Project August 4,2004,
revised March 2005
Sesena's lot (Glover 1877). Mr..Sesena was a resident of San Luis Obispo from as early
as 1860, and was married and had a family there by 1869, so it is plausible that he resided
at that same location at an earlier date. Mr.. Sesena was bom in California 1840; his
father emigrated from Mexico and his mother was Native American. His wife, Refugia
Villa De Sesena, was full-blooded Native American (U.S. Census Records 1860, 1870).
In 1880, Anistachio Sesena was employed as a teamster, and Mrs. Sesena engaged in
housekeeping (U.S. Census 1880). In 1891, a humble dwelling, belonging to Mr.
Sesena, is indicated at 56(292) Higuera Street (Sanborn 1891): In 1901, Refugia Sesena
shared the property with her four children, and the family members were employed as
laborers and servants(City and County Directory 1901).
In 1911, Mrs. Sesena transferred the southern half of the property (Lot D) to Mary
Fogarty (Assessors Map Book 1900-1949). Within the next few years, the former
residence was replaced by a home of Craftsman styling. Constructed in about the same
location as the former structure, the new dwelling retained the same liberal setback
(Sanborn Map Co. 1926).
➢ Creek Bank Profile Locations
On December 22, 2004, GANDA conducted a supplemental cursory survey along San
Luis Obispo Creek to examine soils in profile along the east bank to determine if there is
a potential for unearthing subsurface cultural deposits within the APE. Historic artifacts,
marine shell, and some modern debris were found eroding from the east bank of San Luis
Obispo Creek south of Marsh Street behind parcel 002-482-027. The cultural deposit was
designated Creek Bank Profile Location 1. During the initial pedestrian survey, no
corresponding artifacts were noted on the ground surface within the parcel, including the
area of direct impact, but visibility was limited because paved surfaces and commercial
development occupy most of the parcel .
Creek Bank Profile Location 2 displayed alluvial sediments from the.tetrace bank to the
waterline at APN 002-482-015; but no cultural materials were observed.
A mixture of automotive refuse with historic artifacts and marine shell (Creek Bank
Profile Location 3) was noted behind a garage at the edge of the creek bank at APN 003-
711-024. During the initial pedestrian survey, commercial development in this parcel
(comprising buildings and paved surfaces within the area of direct impact) precluded an
examination of the ground surface. The prospect of recovering intact deposits at this
parcel is low due to the high level of development.
Of the remaining parcels on the west side of the Mid-Higuera Street project area, only
one (APN 002-482-026) remains undeveloped and has the most potential for subsurface
archaeological deposits. No artifacts were identified at this parcel during the pedestrian
survey, but it is possible that alluvium or modem fill has buried or obscured artifacts that
may exist within the expanse of this undeveloped flat. APN 002-482-026 belonged to W.

G. Archer in 1873 (Harris, & Lakin 1873) and it is likely that nearby Archer Street was
named in his honor. No buildings are depicted on the parcel in 1877 (Glover 1877);but
by 1888, a single story dwelling existed on the lot (Sanborn 1888). Three years later, a
lot line is indicated, but the dwelling is absent (Sanborn 1891). By 1926, an auto repair
business (402 Higuera Street), a stone cutting facility (354 Higuera. Street), and an
automobile garage are present on the parcel (Sanborn 1926). In 1950, only the garage
still occupied the parcel (Merriam 2004:11; Sanborn 1950).
APN 002-482-026 is approximately 250 meters south of recorded historical
archaeological site, CA-SLO-914, located outside the project area. CA-SLO=914 also
exhibited historic artifacts and shell eroding from the creek bank in addition to artifacts
and features observed on the surface of the alluvial flat.(Johnson 1980).
3.0 SCOPE OF WORK
3.1 Extended Phase I Survey Methodology—MHWP-01
3.1.1. Basis for Extended Phase I Survey
Presently, the nature of the cultural materials at MHWP-01 is unknown. It is possible
that foundations, privies, or trash deposits associated with the early development of San
Luis Obispo exist below the ground surface. It is also plausible that marine shell
observed on the ground surface may represent a prehistoric site component. An Extended
Phase I Survey at MEW-01 will establish whether intact subsurface deposits exist
within the project's direct APE and it-will reveal the nature of the marine shell identified
in the deposit. Based on the surface distribution of artifacts observed during Garcia and
Associates' 2004 inventory, the eastern boundary of MHWP-01 is located at the western
edge of the sidewalk next to Higuera Street.
3.1:2 Survey Methodology
Prior to the Extended Phase I Survey, a survey crew will stake and flag the direct APE
boundary at APN 002-482-023. Before conducting test excavations, a sample of
diagnostic materials will be collected from the ground surface to serve as a comparative
data set for subsurface deposits,. Garcia and Associates proposes to excavate a minimum
of four 50 cm x 50 cm square shovel test probes (STP) inside the western boundary of the
direct APE at archaeological site MHWP-01. The locations of STPs will be plotted on
project maps and Global Positioning System (GPS) units will be used to record the
locations of all excavation units.. Soils will be excavated in 20 cm levels, and screened
through 1/4 in (6.2 mm) mesh hardware cloth or through 1/8 in (3.1 mm if a prehistoric
component, comprising artifacts other than marine shell, is identified. Excavation of
STPs will continue to a depth of one meter or until.two culturally-sterile levels are
encountered.
Proposal—Eiitended Phase i Survey Garcia and Associates
Mid-Higuera Street Wideniag Project August 4,2004,
revised March 2005
Recovered artifacts will be retained, bagged, and labeled according to provenience. Only
a sample of bulky or redundant materials (i.e., can fragments, concrete chunks) will be
collected; quantities and material types will be recorded in the field prior to redepositing
those items at the bottom of the STPs. Field observations will be recorded on standard
Historic Artifact Inventory forms. Soil colors will be recorded using Munsell Soil Color
charts. All excavations will be backfilled and the area restored as nearly as possible to its
original appearance. Color digital photographs will be taken to document the fieldwork.
Following excavation, an updated California Department of Parks and Recreation DPR-
523 primary record form will be completed for MIWP-01.
Based on an examination of soils in the study area and creek bank stratigraphy, we
assume that sediments will be a loamy alluvial sand with increased clay content with
depth. Given the nature of the sediments, we assume that the Field Director, assisted by
two crewmembers,can complete the fieldwork effort in two days.
In the event human remains are encountered, Garcia and Associates will adhere to the
provisions of Sections 7052 and 7050.5 of the California Health and Safety Code.
Section 7052 states that disturbance of Indian cemeteries is a felony. Section 7050.5
requires that construction or excavation be stopped near discovered human remains until
the coroner can determine whether the remains are those of a Native American. If the
remains are Native American, Section 7052 states that the coroner must contact the
California Native American Heritage Commission.
3.1.3 Decision Thresholds
Excavation of STPs at MHWP-01 will continue to a depth of 100 centimeters or until two
levels of culturally-sterile soils are encountered.
Building foundations or other structural features, privies., and trash dumps, constitute
intact historic archaeological deposits. Intact prehistoric deposits include cultural midden
with densities of artifacts, or features such as house floors;hearths or rock-lined roasting
pits. If intact deposits are encountered, the Extended Phase I Study will halt and
GANDA, Morro Group,.the City of San Luis Obispo, and Caltrans will consult to
determine if a full evaluation of the site is required.
3.2 Extended Phase I Survey Methodology—APN 002482-026
3.2.1.Basis for Extended Phase I Survey
A cursory examination of soils along the east bank of San Luis Obispo Creek revealed
two areas of historic artifacts, marine shell, and modem refuse, within loamy alluvial
sand soils, eroding from the terrace downslope for a distance, of between 2:5 and 3.5
meters. This suggests that subsurface deposits may exist within the study area. Due to its
proximity to the confluence of San Luis Obispo and Stenner creeks, and because APN

002-482-026 is largely undeveloped, it possesses the most potential for intact
archaeological deposits within the project area. An Extended Phase I Study within the
direct APE of the alluvial flat at APN 002-482-026 will determine the presence or
absence of cultural deposits in the study area.
3.2.2 Survey Methodology
Prior to the Extended Phase I Survey, a survey crew will stake and flag the direct APE
boundary at APN 002-482-026. Garcia and Associates proposes to excavate
approximately eight 50 cm x 50 cm square shovel test probes (STP) placed ten meters
apart inside the western boundary of the direct APE along parcel 002482-026 fronting
Higuera Street. The locations of STDs will be plotted on project maps and Global
Positioning System (GPS) units will be used to record the locations of all excavation
units. Soils will be excavated in 20 cm levels, and screened through 1/8 in (3.1 mm)
mesh hardware cloth.
If artifacts are recovered, they will be retained, bagged, and labeled according to
provenience. Only a sample of bulky or redundant materials (i.e., can fragments,
concrete chunks) will be collected; quantities and material types will be recorded in the
field prior to redepositing those items at the bottom of the STPs. Field observations will
be recorded on standard STP Inventory forms. Soil colors will be recorded using
Munsell Soil Color charts. All excavations will be backfilled and the area restored as
nearly as possible to its original appearance. Color digital photographs will be taken to
document the fieldwork. Following excavation, a California Department of Parks and
Recreation DPR-523 primary record form will be completed for any new sites.
Based on an examination of soils in the study area and creek bank stratigraphy, we
assume that sediments will be a loamy alluvial sand with increased clay content with
depth. Given the nature of the sediments, we assume that the Field Director, assisted by
two crewmembers,can complete the fieldwork effort in three days.
In the event human remains are encountered; Garcia and Associates will adhere to the
provisions of Sections 7052 and 7050.5 of the California Health and Safety Code.
Section 7052 states that disturbance of Indian cemeteries is a felony. Section 7050.5
requires that construction or excavation be stopped near discovered human remains until
the coroner can determine whether the remains are those of a Native American.. If the
remains are Native American, Section 7052 states that the coroner must contact the
California Native American Heritage Commission.
3.2.3 Decision Thresholds
Excavation of STPs will continue to a depth of one meter, or until cultural materials are
recovered. If archaeological materials, i.e., artifacts, features, etc., are located in any of
the excavation units placed in the direct APE, then excavation will terminate in that unit.
Proposal-Exuded Pbase I Survey Garcia and Associates
Mid-Higuera Street Widening Project August 4,2004,
revised March 2005
C q- l2
Recovery of archaeological materials will be taken as evidence of the presence of an
archaeological site within the APE. In other words, excavation is being conducted to
determine the presence or absence of cultural materials in the APE; excavation will be
terminated in a STP if cultural soils are encountered. This decision will be determined by
an inspection of the stratigraphic profile by the Field Supervisor.
Building foundations or other structural features, privies, and trash dumps, constitute
intact historic archaeological deposits. Intact prehistoric deposits include cultural midden
with densities of artifacts, or features such as house floors, hearths or rock-lined roasting
pits. If intact cultural deposits are encountered, the Extended Phase I Study will halt and
GANDA, Morro Group, the City of San Luis Obispo, and Caltrans will consult to
determine if a full evaluation of the site is required.
40 LABORATORY AND DATA ANALYSIS
Artifacts recovered in the _field will be transported to Garcia and Associates' laboratory
for processing. All collected artifact/sample specimens will be washed (as appropriate),
sorted, counted, weighed, and tabulated. Artifacts will be cataloged, classified, weighed,
measured, numbered, and illustrated following professional standards. Historic materials
Will be cataloged separately from prehistoric materials (if present) following functional
categories generally accepted for late nineteenth century sites in the Western United
States as developed by South (1977) and refined by Costello et al. (1996). The
assemblages will be analyzed with reference to functional and morphological attributes,
and chronological indicators. Descriptions will be made for classes of artifactual and
ecofactual materials. The historical archaeological collection will be cataloged and
processed using the following material type categories: shell, animal bone, botanical
remains, ceramics, glass, metal, architectural debris (brick, concrete, wood, etc.) and
miscellaneous small personal items. Fragile items that might require special handling
will be removed prior to washing.
If a prehistoric component is discovered; then, at a minimum, faunal material, beads,
flaked stone, ground stone, and other items will be counted, weighed, and sorted by
species or material type. Diagnostic artifacts will be analyzed.
Analytical research will also focus on technology, subsistence-settlement, and exchange
activities as represented by the assemblages. Assemblages will be cataloged and
processed as follows:
• Time-Sensitive Artifacts (e.g., projectile points, beads): classified .according to
recognized typological schemes; data useful in defining assemblages and
assessing site function and depositional integrity.
Proposal—Extended Plum[Survey Garcia and Associates
Mid-Higuera Street widening Project August 4,2004,
revised March 2005
, -13
• Flaked Stone: organized by functional and morphological attributes, material, and
artifact type; measured, weighed, and condition noted; bifaces subdivided based
on reduction stage.
• Debitage: counted, weighed, and sorted by material type; analyzed by category
(e.g., primary reduction, early biface thinning, etc.).
• Battered and Ground Stone Artifacts: separated into functional categories (e.g.,
pestle, mano, mortar); described by tool morphology.
• Shell and Bone Artifacts: organized by functional category (e.g., fishhook, awl,
etc.); described by tool morphology, including measurements, modifications and
fragment types; used to assess site deposit, and to infer site function.
• Faunal Analyses: specimens organized by genus, species, element, age, weight,
condition, unidentifiable elements, and intrusive rodent categories; summarized
by number of identifiable specimens per species (NLSP), minimum number of
individuals (MAI); used to define assemblage constituents, site function, and
relative contribution of various taxa to native diet.
5.0 NATIVE AMERICAN COORDINATION
Caltrans policy, based on state and federal law, is to request that a Native American
monitor be present at the excavation of all prehistoric sites. Presently, it is uncertain if
MHWP-01 represents both historic and prehistoric components. In addition, during
Native American consultation for this project, many individuals expressed concerns
about unearthing burials in the area. Excavations in APN 002-482-026 will help to
establish if subsurface prehistoric sites are present in the project area. Ms. Lei Lynn
Odom has spoken with GANDA about providing Native American monitoring for the
proposed Extended Phase I Survey. The Native American Heritage Commission
(NAHC) lists Ms. Odom as a Chumash Native American contact for this area. GANDA
has assumed the presence of a Native American Monitor during all ground-disturbing
activities in its cost estimate.
6.0 CURATION
Garcia and Associates will arrange for archaeological materials recovered during the
Extended Phase I Survey to be curated at the San Luis Obispo County Archaeological
Society's (SLOCAS) research and collection facility in San Luis Obispo. Garcia and
Associates will not be responsible for ongoing curation costs and, has assumed in its
budget that no more than one standard curation box will require pacing and shipping to
SLOCAS. For budgeting purposes, we have assumed curation costs will not exceed
$1000; however, this is only an estimate. It is assumed that, due to the minimal amount
of excavation proposed, the quantity of artifacts recovered will below.
