IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
An allocation of $255,440 of Local Sales Tax funds and $55,835 from Other Government
Agencies is included for the project in the FY 2020/21 Capital Improvement Program
budget. It is anticipated that approximately $700,100 ($536,500 Developer funds and
$163,300 Local Sales Tax funds) will be carried over from FY 2019/20 for a total available
budget of approximately $1,011,300 for construction, testing, contract administration, and
construction contingencies. Staff time will be necessary to provide construction
management and inspection services for the project.
RECOMMENDATION:
It is recommended the City Council adopt a Resolution:
1. Approving the construction plans and specifications for the Castillo Del Mar Extension
Project, PW 2020-05;
2. Authorizing the City Clerk to solicit construction bids; and
3. Making the findings necessary to confirm that the project’s Mitigated Negative
Declaration adopted on August 22, 2006 for General Plan Amendment Case No. 06-
001 is sufficient and that no further environmental review is required in compliance
with the California Environmental Quality Act (CEQA) and CEQA Guidelines Section
15162.

BACKGROUND:
The need to develop an extension of the existing Castillo Del Mar roadway was identified
in a 2013 Memorandum of Understanding (MOU) for a development proposed by the J.H.
Land Partnership (later named the Heights at Vista Del Mar). The MOU was executed
between the Lucia Mar Unified School District, City of Arroyo Grande, J.H. Land
Partnership and John Taylor. Part of the MOU included a conceptual framework for the
parties to coordinate and develop a proposed extension of the existing Castillo Del Mar
Drive from its present terminus to Valley Road in order to serve the existing Vista Del Mar
development and the proposed J.H. Land Partnership development. The $536,500 of
developer funds in the project budget was received from The Heights at Vista Del Mar
Group, LLC to be used for construction of the roadway extension as outlined in the MOU.
The extension will also provide an additional access route behind the high school to
relieve existing traffic congestion on Orchard Street caused by the high school and
provide a safe, alternative access route for students and the general public.
In order to bid the project and provide California design immunity, per Government Code
Section 830.6, the City Council approves the plans and specifications prior to the
construction bidding process. In addition, confirmation of the environmental determination
at the time of authorization to bid the project satisfies the requirements of CEQA.
ANALYSIS OF ISSUES:
The general Base Bid scope of work involves the demolition of portions of the existing
roadway and Arroyo Grande High School parking lot as well as construction of public
improvements within a new right-of-way that will realign Castillo Del Mar to a new
connection point with Valley Road. The scope of work also includes a multi-use path,
drainage improvements, waterline relocation, and landscaping.
The project scope includes a number of Add Alternative Bid items. The use of a Base
Bid and Add Alternate Bid items allows the City to award the Base Bid as well as Add
Alternate Bid items in any order or quantity based on available funding. Below is a list of
the Add Alternate Bid items:
Bid Alternate 1: Increase Street Section from 3.0" to 4.5" Hot Mix Asphalt (HMA)
Bid Alternate 2a: Street Trees (Swan Hill Olive)
Bid Alternate 2b: Irrigation for Street Trees
Bid Alternate 2c: Irrigation Meter for Street Trees
Bid Alternate 2d: Solar Powered Irrigation Controller for Street Trees
Bid Alternate 3a: Parking Lot Striping
Bid Alternate 3b: Parking Lot Striping - Arrows
Bid Alternate 3c: Parking Lot Striping - "STOP" Legend
Bid Alternate 4: Relocate Portable Storage in Parking Lot

Bid Alternate 5: Street Lights
Bid Alternate 6a: School Access Drive - HMA
Bid Alternate 6b: School Access Drive - Aggregate Base
Bid Alternate 6c: Parking Bumpers - New School Parking Area
These Add Alternative Bid items would allow the City to increase the depth of the asphalt
to accommodate future traffic volumes and to add street trees, street lights, and
improvements to the high school parking lot, if approved by the Lucia Mar School District
for funding.
The total estimated construction cost for the project, including the bid alternates, is
$935,000. The proposed contract time is 180 working days for the Base Bid with an
additional three working days per awarded Add Alternate except for Add Alternate 5 which
would add an additional 30 working days. If successful bids are received and a
construction contract is awarded, work is expected to begin in December 2020 and end
in September 2021. Plans and specifications are available for review at the Public Works
Department.
ENVIRONMENTAL ISSUES:
The City Council adopted a Mitigated Negative Declaration on August 22, 2006 for
General Plan Amendment Case No. 06-001, which specifically addressed the planned
extension of Castillo Del Mar from Orchard Street to Valley Road. Section 15162 of the
CEQA Guidelines addresses the use of a previously-approved environmental document
for later project-related actions and states:
(a) When an EIR has been certified or a negative declaration adopted for a project, no
subsequent EIR shall be prepared for that project unless the lead agency determines, on
the basis of substantial evidence in the light of the whole record, one or more of the
following:
(1) Substantial changes are proposed in the project which will require major
revisions of the previous EIR or negative declaration due to the involvement of new
significant environmental effects or a substantial increase in the severity of
previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under which the
project is undertaken which will require major revisions of the previous EIR or
Negative Declaration due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified significant
effects; or

(3) New information of substantial importance, which was not known and could not
have been known with the exercise of reasonable diligence at the time the
previous EIR was certified as complete or the Negative Declaration was adopted,
shows any of the following:
(A) The project will have one or more significant effects not discussed in the
previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe
than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible
would in fact be feasible, and would substantially reduce one or more
significant effects of the project, but the project proponents decline to adopt
the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different
from those analyzed in the previous EIR would substantially reduce one or
more significant effects on the environment, but the project proponents
decline to adopt the mitigation measure or alternative.
(b) If changes to a project or its circumstances occur or new information becomes
available after adoption of a negative declaration, the lead agency shall prepare a
subsequent EIR if required under subdivision (a). Otherwise the lead agency shall
determine whether to prepare a subsequent negative declaration, an addendum, or no
further documentation.
(c) Once a project has been approved, the lead agency's role in project approval is
completed, unless further discretionary approval on that project is required. Information
appearing after an approval does not require reopening of that approval. If after the project
is approved, any of the conditions described in subdivision (a) occurs, a
subsequent EIR or negative declaration shall only be prepared by the public agency
which grants the next discretionary approval for the project, if any. In this situation no
other responsible agency shall grant an approval for the project until the
subsequent EIR has been certified or subsequent negative declaration adopted.
(d) A subsequent EIR or subsequent negative declaration shall be given the same notice
and public review as required under Section 15087 or Section 15072. A
subsequent EIR or negative declaration shall state where the previous document is
available and can be reviewed.

City staff has reviewed the adopted Mitigated Negative Declaration and has found the
following:
1. No substantial changes are proposed to the project that would require revisions
of the previously adopted Mitigated Negative Declaration. The project and the
road alignment are the same as they were back at the time of approval in
August 2006.
2. No substantial changes are proposed to the project with respect to the
circumstances that would require revisions of the previously adopted Mitigated
Negative Declaration. There have been no substantial changes to the General
Plan that would impact this project. The mitigation measures adopted with the
Mitigated Negative Declaration have been incorporated into the plan set that is
part of the bid package.
3. No new information of substantial importance has been identified since the
approval of the original Mitigated Negative Declaration. The project is
consistent with the General Plan and current City Standards.
4. There are no discretionary permits required for this project.
Based on the above, City staff recommends that the Council affirm that the previously-
adopted Mitigated Negative Declaration is sufficient and that no subsequent or
supplemental environmental review is required to move forward with the project.
ALTERNATIVES:
The following alternatives are provided for the Council’s consideration:
1. Approve staff’s recommendations;
2. Do not approve the construction plans and specifications, direct staff to evaluate
alternatives, and return to City Council for approval in the future;
3. Modify staff’s recommendation and approve; or
4. Provide direction to staff.
ADVANTAGES:
The extension of Castillo Del Mar will result in improved access for the Vista Del Mar and
the Heights at Vista Del Mar developments, and will help relieve congestion related to
high school traffic. It will also provide additional on street parking spaces that the high
school can utilize to reduce on street parking in adjacent neighborhoods.
DISADVANTAGES:
The City will be responsible for the additional road maintenance costs.

by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.
The proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
The proposed project MAY have a "potentially significant impact" or "potentially significant unless
mitigated" impact on the environment, but at least one effect ~) has been adequately analyzed in
an earlier document pursuant to applicable legal standards, and 2) has been addressed by
mitigation measures based on the earlier analysis as described on attached sheets. An
ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that .
remain to be addressed. ·
D Although the proposed project could have a significant effect on the environment, because all
potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE
DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated
pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation
measures that are imposed upon the proposed project, nothing further is required.

Project Environmental Analysis
The City's environmental review process incorporates all of the requirements for comp1eting the
Initial Study as required by the California ·Environmental Quality Act (CEQA) and the CEQA
Guidelines. The Initial Study includes staffs on-site inspection of the project site and surroundings
and a detailed review of the information in the file for the project. In addition, available background
information is .reviewed for each project. Relevant information regarding soil types and
characteristics, geologic information, significant vegetation · and/or wildlife resources, water
availability, wastewater disposal services, existing land uses and surrounding land use categories
and other information relevant to the environmental review process are evaluated for each project.
The Community Development Department uses the checklist to summarize the results of the
research accomplished during the initial environmental review of the project.
Persons, agencies or organizations interested in obtaining more information regarding the
environmental review process for a project should contact the City of Arroyo Grande Community
Development Department at 214 East Branch Street Arroyo Grande, CA 93420 or call (805) 473-
5420. ·
A. PROJECT
DESCRIPTION: Proposal to extend the existing City roadway known as Castillo Del Mar to improve
circulation around the southeast portion or Arroyo Grande High School campus and adjoining
residential neighborhood. Castillo Del Mar will be extended from its present terminus to Valley Road
to serve the existing Vista Del Mar development located within the City limits and the J.H. Land
Partnership proposed development located within the unincorporated area of San Luis Obispo
County. The proposed roadway extension will traverse the Lucia Mar Unified School District (LMSD)
property for the existing Arroyo Grande High School site (APN 006-095-001) and a portion of a private
agricultural parcel owned by John Taylor {Assessor's Parcel No. 006-095-002). ·
The project includes the following components:
1) Tentative parcel map for an approximate 50-acre property including and southeast of
Arroyo Grande High School campus to create a 37-acre parcel {existing Arroyo Grande High School
campus) and an 11-acre parcel and to rezone a 10-acre portion (existing sports fields and parking
lots) of the 37-acre parcel from Agriculture to Public Facilities {identical to the zoning for the remainder
of the Arroyo Grande High School campus): and amend the 2001 General Plan Land Use Element to
re-designate the 11-acre proposed parcel from Community Facilities to Low Density Single Family
Residential and to rezone the 11-acre proposed parcel from Agriculture (Ag) to Residential Hillside
(RH) [See Attachment A];
2} Subdivide an approximate 7.5 acre parcel adjoining and south of Arroyo Grande High
·school campus on the east side of Valley Road to create a 1.2-acre parcel and a 6.3-acre parcel and
amend the 2001 General Plan Land Use Element to designate the 1.2-acre parcel from Agriculture to
Community Facilities and rezone the 1.2 -acre parcel from Agriculture {Ag) to Public Facility (PF);
3} To design, construct, extend and improve Castillo Del Mar Drive from near Orchard Street
to Valley Road to enable circulation around Arroyo Grande High School and allow local street access
southeast to a proposed County subdivision known as Busick Tract No. 1789 located outside City
limits:
4) To accept an in-lieu mitigation contribution for loss of one acre of prime farmland
associated with proposed road extension and _potential conversion of prime.farmland to future Public
Facility use.
Design and review of any subsequent residential subdivision is not part of the project and therefore
any future development is subject to separate discretionary and environmental review. This Initial
Study evaluates potential environmental impacts for the proposed amendments to the Land Use
Element and Zoning maps that are intended to provide consistency betv.ieen the General Plan and
Zoning Ordinance, the General Plan and Zoning amendments that are related to the Tentative Parcel
Map and land use changes associated with the proposed construction of Castillo del Mar, as well as
the proposed road extension and improvemen~s.

Setting. The project includes approximately 11.6-acres of undeveloped hillside behind the Arroyo
Grande High School sports fields and student parking area which is proposed for disposition and
rezoning from Agriculture (A) to Residential Hillside (RH). An existing roadw~y. Castillo del Mar Drive,
and a connecting segment currently used for emergency· access, would be improved as a public street
· right-of way and offered for dedication. Additionally, the roadway improvement includes a 44 ft. wide
roadway extension, that is 987 lineal ft. for Castillo Del Mar from its current terminus, along the
southern edge of the Arroyo Grande High School campus, and extended in an "Sn curve to intersect
Valley Road (Attachment A). Additionally, approximately one-acre .of prime farmland including the
proposed road extension, immediately adjacent the Arroyo Grande High School is proposed to be re-
designated and rezoned from Agriculture to Community Facility/Public facility. Both the 11.6 acres of
vacant hillside and the area east of Valley Road through which the Castillo del Mar Drive is proposed
to be extended, are open to public view.
-Impact. Policy C/OS1-1 of the Agriculture, Conservation and Open Space Element of the General
Plan encourages protection of visually accessible scenic resources. A 'scenic resource' is further
defined as "agricultural land, open spaces, hillsides, ridgelines, canyons, valleys, landmark trees,
woodlands, wetlands, streambeds and banks, and well as aspects of the built environment that are of
a historic nature, unique to the City, or contribute to the rural, small town character of the City.n The
City has not officially recognized this property as being a sensitive scenic resource, and the road
extension will only traverse vacant and farmed agricultural land for approximately 100 feet. Since the
road extension crosses property at the bottom of a moderately sloped parcel and along the periphery
of existing parking lots for Arroyo Grande High School, it is not expected that the road extension will
cause a significant aesthetic impact.
The 11.6 acres proposed to be re-designated and rezoned to Residential Hillside (RH) are surrounded
on three sides by. RH zoning, which includes the Vista del Mar subdivision to the east. This proposal
would enable future subdivision application, subject to project-specific environmental review, for a
maximum of eight residences, exclusive of possible density bonuses for affordable housing.

ensure that all residential hillside development, regardless of density, does not excessively intrude on
the natural slope and terrain of the hillside including density that is commensurate with the steepness
of the slope and prohibiting the excessive use of retaining walls, intrusive grading and removal of
native oak trees (LU2-2.4); and allow development at a maximum of 1.5 dwelling units per acre, with
potential for lower densities if required in order to address site-specific environmental impacts.

Setting. Both the 11.6-acre hillside portion of the project and the Arroyo Grande High School sports
fields (approximately 10 acres) have conflicting zoning and General Plan classifications. The General
Plan classification is Community Facilities (CF) and the zoning district is Agriculture. This conflict was
documented in the City's study on Agricultural Resources (2003), and determined that the General
Plan designation for this parcel was not jnconsistent or in need of modification, and therefore the
zoning would be changed from Agriculture to PF during the Development Code Update process to
Citv of Arrovo Grande, Initial Study fot GPA06'-001; DCA06-001; TPM 06-004 Page5
Item 8.k. - Page 15
address changes required by the 2001 General Plan update (not yet complete}. Therefore the
change in zoning from Agriculture for the 10-acre sports fields and the 11.6-acre vacant hlilside area
is not considered a conversion of prime agricultural land due to it's consistency with the designation
as CF in the 2001 General Plan, review under the 2001 General Plan EIR and subsequent analysis in
the 2003 Report on Agricultural Resources {including it's non-prime classification as class IV -VI soils
according to the USDA Soil Survey of San Luis Obispo County). However, the proposed General
Plan and Zoning Amendments for the 1.2 acre portion of John Taylor's 7.5-acre parcel (APN 006-095-
001 ), currently in row crop production, from Agriculture to Community Facilities/PF is considered a
conversion of prime agricultural land.
. Impact. Due to the proposed re-zoning and conversion of 1.2 acres of irrigated and farmed
agricultural land, the impact must be considered significant unless it can be determined that in
consideration of all the implications of the conversion, there is feasible mitigation that can reduce the
impact to less than significant. The General Plan Agricultural, Conservation and Open Space
Element objective Ag1 requires the City to "Avoid and/or mitigate loss of prime farmland soils and
conserve non-prime Agriculture use and natural resource lands." Several policies and implementation
measure~ specifically relate to loss of the City's agricultural land inventory and must be considered in
light of the specifics of the proposal in order to determine if the impact can be mitigated to the extent
that it is no longer significant or if it remains significant even after all applicable mitigation is required.
Given that the proposal includes the improvement, extension and dedication of a public road to
address a circulation deficiency, Ag1~1.2 relates to the proposed action as it states: "Public facilities
are permitted on agricultural and natural resource lands when required by public health, safety and
welfare of the public". Adequate and safe circulation and secondary access around the high school ls
an applicable application of this policy and provides for consideration of mitigation if the potential
conversion can not be fully avoided due to public health safety and welfare.
Additionally, the proposed conversion of 1.2-acres of agricultural land is located a triangular piece of
property between the Arroyo Grande High School campus and Valley Road, and as such it is not
anticipated that it will fragment or impair other agricultural lands. Since nearly the entire proposed
1.2-acre parcel would be included within 100 ft. of operational fannland, there could not be any
residential development on the property, consistent with the City's agricultural buffer requirements in
Section 16.12.170.E.
General Plan policy Ag1-4 and related policies include provisions for mitigation which may include
permanent protection of prime farmland solls at a ratio of at least 1:1 with regard to the acreage of
land removed from the capability for agricultural use which may be satisfied by payment of in-lieu fees
as proposed. Development Code provisions suggest up to a 2:1 mitigation of comparable Ag
capability.
Mitigation/Conclusion.
MM 2.1: Payment of an in-lieu fee sufficient to provide for the permanent protection of
comparable farmland for the 1.2-acre conversion. The General Plan indicates mitigation fees
of comparable farmland at a ratio or 1:1, however the City's Development Code requires
mitigation fees at a ratio of up to 2:1 to be used for acquisition of a farmland conservation
easement of farmland deed restriction in accordance with Section 16.12.170. Proposed
mitigation fees are consistent with the 2: 1 ratio.

Setting. The San Luis Obispo County Air Pollution Control District (APCD) has developed the CEQA
Air Quality Handbook to evaluate project specific impacts and determine if air quality mitigation
measures are needed, or if potentially significant impacts could result. The City refers to this
Handbook for all discretionary projects subject to CEQA.
Impact. The proposed road extension allows for alternative circulation for existing development. Any·
future projects that may utilize the road extension will be evaluated under CEQA for any potential
impacts. The proposed road connection would be constructed along the periphery of existing parking
lots for Arroyo Grande High School and would not subject individuals to objectionable odors or expose
any sensitive receptors to substantial air pollutant concentrations.
Short-term impacts related to dust generation from grading would result in dust generation that could
affect adjacent properties. Mitigation measures placed on the project would reduce short-term dust
generation during construction of the project to less-than-significant levels. The dust control
measures listed below shall be followed during construction of the project, and shall be shown on
grading and building plans.

Mitigation/Conclusion. The following mitigation measures are necessary to reduce potential air
quality impacts from construction to a less-than-significant level. · · ·,,
The project shall comply with all applicable Air Pollution Control District (APCD) regulations
pertaining to the control of fugitive dust (PM 10) as contained in section 6.5 of the Air Quality
Handbook. All site grading and demolition plans shall list the following regulations:
MM 3.1: All dust control measures listed below (MM 3.2 -3.6) shall be followed during
construction of the project and shall be shown on grading and building plans. The contractor or
builder shall designate a person or persons to monitor the dust control program and to order
increased watering, as necessary, to prevent transport of dust off site. The name and telephone
number of such person(s) shall be provided to the APCD prior to map recordation and grading of
the road improvement and extension.
MM 3.2: During construction, water trucks or sprinkler systems shall be used to keep all
areas of vehicle movement damp enough to prevent airborne dust from leaving the site. At a
minimum. this would include wetting down such areas in the later morning and after work is
completed for the day and whenever wind exceeds 15 miles per hour. Reclaimed (non-potable)
water·should be used.
MM 3.3: Soil stockpiled for more than two days shall be covered, kept moist, or treated
with soil·binders to prevent dust generation.
MM 3.4: All vehicles hauling dirt, sand, soil, or other loose materials are to be covered or
should maintain at least twq feet of freeboard (minimum vertical distance -~etween top of load
and top of trailer) in accordance with eve Section 23114.
MM 3.5: Install wheel washers where vehicles enter and exit unpaved roads on to streets,
or wash off trucks and equipment leaving the site. Vehicle speed for all construction vehicles
shall not exceed 15 mph on any unpaved surface at the construction site.
MM 3.6: Sweep streets at the end of each day if visible soil material is carried on to
adjacent paved roads. Water sweepers with reclaimed water should be used where feasible.
MM 3.7: All off-road and portable diesel powered equipment, including but not limited to
bulldozers, graders, cranes, loaders, scrapers, backhoes, generator sets, compressors, auxiliary
power units, shall be fueled exclusively with California Air Resources Board (ARB) motor vehicle
diesel fuel.

Setting. The proposed road improvements and extension include an area of paved roadway that is
currently used for emergency access. The area· of land that will be included in the portion of the
roadway widening is currently roughly graded and includes an area used for storage containers. The
proposed roadway extension will traverse about 200 feet across a portion of the 1.2 acre agricultural
parcel currently in row crop production. There is a seasonal drainage ditch that traverses the AGHS
campus between sports fieJds and connects to the proposed 1.2-acre Public·· Facilities parcel.
However, the proposed _road construction will occur in the area where there is existing crop production
and avoids the area where there is some evidence of native vegetation (the drainage ditch is dug
seasonally in the crop area for flood protection.)
Impact. It is not anticipated that there will be any impact to biological resources due to the project
construction because the area of proposed construction does not include special habitat or important
vegetation. Any future development of the proposed 11.6-acre residential hillside parcel will be
subject to site-specific environmental review.

Setting. An assessment of archaeological/cultural resources in and surrounding the project area was
prepared by C.A. Singer and Associates, consulting archaeologists, under contract to McClelland
Consultants for the original Vista Del Mar subdivision planned development in 1990. The nearest
recorded archaeological site is located approximately 2,500 feet southwest of the project site near Los
Berros Creek. However, immediately south of the project site on the Haddox property, an unrecorded
site exists.
t:itv of Arrovo Grande, Initial Study for GPA06-001; DCA06-001; TPM 06-004 Page 9
Item 8.k. - Page 19
Impact. The assessment for the 1990 Vista Del Mar EIR included a surface examination _of the off-
site area that indicated that no part of the project site extends into the vicinity of the arch·aeological
site. Further, a thorough field reconnaissance of the project site revealed no surface evidence of the
prehistoric or early historic occupation or use of the site, and that the soils and geological conditions
of the site indicate that the likelihood of the project site is not anticipated to have any direct impact on
local archaeological/cultural resources.
Mitigation/Conclusion. Although it is not anticipated that there are any impacts to
archaeological/cultural resources, implementation of the mitigation measure(s) listed below will ensure
that no impacts will occur.
MM 5.1: In the event that prehistoric cultural materials, or historic cultural materials are
encountered, work in the immediate vicinity of the finds shall be suspended and a qualified
archaeologist and representative from the Northern Chumash Tribal Council allowed to quickly record,
collect, and analyze any resources encountered. The City shall be notified should resources meeting
CEQA significance standards be discovered. The Chumash representative and archaeologist shall
work as quickly as possible to permit resumption of construction activities. It is preferred that location
data of finds be recorded using a hand-held global positioning system (GPS) receiver. In the event
that human remains (burials) are found, the County Coroner (781-4513) shall be contacted immediately.
If the coroner determines that the remains are not subject to his or her authority and if the coroner
recognizes the remains to be those of a Native American, or has reason to believe that they are those
of a Native American, he or she will contact by telephone within 24 hours the Native American
Heritage Commission.

Setting. The site has varying topographical gradients with an approximate .2 -9% northwestern -
facing slope. There is a seasonal drainage ditch ·ttiat traverses the existing AGHS sports ·fields.
Undisturbed vegetation consists primarily of grasses. According to the 1990 EIR for Vista Del Mar,
the project area lies on a northwest -facing slope
Impact. A major source of potential earthquake damage to Arroyo Grande is from activity along the
regional San Andreas Fault located less than forty (40) miles east along the eastern border of San
Luis Obispo County. The most widespread intensity of ground shaking depends on several factors
including the magnitude of the earthquake, the distance from the earthquake epicenter, and
underlying soil conditions. Other regional faµlts of significance that could affect the project area in
terms of ground shaking are the Rincondada and Nacimiento faults, located approximately twenty-five
· •(25) miles east of the City. These faults are considered "potentially active", and could cause
moderate (Magnitude 6.0+) earthquakes in the area. The West Huasna fault is located roughly three
(3) miles east of the City of Arroyo Grande, The project site would be subject to severe ground
shaking in a strong seismic event,. which could cause damage to structures .and endanger public
safety ..
The project site will be subject to soil erosion and downstream sedimentation during construction and
after project completion. Specific erosion control requirements are specified below under the
Hydrology and Water Quality section.
Mitigation/Conclusion. Seismic hazard, soil stability, soil erosion and downstream sedimentation are
considered potentially significant impacts that can be reduced to a Jess-than-significant level with
implementation of the mitigation measures listed below.
MM 6.1: Final road improvement plans prepared by th~ City's consulting engineer shall be

originally anticipa~ed when the Vista del Mar subdivision was built as a preferred circulation alternative
instead of Orchard Ave. Castillo del Mar will enable access to a potential low density (maximum of 7-
units) subdivision on the proposed 11.6-acre residential hillside parcel.
Impact. The proposal addresses a . long-term circulation deficiency for AGHS and surrounding
residences. Although the project will enable access to a potential future subdivision, its potential for
increased traffic is less than ten peak-hour trips. and thus the road improvement is not considered to
induce substantial growth in the vicinity. The project will not· result in a need for a· significant amount

Setting. The project includes an improvement, extension and dedication of a portion of existing
emergency access road to improve public circulation around AGHS and to the existing dettelopment
of Vista del Mar and residential subdivision in the County. The proposed road connection will
implement a preferred circulation alternative (instead of Orchard Ave.) that was originally anticipated
when the Vista del Mar subdivision was built. Castillo del Mar will enable access to a potential low
density subdivision on the proposed 11.6-acre residential hillside parcel subject to future
environmental review.
Impact. Due to the grade change on the north shoulder of the existing emergency access portion of
Castillo del Mar, additional widening on the north side may require retaining walls. In order to reduce
the need for retaining walls to accommodate the 64' right-of-way. the following mitigation shall be
required. -Additionally, mitigation is required in order to provide for and encourage bicycle

Setting. Localized stormwater surface runoff follows the topography of the site nonherly toward
AGHS and farmland. A season drainage ditch traverses ·east to west the AGHS sports fields .and will
run through a proposed pipe under the proposed road extension near Valley Road and continue
through existing farmland to Los Berros Creek. Approximately one-acre of irrigated farmland will be
removed from production.
Impact. Construction and grading activities and exposed soil could cause erosion during prc;,ject
development. An approximate 150 ft. segment of proposed road extension will traverse the vicinity of
a drainage ditch, dug seasonally by the agricultural landowner for flood protection.
Mitigation/Conclusion. In order to reduce the potential for erosion and to provide for seasonal
· drainage, the following mitigation is required.
MM 14.1: To reduce ero?ion hazards due to construction activities, grading shall be
minimized, a!"]d the developer shall provide for a temporary siltation and drainage control basin
during construction. All finished slopes shall be t:iydroseeded with a ·permanent seed mix

Setting/Impact. Surrounding uses are identified on Page 3 of the Initial Study. The proposed project
was reviewed for consistency with policy and/or regulatory documents relating to the environment and
appropriate land use (e.g., City's Land Use Element, Development Code, Zoning Map, etc.).
Referrals were sent to outside agencies to review for policy consistencies and code compliance (e.g.
County Agricultural Commissioner, RWQCB, APCD.) As discussed in the section relating to impacts
to Agriculture, the proposed zoning and general plan land use designations for the 10-acre AGHS
sports fields and 11.6-acre proposed residential hillside parcel are considered internally consistent.
The General Plan land use designation and rezoning of the 1.2 acre of farmland requires mitigation.

Los Berros Creek and eventually to Arroyo Grande Creek. The proposal does not conflict with this
overlay by rezoning from agriculture to _public facility and the proposed road improvements and
extension will provide for the necessary drainage facility.
Mitigation/conclusion. No inconsistencies remain after implementation of all required mitigation and
no additional mitig~tion is determined to be necessary.
