MEMORANDUM
TO: PLANNING COMMISSION
FROM: CHRISTOPHER MAGDOSKU, PUBLIC WORKS DIRECTOR
SUBJECT: CONSIDERATION OF DRAFT INITIAL STUDY/MITIGATED NEGATIVE
DECLARATION FOR THE JAMES WAY OAK HABITAT AND WILDLIFE
PRESERVE TRAIL ADDITION
DATE: JULY 18, 2017
RECOMMENDATION:
It is recommended that the Planning Commission:
1. Review the Draft Initial Study/Mitigated Negative Declaration (IS/MND) for the
proposed James Way Oak Habitat and Wildlife Preserve Trail Addition; and
2. Make a recommendation to the City Council to adopt the MND, instruct the City
Clerk to file a Notice of Determination (NOD), and approve the trail design
improvements.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The cost to prepare the IS/MND, which includes field surveys and a future
preconstruction meeting, is $3,400. This expenditure is to be funded out of the Public
Works Administration-Contractual Services account from the approved Public Works
Department budget for FY 2017-18. Approximately twenty (20) hours of staff resources
were required to prepare documents, review the draft IS/MND, and prepare reports
related to this proposed project.
BACKGROUND:
On January 11, 2017, the Parks and Recreation Commission voted unanimously to
bring back for formal consideration a proposal to construct an additional hiking trail
segment in the James Way Oak Habitat and Wildlife Preserve (the “Preserve”) called
the James Way Oak Habitat and Wildlife Preserve Trail Addition (the “Project”).
On April 12, 2017, the Parks and Recreation Commission recommended approval of the
proposed project to the City Council. Ms. Cindy Cleveland, a biologist under contract
with the City, made a presentation on the Project including a drone fly-over of the
walking path. Ms. Cleveland also prepared a Technical Memorandum on the Project
which was attached to the agenda report.

PROJECT LOCATION:
ANALYSIS OF ISSUES:
Project Description
The Preserve property, circled in red in the aerial photograph above, is made up of two
separate lots, totaling 75.02 acres of open space. The property is zoned Planned
Development 1.2 (PD 1.2) with a Conservation/Open Space land use designation.
Current improvements to the property include a functioning windmill, solid waste
receptacles, drainage facilities and ponds, a pedestrian bridge, split-rail fencing and
approximately two (2) miles of hiking and walking paths. The City of Arroyo Grande is
the property owner and maintenance is shared and augmented by staff from th e Public
Works Department and volunteers.
The proposed Project will extend the existing trail by approximately 3/4 mile. The
proposed trail will be built by volunteers that have experience in both trail construction
and trail maintenance. Trail construction is expected to occur over eight (8) weeks
depending on volunteer resources and wea ther conditions. The new trail will be
constructed with hand tools and the natural appearance of the trail corridor will be
maintained. The new trail will remove vegetation and soil as needed to create a
walkable surface. Soil will be removed from inside of the trail to the outside of the trail
and compacted in place.
General Plan
The General Plan designates the subject Preserve property as Planned Development
with a Conservation/Open Space land use designation. The Project is consistent with
the following objectives of the City’s Conservation and Open Space (C/OS) and Parks
and Recreation (PR) Elements of the General Plan:
C/OS3: Plan for a well-maintained system of footpaths and non-vehicular trails
that provide access to areas of non-urban environment.

PR4: A network of recreational trails, bicycle lanes and bikeways should be
established for use by local residents and visitors to the Arroyo Grande Valley.
Open-Space Agreement
The underlying Open-Space Agreement granting an open-space easement to the City
of Arroyo Grande (Document No. 1994-027874, as official records of San Luis Obispo
County) contains language restricting certain uses of the subject pro perty. The
document provides exceptions for City-approved trails and stipulates that the “general
topography of the landscape shall be maintained in its present conditions and no
grading, grazing, excavation, or topographic changes shall be made except by the joint
approval of owner and City”; however, it precludes and makes exceptions for the
construction of public pathways. As such, the proposed trail expansion is consistent and
compatible with the underlying agreement.
It should be noted, subsequently to the acceptance of the Agreement , that the current
landowner is the City as it was transferred to the City when the City Council adopted
Resolution No. 3052 on September 13, 1994. (The previous owner, Ottse, Inc.,
developed the tract adjacent to the open -space when the Agreement was prepared and
accepted on April 26, 1994).
IS/MND
The draft IS/MND identifies biological resources and cultural resources as
environmental factors that could be potentially affected by the Project. These issues are
briefly discussed below and an excerpt of the mitigation measures from the draft
document is also provided.
Biological Resources
As discussed in the IS/MND, the project site contains numerous vegetation species
including Coast Live Oak, California Annual and Perennial Grassland, and California
Sage Brush habitats which may contain special status plant and animal species. Within
this variety of native habitats, nonnative grasses are interwoven throughout the Project.
The IS/MND indicates that there will be no impacts to riparian habitat, federally
impacted wetlands, or conflict with provisions of an adopted Habitat Conservation Plan,
Natural Community Conservation Plan, or other approved local, regional, or state
habitat conservation plan. However, there are less than significant impacts with
mitigation related to habitat modification on sensitive species, movement of wildlife
species, and potential conflict with the City’s Community Tree Program (Coast Live oak
trees are a protected species within Chapter 12.16 of the Municipal Code). Five (5)
mitigation measures contained in the document mitigate these impacts to less than
significant:

MM IV-1
A qualified biologist shall perform a special-status plant survey in the Project area
before any work activities begin. All project activities shall avoid any special-status plant
species that are found during the preconstruction survey. Before any Project activities
commence, all trail workers shall attend biological orientation training, provided by a
qualified biologist that covers the avoidance of any special-status plant species.
MM IV-2
The Project site shall be surveyed before construction for Wells’ Manzanita. If any
Wells’ Manzanita are found within the Project site, the plants will be avoided. Before any
Project activities commence, all trail workers shall attend biological orientation training,
provided by a qualified biologist that covers the avoidance of Wells’ Manzanita.
MM IV-3
Prior to any Project activities, a qualified biologist shall survey disturbance areas and
relocate any silvery legless lizards and/or coast horned lizards found, to a safe area
outside of the Project area. Surveys shall include raking of leaf litter and s and where
habitats exist. A qualified biologist shall be present at all times during ground disturbing
Project activities to recover any silvery legless lizards and coast horned lizards that may
be found. Before any Project activities commence, all trail workers shall attend
biological orientation training, provided by a qualified biologist that covers the avoidance
of any special-status animal species that may occur or that were found in the Project
area.
MM IV-4
If the Project is to be completed durin g the nesting bird season, which is typically
between the middle of February to the end of August, a nesting bird survey by a
qualified biologist shall be performed in the Project area before any work activities
commence. If any nesting birds are found, an appropriate and highly visible buffer shall
be established around the nest until the nest is no longer occupied. In addition, a
qualified biologist shall do a preconstruction survey for badgers and their dens and for
bats. If a badger den is located, a buffer shall be established around the den. If any bats
are located, consultation with the California Department of Fish and Wildlife shall be
initiated.
MM IV-5:
Where possible, project activities shall occur outside of 1.5 times the dripline for any oak
tree. In areas where this is not possible due the high density of oaks, project activities
will not expose any oak tree roots and only the minimum amount of vegeta tion needed
for trail construction shall be removed. Only hand tools shall be used for trail
construction. Before any Project activities commence, all trail workers shall attend
biological orientation training, provided by a qualified biologist, that cover s oak tree
avoidance, if possible, and oak tree mitigations.

Cultural Resources
The Chumash Indians lived in the region and many archaeological sites have been
identified within the City limits. Isolated archaeological materials could still be present
given the extensive history of Chumash Indians inhabiting this area. The IS/MND
indicates that there are no impacts to a historical resource, however there are less than
significant impacts with mitigation for archaeological and paleontological resources, and
possible disturbance of human remains outside of formal cemeteries. Should these
cultural resources be discovered during construction of the Project, work will stop to
allow a qualified archaeologist employed to view and assess the discovery and prepare
a mitigation plan. Two mitigation measures contained in the document mitigate these
impacts to less than significant:
MM V-1
If a potentially significant cultural resource is encountered during surface earthwork
activities, all construction activities within a 100-foot radius of the find shall cease until a
qualified archaeologist determines whether the uncovered resource requires further
study. Any previously undiscovered resources found during construction shall be
recorded on appropriate California Department of Parks and Recreation (DPR) forms
and evaluated for significance in terms of California Environmental Quality Act criteria
by a qualified archaeologist. Potentially significant cultural resources consist of, but are
not limited to, stone, bone, glass, ceramic, wood, or shell artifacts; fossils; or features
including hearths, structural remains, or historic dumpsites. If the resource is
determined significant under CEQA, the qualified archaeologist shall prepare and
implement a research design and archaeological data recovery plan that will capture
those categories of data for which the site is significant. The archaeologist shall also
perform appropriate technical analysis, prepare a comprehensive report, and file it with
the appropriate Information Center and provide for the permanent curation of the
recovered materials.
MM V-2
If human remains are encountered during earth -disturbing activities, all work in the
adjacent area shall stop immediately and the San Luis Obispo County Coroner’s office
shall be notified. If the remains are determined to be Native American in origin, the
Native American Heritage Commission shall be notified and will identify the Most Likely
Descendent, who will be consulted for recommendations for treatment of the discovered
remains.
ALTERNATIVES:
The following alternatives are provided for the Commission’s consideration:
1. Recommend that the City Council approve staff’s recommendations;
2. Do not recommend that the City Council approve staff’s recommendations and
request further information;

3. Modify staff’s recommendation and recommend approval to City Council; or
4. Provide direction to staff.
ADVANTAGES:
The James Way Open Space Preserve is an important community amenity that
provides a variety of purposes, including native habitat protection, and an opportunity
for recreational activities such as walking, mountain biking, hiking and wildlife viewing.
Adding additional trail opportunities enhances the Preserve and is consistent with the
City’s General Plan objectives.
DISADVANTAGES:
None identified.

Project Description:
The proposed project includes expanding an existing trail located within the James Way Oak Habitat and
Wildlife Preserve. The new 0.75 mile trial will connect to the existing trail and will be located upland
from sensitive riparian habitats. The new trail will allow trail access during winter months and will
protect wetland and riparian habitats and species. The proposed trail will be built by City of Arroyo
Grande trail volunteers who have experience with both trail construction and trail maintenance, and
with the assistance of the non-profit Central Coast Concerned Mountain Bikers organization. Trail
construction is expected to take 4-8 weeks depending on the number of volunteers and weather
conditions.
Summary Document Preparation:
Pursuant to Section 21082.1 of the California Environmental Quality Act, the City of Arroyo Grande (the
City) has independently reviewed and analyzed the Initial Study and Mitigated Negative Declaration for
the proposed project and finds that these documents reflect the independent judgment of the City. The
City, as lead agency, also confirms that the project mitigation measures detailed in these documents are
feasible and will be implemented as stated in the Mitigated Negative Declaration.

Introduction
Introduction and Regulatory Guidance
The Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared by the City of Arroyo
Grande (the City) to evaluate the potential environmental effects of the proposed project. This
document has been prepared in accordance with the California Environmental Quality Act (CEQA), Public
Resources Code §21000 et seq., and the State CEQA Guidelines, California Code of Regulations (CCR)
§15000 et seq.
An Initial Study is conducted by a lead agency to determine if a project may have a significant effect on
the environment [CEQA Guidelines §15063(a)]. If there is substantial evidence that a project may have a
significant effect on the environment, an Environmental Impact Report (EIR) must be prepared, in
accordance with CEQA Guidelines §15064(a). However, if the lead agency determines that revisions in
the project plans or proposals made by or agreed to by the applicant mitigate the potentially significant
effects to a less-than-significant level, a Mitigated Negative Declaration may be prepared instead of an
EIR [CEQA Guidelines §15070(b)]. The lead agency prepares a written statement describing the reasons
a proposed project would not have a significant effect on the environment and, therefore, why an EIR
need not be prepared. This IS/MND conforms to the content requirements under CEQA Guidelines
§15071.
Lead Agency
The lead agency is the public agency with primary approval authority over the proposed project. In
accordance with CEQA Guidelines §15051(b)(1), "the lead agency will normally be an agency with
general governmental powers, such as a city or county, rather than an agency with a single or limited
purpose." The lead agency for the proposed project is the City of Arroyo Grande. The contact person for
the lead agency is:

Purpose and Document Organization
The purpose of this document is to evaluate the potential environmental effects of the proposed
project. Mitigation measures have been identified and incorporated into the project to eliminate any
potentially significant impacts or reduce them to a less-than-significant level.
This document is organized as follows:

This chapter describes the reasons for the project, scope of the project, and project objectives.
Environmental Setting, Potential Impacts and Mitigation Measures
This chapter identifies the significance of potential environmental impacts, explains the
environmental setting for each environmental issue, and evaluates the potential impacts
identified in the CEQA Environmental (Initial Study) Checklist. Mitigation measures are
incorporated, where appropriate, to reduce potentially significant impacts to a less-than-
significant level.
Mandatory Findings of Significance
This chapter identifies and summarizes the overall significance of any potential impacts to
natural and cultural resources, cumulative impacts, and impact to humans, as identified in the
Initial Study.
Summary of Mitigation Measures
This chapter summarizes the mitigation measures incorporated into the project as a result of the
Initial Study.
References
This chapter identifies the references and sources used in the preparation of this IS/MND. It also
provides a list of those involved in the preparation of this document.
Summary of Findings
Section 3 of this document contains the Environmental (Initial Study) Checklist that identifies the
potential environmental impacts (by environmental issue) and a brief discussion of each impact resulting
from implementation of the proposed project.
In accordance with §15064(f) of the CEQA Guidelines, a Mitigated Negative Declaration shall be
prepared if the proposed project will not have a significant effect on the environment after the inclusion
of mitigation measures in the project. Based on the available project information and the
environmental analysis presented in this document, there is no substantial evidence that, after the
incorporation of mitigation measures, the proposed project would have a significant effect on the
environment. It is proposed that a Mitigated Negative Declaration be adopted in accordance with the
CEQA Guidelines.
Revisions
None.

Project Description
Introduction
This Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared by the City of Arroyo
Grande (the City) to evaluate the potential environmental effects of the proposed project. The project
site is located in the approximately 60-acre James Way Oak Habitat and Wildlife Preserve (Preserve).
Location
The project site is bounded on the north by James Way, to the east by residential development and to
the south and west by a combination of residential and commercial development.
Background and Need for Project
The project site is located within James Way Oak Habitat and Wildlife Preserve. The James Way Oak
Habitat and Wildlife Preserve was established as mitigation for an adjacent housing development.
In order to improve trails with the James Way Oak Habitat and Wildlife Preserve, a 0.75 mile trail addition
will be built upland from an existing trail. The new trail will allow the existing trail to be expanded into a
loop, will add an additional 0.75 of a mile to the trail system, and will allow trail access during the winter
months when the established trail often becomes flooded and impassable. In addition, the new trail will
move hikers into less sensitive habitat areas and away from wetland habitats where the existing trail is
located.
Project Description
The proposed trail expansion will be built by City of Arroyo Grande trail volunteers who have experience
with both trail construction and trail maintenance, and with the assistance of Central Coast Concerned
Mountain Bikers organization. The trail workers will either hike or bike into the Project site and will use
only hand tools for all trail construction activities. All work activities will be done with the minimal
amount of impact needed for trail construction and all work tools will be removed from the project site
after each day of construction.
Emphasis will be on maintaining the natural appearance of the trail corridor. The new trail cut will
remove vegetation and soil which will then be saved (to disperse on the trail once it is completed to
make it look aged) or carried off-site for disposal. Once the trail is cleared, soil will be removed from the
inside of the trail to the outside of the trail and packed into place (1/2 bench cut). Trail construction is
expected to take 4-8 weeks depending on the number of volunteers and weather conditions.
Required Public Agency Approvals
No other public agency approvals are required for the proposed project.

Mandatory Findings of Significance
INITIAL STUDY MITIGATED NEGATIVE DECLARATION June 2017
JAMES WAY OAK HABITAT & WILDLIFE PRESERVE TRAIL ADDITION
Page 9 of 31
Determination
On the basis of this initial evaluation:
I find that the proposed project COULD NOT have a significant effect on the environment and a
NEGATIVE DECLARATION will be prepared.
I find that, although the original scope of the proposed project COULD have had a significant
effect on the environment, there WILL NOT be a significant effect because revisions/mitigations
to the project have been made by or agreed to by the applicant. A MITIGATED NEGATIVE
DECLARATION will be prepared.
I find that the proposed project MAY have a significant effect on the environment and an
ENVIRONMENTAL IMPACT REPORT or its functional equivalent will be prepared.
I find that the proposed project MAY have a "potentially significant impact" or "potentially
significant unless mitigated impact" on the environment. However, at least one impact has
been adequately analyzed in an earlier document, pursuant to applicable legal standards, and
has been addressed by mitigation measures based on the earlier analysis, as described in the
report's attachments. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze
only the impacts not sufficiently addressed in previous documents.
I find that, although the proposed project could have had a significant effect on the
environment, because all potentially significant effects have been adequately analyzed in an
earlier EIR or Negative Declaration, pursuant to applicable standards, and have been avoided or
mitigated, pursuant to an earlier EIR, including revisions or mitigation measures that are
imposed upon the proposed project, all impacts have been avoided or mitigated to a less-than-
significant level and no further action is required.

Evaluation of Environmental Impacts
1. A brief explanation is required for all answers, except "No Impact", that are adequately
supported by the information sources cited. A "No Impact" answer is adequately supported if
the referenced information sources show that the impact does not apply to the project being
evaluated (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be
explained where it is based on general or project-specific factors (e.g., the project will not
expose sensitive receptors to pollutants, based on a project-specific screening analysis).
2. All answers must consider the whole of the project-related effects, both direct and indirect,
including off-site, cumulative, construction, and operational impacts.
3. Once the lead agency has determined that a particular physical impact may occur, the checklist
answers must indicate whether that impact is potentially significant, less than significant with
mitigation, or less than significant. "Potentially Significant Impact" is appropriate when there is
sufficient evidence that a substantial or potentially substantial adverse change may occur in any
of the physical conditions within the area affected by the project that cannot be mitigated
below a level of significance. If there are one or more "Potentially Significant Impact" entries, an
Environmental Impact Report (EIR) is required.
4. A "Mitigated Negative Declaration" (Negative Declaration: Less Than Significant with Mitigation
Incorporated) applies where the incorporation of mitigation measures, prior to declaration of
project approval, has reduced an effect from "Potentially Significant Impact" to a "Less Than
Significant Impact with Mitigation." The lead agency must describe the mitigation measures and
briefly explain how they reduce the effect to a less than significant level.
5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA
process, an effect has been adequately analyzed in an earlier EIR (including a General Plan) or
Negative Declaration [CCR, Guidelines for the Implementation of CEQA, § 15063(c)(3)(D)].
References to an earlier analysis should:
a) Identify the earlier analysis and state where it is available for review.
b) Indicate which effects from the environmental checklist were adequately analyzed in the
earlier document, pursuant to applicable legal standards, and whether these effects were
adequately addressed by mitigation measures included in that analysis.
c) Describe the mitigation measures in this document that were incorporated or refined from
the earlier document and indicate to what extent they address site-specific conditions for
this project.
6. Lead agencies are encouraged to incorporate references to information sources for potential
impacts into the checklist or appendix (e.g., general plans, zoning ordinances, biological
assessments). Reference to a previously prepared or outside document should include an
indication of the page or pages where the statement is substantiated.
7. A source list should be appended to this document. Sources used or individuals contacted
should be listed in the source list and cited in the discussion.
8. Explanation(s) of each issue should identify:
a) the criteria or threshold, if any, used to evaluate the significance of the impact addressed by
each question and
b) the mitigation measures, if any, prescribed to reduce the impact below the level of
significance.

Environmental Issues
I. Aesthetics
Environmental Setting
The project site is located entirely within the James Way Oak Habitat and Wildlife Preserve which
provides open space for pedestrian recreational uses and habitats for plant and animal species. The
project site is within Coast Live Oak, California Annual and Perennial Grassland and California Sage Brush
habitats. There are no anthropomorphic impacts on the project site except for the existing Preserve
trail.
The project site is located on a northern facing hill and is not visible from any roadways and would not
alter any scenic vistas or scenic resources.
Would the project:
Potentially
Significant
Impact
Less Than

No Impact
a) Have a substantial adverse effect on a scenic vista?
b) Substantially damage scenic resources, including,
but not limited to, trees, rock outcroppings, and
historic buildings within a state scenic highway?
c) Substantially degrade the existing visual character or
quality of the site and its surroundings?
d) Create a new source of substantial light or glare
which would adversely affect day or nighttime views in
the area?
Discussion
a-d: No impact.
No impacts would occur, therefore, no mitigation is required.
II. Agriculture and Forestry Resources
Environmental Setting
The project site is not designated or zoned for agriculture use, has not been used for agricultural
production and is not near to land zoned agriculture. The site does not contain prime soils according to
the California Department of Conservation’s Important Farmland Map of San Luis Obispo County.

a) Convert Prime Farmland, Unique Farmland, or
Farmland of Statewide Importance (Farmland), as
shown on the maps prepared pursuant to the
Farmland Mapping and Monitoring Program of the
California Resources Agency, to non-agricultural use?
b) Conflict with existing zoning for agricultural use or a
Williamson Act contract?
c) Conflict with existing zoning for, or cause rezoning
of, forest land (as defined in Public Resources Code
section 12220)g)), timberland (as defined by Public
Resources Code section 4526), or timberland zoned
Timberland Production (as defined by Government
Code section 51104(g))?
d) Result in the loss of forest land or conversion of
forest land to non-forest use?
e) Involve other changes in the existing environment
which, due to their location or nature, could result in

III. Air Quality
Environmental Setting
Existing conditions for air quality in the City of Arroyo Grande are described in detail in the County’s
2001 Clean Air Plan which is incorporated herein by reference. The Clean Air Plan is a comprehensive
planning document designed to reduce emissions from traditional industrial and commercial sources, as
well as from motor vehicle use. The purpose of the County’s Clean Air Plan is to address the attainment
and maintenance of state and federal ambient air quality standards by following a comprehensive set of
emission control measures within the Plan. Based on information available, it is not expected that
baseline conditions have changed significantly since the 2001 plan was completed.
San Luis Obispo County is in non-attainment status for ozone (O3), respirable particulate matter (PM10)
and vinyl chloride under the California Air Resource Board (CARB) standards. The County is in
attainment status for all other applicable CARB standards. The proposed project will not result in any
impacts to air quality.

violation?
c) Result in a cumulatively considerable net increase of
any criteria pollutant for which the project region is in
non-attainment under an applicable federal or state
ambient air quality standard (including releasing
emissions which exceed quantitative thresholds for
ozone precursors)?
d) Expose sensitive receptors to substantial pollutant
concentrations?
e) Create objectionable odors affecting a substantial
number of people?
* Where available, the significance criteria established by the applicable air quality management or air pollution control di strict
may be relied on to make these determinations.
Discussion
a-e: No impacts.
No impacts would occur, therefore, no mitigation is required.

MM V-1: If a potentially significant cultural resource is encountered during surface earthwork
activities, all construction activities within a 100-foot radius of the find shall cease until a
qualified archaeologist determines whether the uncovered resource requires further study. Any
previously undiscovered resources found during construction shall be recorded on appropriate
California Department of Parks and Recreation (DPR) forms and evaluated for significance in
terms of California Environmental Quality Act criteria by a qualified archaeologist. Potentially
significant cultural resources consist of, but are not limited to, stone, bone, glass, ceramic,
wood, or shell artifacts; fossils; or features including hearths, structural remains, or historic
dumpsites. If the resource is determined significant under CEQA, the qualified archaeologist
shall prepare and implement a research design and archaeological data recovery plan that will
capture those categories of data for which the site is significant. The archaeologist shall also
perform appropriate technical analysis, prepare a comprehensive report, and file it with the
appropriate Information Center and provide for the permanent curation of the recovered
materials.
MM V-2: If human remains are encountered during earth-disturbing activities, all work in the
adjacent area shall stop immediately and the San Luis Obispo County Coroner’s office shall be
notified. If the remains are determined to be Native American in origin, the Native American
Heritage Commission shall be notified and will identify the Most Likely Descendent, who will be
consulted for recommendations for treatment of the discovered remains.

incremental effects of an individual project are
significant when viewed in connection with the effects
of past projects, the effects of other current projects,
and the effects of possible future projects.
d) Cause substantial adverse effects on human beings,
either directly or indirectly?
Discussion
a: The project site contains special status plants and animals that may be impacted from project
construction. Isolated prehistoric materials may be present on the project site; however, the site does
not serve as an example of a major period of California history or prehistory.
b: There are no short-term environmental goals, either in the project description or the identified
mitigation measures that will be achieved to the disadvantage of long-term environmental goals.
c: With implementation of the proposed mitigation measures, the proposed project will not result in
any cumulatively considerable environmental impacts.
d: With implementation of the proposed mitigation measures, the proposed project will not cause
substantial adverse effects on human beings, either directly or indirectly.

between the middle of February to the end of August, a nesting bird survey by a qualified
biologist shall be performed in the Project area before any work activities commence. If any
nesting birds are found an appropriate and highly visible buffer shall be established around the
nest until the nest is no longer occupied. In addition, a qualified biologist shall do a
preconstruction survey for badgers and their dens and for bats. If a badger den is located a
buffer shall be established around the den. If any bats are located consultation with the
California Department of Fish and Wildlife shall be initiated.

MM IV-5: Where possible, project activities shall occur outside of 1.5 times the dripline for any
oak tree. In areas where this is not possible due the high density of oaks, project activities will
not expose any oak tree roots and only the minimum amount of vegetation needed for trail
construction shall be removed. Only hand tools shall be used for trail construction. Before any
Project activities commence, all trail workers shall attend biological orientation training,
provided by a qualified biologist, that covers oak tree avoidance, if possible, and oak tree
mitigations.

MM V-1: If a potentially significant cultural resource is encountered during subsurface
earthwork activities, all construction activities within a 100-foot radius of the find shall cease
until a qualified archaeologist determines whether the uncovered resource requires further
study. Any previously undiscovered resources found during construction shall be recorded on
appropriate California Department of Parks and Recreation (DPR) forms and evaluated for
significance in terms of California Environmental Quality Act criteria by a qualified archaeologist.
Potentially significant cultural resources consist of, but are not limited to, stone, bone, glass,
ceramic, wood, or shell artifacts; fossils; or features including hearths, structural remains, or
historic dumpsites. If the resource is determined significant under CEQA, the qualified
archaeologist shall prepare and implement a research design and archaeological data recovery
plan that will capture those categories of data for which the site is significant. The archaeologist
shall also perform appropriate technical analysis, prepare a comprehensive report, and file it
with the appropriate Information Center and provide for the permanent curation of the
recovered materials.
