DATE: September 26, 2000
SUBJECT: ADDENDUM TO HUNTERS GREEN (PROJECT NOW KNOWN AS
ROBINSON RANCH) FINAL ENVIRONMENTAL IMPACT REPORT
(FEIR) FOR ROBINSON RANCH TRAIL IN ANGELES NATIONAL
FOREST(ANF)
DEPARTMENT: Planning and Building Services
RECOMMENDED ACTION
Adopt resolution and approve the addendum to the FEIR for the Hunters Green (project now known
as Robinson Ranch) Residential Development and Golf Course.
This addendum results from a federal environmental review pursuant to the National Environmental
Protection Act where an environmental assessment document was completed analyzing the
environmental effects of the portions of the Robinson Ranch Trail proposed to be located in the
Angeles National Forest (ANF). On July 31, 2000, the District Ranger of the ANIT issued a Decision
Notice and a Finding of No Significant Impact (FONSI) related to the new trail design and
alignment.
The addendum evaluates details of the multi -use trail component of the project for which details
were unknown at the time of FEIR certification. The proposed trail was intended to provide access
to the regional trail network in the adjacent ANF. Trail planning efforts have led to changes to the
trail alignment, and now result in a corridor that would be partially developed on federal property
administered by the United States Forest Service.
The original proposed project required and obtained approval for the City of Santa Clarita as the lead
agency in September 1, 1996. Since that time the project applicant has modified the development
plan by adjusting the course of the north -south trail along its eastern border resulting in .43 miles of
trail crossing into federal lands administered by the ANF.

ROBINSON RANCH TRAIL
DECISION NOTICE AND
FINDING OF NO SIGNIFICANT IMPACTS
U.S.D.A. FOREST SERVICE
ANGELES NATIONAL FOREST
Santa Clara/Mojave Rivers Ranger District
Los Angeles County, California
Robinson Ranch Development Services has proposed that portions of the Robinson Ranch Trail
be constructed on the Angeles National Forest (ANF), located in portions of T4N, R14W,
Sections 19 & 30; and portions of T4N, R15W, Sections 24 & 25. This is identified as
Alternative I — Proposed Project in the Environmental Assessment (EA) of June 2000. The
multifunctional equestrian/hike/bike trail will have an overall length of approximately 1. 16 miles
long with approximately 0.43 miles on National Forest land. The trail will be located along the
eastern edge of the Robinson Ranch Golf Course and situated in a North-South direction.
Maintenance of the trail will be the responsibility of the City of Santa Clarita (City) with
maintenance of that portion of trail on the national forest authorized under a special use permit.
'The trail will have:
• An overall clearance width of 10 feet.
• An eight foot tread,
• A 3 -rail lodgepole fence will be constructed along the trail on the Ranch properties. The
fence will be constructed on the national forest on the down hill side of the trail where the
slope is greater than 25% for safety purposes.
• A trail surface of uncompacted native soil.
• One viewing area and one rest area.
Constructing a portion of the trail on the ANF is key to keeping the maximum slope to 15% for
no more than 300 feet.
The edge of the trail will be revegetated with native vegetation approved by the Forest Servic'e.
Alternative 2 — No Involvement On Federal Lands, and Alternative 3 — No Action Alternative,
would essentially have the same results regarding impacts to national forest land. However,
should Robinson Ranch properties implement Alternative 2, trail slopes would exceed 25% and
more ground disturbance would occur. Under Alternative 3, there would be no new public
recreation trail in this area.
The ANF is the lead agency, with the City as a cooperating agency, to analyze the Proposed
Action the No Action and the No Involvement Of Federal Lands Alternatives for Robinson
Ranch Development Services, as described in detail in the attached Environmental Assessment
(EA).
Request for input was published in local newspapers in addition to publication in the Angeles
National Forest Environmental Documents Under Preparation newsletter. As part of their
overall planning, the City of Santa Clarita also made contacts with adjacent landowners and
forest users. The ANF also conducted an informational and scoping meeting with the City and
members of the Sand Canyon Trails Committee. No comments were received during the
comment period that objected to this proposal.
The determination of the affects of the 3 alternatives was based on consultation and coordination
with the City, Robinson Ranch, forest and contracted specialists, as well as the professional
judgment and experience of the EA preparers. A listing of participating agencies, preparers and
references are found in Section 4.0 of the EA.
Decision
Based on the review of the Final EA for the Robinson Ranch Trail, it is my decision to allow the
construction of approximately 0.43miles of trail on the Angeles National Forest and to
incorporate the mitigation measures and recommendations outlined in the EA.
Finding of No Significant Impact: Based analysis of the potential environmental impacts
contained in the EA, I have determmied that the impacts with the construction and maintenance
of 0.43 miles of traiton the Angeles National Forest arc not expected to be significant, that the
proposal does not constitute a major federal action, and the preparation of an environmental
impact statement pursuant to Section 102(2)0 of the National Environmental Policy Act of 1969
is, therefore, not appropriate.
Rational for the Finding:
• The impacts identified through the EA were local, generally minor and readily mitigated.
• There are no known or anticipated negative effects on floodplains, parklands, prime
farmland, wetlands, wild and scenic rivers, or ecologically critical areas.
• There would be no adverse effects on land use, planning recreation and socioeconomics.
• There would b e no loss or destruction of significant scientific, cultural, historic or
paleontological resources.
• The proposal is not controversial.
• The proposal would not impose unknown risks on the human environment, and there are
no adverse effects on public health and safety.
• There are no known irreversible or irretrievable impacts.
• The project will not affect any threatened and endangered species.
• The proposed action.is designed to be consistent with other laws and regulation (e.g. City
planning requirements, oak tree management, etc.)
• Robinson Ranch will construct the trail system and maintenance will be the responsibility
of the City of Santa Clarita.
Findin2s Required by Other Laws
The proposal is consistent with the management direction in the Angeles National Forest Land
and Resource Management Plan, 1977 (LMP), pages 4-4, 4-13, 4-43, and Management
Prescription #3.
Implementation
Pursuant to 36CFR215.8(3), Decision not subject to appeals; 36CFR215.9; Notice of Decision;
and 36CFR215, Implementation of decisions; this project may proceed one day after notification
of this decision to the public. I

Addendum Ito FEIR
ADDENDUM
August 2000
This document is an Addendum to the Final Environmental Irnpact Report (FEIR) for the
Hunters Green Residential Development and Golf Course (September 1, 1996, State
Clearinghouse Number 95041049). It evaluates details of the multi -use trail component of the
project for which details where unknown at the time of FEIR certification. The proposed trail
was intended to provide access to the regional trail network in the adjacent Angeles National
Forest. Trail planning efforts have led to changes to the trail alignment, and now result in a
corridor that would be partially developed on federal property administered by the U.S. Forest
Service. Therefore, federal environmental review pursuant to the National Environmental
Protection Act (NEPA) requirements was required. An Environmental Assessment document
was published in June 2000 analyzing the environmental effects of the precise trail alignment
and design. On July 31, 2000, the District Ranger issued a Decision Notice and Finding of No
Significant Impact (FONSI) related to the new trail design and alignment. This information
was unavailable at the time of the 1996 certification of the FEIR, and this addendum serves to
update the 1996 FEIR.
A-1. Project History
The original proposed project required approval from the City of Santa Clarita as the lead agency.
It also required related actions by responsible agencies, including the Los Angeles County Local
Agency Formation Commission (LAFCO), Los Angeles County Sanitation Districts, and the
Califon -da Department of Fish and Game. The project was therefore subject to the requirements of
CEQA (Public Resources Code, Section 21000, et. seq.). In accordance with the provisions of the
State CEQA Guidelines, the City of Santa Clarita Community Development Department prepared
an Initial Study. The Initial Study, now contained in the Final EIR as Appendix A, determined
that the proposed project could result in significant adverse effects on the environment, and that
an EIR was required for the project.
In accordance with Section 15121 (a) of the State CEQA Guidelines (California Administrative
Code, Title 14, Division 6, Chapter 3), the purpose of an EIR is to serve as an informational
document that:
... Mil inform public agency decision -makers and the public generally of the signftant
environmental effect of a project, ident#� possible ways to minimize the significant effects,
and describe reasonable alternatives to the project...
On September 1, 1996, the Hunters Green Residential and Development Goff Course Final EIR
was completed and subsequently certified for a combined residential/golf course project at the
subject site. The project analyzed in the Final EIR included a total of 76 residential units,
clubhouse, driving range, parking lot, two eighteen -hole golf courses, and a recreational trail
that would border the site along its eastern edge. Since that time, the project applicant has
modified the development plan by adjusting the course of this north -south trail resulting in
approximately 0.43 miles crossing into federal lands administered by the Angeles National Forest.

Hunters Green Residential Development and Golf Course
Addendum to FEIR
A-2. Addendum Scope and Content
The following issues have been identified for analysis in this Addendum to the Final EIR for the
Hunters Green Residential and Development Golf Course, relative to the new information
available for the trail component:
Biological Resources
Cultural Resources
All other sections of the Final EIR for the Hunters Green Residential and Development Golf
Course have been determined to accurately represent the changes and potential effects of the
revised project, and have mitigated for potential impacts should they occur. Taken together,
this Addendum and the Final EIR are intended to meet the environmental analysis
requirements of CEQA.
A-3. Summary of Changes Hereby Added to the 1996 Final EIR
This Addendum summarizes information that is presented in the Robinson Ranch Trail Final
Environmental Assessment (U.S. Forest Service, June 2000), and incorporates it by reference.
The additional information available related to the recreational trail relates to its design features
and its precise alignment. These features dictate the grading and construction activity levels,
details were unknown at the time of the preparation of the 1996 Final EIR.
Primary areas of additional inquiry included biological resources and cultural resources. In both
of these environmental issue areas, additional assessments were conducted for the trail corridor.
The proposed revisions to the Robinson Ranch trail should not result in any additional significant
impacts that are not either already covered in the FEIR or that would be reduced by the proposed
mitigation included in the June 2000 Environmental Assessment, which is summarized below.
Biological Resources. The proposed trail would result in a temporary disturbance to
2.2 acres which includes a permanent commitment of 1.7 acres to trail use. Included in these
amounts is 0.7 acre that is an existing dirt road with no biological value, therefore, vegetation
loss is limited to 1.5 acres and permanent vegetation loss would occur on 1.0 acre. Vegetation
habitat loss within the Forest includes a temporary loss of 1 -acre and a permanent loss of 0.5
acres of chaparral and 0.1 acres of Alluvial Fan Scrub. Alteration of 1 acre of chaparral
vegetation as a result of trail construction is not considered a significant impact. Additionally,
mitigation is included to revegetate areas temporarily disturbed with the shrub -scrub n-dx of
species that exist within the project area.
The 0.43 mile extension of the 8' trail would result in the removal of an additional 0.43 acres of
alluvial fan scrub and any sensitive species residing there. At least two oak trees will also be
affected within 5' of their dripline (Rincon, 2000). Nfitigation for these impacts is outlined
within the Hunters Green Residential Development and Golf Course FOR (Rincon, 1996) and
will be applied to the proposed trafl. No significant impact is expected after mitigation.
Direct impacts to common wildlife species resulting from trail construction activities include
displacement and direct mortality. Trail construction would remove vegetation within a 1.16 -
mile long corridor with a maintained width of 12 feet which would extend to 13 feet next to
mining operations. Given the limited disturbance and permanent loss of vegetation (only 1
A-2
Hunters Green Residential Development and Goff Course
Addendum to FEIR
acre total), the loss of occupied habitat and displacement of common wildlife species from
construction activities is not considered a significant adverse impact.
Little direct mortality is anticipated from construction equipment crushing small mammals,
amphibians and reptiles since the small width of the construction area would allow for most
organisms to escape into adjacent habitat. Given the limited amount of habitat proposed for
removal, minimal impact would occur to local wildlife populations and no significant effects
are anticipated.
Potential indirect impacts to locally common and abundant wildlife are not considered
significant since drainage crossings will be minin-dzed, and all drainages will be crossed at right
angles (as per Forest Plan Standards and Guidelines). Signage would be required to be placed
at drainage crossings to discourage trespass within the drainage, as discussed in the mitigation
section below.
The project site does not support listed or proposed, threatened or endangered plant or wildlife
species.
Vege-ta Impacts to state endangered California orcutt grass and the federal
proposed threatened prostrate navarretia are not expected as the appropriate vernal pool
habitat does not exist within the proposed project site. No plants of the Berberis genus were
observed within the project area, and the endangered slender -homed spineflower is not
expected to be present, therefore, no impacts to the species are likely to occur (Rincon
Consultants, 1996).
Wildlife. No sensitive species are known to occur within the project site or were
observed during site visits. The Forest Sensitive Santa Ana sucker (Rick Ferris, January 2000),
the federal and state endangered and Forest Sensitive unarmored three -spine stickleback and
the federal endangered and Forest Sensitive arroyo toad are not expected to inhabit the
unnamed drainage area in Oak Springs Canyon due to lack of appropriate onsite habitat The
federal and state endangered and Forest Sensitive least Bell's vireo and the federally threatened
and forest service sensitive California gnatcatcher, the latter which is only seen near the
proposed project site as transitory migrants (Hovore, January 2000), are in the same situation.
Therefore, no onsite impacts to these species are expected with the proposed project
development (Rincon Consultants, 1996).
Approximately 0.2 acres of CDFG sensitive Alluvial Fan Scrub would be permanently lost due
to trail development, including 0. 1 acres on USFS land. The loss or disturbance of sensitive
Alluvial Fan Scrub from trail development was analyzed in the Hunters Green Residential
Development and Goff Course EIR (Rincon Consultants, 1996) and by the CDFG. Through
conditions of a Strearnbed Alteration agreement between the Robinson Ranch Goff Course and
the CDFG, 12 acres of replacement mitigation for impacts due to the loss or disturbance of the
Alluvial Fan Scrub habitat is being performed on the golf course property. The original
alignment of the trail, located entirely within the Golf Course, removed or impactedinore
Alluvial Fan Scrub than the currently proposed trail alignment. Therefore, potential impacts to
sensitive Alluvial Fan Scrub are not considered significant as replacement mitigation is
currently being performed for an amount in excess of what was anticipated to be lost.
A-3
Hunters Green Residential Development and Goff Course
Addendum to FEIR
The proposed trail alignment was specifically designed to avoid removing coast live oak trees
in the project area; however it appears as though the trail alignment will encroach into the
protected zones of at least two trees on Robinson Ranch property.
Resource protection measures, including replacement mitigation, have been incorporated into
the Hunters Green Residential Development and Golf Course EIR (Rincon, 1996). Mitigation
for Alluvial Fan Scrub is currently in progress. The following three measures were
incorporated into the Robinson Ranch Trail Final Environmental Assessment (U.S. Forest
Service, June 2000), and are intended to address potential impacts to vegetation and wildlife:
B10-1 Cut banks along the edge of the trail shall be covered with a seed mixture native to
the area to promote natural regeneration of plant species. The Robinson Ranch
Golf Course shall submit a copy of the revegetation and mitigation monitoring
plan, including the seed n-dx, to the USFS for review and approval. A biologist
familiar with restoration and mitigation techniques shall design the plan.
Restoration and mitigation shall be with locally occurring native species at a ratio
of 1:1 for the Chaparral and Riversidean Sage Scrub habitat. The plan shall
include, but not be lin-dted to the following components as outlined by the USFS:
1) Performance criteria (i.e.: what is an acceptable success level of revegetation to mitigate
past impacts);
2) Monitoring effort (who is to check on the success of the revegetation plan, how
ftequently);
3) Contingency planning (if the effortfails to reach the performance criteria, what
remediation steps need to be taken);
4) Irrigation method Ischedulefor wetland elements (how much water is needed where and
for how long); and
5) Provisionsfor the removal of non-native invasive species (including details regarding
the type and use of herbicides in and near aquatic habitat and sensitive species).
B10-3 A wildlife biologist or other trained resource personnel shall be on site within U.S.
Forest Service property while construction activities are in progress. The biologist
or trained personnel shall search the trail construction area for sensitive wildlife
species, specifically the sensitive San Diego homed lizard, two -stripe garter and
San Bernardino ring-necked snake, and if necessary, relocate individuals to
suitable habitat in the vicinity.
Cultural Resources. No archeological or other historic resources are known to be
within the project area from either records or field surveys (city of Santa Clarita September,
1995). Since by its nature, an archaeological reconnaissance can only confidently assess the
potential for encountering surface cultural resource remains, customary caution is advised in
development activities within the project area. As outlined in the initial study, in the event that
any cultural resources are found, a "hold" shall be paced on the project until a trained
archeologist has inspected the site. In addition the archeologist shall determine the nature of
the resource and take the appropriate actions, as defined under the new 1998 CEQA revisions.
Specifically:
A-4
Hunters Green Residential Development and Golf Course
Addendum to FEIR
In the event that archaeological resources or human remains are unearthed during project
construction or maintenance activities in thefuel modification zone in either of the
acquisition areas, all earth -disturbing work within the vicinity of thefind shall be
temporarily suspended or redirected until an archaeologist has evaluated the nature and
significance of thefind. If thefind is determined to be an historical or "unique"
archaeological resource as defined in the Public Resources Code, Division 13, Sections
15406.5(a) and 21083.2, then contingencyfunding and a time allotment sufficientfor
appropriate avoidance or mitigation shall be made available. Whenfeasible, impacts shall be
avoided through preservation of the site. This can include:
• Planning construction to miss the site;
• Incorporating sites within parks, greenspace, or other open space;
• "Capping" or covering the site with a layer of chemically stable soil before building; or
• Deeding the site into a permanent conservation easement. (PRC 15126.4 (b)(3)(B))
The most appropriate measure shall be determined by the specific location and circumstances
surrounding the resource, and the potential impact of the action.
In the event that data recovery is the only feasible form of mitigation, scientifically important
materials and information shall be deposited in the California Historical Resources Regional
Information Center (CHRRIQ unless the lead agency determines that the scientifically
consequential information from and about the resource has already been documented in the
EIR and deposed at the CHRRIC. If human remains are found, If human remains are
unearthed, State Health and Safety Code Section 7050.5 requires that no hu-ther disturbance
shall occur until the County Coroner has made the necessary findings at to origin and
disposition pursuant to Public Resources Code Section 15097.98. If the remains are determined
to be of Native American descent, the coroner has 24 hours to notify the Native American
Heritage Commission (NAHC). After the find has been appropriately mitigated, work in the
area may resume. A qualified Chumash monitor shall oversee any mitigation work associated
with prehistoric cultural material.
The following two measures were incorporated into the Robinson Ranch Trail Final
Environmental Assessment (U.S. Forest Service, June 2000), and are intended to address
potential impacts to cultural resources:
CRS -1 In the event that archaeological resources are unearthed during project
construction, all earth disturbing work wilthin the vicinity of the find shall be
temporarily suspended or redirected until an archaeologist has evaluated the
nature and significance of the find. After the find has been appropriately
mitigated, work in the area may resume. A qualified Chumash monitor shall
oversee any mitigation work associated with prehistoric cultural material.
CRS -2 If human remains are unearthed, State Health and Safety Code Section 7050.5
requires that no further disturbance shall occur until the County Coroner has
made the necessary findings at to origin and disposition pursuant to Public
Resources Code Section 5097.98. If the remains are determined to be of Native
American descent, the coroner has 24 hours to notify the Native American
Heritage Commission (NAHC).

Addendum to FOR
A-4. No Subsequent EIR is Necessary
The proposed revision to information presented in the 1996 Final EIR involves clarification of the
intent of the assumptions related to the use of the impacts of the trail component of the project.
The City of Santa Clarita City Council has already taken action on the whole of the project, and no
additional actions are required.
Since the Final EIR always contemplated the trail component, and since the underlying
development pattern for the project area has not changed, the proposed action does not require a
Subsequent EIR. Specifically,
no major revisions of the previous EIR are required because there are no new signiftcant
environmental effects nor any substantial increase in the severity of previously identified
significant effects (Guidelines Section 15162(a)(1));
no substantial changes with respect to the circumstances under which the project is undertaken
due to new significant environmental effects or a substantial increase in the severity of
previously identified signficant effects have occurred (Guidelines Section 15162(a)(2));
the new information included in this Addendum would not (a) result in any new significant
effects, (b) no signficant effects would be more severe than shown in the Final EIR, (c) no new
mitigation measures or alternativesfound to be infeasible would infact befeasible, and (d) no
new mitigation measures or alternatives which are considerably dfferentfrom those analyzed in
the previous EIR have been identified which would substantially reduce one or more signficant
effects on the environment (Guidelines Section 15162 (a)(3)).
A-5. Intended Uses of the Addendum
This Addendum EIR, together with the Final EIR for the Hunters Green Residential and
Development Goff Course, is intended to be used as an informational source that provides an
update of the environmental documentation on the project pertaining to the trail component.
Under the State CEQA Guidelines, an addendum to an EIR need not be circulated for public
review, but can be attached to or included within the Final EIR.
