GENERAL STANDARDS:
- Except as modified by conditions of approval herein, this decision
recommends approval of the French Ranch Master Plan Amendment
to the Board of Supervisors and approves the Precise Development
Plan, and Vesting Tentative Subdivision Map for 33 dwelling units,
including the existing residence on the project site (Lot 22),
the creation of 31 single family residential lots within five
designated building areas (Building Areas 1-5), and a ranch manager's
residence for the equestrian center approved herein (Lot 23),
design approval for 18 single-family residences on Lots 1-9 and
13-21, an equestrian center with the capacity for 20 horses in
paddocks and 15 horses in a pasture (Lot 23), a ranch manager's
office at the equestrian center (Lot 23), an Advanced Integrated
Wastewater Pond System (AIWPS) for the proposed residences, equestrian
center, and the adjacent Lagunitas School District facilities,
the use of treated waste water from AIWPS for irrigation of recreational
fields and landscaping at the Lagunitas School District facilities,
the San Geronimo Valley Golf Course, and landscaping within the
French Ranch project area, an enhanced wetlands area (Parcel A),
infrastructure serving the residential, equestrian and sewer system
uses, dedication of approximately 463 acres or more of open space
(Parcel C) and associated trail easements to the County, enhancement
of riparian and native grassland areas, new landscaping within
development areas, and the creation of an approximately 3-acre
agricultural parcel (Parcel D) on property identified as Assessor's
Parcel Number 168-250-29, and 6400 Sir Francis Drake Boulevard,
San Geronimo. This approval permits the 26 residential lots granted
by the French Ranch Master Plan in addition to seven additional
dwellings pursuant to a State Density Bonus according to Government
Code Section 95615 and Marin County Code Chapter 22.97. The developer
shall construct at least three very low income dwelling units,

2) Stops fill haul truck activity along Sir Francis Drake Boulevard
15 minutes before the end of the school day on those days when
the Lagunitas School Complex lets out before 2:00 PM; and
- An evaluation of pre-construction pavement conditions along Sir
Francis Drake Boulevard between San Anselmo and the project site,
and Nicasio Valley Road between Lucas Valley Road and Sir Francis
Drake Boulevard. This evaluation shall be prepared in coordination
with the public works departments from Towns of Fairfax and San
Anselmo. The applicant shall reevaluate roadway conditions after
project completion in order to determine if project truck traffic
causes any additional pavement deterioration beyond normal wear
and tear. The project applicant shall be fully responsible for
repairing any pavement deterioration caused by project construction
traffic to pre-project conditions in conformance with the State
Streets and Highway Code. (Master Plan Condition 25)
- Prior to issuance of Building Permits for residential development,
the applicant shall pay its fare share of the necessary traffic
improvements to mitigate cumulative traffic impacts at the Nicasio
Valley Road/Sir Francis Drake Boulevard intersection. Presently,
the project's share is estimated at $2,000 per unit, or $50,000.
The applicant shall work with the DPW to establish the actual
cost of necessary improvements, and shall make arrangements to
pay its fair share of these improvement costs. (Master Plan Condition
26)
- Pursuant to the Marin County Congestion Management Program (CM),
the applicant shall pay to the County traffic mitigation fees
which are in effect at the time and Building Permits are issued
for the project. (Master Plan Condition 27)
EQUESTRIAN CENTER:
- Prior to issuance of Improvement Plans, Grading Permits, or Building
Permits for the Equestrian Center, the applicant shall submit
a final management plan for the equestrian center to the Community
Development Director for review and approval. This plan shall
be prepared in consultation with the California Department of
Fish and Game, the Regional Water Quality Control Board, and the
Marin Municipal Water District to ensure that it adequately protects
water quality in the project vicinity. Among other things, this
plan shall include the information listed below.
- Provide a detailed description of the use and operation of the
equestrian facility.
- Establish a program for manure collection, storage, and disposal.
This program may include a plan for composting manure on-site.
If manure is not composted, manure storage should be temporary,
with frequent scheduling of waste removal to an appropriate disposal
or treatment site. Details of any composting and/or removal program
should be included in the stormwater management program submitted
to the County under the NPDES stormwater permit guidelines.
- The final construction drawings shall include diversion system
for stormwater runoff in and upslope of the outdoor paddock and
stabling areas at the equestrian center. Upslope runoff that would
naturally enter the equestrian facilities should be collected
in grass-lined drainage channels and routed around the area to
prevent contamination and to lessen the potential entrapment of
suspended material in runoff. Immediately following construction,
it would probably be necessary to protect the newly graded channels
with an erosion control blanket until an adequate cover is established.
- The final construction drawings shall include a detention basin
along the intermittent drainage (Stream B), revegetation of cut
slopes above the parking area to the equestrian center with native
grasslands with a cover class 4, and restrictive fencing in the
pasture area to protect existing native grasslands, restored native
grasslands, and seeps. (Negative Declaration Mitigation 7-1)
- Demonstrate that all stabling and waste storage areas will be
constructed to be free of intrusion by direct rainfall or runoff
from outdoor paddock areas, and so that all interior floors are
sloped toward the rear walls with no drainage outlets to facilitate
waste removal and to prevent the movement of the waste into earthen
paddock areas.
- Provide for minor site grading in the equestrian center to direct
all surface runoff emanating from the outdoor paddock areas and
riding ring so that they are conveyed overland across a buffer
strip a minimum distance of 100 feet to the nearest drainageway.
The overland travel path between the use areas and the culvert
inlet shall be seeded and mulched with native species that establish
a thick, continuous cover rather than a sparser bunched form,
to promote quick grass establishment. Under no circumstances shall
the stable/paddock/riding ring runoff be discharged directly (i.e.
without interim overland filtering) into the drainage channels
that convey uncontaminated upslope runoff. If overland runoff
buffer strips measuring 100 feet or more is not feasible, the
applicant shall construct detention basin(s), or other acceptable
engineering solutions, for the purpose of settling out suspended
sediments and absorbed contaminants.
- Establish strict controls on the use of toxins to guard against
the migration of toxins from stables and riding grounds to local
drainages and the San Geronimo Creek.
(Master Plan Condition 30)
The management plan shall be incorporated into the Improvement
Plans, Grading Permit, and Building Permits, as appropriate, for
review and approval by the Community Development Director.

other noxious weeds.
- Salvage native bunch grasses by the landscape contractor before
site grading and replanting within the development area.
- Protect native grasses within individual lots and native grasses
in undeveloped open space areas from construction disturbance
by installing flagging and conspicuous fencing.
- Use fast growing native grass species in all erosion control and
hydroseed mixtures used on site.
- Remove broom and other aggressive weedy plants from bare mineral
soils.
- Stringently control pans for landscaping in the vicinity of residences
to prevent further loss of native grassland cover. Preservation
and enhancement of native grasslands should be integrated into
the individual landscape plan for each residence located adjacent
to grasslands where native cover exceeds ten percent.
(Master Plan Condition 40)
