EXHIBIT A
SUPPLEMENTAL FINDINGS WITH RESPECT
TO THE ROGUE RANCH GENERAL PLAN AMENDMENT
I. GENERAL FINDINGS
A. The General Plan Amendment is in the public interest in
that it will help meet the need to increase the housing supply in the
County, in a range of densities providing for a variety of family
sizes, income levels and age groups, in order to accommodate the
County's growing population and employment base, and the need to pre-
serve open space and agricultural land within the County on a per-
manent basis.
B. For the reasons set forth in the Planning Department
Staff Report, dated November 7, 1984, the General Plan Amendment is
consistent with and will help to further the goals and objectives of
the General Plan.
C. The General Plan Amendment designation for the southwest
130± acres of the site (Low Density Single Family Residential (1 to 3
units per acre)} is compatible and consistent with the General Plan
designations for the surrounding area.
D. The General Plan Amendment will allow flexibility in
planning to achieve the housing goals of the General Plan without
Intruding on the development pattern and lifestyle of the residents of
Alamo.
E. The General Plan Amendment is only the first of a number
of discretionary approvals that must be obtained by applicant prior to
_1_
commencement of any development project for the site. Subsequent
approvals that must be obtained include those for rezoning of the
property from A-2 to P-1,' planned unit district, for a preliminary and
final development plan, for a tentative map and for reorganization of
various boundaries for certain special districts.
F. The General Plan Amendment of itself will not directly
result in any significant effects on the environment. The EIR,
prepared at the time of the General Plan Amendment request, addresses
impacts which may be attributable to the development of a project for
the site that has only been proposed in concept by applicant. Further
environmental review and consideration, including the implementation
of any appropriate mitigation measures or project alternatives, will
necessarily occur during the approval process for any development
project for the site which may subsequently be submitted. To the
extent that any of the impacts identified in the EIR may be indirectly
attributable to the General Plan Amendment, explanations of mitigation
and statements of overriding considerations with respect to those
Impacts are set forth in the findings under paragraph II below.
II. CEQA FINDINGS ON THE SIGNIFICANT ENVIRONMENTAL EFFECTS
IDENTIFIED IN THE EIR AND STATEMENT OF OVERRIDING
CONSIDERATIONS
A. Findings, Explanation Of Mitigation And Statement Of
Overriding Considerations Justifying The General .Plan
Amendment Regardless Of Any Remaining Impact For The
Identified Sianificant Effect Upon Geoloav And Soils.
The EIR identifies potential geological impacts in that
damage from earthquakes could result from ground vibration transmittal
-2-
to a project site from the area of the earthquake, or from primary
surface breakage along an active fault which runs through a project
site, and that development of the project as originally proposed in
concept would involve extensive deep-fill grading and possible surface
erosion. Potential earthquakes or. surface breakage would not
significantly affect the proposed project. However, during review of
any development project for the site which may be submitted after
General Plan amendment, the design of the project will consider the
location of units and their design in accordance with the Uniform
Building Code, other pertinent laws, and recommendations from soil
engineers, geologists and civil engineers. The project is proposed
within 130+ acres of relatively gentle terrain which will minimize
soil problems. To the extent any such geological or soils impact
attributable to the General Plan Amendment remains unmitigated, this
Board finds such impact justified by the need to increase the housing
supply in the County, in a range of densities providing for a variety
of family sizes, income levels and age groups, in order to accommodate
the County's growing population and employment base, and the need to
preserve open space and agricultural land within the County on a
permanent basis. These needs make infeasible the complete mitigation
of such impact or the implementation of the "no project" alternative
described in the EIR. Further consideration and any implementation of
additional mitigation measures or the remaining alternatives described
In the EIR will occur during review of any development project for the
site which may subsequently be submitted.

B. Findings, Explanation Of Mitigation, And Statement Of
Overriding Considerations Justifying The General Plan
Amendment Regardless Of Any Remaining Environmental
Impact For The Identified Significant Effect Upon
Hydrology..
The EIR identifies hydrological impacts in that development
would result in increased runoff within the watersheds and possible
local flooding problems, particularly with respect to that area which
drains into Miranda Creek, whose flood plains are inundated during
even moderate intensity storms. A detailed evaluation of the
hydrology will be required during project review to mitigate these
Impacts. Such mitigation measures may include creation of detention
basins in larger sections of the on-site channels to control runoff.
The existing basins or ponds within the open space area are being
preserved to minimize runoff. To the extent any such hydrological
Impact attributable to the General Plan Amendment remains unmitigated,
this Board finds such impact justified by the need to increase the
housing supply in the County, in a range of densities providing for a
variety of family sizes, income levels and age groups, in order to
accommodate the County's growing population and employment base, and
the need to preserve open space and agricultural land within the
County on a permanent basis. These needs make infeasible the complete
mitigation of such impact or the implementation of the "no project"
alternative described in the EIR. Further consideration and any
Implementation of additional mitigation measures or the remaining
alternatives described in the EIR will occur during review of any
development project for the site which may subsequently be submitted.

C. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General
Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effect Upon Biotics.
The General Plan Amendment will allow 130± acres of grazing
land to be converted to urban growth area. The EIR identifies
potential resulting impacts on biotics in that mature oak trees may be
destroyed and siltation resulting from grading in steep drainage areas
would have serious effects on the creek bed off the property to the
southwest. In addition, development in close proximity to two parks
may result in periodic invasion of these parks by domestic pets and
other disturbances of park wildlife.
The proposed General Plan Amendment will result in the
preservation of two-thirds of the land (approximately 310 acres) in
Open Space that will be managed by the East Say Regional Park District
upon donation to the District. Applicant has proposed such a gift and
EBRPD has indicated that it will accept the dedication. Management of
the open space by EBRPD could provide for continued agricultural
activity. Cattle should be removed for one to two years to allow the
site to return to a natural grassland - oak woodland state.
Preservation of the approximately 310 acres in Open Space will save
the majority of the large oaks and mitigation measures can be imposed
during project review to ensure that design of the project and grading
of the site will result in the preservation of trees. The leash
ordinance should be strictly enforced. To the extent any impact upon
biotics attributable to the General Plan Amendment remains
-5-
unmitigated, this Board finds such impact justified by the need to
increase the housing supply in the County, in a range of densities
providing for a variety of family sizes, income levels and age groups,
in order to accommodate the County's growing population and employment
base, and the need to preserve open space and agricultural land within
the County on a permanent basis. These, needs make infeasible the
complete mitigation of such impact or implementation of the "no
project" alternative described in the EIR. Further consideration and
any implementation of additional mitigation measures or the remaining
alternatives described in the EIR will occur during review of any
development project for the site which may subsequently be submitted.
D. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General
Plan Amendment Regardless Of Any Remaining Environmental
Impact For The Identified Significant Effect Upon
Climate And Air Quality.
The EIR identifies potential short-term and long-term impacts
upon air quality, the short-term impact resulting from grading during
construction and the long-term impact being a function of vehicular
traffic after completion of project development. These impacts are
susceptible of mitigation as set forth in the EIR, including the
establishment of guidelines to control dust during construction and
the use of mass transit facilities. Such mitigation measures can be
implemented during project review. To the extent any such impact upon
climate or air quality attributable to the General Plan Amendment
remains unmitigated, the Board finds such impact justified by the need
to increase the housing supply in the 'County, in a range of densities
-6-
providing for a variety of family sizes, income levels and age groups,
in order to accommodate the County's growing population and employment
base, and the need to preserve open space and agricultural land within
the County on a permanent basis. These needs make infeasible the
complete mitigation of such impact or implementation of the "no
project" alternative described in the EIR. Further consideration and
any implementation of additional mitigation measures or the remaining
alternatives described in the EIR will occur during review of any
development project for the site which may subsequently be submitted.
E. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The
General Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effect Upon Acoustics.
The EIR identifies potential short-term acoustical impacts
resulting from project construction noise, particularly during grading
operations, and permanent noise increases resulting from a rise in
traffic levels due to the project. Noise increases along Miranda
Avenue - Livorna Road would be small but perceptible. Construction
noises may be reduced by contractors using quiet models of
construction equipment. Specific noise mitigation measures will be
considered during project review, including an acoustical study to
determine noise impacts and recommended mitigation, if any, along
Miranda Avenue, Livorna Road and at the entrance to the project. To
the extent any such acoustical impact attributable to the General Plan
Amendment remains unmitigated, this Board finds such impact justified
by the need to increase the housing supply in the County, in a range
-7-
of densities providing for a variety of family sizes, income levels,
and age groups, in order to accommodate the County's growing
population and employment base, and the need to preserve open space
and agricultural land within the .County on a permanent basis. These
needs make infeasible the complete mitigation of such impact or the
implementation of the "no project" alternative described in the EIR.
Further consideration and any implementation of additional mitigation
measures or the remaining alternatives described in the EIR will occur
during review of any development project for the site which may
subsequently be submitted.
F. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General _
Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effect Upon Traffic.
The General Plan Amendment will allow development to occur
that will result in increased traffic. The EIR identifies traffic
impacts off-site to Livorna Road, Miranda Avenue, Stone Valley Road
and Roundhill Road primarily. These impacts can be mitigated during
project design and review with mitigation measures as suggested in the
EIR, including improvements to Miranda Avenue and Livorna Road and the
extension of Livorna Road through the Post property. To the extent
any such traffic impact attributable to the General Plan Amendment
remains unmitigated, this Board finds such impact justified by the
need to increase the housing supply in the County, in a range of
densities providing for a variety of family sizes, income levels and
age groups, in order to accommodate the County's growing population
-8-
I
and employment base, and the need to preserve open space and
agricultural land within the County on a permanent basis. These needs
make infeasible the complete mitigation of such impact or the
implementation of the "no project" alternative described in the EIR.
Further consideration and any implementation of additional mitigation
measures or the remaining alternatives described in the EIR will occur
during review of any development project for the site which may
subsequently be submitted.*
G. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General
Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effects Upon Services And Facilities.
The General Plan Amendment will allow development to occur in
an area where urban services should logically be provided from the San
Ramon Valley instead of Diablo Valley. The EIR identifies cumulative
impacts upon services and facilities within the San Ramon Valley with
respect to fire protection, police services, water service, sewage,
solid waste, public schools and parks and recreation.
The site is almost entirely within the Contra Costa County
Consolidated Fire District. A small southerly portion of the property
is within the San Ramon Valley Fire Protection District (SRVFPD).
With respect to fire protection Impacts, the proposed project in
Itself would not significantly burden either district. Applicant
wishes to place the entire site within SRVFPD. Such a request must be
made of LAFCO. The Sheriff's Department could serve the project
without additional manpower or equipment. With respect to the solid
-9-
waste impact, the project site would be served by Valley Disposal
Service and Acme landfill. Recycling should also be encouraged of
project residents. Approximately 310 acres will be permanently
preserved for parks and recreation upon donation to East Bay Regional
Park District. The site is located within the Mt. Diablo School
District and a transfer of the property from that district to San
Ramon Unified School District has been recommended by the County
Superintendent of Schools. Both districts have indicated that they
would agree to the transfer.
With respect to water service, sewage and public schools
impacts, an application for reorganization of various boundaries .and
jurisdiction will also need to be filed with LAFCO or the County
Superintendent of Schools, as appropriate, for final determination of
boundaries. During project review, project plans will be submitted to
the various districts and agencies for recommendations to mitigate
impacts. To the extent any such impact upon services and facilities
attributable to the General Plan Amendment remains unmitigated, the
Board finds such impact justified by the need to increase the housing
supply in the County, in a range of densities providing for a variety
of family sizes, income levels, and age groups, in order to
accommodate the County's growing population and employment base, and
the need to preserve open space and agricultural land within the
County on a permanent basis. These needs make infeasible the complete
mitigation of such impact or the implementation of the "no project"
alternative described in the EIR. Further consideration and any
-10-
implementation of additional mitigation measures or the remaining
alternatives described in the EIR will occur during review of any
development project for the site which may subsequently be submitted.
H. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General
Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effect Upon Visual And Aesthetic Considerations.
The General Plan Amendment of itself will not create any
visual impacts. The EIR identifies visual and aesthetic impacts in
that development in the southwestern portion of the site and the
potential. site of a EBMUD water storage site would be visible either
from homes along Miranda Avenue and Roundhil . North or from
surrounding parklands. Major mitigations to development of the site
have been incorporated into the conceptual project design. The
approximately 310 acres left undeveloped would remain a major visual
amenity to park users. The knolls and stands of oak left untouched by
development will constitute a major amenity to future residents of the
sites. Hills screen most of the area proposed for development from
view. Further studies by the water district will be conducted to
determine the preferred placement of the tank. To the extent any such
impact upon visual and aesthetic considerations attributable to the
General Plan Amendment remains unmitigated, this Board finds such
impacts justified by the need to increase the housing supply in the
County, in a range of densities providing for a variety of family
sizes, income levels and age groups, in order to accommodate the
County's growing population and employment base, and the need to
-11-
preserve open space and agricultural land within the County on a
permanent basis. These needs make infeasible the complete mitigation
of such impact or the implementation of the "no project" alternative
described in the EIR. Further consideration and any implementation of
additional mitigation measures or the remaining alternatives described
in the EIR will occur during review of any development project for the
site which may subsequently be submitted. -
I. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The
General Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified Significant
Effect Upon Energy Resources.
The EIR identifies a significant effect upon energy resources
in that residential development within the proposed project area would
commit significant amounts of energy and building materials to the
construction of roadways, storm drainage, utilities and residential
buildings. Review of project design and construction will insure that
energy conservation measures will be incorporated. Regardless of the
ultimate architectural designs and subdivision plans, all of the new
residences must conform to building code regulations for energy
conservation. They must also comply with State energy conservation
requirements, as set forth in Title 24 of the California
Administrative Code. To the extent any such impact upon energy
resources attributable to the General Plan Amendment remains
unmitigated, the Board finds such impact justified by the need to
increase the housing supply in the County, in a range of densities
providing for a variety of family sizes, income levels and age groups,
-12-
in order to accommodate the County's growing population and employment
base, and the need to preserve open space and agricultural land within
the County on a permanent basis. These needs make infeasible the
complete mitigation of such impact or the implementation of the "no
project" alternative described in the EIR. Further consideration and
any implementation of additional mitigation measures or the remaining
alternatives described in the EIR will occur during review of any
development project for the site which may subsequently be submitted.
J. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The
General Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Potential Significant
Effect Upon Archeology.
The EIR states that no known archeological or historic site
was located within the project area. One area of bedrock mortar was
found near a seasonal drainageway. No other evidence of archeological
resources was discovered. The bedrock mortar area has been recorded
and will be reported to the California Site Survey. There is a remote
possibility of a deeply buried site being uncovered during excavation.
Possible mitigation measures, including stoppage of work where
necessary for archeological consultation, will be considered during
project review. To the extent any such archeological impact
attributable to the General Plan Amendment remains unmitigated, the
Board finds such impact justified by the need to increase the housing
supply in the County, in a range of densities providing for a variety
of family sizes, income levels and age groups, in order to accommodate
the County's growing population and employment base, and the need to
-13-
preserve open space and agricultural land within the County on a
permanent basis. These needs make infeasible the complete mitigation
of such impact or the implementation of the "no project" alternative
described in the EIR. Further consideration and any implementation of
additional mitigation measures or the remaining alternatives described
in the EIR will occur during review of any development project for the
site which may subsequently be submitted.
K. Findings, Explanation Of Mitigation, And Statement
Of Overriding Considerations Justifying The General
Plan Amendment Regardless Of Any Remaining
Environmental Impact For The Identified
Significant Effect Of Inducing Growth.
The EIR identifies a growth-inducing impact in that the
clustered development proposed in concept by applicant would be
precedent setting and potentially encourage similar density
development in the area. The clustering of units may be unique to the
Alamo community, but the proposed limitation of development to 130±
acres of the approximately 441 acre site in conjunction with the
proposed preservation of the remaining 310± acres in Open Space is in
accordance with the General Plan objectives of protecting the natural
features of the area to encourage the preservation of the watershed,
the natural appearance of hillsides and ridges, and the natural beauty
of the area. Management of the open space by EBRPD for continued
grazing activity will also serve to relieve more viable agricultural
lands from pressure to convert to urban growth. Review of any
development project for the site will consider, to the greatest extent
possible, the harmonization of project design with the unique
-14-
character of the Alamo community. To the extent any such
growth-inducing impact attributable to the General Plan Amendment
• remains unmitigated, this Board finds such impact justified by the
need to increase the housing supply In the County, in a range of
densities providing for a variety of family sizes, income levels and
age groups, in order to accomodate the County's growing population and
employment base, and the need to preserve open space and agricultural
land within the County on .a permanent basis. These needs make
infeasible the complete mitigation of such Impact or the
implementation of the "no project" alternative described In the EIR.
Further consideration and any implementation of additional mitigation
measures or the remaining alternatives described in the EIR will occur
during review of any development project for the site which may
subsequently be submitted.
