Section 2.
FINDINGS AND DETERMINATIONS
Pursuant to Section 8.32.070 of the Dublin Municipal Code, the City Council finds as follows:
1. The Project, known as the Storm Water Quality Control Basin within Area H of Dublin
Ranch (Lin Family), Stage 2 Development Plan meets the purpose and intent of Chapter
8.32 in that it provides a comprehensive development plan that is compatible with and
sensitive to the surrounding uses by virtue of the layout and design and would create an
aesthetic, innovative, and ecologically appropriate use for a facility required as a condition
for implementation of the Dublin Ranch Master Plan.
2. Development of the Storm Water Quality Control Basin within Area H of Dublin Ranch
(Lin Family) under the Stage 2 Development Plan will be harmonious and compatible with
existing and future development in the surrounding area in that the land uses and site plan
integrate a required storm water treatment facility with passive recreational space, open
space, and the natural environment.
Pursuant to Section 8.120.050.A and B of the Dublin Municipal Code, the City Council finds as follows:
1. The Stage 2 Development Plan for the Storm Water Quality Control Basin within Area H
of Dublin Ranch will be harmonious and compatible with existing and potential
development in the surrounding area in that the land uses and site plan integrate a required
storm water treatment facility with passive recreational space, open space, and natural
environment and provides an effective transition to surrounding development.
EXHIBIT A
2. The Stage 2 Development Plan for the Storm Water Quality Control Basin within Area H
of Dublin Ranch has been designed to accommodate the topography of the Project site
which typically is characterized as vacant, flat land suitable for the development of a storm
water detention basin enhanced with passive recreational open space areas and natural
habitat and therefore physically suitable for the type and intensity of the proposed Stage 2
Development Plan.
3. The Stage 2 Development Plan will not adversely affect the health or safety of persons
residing or working in the vicinity or be detrimental to the public health, safety, and
welfare in that the Project will comply with all applicable development regulations and
standards and will implement all adopted mitigation measures.
4. The Stage 2 Development Plan is consistent with the Dublin General Plan, Eastern Dublin
Specific Plan, and the Stage I Development Plan for Area H of Dublin Ranch (Ordinance
No. 06-00) as it is in conformance with the land use designation of Planned Development
Campus Office and General Commercial that allows the proposed use.
Pursuant to the California Environmental Quality Act, the City Council finds as follows:
1. In 2000 an Initial Study was prepared for P A 98-070, the Stage I Planned Development
approval for Area H (SCH #99-1120412), and a determination was made that the project is
within the scope of the Eastern Dublin Specific Plan and General Plan Amendment, for
which a Program EIR was certified (SCH #91-103064) in 1993 including revisions to Part
I of the Responses to Comments relating to the Kit Fox, the Addendum to the DEIR dated
May 4, 1993, and a DKS Associates Traffic Study dated December 15, 1992 ("Eastern
Dublin EIR"). The City also adopted a mitigation-monitoring program, which included
numerous measures intended to reduce impacts from the development of the Eastern
Dublin area. The timing for implementation of these mitigation measures is summarized in
the adopted Mitigation and Monitoring Program matrix; and
2. The Initial Study prepared for P A 98-070, the Program EIR along with all subsequent
Supplements, and the adopted Mitigation and Monitoring Program adequately address
anticipated environmental impacts resulting from the proposed project for the purpose of
compliance with CEQA.

10. Site Plan and Architecture
This Development Plan applies to approximately ± 11.196 acres comprising Lot 3 of Parcel
Map 8640 located north of 1-580, south of the proposed extension of Dublin Boulevard, and
in general between the proposed extensions of Brannigan Street on the west and Keegan
Street on the east. Since no structures are proposed for the site, architecture is limited to the
structural elements of the storm water quality control basin.
Design Concept:
. Stormwater Treatment - In accordance with the Stormwater Quality Management Plan,
the water surface area will be 4.1 acres with a volume of 19.5 acre/feet and holding time
of 48 hours to promote the settling of particles and debris. The basin features and
stormwater treatment parameters are the primary elements in accomplishing the purpose
of this facility. The storm water runoff will be channeled from two locations: 1) from
the north along Grafton Street parallel to Tassajara Creek, and 2) from the east in the G3
channel. Then it will be diverted by gravity flow into the basin from two inlet structures
located along the south side of the site and discharged into two sedimentation forebays
located near the southeast and southwest corners of the site.
3
Stage 2 Development Plan
PA 05-005 Storm Water Quality Control Basin
Dublin Ranch Area H
The forebays will be separated from the main basin by gabion structures and 6 to 8 foot
berms stabilized with rock and riprap to prevent erosion. When water within the forebays
reaches a certain level, it will fall into the main basin area and meander through low flow
channels to the permanent pool. The permanent pool is equipped with a gravity flow
outfall through which the water will be pumped and discharged back into the G3 channel
where it would continue westward.
The shape of the basin landform along with a variety of slopes will be designed to create
visual interest while being efficient and maintainable. The sedimentation forebays,
approximately 150 feet by 50 feet each, will be permanent pools ringed by native plants.
A variety of side slopes and elevations within the main basin will provide filtration
trough vegetation as well as a biochemical process. The main basin floor will be graded
to create a series of islands 4 to 8 feet above the minimum pool level. The low-flow
channels would have a minimum depth of 4 feet and a maximum depth 8. Bottom width
would be from 4 to 8 feet with the top width varying between 16 and 30 feet. The design
is intended to allow a minimum required holding time of 48 hours.
Average depth with in the main basin, excluding forebays and permanent pool, will be 5
feet; however, during a 100-year storm event the average depth maybe as high as 16 feet
with the forebays and permanent pool potentially being deeper. From the low-flow
channels, the water would flow into the permanent pool through a number of oxidization
zones over series of weirs. In addition to adding a visual water element to the basin, the
weirs provide continuous movement and aeration helping to prevent the growth of algae
and invasive plant species. The permanent pool, near the northwesterly boundary of the
site, will have a surface area of approximately 11,000 square feet. It will be separated
from the sedimentation forebay near the southwest corner of the site by a landscaped
divider ridge to reduce the visual scale ofthe basin area and eliminate the appearance as a
large, single depression. The actual depth and elevation of the permanent pool will
depend upon the groundwater level.
. Maintenance and Access - In addition to the landscape buffer, a road or pathway with a
minimum width of 15 feet encircles the Water Quality Control Basin. Portions of the
route are accessible by maintenance vehicle. Primary access for maintenance vehicles
will be from an existing gated entry at the southwest corner of the site where the end of a
cul-de-sac is located on an existing freeway frontage road used to service CalTrans right-
of-way for 1-580 and the G3 flood control channel. This maintenance road forks into
access roads to each of the two sedimentation forebays on either side of a pedestrian
overlook. A second IS-foot wide path, with gated access off the perimeter path, also
provides maintenance vehicle access to two sides of the permanent pool; a vehicle turn-
around area is located at the end of path. The basin floor also is accessible at three points
from the maintenance roads.
Limited public access to the site will be made available in the form of pedestrian paths,
eight feet in width, around the full perimeter of the site. Pedestrian access points will be
located at the northwest and northeast corners of the site with a stabilized crushed stone
surface suitable for walking, jogging, cycling, dog-walking, or general use. A 4-foot high
security fence will be used to identify public open space and limit access to the basin.
This type of fence will be an open mesh system between posts with effects similar to
4
Stage 2 Development Plan
PA 05-005 Stprm Water Quality Control Basin
Dublin Ranch Area H
ranch walls or equestrian corrals leading through oak groves and woodlands.
Appropriate signage limiting use by pedestrians and the public would be posted.
A second type of fencing would be located along the northerly property line adjacent to a
pedestrian promenade and would include a design feature along with a second overlook
point. Due to its visibility, this fence presents an excellent opportunity to incorporate
public art and an interesting pedestrian edge. The design of this "'Art Fence," as it is
referred to, may include custom panels or graphics which would be coordinated through
the Dublin Fine Arts Foundation. The specific art applied to the wall panels would need
further coordination, but might feature elements related to storm water management,
wildlife habitat, weather, and seasonal themes. The pedestrian circulation system also
would include lighting along the promenade and "'Art Fence" and within the two
overlook areas. The 6-foot high chain-link fence adjacent to the 1-580 CalTrans right-of-
way would be maintained as is. In addition to clean out activities related to maintenance,
mosquito abatement and a vector control program have been coordinated with the
appropriate agencies.
See attached project plans and exhibits prepared by Conger, Moss & Guillard, landscape
architects, dated received July 22, 2005 referred to as Project Plans labeled Exhibit A to the
City Council Staff Report, stamped approved and on file in the Community Development
Department and the Applicant's written statement. Such project plans are incorporated by
reference. Any modifications to the project shall be substantially consistent with these plans
and of equal or superior materials and design quality.
11. Preliminary Landscape Plan
The basin largely would be screened by low land forms and tree plantings along the easterly,
westerly, and southerly edges. The east and west edges are partially screened by oak
plantings to create a park-like environment and to screen potential parking areas from
eventual commercial development on either side. The frontage along 1-580 has been
designed to screen the basin from view and provide passing vehicles with an attractive but
subtle landscape buffer. The intent is to create a foreground for distant views to the
surrounding hillsides. The pedestrian promenade along the north edge of the basin will
provide a transitional buffer for future development on the adjacent property within Area H.
In keeping with the Storm Water Management Plan, the landscape and planting design will include a
variety of native species, grasses, woody shrubs, and trees, as well as selected non-native species in
distinct areas along the basin top perimeter. The top of the slopes and perimeter plantings would be
more formal and uniform for compatibility with the streetscape of future development anticipated for
Area H. The side slopes of the basin would be planted with a mixture of native grasses, shrubs, and
trees to create an environment similar to the regional hills. The lower part of the basin would be
planted with a variety of native plants with a naturalistic condition similar to a stream corridor. The
planting design along the low-flow channel and within the basin floor aims to maximize water
treatment functions while establishing a self-sustaining riparian habitat. The level and type of
vegetation management and maintenance will be by zone according to the type of plantings and the
image to be created.
