~SCRIPTION : At the October 14, 1985 meeting of the Dublin City
~ ~uncil, the City Council retained the services of Singer & Hodges, Inc., to
develop a park development plan for the City of Dublin. The City Council
directed that the following park sites be included in the park development
plan: Dolan, Dougherty Hills Open Space, East Dougherty Hills, Mape, Kolb &
Shannon.
Over the last 4 months, numerous neighborhood meetings have been held to
provide input on the preliminary park design for these various parks. At
its meeting of April 8, 1986, the Park & Recreation Commission finalized its
recommendations for the preliminary park design for all 6 parks. A complete
report from Singer & Hodges will be presented to the Council at its meeting
of April 28, 1986 on all parks.
In accordance with earlier City Council direction, Staff has prepared a
report for the City Council regarding the preliminary park design for the 8
acre East Dougherty Hills park site in order that the developer of the Alamo
Creek Villages can proceed with the grading of the park in conjunction with
the residential development as soon as possible. The preliminary design for
the East Dougherty Hills park site (see attached) was approved by the Park &
Recreation Commission at its meeting of April 1, 1986. Singer & Hodges will
be present at the City Council meeting to go over this plan in detail for
the City Council. The Park & Recreation Commission did make a
recommendation with respect to the park that would have a substantial impact
on the City financially as well as necessitate an early decision with
respect to this park in order that the Commission's recommendation could be
sommodated into the grading plan for the park. The Park & Recreation
commission approved a design which would call for the regarding and widening
of the creek for aesthetics, better surveillance and greater accessibility
by 'the public. If the City Council were to approve the Park & Recreation
Commission's recommended park design, the City would be required to enter
into a joint use agreement with the Alameda County Flood Control & Water
Conservation District/Zone 7, redesign the channel configuration, and get
Zone 7's approval, and assume maintenance and liability responsibility for
the creek within the park.

East Dougherty Hills Park Design
Attached to this report is the park development cost estimates for the
preliminary park design alternatives. As agreed upon, at the City Council
meeting of March 24, 1986, the Developer of the Villages @ Alamo Creek will
be responsible for the construction.of the Phase I basic park improvements
in accordance with the City's design and specifications. Based on the
revised design recommended by the Park & Recreation Commission, the
estimated cost to the Developer for these basic park improvements is
$666,380. As shown in the park development cost estimate, the cost to the
City for the Phase I development of the park will vary depending upon what
the City Council agrees is the appropriate configuration for the creek
within the park. Staff has identified 3 options available to the City
Council with respect to the creek issue.
Option %1 - The creek is designated as a flood control channel in accordance
with Zone 7 specifications. This would require that the creek be fenced off
and would not be accessible to park users. Zone 7 would be responsible for
maintenance as well as any liability.
Cost to the City - $0
O~tion %2 - The creek is accepted by the City as part of the park in
~ordance with the creek section proposed by the developer. Limited
improvements are undertaken to make the creek more accessible to park users.
These improvements would include clearing, revegetation and a series of
walkways in order for park users to get down into the creek. The creek
would be fenced off during the winter months when the water level is
determined to be hazardous. The City would have to develop a joint use
agreement with Zon~ 7 and would be required to assume maintenance and
liability responsibility for the creek.
Cost to the City - $134,130
Option %3 - The creek is accepted by the City as part of the park. In order
to make the creek more visible and physically accessible, the east side of
the creek would be regraded and widened. A grassy slope would be maintained
along the creek edge and a low flow crossing developed to provide access
across the creek from one side of the park to the other. The creek area
would be revegetated and trails developed. This option would provide park
users with much greater access to the creek. This option would also require
the City to develop a joint use agreement with Zone 7 and assume liability
and maintenance responsibility for the creek.
Cost to the City - $417,570
If the City Council is interested in either Option %2 or Option ~3 with
respect to the creek design, it is highly desirable that these improvements
accomplished during the development of the Phase I basic park
e~nstruction. If the City waited to make these improvements, the cost for
these improvements would increase. If the City were to pursue either Option
~2 or Option #3, it is quite likely that these improvements would have to be
financed from appropriations from the City's existing reserves since there
will not be sufficient park dedication funds available without inhibiting
the development of other parks within the City.
The park development cost estimate (see attached) also indicates that the
Phase II park improvements recommended by the Park & Recreation Commission
would cost approximately $189,970.
It is the Park & Recreation Commission's recommendation that the City
Council approve the park design with the creek development identified in
Option ~3.
It is Staff's recommendation that the City Council 1) hear the presentation
from Singer & Hodges, 2) consider all three creek development options and an
approve the desirable design, and 3) authorize Staff to take the necessary
steps to implement the Council's approved design.
