On August 27, 2002, by Resolution No. 2651, City Council approved Final

On April 22, 2003, by Resolution 2832, City Council approved a Reimbursement

On September 2, 2003, the Planning Commission amended Resolution No. 01-53
amending the Conditions of Approval for Tentative Subdivision Map No. 8424.
This subdivision, located north of Chestnut Street and east of Garin
Parkway, contains 252 single-family residential lots. All public
improvements required by the Conditions of Approval for this subdivision
have been constructed and inspected for conformance with the approved
improvement plans including sewer, water and storm drain lines, sidewalk,
paving, streetlights and fiber optics. As a part of this project, William
Lyon Homes constructed the 10 acre Heron Park and Detention Basin, extended
Garin Parkway north of Chestnut Street to Sycamore Avenue, extended
realigned Chestnut Street easterly to Sellers Avenue and constructed master
planned nonpotable water facilities. The Developer has worked with the
Contra Costa County Flood Control District for the last few years towards
design and construction approval of the outfall structure that will connect
the detention basin at Heron Park with Storm Drain Line A to ultimately
drain this site northerly to Marsh Creek. The Flood Control District has not
yet completed the design of this facility, which is proposed to be owned and
operated by the District. As an interim measure, the Developer’s contractor
has installed storm drain lines from the basin to the Storm Drain Line A
trunk line, in the event a portion of the basin will need to be drained
during the rainy season. Approval by the District is anticipated by the end
of December and William Lyon Homes has posted a Performance Bond
guaranteeing completion of the structure upon approval and as soon as
weather permits. William Lyon Homes has provided a Maintenance Bond to cover
the twelve-month warranty period for all improvements in the subdivision
that have been completed.
As required by the Conditions of Approval and shown on the improvement
plans, the Developer has installed the following improvement quantities:
7,495 LF of 8” sewer lines, 1,650 LF of 12” sewer lines, 14,900 LF of 8”-20”
waterlines, 3,308 LF of 12” and 20” nonpotable waterlines, 12,434 LF of
18”-66” storm drain lines, 36,715 LF of curb and gutter, 173,215 LF of 5’
and 10’ sidewalk, 12,986 LF of pavement, 101 streetlights, 12,600 LF of
joint trench including fiber optic conduit and a 10 acre park and detention
When the Final Map was approved by the City Council, the right-of-way offers
of dedication were accepted subject to acceptance of improvements. The
improvements are now installed to support the new lots; therefore, it is the
appropriate time to accept the improvements, rights-of-way and easements as
offered on the Final Map.
Upon acceptance of improvements the City will incur annual costs associated
with necessary maintenance of streets, landscaping and utilities. Routine
roadway maintenance will be funded by the General Fund and Measure “C” gas
tax, with sewer and water maintenance funded through their respective
enterprise funds. Landscaping and Lighting Assessment District (LLD) No.
02-2 has been formed for this subdivision and will be responsible for the
street lighting and landscape maintenance.
