BACKGROUND:
The City's Stormwater Drainage Master Plan provides a thorough review of the City's
drainage deficiencies and lists specific capital project recommendations to address
system deficiencies. Given budget restraints, staff has systematically performed one
major drainage project per year in keeping with the plan's priorities. The current
drainage improvement involves the Platino Lane and Oro Drive intersection.
During the construction of the infrastructure for the surrounding housing development in
the late 1970's, the developer [nstalled a "bubble-up" storm drain inlet at the Platino
Lane and Oro Drive intersection. Drainage from the northeast segment of the
intersection is piped into the inlet. When sufficient rainfall creates large flows within the
pipe, the pressure build-up in the "bubble-up" causes the storm water to overflow into
the drainage gutter, which then surface flows within the concrete curb and gutter on Oro
Drive until it terminates at a storm drain inlet approximately 450 feet to the south. There
is also an overflow through-curb drain which apparently was installed sometime during
the early 1990's to relieve pressure from the "bubble-up" inlet approximately 80 feet
south of the inlet. These two drainage components, combined with the already high
groundwater in the neighborhood, have created a constant trickle of water along the
gutter that creates a breeding ground for the growth of moss. This moss is not only
slippery and unsightly but creates a constant maintenance task for Public Works staff.
The current project resolves this situation through the removal of the "bubble-up" storm
drain inlet at the intersection, installation of a "French Drain" with an 18" PVC pipe
adjacent to existing curb and gutter to convey the stormwater flow between the existing
system and an existing drain inlet 450 feet south on Oro Drive. Associated work
includes the replacement of a concrete ADA ramp, sidewalk segments, and spandrel;
asphalt trench patch; and storm drain tie-ins.
ANALYSIS OF ISSUES:
On September 1, 2015, five bids were opened for the subject project. The lowest bid,
$62,412 from JG Contracting Corporation was deemed responsive and staff
recommends award of a construction contract to JG Contracting Corporation
accordingly. ,
The contract time is 30 calendar days. Work is expected to start in mid-October.
ALTERNATIVES:
The following alternatives are provided for the Council's consideration:
1. Approve staffs recommendations to award a construction contract to JG
Contracting Corporation for the subject project;
2. Do not award a construction contract to JG Contracting Corporation for the
subject project; or
3. Provide direction to staff.
