RECOMMENDED ACTION:
Adopt Resolution No. 2010-033 approving plans and specifications and authorizing the City
Clerk to advertise for bids for the La Costa Avenue Subdrain, Project No. 3681.
ITEM EXPLANATION:
Approximately 200 feet south of Cadencia Street, the asphalt concrete pavement on La Costa Avenue
is severely deteriorated with water seeping out of the pavement, even during dry weather conditions.
A subsurface investigation has indicated that saturated subgrade soils are responsible for the loss of
structural support for the existing pavement.
This project will construct a subdrain system consisting of 6-in diameter perforated PVC pipes within
the saturated subgrade soils. The subdrain system will remove the water from the subgrade and
deposit the water in the existing storm drain in La Costa Avenue. This is an allowed discharge into the
municipal separate storm sewer system per the NPDES Permit No. CAS0108758, Section B.2.
After the subdrain system is constructed, the existing pavement will be rehabilitated with an asphalt
concrete leveling course and 1.5-inch asphalt concrete overlay.
Staff recommends approving the plans and specifications and authorizing the City Clerk to advertise
for bids for the construction of the La Costa Ave Subdrain, Project No. 3681.
ENVIRONMENTAL IMPACT:
The project is exempt from the California Environmental Quality Act (CEQA) per State CEQA
Guidelines Section 15301(b) - minor alteration of existing facilities of public utility services involving
negligible or no expansion and 15304(f) - minor trenching or backfilling.
FISCAL IMPACT:
The La Costa Avenue Subdrain Project is part of a larger Capital Improvement Program called
Miscellaneous Road Subdrains, which is a City-wide effort to fix various pavement subgrade issues.
Table 1 on the next page shows the current status of the Gas Tax funding Miscellaneous Road
Subdrains Program.
