AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for
DeBenedetti Park (G -Basin) Storm Drain Improvements
MEETING DATE: September 2,2009
PREPARED BY: PublicWorks Director
RECOMMENDED ACTION: Approve the plans and specifications and authorize advertisement for
bids for the DeBenedetti Park (G -Basin) Storm Drain Improvements.
BACKGROUND INFORMATION: This project consists of installing approximately 870 lineal feet of
72 -inch storm drain pipe, 42 lineal feet of 42 -inch storm drain pipe,
one weir structure, three outfall structures, and other incidental and
related works, all as shown on the plans and specifications of the
project. Exhibit A provides a conceptual sketch of the proposed improvements.
This project is needed to divert storm water that currently enters the northwest playfield in order to protect
from inundation the new turf to be planted in Spring 2010. The proposed storm drain improvements will
divert storm water from the main in Century Boulevard to the main deep basin via a proposed 72 -inch
diameter pipe. As a result, the entire G -Basin watershed area will drain directly into the deep basin. The
deep basin and northwest playfield will be connected by a proposed weir structure and interconnecting
piping that will allow water to flow to the northwest playfield if the deep basin is full. A future storm drain
pump station at the northeast corner will allow the basin to be drained and will be constructed under a
separate construction contract in 2010.
Following completion of this project, a contract will be awarded in early 2010 to install irrigation, turf and
trees for the playfields at the northwest area; irrigation and erosion protection within the basin area; and
sidewalks on Century Boulevard and Lower Sacramento Road. Planting should be completed by early
Spring and the playfields should be ready for sports play by Fall 2010.
Staff is recommending that City Council approve the plans and specifications and authorize advertisement
for bids for the project. Delaying this project will require the installation of turf to also be delayed.
The plans and specifications are on file in the Public Works Department. The planned bid opening date
is September 23, 2009.
FISCAL IMPACT: The estimated project cost is $600,000. There will be a slight increase in
the long-term storm drain maintenance cost of the proposed facilities.
FUNDING AVAILABLE: Funding forthe,project is from the Storm Drain Impact Fee.
