The approved CIP budget anticipated spending $1,000 in Fiscal Year 1992-93, $29,000
in 1993-94, and $3,600 for testing in 1994-95. In 1992-93, $645.50 was actually
spent, and it appears that all the testing can be done this fiscal year. Dublin has
also been allotted an additional $5,300 for a professional outside consulting firm
to perform the tests on the ability of the project to remove the parking lot
pollutants from the storm water runoff.
It is therefore necessary to appropriate an additional $9,265.50 to the 1993-94
Capital Improvement budget to complete the project. All costs will be offset by
NPDES grant money.
DESCRIPTION: The Alameda County Urban Runoff Clean Water Program
(ACURCWP) set aside $300,000 to encourage agencies to propose pilot projects to
improve the storm water quality in a cost effective way. The pervious concrete/sand
filter project for the Shannon Community Center parking lot (as shown in Exhibit 1)
was one of the pilot projects chosen to be fully funded by the ACURCWP.
Through a contract with Harris ahd Harris, which was awarded by the City Council on
Septen%ber 13, 1993, the City of Dublin Public Works Department constructed two (2)
concrete filter structures 1 1/2 feet wide by 2 feet deep. These concrete channels
were filled with filter sand and covered with 5-foot long pervious concrete covers.
The channels will act as a filter to remove some of the hazardous material from
storm water which now flows down the creek to San Francisco Bay.

Pervious concrete is a mixture of gravel and cement with air voids that allows storm
water to pass through and still allows light vehicle traffic to pass over the top.
The sand is a mixture of sand particles that are blended to filter out the heavy
metal particles found in our storm water. The sand that becomes saturated with
pollutants can later be disposed of by mixing it in with base rock for roadway
construction.
Work on Contract 93-11 has been completed according to approved plans and
specifications and to the satisfaction of the City Engineer. Staff recommends that
the City Council (1) accept work constructed under Contract 93-11 and authorize
payment of retention in the amount of $2,858 to Harris & Harris; and (2) Authorize
transfer of $9,265.50 from unallocated reserves to this project. The additional
funds will be offset by grant fund revenues.
