Authorize an additional appropriation of $9,265.50 from new revenues.

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. ITEM NO. ~ COPIES TO: Harris & Harris I CITY CLERK ..... FILE 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. a:(contracts)~pervious~agstacpt Page 2 Shannon Cenf er Pervious Conc Sand R'lf er 20Hang PVC Parking Lof p¢~vieus Cone Sand ,', 35'long ' Sf 'Drain Shannon Ave. CITY OF DUBLIN ~PROVED DATE ';; ' ' bP, AW~ ':~ " PUBLIC WORKS DEPARTMENT p ERVIOUS CONCRETE SAND FILTER LOOATION EXHIBIT ~Z COUNTY OF ALAMEDA PUBLIC WORKS AGENCY 399 Elmhu~st Stxeet · Hayward, CA 94544-1395 (510) 670-5480 October 28, 1993 Mehran Sepehri Senior Civil Enginee~ City of Dublin PO Box 2340 Dublin, Ca. 94568 Dear Mr. Sepehri: Subj: Agreement Modification for Pervious Concrete Pilot Study Proposed for the City of Dublin's consideration is this agreement modification for the City Manager's execution in order for the City to continue the subject project.
