CC - Item 4H - Staff Report Engineering Proposal – Storm Drain Improvements in Grand Ave . 7).-;" Ay4staf if meg teport TO: HONORABLE MAYOR AND MEMBERS ROSEMEAD CITY COUNCIL FROM: FRANK G. TRIPEPI, CITY MANAGER .7 DATE: OCTOBER 6, 1998 RE: ENGINEERING PROPOSAL -STORM DRAIN IMPROVEMENTS IN GRAND AVENUE Attached for your consideration is an engineering proposal from Willdan Associates for engineering design, design and construction survey, utility coordination, contract administration, construction observation, and federal labor compliance services for storm drain improvements in Grand Avenue from Rubio Wash to Walnut Grove Avenue. The proposed storm drain system will collect surface water runoff generated north of Grand Avenue and will join the existing storm drain in Grand Avenue at Rubio Wash. The drainage improvements will include installation of catch basins along the alignment to collect storm runoff. Upon construction completion of the project, the storm drain system will be transferred as a Miscellaneous Transfer Drain (MTD) to the Los Angeles County Flood Control District for operation and maintenance. The total construction cost for the project is estimated to be $225,000 and the estimated contract period is 25-working days. The proposed project is currently programmed in the City's Fiscal Year 1998-99 budget, where the funds are allocated for non-construction related activities. The projects construction costs and the Federal labor compliance fee will be funded in Fiscal Year 1999-2000 by Community Development Block Grant (CDBG) funds; other project costs will utilize Gas Tax funds. Construction of the project is anticipated to occur in Summer 1999.
