Box 391 <br />Redwood City, CA 94064 <br />Engineers & Scientists <br />2191 East Bayshore Road <br />Suite 200 <br />Palo Alto, California 94303 <br />650 - 852 -2800 <br />FAX 650. 856.8527 <br />Subject: Proposal for Design Services for Storm Drainage Improvements to the Emerald <br />Branch of Redwood Creek at Garrett Park <br />K/J B03089 <br />Dear Jon: <br />Provided herewith is our proposal for providing the City of Redwood City with design services <br />for the improvement of the inlet conditions for the Emerald Branch of the Jefferson Branch of <br />Redwood Creek located at Garrett Park in Redwood City. Per your request, we have modified <br />our original proposal for design /build services with Power Engineering to this proposal for <br />conventional design services that are consistent with the public bidding of the improvements. <br />Our proposal is based on our understanding of your needs from discussions with you, visits to <br />the site, a review of the report by BKF Engineers on the investigation of Bain Place flooding and <br />a review of the original design drawings of the storm drainage system. <br />During past storm events the existing trash rack at the inlet to the Emerald Branch on the <br />upstream side of Garrett Park has become blocked with debris causing flooding of Garrett Park <br />and subsequent flooding of two adjacent properties on Bain Place. As indicated in the BKF <br />report, there are several improvements that can be implemented to reduce the risk of flooding in <br />the future. These improvements include: <br />- Modifying the inlet structure to increase the trash rack area and the time between <br />cleanings before flooding would occur <br />- Increasing the size or adding additional downstream inlets to the system to allow for <br />flow bypassing the trash rack to enter the storm drainage system downstream of the <br />trash rack prior to flooding downstream homes <br />- Installing a downstream barrier to divert flow that bypasses the storm drainage <br />system inlets to Glenwood Avenue, rather than through the Bain Place properties. <br />5-113-3 <br />Kennedy /Jenks Consultants <br />�paoiadminlnusdev12003VetterpmpsW30B9_ mdwoodaty yaaetlparkVewmdlederpmposal.dm <br />
