This poor condition has <br /> created a nuisance and health and safety concerns to Redwood City citizens. <br /> Therefore, the existing storm drain system needs to be eliminated or rectified. <br /> There are approximately 170 siphon/bubble-up catch basins/inlets that were <br /> constructed in street corners in various locations, which are not connected to any storm <br /> drain lines, because there are actualiy no avai;able storm drain lines along the streets. <br /> These inlets are only connected with short pipes crossing street intersections. The <br /> storm water flows by gravity from the upstream inlet to bubble-up at the downstream <br /> inlet, and continue its surface flow along the existing curb and gutter until it reaches a <br /> proper underground storm drain system. Because of this, local ponding or flooding <br /> occurs in the vicinity areas. These inlets are also storing stagnant water that creates a <br /> foul odor, and have become a health and safety concern to residents. <br /> After careful studies, the problem areas were identified and divided into seven (7) <br /> priority sections, in order to address one section at a time. <br /> This project is the first priority section area needing immediate attention among the <br /> seven identified priority areas, since it is situated in the Friendly Acres Area, which has <br /> an inadequate drainage system causing chronic flooding problems. <br /> Page 1 of 2 <br />
