摘要

For years residents of the Los Angeles communities of Sun Valley and North Hollywood have had to endure flooded streets, sidewalks, and property on a fairly regular basis. Highly urbanized and relatively flat, the areas lack a comprehensive drainage system. As a result, floods result from even minor rainfalls, as storm water that is unable to infiltrate the many impervious surfaces rapidly inundates roads and other low-lying areas. Although the Department of Public Works (DPW) of Los Angeles County long ago made plans to install a flood drain that would rapidly convey storm-water runoff away from the watershed, funding problems prevented its construction. However, the DPW is now pursuing a radically different approach. Instead of simply building a drain to alleviate flooding in the watershed, it is developing a multifaceted plan to improve water conservation, reduce pollution from storm water, enhance wildlife habitat, and, of course, control flooding.
