The City of Daly City and The City and County of San Francisco have jointly prepared the Vista Grande Watershed Plan. The plan outlines a program to enhance flood protection in the Vista Grande watershed (northwest Daly City), reduce erosion along Lake Merced, and enhance habitat and water level in the lake.
