Residents of the Country Club neighborhood (Alameda to Coronado Ave) are concerned that the storm drains always remain full to street level even during long periods with no rain. Prior to WWII, this area was a body of water, known as Spanish Bight. It was filled in with sand dredged to deepen San Diego Bay, then covered with soil and made into a golf course and horse racing track. In about 1953 it was sold to a developer who constructed some 225 homes. The continued presence of groundwater, which we fear is contaminated with hazardous chemicals buried at NASNI and residential sewage easily overwhelms the storm drain system due to its many cracks. Some 300,000 gallons sits in the system, often for several months. Solids settle to the bottom, and small amounts of liquid are pumped into the City sewer system, which travels across the Bay to San Diego and to Point Loma. On warm dry days, a certain amount evaporates from the storm drain inlets, which causes a most objectionable odor. As time passes, hydrostatic pressure keeps the system full, up to street level. The contents continue to percolate into a toxic sludge, until a “rain event” occurs and the entire collection is pumped into the Pacific Ocean via the North Beach outfall pipe we visited today.
Attached are photos of flooding which occurs at various times, either from City personnel forgetting to turn on the pumps when it rains, or from inadvertently running the pumps backwards. In other areas of the Coronado, garbage piles up along gutters until it finds its own way to the bay or ocean.
