Why is there a flooding issue in the Country Club Estates area? What makes it different?

The sanitary sewer system in Country Club Estates is similar to the rest of the City. However, stormwater there is managed differently because of the existing topography. Country Club Estates was constructed on property that sits at a relatively low elevation and has a high groundwater table. The area under Country Club Estates was once a waterway. In the early 1940s, the Spanish Bight, initially separating North Coronado Island from South Coronado Island, was filled to allow for military runways, housing and training facilities on North Island. Because of the low elevation and flat topography, stormwater will not naturally gravitate toward the ocean; therefore, it must be pumped to the ocean. Some minor flooding may occur.
