Belmont enjoys a Mediterranean climate with long seasons of dry sunny weather, but winter storms do routinely produce torrential downpours, altering natural drainage flow patterns which can cause soil erosion and flooding that damages land, buildings and other property.
Stormwater is water that originates during rainfall events and does not soak into the ground and becomes surface runoff. There are two areas of concern for stormwater runoff:
- Construction Sites
Construction sites that do not have erosion control measures in place hold the risk for soil, silt, hazardous waste and other pollutants to be carried into stormdrain system and discharge into the San Francisco bay.
- Poor drainage
During heavy downpours, stormwater can cause flooding due to lack of proper drainage around the home.
