Average yearly rainfall in the County of Los Angeles is 15 inches.
January, February and March are the County’s rainiest months.
The month of October typically marks the beginning of the rainy season.
Southern California has 5,000 miles of storm drain network.
Storm drains were designed to capture rainwater to avoid area flooding. Storm drains capture urban runoff water when residents over water their lawns and gardens, wash their cars in their driveways or hose anything on pavement. The water flows directly to the ocean – untreated.
Stormwater is not treated or filtered before it enters the ocean.
Storm drains dump into either Ballona Creek or the Los Angeles River, both are primary habitats for many of Los Angeles’ species of birds, animals and plants.
The County maintains two trash nets, located at Ballona Creek and the Los Angeles River, that capture tons of litter before it flows into the ocean, yet this is just a small part of the amount that flows to beaches every year.
Trash nets in Ballona Creek and the Los Angeles River capture 200 tons of litter each year.
The Los Angeles flood channel has enough trash to fill the Rose Bowl field two stories deep.
County residents dispose of enough tons of waste to fill Dodger Stadium every two weeks.
