Living next to the majestic Pacific Ocean comes with a price and, in Malibu, everyone is obligated to do their part to protect the ocean and its fragile marine communities. The key to eliminating runoff is preventing water from leaving your property and flowing into the street. If water is leaving your property, the first step is to locate the water's source. The most common sources of runoff are over-irrigation, car washing, and hosing down sidewalks or driveways, but runoff can also come from broken pipes, greywater connections or pool backwash, among other things. Once the source of the runoff is determined, you can assess the best remedy for the problem.
