Over Irrigation is Prohibited
Over watering to the point which the water is running into the street and the City's storm drain system is not permitted within the City of La Mesa. Please report water wasters to the City's storm water pollution prevention hotline at 619.667.1134 and to Helix Water district at https://hwd.com/report-water-waste/ .
What is Storm Water Pollution?
When it rains, water flows over parking lots, streets, yards and other surfaces collecting everything from cigarette butts to motor oil and washes them into the storm drain system. Storm drains are designed to reduce potential flooding of streets and properties when it rains but are not connected to treatment systems. Therefore, everything that is washed down a storm drain eventually ends up in lakes, rivers, creeks and, ultimately, on the beach and in the ocean.
The Pollution SolutionTo reduce storm water pollution, city staff, developers, contractors, businesses and residents are required to implement Best Management Practices (BMPs). BMPs are practices or devices used to reduce or eliminate pollutants from entering the storm water system. A BMP can be as simple as picking up after your pet, using minimal fertilizers and least toxic pest controls, or eliminating over-irrigation of your landscaping.
