Construction sites can have a serious impact on the environment by releasing sediment from exposed surfaces to the storm drain system. Runoff with sediment can cause water bodies and storm drains to become clogged, causing high turbidity, which harms aquatic life and marine ecosystems.

All construction sites are required to implement Best Management Practices (BMPs) to prevent pollutants from impacting the storm drain system. Construction sites over one acre are required to be covered under the State Water Resources Control Board's Construction General Permit.

Some new development projects will need to comply with Water Quality Management Plans. These plans are required to be implemented for the life of the development. Information regarding Water Quality Management Plans can be found on the Engineering website.

Low Impact Development (LID)

Urbanization increases impervious surfaces, which causes more water to runoff into the storm drain system instead of percolating into the ground and recharging ground water aquifers. LID is a land planning and design approach that reduces impervious surfaces and retains or reuses storm water on the property. LID includes rain gardens, bioswales and permeable surfaces to promote infiltration.

If you witness illegal dumping of a hazardous material in a storm drain, dial 9-1-1.

To report a discharge of non-storm water to the storm drain system, after calling 9-1-1, you may call the City of Garden Grove Environmental Compliance Division during office hours at (714) 741-5956 or after office hours at (714) 741-5375. 

To report a sewer spill, please contact the Water Division during office hours at (714) 741-5395 or after office hours at (714) 741-5704.

To report a clogged storm drain please contact the Flood Control Division at (714) 741-5375.
