Keeping Our Waters Clean (Stormwater Management)

In accordance with the Federal Water Pollution Control Act, the Clark County Regional Flood Control District, as lead agency, has been operating under a National Pollutant Discharge Elimination System (NPDES) permit with the various city, county and state agencies since December 1990. The permit outlines a schedule of monitoring requirements, best management practices, and conditions designed to promote the reduction of pollutants in storm water.

This past year included execution of a Storm Water Management Plan (SWAMP) identifying specific program areas which must be addressed. A construction site inspection program was implemented and several training sessions were held for local construction companies. The inspection program is the result of an interlocal agreement with the Clark County Department of Air Quality and Environmental Management. This allows air quality inspectors to perform storm water quality inspections at construction sites along with their other duties. The inspection program will reduce the amount of sediment and construction
pollutants entering the storm drain system. The District is also an active member of the Lake Mead Water Quality Forum, the Las Vegas Wash Coordination Committee and participates on the Management Advisory Committee for the Las Vegas Wash. Annual reports of NPDES compliance activities are available on the District’s website. 

Additional information useful to the general public in the reduction of storm water pollution is available at The site provides information about storm water quality, describes proper use and disposal of chemicals and fertilizers, and educates the community about how to improve the quality of urban runoff that travels untreated to Lake Mead. Similar information is distributed at several community events throughout the year.

Residents can also help reduce the impact of pollutants on the environment. By notifying the District and the local government entities about improper disposal of chemicals and pollutants, corrective action can be taken by the appropriate agency. Clogged storm drains and washes, littered with debris, may also cause pollution and flooding problems. In the case of a severely clogged drop inlet/storm drain, residents should notify the city or county jurisdiction where the drain is located.

Last year the District developed a new public service announcement (PSA) focusing on the importance of keeping storm drains clear of clogging debris. This PSA ran on all the local network affiliates for three months in the spring and reinforced the importance of not dumping trash and reporting problems to the District. Other PSAs developed by the District focus on proper fertilizing of lawns, responsible disposal of pet waste, and the benefits of using commercial car washes. District staff also is available to give presentations to groups interested in environmental topics associated with flood control.
