Stormwater Management

Protecting Your Property 
Flood damage prevention has been a responsibility of the City of McAlester since the Oklahoma State Legislature required local governmental units to adopt regulations designed to minimize flood losses. The City of McAlester’s participation in the National Flood Insurance Program (NFIP) gives the City regulatory jurisdiction over flood hazard areas of the City to promote public health, safety, and general welfare. This is accomplished by minimizing public and private losses due to flood conditions in specific areas identified in the Flood Insurance Rate Map (FIRM) which is provided by the Federal Emergency Management Agency (FEMA).

More information can be found in the City of McAlester Land Development Code which is chapter 62, article V, division four, “Flood Hazard Overlay District and Flood Damage Prevention,” of the City’s Code of Ordinances.

Preventing Pollution 

The Stormwater Pollution Prevention Division was created when the City of McAlester, like other communities in Oklahoma, was required by federal environmental regulations to implement a stormwater management program. The City is permitted through the Oklahoma Department of Environmental Quality (ODEQ).

Stormwater, also called surface water, originates from rainfall and other precipitation that runs off surfaces such as: rooftops, streets, parking lots, lawns, and other compacted surfaces such as gravel and dirt. Surface water can also originate from sources such as springs, shallow groundwater, irrigation, and car washing. Stormwater will eventually find its way into constructed drainage facilities, streams, rivers, lakes, wetlands, and groundwater.

Management of all the resources listed above is critical. Stormwater management also refers to management of constructed facilities that handle stormwater before it reaches natural water bodies. These facilities are designed to offer conveyance of water away from impervious surfaces to avoid flooding and detention of water to reduce erosion downstream and to remove or restrict pollutants before they reach natural water bodies.

If you see something other than storm water that has been disposed of or dumped into storm sewer or local water way, please contact the Public Works Department at (918) 423-9300 ext. 4990.  Someone will investigate.  Remember, storm drains are for rain.
