Storm Water Management Program

Storm Water Management

Natrona County is required by the Wyoming Department of Environmental Quality and the EPA to develop, implement, and enforce a storm water management program, the goal of which is to protect Wyoming's and the nation's water quality. Therefore, we have adopted Resolution 68-12 (PDF) to satisfy this requirement.

What is Storm Water?

Once the rain falls from the sky, it runs off from impervious surfaces such as roads, parking lots, and rooftops as well as from previous surfaces including lawns and fields. Runoff is commonly referred to as storm water.

Most storm water run off in Natrona County ends up in the North Platte River through outfalls from Garden Creek, Wolf Creek, Elkhorn Creek, Sage Creek, Eastdale Creek, Squaw Creek or Claude Creek. When storm water runs off impervious surfaces, it carries with it soil and pollutants, which eventually affect the health of Natrona County and our waterways.

Storm Water Issues

Storm water issues fall into two general categories, quality and quantity. As storm water flows over surfaces, it picks up chemicals and pollutants including oils and greases, fertilizers, pesticides, and sediment. These pollutants eventually end up in our lakes, ponds and streams, often resulting in degradation of these resources.

What is Storm Water Resolution?

The Storm Water Resolution will serve as an essential component to a comprehensive Storm Water Management Program. The primary goal is to protect public health and safety by regulating storm water runoff from land development projects, construction activities, soil and steam channel erosion and nonpoint source pollution associated with storm water runoff. The resolution will meet the following objectives:
  • Protect the integrity of watersheds and preserve the health of water resources by stabilizing decision making processes for development.
  • Minimize increases in runoff from development to reduce flooding, siltation and erosion to maintain the integrity of streams and channels.
  • Improve water quality by minimizing increase in nonpoint source pollution caused by storm water runoff from development.
  • Establish design and review criteria for the construction, function and use of structural storm water Best Management Practices (BMP's) to meet post development storm water management standards.
