Clean water projects

The Clean Water Program develops new stormwater facilities and designs and implements updates to older facilities that collect and treat polluted storm runoff. These projects control stormwater flows and help:

  • Reduce pollution in our water runoff.
  • Improve water quality treatment.
  • Reduce stream erosion and protect river habitat.
  • Keep our waterways safe for recreation and other uses.

Projects vary in scope and size, but may include installing rain gardens or wetlands for improved water quality treatment, expanding water storage, modifying inlets and outlets, and repairing or replacing aging facilities. Projects are funded by clean water fees and state and federal grants.

Active project

Thomas Wetlands East

Clark County Public Works and Environmental Services will expand and reconfigure an existing storm water facility to better manage polluted storm water runoff from roads, roofs and other surfaces in the East Minnehaha neighborhood just east of DC Fisher Neighborhood Park. The project will expand and reconfigure the existing stormwater wetlands to improve water quality treatment and reduce high flows from rainstorms into the Lower Burnt Bridge Creek subwatershed.

Construction should begin in July 2014, weather and contracting permitting.  The majority of construction should be complete within several months.  Access to the construction site will be limited for safety purposes.

Construction will be followed by planting more than 7,000 native plants over the winter months that will improve the appearance of the area as well as provide habitat, including 2-foot tall trees (half deciduous and half conifers), shrubs, rushes and sedges.

A maintenance road will provide pedestrian access as part of a trail system to allow neighbors to visit the site and make additional connections to the neighborhood park.
