Stormwater Quality Facilities

Stormwater runoff from developed areas has the potential to be laced with pollutants such as suspended solids, nitrogen, phosphorous, oil, and grease.  In addition, increased stormwater runoff flows from developed areas have the potential to erode existing channels, streams, and rivers, increasing the concentration of suspended solids.  The intent of stormwater quality facilities is to reduce or remove the concentrations of these pollutants in the developed stormwater runoff. 

Regulations by state and local authorities require removal of a percentage of the increased pollutant load caused by development. There are various types of treatment structures, based on the required removal, such as wet ponds, sand filtration ponds, filter strips, wetlands, and bioretention structures.  CMA has a wealth of experience in designing stormwater quality facilities, and designs each structure to fit the project and budget specifically.  Project design also takes into account stream bank erosion prevention to help prevent stormwater quality degradation.  CMA also has experience with Low Impact Development Design techniques.
