Long Term Stormwater Comprehensive Plan Project (LTSWCP)

The Long Term Stormwater Comprehensive Plan (LTSWCP) is designed to develop an overall storm water management approach for the City’s stormwater infrastructure while meeting unfunded mandated NPDES permit requirements.  The plan will assist the City in Municipal Separate Storm Sewer System (MS4) compliance while also serving as a guide for short and long term planning and budgeting for stormwater system BMP’s, mitigation projects, controls, construction, maintenance, commercial and private maintenance agreements, and addressing flooding issues.

There are two major components of the City’s stormwater program.  The first component is focused on water quality and the control of storm water pollution in order to remain compliant with Federal and State mandates of the NPDES requirements of the Clean Water Act of 1972.  The second component is the management of the quantity of storm water in the system.  The City’s stormwater infrastructure is predominantly combined in most of the densely populated commercial areas. The city regulates discharges in these and other areas to ensure downstream impacts and combined sewer overflow events (CSO’s) are minimized. This entails creating regulatory oversight of all construction while creating routine inspections of storm water structures, clearing blockages, fielding citizen requests/complaints, and designing infrastructure improvements.

The Comprehensive plan, in conjunction with the Geographic Information System (GIS) data and systems that are developed as part of the plan, will provide the City with the digital infrastructure necessary to perform storm sewer system analysis to solve many storm water related quality and quantity issues while creating enterprise efficiencies.  Phase One of this project began in mid 2011 and will continue through seven phases.

Habitat For Humanity Rain Garden

The Storm Water Department and the City of Charleston is committed to improving storm water in our watershed. Rain garden and streetscape improvements have already help improve storm water. These projects reduce nutrients, sediments and other pollutants entering the City’s waterways through the use of infiltration and vegetative and soil filtering.

Projects around the City

  • Habitat for Humanity’s Rain Garden (805 Young Street)– This Rain garden infiltrates the storm water from the parking lot eliminating the need for a storm drain. See pictures at: http://hfhkp.org/restore/RainGarden.html
  • West Virginia Department of Environmental Protection Rain Garden (601 57th Street S.E.) This rain garden catches water from the parking area, infiltrates and filters it before returning the water to the ground table.
  • Florida Street Streetscape, (2nd Avenue to Kanawha Blvd). Reconstruction of new curb and sidewall incorporated “drains to waterways” inlets to help educated the public on storm water.
