The City of Monroe is working to protect our local waterways from the impacts of stormwater pollution. When it rains, pollutants such as sediment, fertilizer, oil, trash, and pet waste are carried by stormwater runoff into the nearest drainage system. The City maintains a Municipal Separate Storm Sewer System (MS4) that includes storm drains and other drainage structures, ditches, pipes and outlets, which discharge into creeks and lakes. Since the MS4 is not connected to a treatment system, it is critical to minimize the amount of pollutants that enter our waterways and into water supply watersheds Lake Lee and Lake Twitty.
The City of Monroe strives to maintain the storm drainage system to address roadway and offsite drainage as well as water quality. The City generally seeks to improve drainage systems and drainage ways when there are existing unsafe conditions, recurring erosion, or property damage as determined by the Engineering Department.
Stormwater Management System
The City of Monroe is required to comply with all aspects of the National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater Regulation. The City was issued its NPDES Phase II Stormwater Permit in October 2005. Under the City of Monroe’s NPDES Phase II Stormwater Permit, the City is authorized to discharge stormwater from the City’s Municipal Separate Stormwater Sewer System (MS4) located within the corporate limits. Under the permit, discharge of stormwater from point sources is authorized to receiving waters and their tributaries. As part of its ongoing effort to help protect local waterways and to meet both federal and state regulations, the City of Monroe Engineering Department has developed a comprehensive Stormwater Management Plan. The plan includes six minimum control measures to control the discharge of pollutants from the municipal storm sewer system associated with stormwater runoff and illicit discharges, including spills and illegal dumping. In addition, the City administers a Stormwater Management Ordinance to control stormwater pollutants as well as increased stormwater volume and velocity from new development and redeveloped sites so that water quality is protected and downstream flooding is reduced. The ordinance requires a Best Management Practice (BMP) for all development and redevelopment within the corporate limits and extraterritorial jurisdictions of the City of Monroe.
