New Development and Redevelopment

Still pondBest Management Practices (BMP's) in this category address stormwater runoff from areas of new development and redevelopment. Unlike the temporary BMP's during construction, post-construction BMP's are permanent and are used to control pollution after construction is completed. The City has implemented an ordinance to ensure that post-construction BMP's are incorporated into development projects and provide for the long-term operation and maintenance of post-construction BMP's.

Tyler's Stormwater Management Program contains four BMP's in the Post Construction Stormwater Management category including:

  • PC-1: Post Construction Ordinance
  • PC-2: Post Construction BMP Manual
  • PC-3: Long Term Operation and Maintenance of BMP's
  • PC-4: Sediment Control at City Facilities

Numerous studies have documented that stormwater runoff from developed areas can potentially contribute significant amounts of pollution to lakes and streams. The increase in impervious surfaces such as rooftops, roads, and parking lots can increase urban runoff and have a detrimental impact on aquatic ecosystems due to increased concentrations of sediment, nutrients, pesticides, road salts, heavy metals, pathogenic bacteria, and petroleum hydrocarbons. The best way to reduce the negative effects of stormwater from new development is to use BMP's to treat, store, and infiltrate runoff onsite before it can affect downstream waterbodies. Innovative site designs that reduce impervious areas and low impact development practices may be used to reduce stormwater runoff and improve water quality.
