Post Construction Storm Water Management - New Development and Redevelopment
Best Management Practices (BMPs) in this category address storm water runoff from areas of new development and redevelopment. Unlike the temporary BMPs during construction, post-construction BMPs are permanent and are used to control pollution after construction is completed. The City has implemented an ordinance to ensure that post-construction BMPs are incorporated into development projects and provide for the long-term operation and maintenance of post-construction BMPs.

Tyler's Storm Water Management Program contains four BMPs in the Post Construction Storm Water Management category including:
  • PC-1 : Post Construction Ordinance
  • PC-2 : Post Construction BMP Manual
  • PC-3 : Long Term Operation and Maintenance of BMPs
  • PC-4 : Sediment Control at City Facilities

Numerous studies have documented that storm water 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 storm water from new development is to use BMPs 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 storm water runoff and improve water quality.
