Low Impact Development

What is low impact development (LID)? It is a development and engineering design approach used to maintain pre-developed or natural site hydrology under post-development conditions. LID improves both stormwater quantity and quality by managing stormwater close to the source through infiltration, evaporation, and storage.

Some examples of LID are:

  • Permeable Concrete
  • Permeable Pavers
  • Rain Garden/Bioretention
  • Vegetated Bioswale
  • Green Roof
  • Rainwater Harvesting

Why is LID important? Studies have shown that when the percent of impervious surface, (roads, sidewalks, parking lots, rooftops) in a watershed reaches the 10-20% range the stream is no longer able to function healthily, and the stream becomes impaired. In highly impervious watersheds, pollutants enter streams in higher concentrations and at faster rates compared to natural watersheds. Impervious surfaces also speed up the flow of stormwater runoff and cause erosion.

Tulsa's stormwater quality permit requires water quality standards to be maintained and the promotion of LID in development is one way to maintain stream health.

 

LID slows the flow of stormwater runoff, and allows it to soak into the ground, thereby removing harmful pollutants from entering our streams lakes and rivers.

The City of Tulsa recognizes the following individuals, groups and businesses that have incorporated LID into their building design:
