Oklahoma Low Impact Development
Low Impact Development (LID) is a comprehensive land planning and engineering design approach with a goal of maintaining and enhancing the pre-development hydrologic regime of urban and developed watersheds. The Oklahoma Cooperative Extension Service has a goal of providing information and design aids related to low impact development that will make an impact on stormwater management in Oklahoma.
This website is continually evolving, so feel free to email Jason Vogel, Stormwater Specialist in the Biosystems and Agricultural Engineering Department, with your comments or suggestions. Thanks!
Dr. Jason Vogel throws out the first pitch at the Tulsa Drillers game on July 6
On July 6 the City of Tulsa Stormwater Quality department invited Dr. Vogel to throw out the first pitch at the Tulsa Drillers baseball game when they sponsored 'Bark in the Park' and encouraged pet owners to pick up their pet waste. It was very fun. Here is the video of the pitch. It made it to the plate!
Tulsa Partners Monthly Key Message
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 increase the frequency and severity of flooding as well as 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's Partners for A Clean Environment (PACE) has a recognition program for businesses and residences highlighting LID best practices. To become a member of PACE - LID, businesses and residences must feature one or more of the above listed LID practices and agree to maintenance the LID feature as needed. PACE - LID members receive a certificate of appreciation, window display sticker, public recognition by the Stormwater Quality public education program, and may be featured on LID/environmental education tours in Tulsa.
To learn more information about becoming a PACE - LID member contact City of Tulsa Stormwater Quality at (918) 591-4325 or email Jacob Hagen at firstname.lastname@example.orgTo learn more about LID in Tulsa and around the country visit:
