Oklahoma Low Impact Development
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!

Tulsa Partners Monthly Key MessageThe OSU LID Program is currently partnering with Tulsa Partners, Inc. to share monthly messages about stormwater and resiliency. May's Key Message is Get a Building Permit When Constructing in Flood-prone Areas.
The City of Tulsa's permitting process is designed to ensure that all construction in Tulsa is safe. A permit is required for all new construction and, most of the time, you must obtain a permit for repairing or replacing existing features. Before you begin construction or add on to your existing building, find out which permits are required by contacting the Permit Center or by calling the City of Tulsa Customer Care Center at 918-596-2100.
In addition to regular building permits, special regulations apply to construction in floodways and the Regulatory Floodplain. No construction, including filling, is allowed in the mapped floodway without an engineering analysis that shows the project will not increase flood damage elsewhere. Any activity outside the floodplain but within a natural or man-made watercourse also requires a permit.
A floodplain watershed development permit must be obtained from the City of Tulsa before commencing construction, landfill, or excavation in the floodplain. New buildings in the floodplain must be protected from flood damage so our building code requires that new buildings be elevated at least one foot above the elevation of the City of Tulsa Regulatory Floodplain.
Homeowners who are planning substantial improvements should contact the Permit & Licensing Center for a residential building permit. Elevation or floodproofing may be required if you want to construct a substantial improvement (the cost of the improvement or add-on is 50 percent of the value of the existing building). Permits also are required for a repair if it's more than just cleanup after a storm. If your property is substantially damaged (50 percent of the value of the building), federal regulations may require you to elevate or floodproof before you can rebuild.
To report illegal floodplain development or to verify that proper construction permits have been issued for a project, contact the City of Tulsa Customer Care Center at 918-596-2100. An inspector will investigate.

If you would like your LID implementation in the database, email Jason Vogel with your site description, location (latitude and longitude), type of LID practice, date of project completion and a photo. The database does not work well on Internet Explorer, but works very well using Firefox, Google Chrome, or Safari.
