Post-Construction

Runoff Control


Developing, implementing, and enforcing a program to address discharges of post-construction storm water runoff from new development and redevelopment areas. Applicable controls could include preventative actions such as protecting sensitive areas (e.g., wetlands) or the use of structural BMPs such as grassed swales or porous pavement.

Developed by the Center for Watershed Protection. No specific information on the Phase II Rules but a wide variety of good information about the affects of imperviousness on streams, stormwater BMPs, buffers, etc.

The Journal for Surface Water Quality Professionals STORMWATER
Free subscriptions available, seven issues a year published. Good information available on Phase II Rules. Many articles deal with policy.

Texas Nonpoint Source Book
A site designed to provide stormwater management to public works professionals and other interested parties in Texas and elsewhere. Good information about developing a stormwater management program from a technical, not regulatory standpoint.

Florida Department of Environmental Protection Stormwater Site

Includes links to state publications and reports

 

Water Resources Research Institute of the University of North Carolina

Contains information on water resource policies and regulations in the state as well as summaries of WRRI stormwater related research reports.

American Society of Civil Engineers Database on BMP Effectiveness Studies

"The primary purpose of this database is to report on the effectiveness of urban storm water BMPs using rigorous, scientifically valid data and information....The rigorous screening criteria that ASCE developed to evaluate all the past studies were also intended as guidelines for researchers conducting BMP effectiveness studies in the future to help ensure good quality data would be collected for the database." The National Stormwater BMP Database and search engine can be found at the following link: http://www.bmpdatabase.org/

Overall the database contains 170 structural and 28 nonstructural BMPs. Six of the 198 BMPs are in NC.
