Lai*, D, L. Shoemaker, AND J. Riverson. FRAMEWORK FOR PLACEMENT OF BMP/LID IN URBAN WATERSHEDS. Presented at TMDL 2005, WEF Specialty Conference, Philadelphia, PA, June 26 - 29, 2005.

Impact/Purpose:

To inform the public.

Description:

To assist stormwater management professionals in planning for BMP/LID implementation, the U.S. Environmental Protection Agency (USEPA) has funded the development of a decision support system for selection and placement of BMP/LID at strategic locations in urban watersheds. The BMP/LID assessment tool, based on sound science and engineering, will help develop, evaluate, select, and place BMP/LID options based on cost and effectiveness. The system is called the Integrated Stormwater Management Decision Support Framework (ISMDSF).

The initial phase of this framework development is expected to be completed in 2005 to include a comprehensive design with all pieces in place but not all functionalities. The subsequent phase will include an enhanced GIS capability for visualization of placement options, more powerful post-processors, expanded cost estimating functions, improved BMP simulation processes, and more importantly, a cost-optimization component. This presentation will be a follow-up of the paper presented at the TMDL 2003 conference. The earlier presentation focused on the project background, rationale, approach, and review
findings of watershed and BMP models. This presentation will focus on the actual design of the framework and a demonstration of its functionalities.

The presentation will also include BMP/LID modeling concepts and process formulations that can be potentially incorporated into the stand-alone BMP/LID simulation module in the ISMDSF. There is currently a confusing array of options for analyzing hydrologic regimes and planning for BMP/LID. Integrating available BMP and LID processes into one model is highly desirable.
