Updated Release of Structural BMP Prioritization and Analysis Tool (SBPAT v 1.1) Now Available

An updated version of an innovative software tool designed by Geosyntec practitioners to assist engineers in water quality analysis and the selection of stormwater best management practices (BMPs) is now available online and at no cost.

The Structural BMP Prioritization and Analysis Tool (SBPAT) is an open source, GIS-based software that facilitates the selection of BMP project opportunities and technologies for use in urban watersheds. It also helps engineers and community planners quantify the benefits, costs, uncertainties, and potential risks associated with stormwater quality projects.

Officials with the Los Angeles Regional Water Quality Control Board have approved SBPAT software for use as a peer-reviewed, public domain, and quantitative model. As such, it can be used to develop a reasonable assurance analysis (RAA) in support of a watershed management program. Water quality officials have praised the software for its ability to fill a critical technology need, especially in the design of integrated and cost-effective total maximum daily load (TMDL) implementation plans and cost allocation strategies.

The initial version of the software, SBPAT v 1.0, was developed with data specific to Los Angeles County in 2008 by Geosyntec Consultants, with direction and support from GreenInfo Network, Heal the Bay, the City of Los Angeles, and the Los Angeles County Department of Public Works. It has been used to review water quality management plans for Ballona Creek and the Los Angeles River.

The latest version of the software was developed with data specific to Orange County, California, for the Orange County Transportation Authority (OCTA). Authority officials use OC-SBPAT (SBPAT v 1.1) to support funding for water quality improvement projects proposed through the Measure M Transportation Investment Plan.

The original technical development team at Geosyntec included Ken Susilo (Los Angeles), Eric Strecker (Portland), Brandon Steets (Santa Barbara/Los Angeles), Marc Leisenring (Portland), Dan Pankani (Portland), and Aaron Poresky (Portland).

These Geosyntec practitioners are at the forefront of providing guidance to private and public sector clients on the implications of new and emerging regulations that affect stormwater management throughout the United States.
