Guidance Documents

(June 2015)
The Municipal Stormwater Program Effectiveness Assessment Guidance document is an evolving document. As municipalities complete annual program assessments, additional data will become available that will assist in verifying links between program-wide best management practices implementation, pollutant load reduction, and eventual receiving water quality improvements.

(April 2015)
The CASQA Program Effectiveness Assessment and Improvement Plan (PEAIP) Framework provides a recommended structure and approach for the PEAIPs that is consistent with the Phase II Permit and the CASQA guidance document, ‘A Strategic Approach to Planning for and Assessing the Effectiveness of Stormwater Programs (February 2015).’ The Framework is intended to provide statewide consistency for the traditional and non-traditional MS4 PEAIPs and a customizable, user-friendly format for agencies to use as they develop their individual documents. The Framework is also recommended for consideration by Phase I MS4 stormwater programs as they consider effectiveness assessments within the context of their programs.
