The City of Modesto’s Municipal Stormwater Permit requires that Priority New Development and Significant Redevelopment projects integrate Low Impact Development (LID) strategies and use a combination of Stormwater Volume Retention and Treatment Control Measures to retain and treat the first half-inch post-project Stormwater runoff volume for the purpose of water quality. Plans must be submitted and undergo a review to ensure the plans conform to City Municipal Code, Standard Specifications, and the City’s approved and adopted 2011 Revised Guidance Manual for Development Stormwater Quality Control Measures.
