The current 2008 New Hampshire Stormwater Manual (Manual) has been updated in response to evolving science and available technologies for stormwater management as well as new and increasing local, state and federal permit requirements. The updated 2025 Manual has been developed through a partnership between the New Hampshire Department of Environmental Services (NHDES) and the University of New Hampshire Stormwater Center (UNHSC), with consulting assistance from Comprehensive Environmental, Inc. (CEI).
Representatives from NHDES, UNHSC and CEI will outline the collaboration process with stormwater professionals, provide an overview of the 2025 Manual, and highlight the significant changes from the 2008 Manual.
The 2025 Manual and recording of the informational session can be found on the UNH Stormwater Center website.
