CBEP's Stormwater Committee, which comprises state and federal government agencies, municipalities, non-profit organizaitons, the Cumberland County Soil and Water Conservation District (CCSWCD), Maine Nonpoint Education for Municipal Officials (NEMO), and others, provides  leadership for CBEP's stormwater-related work.

The Committee identifies priorities and approves projects funded directly by the committee and through the Stormwater and Low Impact Development Technical Assistance Grants Program.  Typically, the committee meets twice annually: once to set priorities for the coming year, and a second time to review progress and make any needed implementation decisions.
