Executive Summary
The co-permittee was well prepared and staff are very knowledgeable. Appropriate pollution prevention
and good housekeeping measures are implemented and documented.
Charlotte Mecklenburg Stormwater Services (CMSWS) leads and coordinates a comprehensive watershed-
based Phase II MS4 Program, which goes above and beyond the Phase II requirements to address local water
quality impacts and issues. The program framework and tools provide consistency and structured
regulatory compliance to the MS4s under this permit; and also coordinates with the City of Charlotte Phase I
MS4 program and requirements. CMSWS provides exceptional leadership, guidance and attention to detail
for all nine permittees. The eight co-permittees are engaged, knowledgeable and well versed in stormwater
management protocols and their specific responsibilities, as defined in an annual Work Plan. The suite of
custom and commercial program management tools, SOPs, templates and databases form the
comprehensive framework for stormwater management program asset and task management, reporting,
and assessment. This program is a shining example of how co-permittee relationships work to provide local
water quality benefits through consistent regional implementation.
