base_districts[*].mbnep_ccmp_coordination_role | override | non_regulatory_voluntary_partnership | Mobile Bay NEP is one of 28 National Estuary Programs under CWA §320 (33 U.S.C. §1330). The Comprehensive Conservation and Management Plan (CCMP) — currently 'The Waters We Share' — provides watershed planning guidance but does not impose federal land-use controls. |
base_districts[*].mbnep_ccmp_recommended_practices | add | ['stormwater_lid_practices', 'riparian_buffer_voluntary', 'shoreline_living_shoreline_preference'] | CCMP recommended practices may be incorporated into local zoning by ordinance — not preempting, but identifying voluntarily-adopted standards. Watershed Management Plans developed for individual sub-watersheds (Dog River, Three Mile Creek, Fowl River, Fish River, etc.) provide site-specific guidance. |

Research notes
Non-regulatory. Coordinated with ACAMP (AL_ACAMP_COASTAL_9_7_10) and ADEM §401 water quality certification. NEP watershed spans Mobile and Baldwin counties plus the upper Mobile-Tensaw Delta. Cities in the watershed (Mobile, Daphne, Fairhope, Spanish Fort, Foley, Robertsdale, Bay Minette, Saraland, Satsuma, Chickasaw, Prichard) commonly cite the CCMP in stormwater and riparian-buffer ordinances. Distinct from the Mobile Bay Keeper litigation-track NGO.
