Marana enforces stormwater management requirements under its MS4 NPDES permit and the Land Development Code. New development must include retention/detention basins, and post-development runoff must not exceed pre-development levels.
The Town of Marana holds a Municipal Separate Storm Sewer System (MS4) permit under the National Pollutant Discharge Elimination System (NPDES) program and is responsible for stormwater quality. The Land Development Code requires new development to incorporate stormwater retention and detention facilities. Post-development stormwater runoff must not exceed pre-development flow rates for design storm events. The Marana floodplain ordinance (Title 17, Chapter 10) works alongside Pima County Regional Flood Control District regulations. Low Impact Development (LID) techniques including permeable pavement, vegetated swales, and rainwater harvesting are encouraged. Construction sites disturbing one acre or more must obtain ADEQ Construction General Permit coverage and implement a Stormwater Pollution Prevention Plan (SWPPP). Illegal discharge to storm drains is prohibited.
SWPPP non-compliance: ADEQ enforcement with fines up to $25,000/day. Illegal discharge: town code enforcement and potential ADEQ referral.
