Martin County rule: Stuart does not have its own ordinance for stormwater management. The rule below comes from Martin County and applies to Stuart.

Summary

Martin County enforces Stormwater Management and Flood Protection Standards as part of its Land Development Regulations. Development projects must provide on-site stormwater treatment and attenuation meeting both county and South Florida Water Management District (SFWMD) criteria.

Full Breakdown

Martin County's Stormwater Management and Flood Protection Standards (published by the Engineering Department) set design criteria for new development and substantial redevelopment. Standards include water-quality treatment of the first 1 inch (or 2.5 inches over impervious area, whichever is greater), peak-attenuation to pre-development discharge rates for the 25-year/72-hour storm event, and minimum finished-floor elevations above the 100-year flood. Projects also require SFWMD Environmental Resource Permits where applicable under Fla. Stat. ch. 373. Illicit discharges to the county's MS4 (municipal separate storm sewer system) are prohibited under the county's NPDES program.

Violations & Fines

Illicit discharges and non-compliance with stormwater requirements are enforced by Code Enforcement and the Engineering Department. Penalties include stop-work orders, civil fines through the Code Enforcement Board, and required corrective construction. Repeat violations of NPDES requirements may trigger EPA referral.

Frequently Asked Questions

Do I need a stormwater permit for my home addition?

Single-family home additions typically do not trigger a stand-alone stormwater permit but must comply with the county's grading and drainage rules. New subdivisions and commercial sites must meet the full design standards.

Where can I report storm drain pollution?

Contact Martin County Engineering or Code Enforcement; under the county's NPDES MS4 program, illicit discharges (paint, oil, chemicals) into storm drains are prohibited.
