Stormwater Management Systems:
SB 810 would amend Florida’s stormwater inspection law to require municipal separate storm sewer system permittees, referred to in the bill as “MS4 entities,” to perform formal operation and maintenance inspections of all permitted stormwater management systems they own or operate by September 1, 2026. The bill defines “MS4” by reference to federal stormwater regulations and adds a new statutory framework for identifying infrastructure within those systems that is especially vulnerable to blockage, deterioration, failure, or other deficiencies and that could cause flooding and property damage if it fails.
The bill also requires annual inspections of any infrastructure meeting those risk criteria beginning after the initial inspection, and it directs MS4 entities to complete a stormwater facility inspection checklist developed by the Department of Environmental Protection whenever an inspection occurs. That checklist must be submitted to the department and the Division of Emergency Management by September 1, 2026, and annually thereafter as applicable, and it must identify the relevant infrastructure found during inspection. The act would take effect July 1, 2025.
SB 810 would expand section 373.423, Florida Statutes, by imposing new inspection, documentation, and reporting duties on MS4 permittees and other local stormwater system operators. It would create a statutory definition of MS4 and MS4 entity, require targeted annual inspections of high-risk stormwater infrastructure, and establish a recurring checklist submission process to state agencies. The bill would primarily affect municipalities, counties, and other permit holders responsible for stormwater management systems, while also increasing oversight by the Department of Environmental Protection and the Division of Emergency Management.
The available legislative history suggests the bill’s subject matter was viewed as important and aligned with broader stormwater and flood-mitigation policy, but the bill itself did not advance to enactment. SB 810 died on the Senate calendar, and the record notes that a companion measure passed instead as CS/CS/SB 180. That outcome suggests the policy concept had support, but the specific bill did not complete the legislative process.
The main policy issue appears to have been the burden and scope of new inspection and reporting requirements placed on MS4 permittees, especially local governments responsible for maintaining stormwater systems. The bill would have required identification of vulnerable infrastructure, annual follow-up inspections, and submission of detailed checklists to state agencies, which could raise administrative and compliance concerns. At the same time, the bill’s supporters likely emphasized flood prevention, infrastructure reliability, and emergency preparedness, particularly for systems whose failure could cause property damage.
