A recent University of Florida IFAS survey highlights a fundamental issue in stormwater management: the people responsible for maintaining these systems often do not understand how they work.

Stormwater ponds are designed to serve two primary functions—flood control and pollutant removal. While most homeowners recognize the flood control role (70%), far fewer understand the water quality function (37%), and only 28% correctly identified both together.

This knowledge gap has real consequences. In practice, stormwater systems rely on informed decision-making at the local level—particularly in HOA-managed communities where maintenance, landscaping, and operational choices directly affect performance.

The problem is not the design of the infrastructure. It is the disconnect between system complexity and stakeholder understanding. As stormwater requirements become more performance-based and outcomes-driven, this gap becomes more consequential.

The more effective approach is to shift from passive infrastructure to actively managed systems with measurable performance. That includes real-time monitoring, professionalized operations, and clear accountability for nutrient reduction outcomes.

In short, the survey reinforces a broader trend: stormwater compliance is no longer just an engineering problem—it is an operational and management problem.

Governor DeSantis has just signed SB 848 into law, marking the first major statutory update to Florida’s stormwater treatment framework since adoption of the 2024 rule.

The bill does not change the underlying performance standards. Those remain in the Environmental Resource Permitting (ERP) program. What SB 848 does is clarify and reinforce how those standards can be met in practice.

The key issue the Legislature addressed is straightforward: how should stormwater treatment obligations be satisfied when they can be performed more efficiently at a regional scale?

SB 848 answers that question by formalizing and expanding the role of off-site, compensating stormwater treatment.

First, the bill defines and authorizes Regional Stormwater Management Systems (RSMS) as a mechanism to generate and transfer pollutant reduction “allocations.” These allocations can be purchased and used by permit applicants within a defined drainage area to meet water quality requirements.

Second, the bill confirms that Water Quality Enhancement Areas (WQEA) are also a valid compliance pathway. Enhancement credits generated by these systems can be used to meet ERP performance standards, and the responsibility for long-term treatment performance transfers with the credit.

Taken together, these provisions reinforce a broader shift already underway in the rule: stormwater compliance is now performance-based and location-flexible. Treatment is no longer constrained to the project site if equivalent or better outcomes can be achieved elsewhere in the same hydrologic system.

At the same time, SB 848 introduces guardrails.

The bill requires clear definition of service areas (typically at the HUC-12 level for RSMS), establishes financial assurance requirements for regional systems, and limits the use of certain credits in specific contexts, such as non-qualified seaport projects. The practical effect is a more structured and enforceable framework for regional treatment.

The problem with the prior system was not a lack of authority. Off-site compensating treatment has existed in ERP rules for years. The problem was inconsistency—how these tools were interpreted, permitted, and applied across projects. This results in uncertainty for developers, engineers, and regulators.

SB 848 reduces that uncertainty. It aligns statutory language with the current rule framework and confirms that regional treatment is not an exception—it is a standard compliance pathway.

In practice, this shifts how projects will be designed and permitted.

Engineers will need to evaluate regional treatment alongside onsite systems at the outset of project design. Regulators will need to apply a consistent framework for reviewing allocations and credits. And project sponsors will need to account for lifecycle cost, long-term operations, and receiving-water constraints when selecting compliance strategies.

The more effective approach is not to default to traditional onsite ponds. It is to evaluate all available tools—onsite treatment, compensating treatment, and regional systems—and select the combination that delivers the required nutrient reduction with the best long-term outcome.

That is the system SB 848 reinforces.
