Volusia Environmental Committee Urges Stricter Stormwater Regulations in Wake of Hurricane Milton’s Impact

The Volusia Environmental Committee meeting on November 6, 2024, saw a discussion on stormwater management, emphasizing the need for revised policies following the severe impacts of Hurricane Milton. The committee explored various measures, such as the proposal to ban “fill and build” in wetlands, to address the challenges posed by recent catastrophic weather events.

0:00Members discussed the importance of revising the Land Development Code to incorporate stronger measures that would protect the community against future environmental changes. One member advocated for a comprehensive approach, stating, “We need language that is about banning fill and build in wetlands,” underscoring the urgency of addressing these environmental challenges.

The committee reviewed the Best Management Practices (BMP) Matrix, focusing on minimizing directly connected impervious surfaces, critical in managing stormwater effectively. The need for stormwater from roofs to be directed into pervious areas, such as rain gardens, was emphasized to promote better filtration. Members considered alternatives like exfiltration basins for urban settings where traditional green solutions might not be feasible. There was a consensus on the necessity of a broader regulatory framework that would ensure a comprehensive understanding of current and future flooding challenges.

25:21In a discussion about stormwater treatment parks, the committee explored the inclusion of recreational amenities like playgrounds and picnic areas alongside environmental considerations. Two options for stormwater treatment were proposed: a wet pond with native vegetation and bioactive media, and a dry pond with an upland buffer of native plants. Concerns were raised about the potential for developers to minimize costs by selecting the least expensive amenity options, prompting questions about establishing a minimum size for the parks relative to the overall site size. The committee also debated whether stormwater treatment areas used for recreation should count toward open space credits, highlighting the need for clear guidelines on how these areas contribute to overall site requirements.

44:18The committee addressed the technical aspects of stormwater management, focusing on increasing the carrying capacity of detention ponds by 15%. While this measure could help manage floodwaters during a storm, it was noted that it might not address post-storm flooding effectively. There was a proposal to incorporate pre-treatment systems to improve water quality before stormwater enters a wet pond. This approach aimed to enhance nutrient removal efficiency.

1:02:58The committee’s discussions also touched on the implementation of underground retention and detention systems, which could minimize impacts to natural areas. However, members expressed skepticism about the effectiveness and maintenance of these systems, given Florida’s unique conditions. Concerns were voiced about relying solely on these methods to meet stormwater requirements, with suggestions to use them as part of a broader treatment strategy.

1:41:36One speaker criticized the standards, arguing that existing retention systems were insufficient to manage recent rainfall events. They suggested that more measures were necessary to prevent flooding, echoing the committee’s call for revised regulations.

2:14:13The committee deliberated on the efficacy of vegetated swales and rain gardens in stormwater management. While native plants are crucial, there was a call for more criteria to ensure these practices provide meaningful environmental benefits. The need for a holistic approach to stormwater management was emphasized, with suggestions to integrate multiple techniques in a “treatment train” to achieve effective outcomes.
