Volusia Environmental Committee Tackles Flooding Challenges with New Data and Policy Proposals

The Volusia Environmental Committee meeting focused on the need for improved flood management strategies, emphasizing the rising threat of extreme rainfall and the necessity of updating local policies to mitigate future risks. Key topics of discussion included the integration of advanced flood modeling data, the revision of stormwater ordinances, and the potential impacts of legislative changes on infrastructure planning.

0:17The meeting featured a detailed presentation by J Feldon from the East Central Florida Regional Planning Council, outlining a project supported by a $1.5 million grant obtained in 2022. This project aims to address the implications of future extreme rainfall on local jurisdictions, driven by the Resilient Florida Act. Feldon highlighted a significant gap in understanding between inland and coastal flooding risks, particularly in light of recent hurricanes. The project uses sophisticated modeling techniques to predict future storm events, with projections indicating an increase in rainfall from 12 inches to 17 inches by 2040 and 19 inches by 2070 during a 100-year storm event. The data raises concerns over current preparedness levels and building regulations, prompting discussions on whether county-level policies should be adjusted to accommodate these new projections.

26:37A discussion ensued regarding the integration of flood modeling data into flood maps and regulatory tools. Participants discussed the validity of the models used, with some expressing caution over altering defined rainfall values due to potential legal challenges. Instead, an alternative method of selecting different storm events from a precompiled list was suggested. There was also a call to update the county’s outdated soil survey, which is 50 years old, to enhance resilience in development practices. The conversation extended to the integration of sea-level rise data with rainfall predictions, recognizing it as a future goal for modeling efforts.

45:25As the meeting progressed, the complexities of land use regulation came under scrutiny. Historical data on wetlands was deemed outdated, and the need for more accurate ground-truthing methods was emphasized. The ongoing county flood studies were noted as potentially refining existing models for hydrology and hydraulics, which could lead to changes in FEMA flood maps and influence insurance requirements for property owners. One participant suggested consulting the National Oceanic and Atmospheric Administration (NOAA) for updates, as their last update was over a decade ago.

1:21:08The meeting also included public comments, with a noticeable shift in sentiment regarding the moratorium and proposed ordinance changes. A point of contention was the “L” initiative, criticized for its omnibus nature and perceived lack of effectiveness in addressing flooding issues. An engineer highlighted the disconnect between the initiative’s guidelines and real-world outcomes, advocating for targeted flood studies and actions, such as property buyouts in flood-prone areas.

1:03:47The committee’s advisory role was questioned, particularly regarding the council’s ability to amend proposed ordinances. It was clarified that changes would require re-advertisement and additional readings before adoption. Discussions also touched on the procedural aspects of relaying feedback and recommendations to the County Council, with emphasis on maintaining transparency and open communication.

2:58:08The session culminated in the acknowledgment of the need for a case study approach to evaluate flooding standards. Participants debated the adequacy of current regulations and whether stricter enforcement or revised standards were necessary.
