Stormwater Management and Flooding

Why does Volusia County experience flooding?

Volusia County experiences flooding due to a combination of recent high-than-average rainfall levels, extreme weather events, saturated ground tables, and properties located in areas that are not up to current code standards. The county has seen an increase in excessive rainfall events, which can overwhelm stormwater systems, especially in low-lying areas and regions with limited drainage outlets. Additionally, areas developed before modern stormwater regulations may have inadequate drainage infrastructure, increasing the risk of flooding.

Is Volusia County responsible for stormwater management in all areas?

No, Volusia County is responsible for stormwater management, drainage maintenance, and flood mitigation efforts only in unincorporated areas of the county. Incorporated cities and towns manage their own stormwater systems and regulations, so residents within city limits should contact their local government for stormwater-related concerns. However, Volusia County does maintain Mosquito Control Open-Channel Canals and canals along county-maintained roads within incorporated areas to help ensure proper water flow and flood prevention. Additionally, the county works with municipalities on regional flood mitigation efforts, particularly when projects and funding extend across multiple jurisdictions.

What is the difference between stormwater management and flood mitigation?

Stormwater management focuses on handling day-to-day rainwater runoff through a network of pipes, retention ponds, and drainage systems to prevent minor flooding. Flood mitigation, however, involves long-term strategies such as infrastructure upgrades, property buyouts, and land-use planning to reduce the risk of severe flooding events. Both work together to minimize water accumulation and protect properties.

How do I know if my property is in a flood zone?

FEMA creates and maintains flood zone maps that classify areas based on their risk levels. Property owners can check their flood zone designation using FEMA’s Flood Map Service Center or contact Volusia County’s Stormwater & Flooding Division for guidance on flood risk and insurance requirements.

How does the county maintain stormwater drainage systems?

Volusia County inspects canals, clears vegetation, and removes debris from storm drains and retention ponds to ensure proper water flow in excess of nationally recommended standards. Maintenance is performed regularly in unincorporated areas, while cities are responsible for their own stormwater systems. These proactive efforts help reduce blockages and improve drainage capacity during storms.

What are stormwater retention ponds, and who is responsible for maintaining them?

Retention ponds capture and store stormwater runoff, allowing it to gradually drain or be absorbed. Publicly maintained ponds in unincorporated areas fall under the county’s jurisdiction, while private retention ponds—such as those in HOA communities—must be maintained by the property owners or HOA. Proper maintenance is essential to prevent flooding and preserve water quality.

What steps can homeowners take to reduce flood risks?

Homeowners can protect their property by elevating structures, improving drainage, installing flood barriers, and maintaining gutters and storm drains. Properties in high-risk flood zones that have experienced repetitive flooding may also be eligible for buyout programs or other mitigation efforts. Taking proactive measures can significantly reduce potential flood damage.

What should I do if my neighborhood experiences flooding after heavy rain?

If flooding occurs, residents in unincorporated areas should report drainage issues to Volusia County’s Public Works Department for assessment. In HOA communities, privately maintained stormwater ponds should be inspected to ensure they are functioning correctly. While the county works to maintain public drainage systems, extreme weather events may temporarily exceed system capacity.

How does the county determine which flood mitigation projects to prioritize?

Flood mitigation projects are selected based on watershed studies, engineering models, historical flood data, and available funding. Each project must go through assessment, permitting, land acquisition, and construction, meaning large-scale efforts take time to complete. The county prioritizes projects that offer the greatest flood protection impact.

The county can only approve of and conduct studies in unincorporated areas.

What major flood mitigation projects have been completed recently?

Since 2019, Volusia County has completed multiple drainage improvements, retention pond expansions, and water quality enhancement projects, including Rio Way, Thornby Park, and the Gabordy Canal. These projects help reduce flooding risks and improve stormwater management. A list of these projects is available on this website.

How is the county funding new flood mitigation projects?

Many projects are funded through federal recovery programs, such as the Community Development Block Grant - Disaster Recovery (CDBG-DR) and the American Rescue Plan Act (ARPA). These funds support infrastructure improvements, floodproofing, and stormwater system upgrades to increase community resilience. A list of in progress and recently approved projects may be found on this website.

What actions has the County Council taken to address flooding?

The Volusia County Council has approved multiple flood mitigation efforts, including stronger development regulations, enhanced canal maintenance programs, and increased funding for flood mitigation projects. Additionally, the council has directed staff to explore seven key flood resilience initiatives to further protect the county from future storms.

How does the county respond to flooding during major storms?

The county conducts emergency canal and drainage protocols, deploys pumps, and coordinates with emergency management teams to manage stormwater levels before, during, and after an event. Strategic pump placements help prevent road and property flooding, while crews remain on standby for post-storm cleanup and drainage restoration.

Why does the county focus on keeping water out of homes rather than preventing water buildup on roads and yards?

The primary goal of flood mitigation, not just in Volusia County but across the nation, is to prevent water from entering habitable structures, as this poses the greatest risk to public safety and property damage. While standing water in yards and streets can be an inconvenience, it is often a necessary part of stormwater management. Systems are designed to drain water in a controlled manner, prioritizing the protection of homes and businesses.
