Why Your County Needs Floodgates

Installing floodgates can benefit communities that sit upstream

Upstream communities can lie in high-risk flood zones from rising tides and storm surge. One way to reduce this risk: installing floodgates.



The Takeaway

Floodgates protect communities from major storm events, and allow them to release stormwater more safely for a moderate cost in building and maintenance. Coastal communities on harbors and bays, and inland communities that sit upstream and experience tidal flooding and storm surge will benefit from these gates.

  • How they work: Floodgates lessen flooding upstream by holding back excess water from events like high tides and storm surges. The gates then open when it is safe, allowing water to resume flowing normally.

  • Why you need them: Farm and residential landowners benefit from the ability to prevent river overflow and disperse built-up water at the most opportune time. 

  • Why your county needs them: Areas with expensive buildings and infrastructure along a harbor or bay can benefit from the protection from strong waves and storm surge that floodgates provide. Relative to other flood protection measures, floodgates come with a moderate price tag to the county and taxpayer. They also have long average lifespans, ranging from 25 and 50 years.

Take action: Both coastal communities and inland communities near rivers, streams, or canals may be able to fight their flood problem with strategically placed and operated floodgates. Let your local commissioner know that floodgates are worth the investment.

  • Yes, but: Elected officials might push back on the cost of maintenance as flooding continues to worsen, but their long lifespan can make the cost worthwhile.
