Stormwater Rates & Information

A Village-wide stormwater system installation project was completed in 1996, alleviating chronic flooding problems after even short-intensity rainstorms. The segments of three residential streets that did not receive the stormwater system in 1996 received them in 2006. 

Ongoing maintenance is critical to the performance of the every stormwater system. Without regular maintenance, the system will eventually fail due to buildup and structural issues. Routine upkeep can prevent costly rehabilitative and restorative repairs. The Village maintains stormwater system (catch basins, manholes and stormwater pipes) at 100% per year. 

Clearly marked inlet drains are visible throughout the Village in the swales bordering streets. Residents are asked to: 

  • Help keep inlets free of clogging yard debris. 
  • Pick up after your pet; pet waste can add harmful bacteria to our water (all the inlets drain to the bay) that can make it unsafe to swim or play in. 
  • Check your car for leaking fluids and recycle your motor oil. Improper disposal of used oil, which includes oil leaking from cars, contributes significantly to stormwater pollution. 
  • Do not pour any hazardous liquids into the openings, as they drain directly to the bay. 

Each year, the Village of Key Biscayne collects a stormwater fee. As of 2021*, that fee is paid once a year and appears as a line item on the tax bill.

*The Village previously utilized Miami-Dade County’s Water & Sewer Department (WASD) as its billing agent to bill and collect the stormwater fee through the water bill. By adding the stormwater fee to the tax bill, the Village can streamline the payment process for residents and ensure timely collection.
