Program details

How it works

Boston’s flood retrofit page is a city service that explains how to retrofit a home or business to better protect it from flooding. The page is not a city grant or rebate; it is a guidance page.

What the service covers

The city says planned changes should comply with National Flood Insurance Program requirements and local building codes, and cannot redirect water onto another property. It also notes that for buildings in FEMA’s Special Flood Hazard Area with a Standard Flood Insurance Policy and substantial or repetitive flood damage, homeowners should check with their flood insurance provider about Increased Cost of Compliance coverage.

Amounts and matching

The page itself does not provide city funding. It states that Increased Cost of Compliance coverage may be up to $30,000.

How to apply

The page is informational and directs residents to evaluate retrofit options and to contact their flood insurance provider when applicable.

Timing and deadlines

No open/closed deadline is stated on the page.
