Irondequoit, NY Environmental Rules: Flood Zones (2026)

Chapter 136 of the Town of Irondequoit Code applies to every area of special flood hazard inside the Town, in Monroe County. Section 136-6 maps those areas through FEMA Flood Insurance Rate Map panels for Community Number 360422, several with an effective date of July 31, 2024, plus a Flood Insurance Study of the same date. The maps and study are on file at the Department of Community Development in the Town Hall, 1280 Titus Avenue.

The Director of Community Development is the local administrator under § 136-11. Section 136-12 makes the permit mandatory for all construction and other development in a mapped area, and the application can require plans in duplicate, drawn to scale, showing the nature, location, dimensions and elevations of the site, structures, fill, stored materials and drainage facilities. Beyond the $25 fee, the applicant reimburses the Town for added review, inspection and approval costs, including legal fees, and the administrator can demand a deposit of no more than $500.

Section 136-13 asks for the proposed elevation of the top of the lowest floor, basement or cellar included, for any new or substantially improved structure, and an as-built elevation certified by a licensed professional engineer or surveyor once that floor is in. In Zone A with no base flood elevation data, the applicant supplies it for developments greater than either 50 lots or five acres. Altering a watercourse requires engineering computations showing equal or greater conveyance.

Under § 136-14 the administrator refuses a permit if the work would physically damage other property or fails the Article V construction standards, issues stop-work orders for development found without a permit, and withholds occupancy until a certificate of compliance issues. A substantial improvement means a cost that equals or exceeds 50% of the structure's market value before construction starts.
