Is a Belleville address in a regulated flood area, and whose map says so?

Quinte Conservation's watershed takes in the drainage basins of the Moira, Napanee and Salmon Rivers and all of Prince Edward County, and the City of Belleville is among the 18 municipalities that appoint its Executive Board. Its Property Regulation Map is an interactive map that shows whether a property is within its regulated area, and the authority says a permit from it may be needed for work near a wetland, watercourse, steep slope or the shoreline of a lake, such as construction, site grading or fill placement. Its staff can help with questions about a property, and it says checking early is particularly helpful when buying.

The authority says its permit does not override any other permit requirements, federal, provincial or municipal, and that the local municipality is the place to ask about building permits. The City's zoning also bars accessory dwelling units from areas of flooding defined in flood plain studies and the Bay of Quinte Lake Ontario Shoreline Management Plan. A regulated-area result governs permits; it is not a forecast that a home will flood, and a home outside the mapped area can still take water through a basement. Under the Conservation Authorities Act as amended in 2026, Quinte Conservation is to join the Eastern Lake Ontario Regional Conservation Authority on 1 February 2027 or a later date set by regulation.

Conservation-authority regulated-area and flood plain checks are not currently included in our reports, so for a Belleville home the authority's own map is the place to look. The full report's water and flooding group does cover past floods seen by satellite, nearby creeks, rivers and ponds, and mapped wetlands for any Belleville address.
