Overview
Hamilton's Development Application Guidelines for a Floodline Delineation Study / Hydraulic Analysis, last updated February 13, 2026, for sites with no floodplain mapping or where that mapping needs updating. The study assesses a development's effect on upstream and downstream flooding and on erosion within a floodplain. It lists the minimum contents for regulatory floodplain mapping: a terms of reference, boundary conditions, calibrated flow values, topographic data, a map of cross-sections and floodlines, and model files. It names the four conservation authorities covering Hamilton as reviewers.
