Purpose

Corman Park is vulnerable to flooding and has suffered extensive damages from past floods with major events occurring in 2007, 2011, 2012, and 2013. Drainage catchment areas cross multiple jurisdictions however a comprehensive, regional solution has not been reached. The area continues to remain susceptible to damages during spring run off and major storm events with high levels of precipitation. The work involves acquisition of elevation data, two-dimensional hydraulic modeling and flood mapping within the Rural Municipality of Corman Park to establish the major flood levels. The main objective of the project is to delineate the flood boundary within the 'Green Network' based on a major flood level associated with a 100-year rain event and produce flood maps. Hydraulic conditions (peak flow rates, capacity, water levels) for culverts will be identified through modeling.
