The City of Grande Prairie has experienced significant population growth over the past decade with a resulting increase in stormwater runoff. The Intermunicipal Development Plan between the City and the County of Grande Prairie indicates short term and long term annexation areas that will provide for growth of the City over the next 50 years. In order to plan the stormwater management for the short term annexation areas the City retained Focus Corporation to update the Drainage Master Plan for the City.
