Stormwater Master Plan

The purpose of this document is to update the current and dated Stormwater Master Plan (adopted by the City Commission in February of 1989) and identify a range of macro scale drainage improvements for construction required to address existing system deficiencies and serve the city as it grows.  We encourage the residents of Great Falls who witness any flooding to please report the location and attach pictures, if available, to any emails you submit.  If there are question to the document itself, please reference the page number and/or exhibit number in your submission.  The Great Falls International Airport owns and maintains its own stormwater system and the basin surrounding the airport was not included in this study.
