In 1982, HRC developed a Master Storm Drainage Plan for the City of Farmington Hills designed to guide them during the continued development of the City.  As a result of record flooding along the Grand River corridor including serious property damage at the Red Roof Inn and two local automobile dealerships, HRC was selected as the consultant.

The Master Plan focused on the use of existing natural open drainage system to its fullest, and ultimately utilized a combination of open drains, enclosures, on-site retention ponds and municipal retention basins to accommodate storm flows safely through the City.

Several prioritized alternatives were established to address the immediate existing flooding problems as well as future anticipated flooding problems.  Each alternative worked together to develop an overall Master Plan.  Cost estimates were prepared for each priority.

The two flood relief projects that were recently constructed were the Minnow Pond Drain and the Cadell Drain.  Both of these projects provided relief from overland flooding that was being experienced within their districts.
