This project provides for the design of the storm drain improvements in the River Falls neighborhood to reduce the risk of flooding. The area is between Brickyard Road to the west and north, and MacArthur Boulevard to the west and south. The storm drain improvements will provide increased capacity at strategic locations. This project will also include bioretention storm water management facilities for water quality improvements.

Preliminary engineering was initiated in FY24 under the Storm Drain General CIP (No. 500320). Final design will be initiated in FY25 and completed in FY26.

The design of the storm water management facilities will consider implementation costs for improvements to the existing storm drain to a 10-year storm design capacity. In addition, the design will investigate additional mitigation opportunities to reduce the risk of flooding to existing structure. The order of magnitude construction cost for the storm drains improvements to meet the 10-year design standard is $8 million. Once mitigation options are identified then a construction cost will be prepared.

A pedestrian impact analysis will be performed during design or is in progress.
