HR Green Wins ACEC-IA Award for Fort Madison, Iowa Dry Creek Stream project

Hr Green, Inc.

HR Green is pleased to announce it has received an ACEC-IA  2016 Engineering Excellence Award for its Dry Creek Stream Improvements project in Fort Madison, Iowa. Dry Creek is a tributary to the Mississippi River located in the eastern part of Lee County, Iowa.

“It is exciting to be recognized for our work by our fellow engineers,” said Aaron Gwinnup, PE, “We were privileged to work with Fort Madison to stabilize this stream and restore the local ecosystem for the benefit of the entire community.”

Following damage sustained during high flow events in the spring of 2013 The City of Fort Madison, Iowa hired HR Green to investigate stream conditions and provide designs for remediation. HR Green staff assessed the Dry Creek channel and riparian corridor and the assessment was used to identify opportunities for in-stream improvements to enhance aesthetics, natural habitat and water quality.  Once preliminary designs were developed to address the stream restoration goals, HR Green conducted public outreach, hydraulic modeling, final design, permitting, bidding assistance, and construction administration for the project.

A major goal of the project was to restore the waterway to being a natural, enjoyable neighborhood amenity instead of a degraded drainage channel. HR Green provided remediation measures to stabilize the banks for the long-term, gently lowering the stream profile through a series of pools and rock riffles, adjusting the stream cross-section to better convey both low and high flows, and providing rock and native vegetation for bank stabilization.

HR Green also assisted the City in applying for Clean Water State Revolving Fund Sponsored Project funding and FEMA Disaster Public Assistance funding. Both applications were successful, allowing the City to proceed with channel restoration design and construction.
