HR Green Selected to Study, Design and Implement O’Fallon, Missouri’s 2016 Storm Water Improvement Projects
HR Green has been selected to study, design and implement five projects as part of the City of O’Fallon, Missouri’s 2016 Storm Water Improvement Projects.
In recent years, municipalities in St. Charles County have been subjected to a steady increase in the amount of stormwater runoff that must be collected and conveyed. The result has been an increase in yard and street flooding with ancillary impacts including erosion, structure damage, and the flooding of basements and garages. In O’Fallon, stormwater runoff is generally collected in the streets, roadside ditches, backyard swales, and in an intermittent system of piped inlets discharging to urbanized drainage channels.
“We are excited that O’Fallon has selected us to partner with them to solve several of their highest priority stormwater management challenges,” said Project Manager Josiah Holst. “We enjoy working with many communities that are facing these kinds of issues on a daily basis, and it’s very satisfying to improve quality of life and property values for their citizens.”
HR Green will complete detailed hydraulic modeling, conceptual designs, and final designs for five separate project areas within the City. The initial tasks focus on data gathering and developing an understanding of the project sites. Input will be gathered from residents in the area who have witnessed firsthand past flood events and progressive erosion. Detailed hydraulic modeling of the existing infrastructure will be performed to ascertain performance characteristics and identify or confirm deficiencies. Working with the City, HR Green will then identify practical infrastructure improvements aimed at alleviating the issues.
