Project Detail

Improving storm drainage, minimizing right-of-way impacts

Total Cost
$8 million
Date Completed


Due to explosive growth surrounding Roy Warren Parkway, the City of Greenville needed to quantify this roadway’s future drainage capacity and identify optimal location for drainage crossings.


The vertical profile of the roadway was raised while still maintaining accessibility with existing properties, avoiding the use of retaining walls and planning for future development. A temporary channel was designed outside of right-of-way to handle the current storm drainage flows. As developments are constructed, the temporary channel will be converted to an enclosed system to handle increased flows.


The overall design limited the amount of right-of-way the City of Greenville needed to purchase, thus saving money and time.
