Terra Technologies has successfully completed design, permitting, and construction of a bioengineered stream improvement project for the City of Blue Springs, Missouri. Scientists and engineers designed the project to integrate grade control and bank stabilization measures to protect a segment of improved trail through Ward Park.
In order to stabilize a braided segment of stream, a low water crossing was rehabilitated to allow base ecological flow through subsurface pipe culverts. Additionally, a Newberry riffle constructed with local angular rock was incorporated in a stream segment to alleviate an existing streambed headcut. Overbank deficiencies in channel geometry were corrected through grade manipulation above and beyond the stream’s ordinary high water mark. And a short segment of gabion retaining wall was constructed to provide stability to an adjacent section of streamway trail.
The project received Nationwide Permit verification from the US Army Corps of Engineers and the Missouri Department of Natural Resources in October 2010. Construction was initiated and completed within 5 days.
