Press Release:

Firm Receives Individual 404 Permit For Construction Of A Regional Stormwater Detention Basin

Tuesday, August 7 , 2018


David Flick, Principal and Founder, announces that the firm successfully completed Section 404/401 Clean Water Act permitting for the City of Olathe.


Lackman Road and five residential properties abutting Heritage Park have experienced periodic flooding for many years. Various engineering studies completed the past 20 years have evaluated options to improve public safety while minimizing impacts to Coffee Creek and its adjacent riparian corridor.


To solve the problem, separate embankments south of 167th Street along the future Lindenwood and Brougham roadway alignments will serve as temporary backwater detention of Coffee Creek and its headwaters. Such volumetric detention will attenuate existing and future runoff and remove four downstream residential properties from the regulated 100-year floodplain.


Scientists with the firm assisted the client in receipt of a Section 404/401 Individual Permit from the U.S. Army Corps of Engineers and the Kansas Department of Health and Environment. The complex submittal included endangered species, cultural resource, and alternative analysis investigation covering a period of 6 months.


To replace the lost aquatic resources that result from the authorized project, the permittee must purchase credits from the Kansas River and Missouri River Wetland and Stream Umbrella Mitigation Bank, where such surface waters are preserved through perpetuity under the management by Terra Technologies.
