Scientists Complete Complex Wetland Delineation In Missouri River Floodplain


January 6, 2014

Scientists with Terra Technologies completed a complex wetland delineation for a 14-acre former industrial site in the Quindaro Bottoms areas of Riverside Missouri.

 

A local manufacturer operated at the site since the 1970s.  Aerial photographs confirm their utilization of much of the site for the storage of manufactured materials, with a detention basin and storm water swales.  Pumps in the basin conveyed storm water to a ditch for overland conveyance.  A dyke ensured collection of all runoff.  Prior to dyke construction, runoff would flow along the railway toe in an existing swale.

 

In 2008, site demolition resulted in the discontinued use of the storm water pumps and the inability of runoff to drain from the site.  Aerial photographs confirm ponding of water at higher elevations than observed during facility operation.  As a result of this artificial hydrology, wetland conditions were observed across an extensive area.

 

Upon resumption of pump operation, it was the firm’s opinion that the true extent of wetlands was limited to the two swales draining to the basin. The perimeter extents of ponded water represent an artificial limit of hydrology. The resulting wetland area computed to 0.33 acres, much less than the observed 4.0 acres.

 

Scientists with Terra Technologies submitted findings to the Corps of Engineers who visited the site and concurred with our opinion. The client received a jurisdictional determination confirming 0.33 acres of wetlands.

 

Scientists and engineers at Terra Technologies perform greater than 100 wetland delineations annually. For more information about Wetland Delineations, contact your local office of Terra Technologies.
