Frontenac Forest Stormwater Improvements
​
To reduce flooding downstream of a 200-acre watershed, EDM designed enhancements to the existing drainage infrastructure in the Frontenac Forest Subdivision. The 3-foot wide tie-wall channel was converted to a natural, meandering channel with a 7-foot wide bottom and 2-horizontal :1-vertical side slopes. EDM used a rugged tablet to enhance GPS to collect geomorphic data on each of the four reaches.

Columbia Bottom Conservation Area
The area includes a view of the confluence of the Missouri and Mississippi rivers, over 6.5 miles of river frontage, about 800 acres of bottomland forest and a 110 acre island. Columbia Bottom Conservation Area is in north St. Louis County at the confluence of the Missouri and Mississippi Rivers, the third largest river system in the world, and the largest in North America. The Corps of Discovery, led by Meriwether Lewis and William Clark, set out from this very spot in 1804. Design of a river access, confluence viewing area platform, accessible fishing pier, boat ramps and parking lots. Five miles of hiking-biking trails and five miles of roadway facilities can be accessed by car from a five-mile paved road and bicyclists and walkers can use the five-mile limestone biking trail.
