Columbia Bottom Conservation Area
St. Louis County, MO
Although this is an older project (designed 2002), it remains one of our favorites, and for good reason. Did you know that the observation platform at the confluence of the Missouri and Mississippi Rivers marks the starting point of the Corps of Engineers 1804 expedition, headed by Meriwether Lewis and William Clark? Or that the Missouri/Mississippi River system is the third largest in the world, and THE largest in North America? And 60 percent of all North American bird species use the Mississippi River as a travel corridor on their northern migration routes? Makes you want to do a look-see, doesn’t it? And it’s in our backyard.
St. Louis County’s Missouri Department of Conservation chose EDM to provide civil engineering and to design public access areas, where visitors could enjoy the area and have access to the confluence from all perspectives.
Our work consisted of designing a river access, confluence viewing area platform, accessible fishing pier, boat ramps and parking lots, design of five miles of hiking-biking trails and five miles of roadway facilities (all designed ADA compliant). The paved overlook structure can be accessed by car from a five-mile paved road and bicyclists and walkers can use the five-mile limestone biking trail.
EDM provided site design engineering, full-time resident construction inspection, and project management of a team including hydrologic engineers, landscape architects, architects, fishing consultants and geotechnical engineers. This project was awarded the ASCE St. Louis Section 2003 Outstanding Civil Engineering Achievement Award.
"The Missouri Department of Conservation appreciates the professional manner in which the project challenges were handled and would recommend the services of EDM Incorporated to fulfill your engineering needs.”
