Medinah Country Club (MCC) hired renowned golf course architect Tom Doak of Renaissance Golf Design, Inc. to develop the renovation of Course #1, which first opened in 1925. Doak prepared a master renovation plan that included the rerouting of several holes. Working closely with MCC Director of Golf Course Operations Curtis Tyrrell and his staff, CBBEL developed a plan for an updated drainage network that addressed existing drainage issues on Course #1 and the adjacent Course #2. The drainage improvements included new main drainpipes and nine dry stormwater basins strategically placed to blend into the course design.

In response to severe streambank erosion at Meacham Creek, which flows north to south through Course #1, CBBEL developed an aesthetically pleasing streambank toe treatment consisting of natural river boulders and native vegetation. Additionally, an existing online weir that created a pond along Meacham Creek was removed and a new weir and bridge were constructed at a different location to accommodate the rerouting of the 17th hole along the creek.

Permits from DuPage County, IDNR-OWR, and USACE were obtained and the construction started October 1, 2012, one day after the conclusion of the 2012 Ryder Cup. Course #1 reopened to membership play during June 2014.
