One of the major projects of the club has been the City of Mequon Rotary Park which was officially launched September 17, 1987 marking the fiftieth anniversary of the club's existence. The site encompasses approximately 95 acres and is located on Highland Road near the Milwaukee Area Technical College's north campus. The Thiensville-Mequon Rotary club donated the site to the City of Mequon in 1991 and has remained actively involved in its development as a recreational resource for residents across the Thiensville-Mequon community.

In 1992, the T-M Rotary was awarded a "Significant Achievement Award" by the President of Rotary International, Rajendra K. Saboo, as a result of 5 years of effort in turning the club's vision for an active use park in the City of Mequon into a reality.  District Governor Rick Luedke was so impressed by T-M Rotary's success with City of Mequon Rotary Park that he petitioned Rotary International to present this highest honor.  Our club, and District 6270 is deeply honored by this award, as it is rarely awarded.

Since the award was presented to our club, many additional improvements have been added to the park, including 2 pavilions and the gazebo, three baseball fields and two playgrounds.
