I stopped by to figure this place out, here are my observations.
Unlike all the other KC Metro parks this one is being built from the ground up and will be a large sports complex with softball, baseball, soccer and disc golf and an indoor community center. .
The legacy disc golf course is in the north end of the park, google Legacy park lees summit.
Notes taken: Asphalt bike/walk trail
Concrete tee pads
Could not tell the layout as it needed brush clearing at the time I was there
2 nice covered pavilions
Parking lot with lighting
The parks maintenance is next door, which is a good thing.
