Good thought to use this park, Countchunkula!
Here is a design that I would love to play (and it would make this the best 9-er in Chicagoland!)
The things I like about this design are:
1) Two 2-throw holes (Par-4's)
2) Several risk/reward placement holes 1, 3, 5, 9
3) Tees are paved for all but 2 short holes (2 & 7) and one long one (6)
4) A few technical placement holes that are well suited to shorter arms (2, 3, 5, 7), a few bomber holes to reward the big arms (1, 4, 5, 9), and a few medium-long holes for the medium arms (3, 6, 8, 9)
5) Trees are strategically used for more of a wooded effect (6, 7, 8). An Errant drive could easily end up with a bogey 4
6) Flow is good. Longest walk is to tee 1, and then 4B to 5T is 190'
7) Water use is not too punitive
8) It is only 10 minutes (4 miles) from where I often work
What I do not like:
1) Hole 9 could conflict with 5's tee.
2) Hole 9 uses a Mando (for safety)
3) Hole 4 comes a little too close to the playground (200' off tee)
4) Walk from 3T to 3B conflicts with hole 2
5) There are crossing fairways.....but those will only conflict in January & February
