Dear Eric:
We have reviewed the Site Development Plans, Revision I, for Oak Park Center as submitted by McCombs
Frank Roos Associates, Inc. on June 13, 2007. Following are our comments and /or recommendations.
Sheet C-4.01
1. The west end of the bike path is at a 3:1 slope. Flatten the slope to meet AA regulations.
Sheet C 9.01
1. It appears that the detail for the curb cut with riprap is also the detail for the rip rap in the rain
gardens. It is suggested that the title on the detail be changed to represent the rip rap at both
locations.
2. The inlet pipe for the outlet structure is submerged which will result in sediments depositing on the
bottom of the pipe. To maintain an effective open area and minimize maintenance it is
recommended that the pipe is increased from 12 inches to 18 inches.
If you have any questions or require additional information, please contact me at (651) 604-4788 or Dennis
Postler at (651) 604 -4815.
