Here are some general comments /thoughts, for today's 10:30 a.m. staff review meeting, on the latest plans I
picked up last night:
1. They're back to one driveway entrance? This is preferred over the two entrances previously proposed.
2. The parking stalls appear substandard (9' wide by 17.5' long). What is the City minimum standard?
3. The overall parking layout width appears inadequate (17.5' stalls with a 22' drive aisle).
4. The drive aisle in the northwest corner, where it narrows due to the 10' setback, appears to be Tess than 19'
wide.
5. Are the new garage accesses for trash enclosures (don't see them anywhere else on site now)? If so, they'll
probably be o.k. -- have to roll out bins. If not, trucks do not have room to back up /into these areas.
6. Several Drainage and Grading comments:
O Recommend no roof drains be allowed tributary to the DDD LLC pond.
® The internal courtyard grass drainage swale appears Tess than 1%. Recommend minimum of 2 %.
They also are proposed to drain across the sidewalks?
O There are 4 proposed drainage curb cuts with rip rap. The one to the north /northeast will concentrate
flows down the pond slope past the existing outlet structure - -- potential erosion issues. Recommend
draining parking lot to northeast corner, then collecting with a catch basin and pipe to CB #2.
• The proposed storm sewer outlet to the Kern Center Pond is in MnDOT right -of -way (City drainage
easement).
a. Probably need MnDOT approval.
b. Verify the proposed FES elevation (should equal Kern Center Pond NWL).
c. Specify how much rip rap at FES.
d. Recommend moving the outlet pipe to CB #1 (redesign storm sewer to go from CB #2 to CB
#1) to move this inlet to pond farther from existing outlet to pond --- better water quality.
® Need BCWD approval /permit.
7. The final plans needs a permanent Erosion and Sediment Control Plan.
