The proposed improvements create a parkin lot on the west side of Neal Avenue North ill front of the Pon Express Auto Wash. Access is proposed via one new drivewa to Neal Avenue North sli south of the propert center. The drivewa would be better located sli north of the propert center, unless future development considerations (buildin location, traffic flow) ne this. 2. Pedestrian access from this parkin lot to Stillwater Ford's main buildin lot will need to be addressed (pathwa pedestrian crossin on Neal Avenue N., etc. Parkin Lot Improvements: I We recommend that the parkin lot pavement section be a minimum of 3" bituminous pavement on 6" a base, assumin deliver trucks will not be accessin this area (no t section shown on the plans 4. The t of concrete curb & g utter proposed borderin the proposed parkin lot should be shown on the plans. Gradin 5. Gradin for the proposed parkin lot is desi to route storm water runoff to the west and cast corners of the parkin lot, then utilize curb cuts to allow the storm water to enter draina ditches. Ade riprap should be placed at the four proposed curb, cut locations, and at the downstream end of the proposed drivewa culvert. 2335 West Hi 36 av St. Paul, MN 55113 n 651-636-4600 w Fax: 651-636-1311 6. The proposed parkin area is located ri up to the existin draina and utilit easement encompassin the westerl ditch of Neal Avenue North. As such, proposed g radin g will fill in the ditch with 3:1 slopes on its westerl side. North of the proposed drivewa the affect of this g radin g /fi I lin is minimal. South of the proposed drivewa however, g radin g will fill in the ditch bottom to a point where it is almost 2' above the culvert elevation. The ditch bottom needs to be maintained (or even lowered sli to allow positive draina from the proposed drivewa culvert to the existin ear wash drivewa culvert. 7. The proposed curb cuts in the westerl comer of the parkin lot drain to a small depression. It appears that this area is then to drain to the east (to the Neal Avenue North ditch) alon the north side of the car wash drivewa However, the proposed contours are not clear (not well enou defined) how this will occur.
