Re: Stillwater Ford — Conversion Van. Center
Revised Grading & Utility Plan Review
Bonestroo File No. 55 -02 -000
Dear mss:
OWN,
DEC - 4 2002 � D
We have reviewed the revised grading and utility plan for the proposed Stillwater Ford —
Conversion Van Center as submitted by METRO Land Surveying & Engineering. As you are
aware, the owner' previously submitted improvements for this site for an Employee and Storage
Parking Lot Addition. As a result of the proposed development revisions, revised .4 grading and
utility plans were submitted to our office on November 26, 2002, and we have the following
c ornments recommen atr ons :
1. The previous grading plan (under the employee parking lot scenario) routed storm water
runoff to the southwest and -northeast corners of the parking lot, then .utilized curb cuts to
allow the storm water to enter overland drainage ditches /swales. The current revised grading
plan (under the conversion Van center scenario), proposes to route storm water runoff to the
southeast and northeast corners of the parking lot. Additionallv, the revised grading plan
calls for filling in the ditch along Neal Avenue North and installing storm sewer along the
entire frontage of the site.
2. The grading plan we received contains handwritten revisions showing three curb cuts in the
parking lot curb & gutter to allow storin water to enter drainage sw ales/depress ions, the
elimination of proposed catch basins and storm. sewer exiting the parking lot, and revisions
related to proposed storm sewer structures for the storm sewer in the filled ditch. These
hand-written revisions need to be incorporated into the drawings and the proposed contours
revised accordingly (the current contours do not correspond to the handwritten revisions).
3. Adequate riprap and/or other adequate erosion control measures should be placed at the three
proposed curb cut locations.
4. A storm sewer profile is required for the proposed storm sewer necessitated by filling in the
existing ditch. A. drainage area map and calculations are required to Verify that the proposed
size and slope of the pipe are adequate for the storm water flows in that area. Elevations for
the proposed beehive catch basin manholes need to be specified as well.

5. Another hand - written note calls for a 20" pipe connecting the existing catch basin in Neal
Avenue North to the proposed storm sewer in the ditch. 20" is an uncommon size for storm
sewer, and this should be called out as a 12" or 15" reinforced Concrete Pipe.
6. According to an email from Jay Johnson,' MnDOT has confirmed that they have issued a
permit to Denny Hecker for a Wan Conversion Center on Neal Avenue North, Additionally,
Jay's entail indicates that Brown's Creep watershed District has reviewed the revised
grading plan, and will not require a new permit for the revisions (if the hand-written
modifications are incorporated into the grading plan). We recommend the applicant submit
the final revised grading plan (incorporating the hand - written revisions) and the City receive
written , verification from B CWD indicating their acceptance of the final revised plan.
7. The 4" PVC sanitary sewer service shall be Schedule 40 pipe.
8. The 2" copper water service shall be connected to the existing mainline via a wet tap.
