Re;:-=: "--P tter' s Commercial
Dear -Bea-rd--Members
Engineers, Surveyors 8.
Landscape Architects
As requested, we have reviewed the preliminary plat of Potter's
Commercial Park and offer the following comments:
1. Potter's Commercial Park is a proposed 16 acre development
consisting of four commercial lots.
• 2. All the lots meet the minimum lot depth and width requirement
of 150 feet and the miniatnn lot size of one acre.
3. A soils investigation as well as percolation tests should be
provided to determine the suitability of soils .for on-site
sewage disposal systems. Based on the Wright County SCS Soil
Survey, the soils consist of Glencoe silty clay loam, Cordova
and Webster silty clay loams, Dundas and Ames silt loams, and
Hayden loam. Glencoe, Cordova and Webster silty clay loams
along with Dundas and Ames silt loams are unsuitable for soil
absorption systems. Hayden loam may be suitable for soil
absorption systems if the percolation rate is greater than 60
minutes per inch.
4. In review of the grading and drainage plan, the plan shows
filling up to elevation 950 with a minimum building floor
elevation of 952.0. The water level is shown at approximately
948. Based on the sewage disposal standards, no soil
absorption system shall be installed in an area where the
water table is at any time less than six and one-half (6-1/2)
feet below ground level. Therefore, the ground should be
filled to an elevation of '54.5. ~/¢v ~ ~~.~~-~-'

5. U.S. Army Corps of Engineers and DNR permits will be required
for filling of the wetland. We would recommend drainage
easement cover the entire Outlot A.

6. It is our understanding that the existing 18 inch the drain
line is not functioning properly. This line should be
repaired and the costs assessed to the benefiting property
owners.
7. The proposed plat does not show any park dedication.
Therefore, the plat will be subject to cash payment in lieu
of park dedication.
We recommend approval of the plat subject to the items discussed
in this letter.
