Mr. Steve Ach • December 16, 1993 Page Two The SuperAmerica site grading plan has some very steep slopes (2:1) in the northeast corner. In the southeast corner, the grading plan does not match the existing contours. This should be corrected. The grading plan shows grading in the UPA easement on the west side of the side. A permit will most likely be necessary from UPA to accomplish this work. 3. Utilities The preliminary utilities plan for Oak Parc Plaza shows an alignment for the future trunk sanitary sewer and watermain coming up the west side of the plat adjacent to Highway 169. In this area they are showing the utilities within the UPA power line easement. This is not an appropriate location. A utility easement at least 50 feet wide should be shown adjacent to the UPA power line easement. The remainder of the alignments on the south and east side of the SuperAmerica site are appropriate. The permanent trunk utilities will not be available until such time that they are brought from the west side of Highway 169. Therefore, they will not be available for the construction of the SuperAmerica site. • The SuperAmerica site utility plan shows the extension of individual services along the east side of the site and then easterly on 193rd Avenue to tie into the existing utilities in Hillside Estates Addition. The length of the sanitary sewer and water services is over 500 feet. This approach will work in the interim until trunk utilities are available; however, it does pose the problem of how to maintain service to the SuperAmerica site while the trunk utilities are being constructed, since the temporary services are on a similar alignment to the permanent services. The developers of this site should consider this and provide the City with an indication of how this might be accomplished, or an understanding that the utility services may be cut off to SuperAmerica for some period of time during construction of the trunk facilities. 4. The Elk River Municipal Utilities has indicated a need for easements on the site for providing electrical service. This issue should be coordinated with Glenn Sundeen of the Municipal Utilities. 5. The overall plan for Oak Parc Plaza proposes that storm drainage be collected and conveyed easterly to a sedimentation pond. However, the site plan for the SA facility indicates just the opposite. It shows internal storm drainage being collected and conveyed west and outletting in the highway ditch. It is not clear that this alternative would work. It appears that the overall plan for the Oak Parc Plaza is II a much better approach to the storm sewer in the area. The utility plan for the SuperAmerica site should be revised to reflect the storm sewer concept shown for the Oak Parc Plaza development.
