Steve Ach • October 15, 1993 Page Three 6. There is a pond along the entire southern property line between this development and the School District property. Consideration should be given to providing a fence along the ponding area between the pond and the School District property. 7. The main access off of Jackson Avenue for service vehicles to the proposed Wal-Mart store has a driveway opening which exceeds the City standard of 30 feet. However, this may be necessary to facilitate the turning movements of large commercial vehicles. It should also be noted that this driveway has a grade in excess of 4%. Consideration should be given to lessening this grade if at all possible for ease of access during the winter months. 8. There is a low area shown on the grading plan on the Dickenson property which is Exception #2 to the preliminary plat. No attempt has been made to pick up drainage in this area. Consideration should be given to providing a storm water inlet in this area to pick up any runoff that accumulates there. 10. There is an existing 100 foot wide U.P.A. easement running through Block 2 and Outlot A. This existing easement runs through the middle of the proposed III Sedimentation Pond #3 which is proposed to be constructed in Outlot A. Due to the fact that the proposed pond is to be constructed in an outlot, it is likely that the City would end up with ownership of this particular pond. That raises the question of whether it is appropriate to have these types of utilities under the storm drainage pond because of the potential maintenance problems associated between the two. 13. The grading plan shows cuts up to 12 feet over the U.P.A. easement alignment. There are no indications as to how to avoid conflicts between the grading plan and the location of utilities within this easement. This item needs to be addressed. C. STORM DRAINAGE PLAN 1. The majority of storm drainage from the proposed development is shown to flow easterly under TH 169 to an existing ponding area on the east side of the highway. The amount of storm drainage proposed to flow into this pond will cause a rise in the water level of between 2 and 3 feet. Negative comments were received relative to this increase in water level as part of the E.A.W. The City has recently completed development of a Draft Comprehensive Storm II/ Drainage Plan. One of the recommendations of the plan was to provide an outlet to this large ponding area on the east side of TH 169 with the outlet ultimately flowing to the Mississippi River. The City is currently working on the preliminary design of this outlet, cost estimates, and funding scenarios. 152-1501.00T
