NOU-22-1996 10:37 P.05/06 Mr. Steve Ach November 22, 1996 • Page Four Municipal Utilities. He has no problem with this being built in the easement as long as sufficient cover is maintained over the watermain, which appears will be the case from the Grading Plan. However, he did point out that these would built at the Holiday Company's risk. If the Utilities need to excavate this watermain, it would not be their intent to replace anything that has been built in their easement. One other issue with these parking stalls is that they are perpendicular to stalls along the north side of the building. The two corner stalls closest to each other would be very difficult to use. If the parking stalls are to be constructed like this, there should be more space provided between the most easterly on the north side of the building and the most southerly of the ones built in the watermain easement. 12. The Holiday Station Store is proposed on the site of the existing School District Administration Building. Therefore, a condition of the site plan approval should be that the existing building be removed. B. GRADING AND DRAINAGE PLAN 0 1. There is a drainage pond located on the west side of the Holiday site. The contours indicate that the pond slopes would start immediately behind the sidewalk on Freeport Avenue and end immediately behind the curb line on the Holiday site. The side slopes are shown at 3:1. We would recommend that the pond be constructed with a flat area, five to ten feet wide, behind the sidewalk on Freeport Avenue and the curb line on the Holiday parking Iot. We would also recommend that the minimum side slope of the pond be increased to 4:1. City policy has been to fence anything steeper than 4:1. We do not feel it is reasonable to have a fenced pond at this location. 2. The storm drainage for the site is being reviewed as part of the Heying Addition, which is the plat of the entire School District property. 3. A spot elevation at the northwest corner of the building is 923.15. Water is intended to flow from that location to the catch basin located in the island to the west. However, the east end of the island is shown at elevation 923.25. This elevation needs to be lowered to get the water to drain to the west. • 4. There is an outfall line from the pond to the north which flows to the pond on the Holiday site. There is also a catch basin to collect water from the curb line. These are shown as two separate lines_ We would suggest, if possible, that these two lines be combined. 2301345-2109.nov
