1. Rather than removing the existing hydrant near the lift station it could be relocated a few feet east of the new parking lot.
Having the hydrant near the lift station is useful for maintenance. The hydrant SE of Bldg "A" could be used but would be a
private hydrant. It would be better to use a City owned hydrant and we would not have to stretch fire hoses across the
parking lot.
2. A new turn around area for the lift station needs to be designed and shown. More detail on the grading near the lift
station is required to show water flow to the beehive manhole inlet (which is not shown on the drawing either).
3. The area is shown to be serviced by four new fire hydrants. The new hydrant near the SW corner of Bldg. "C" is located
such that the line leading to it will have two storm water crossings and one sanitary sewer crossing. The other three
hydrants are within 300 feet of each building. If this hydrant were removed and Bldgs "B" & "C" were feed from the north
end of the building we would avoid the crossing of the water main with sewers, reduce the total amount of water main to be
installed, decrease hydrants and valves by one and have better water flow to the buildings as each building will have its
own 6 inch line coming from the 8 inch loop. I am assuming that each of these buildings are going to have fire sprinklers.
Of course the fire marshal will need to review and comment on the adequacy of the remaining three hydrants to
cover fire fighting needs for the four buildings.
3. Where storm sewers cross over the top of water mains, insulation should be installed between the storm sewer and the
water main.
4 Where sanitary sewer cross water mains the top of the sewer must be 12 inches below the bottom of the water main.
5. Sanitary sewer for Bldg. "D" must be a minimum of 50 feet away from McCormack's well.
6. More temporary construction entrances will be needed if more than one bldg. is built at a time. Currently, the Kohl's
contractor is ignoring the erosion control entrances.
I think these are most of my comments. I think Dennis will mention increasing the width of the outbound lane onto 60th to
24 feet for 2 lanes.
