The drainage from the southern two units on the east side of Barium Street and 50 feet of the southernmost segmer, t of Barium Street is unclear. It may either drain to the catch basins within the development or Barium Street Onto the Willow Ridge Subdivision to the south. This should be clarified. ~ This proposed drainage plan is generally acceptable. Calculations have been submitted and wilt be reviewed to ensure that the pond volumes provide adequate capacity for water quality and rate control. A permit from the Lower Rum River Water Management Organization will be required: Pond 2 in particular may require modification to ensure that it can handle the runoff from the contiguous properties to the north, as well as the subject property. A permit will also be required from IvlnDot for the discharge of storrhwater into the Highway #47 system. Calculations will need to be prepared and submitted documenting that the amount of discharge does not exceed the predevelopment conditions. Finally all turfed areas must have a mininmm grade of 1%. A minor modification in the grade of the swale draining the back yards of the un/ts on the east side of Cobalt Street should be made to comply with this requirement. b REU N',mber: The City. has enacted a quarterly drainage utility charge that is applicable to the proposed'development. The total drainage utility charge for the proposed development is $518.70 dollars per quarter.
