-254- Site Plan Review: Orchard Hills Page 3 of 5 December 1, 2000 Revised January 3, 2001 the existing pond to the south which ultimately out[ets to the Rum River via 149~' Ave storm sewer. The drainage from the southern two units on the east side of Barium Street and 50 feet of the southernmost segment of Barium Street is unclear. [t 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, o This.proposed drainage plan is generally acceptable. Calculations have been submitted and will be reviewed to ensure.that the pond volumes provide adequate capacity for water quality and rate. control.. A permit from the Lo.wet R~urn Ri-ver .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 MnDot~ for the discharge of stormwater 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 alt turfed areas must have a minimum grade of 1%. A minor modification in the grade of the swale draining the back yards of the units on the east side of Cobalt Street should be made to comply with this requirement. REU Number: 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 [s $518.70 dollars per quarter. This equates to approximately a $12.35 drainage charge per unit that the owners will be responsible for. 9. Landsc. aping: The landscaping plan meets City standards. 10.
