As part of the development, Pond 500 would be an expansion of an existing pond that was constructed as part of the Northpointe development. Comments: 1. The applicant shall show silt fence around the perimeter of Pond 500 2. The applicant shall note that inlet protection shall be placed in existing downstream catch basins in the Northpointe development. 3. The applicant shall show the existing drainage conditions (arrows or contours) of the south side of Cedar Street. The applicant shall show the proposed drainage grades for the ditches in this area. It appears there is a high point on Lot 2, Block 1 that would prevent the drainage from flowing south to the existing pond. Note added to daylight ditch to the west. 4. The applicant shall note the use of sediment control measures is required at inlet flared end sections. 5. The applicant shall extend the silt fence/perimeter control measures to include adjacent wetlands to the bituminous trail construction to the south. 6.

The applicant should consider including wall section views/details. As discussed, wall designs will be submitted by the grading contractor 7. The applicant should consider leaving additional space around the retaining walls (away from the noise wall & wetlands) to allow space for equipment to access the wall for necessary repairs/excavations in the future. As discussed, we are unable to move the wall due to the proximity to the fence and berm. Wall material (modular) will ease future repairs. 8. The applicant shall provide the EOF for CB 104 & 107 and verify that the EOF provides 1 foot of freeboard to Block 2 Lots 8&9. EOF added at the high point at STA. 5+50.

The applicant shall provide a street sweeping plan. Sections 4.3 and 5.2 of the SWPPP notes that the street shall be cleaned within 24 hours of detection for tracked sediment. • Stormwater Management The stormwater management for the Eastside Villas development consists of catch basins at the low points to convey stormwater to Pond 500, and discharge into JD3. Comments: 1. For maintenance, the City recommends extending storm sewer through the backyards of the east side of the development versus installing multiple flared end sections that discharge into MnDOT right-of-way 2. The applicant shall label the bench around Pond 500. 3. The applicant shall note the locations of the outlet flared end sections underneath the berm on Block 1. Are these proposed to be within MnDOT right-of-way? If so, permitting will be required.
