FILE # LA20-30 August 17, 2020 Page 5 of 6 provide for the protect maintenance of the road. Utilities Stormwater management. The storm water management plan has not been approved by the watershed district or the city engineer, though their comments are provided as Exhibit H. At the time of final plat, a stormwater trunk fee will apply. Staff recommends any approval of the preliminary plat be conditioned on approval of the Watershed district and reflect city engineer comments. Sanitary Sewer. The city engineer has provided comment specific to the sanitary sewer system proposed to run within the right-of-way for the new road, connecting to a ne manhole in Orono Orchard Road. These comments are: 1. The utility plan should include profiles. For the gravity sewer main proposed, if possible the slopes of the pipes from MH 4-MH1 should be increased. 2. The connection point for the Sewer system into the MCES line must be reviewed and approved by MCES as a condition of preliminary plat approval. 3. A sewer extension permit will need to be approved by MCES and MPCA, as a condition of preliminary plat approval. Stormwater Quality. Stormwater Quality Overlay District prescribes stormwater quality standards, a maximum amount of hardcover on a given lot. The subject parcel is in Tier 1, due to its proximity to Long Lake Creek. Upon subdivision, each lot will be assigned a Tier. These assignments have not been completed. It is anticipated that lots 1, 3, 4, and 5 will be Tier 1 (25%) and lot 2 may be Tier 2 (30%). Tier assignments will be made as part of the final plat. All lots proposed are greater than 2.0 acres and are exempt from the structural coverage limitation. Parks. The plan does not include any park area. Park dedication will be satisfied by a cash donation for the 4 new lots. Landscaping. The applicant has not yet provided a landscaping plan. The subdivision code does require one shade tree per 40 feet of right of way. Staff recommends the trees be planted in clumps, a more natural effect rather than in a linear pattern. The plan anticipates the removal of two trees for road construction, and potentially 10 more. The plan does not show or identify the trees that would be removed for house, septic, or driveway construction. The trees that are to be removed are already dead, or small, 9 inches (diameter at breast height, DBH). The trees in danger range in size between 12 inches and 45 inches (DBH) and are a mixture of pine, cedar, and fir. Fees.
