Zoning File #1881 April 15. 1994 Page 2 Ceil Strauss has confirmed that no DNR permit will be required. The Minnehaha Creek Watershed Distrkt has tabled the application pending City approval. *The Watershed District and applicants' engineer have met to discuss the culvert sizing to ensure no impact on properties upstream. Easement Issue Resolved The outlot in which the driveway is proposed to be constructed is owned by the next door neichbor, James Lawrence, who apparently is opposed to the driveway. Because staff required Lawrence ’s signature on the application before accepting it as complete, applicants pursued and obtained a Declaratory Judgement from the Hennepin County District Court confirming that Whitmans' easement over the outlot gives them the right to construct driveway within the easement without the Lawrences approval. This is documented in Exhibit L. Proposed Grading Plan Exhibit E is a topographic review of the general area of the proposed crossing. There is a driveway culvert approximately 600’ upstream serving the end house on Tanglewood Road. The 48" culvert proposed is the same size as the culvert downstream which not only takes the flow from the Holy Name tributary but also from that leading to Long Lake from Wolsfeld Lake. The Watershed District is expected to approve the size of the culvert as proposed. City Engineer Shawn Gustafson has reviewed the site and has no problems conceptually with the plan. He did recommend to staff that the proposed 2:1 slopes on the stream crossing be constructed at a 3:1 slope. This requirement will be passed on to the Watershed District for their review. The total length of driveway to be constructed is approximately 450’ and will involve the movement of approximately 1.000 cubic yards of material. A significant portion of the stream crossing fill will likely be generated from construction of the driveway, although some importation of fill may be necessary . Conditions of Approval The Shoreland Regulations, Section 10.56, Subdivision 16 (J) provide a number of considerations and conditions ("Best Management Practices") that must be adhered to during construction projects such as that proposed: • Alterations must be designed and conducted in a manner that ensures only the smallest amount of bare ground is exposed for the shortest time possible. • Mulches or similar matenals must be used where necessary for temporary bare soil coverage and permanent vegetation cover must be established as soon as possible.
