Zoning File #1668 August 16, 1991 Page 3 of 4 Staff has enclosed a preliminary report by the Watershed District of an original drainage plan submitted by the engineering department. This plan would have involved the excavation of portions adjacent to the wetland involving excavations to the 1016 elevation. As the MCWD report notes, all forms of retention must be above the 1018 elevation that will require berming of areas above the 1018 to approximately 1019 to 1019.5. The City is at the stage of preliminary discussions with the MCWD in order to determine the best means to provide adequate retention on-site and yet satisfy water quality concerns. The City's interest will, of course, be to minimize the impact on dry buildable land needed for development purposes. In any case, if excavations are proposed within the desginated wetland area or within 26' of the designated wetland, a separate conditional use permit and variance will be filed by the City of Orono once development plans are finalized. Once again, review Exhibit D. Note the retention area to the northwest of the property and the invert along the west lot line of Lot 1, Block 1. Drainage comes from major portions of the school at the west. Drainage from the north comes along the road from a small watershed on the east side of Old Crystal Bay Road. Drainage at the northwest seems to be retained in the lov/, wet area. Drainage from the school appears to fan out until it finally reaches the lower elevations of the designated wetland at 1018. These drainageways will be addressed with the final drainage and grading plans for the municipal facility. dation To approve the preliminary 2-lot plat of the City of Orono of Lot 2, Block 1, Willow Properties Addition finding all standards of the RR-IB zoning district have been satisfied.
