Access The City Engineer has commented (Exhibit E) the proposed access to the property be platted as part of the subdivision and not by easement. Further, he recommends that the access to the site should meet a minimum 50' width to meet City roadway standards for a public or private street. The grades are a concern regarding driveway access to several lots on the property. It appears that existing grades exceed 40% on Lots 2, 3 and 7. Driveway design on these Lots will be critical as the City recommends that driveway grades not exceed 10%. Access to Lot 7 across Outlot B will require the construction of a bridge or culverts at the stream crossing. The plans should provide a design for this crossmg. Outlot B would be a shared driveway in favor of Lots 6 and 7. The drive would be required to cross Long Lake Creek which is a protected tributary stream and subject to Orono's Shoreland Management regulations. A variance would be required to allow a driveway to cross the creek. Driveway locations and proposed grading shall be shown on the survey. Drainage and Ponding The draft version of the City's Comprehensive Stormwater Management Plan shows that the site lies within the Tanager Lake drainage district. The ponding location is shown on the preliminary survey. Final grading plans should include final pond grading including a 10: 1 aquatic bench 10-feet wide at the pond normal water level. The outlet structures shall be provided on the final plans indicating the location and actual size of the pond. The City Engineer will require Best Management Practices in all areas where storm water can not be treated by the NURP pond. A drainage area map, storm sewer and ponding calculations should be provided for review by the City Engineer prior to further review. Sanitary Sewer A MUSA amendment is required to allow sanitary sewer service to the property. Sewer service has been discussed and a feasibility report has been completed for the Fox Ridge neighborhood south of the Luce Line Trail. The report identified a pressure sewer system as the most feasible to serve the neighborhood. The pressure sewer would be routed up South Brown Road to an existing gravity sewer on Watertown Road. This system would have the potential to serve properties north of Fox Ridge and south of #2550 Charles Van Eeckhout 120 Brown Road South Subdivision 11/15199 page--4
