16-3819 Aprif 13,2016 Page 5 of 6 Stormwater and Drainage Improvements � Fees Creation of a new road,homes, driveways and other impervious surfaces will require stormwater management measwes, likely including creation of stormwater conveyance and storage systems. Ponding areas will require the establishment of easements and the ponding areas will not be creditable as dry buildable area. Stormwater management will be subject to City and MCWD review and approval. The property and each proposed lot aze within Tier 1 of the Stormwater Overlay District, subj ect to a maximtun hardcover per lot of 25%. The property will be subject to the Stormwater and Drainage Trunk (SW&DT') Fee. The Trunk Fee established in the 2016 Fee Schedule for 1-acre zoning districts is $5,250 per acre for each new lot being created, with a fee cap of 1.0 acre per new lot. Per Section 14-2$4, if the e�sting residence is intended to remain (on Lot 3}, only Lots 1 and 2 would be subject to the SW&DT Fee; if the home on Lot 3 is intended to be removed, it would also be sub}ect to the Fe,�. Therefore, the total SW&DT Fee will be either$10,500 ar 515,750. Utility Locations/Availability/Assessments/Connection Fees Municipal sewer is available to serve development at this site. The property was assessed for 2 sewer units and 280 feet of frontage as part of the 1973 sewer project. Far the proposed subdivision, no additional footage chatge would be required, but a third sewer unit at the 2016 Connection Charge rate of$11,316 wouid be due upon final piat approval, (Note: this is the reduced rate corrected in 2013 to account for projects which were originaily assessed based partially on units and partially on frontage). The existing sewer connection for the house on Lot 3 runs across proposed Lots 1 and 2 alang the shoreline. Leaving it as-is will require establishment of easements between the properties. Adding sewer stubs to serve Lots 1 and 2 is likely necessary, and may be difficult, as the existing gravity line is approximately 15-20 feet below existing grade. An engineered design for these connections may be necessary. Municipal water is not available and not planned to be extended to this azea of Orono. Private wells will be required. � Wetlands on Site and/or Impacted The property contains a narrow strip of delinea.ted wetland along the northerly shoreline, which would presumably remain untouched. The MCWD-required wetland buffers would Iikely be coincident with and protected by the City's 75' lakeshore setback requirements and hardcover/land alteratian limitations. The City will require a Conserv�tion and Flowage Easement over this strip of wetlands. Due to the need for vehicular access for municipal sewer maintenance (discussed elsewhere in this memo) the City will likely require that buffer widths and locations be estabiished in a manner that will accommodate such maintenance. Tree andlor Woodland Impacts The site is relatively open, with the only significant wooded azea being the steep slope (bluff} azea directly downhill from the proposed building site on Lot 1. As this wooded area is primarily within the 75' setback zone and a portion may be within a bluff andlor bluff impact zone, only minimal clearing would 1� allowed per Shoreland �rd�inance Sectians 78-1285. The developer is encouraged to preserve existing vegetation to the extent possible. It is likely that connection to the municipal sewer along the shore will require some disruption to the wooded area.
