#2239 - Sketch Plan May 16, 1997 Page 3 2. 3. 3. 4. plans submitted wth the formal application must include existing and profMDsed 2’ contours. The plans must also include the following; Erosion control. Building pad locations and elevations. - Temporar>‘ erosion control during construction. PesifeTiated Wetlands. There are no designated City or NWI-mapped wetlands within the property. The major ravine and drainageway at the northern portion of the property is not designated on the City ’s wetland inveniory maps. Utilities, This property is within the MUSA and sanitary sewer is available from either Tonkaview Lane or Wildhurst Trail. Water supply will be provided by individual private wells. Referring to Exhibit D. sanitary sewer will have to be extended approximately 300' north along Wildhurst if tliat route is used, which is probable since the sewer in Tonkaview' would likely have to be lowered to serve Lots 2, 5 and 6. The developer will bear the cost of sewer installation in addition to a per unit sewer connection charge ($7,445/unit per 1997 fee schedule) since the property has not been previously assessed for sewer Easements. The proposed road locations eliminate past concerns regarding the steepness of access to Wildhurst which would have required extensive excavation. The drainage and grading plans must address how drainage will be directed, providing storm sewer where necessa’y. In the original Heathercroft plat (of which the Soskin property is existing Lot 2), the subject property was platted with 10' drainage and utility easements along all exterior lot lines. The City w ill ask for a dedication of drainage and utility easements at 5 ’ width along all internal lot lines and 10' along the proposed road right-of-vay. The City will ask for drainage easements over all retention areas, drainageways and storm sewers. Private vs Public Roads. The Orono Comprehensive Plan encourages the development of private roads in the rural area to serve new development. In the urban area (1 acre and 1/2 acre zones) all new roads are generally expected to be public. The City does not generally encourage the development of public road cul-de-sacs due to maintenance requirements, but in this case it is staffs recommendation that both cul-de-sac roads be accepted as public upon completion. The basis for public roads here is two-fold: 1) The development is in a sewered urban area, and the cul-de-sacs are not unusually lengthy; and 2) The City needs to retain public access to the newly acquired park areas along the Garden Lane right-of-way. The new road will also have the potential to serve Lot 70, Tonkaview Gardens, which is directly south of proposed Lot 7. It has not been determined how or whether that paicel would be assessed for the road extension which would serv'e it, or whether sewer would be
