2,oning File #1330 September 13, 1988 Page 3 of 5 The areas mapped by the Soil Survey as Hamel are likely incorrect, given that by definition Hamel soil normally occurs in flatter depressions between steeper hills, and the soil survey overlay onto the topographical survey shows Hamel in areas of 6% to 16% slopes, not very likely (see Exhibit C, Soil Assuciation Diagram from Soil Survey). 3. Orono Codes do not require septic testing at the time of subdivision for lots exceeding five acres in area unless anasual site conditions are anticipated. This code requirement presumes that it is difficult to determine where houses will be located on a five -acre property, and that most lots containing five dry buildable acres have a very high likelyhood that suitable sites exist on the property. For this currently proposed subdivisi.,ii, staff would recommend that soil borings be completed by the applicant's consultant for Lots 2 and 6, both of which indicate that the f latter areas of the property are mapped as Hamel soils. Staff feels it is appropriate at this time to request this information to determine whether suitable mound sites are feasible on those two lots. Staff will work with applicant's consultant regarding the location and number of borings required. C) Future Road Extensions: Staff and the City Engineer have reviewed the development in the surrounding properties in relation to the need for future road access to the east or south. Staff and the City Engineer concur that, since the neighboring properties are generally developed to the maximum five acre density for this area, under the current zoning standards no future toad connections would be anticipated. D) Easements Required: The City will require dedication on the plat of Conservation and Flowage Easements over the wetlands occurring in Lots 2 and 3, and an Easement of a width yet to be determined along the length of Painter's Creek in Lots 2, 3, 4, and 5. Additionally, the standard 10' perimeter and roadway drainage and utility easements will be required, as well as similar easements 5' in width each side of interior lot lines.
