Engineering Comments: <br />1. <br />2. <br />3. <br />The plan before the City Council is the first to propose a pressure sewer system. Pressure <br />systems are usually only used when gravit)’ does not work and/or the sewer is being provided <br />to a developed neighborhood. The Cit>- Engineer has recommended a gravity system be <br />used. The gravity system is appropriate for a new development. There is also less concern <br />for long term maintenance. <br />Due to public health and safety issues it would be appropriate for the Cit>‘ of Orono to <br />require water service to the property. Many of the lots within the development are smaller <br />than the standard RR-IB two acre lot with a 200' minimum width and 30’ required side yard <br />setback. Lots less than 1 acre in size will have a side yard setback requirement of 10’. There <br />is the potential of locating residential structures with only 20 ’ of spacing. The concern would <br />be fire possibly spreading fi:om one property to another. Municipal water would also allow <br />hydrants to be located along Willow Drive and within the development. <br />The grading plan is for the most part acceptable. The City Engineer has recommended the <br />lowest basement elevations be above the Normal High Level of the ponds and the exposed <br />opening 2' higher the High Water Level of the ponds. <br />Public/Private Road: <br />The Comprehensive Plan states Private Roads shall have a maximum service of approximately ten <br />residential properties. Private roads shall be privately owned and maintained by a Homeowners <br />Association. The City will require that private roads be constructed and maintained to Ciw <br />standards. The City will acquire an easement for public ingress, egress and access to all properties. <br />A public road would require the developer to build the road to City standards. Located within the <br />road right-of-way would be public utilities (sewer, water, telephone, gas and/or cable service). The <br />Comprehensive Plan indicates the proposed roadway be a public road. The basis would be the road <br />not being located within the rural area (sewer and water service is available) and the roadway would <br />serve 25 individual lots. <br />Another alternative has suggested only one access to Willow Drive and a second, future access <br />platted through the south end of the development to Kelley Parkway with the expectation being the <br />road would be extended to Kelley at the time the property to the south develops. The <br />Comprehensive Plan addresses the issue of routing non-residential traffic through residential <br />neighborhoods. The properties along Highway 12 would be serviced by the extension of Kelley <br />Parkway. If the proposed development had access to Kelley Parkway, traffic from commercial uses <br />and the City Offices would have the option to pass through the residential neighborhood to access <br />County Road 6. <br />Lot Layout and Standards: <br />Most of the larger lots within the proposed Willow View addition are located to the southwest <br />portion of the property'. Many smaller lots are located along County Road 6 and Willow Drive <br />North. The Planning Commission has recommended approval of the site plan, but Staff did have <br />concerns with the smaller lots being located closer to the 2 acre residential de\ elopment existing <br />around the proposed Willow View.
