17-3932 August 21, 2017 Page 5 of 8 Road Layout and Standards The proposed road is depicted as being a private road. While this is consistent with the RR -113 District 2 -acre zoning, a question for discussion is whether the road system serving the proposed development should be public or private if developed as RPUD. The CMP Transportation Plan in Urban Transportation Policies states: 1. Local streets in the urban area will be owned and maintained by the City (i.e. public streets). Because the land use and street use density of the urban neighborhoods is relatively high, the City will provide public street access to all urban properties. City responsibility for proper maintenance levels will ensure passable, all-weather streets available at all times for emergency vehicles and for general public ingress and egress. At the urban density proposed, it can be argued this should be a public street. The applicants are prepared for the road system to be private. As proposed, the road system will serve only this development and has no potential to be extended to serve other neighboring properties in the future. At this sketch plan stage, road designs have yet to be established. The City's minimum paved width standard for a private road system serving the number of dwellings proposed is 28'; for a public road, the minimum paved width would be 32'. The City's standard for maximum length of a cul-de-sac road is 1000 feet. The depicted sketch plan shows a private road with cul-de-sac approximately 1500 feet in total length, not including the loop segment at the north end of the site. A variance or waiver of this requirement would be required. Waivers of the cul de sac length are not uncommon. In the current plan, curb and gutter would likely be required in order to manage stormwater for some portion of the internal road system. Street design and grading information is required at the time of preliminary plat for City Engineer and Fire Marshal review. Sight distance at the entrance to Orono Orchard Road should also be reviewed. Road Improvements and/or Easements Needed Assuming the road would be private, the City will require a Road, Drainage and Utilities Easement over the private road, which should be platted as an outlot and designed and built to City private road standards. Standard perimeter drainage and utility easements around all property boundaries as well as conservation and flowage easements over the delineated wetlands will be required. At the time of preliminary plat review, the City Engineer will determine whether any improvements to Orono Orchard Road, such as turn lanes, might be necessary. Parks, Trails, Sidewalks The property abuts the Luce Line Trail, and the sketch plan suggests a private trail connection from the Luce Line to the cul-de-sac. This connection would require some type of wetland/drainage ditch crossing structure subject to City and MCWD approval, and may require approval from the DNR. RPUD standards require that 10% of the development site be provided as a private recreation area or open space to serve the residents of the development. The site as designed would appear to have sufficient open space to meet this objective. Park Dedication In addition to the RPUD requirement for creation of a private recreation area to serve the development residents, the City Code requires dedication of 8% of the land as public park, or payment of the equivalent value in cash.
