PUBLIC INVESTMENT IN INFRASTRUaURE The public road network established in Roseville Cornerstones should provide for circulation through and within the Cornerstone intersections, but it also serves as a unifying corridor throughout the community. The roadway system is already patterned after a traditional grid system providing access to the compass directions. It should serve local trip traffic. Using the local roads, neighborhood residents can relieve the two major corridors (Snelling Avenue and Highway 36) oflocal traffic congestion. The grid system should be retained and expanded as future development is realized. It is hoped that this dispersion of traffic will eliminate the need to continually widen major corridors. The pedestrian system in the Cornerstone follows the street system and adopted pathway system with sidewalks placed within the public right-of-way. Mass transit in the form oflocal circulator and commuter buses, as well as express bus routes between communities, will continue to provide the primary source of public transportation. Bus drop-off lanes and spaces need to be constructed along the Cornerstone corridors such as Lexington Avenue. The local bus system feeds into the hub at Rosedale, as well as head south to the center cities. In the future the local bus system may convert to or connect into the dedicated bus transit lane or light rail system. Parking within the Cornerstone area is currently provided by private improvements within each site. There is and will be very limited amounts of parking within the public street system. In order to reduce the need for on street parking, the Cornerstone plan anticipates that parking in consolidated areas and underground may occur in the multi-family structures and mixed use structures. As new developments occur in the Cornerstone area, the City may request that areas designated for on-site parking also have an air rights easement for future public and/or private structured parking above the surface space. In addition, as new developments occur with office uses, the City will request that parking spaces at grade be screened and depressed three to five feet in order to allow for doubling the size of the parking facility by simply adding a parking deck above the surface grade. with proper screening. Storm water management in the Cornerstone districts is currently planned within the City-wide comprehensive storm water management plan. As a portion of that plan, future on-site surface parking areas will be required to capture high intensity rains and allow the rain water to be released more slowly into the City's public storm sewer pipe systems. In addition, storm water detention will occur in numerous ponds along the sides of the Cornerstone. These detention ponds should be landscaped to provide an amenity as redevelopment occurs in those areas. Utilities in the Cornerstone, including drinking water and sanitary sewer, are currently designed to provide for maximum capacity of development throughout the Cornerstone areas. Installation of new utilities will occur only at the time that new road systems are installed. 7
