Planned Unit Development and Preliminary Plat. Plans have been submitted illustrating the lot layout for the proposed development. For the first phase south of Allan Avenue, 74 twinhome units are proposed, resulting in a gross development density of 5.5 units per acre including the street, or a net density of 7.2 units per acre excluding the street area. For the second phase north of Allan, 22 units would be added on developable land of about five acres. The overall net density would be about 5.8 units per acre, plus about 3 acres of wetland and 2.2 acres of Allan Avenue right of way. The plans illustrate a 60 foot wide Allan Avenue, with 50 foot "rights of way" shown for the cul -de -sac streets to the south. The developer has indicated a proposal for the cul -de- sacs to be privately maintained. As a result, the setbacks from the cul -de -sac streets (fifty feet) would be acceptable under the PUD. Perimeter and Allan Avenue setbacks are all in compliance with City regulation. For final PUD approval, the City will need to see a site plan which illustrates all site improvements, including: • Preliminary floor plans, illustrating the layout of the building on the proposed lots • Driveway locations, illustrating adequate snow storage on the cul -de -sacs • Common mailbox sites, avoiding interference with driveways and snow storage areas Height of proposed buildings, illustrating compliance with building separation requirements Landscape plans illustrating both typical foundation planting and all common space planting, including the screening and buffering to the north industrial boundary Utility and Grading and Drainage Plans must be reviewed by the City Engineer and Public Works staff. In addition, any wetland alterations must be reviewed by the Ramsey - Washington Metro Watershed District for compliance with the district's wetland mitigation policies. CONCLUSION The Petrina Park Terrace PUD is potentially compatible with area land use and public services, with the possible exceptionpf the industrial boundary to the north and northwest. We would recommend significant buffering of this boundary to maintain the ability of the industrial park to function in a reasonable manner, and to assure the development of an attractive, quiet residential neighborhood. These plans should be submitted as a component of the Final PUD /Final Plat development review. Density in the development is calculated at approximately 5.5 dwelling units per net developable acre, exclusive of wetlands and public streets, well within the range specified by the R -2 Zoning District. Traffic in the development should be less than that expected if the area were to develop industrially, both overall and in the peak hour. Upon verification from the City Engineer 3 Page 7
