Site Plan Review: Alpine Acres 2nd Addition May 30, 2003, Revised June 20, 2003 Page 3 of 4 Maximum Driveway Width: The maximum driveway width permitted for each unit is 20-feet. The site plan appears to meet this requirement, however the site plan should be revised to include this information. Architectural Standards: Building elevations need to 'be provided for the structures. Staff understands that the exterior building materials will consist of vinyl siding and 'brick accents. Landscaping: According to the plan dated April 30, 2003, there will be two 3-unit buildings resulting in a total of six (6) units. For each unit, there should be a minimum of two overstory trees, four ornamental trees, and twelve shrubs (resulting in a minimum of 12 overstory trees, 24 ornamental trees, and 72 shrubs). The plans indicate that seventy-three (73) shrubs will be installed, which exceeds (by one) the minimum shrub requirements. However, it appears that only eleven (11) overstory trees and twelve (12) ornamental trees are being planted. To meet the minimum requirements, at least one additional overstory tree and twelve (12) additional ornamental trees need to be installed. The City needs to receive and approve a revised landscaping pi.an that shows these plantings as well as the species and size. All the species included in the species palette are acceptable as outlined in the R .amsey Tree Book. Furthermore, all sizes indicated on the plan meet the minimum requirements. One concern regarding the species palette is the number of Norway Maples and Radiant Crabapples being planted. The City would prefer to' see a geater amount of species diversity to protect against possible pest/pathogen infestations. Again, a revised landscaping plan showing a greater mix of species should be submitted and approved prior to final plat approval. Staff will need to receive a revised landscape plan to reflect the decrease in building units from 6 to 4. Screening: The R-2 district stipulates that a thirty (30) foot wide bufferyard be included anywhere that a proposed higher density zoning district abuts a lower density zoning district. Within the bufferyard, an additional 10% percent of landscaping is required based on the minimum landscape plantings. It should be noted that the R-2 district screening and density transitioning requirements, addressed as part of the preliminary plat, conflict with one another. City Staff and the Environmental Policy Task Force (EPTF) are currently reviewing the screening requ/rements established in City Code to provide for a more effective and efficient means of requiring additional plantings within the buffer corridor. Therefore staff is using the density transitioning requirements to satisfy screening due to density transitioning requiring more plantings in this case. -246-
