Legacy Christian Academy Final Plat and Site Plan Review December 8, 2010 Page 3 of 7 canderson(dci. ramsev. mn. us 763 - 433 - 9905 Landscape Plan: Based on the lineal footage of the site (11,550 feet), the number of proposed parking stalls (692) and the additional required plantings for the bufferyard area, a total of 358 trees and 385 shrubs are required. The proposed landscaping plan includes 320 newly planted trees (as well as about thirty -four [34] existing trees that will be preserved) and includes a list of various shrub species that will also be planted (but without identifying quantities). The following comments are offered regarding the revised Landscaping Plan, dated November 1, 2010, prepared by Anderson Engineering: • The landscape plan must indicate quantities of each species and exact location of each species throughout site (by way of unique symbols or labels). • Minimum required size at time of planting is twenty -four (24) inches in height/width for shrubs, whichever dimension is more applicable per species. Minimum size must be included on the plan. • At each of the four (4) entrances to the site, the vision clearance triangle must remain free of any plantings to ensure unobstructed site lines. The vision clearance triangle can be determined by connecting two (2) twenty -five (25) foot `legs', which run parallel with the curb, with a third leg. This area shall remain free of any plantings and should be indentified on the landscaping plan. • The landscaping plan must differentiate those areas that are to have sod and those areas proposed to be seeded. City Code requires all disturbed areas to be sodded. Any deviation from this condition requires City Council approval. • All landscaped areas must include in- ground irrigation. The irrigation system must include rain sensors and back -flow prevention devices, which must be noted on the plan. • All irrigated and landscaped areas must be covered with six (6) inches of topsoil that meets MnDOT's Premium Topsoil Borrow specification. If amending onsite topsoil, documentation must be supplied to the City to verify that the amended material has been tested and meets MnDOT's Premium Topsoil Borrow specification. The topsoil requirement and specification must be noted on the plan. • A forty (40) foot bufferyard between the school and the adjacent single family lot on Puma St must be maintained and should include at least fifty -eight (58) trees (which is equivalent to an additional 25% of the required site plantings [231 trees excluding the parking lot plantings]). The buffer width on the plan is acceptable but additional plantings are required (while some landscaping exists on the single family lot off Puma St, it is the responsibility of the Applicant to provide all required plantings and area to satisfy the buffer yard requirement). o Additional plantings should consist of coniferous species to provide more year round buffering. o Spacing between plantings should be reduced. It appears that the trees are about thirty -five feet on center. This distance can be reduced by almost fifty percent (50 %) to provide more thorough screening/buffering. o Incorporating multiple rows of trees, at staggered positions, is also encouraged to provide more thorough screening/buffering.
