I I i I I I I I I I I I I I I I I ! Preliminary Plat Review: Alpine Acres 2~'° Addition May 30, 200.3 P',:ge 3 of 4 ttmdscape rock, mulch, wedands, and pond[ng areas. At least 10% of the open space must be sh~ .'.n as an easily identifiable common area for the use of the surrounding residents. The devdopment [s proposing l acre of open space, M-rich equates to 74% open space. This plat is the second phase to Alpine Acres, which contains several nodes of identifiable common open space ar~as. S to rmw a ter Man a gement Fee: Tlxe City has enacted a storrnwater management f,:e of $375 per unit. A payment in the amount of $2,250 will be required prior to the City releasing t!~e for reco~'ding. Trce Pr:,'scrvation Plan: A tree preset'ration plan was not submitted to the City. [4owever, there do~-; appear to be some existing trees shown on the landscaping plan. It is'unclear, whether any of tlmse exi3dng trees are going to be preserved. This needs to be clarified and the preliminary plat revised accordingly. Densi~,, Transitioning: City Ordinances require a transition between higher density developments and lower density developrnents. The subject development is required to provide ~ density transitioning along tlne western and northwestern edge of the development as it is located tt,,:liacer' to existing singIe-family homes. The preliminary plat is proposing to satisfy density t~ ~sitioning through the landscape buffer option. The buffer area'is required to be a twenty-five (? ') I"oot wide area Iocal'ed along the common boundary. The ~'t~',~'thern boundary o~' the deve.(opment abutting existing single-farnily homes is roughl~ 180 feet. ': i~is results iii the need for i:bur (4) conifers, four (4) deciduous overstory trees, and three (3) ornamentals. The landscaping plan dated April 30, 2003 does not specify which plantings are being used to f~ttfill the density transitioning requirements. However, within the twenty-five foot bur?er area, there are four (4) deciduo,m overstory trees, three (3).ornamentals, and one conifer. Therefore, to fulfill the dehsity transitionir'~5 requirement roi' the northern boundary, an additional three (3) conifers need to be installed. Fhe western boundary ol~ the development abutting an existing single family house is roughly 200 'feet. To fulfill the density transitioning requirements for this common boundary, there needs to be four (4) conifers, four (4) deciduous overstory trees, and four (4) ornamentals. Again, the current plan does not specif'y which trees are being used to fn. tlfill these requiremertts. Hoxvever, within the twenty-five foot buffer area, the plan does show five (5) conifers, four (4) deciduous. overstory trees and no ornamentals. Thus, a minimum of four (4) ornamental trees need to be installed to satisfy density transitioning requirements. The City needs to receive and approv.e a revised plan specifically showhng the density transitio~ing plantings that, at a minimum, includes species and size of trees to be planted. As noted above in the [anclscaping section, a greater mix of species should be utilized to help protect against loest/pathogen infestations that can devastate monoculture plantings. -291-
