Preliminary Plat iKeview: Alpine Acres <br />May 16, 200.3 <br />Page 5 of {5 <br /> <br />Sidewalks: City Code requires' the installation of sidewalks along one side of all non cui-de-sac <br />public streets, The preliminary plat is proposing to provide a 5-foot sidewalk along Sodium <br />Street, Radium Street, and Tungsten Street, which complies with City Code. <br /> <br />Open Space: City Ordinances require that at least 40% of the development consist of open <br />space. Qualifying areas include grassed lawns, landscaped areas, gardens, natural areas, <br />landscape rock, mulch, wetlands, and ponding areas. At least 10% of the open space must be <br />shown as an easily identifiable common area for the use of the surrounding residents. The <br />preliminary plat is proposing 40% open space or 17.0 acres. The identifiable con,non area <br />requirement is 1.7 acres in size. The development is showing six (6) common open space nodes <br />throughout the development to meet the 1.7 acre cornn-~on open space requirement. It should be <br />noted that in order for the .5 acre open space area located at the southeastern corner of the <br />property to be coutnted towards the required identifiable common open space area, a connection <br />will need to be made. <br /> <br />The Park and R.ecreation Commission does not intend to develop and maintain the .5 acre park at <br />the present time. Therefore providing for an immediate access to the open space node is not <br />necessary. However at such time when the park is developed, it will be important that a <br />connection be made from the towrflxome units to the open space node. Therefore, staff ,,viii be <br />recommet~ding that tine City receive a cash deposit for the construction of the f~ture eormection. <br />The developer will be responsible for providing an estimate for the cost to construct a suitable <br />connection and such amount will be addressed in the Development Agreement. The <br />Development Agreement will be drafted upon the City receiving the final plat. <br /> <br />Stormwater Manat~ement Fee: The City has enacted a stormwater management fee of $375.00 <br />pet- unit. A payment in the amount of $75,750 will be required prior to the City releasing the plat <br />for recording. The existing homestead is exempt from the stormwater management fee. <br /> <br />Tree 'Preser,zation Plan: A tree preservation plan was submitted to the City. However, all that <br />is indicated'on the plan is areas where trees will be preserved. There is no information about the <br />number of trees to be preset'veal, the species being preserved, or their sizes. A more detailed plan <br />needs to be submitted for review and approval by the City. This will also help clarify whether <br />other planting requirements (such as density transitioning) will be met. <br /> <br />.Densit-v Trnnsitioning: City Ordinances require a transition between higher density <br />developments and lower density developments. The subject development is required to provide <br />density transitioning along the western edge of the development as it is located adjacent to four <br />existing single-family homes. The preliminary plat is proposing to satisfy density .[?ansitioning <br />tl:u'ough the landscape buffer option. Tim buffer area is required to be a twenty-five (25) foot <br />wide area located along the common boundary. <br /> <br />This common boundary is roughly 1,000 feet in length, which would require a minimum of <br />twenty (20) deciduous overstory trees, twenty (20) evergreens, and twenty (20) understory trees <br /> <br /> <br />
