Preliminary Plat Review: Alpine Acres May 16, 2003, revised June 6, 2003 Page 5 of 6 trails outside of the plat boundary, however the developer receives a credit against trail fees for the construction of the trail. Sidewalks: City Code requires the installation of sidewalks along one side of all non cul-de-sac public streets. The preliminary plat is proposing to provide a 5-foot sidewalk along Sodium Street, Radium Street, and Tungsten Street, which complies with City Code. Open Space: City Ordinances require that at least 40% of the development consist of open space. Qualifying areas include grassed lawns, landscaped areas, gardens, natural areas, landscape rock, mulch, wetlands, and ponding areas. At least 10% of the open space must be shown as an easily identifiable common area for the use of the surrounding residents. The preliminary 'plat is proposing 40% open space or 17.0 acres. The identifiable common area requirement is 1.7 acres in size. The development is showing six (6) common open space nodes throughout the development to meet the 1.7 acre common open space requirement. It should be noted that in order for the .5 acre open space area located at the southeastern corner of the property to be counted towards the required identifiable common open space area, a connection will need to be made. The Park and Recreation Commission does not intend to develop and maintain the .5 acre park at the present time. Therefore providing for an immediate access to the'open space node is not necessary. However at such time when the park is developed, it will be important that a connection be made from the townhome units to the open space node. Therefore, staff will be recommending that the City receive a cash deposit for the construction of the future connection. The developer will be responsible:for providing an estimate for-the cost to construct a suitable connection and such amount will be addressed in the Development Agreement. The Development Agreement will be drafted upon the City receiving the final plat. Storrnwater Management Fee: The City has enacted a stormwater management fee of $375.00 per unit. A payment in the amount of $75,750 will be required prior to the City releasing the plat for recording. The existing homestead is exempt from the stormwater management fee. Tree Preservation Plan: A tree preservation plan was submitted to the City dated April 25, 2003. There are seven different "tree save" areas that show a total of 143 existing trees that are to remain after the development occurs. At the northern end of the development, a large stand of cedars (totaling 54 trees) is being preserved. The majority of the remaining trees to remain are oaks ranging from seven (7) to twenty-four (24) inches in diarneter. There is als0 a-large white pine that is being preserved just north of the existing single-family homes. Most of the "tree save" areas appear to be designated green space which is ideal. Density Transitioning: City Ordinances require a transition between higher density developments and lower density developments. The subject development is required to provide density transitioning along the western edge of the development as it is located adjacent to four existing single-family homes. The preliminary plat is proposing to satisfy density transition'ing
