d. Wetlands, intermittent and perennial stream corridors, and riparian areas. e. Natural resource areas designated in the Metro Plan diagram as -adopted natural resource inventory. 2. 5 inventory: a. including but not limited to anticipated building locations, bulk and height, location and distribution of recreation space, parking, roads, access and other uses, will: (1) Avoid unnecessary disruption or removal of attractive natural features and vegetation, and (2) Avoid conversion of natural resource areas designated in the Metropolitan Area General Plan to urban uses when alternative locations on the property are suitable for development as otherwise permitted. b. Proposed buildings, road, and other uses are designed and sited to assure preservation of significant on-site vegetation, topographic features, and other unique and worthwhile natural features, and to prevent soil erosion or flood hazard. inventory, per the April 12, 1978 Scenic Sites Working Paper, which designates the subject site as Natural Sites of Visual Prominence and Prominent and Plentiful Vegetation. As such, the provisions of EC 9.8320(4)(a)(2) are applicable to the proposed tentative PUD. As previously described in the context of applicable South Hills Study policies, and in general, the applicant has attempted to minimize impacts to the site by clustering residential lots and other development impacts in areas of previous manmade impact, less steep terrain, and less dense or otherwise less significant vegetation. The proposal includes significant conservation areas on the steepest slopes of the site. Based on the available information, including the tree preservation plan and the corresponding tree preservation list represented on (sheets L3.0 through L3.4 and L4), the areas included in common open space (Tract A) and within individual lot preservation areas comprise the majority of significant trees, vegetation, and other natural features which are suitable for preservation; while also accommodating street extensions, utilities, and other infrastructure in a compact manner to serve a reasonable level of low-density residential development. the context of the above criteria. For example, the proposal of common open space (Tracts A, B, C, and D) along with the individual preservation areas of lot 5 and lots 8 through 19, results in approximately 33% of the site being preserved, primarily on the eastern side of the site, where natural vegetation is the heaviest. Also, the proposed placement of Cupola Drive along a formerly cleared and graded vehicle accessway will limit the necessary grading and associated cut and fill, which helps to minimize soil erosion and flood hazard. Locating Cupola Drive in this area also requires fewer tree removals since trees have already been removed along the vehicle accessway. The applicant has proposed to include notes on the plan set regarding tree Capital Hill PUD (PDT 17-1) February 2018 20 Page 20
