Any tree(s)including size and species as defined in Chapter 17.16 of this code, whether or not such tree(s) is to be removed, or destroyed, on the site plan or on a separate plat; G. Sufficient dimensions to show right-of-way widths,pavement widths,radii of curvature of center lines, street grades, whether streets are to be public or private, and all proposed frontage improvements on new and existing streets; H. A current preliminary soils and geological report prepared by a registered civil engineer and a registered geologist; I. A detailed landscaping plan showing the natural open space which will remain upon completion of development, all existing trees (and indicating which trees are scheduled for removal), and the precise boundaries of additional landscaping; the landscape plan shall include container size of all trees and shrubs, species of all plant material, irrigation system plan, street lighting, low level path lighting, street furniture and fencing materials, dimensions and locations; J. A statement in writing stipulating to the total number of bedrooms to be constructed; and K. The initial plan shall indicate the density allowed by subsection A of Section 18.76.150 and the location of the proposed units. Any request for density adjustments allowed by subsection B of Section 18.76.150 shall be shown on an alternate plan detailing the location of the additional units and amenities. Notwithstanding the requirements of this subsection,an applicant for an H-P-D permit for the development of five or more acres, which development will occur in stages, may submit general information relating to subsections A and I of this section for review by the planning commission. Precise and detailed plans setting forth the information required by these items shall be submitted to the planning commission for its review and approval prior to the approval of a tentative subdivision map, building permit or other construction authorized by the H-P-D permit. (Prior code § 2-2.3209(f) 18.76.150 Density. A. Base Density. A base density for a piece of property shall be determined by the following: Percent slope 10% 15% 20% 25% Greater than 25% *WIS 9.9 14.9 19.6 24.2 Greater than 24.2 Base Density 3.5 2.8 1.8 1 0.2 *Corrected number values. Any WIS not shown in the table shall be determined by interpolation, using the graph set forth in Exhibit A of the ordinance codified in this chapter, and incorporated in this chapter by reference. B. Density Adjustments. The effectiveness of hillside development can be affected by a number of factors such as the physical characteristics of a specific parcel,the amount of landscaped and natural open space existing within a development, the existence of amenities within a development and the number of people who will reside in the hill area. Therefore, in order to encourage hillside developments which take into consideration the factors provided in this subsection, adjustments may be made in the base density in the recommendation for approval and approval of an H-P-D permit, pursuant to any of the following: 1. The existence of open space beyond that required by Section 18.76.160; 2. The existence of amenities or on-site or off-site improvements which are not normally found or required in residential developments; 3. The existence of a mixture of housing types which provides a variation in the appearance of the development and allows a range of housing prices; http://gcode.us/codes/pleasanton/view.php?topic=18-18_76&showAll=1&frames=on 11/13/2012
