and grading, building foundations, flatwork, retaining walls, and pavements. The project's proximity to the Zone 7 lake was also analyzed for potential geologic hazards. From a geotechnical engineering standpoint, Cornerstone Earth Group states that the proposed development can be constructed as planned, provided that the recommendations contained in the report are incorporated into the project design and grading. Examples of recommendations include: remove the existing soil stockpiles and only reuse them for backfili if they meet certain criteria; compact soils in accordance with the latest American Society for Testing and Materials standards; and post-tensioned concrete mat foundations need to be based on procedures developed by the Post-Tensioning Institute (latest edition) and as referenced in the 2007 California Building Code. Cornerstone Earth Group also determined that the proposed development was set back an adequate distance from the top of the Zone 7 lake's slope bank to avoid any potential geologic hazards. A condition of approval has been included that requires the applicant to comply with the recommendations listed in the geotechnical report. The geotechnical study was reviewed and conditionally accepted by the City Engineer. The City Engineer has requested that a condition of approval be included which requires the unstable portions of the adjacent Zone 7 lake's slope bank be repaired prior to the construction of Lots 31 through 42 unless pier and grade beam foundations are used for these homes. Architecture and Desien The project proposes four different plans: Residence One, Two, and Three are single-story homes with three elevation styles each; and Residence Four is two-story home with three elevation styles. The elevation styles include "Mediterranean," "Cottage," "Tuscan," and "Napa Craftsman." Nine different color schemes generally comprised of earth tones and natural colors are proposed for exterior paint, stone, brick, and roof colors. In order to ensure that the colors compliment the architectural style of the proposed homes, some of the color schemes are limited to a specific elevation style. Staff generally feels that the building designs are attractive and that the architectural styles, finish colors, and materials will complement the surrounding development. Staff is recommending a few minor changes which it believes would enhance the overall design of the project: 1) staff believes the building architecture should be "four-sided," with front elevation trim/window elements carried through on all sides of the buildings; 2) staff recommends that additional cornice detailing be added to the turret on the "Mediterranean" elevation and that the turret roof pitch be slightly steepened, if feasible, on this elevation type; and 3) since the "Tuscan" and "Mediterranean" elevations on Residences Three and Four have basically the same first floor elevations, staff is recommending that the same elevation types not be placed next to each other. Conditions of approval address these recommendations. In addition, since actual samples of the roof, stone, and brick have not been provided, staff has included a condition which requires that actual color/material samples of the roof, stone, and brick be submitted for final review and approval by the Director of Planning and Community PUD-74 Page -14 - June 25, 2008
