of warm exterior colors and materials, and the use of flat slate tile work together to create a rich home design that is both attractive and consistent with the requirements of the Specific Plan. Grading Plan Minor grading would be required to provide adequate drainage for the home site, because the proposed house is only expanding the existing building footprint. The proposed finished grade is at a similar elevation as Vineyard Avenue. A berm will be con- structed along the lot frontage to provide noise attenuation as required by the Specific Plan and as required along the frontage of the neighboring development (PUD-40). The berm is designed with a maximum height of six feet, and it would be contiguous with the approved berm of PUD- 40. The berm location does not impact the usable yard area for the future homeowner. No other grading is indicated on the site or landscape plans. A grading and drainage plan is re- quired as a condition of approval to satisfy both the Specific Plan requirements and to insure proper drainage is being created. Soils Investigation Report The Specific Plan requires site-specific geotechnical studies be completed for new development in the Plan Area in order to evaluate any necessary geotechnical mitigation measures. Staff is requiring a geotechnical report be provided prior to building permit issuance. The soils report will provide the necessary mitigation measures and construction procedures recommended to be carried out through construction. The mitigation measures and construction procedures will need to be incorporated into the project's design. The City Engineer will need to review the re- port and find it to be adequate and satisfactory. Noise, Dust, and Vibration The Specific Plan notes the subject lot (Lot 8) as having a noise level that exceeds a 55dBA. The Specific Plan therefore requires noise, dust, and vibration mitigation measures for new con- struction, such as: the installation of a fresh-air ventilation and/or air-conditioning system that allows residents to maintain closed windows for noise and dust control, all windows facing the RMC Lonestar plant need to be dual-paned, out-door recreation areas should be located appro- priately, record a deed restriction pertaining to the noise, dust, and vibration implications on the property, record a deed providing a noise/dust/vibration easement, and record a deed disclosing the close proximity of the Plan Area to the Livermore Municipal Airport and of possible impacts due to aircraft over flights. Staff is recommending conditions of approval that would meet these requirements. Item 6. b., PUD-43 Page 5 of 25 April 7, 2005
