The 100-year flood zone includes only the front portion of this property. The proposed use is not prohibited in the flood frince; however. new construction is subject to the Standards for Flood Hazard Reduction in the Planning Title (Section 9-10325). Noise: In 1986, to update the Noise Element of the General Plan, BBN Laboratories, Inc., prepared tables of current and projected noise contours for specific roads, railroads, and airports in the County. The building is located within the 65 db CNEL noise contours of Interstate Route 205, projected for the year 2005. Section 9,800(e) of the Planning Title states the following: "New homes for the care of the aged and infirm, rest homes, educational institutions, and hospitals shall conform to the following: '(1) The maximum exterior noise level entering new homes for the care of the aged and infirm and resthomes is 60 db Ldn at three feet from any of the building's exterior walls; "!`n 1V0 new homes for the care of the aced and infirm and resthornes may be built in areas located within the present or future 65 db Ldn noise contour as designated by the San Joaquin County Noise Element without noise reduction such as, but not limited to, siting or noise barriers;" The Development Services Division recommends as a Condition of Approval that a noise study be prepared and that mitigation measures cited in the study be implemented. ENVIRONMENTAL CONSIDERATIONS: An Initial Study was prepared for this.project on October 1, 1991, and no significant environmental impacts were identified. On the bases of that review, a Negative Declaration was prepared. In addition, a "De Minimis Impact Finding' has been prepared which states that the project will not have an adverse impact on wildlife resources.
