7A Page 25 The acoustical engineer for the Draft EIR has provided options that Costco and the City may consider for the purpose of fulfilling this Condition of Approval if the project is approved and this condition remains relevant. The engineer explains that there are four areas at the proposed tire center where noise control can be implemented with reasonable effort in the following order of priority: 1. A wing wall 10 feet in height can be erected along the northern installation area entrance to absorb side noise leakage. The horizontal extent of the wall should be 30 feet outward from the warehouse building wall, and then taper quickly to ground level within an additional 10 feet. To reduce multiple reflections between the warehouse wall on the south side of the installation center entrance and the proposed wing wall, use of SOUND BLOCK for the wing wall facing the drive aisle is recommended. 2. The interior of the installation center should be equipped with sound absorption panels such as NOISHIELD on vertical wall surfaces, and suspended hanging baffles near the ceiling. 3. The wall at the self-storage facility could be treated with a sound absorbing surface to enhance the recommended landscaping along the wall using a material such as STARKUSTC. It is assumed the City would negotiate with the facility owners regarding the application of such material and to determine whether the exterior walls could support such a treatment. 4. The warehouse building wall along the south side of the tire center entrance may be a reflecting surface. With interior noise baffles, the amount of air wrench or other installation noise leaving the building will be reduced and the recommended wing wall will intercept most reflections. Treatment of this wall remains an option; however, the potential benefit versus the cost would be minimal. With regard to the caretaker's unit at SafKeep, staff has confirmed that a caretaker's unit does exist at this industrial facility, and is located on the second floor in the front of the building facing Middlefield Road. This property is within unincorporated San Mateo County, not the City limits. The property is zoned by the County for industrial uses. In Redwood City, caretaker's units are considered an acceptable accessory use for storage facilities, but are not given special consideration with regard to noise. They are considered part of the industrial use. In addition, the City does not have restrictions on noise levels in industrial zones, only residential areas. AL TERNA riVE ANALYSIS Item #10: The issue of evaluating the Century 12 movie theater site (located at 557 E. Bayshore Road) as an alternative site for the Costco project was raised on the Draft EIR and responded to in the Final E1R (see page 3-87 of Final EIR). The rationale for evaluating the Century 12 site as an alternative site for the Costco project is clearly described on page 9-7 of the Draft EIR. As stated in the Draft and Final EIRs, the Century 12 site was selected for evaluation for several reasons. First, the site has the appropriate zoning and General Plan designations that would allow a big-box retail development. Second, the site has the acreage and configuration (i.e., with access and visibility to freeway) appropriate for a big-box retail. Third, the site has been evaluated 7
