70) construction of noise attenuation barriers as shown in Figure 6-1 of the Specific Plan shall use building construction techniques to reduce noise to the extent feasible, where outdoor use is a major consideration (eg. backyards in single- family residential areas and recreational areas in multi-family residential areas), consistent with other Specific Plan goals. b) Residences that abut the open space and that are affected by a roadway sound source may be subject to ambient noise levels following construction of noise attenuation barriers without further exterior noise mitigation as described above being required. c) For residential uses in areas where the noise source fi.om a railroad (e.g. along the UPRR tracks) exceeds a maximum train pass-by level of 75 dBA, interior noise shall be limited to a maximum instantaneous noise level of 50 dBA in bedrooms and 55 dBA in other rooms through a combination of soundwall and building construction techniques. Noise-Sensitive Park Uses. For park uses where the ambient noise levels exceed 65 dBA Leq (daytime noise), locate noise-sensitive park uses in areas where the ambient noise level is projected to be less than 65 dBA. N. WETLANDS AND BIOLOGICAL RESOURCES 71) Wetlands Assessment. If needed, Property Owner shall prepare a pm-jurisdictional wetlands assessment satisfactory for U.S. Army Corps of Engineer's permit review prior to any development activity (including grading) on the Project site. Property Owner shall obtain verification from the Army Corps of Engineers (Corps) of the Corps' jurisdiction of wetlands and other federally regulated waters of the U.S. on the Project site prior to application to City for any grading permit. 72) Permit Required. If needed, Property Owner shall obtain necessary approval of a Clean Water Act Section 404 permit fi.om the Corps and/or any other governmental agency with Section 404 authority prior to application for a grading permit fi.om City to fill jurisdictional wetlands and 9ther federally regulated waters of the U.S. A letter from the Corps, or copy of the permit, shall be submitted to the Planning Director indicating that necessary permits for altering or filling wetlands or other federally regulated waters have been obtained, or that such permits are not required. Any additional conditions related to grading imposed by the Section 404 permit shall become conditions of applicable grading permits. 73) Wetlands Mitigation Plan. Property Owner shall retain a qualified wetland consultant to prepare a detailed Wetlands Mitigation and Monitoring Plan, including identification of avoidance alternatives, if Corps requires mitigation for those areas to be filled. Such Mitigation Plan shall be submitted for review and approval by the Corps and the Planning Director, and shall be consistent with the Corps' Habitat Mitigation and Monitoring Conditions of Approval Page 39 of 44 August 9, 2000
