Since the nature of the combined Phase II Specific Plan and Park Master Plan is substantially one of preserving open space and re-establishing wildlife habit, the resulting negative environmental impacts are projected to be relatively limited. The primary areas of environmental concern expressed by the community regarding the Bernal Property to date and analyzed in the Draft EIR include aesthetics, visual resources, noise and traffic. A summary of impacts and mitigations for each of these areas of impact is presented below. Aesthetics Impact The Phase II Specific Plan and the Park Master Plan incorporate "built-in" mitigation measures relating to sports field lighting that includes "cut-off' shields and luminaries that direct illumination onsite and downward, separating sensitive receptors (e.g., the residential area to the west) from the light sources by intervening land area (Grand Meadow), and landscaping the intervening area with mixed deciduous and evergreen tree species to ensure year-round screening. Visual Impact Both the Specific Plan and Park Master Plan call for siting community facilities and trees along Bernal Avenue and 1-680 in ways that will achieve a pleasing open view into the site and to retain key vistas eastward across the site to the Southeast Hills and westward across the site to Pleasanton Ridge. Specifically: · Bernal Avenue and 1-680 landscaping are to preserve views by creating gaps that frame distant views. · Building and tree height and location within 800 feet of Bernal Avenue east of the Fire Station are to be carefully managed to minimize the visual screening of views toward the Southeast Hills and Pleasanton Ridge. · Landscaping on top of berms is to be arranged to retain views of Pleasant on Ridge from 1-680. Noise Impact The following site plan and noise attenuation measures are included in the Specific Plan for use when planning noise sensitive uses in the vicinity of noise sources. · Noise levels at child care facilities and at the potential Cultural Arts Center should not exceed 60dBA Ldn in outdoor noise sensitive areas, and interior noise levels should not exceed 45dBA Ldn. A qualified acoustical consultant is to become involved in the design of noise sensitive use mitigations to ensure compliance with the General Plan and Specific Plan. SR06:l42 Page 8
