B. ENVIRONMENTAL REVIEW CHECKLIST A brief explanation or reference of all answers follows each issue. I. AESTHETICS - Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? DISCUSSION: Potentially Significant Impact D o D D Potentially Significant unless Mitigation Incorporated o D D o Less tban Significant Impact. o o D ~ No Impact ~ ~ ~ o The project site is located within the city of San Leandro immediately south of the Oakland International Airport and on Port of Oakland property. The proposed trail and bridge would connect an existing pedestrian and bicycle trail that ends on airport property with the Oyster Bay Regional Shoreline park, located south ofthe Oyster Bay Slough. The area is highly visible from the park and San Francisco Bay. The trail and bridge would become a portion of the Bay Trail, a regional trail that circles San Francisco Bay. The trail and bridge have been designed to be visually compatible with open space and public recreation use. The height and design of the prefabricated steel truss bridge would not obscure or affect any scenic vistas or affect any scenic resources. The bridge itself would be constructed across Oyster Bay Slough with approximately 33 feet (1 meter) of freeboard above the high tide level. The vertical height of the bridge would be approximately 6 feet (1.8 meters) from the base to the top of the handrails. The steel truss bridge would require painting to protect it from the marine environment. The project site is within the "referral area" of the Alameda County Airport Land Use Commission (ALUC), but would not require review by the ALUC because the project is not an amendment to a plan or zoning ordinance. Staff for the ALUC, however, has indicated that the project is consistent with the ALUC plan, although any lighting included in the project must be consistent with airport plan standards (Horvath, 2004). The Alameda County Airport Land Use Policy Plan (ALUC, 1986) prohibits "any use which would direct a steady or flashing light of red, white, green, or amber colors associated with airport operations at an aircraft...." Any lighting proposed as part of the project would be of the conventional outdoor lighting standard type that directs the light downward to the trail and bridge. Thus, any light would not be directed upwards toward approaching or departing aircraft and would be in conformance with the ALUC plan requirements. Y4204IS.00693.doc - 4/5/07 -8-
