surfaces tributary to the street. Since nuisance flows usually originates in the street, they commonly contain many common pollutants found in streets such as oil/grease, metals and sediment. Because the proposed project involves an auto servicing/auto repair use there is a higher potential for water quality impacts associated with substances such as oil and grease. To minimize the potential for degraded surface water impacts generated from the proposed project, the all entrances of all service bays perimeter of the garage area shall have a raised curb to retain surface water runoff on the project site. Additionally, during construction operations Best Management Practices would be employed to minimize potential construction-related water quality impacts. Mitigation Measure · Building plans for the proposed proj ect shall reflect a raised curb around the perimeter of the garage area to retain surface water runoff onsite. . The service area shall be constructed to drain underground clarifier/sump/tank equipped with a off valve that can stop further drainage of water or spilled material into the street and drain system. to an shut- storm storm · Construction plans for the proposed project shall reflect that Best Management Practices would be employed for all exterior construction activities. B. Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level. Q. Have a potentially significant adverse impact on groundwater quality? No Impact Construction operations for the proposed project would not require de-watering activities. The long-term operation of the proposed project would not have any impact on groundwater supplies. Additionally, the proposed project would not interfere with ground water recharge because the 13 75A~2'9
