Pimlico Drive Turnout and Pipeline Project Environmental Checklist vault sites, R to 10 at the fluoridation building and 6 to 8 daily at the Santa Rita control valve vault. Equipment delivered to the construction site will include twenty-toot long sections of 20-inch ductile iron pipe, pipe backfill and bedding materials, pre-cast concrete vaults, concrete masonry materials, and mechanical equipment. These materials and equipment will be delivered to the constntction site by 40-foot (or smaller) flatbed trucks and 10-wheel dump trucks. Assuming pipeline installation advances at about 100 feet per day, approximately 2 to 4 track trips per day will be required to remove excavated material and deliver backfill material, equipment and materials, asphalt and concrete or 130 to 160 truck trips over the pipeline construction period. A total of approximately 1 to 2 truck trips will be required to deliver materials and equipment to the Pleasanton vault and Zone 7 turnout site daily or about 10 to 20 trips over the construction period. Equipment and materials delivery to the fluoridation building will be about 10 to 15 truck trips a day or total 15 truck trips over the construction period and 4 to 5 truck trips to the Santa Rita control valve vault site over a two week period. Two staging areas will be used for materials and equipment. One staging area will be located adjacent to the fluoridation building site and the other will be located in the parking lot adjacent to the Santa Rita control valve vault. Alternate staging areas would be approved by the City of Pleasanton prior to start of construction. Once construction is completed, the roadways, sidewalks, and curves and gutters will be resurfaced and returned to preconstntction conditions. The area around the fluoridation building will be landscaped with ornamental shrubs and vines will be planted along the side of the building facing Pimlico Drive. The area surrounding the Santa Rita control valve vault site disturbed by construction will be landscaped with grass to bleed in with the surrounding lawn area. Measures Included in the Proiect The following is a list and description of measures and standards that have been incorporated into the Project Description in order to avoid or minimize potential environmental impacts. These measures represent standard engineering, design, constntction, and maintenance practices. Project Measure AIR-1: Equipment Exhaust Control The City shall control equipment emissions when working within 100 feet of sensitive receptors such as businesses or residences, or when more than three pieces of heavy construction equipment are operating simultaneously. These measures shall include: • The Construction Contractor shall properly maintain construction equipment per manufacturers specifications; • The constntction Contractor shall reduce unnecessary idling of construction equipment (i.e. limit idling time to 10 minutes or less) and avoid staging equipment within 200 feet of sensitive receptors; and City of Pleasanton 10 Winzler & Kelly Draft Initial Study/Proposed Negative Declaration August 200(, 04263501
