BENDER READY -MIX CONCRETE MANUFACTURING PROJECT Initial Study /Mitigated Negative Declaration 2.0 PROJECT DESCRIPTION 2.1 PROJECT LOCATION Regionally, the project site is located in the City of Santa Ana (City), within the County of Orange; refer to Exhibit 2 -1, Regional Vicinity. Locally, the project site is located at 516 South Santa Fe Street, within the eastern portion of the City. The site is approximately % -mile west of Grand Avenue, Y< -mile south of First Street, and' /, -mile southwest of Interstate 5 (1 -5). 2.2 ENVIRONMENTAL SETTING 2.2.1 EXISTING LAND USES The 0.97 -acre project site is currently occupied by the Bender Ready -Mix concrete manufacturing facility. The facility produces and sells large quantities of concrete through the processing of aggregate and other raw materials. The concrete is prepared, loaded into truck- mounted rotating drum mixers, and hauled away for use at construction sites. Generally, concrete is sold to independent truck contractors; however, Bender Ready -Mix also delivers concrete directly to customers through its own fleet of trucks. The facility is composed of the following primary components: • Maintenance /Office Structure: A 7,001 square -foot single -story structure exists on the northern portion of the site. The structure is utilized for material /equipment storage, vehicle maintenance, and office space. The building is equipped with several large roll -up doors allowing for the entrance of heavy trucks. The western portion of the structure (fronting South Santa Fe Street) is utilized for office purposes while the eastern portion is utilized for storage and maintenance activities. • Aggregate Storage Area: The southeastern portion of the site is utilized for the storage of raw materials necessary for concrete manufacturing. These materials consist primarily of sand and gravel products, and are stored outdoors in piles separated by block walls. These aggregates are delivered to the site by truck and transported from area to area within the site by bulldozer. • Concrete Batch Processing Equipment: The concrete batch processing machinery is located along the southern side of the maintenance /office structure. Raw materials are inserted, mixed, and processed within this equipment and prepared for loading. This equipment is electrically- powered. • Truck Staging Area: The truck staging area is located along the western side of the maintenance /office structure. This area consists of a ramp that allows concrete trucks to back down into an area abutting the concrete batch processing equipment. Concrete is then loaded from the batch processing equipment to trucks. • Debris Storage Basin: An earthen basin constructed within the southeastern comer of the site is utilized for storage of by- products of the concrete manufacturing process. These by- products include wash water and excess /older concrete cleared from trucks prior to loading new concrete. This basin is periodically cleared when it reaches capacity. Wash water is recycled and reused in the concrete manufacturing process. Solids are hauled off -site to a Ilandfill every one to two days, depending on demand and operations JULY 2011 2.1 PROJECT DESCRIPTION 31A-23
