Type Mitigated Negative Declarations
SCH# 2008062049
County Name Contra Costa ( North / Coastal CA Region )
Lead Agency Contra Costa Water District
Abstract
The Downtown Concord Water Main Replacement Project consists of replacement or abandonment of approximately 6,425 feet of existing water mains that are located in: Galindo Street between Salvio Street and Concord Boulevard; Willow Pass Road between Galindo Street and Third Street; Grant Street between Pacheco Street and Clayton Road; and Concord Boulevard between Galindo Street and Port Chicago Highway. CCWD records show that the water mains are shallow with approximately 3-feet of cover. CCWD records also indicate that there are 7 fire hydrants, 42 water meters, 19 in-line valves, and 7 tapping valves along the pipelines to be replaced. Construction of the pipeline replacements would require trenching between 4 to 6 feet in depth by 30 to 36 inches in width for the length of pipeline being replaced.
