FOR THE CONSTRUCTION OF THE LAFAYETTE /PLEASANT HILL ROAD TRUNK SEWER, DISTRICT PROJECT NO. 5994 rehabilitated. The project will install approximately 5,600 linear feet of 6- to 18 -inch sewer pipe. District staff prepared the plans and specifications for the project. The Engineer's estimate for construction of the Lafayette /Pleasant Hill Road Trunk Sewer is $2,300,000. This project was advertised on March 22 and 29, 2011. Eleven (11) sealed bids, ranging from $1,729,650 to $2,521,480, were received and publicly opened on April 12, 2011. The Engineering Department conducted a technical and commercial review of the bids and determined that Mountain Cascade, Inc. is the lowest responsive bidder with a bid amount of $1,729,650. Despite cost increases in fuel and oil products in the past few months, staff continues to receive favorable bids. A summary of bids received is shown in Attachment 2. The District will administer the construction contract and will provide contract administration, inspection, survey, office engineering, and submittal review. The funds required to complete this project, as shown in Attachment 3, are $2,269,000. The total cost of the Lafayette /Pleasant Hill Road Trunk Sewer is anticipated to be $2,614,000. This project is included in the fiscal year (FY) 2010 -11 Capital Improvement Budget (CIB) on page CS -55. Staff has conducted a cash -flow analysis of the Collection System Program budget and concluded that adequate funds are available for this project. Staff has concluded that this project is exempt from CEQA under District CEQA Guidelines Section 15302, because it involves replacement of existing sewer facilities at substantially the same locations and with the same purpose and level of activity as the facilities being replaced. Any capacity increases are for non - growth inducing, wet - weather purposes. This project also is exempt under District CEQA Guidelines Section 15061(b)(3), since it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment. This certainty is based on the District's past experience with numerous sewer construction projects of this nature, the relatively short distances involved, and the District's mitigating construction specifications. These specifications are standardized general and special conditions that are made part of the project bid documents to address environmental considerations, such as protecting trees and riparian areas, as well as compliance with applicable federal, state, county, district, municipal and local laws, ordinances, orders, and regulations.
