Title
Recommendation to Authorize the City Manager to Execute an Agreement with Tetra Tech, Inc. for Post Construction Project Closeout and Second Amendments to Agreements with BKF Engineers and Park Engineering, for the Cross Alameda Trail (Main Street to Constitution Way) Project, in a Cumulative Amount Not to Exceed $145,633.

The extra work, not anticipated in the original plans, includes improving the existing storm drain and sanitary sewer manholes to mitigate their aged condition and to meet the new final finish grades.

Sufficient funding is available in the project budget to approve the contract amendments and the new contract.
