BACKGROUND
The City of Chino encompasses approximately 30 square miles, with a water service area of 29 square miles consisting of 343 miles of water distribution pipelines with 23,052 service connections. The City water service area serves a population of about 86,435 and primarily follows the City boundary. Staff developed a Capital Improvement Program that identifies, and phases recommended waterline replacement projects to ensure the City efficiently delivers safe and reliable drinking water to its customers. The selection and phasing of the projects considers the age of the pipe, material, and the number of recent historical leaks. Waterline replacement projects have been included in the FY 2024-25 budget, including the Philadelphia Street and Walnut Avenue Waterline Replacement Project (WA242). City staff has elected to separate the two waterline designs to expedite delivery and facilitate an earlier start to construction. This approach will streamline the project timeline and enhance overall efficiency.
Philadelphia Street water line replacement includes the replacement of a 12-inch steel and asbestos cement waterline upsizing to a 16-inch polyvinyl chloride (PVC) waterline on Philadelphia Street from Central Avenue to Oaks Avenue. (This is approximately ¾ mile of pipe replacement) (Exhibit A). The design includes tie-ins from the new Philadelphia Street waterline to Central Avenue, Town Square, Benson Avenue, Oaks Avenue, and seven (7) major connections from shopping centers within the project limits.
Walnut Avenue water line replacement includes the replacement of a 10-inch steel waterline (from Ramona Avenue to Monte Vista Avenue) a 12-inch steel waterline (from Monte Vista Avenue to Central Avenue) and a 12-inch transite/asbestos cement waterline (from Central Avenue to Tenth Street) to a 12-inch C-900 PVC waterline along Walnut Avenue (Exhibit B). (This is approximately 1.1 miles of pipe replacement) The design shall include tie-ins from the new Walnut Avenue waterline at all street intersections within the project limits.
Water operations will be improved by adding sufficient valving for proper shutdowns along both waterline replacements. There are multiple water service connections, hydrant laterals, and fire service laterals including valve assemblies that will also be replaced and pavement restoration.
ISSUES/ANALYSIS
On August 15, 2024, staff solicited an informal Request for Proposals (RFP) from the on-call consultant list (RFP# 2023-3003) to three (3) firms for Design Services for each waterline replacement. On August 29, 2024, the City received two (2) proposals for each location which were evaluated and ranked by the following criteria:
• Experience/qualifications
• Past performance/references
• Plan methodology/project approach
• Quality of responsiveness of proposal
• Cost evaluation
Staff selected the proposed consultant within the guidelines of the State of California Government Code and the City’s Purchasing Ordinance. The final ranking of the firms is shown below.

Staff is also adding a design contingency for other components such as accessible curb ramps, pavement rehabilitation, or relocation of sewer utilities that may be required as the design team and City team work on putting the plans together. Any additional tasks that may be issued using the contingency will be performed in accordance with purchasing policies. This contingency will provide staff the opportunity to add to the design as necessary to have a complete streets project for the community. Contingency funds not used will be returned to the fund balance.
