DISCUSSION
Background
The Parks Section of the Public Works Department is responsible for managing irrigation and well pump repairs at City facilities, including, but not limited to, parks, greenbelts, and street landscaped areas. On March 12, 2024, bids were solicitated to 10 vendors. On March 25, 2024, one bid was received from Cornerstone of Concord, CA.

On December 24, 2024, Public Works executed CCO No. 1 with Cornerstone, in the amount of $30,000, to provide adequate purchasing authority due to additional repairs needed for aging equipment.
On March 27, 2025, a car accident caused damage to the booster pump, backflow, bollards, and underground piping on Airport Way and Michael Avenue. Cornerstone evaluated the damage and provided a quote for the repairs needed to restore the streetscape irrigation along Airport Way.
Present Situation
The Parks Section of the Public Works Department is responsible for managing irrigation and well pump repairs at City facilities, including, but not limited to, parks, greenbelts, and street landscaped areas. On March 12, 2024, bids were solicitated to 10 vendors. On March 25, 2024, one bid was received from Cornerstone of Concord, CA.
Council approval is needed for CCO No. 2 with Cornerstone because the cumulative amount of CCO No. 2 exceeds the administrative change order authority allowed under the existing contract. CCO No. 2 will ensure adequate funding is available for the current known repairs and for any unanticipated repairs that will continue through the duration of the contract.
The revised contract amount, including previously approved CCOs, will be $150,000.
It is recommended that Council approve CCO No. 2, in the amount of $60,000, with Cornerstone for the On-Call Parks Pump Repairs, Project No. OM-24-080 (Attachment A).
Findings
Pursuant to Stockton Municipal Code (SMC) section 3.68.070, Council may approve findings which support an exception to the competitive bidding process. These findings include:
1. The City does not have the internal resources to diagnose and repair wells and booster pumps at City streetscape locations and parks.
2. The City must continue to irrigate parks, greenbelts, and landscaped street areas.
3. This bid was originally solicited as an informal bid, under $100,000 not requiring Council approval. Due to the volume of damages, the contract amount will now exceed $100,000 and requires Council approval.
FINANCIAL SUMMARY
There is sufficient funding in the Public Works Parks General Fund and Landscape Maintenance District Operating Budgets to approve CCO No. 2 with Cornerstone in the amount of $60,000. With the approval of CCO No. 2, the total revised contract amount with Cornerstone will be $150,000.
