CITY OF YUBA CITY
STAFF REPORT
Date: June 16, 2026
To: Honorable Mayor & Members of the City Council;
From: Finance/IT Department
Presentation By: Kaylayshia Byrd, Administrative Analyst II Summary
Subject: Purchasing Policies and Procedures Manual Revisions Recommendation: Adopt a Resolution approving the revised City of Yuba City Purchasing Policies and Procedures Manual and authorize the City Manager to implement and administer the updated policies and procedures
Fiscal Impact: There is no fiscal impact
Purpose:
To adopt revisions to the City of Yuba City Purchasing Policies and Procedures Manual to improve procurement efficiency, clarify purchasing authorities and administrative procedures, update procurement requirements, and ensure continued compliance with applicable laws and City purchasing practices.
Strategic Focus Area:
This staff reports supports the City Council’s strategic goal of Fiscal Responsiblity.
Background:
In January 2022, the City Council adopted comprehensive revisions to the City's Purchasing Policies and Procedures Manual to formalize purchasing practices, clarify procurement responsibilities, and update approval thresholds. Since implementation, staff have continued to evaluate procurement processes and identified opportunities to further improve efficiency, clarify administrative procedures, and align the policy with current operational practices.
The proposed amendments update procurement procedures, clarify purchasing authorities and approval processes, revise administrative provisions, and incorporate operational improvements identified through the City's ongoing use of the policy.
Analysis:
The City's Purchasing Policies and Procedures Manual establishes the framework for the procurement of goods and services, defines approval authorities, and provides guidance to City staff regarding purchasing requirements and internal controls.
Since the last comprehensive update, staff have identified opportunities to improve administrative efficiency, clarify procurement procedures, and align the policy with current operational practices. The proposed amendments provide additional clarification regarding procurement documentation, purchasing authorities, contract administration, approval workflows, and internal processing requirements.
The revisions also clarify procedures related to the administration of executed agreements and associated purchase orders. Under the proposed amendments, purchase orders issued pursuant to an agreement that has already been approved and executed by the authorized approving authority may be processed through established departmental authorization procedures, eliminating redundant approval steps while maintaining budgetary controls, contract limits, and existing approval thresholds.
Staff believes the proposed amendments will improve procurement efficiency, reduce administrative processing time, and maintain appropriate accountability and oversight for City expenditures.
Fiscal Impact:
There is no fiscal impact.
Alternatives:
1. Adopt the Resolution approving revisions to the Purchasing Policies and Procedures Manual as presented.
2. Direct staff to modify the proposed revisions and return with a revised Purchasing Policies and Procedures Manual for future Council consideration.
3. Decline to adopt the proposed revisions and maintain the current Purchasing Policies and Procedures Manual.
Recommendation:
Adopt a Resolution approving the revised City of Yuba City Purchasing Policies and Procedures Manual and authorize the City Manager to implement and administer the updated policies and procedures.

6 SECTION 8: PROCUREMENT PROCEDURES
The primary purchasing objective is to obtain suitable goods, services, and construction at economic prices, as these acquisitions are direct costs to the taxpayer. The Municipal Code and purchasing policy require competition for all purchases over $5,000 and sealed competitive bids for over $100,000.
1. Bidding limits are generally “per order,” and orders are not to be split to circumvent the specified limits.
2. The estimated full-value cost of the item plus tax before any discount is the amount to be considered in determining bidding requirements. Even though the net purchase price could be lower than the bid thresholds, the asset value would be the full price of the item.
All purchases of supplies, equipment, and technical/maintenance services which qualify as part of a public project as defined by the Uniform Construction Cost Accounting Act shall be made in accordance with the Public Contract Code and Municipal Code Section 2-6.02. (see Section 5).
8-1. Informal Procurement:
The bidding limits below refer to supplies and technical/maintenance services and do not include professional/consultant services (see Section 10) or “public projects” (see Section 5). The bidding limits are below.

8 8-2.1. Formal Bids:
Formal quotations are written bids or proposals requiring a formal closing time/date. Public notices are posted on the City’s website and/or advertised in the local newspaper, at least ten days prior to the opening of the bids. When advertised in the newspaper, invitations for bid will be published at least two times. Formal bids are opened in public. 8-2.2. Formal Proposal Process:
The formal proposal process may be used in procurements involving complicated and performance-type specifications which may require involved negotiations or communications with vendors to clarify proposals submitted. The proposal process should be utilized in negotiated procurements or those procurements where the answer to a certain approach or a specific item necessary to satisfy the City’s needs is unknown. Public notice advertisements requesting invitations for proposal will be posted on the City’s website and/or published in the local newspaper at least two times; the first insertion must be at least ten days prior to the opening date. Formal proposals are made public upon execution of a signed contract.
8-2.3. Lowest Responsible Bidder:
Bids will be awarded to the responsive bidder who submits the lowest responsible bid that is most advantageous to the City and is consistent with the requirements of this procurement policy. The term “lowest responsible bidder” as used in the City’s bidding documents shall mean the lowest bidder whose offer best corresponds in quality, fitness, and capacity to the requirements of the proposed work or usage.
Sellers, vendors, suppliers, and contractors of supplies and equipment who maintain places of business located within the limits of the City shall be given preference if quality, price, and service are equal. In awarding the purchase, staff may consider the benefit derived by the City from sales tax revenues received by it in tabulating the lowest responsive bidder.
In determining the “lowest responsible bidder,” the following elements shall be given consideration (in addition to price):
1. The ability of the product offered to provide the quality, fitness, and capacity for the required usage.
2. The ability, capacity, and skill of the bidder to perform the contract or provide the service required.
3. The character, integrity, reputation, judgment, experience, and efficiency of the bidder, particularly with reference to past purchases by the City.
4. Whether the bidder can perform the contract and/or deliver the materials, supplies, and services within the time required.
5. The quality of performance and/or quality of products provided in previous contracts or services.
9 6. Other information secured and having a bearing on the decision to award the contract.
7. Continuity of service.
8-2.4. Responsiveness:
A responsive bid is one which is in substantial conformance with the requirements of the invitation to bid, including specifications and the City’s contractual terms and conditions.
Bidders who substitute terms and conditions or who qualify their bids in such a manner as to nullify or limit their liability may be considered a non-responsive bidder and reject on those grounds. Conformance with the requirements of the invitation to bid may also include, but is not limited to, completion of forms, inclusion of references and attachments, and completion of required responses.
8-2.5 Rejection of Bids/Proposals:
The authority to reject is based on the authority to award. The City of Yuba City reserves the right: (1) to reject any or all bids or any part thereof and (2) to waive any informalities and/or negotiate minor deviations to the bid with the successful firm. The City of Yuba City’s decision shall be final.
8-2.6. Late Formal Bids/Proposals:
Formal bids or proposals submitted after the designated closing time shall be returned unopened and not accepted.
8-2.7. Tie Bidders:
If two or more bids are received which are in all respects equal, the City Council may award to the local vendor. If both are local vendors or none are local vendors, City Council may draw lots, re-bid, or the award may be made to the one deemed in the best interest of the City.
8-3. Technical/Maintenance Services:
Services of a general nature (as opposed to professional/consulting services) shall be contracted by following a Request for Proposal or Bid process. The method of selection shall be determined by the Purchasing Officer and may include both qualification of the service provider and cost of the service. If it is determined by the operating department in consultation with the Purchasing Officer that all vendors providing a service classification can equally provide the service satisfactorily, a bid process would be appropriate; however, if factors other than price need to be considered in awarding the contract, a proposal process may be used.
Proposals evaluated by the City for technical/maintenance services should be based on a combination of qualifications and cost. Examples of areas other than price that may be
