Methods of Procurement

The District’s methods of procurement include the following: purchase orders, contracts, agreements, and leases. Depending on the District’s requirements, a purchase order or a specific type of contractual document will be issued. Standard District terms and conditions typically accompany all procurements.

Authorized Procurements

All procurements made by the District require the issuance of a purchase order, contract, or agreement. Each procurement instrument will have a unique document number. Referencing the procurement document number is essential when conducting business with the District, and must be included on all vendor invoices and shipping documents. Proceeding without the appropriate procurement instrument may result in a rejected shipment or invoice.

Basis for Award

Public Record

With limited exceptions, records generated by or in the possession of the District are subject to the Public Records Act, California Government Code Section 6250 et. seq. As such, documents submitted to the District by a vendor are subject to disclosure to the general public.


When the vendor’s personnel or their subcontractors enter District property to repair, install, service, maintain, construct or consult, the District requires that the vendor provide insurance documents, including Certificates of Insurance and Endorsements, verifying sufficient coverage. Typical insurance coverage includes, but is not limited to: general liability, automobile liability, workers’ compensation, and professional liability (where applicable).


Requirements for delivery are specified in all requests for bids/proposals, on all purchase orders, and in all contractual documents. The respective purchase order or contractual document number MUST appear on all shipping documents. Failure to do so may result in rejection of the shipment or a delay in payment.


Payment will be made only after delivery has been affected, the goods or services have been accepted, and the vendor’s invoice has been received. The District’s payment terms are net 30 days after receipt of invoice unless otherwise specified on the respective purchase order or contractual document.

Gifts and Gratuities

The District recognizes the responsibility of all of its employees to maintain positive relationships with all its vendors and believes this can be accomplished in a professional manner without gifts or gratuities interfering with and/or influencing employees. The District maintains a policy expressly prohibiting the acceptance of gifts or gratuities from any existing or potential vendors. Vendor compliance with this policy is appreciated.
