CENTRAL SAN BOARD OF DIRECTORS POSITION PAPER MEETING DATE: JUNE 16, 2022 SUBJECT: CONDUCTA PUBLIC HEARING TO CONSIDER ADOPTING UNCODIFIED ORDINANCE NO. 325 TO ESTABLISH THE "CENTRAL SAN STANDARD SPECIFICATIONS FOR DESIGNAND CONSTRUCTION, 2022 EDITION"AS DISTRICT'S STANDARD SPECIFICATIONS, IN ACCORDANCE WITH DISTRICT CODE SECTION 9.08.010, TO BECOME EFFECTIVE JULY 1, 2022 SUBMITTED BY: INITIATING DEPARTMENT: DANA LAWSON, SENIOR ENGINEER ENGINEERING AND TECHNICAL SERVICES- PDS-DEVELOPMENT SERVI CES-MAI NLI NE REVI EW REVIEWED BY: DANEA GEMMELL, PLANNING AND DEVELOPMENT SERVICES DIVISION MANAGER JEAN-MARC PETIT, DIRECTOR OF ENGINEERING AND TECHNICAL SERVICES Roger S. Bailey Kenton L. Alm General Manager District Counsel ISSUE Section 9.08.010 of the District Code requires that the Board of Directors'adopt an uncodified ordinance to establish or amend the District's standard specifications. BACKGROUND Central San's Standard Specifications for Design and Construction was last updated in 2020. Since that document was published, staff has continued to solicit comments from internal and external customers, June 16, 2022 Regular Board Meeting Agenda Packet- Page 408 of 771 Page 2 of 297 and has revised the document to clarify requirements and align with industry practices. The updated document is now ready for publication. Section 9.08.010 of the District Code requires that the Board of Directors amend the standard specifications by uncodified ordinance for an effective date of July 1, 2022. ALTERNATIVES/CONSIDERATIONS The Board could decline to adopt the 2022 edition of the standard specifications, which would result in the 2020 edition continuing to be enforced. However, this is not recommended since it is important that the most current practices be covered by a Board-established specifications document. FINANCIAL IMPACTS None by this action. Design and construction of new facilities in accordance with the proposed specifications will minimize future maintenance costs and ensure that the facilities have an acceptably long service life. COMMITTEE RECOMMENDATION The Engineering and Operations Committee reviewed this item on June 1, 2022, and recommended holding the public hearing. RECOMMENDED BOARD ACTION Conduct the public hearing, and adopt an uncodified ordinance to establish the document entitled Central San Standard Specifications for Design and Construction, 2022 Edition as Central San's standard specifications, in accordance with District Code Section 9.08.010, to become effective July 1, 2022.
