San Dimas adopts ordinance updating sewer code to align with county rules
Summary
The council adopted Ordinance 1330 (MCTA 25-04) to amend Chapter 14.08 of the municipal code to adopt Los Angeles County sanitary sewers and industrial waste ordinance by reference and to update administrative details; staff said the city must maintain a sewer system management plan to avoid State Water Board fines.
The San Dimas City Council adopted Ordinance 1330 on July 22, approving Municipal Code Text Amendment 25-04 that updates Chapter 14.08 to adopt Los Angeles County’s sanitary sewers and industrial waste ordinance by reference and to clarify administrative recordkeeping language.
Grant Garcia, a management analyst in Public Works, told the council the city owns approximately 103 miles of sewer line and that the State Water Board requires a current Sewer System Management Plan (SSMP) that must be updated every five years. Garcia said council previously approved an updated SSMP on June 24, 2025 and that without a valid SSMP the city could be subject to monetary fines.
"These edits clarify the city adopts the LA County sanitary sewers and industrial waste ordinance by reference and that it is still current," Garcia said, summarizing the minor revisions staff proposed.
No members of the public spoke during the ordinance public hearing. The council moved to adopt the ordinance on second reading and recorded the item as passing (the minutes show the motion passed with four votes in favor and one recusal). Staff reported no additional fiscal impact associated with the code edits.
Ordinance 1330 will update the municipal code to reflect current county-adopted standards and to ensure the city remains compliant with State Water Board requirements for sewer system oversight.
