OPERATIONS AND MAINTENANCE PROGRAM © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for San Leandro use only. Page 23 of 57 4. Operation and Maintenance Program WDR REQUIREMENTS Att. D-4 (pg. D-4) “The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.” 4.1. Updated Map of Sewer System WDR REQUIREMENTS Att. D-4.1 (pg. D-4) “An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.” COMPLIANCE The City maintains up-to-date maps of its sewer system. Each of the City’s 184 base maps are digitized and formatted into an ArcGIS based mapping system. The ArcGIS mapping system is linked to the Collection Department CMMS program, a street directory, and CCTV inspection Records. The link allows the map to be populated with key data such as pipe size and pipe length. The maps show gravity line segments, force main segments, manholes, lift stations, stormwater conveyances, City/District boundaries, and valve boxes. Information Technology provides updated map pages to all map holders on a regular basis. Maps are continuously updated by Engineering as new tracts are accepted, and map corrections are identified by the collection crew based upon field observations. If field staff find a mapping error, they will notify Engineering, who makes the update. Simple updates (i.e., manhole placement) are completed immediately, while more complex updates (i.e., force main location) take longer. Upon request, the City will provide the system maps to State and Regional Water Board staff. EFFECTIVENESS The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element: • Were all map updates completed in a timely manner? • Are all staff trained in the procedure for providing map update information? • Are newly installed sewer assets incorporated into the system maps? • Are there terrain features or assets that should be incorporated in future map updates (e.g. exposed pipe, siphons, ARVs, surface water, etc.)
