SYSTEM EVALUATION, CAPACITY ASSURANCE, CAPITAL IMPROVEMENTS © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Redwood City use only Page 44 of 59 COMPLIANCE The above requirements are addressed below: a. The City’s collection system evaluation involves every component of the City collection system, including pipelines, manholes, and pump stations. The assessment of pipeline condition is the most significant condition assessment responsibility the City has. It is of key importance to regularly perform pipeline condition assessments to initially establish a baseline condition and to monitor changes over time. The City hires a contractor to complete CCTV inspections and evaluate collection system assets using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) and Manhole Assessment Certification Program (MACP). The City assesses the condition of laterals with own crew using push cameras and pole cameras which can be dropped into manholes. In addition, the City has nine smart covers on manholes within the sewer system. b. The City currently completes a CCTV condition assessment of the entire collection system every ten years using contracted services. In 2024, 19 miles of line (equivalent to 10% of the system) were inspected by CCTV. The City continues to strive to reduce the number of spills and is therefore evaluating its inspection and maintenance intervals on all work activities to help determine the optimal schedule for CCTV assessment. In 2024, 60 miles of line (equivalent to 33% of the system) were cleaned. The City’s historical records indicate that it is not necessary to prioritize the assessment of pipes that have a high consequence of environmental impact. However, the City is in the process of evaluating its risk matrix for pipelines that are near surface water. c. The City assesses system conditions using visual observation, video surveillance, smart covers on manholes, pole cameras, and contracted CCTV camera service. The City’s collection system includes pipes which run underground in unimproved areas (i.e., fields). Most of these pipes are visually inspected on an annual basis as part of the hot spot list for annual cleaning. d. The City has identified areas of infiltration into their system and has identified those facilities that are near surface water. These areas were included in the City’s CIP plan risk assessment. e. The City documents all inspections, maintenance, and evaluations of the sewer system. These documents are maintained at City offices or in the Hiperweb program, as required by City’s retention schedule. The City considers direct and indirect impacts of climate change such as sea level rise, flooding, increased erosion, and wildfires on its collection system assets. The City aims to design collection system assets such as pump stations to be equipped for resiliency against power disruptions by including backup permanent onsite generators and a redundancy connection for portable generators. The City also recognizes and considers the role of levees in protecting collection system assets in certain areas of the City, such as in Redwood Shores. The City will continuously monitor for change and evaluate the potential impacts of climate change during each audit. If potential impacts are identified, appropriate action will be taken and the SSMP will be updated. EFFECTIVENESS The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element: • Has the City maintained its schedule for inspecting the sewer assets listed below and is data being reviewed in a timely manner? o CCTV Gravity Mains o Laterals ATTY/RESO.0077/CC RESO SEWER SYSTEM MANAGEMENT PLAN - EXHIBIT A REV: 07-14-25 LF Page 51 of 317
