<br /> <br />City of Redwood City Page 52 <br />Sewer System Management Plan, March 2018 Element IX <br />The City’s Public Works Superintendent is responsible for communicating the results of the <br />Annual SSO Report to the Assistant Public Works Director and to the City Council. Based on the <br />results of the internal Annual SSO Report, the Public Works Superintendent and Utilities Field <br />Supervisor will evaluate if opportunities for improvement exist in the SSMP and if modifications <br />are necessary to improve the effectiveness of the SSMP implementation. The evaluation is <br />documented using the Annual SSMP Evaluation Form Appendix IX-2. Necessary updates to the <br />SSMP are made based on these annual evaluations. A record of changes to the SSMP since last <br />certification indicating when a subsection of the SSMP was changed and/or updated and who <br />authorized the change or update is included in Appendix J: SSMP Change Log. <br />The City has developed historical perspectives of the collection systems performance for the past <br />five fiscal years through 2016/17. Appendices IX-3 to IX-9 contains a separate page for each of <br />the following performance results including a table of the information and a graph of the <br />important results from the historical data: <br />IX-3 Sewer Overflows by Fiscal Year <br />IX-4 Number of SSOs by Volume Size <br />IX-5 SSO Volume Information <br />IX-6 SSOs by Cause <br />IX-7 SSOs by Category of SSO <br />IX-8 Comparative SSO Rates/100 Miles <br />IX-9 SSOs by City Facility <br />IX-2 Performance Monitoring and Program Changes <br />The City will evaluate the performance of its wastewater collection system at least annually <br />using the performance measures identified in Section IX-1 above. The City will update the data <br />and analysis at the time of the evaluation and will place the annual performance report in <br />Appendix F, IX-2 of the SSMP. <br />The City may use other performance measures in its evaluation. The City will prioritize its <br />actions and initiate changes to this SSMP, its operations and maintenance practices, and any <br />related programs based on the results of the evaluation. This will be done as part of the annual <br />self-audit (see Element X). <br />IX-3 References <br />The data used in this section and the Element IX Appendix F were taken from the following <br />references: <br />• City collection system records <br />• CIWQS SSO data as of as of June 30, 2017 <br /> <br />6.2.A. - Page 60
