The results required a significant increase in the recommended <br />capital improvement program to address existing and future growth and pipeline capacities. This <br />new update identified approximately $45,281,000 of recommended capital improvements to the City’s <br />wastewater collection system. Based on priority rankings, approximately $14,242,000 of capital projects <br />were ranked in the highest priority categories (1 and 2). This means that the flow model projected <br />potential overflows under existing conditions. Despite this information, the City has not experienced any <br />overflows as projected by the model in those locations. The City has been proactively conducting closed- <br />circuit television inspections of the wastewater collection system to assess the conditions to identify <br />sources of infiltration and inflow into the City’s sewer system. Reductions in infiltration and inflow could <br />reduce the potential overflow conditions and may also reduce the need for the capital improvements <br />identified in the updated master plan. <br /> <br />The City currently anticipates funding its collection system capital needs on a pay-as-you-go, cash basis, <br />and has increased its sewer rates accordingly. However, the City might consider the future use of debt <br />financing if such financing was either needed to fund high-priority projects or if it made economic sense <br />to construct a number of improvements in a given year rather than spread the capital improvement <br />expenditures over a longer timeframe3 <br /> <br />VIII-3 References <br />• City of Redwood City Sewer System Master Plan, January 2013, West Yost & <br />Associates, Inc. <br />• Redwood City Sewer System Master Plan Final Report August 2008, RMC Water <br />and Environment <br /> <br /> <br />3 Appendix A, Information About Redwood City’s Wastewater System <br />6.2.A. - Page 58
