CITY COUNCIL REGULAR MEETING SUPPLEMENTAL MATERIALS 6-2-26

SUPPLEMENTAL MATERIAL 1 Responses to City Council Agenda Items – June 2, 2026 Regular Meeting Agenda Item #11: Approve the proposed Sewer Rate Structure, Sewer Rate, and updated Sewer Connection Fees to support implementation of the Sewer Rate Study's Financial Plan Scenario 1 - Maintain 1.Last November, the projected failure rate of the system was based on closed- circuit television (CCTV) inspections. At that time, only about 30% of the system had been inspected by CCTV, so the condition of the remaining 70% of the system was an estimate. I’m assuming CCTV inspections are continuing, has the failure or condition rate changed since those additional inspections? (Note this was meeting held on 11/4 and was an item continued from 10/21). A.Since November, Public Works has continued its annual sewer cleaning and CCTV inspection program, which targets approximately 190,000 linear feet of sewer main each year. This ongoing effort allows the City to complete a full inspection cycle of the sewer collection system approximately every seven years. As additional CCTV inspections have been completed, staff has gathered more detailed condition information on the sewer system. Based on the inspections performed to date, there has not been a significant change in the overall projected condition or failure rate of the system compared to what was presented in November. As a result, the assumptions used in the sewer rate study and the recommended Maintain Scenario remain valid. While the overall system condition has remained generally consistent with previous projections, the additional inspections have enabled staff to better identify and prioritize specific locations requiring rehabilitation or replacement. For example, recent CCTV inspections identified additional deteriorated sewer main segments along Denker Road that warrant replacement. To address this deficiency and reduce the risk of future failures, approximately $1.09 million has been included in the FY 2026/27 Capital I mprovement Program for sewer main replacement in this area. Staff will continue to perform CCTV inspections and condition assessments to refine project priorities, improve asset management planning, and ensure that capital investments are focused on the highest-risk portions of the system.
