IN RESPONSE TO REQUEST FOR PROPOSAL NUMBER 1859 FOR RIVERSIDE PUBLIC UTILITIES ANNUAL GROUNDWATER ASSESSMENT REPORT FOR 2018 IN AN AMOUNT NOT TO EXCEED $102,140 ISSUE: Approve a Supplemental Agreement in response to Request for Proposal Number 1859 for Riverside Public Utilities Annual Groundwater Assessment report for 2018 with Water Systems Consulting, Inc., of Rancho Cucamonga, California, in an amount not to exceed $102,140. RECOMMENDATIONS: That the Board of Public Utilities: 1. Approve a Supplemental Agreement in response to Request for Proposal Number 1859 for Riverside Public Utilities Annual Groundwater Assessment report for 2018 with Water Systems Consulting, Inc., of Rancho Cucamonga, California, in an amount not to exceed $102,140; and 2. Authorize the City Manager, or designee, to execute the Supplemental Agreement with Water Systems Consulting Inc., including making minor and non -substantive changes and to sign all documents and instruments necessary to complete the transactions. BACKGROUND: The City of Riverside Public Utilities Department (RPU) provides potable water to 65,000 service connections, which serves over 310,000 people in the community. RPU currently owns and operates over 50 groundwater production wells and has been obtaining 100 percent of its water supply from local groundwater basins since 2008. RPU has approximately 55,000 acre feet (AF) of extraction rights from the San Bernardino Basin Area (SBBA), about 28,000 AF from the Riverside Basin, and 2,700 AF from the Rialto -Colton Basin. General conditions in these basins are dynamic and influenced by many factors, most of which are outside of RPU's control. Throughout the year, RPU staff measure water levels and collect water quality data at production and monitoring wells across the three (3) groundwater basins to monitor current conditions. Groundwater data collected by the United States Geological Survey (USGS) as well as by other water agencies is also tracked to gain a further understanding of the basins. Over the last 20 years, groundwater levels in these basins are continuing to show a long-term declining trend. This negatively impacts RPU's production capacity and increases the cost to produce groundwater.
