Art Chianello, stated we are at 55% water year and the City's water entitlement supply this year is being distributed to three water treatment plants, prior obligation demands, evaporation losses which occur within Lake Isabela, and water for City facilities. For Board Information only, no action taken, B. Update on Water Usage in the City's Domestic Water Service Area Jason Meadors, Water Resources Director, presented a brief report and reviewed the Domestic Water Use Comparison and Metered Percent Reduction graphs. Mr. Meadors stated On April 7, 2017 the Governor ended the Drought State of Emergency for California's water purveyors. From May 2017 through April 2018 the City's Domestic Water Service Area had a cumulative water conservation savings of approximately 9%. Also during this time, the City's domestic water system increased in size by approximately 11 %. The City is still recommending that conservation efforts continue due to historically low groundwater levels and uncertainty of future water supplies, For Board Information only, no action taken. C. Update on the TCP Mitigation Project Jason Meadors, Water Resources Director, gave a report and stated on July 18, 2017, the State Water Board adopted a new maximum contaminant level (MCL) for the groundwater contaminant 123 - Trichloropropane (TCP). The new MCL went into effect January 1, 2018, The City turned off all TCP affected wells. Last summer the City started the process of sampling and equipping Group 1 (27 wells) with TCP treatment utilizing a contract with W.M. Lyles. Currently some of the Group 1 (27 wells) are operating and water demands are being met by existing unaffected wells; Group 1 wells where construction is complete and are operating; and the surface water treatment plants. Construction of all of the Group 1 (27 wells) should be completed by the end of June, with one remaining Group 1 well to be completed in July. Cal Water has done a good job operating the City's system. Surface water is being used in our system to supplement offline wells, Eighty-four treatment vessels have been installed to date and 60 of these vessels have been loaded with the treatment media called granular activated carbon (GAC). Sampling of the wells and vessels take place in a sequential order of construction completion, Phase 2 of this project includes eight additional wells. The scheduled completion date for the remaining eight wells is November 2018, The project is going well and the City is complying with all drinking water standards. 6. NEW BUSINESS - None 7.

A. TO: Bob Smith, Chairman Jacquie Sullivan, Member Ken Weir, Member FROM: Art Chianello, Water Resources Manager DATE: June 6, 2018 APPROVED DEPARTMENT HEAD SUBJECT: Update on the Kern River North and South Levee Accreditation by the U.S. Department of Homeland Security Federal Emergency Management Agency (FEMA) RECOMMENDATION: Item for Board Information only. BACKGROUND: The Kern River Levee District was formed in 1928 with the single responsibility to operate and maintain a levee system along the Kern River through Bakersfield. On March 28, 2000 the Local Agency Formation Commission approved the merger of the Kern River Levee District with the City of Bakersfield and establishment of a Subsidiary District. The attached map shows the location of the river levees. The purpose of the Kern River levee system is to hold back and contain high river flows and prevent flooding of developed areas. The Flood Map Modernization program, a multi-year Presidential initiative funded by Congress from 2003 to 2008 called for the nation's flood maps to be improved and updated. On April 23, 2007, the U.S. Department of Homeland Security notified the City of Bakersfield and the County of Kern that FEMA was in the process of the Flood Map Modernization Program. The existing Kern River levees, at the time of this notification, were accredited by FEMA for the 100 year flood event. During the Map Modernization process, FEMA would continue to accredit the levee as a Provisionally Accredited Levee system (PAL). It was the City's responsibility to provide data and analysis to FEMA so that once approved, FEMA could permanently accredit the Kern River South levee for providing protection against the 100 year flood event. The portion of the South Levee that required re -accreditation was between one mile west of Ming Avenue to Golden State Avenue. Levee data, flood model analysis, and geotechnical reports were submitted to FEMA in July 2011. The re -accreditation process for the South Levee was completed, as described in the attached letter dated September 3, 2015 from FEMA. According to the letter, the Kern River South Levee meets the minimum certification criteria outlined by the Code of Federal Regulations. FEMA continued to accredit the levee system on the subsequent Flood Insurance Rate Map (FIRM) update as providing protection from the 100 year flood. The accreditation allows insurance companies to set reasonable rates and premiums for properties with the area protected by the levee. SAKE[ OF M oO PORA ,rs� ADMINISTRATIVE REPORT WATER BOARD �RLIFO Nl Back in March 2018, FEMA contacted the City of Bakersfield and wanted to meet with City staff to provide an update on the FEMA Kern River Flood Hazard Study. The City and FEMA met and discussed FEMA's analysis and mapping for non -accredited levee systems in the Bakersfield area. The purpose of the meeting was to discuss updated flood hazard data and non -accredited levee approach for the Flood Insurance Study (FIS) and the FIRMS for Bakersfield. FEMA wanted input from the City on unique conditions of our levee system and wanted to collect any existing data that will impact their analysis and mapping. FEMA reviewed Bakersfield's certified levees and non -certified levees. FEMA determined that a portion of the City maintained levee system located between Golden State Avenue and Manor Street must be certified or mapped as a non -accredited levee to reflect the risk of being non- accredited. The process to certify the levee systems from Golden State Avenue to Manor Street would be the same process that the City went through with FEMA for the South Levee reach located downstream. Initial Modeling was done in August 2017 by FEMA. In March a levee Kickoff meeting was held between FEMA, their consultants, Kern County, and the City. At that meeting the City learned that it must certify the non -accredited levees before new preliminary FIRMS are issued so that insurance rates in high risk areas (associated with the non -accredited levees) are not impacted. The levees that are currently non -accredited were identified by FEMA when they obtained updated survey data and ran a new hydraulic analysis model of the Kern River. According to FEMA, due to construction of projects downstream the stretch of river channel between Golden State Avenue and Manor Street, the river in that reach has less conveyance capacity that was present when the City ran the last hydraulic mode. When the City modeled the river channel and the levees along this reach of the river back in 2011, it was determined at that time that the 100 year flood elevation did not touch the base of the levee and therefore it was not required that the levees be recertified. Now with the new model run by FEMA, it has been determined that the 100 year flood will touch the levees and will need to be recertified so that the FIRMS are not impacted. The City has reviewed FEMA's model and confirmed that it is correct. FEMA has determined that the levees (North and South levees) from Golden State Avenue to Manor Street are eligible for 'provisional accreditation' and, therefore, FEMA will be offering the City of Bakersfield this option. This allows the City to apply the same accreditation approach that was used to accredit the south levee in 2015. The Water Resources Department will use an existing active agreement with consultant Meyer Civil Engineering for this levee recertification work. Meyer Civil Engineering assisted with the successful accreditation process for the south levee in 2015. 2.20.030 Water board duties. The city council for the city delegates to the water board for the city the power to maintain and keep in repair all things reasonable or convenient for the protection of the lands of the Kern River Levee District from overflow and for the purpose of conserving or adding water to the sloughs and drains in the district. The water board shall also, on behalf of the Kern River Levee District and the city council, cooperate with the United States, the state of California, or any department or agency of either, in order to accomplish any of the purposes of the district. In all other matters, the water board will make recommendations to the city council for action, and all powers not listed herein are reserved to the city council.

Director, Water Resources Department City of Bakersfield 1000 Buena Vista Road Bakersfield, CA 93311 Dear Mr. Meadors: U.S. Department *f Homeland Security I I I I Broadway, Suite 1200 Oakland, CA. 946074052 6-w4 "%War FEMA ECEIVE SEP 0 8 2015 CITY WATER RESOURCES This correspondence is in reference to the July 28, 2011, July 9, 2014, February 6, 2015, and April 20, 2015, letters and data submissions to the U.S. Department of Homeland Security's Federal Emergency Management Agency (FEMA). This documentation was regarding certification of the Kern County Levee IDs 8, 9, 10, 13, 14, 15, 18, 99, 100, 200, and 20I for the Kern River South Levees in order to meet the criteria of the Code of Federal Regulations, Title 44, Section 65.10 (44 CFR 65.10). The submitted data has been reviewed, and the levees are considered accredited. The pertinent information regarding this levee system is listed below. Identifier: Kern River South Levees (Kern County Levee IDs 8, 9, 10, 13, 14, 15, 18, 99, 100, 200, and 201) Flooding Source: Kern River FIRM Panels Affected: Kern County and Incorporated Areas FIRMS 06029C 1818E, 06029C2257E, 06029C2275E, 06029C2276E, 06029C2277E, and 0602902281 E dated September 26, 2008 In support of the levee certification, the following information was submitted: I . A levee certification report prepared by Meyer Civil Engineering, Inc. titled, "City of Bakersfield, Kern River South Levee - Greater Bakersfield, Levee Certification Report - July 28, 2011." 2. A revised levee certification report prepared by Meyer Civil Engineering, Inc. titled, "City of Bakersfield, Kern River South Levee - Greater Bakersfield, Levee Certification Report - July 7, 2014." 3. A letter dated February 6, 2015 from Richard Meyer, Meyer Civil Engineering, Inc., and supporting data responding to FEMA's November 14, 2014, comments. 4. A letter dated April 20, 2015 from Richard Meyer, Meyer Civil Engineering, Inc., and supporting data responding to FEMA's April 17, 2015, comments. Mr. Jason Meadors, P.E. September 3, 2015 Page 2 The above documentation and data have been reviewed, and based on receipt of this information, the Kern River South Levees (Kern County Levee IDs 8, 9, 10, 13, 14, 15, 18, 99, 100, 200, and 201), meet the minimum certification criteria outlined in 44 CFR 65.10. Therefore, we plan to continue to accredit this levee system on the next Flood Insurance Rate Map (FIRM) update as providing protection from the 1 -percent -annual - chance (base) flood. The area protected from the base flood by this levee will be mapped as a shaded Zone X, and a note will be placed warning of the flood risk that still exists. Please be advised that levee systems, and the estimated level of protection provided by these systems, can and do change with time. Future map updates may require the levee system to be certified again at the time of update. Also, design, construction, operation, and/or maintenance documents may be requested at any time. Deviations from the documentation and data submitted to FEMA could result in the levee system no longer being mapped as providing protection from the base flood on future FIRMS. If at any point additional information is provided to FEMA that shows the levee system no longer meets certification criteria as outlined in 44 CFR 65. 10, we will contact the levee owner and community about the possibility of de -accrediting the levee system. Thank you for your cooperation. If you have additional questions regarding this matter, please contact me, either by telephone at (510) 627-7274, or by email at robert.bezek@fema.dhs.gov.
