Recommendation Approve Redding Electric Utility's updated and revised 2025 Wildfire Mitigation Plan pursuant to California Senate Bill 901. Fiscal Impact There is no fiscal impact related to approving revisions to the 2025 Redding Electric Utility (REU) Wildfire Mitigation Plan (WMP). Alternative Action The City Council (Council) could choose not to approve the WMP revisions and provide alternative direction to staff. Background/Analysis California Senate Bill 901 became law in September 2018. The law requires electric utilities with overhead electrical infrastructure located in high fire threat zones to prepare plans and implement wildfire mitigation efforts. The WMP requirements are codified in California Public Utilities Code (PUC) §8387(b)(2) for local publicly -owned electric utilities. The first program in REU's WMP, the Wildfire Prevention and Improved Response Program, was approved by Council on May 7, 2019..Three additional programs, the Technology Solutions Program, the Distribution 10 -year Capital Improvement Program, and the Emergency Operations Program, were approved on December 3, 2019, along with the plan as a whole. Council approved REU's 2020 Monitoring & Auditing Annual Report of Wildfire Mitigation on December 1, 2020, and the 2021 Monitoring & Auditing Annual Report of Wildfire Mitigation, with the revised 2022 Wildfire Mitigation Plan on December 7, 2021. Each subsequent year the WMP has been presented to Council for approval. Report to Redding City Council May 14, 2025 Re: 9.5(d)-- 2025 Wildfire Mitigation Plan Update Page 2 The 2025 WMP includes revisions and goals achieved from 2024 which includes the 2024 Monitoring and Auditing Report (Appendix E). The 2025 WMP has minor adjustments and highlights several capital project completions and updated target dates. In addition, the 2025 WMP includes the use of enhanced distribution system protection settings to further reduce the risk of wildfire ignition from REU infrastructure during the fire season. Lastly, as part of prudent utility practice, the 2025 WMP provides REU with the ability to pre-emptively de -energize portions of the grid during high fire threat weather events, more commonly known as public safety power shutoffs. If approved, the changes made to REU's WMP will be incorporated and submitted for California Wildfire Safety Advisory Board review. Environmental Review This is not a project defined under the California Environmental Quality Act, and no further action is required.

OVERVIEW A. POLICY STATEMENT REU has been operating its electric system for over one hundred years. System protection for both public and asset safety has been paramount. Given the recent increase in catastrophic wildfires in California, the state passed Senate Bill (SB) 901 in September 2018. The law requires utilities to prepare wildfire mitigation measures if the utility's overhead electrical lines and equipment are located in an area that has a significant risk of wildfire resulting from those electrical lines and equipment. The law requires the wildfire mitigation measures to incorporate specified information and procedures and requires the local publicly owned electric utility, before January 1, 2020, and annually thereafter, to prepare a wildfire mitigation plan. Portions of Redding Electric Utility's 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 2 (REU) electrical infrastructure are located in and adjacent to both California Public Utilities Commission (CPUC) designated Tier 2 and 3 wildfire threat areas. REU's overarching goal is to provide safe, reliable, and economical electric service to its local community. To meet this goal, REU constructs, maintains, and operates its electrical lines and equipment in a manner that minimizes the risk of catastrophic wildfires. B. PURPOSE OF THE WILDFIRE MITIGATION PLAN This Wildfire Mitigation Plan (Plan) describes the range of activities that REU is taking or considering to mitigate the threat of power -line ignited wildfires, including its various programs, policies, and procedures. This plan complies with the requirements of Public Utilities Code section 8387. The Plan is iterative, promotes continuous improvement year -over -year, and represents our best efforts to implement industry best practices in a prudent and reasonable manner in conjunction with various industry associations.

City Objective 5.D: Maintain Emergency Operations Center for coordination of information and resources. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 N 4. City Objective 5.E: Reduce the potential for destructive actions of the fire once ignition occurs, utilizing fire pre -plans, ensuring a properly trained, staffed, and equipped emergency response capability, and timely response to prevent the spread of the fire, minimizing risks to humans and property. a. Action 5.E.1: Ensure that adequate resources are available to pre -plan for incidents that may occur in the very high fire hazard severity zones within the City of Redding. b. Action 5.E.4: Increase staffing of current two -person companies to three- person companies to improve capabilities and initial actions at fire incidences within the community as additional funding becomes available. The City of Redding has been working with the non-profit organization, Community Planning Assistance for Wildfire (CPAW) on a land use planning solution to better manage the City's wildland-urban interface (WUI) and enhance the City of Redding's resiliency to wildfire. The Redding Electric Utility Wildfire Mitigation Plan will assist in linking the recommendations from CPAW and reducing the impacts of wildfires to our community. A. MINIMIZING SOURCES OF IGNITION The primary goal of this Wildfire Mitigation Plan is to minimize the probability that REU's transmission and distribution system may be the origin or contributing source for the ignition of a fire as well as to protect the system from wildfire damage. REU is in the process of evaluating prudent and cost-effective improvements to its physical assets, operations, and training to help meet this objective. REU will implement those changes consistent with this Plan as staffing and budget allows. The secondary goal of this Wildfire Mitigation Plan is to improve the resiliency of the electric grid. As part of the development and ongoing implementation of this plan, REU will assess new industry practices and technologies that will reduce the likelihood of an interruption (frequency) in service and improve the restoration (duration) of service. Other resiliency efforts include mitigating fire fuels located in the WUI and greenbelts likely to be a threat to our facilities and equipment. Additionally, improved fire response will improve resiliency and help avoid the need for public safety power shut off protocols during high fire threat weather. Fire fuels reduction and improved fire response are addressed in the REU Wildfire Prevention Response Program described in Section 5. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 The third goal for the Wildfire Mitigation Plan is to minimize the spread of wildfire within and near REU assets. 1. Strategies The following strategies are part of this Plan and are described in more detail in Section 5. • VEGETATION MANAGEMENT These strategies help to control vegetation near REU overhead transmission and distribution lines so they better adhere to clearance specifications. They also include fire fuels mitigation and other work in order to prevent our system from causing a fire and to protect our system from fire. • ENHANCED INSPECTIONS These strategies consist of assessment and diagnostic activities as well as associated corrective actions. The practices in this category aim to ensure all infrastructure is in working condition and vegetation adheres to defined minimum distance specifications. • SITUATIONAL AWARENESS These strategies consist of methods to improve system visualization and awareness of environmental conditions. The practices in this category aim to provide tools to improve the other components of the plan. • OPERATIONAL PRACTICES These strategies consist of proactive, day-to-day actions taken to mitigate wildfire risks. The practices in this category aim to ensure REU is prepared in high-risk situations, such as dry, windy environmental conditions. • SYSTEM HARDENING These strategies consist of system, equipment, and structure design and technical upgrades. The practices in this category aim to improve system hardening to prevent contact between infrastructure and fuel sources, such as vegetation and animals. It also includes making the system more resilient to wildfire and other disasters. • PUBLIC SAFETY AND NOTIFICATION These strategies will focus on ways to engage the community as partners in preventing and identifying wildfire risk. They include improving outage notification and other items in the interest of public safety. • RECLOSING AND DE-ENERGIZATION These strategies include a discussion of de-energization, disabling automatic circuit reclosing, and fast -trip protection. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 7 • WILDFIRE RESPONSE AND RECOVERY These strategies consist of procedures to react to wildfire or other related emergency conditions. The practices aim to formalize protocols for these situations, so REU can provide an adequate response and recovery. 2. Programs The strategies above will, as budgetary constraints and staffing permit, be developed and implemented through the following programs as part of this Plan and are described in more detail in Section 5. • REU Wildfire Prevention and Improved Response Program • REU Technology Solutions Program • REU Distribution 10 -year Capital Improvement Program • REU Emergency Operations Program REU Wildfire Prevention Strategies and Program Matrix 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 10 1 1 1 1 1 1 -------------------------------- x x Vegetation Management Enhanced x x x Inspections Situational x x x Awareness Operational x x x x Practices System x x x x Hardening Public Safety & x x x Notification Protection x x x x Settings & De- ener ization Wildfire x x x Response & Recovery 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 10 D. IDENTIFYING UNNECESSARY OR INEFFECTIVE ACTIONS The final goal for this Wildfire Mitigation Plan is to measure the effectiveness of specific wildfire mitigation strategies. REU will assess the merits of modifications. This plan will also help determine if more cost-effective measures would produce the same or improved results. 3. ROLES AND RESPONSIBILITIES A.

During emergencies, REU assumes the primary role and informs providers when there is damage or risk to their equipment. D. COORDINATION WITH CITY OF REDDING DEPARTMENTS Redding Fire Department The COR Fire Department is the lead agency in cooperation with. REU for implementation of the REU Wildfire Prevention and Improved Response Program. RFD, as the City's lead for emergency operations, directs REU regarding public safety priorities. Redding Police Department REU coordinates with RPD and is subordinate for emergency and public safety issues. REU will work closely with the RPD for situational awareness and other public safety issues related to this Plan. Redding Public Works Department REU is investigating opportunities to harden the electrical system and increase survivability for critical water and wastewater infrastructure. During wildfires and other public safety events, REU works with Public Works to ensure power to water -pumping stations, wastewater plants, and other critical infrastructure. These facilities are not only critical for defending the City from wildfire but are essential for safe repopulation following any disaster. Additionally, the Redding Area Bus Authority (RABA) is a critical operation for evacuations during emergencies and will be part of the infrastructure considered for reliability improvements. Redding Community Services Department REU is partnered with the COR Community Services Department as part of the REU Wildfire Prevention and Improved Response Program for fire fuels mitigation as well as other programs and projects. Other COR Departments and Administration REU, as a member of the City of Redding Team, will work to ensure information regarding warnings, alerts, and widespread outages is shared with other departments. The City Communications Team will be an integral part of getting information out to the media and public and will coordinate with either or both the City's EOC or REU's DOC as well as any Incident Command in place. E. CAL OES STANDARDIZED EMERGENCY MANAGEMENT SYSTEM As a utility department of the COR located in Shasta County, REU may participate in various emergency operation centers depending on the situation and lead agency. As a local governmental agency, COR has planning, communication, and coordination obligations pursuant to the California Office of Emergency Services' Standardized Emergency Management System ("SEMS") Regulations, adopted in accordance with Government Code section 8607. The SEMS 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 13 Regulations specify roles, responsibilities, and structures of communications at five different levels: field response, local government, operational area, regional, and state. The COR (via Redding Fire Department) maintains an All Hazards Emergency Operations Plan that includes REU. The COR works closely with Shasta County to coordinate emergency operations, including the Shasta County Sherriff s Office of Emergency Services (OES). The Shasta County Sheriffs Office of Emergency Services (OES) coordinates with Federal, State, and local agencies to prepare for, respond to, and recover from emergencies and natural disasters. • OES is responsible for maintaining and updating the County Emergency Operation Plan (EOP), which is an all -hazards plan for Shasta County. • OES also coordinates and maintains the county Emergency Operation Center (EOC). The EOC can be used during a major incident to carry out the principles of emergency preparedness and emergency management between multiple agencies. • The Office of Emergency Services provides technical advice to the Sheriff on local emergency declarations and his direct link to the California Governor's Office of Emergency Services during disasters or any other critical incidents. In the event of a major incident, OES can work with CAL OES to obtain a Presidential proclamation. • OES works closely with other local agencies, assisting them in preparing emergency plans and disaster training. OES also serves as a point of contact for local agencies with the California Governor's Office of Emergency Services. Pursuant to this structure, REU coordinates and communicates with the relevant local, state, and Federal agencies. This includes participating in City and County EOC exercises as well as providing annual safety meetings. Pursuant to the Emergency Operations Program, an REU EOC Liaison will participate in the City or County EOC using the standardized Incident Command System (ICS). 4. WILDFIRE RISK AND RISK DRIVERS A. BACKGROUND Within REU's service territory and the surrounding areas, the primary risk drivers associated with geography and climate for wildfire are the following: a) Extended drought b) Vegetation type C) Vegetation density (especially the West side and greenbelts) d) Weather e) High winds f) Terrain 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 14 g) Low humidity h) Changing weather patterns i) Communities at risk j) Fire history B. ENTERPRISE SAFETY AND WILDFIRE RISK METHODOLOGY To ascertain the level of risk to our system, REU assessed wildfire risk by looking at our historic outages caused by animals, birds, vegetation, car -pole accidents, and overhead equipment failures. Additionally, REU will review historical fire records to see if there are other areas of risk that should be addressed. REU has conducted multiple operational risk inventories to determine the appropriate methodology when assessing risk. The following criteria were identified when assessing risk: severity, probability of occurrence, mitigation to be done, and speed of onset. This includes identifying, analyzing, and prioritizing risks associated with catastrophic events, such as wildfires. Key REU assets can be found in the 10 -year Capital Improvement Program. SYSTEM AND OPERATIONAL RISK REU designs and constructs its electric facilities to meet or exceed the relevant federal, state, or industry standards. REU treats CPUC General Order (GO) 95 as a key industry standard for design and construction standards for overhead electrical facilities and, as such, closely follows applicable standards in GO 95. Additionally, REU monitors and follows the National Electric Safety Code as appropriate. Risk drivers associated with design, construction, operations, and maintenance within our 60 - square -mile service territory include approximately 50% of territory that is CPUC Tier 2 and 3 high fire threat areas; including 18,000 acres adjacent to REU equipment and facilities, and 120 miles of overhead power lines. C. GEOGRAPHICAL AND CLIMATE RISK Redding typically experiences cool, wet winters and hot, dry summers, creating extreme fire weather conditions, especially from May through September. Daily temperatures during fire seasons (June -October) are usually above 90° Fahrenheit with a relative humidity of less than 30%. Typical vegetation within wildland-urban interface areas includes blue oak, valley oak, gray pine, and annual grasses. Areas of dense brush and annual grasses are common and result in high fire danger and significant fires, especially during north wind events. These conditions combine to create extreme fire danger, with the city facing one of the highest wildfire threats in the state. The risk of catastrophic wildfire in the area rises as the recent trend of drought conditions increases. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 15 Table 3: Attributes of Redding Electric Utility ' This data shall be based on the definitions and maps maintained by the United States Department of Agriculture, as most recently assembled in The 2010 Wildland-Urban Interface of the Conterminous United States. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 16 Service Territory Size 61 square miles Owned Assets X Transmission X Distribution X Generation Number of Customers 46,758 customer accounts Served Population Within Service 92,465 people Territory Number of Accounts Share of Total Load {MWI 52 % Residential; 86 % Residential; Customer Class Makeup 2 % Government; 8.4 % Government; - % Agricultural; - % Agricultural; - % Small/Medium Business; - % Small/Medium Business; 12 % Commercial/Industrial 39.6 % Commercial/Industrial - % Agriculture 9.43 % Barren/Other - % Conifer Forest - % Conifer Woodland Service Territory - % Desert Location/Topography - /o Hardwood Forest - % Hardwood Woodland - % Herbaceous - % Shrub 75.4% Urban 2.6% Water Service Territory 38% Wildland Urban Interface; Wildland Urban Interface' 24% Wildland Urban Intermix (based on total area) Percent of Service Territory Tier 2: 33.5% in CPUC High Fire Threat Tier 3: 12.5% Districts (based on total The CPUC High Fire Threat Map is included in Appendix A of REU's area) Wildfire Mitigation Plan.

The Carr Fire of July 2018 resulted in the deaths of eight people and destroyed over 2,000 structures in Shasta County, including 270 homes within Redding. Redding Electric Utility recognizes the impacts to our forestry and the increased wildfires due to climate change throughout California and the Northwest. As such, REU reviews the data portraying climate change in California and specifically in Redding through the Cal-Adapt.org collaboration of state funding programs along with university and private peer-reviewed researchers. REU understands that temperatures are projected to rise in California during the 21St century, which will potentially increase fire seasons due to the extended extreme heat. One of our key programs within the WMP is our Wildfire Prevention and Response, which takes into consideration these external climate factors. By partnering with key stakeholders within the City of Redding, such as the Parks, and Fire Department, we are focusing on reducing vegetation near distribution lines and substations, as well as decreasing response time by first responders for fires caused by or near REU infrastructure. D. CPUC HIGH FIRE THREAT DISTRICTS REU directly participated in the development of the California Public Utilities Commission' s (CPUC) Fire -Threat Map, which designates a High -Fire Threat District. REU will incorporate the High Fire Threat District into its construction, inspection, maintenance, repair, and clearance practices, where applicable. REU reviews CPUC Fire Threat Map annually to identify needed adjustments to hazard threat levels due to changes in urban development and/or vegetation conditions. When adjustments are identified, REU collaborates with Redding Fire Department and CAL FIRE to update the CPUC Fire Threat Map data and REU's Fire Threat Map accordingly. There have not been any additional recommended areas to be added to the Tier 2 or 3 areas since December 2020. I, W lY7r11xllt`diIPC"SIIrrrU130 4INIMIX JOldIW01I REU meets or exceeds the minimum industry standard vegetation management practices for transmission -level facilities. For both transmission and distribution level facilities, REU meets: (1) Public Resources Code section 4292; (2) Public Resources Code section 4293; (3) GO 95 Rule 35; and (4) the GO 95 Appendix E Guidelines to Rule 35. These standards require significantly increased clearances in the High Fire Threat District. The recommended time -of -trim guidelines do not establish a mandatory standard, but instead provide useful guidance to utilities. REU will use specific knowledge of growing conditions and tree species to determine the appropriate time of trim clearance in each circumstance. REU treats both native and non-native trees in our service area. The following trees are vigorous in growth and are treated regularly: oak, ailanthus altissima, 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 18 and poison oak. REU performs this work with nine arborists supplemented with contracted inspectors and Line Clearance Arborists. The radial clearances shown below are recommended minimum clearances that should be established, at the time of trimming, between the vegetation and the energized conductors and associated live parts where practicable. Reasonable vegetation management practices may make it advantageous for the purposes of public safety or service reliability to obtain greater clearances than those listed below to ensure compliance until the next scheduled maintenance. Each utility may determine and apply additional appropriate clearances beyond clearances listed below, which take into consideration various factors, including line operating voltage, length of span, line sag, planned maintenance cycles, location of vegetation within the span, species type, experience with particular species, vegetation growth rate and characteristics, vegetation management standards and best practices, local climate, elevation, fire risk, and vegetation trimming requirements that are applicable to State Responsibility Area lands pursuant to Public Resource Code Sections 4102 and 4293.

Additionally, the Parks staff conducts weed abatement around power poles in high threat areas. Power poles in high-risk areas were treated with fire retardant material during the 2021 fire season. New technology was developed and REU started wrapping power poles in high-risk areas with a fire -retardant webbing, allowing for longer protection of the poles. Over 500 poles were wrapped in 2022 and 230 power poles were wrapped during calendar year 2023. As of the end of 2024 861 poles have been wrapped with fire retardant wire mesh. An additional 700 poles have been targeted within high-risk areas for pole wrapping starting in 2025. REU utilizes goats in areas near power lines that are often difficult for personnel to reach. REU works directly with private property owners on vegetation management in high fire threat zones to lower fire risks. For a comprehensive list of prevention efforts conducted during the 2024 calendar year see Appendix G-2024 Wildfire Mitigation Plan Monitoring and Auditing Report. The City of Redding Parks Department and REU Arborists perform the work listed below annually prior to the north state fire season each year. In addition to adopting the REU Wildfire Mitigation and Improved Response Program described below, enhancements to our traditional vegetation management described above include: • No vertical coverage allowed above REU I I5kV transmission lines; • Provide vegetation control in a 30 -foot perimeter around the Power Plant and substations as property lines and easements allow. All vegetation within the designated perimeter have been removed within four inches of earth and vegetation maintenance is performed annually at each location. • Public land and greenbelts throughout the City of Redding are located in all three Tier levels and REU clears required poles from ground to sky adjacent to REU facilities. • REU prioritizes vegetation management around all utility infrastructure in these areas. In conjunction with various City Departments, REU focuses on mitigating potential fire threats associated with illegal outdoor camps in greenbelt areas. • Customers not allowing clearing (refusing treatment) are documented. Their refusal information becomes part of the customer's file in the GIS information system database. • Work with adjacent customers to get approval for wider clearance on their land. This could include tall, diseased, leaning trees that appear to be at risk of falling into our lines. Coordinate with police and fire if necessary clearing is refused (forced trim); • Perform additional vegetation removal for fuels reduction in the easement on an annual rotation to ensure CPUC recommended clearances are maintained based on the fire hazard zone where each transmission and distribution line is located. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 20 B. STRATEGY - ENHANCED INSPECTIONS Inspection plays an important role in wildfire prevention. REU patrols its system regularly and has taken steps to optimize its inspections. REU's current inspection activities include several components in accordance with GO -95, 128, and 165, which include annual patrols, detailed inspections, and intrusive inspections of wood poles. Furthermore, REU utilizes contracted arborists to conduct line clearance inspections of the entire transmission and distribution system annually. For a comprehensive list of enhanced inspection efforts conducted during the 2024 calendar year see Appendix G -2024 Wildfire Mitigation Plan Monitoring and Auditing Report. C. STRATEGY - SITUATIONAL AWARENESS REU installed an automated outage management system that has the ability to track customers affected by circuit outages (not individual customers until Automated Meter Infrastructure is approved in the future) and provide customer notification through outage mapping and interactive voice response (IVR). Other efforts include the following technology in collaboration with RFD, RPD, and the City's Information Technology (IT) Department: • Utilize strategically located surveillance cameras for early detection of fires or suspicious activity; This is also part of REU's SB699 Physical Security Plan; • Expanded use of Automatic Vehicle Locators (AVL) for response and recovery for REU, RFD, and RPD; • Implemented a common Motorola radio communication system for REU, RFD, and RPD for wildfire and disaster response and recovery; • Provided human resources for implementation, operation, and maintenance of technologies: Customer reporting tools for safety issues; • Completed a state-of-the-art Department Operations Center to integrate and disseminate situational data. Other enhancement to public notification during high fire threat, actual fire, or other disaster events can be found in Appendix G-2024 Wildfire Mitigation Plan Monitoring and Auditing Report. D. STRATEGY - OPERATIONAL PRACTICES REU will operate the system in a manner that will minimize potential wildfire risks, including taking all reasonable and practicable actions to minimize the risk of a catastrophic wildfire caused by REU electric facilities. REU will take corrective action for deficiencies when the staff discovers or is notified of improperly installed or maintained fire protection measures. In addition to those 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 21 general principles, several new operational practices will help reduce the risk of wildfire and improve the response time in the event of a fire, including: • During high wildfire threat periods (red flag warnings) perform work as described in SOP - 35. All personnel in contact with RFD and RPD reporting anything hazardous. REU Emergency Operations Program (EOP) on Level 1 status; • REU performs bi-annual system drills for the REU EOP in conjunction with summer and winter preparation meetings. Summer drills are performed no later than May 31 of each year; winter drills are performed no later than December 15 of each year. If an actual alert level is experienced due to a Red Flag warning or other activity, the drill may not be necessary; • Collect and maintain wildfire data necessary for the implementation and evaluation of this Wildfire Mitigation Plan. E. STRATEGY - SYSTEM HARDENING REU's electric facilities are designed, constructed, and maintained to meet or exceed the relevant federal, state, or industry standard. REU treats CPUC General Order (GO) 95 as a key industry standard for design and construction standards for overhead electrical facilities. REU meets or exceeds all standards in GO 95. Additionally, REU monitors and follows as appropriate the National Electric Safety Code. In addition to standards, REU will consider some or all of the following as described in the 10 -year Capital Improvement Program: • Non-exempt poles with operating devices are cleared of all vegetation around them with a minimum radius of 10'. Perform this for every applicable wood pole in the system for resiliency; • Provide additional access roads along power line easements and maintain to appropriate standards; • Critical power poles located within high-risk areas are wrapped with fire retardant material for added protection; • Increase stock of air filters for power plant before each summer; • Engineering — Revise construction standards to implement arc suppression components, raptor framing, squirrel guards, tree wire, lightning arrestors, and arc suppression fusing. • Convert overhead lines to underground as feasible and economical; Install covered conductor and tree wire. • Alternative Technologies- REU will consider the feasibility of implementing alternative technologies, such as wire -break sensing and arc detection technology, as they become available and cost-effective. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 22 For a comprehensive list of system hardening projects conducted by REU in 2024, see Appendix G-2024 Wildfire Mitigation Plan Monitoring and Auditing Report. F. STRATEGY - PUBLIC SAFETY AND NOTIFICATION The following is part of this Plan to communicate with the community during high -fire threat periods and disasters. • Coordinate with Redding Fire Department (RFD) and Redding Police Department (RPD) through REU's 24/7 Power Control Center (PCC); • Coordinate with RFD and RPD through the REU EOP during emergencies or large-scale outages; • Coordinate with RFD and RPD in conjunction with the joint dispatch agency, Shasta Area Communication Agency (SHASCOM), for notification to areas that require power shutoffs as directed by public safety during emergencies; • Developed communications protocol with Shasta County Health and Human Services for notifications to vulnerable groups; • REU utilizes social media such as Facebook, Twitter, and Instagram along with the COR Communications Team to proactively communicate with the customers in the City of Redding during Red Flag Warnings, fires, and other utility -related emergencies; • A publicly facing map provides information for the public to view current outages and estimated restoration times; • Use public service messages on local radio and television media related to wildfire safety. G. STRATEGY — RECLOSING, DE-ENERGIZATION REU disables automatic reclosing on circuits that traverse Tier 2 and enables high-speed tripping for Tier 3 areas during periods in which the National Weather Service (NWS) and National Oceanic and Atmospheric Administration (NOAA) issues a Red Flag Warning or at REU Management discretion for safety purposes. REU will continue to shut off power when requested by Redding Fire, Police, Cal Fire, or other emergency responding agencies. In addition to temporary shutoff requests from the above entities, the use of a Public Safety Power Shutoff (PSPS) may be utilized to prevent igniting a fire during extreme fire weather events and other events with additional high -fire threat conditions. The Reclosing and De-Energization program is documented in SOP -35. REU will limit preemptively shutting off power (PSPS) during high fire threat periods for the following reasons: • Our service territory is only 60 square miles and relatively compact and visible with proper technology; 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 23 • Approximately fifty percent (50%) of the City's eight hundred (800) miles of distribution lines are located below ground; • The City has eight (8) Redding Fire Stations positioned strategically throughout the City and with the additional fifteen (15) Firefighters hired through the Wildfire Mitigation Plan, the response time by fire personnel, should a fire occur, will be reduced significantly; • All identified law enforcement, fire, and hospital facilities are within the Non -High Fire Threat Zone boundaries; • Five (5) of the REU substations are located within the Tier 2/3 boundaries; • CalFire Northern Operations Division and CalFire Shasta Trinity Unit headquarters are located within the City of Redding limits along with CalFire's Air Attack Unit, and multiple CalFire Substations are located in and around the City limits, ensuring timely mutual aid response; • The City hired fifteen (15) Firefighters, and eight (8) Public Works Maintenance employees and is proactively mitigating Tier 2 and Tier 3 fire zone areas by removing brush and trees near Redding Electric equipment and lines; • Turning off the power could put the community at higher risk of wildfire as it could impact water pumping and also create abnormal human activity that could increase the opportunity for fire. REU will respond to direct requests to de -energize from the Redding Fire Department; • REU is investing in our Wildfire Mitigation and Improved Response Program as one way to mitigate power shut -offs; • REU plans to have real-time information from staff located in areas identified as at risk of being subject to extreme weather conditions; • REU makes use of social media and the REU website to communicate relevant and timely notifications, as well as a public outage portal map. • REU plans to use system hardening, situational awareness, vegetation management, and other strategies to avoid shutting off power. • As part of this Wildfire Mitigation Plan, REU may disable automatic reclosing, enable fast -trip protection, or both, on circuits that traverse tier 2 or 3 areas or are considered a fire risk during periods in which the National Weather Service issues a Red Flag Warning or at REU Management discretion for safety purposes. H. STRATEGY - WILDFIRE RESPONSE AND RECOVERY • During a high fire threat event (specifically Red Flag Warning periods issued by the National Weather Service), RFD will attempt to up staff and stage fire protection equipment in a ready status and the REU EOP will go to a Level 1 (SOP -35); • First Responders shall provide access to the Redding Power Plant staff for necessary shift changes during fire events; • Wildfire Response: Execute the REU Emergency Operations Program (SOP -200); • Recovery/re-energization will follow priorities set by SOP -28, System Restoration. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 24 • REU is a member of the California Utility Emergency Association, which plays a key role in ensuring communications between utilities during emergencies including mutual aid. REU also participates in the Western Energy Institute's Western Region Mutual Assistance Agreement, which is a mutual assistance agreement covering utilities across a number of western states. 1. PROGRAM — REU WILDFIRE PREVENTION AND IMPROVE RESPONSE On May 7, 2019, the Council approved the REU Wildfire Prevention and Improved Response Program (Appendix B). The Program provides funding to the Redding Fire Department and the Community Services Department for services rendered to prevent the start of wildfires through fire fuels reduction as well as provide faster response in the event of a wildfire either caused by or threatening the electric utility assets located in and around the City of Redding. The Redding Fire Department provides coordination between REU and other local fire agencies as well as oversight of the Program. Specifically, this program provides fifteen Firefighters to increase staffing from two -person to three-person crews. This improves initial fire response. Finally, eight Public Works vegetation crew workers perform fire fuels mitigation. In total twenty-three personnel continue to augment REU's existing nine arborists. Additional outside arborist crews and vendors will continue to be utilized as needed to reduce vegetation and high-risk fire areas. J. PROGRAM — REU TECHNOLOGY SOLUTIONS Through the application of technology, REU will be able to more effectively protect and reduce threats to the electric utility infrastructure and the customers who rely upon it. The following technologies will greatly enhance REU's ability to minimize sources of ignition, manage vegetation within the City's electric grid, enhance the productivity of utility staff, harden systems, more effectively protect and notify the public if an issue arises, as well as shorten the response and recovery time in the event REU equipment contributes to starting a wildfire. Technology also helps to heighten situational awareness and enhances public safety response time, allowing first responders to react in an appropriate and effective manner before, during, and after a wildfire. The Program provides funding to the Redding Police Department (RPD) and the City Information Technology (IT) Department for services rendered to help prevent REU caused wildfires. video monitoring of facilities, a common communication platform, and a GPS -based vehicle tracking platform. The memorandums of understanding (MOUS) are attached in. Appendix E. Specifically, this program provides a common radio platform, including base stations, handhelds, and vehicle -mounted radios for REU personnel, as well as radio equipment for Redding Police personnel, Redding Fire personnel, and Automatic Vehicle Location (AVL) tracking devices on 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 25 all Electric Utility vehicles and necessary upgrades for first responder vehicles. The common communication and GPS vehicle tracking platforms will be expandable and be designed to allow easy adoption by other City Departments at a small incremental cost. The Program also funds the Department Operations Center, where all of the technology is integrated, which enhances situational awareness during high fire threat days, system outages, and emergencies. K. PROGRAM — REU DISTRIBUTION 10 -YEAR CAPITAL The objective of the 10 -Year Capital Improvement Program (Appendix D) is to enhance the distribution system to replace specific components used on the electrical distribution system to reduce the probability that the system itself will initiate a fire as well as harden the electrical distribution system to better survive a fire initiated by other sources. The specific program objectives are being designed and were completed mid -2021. These objectives will be achieved using the following five strategies: • Enhanced inspections and tracking of assets; • System hardening of key subsystems; • Improved situational awareness; • System improvements providing better operational practices; • The addition of switching to provide precision de-energization. L. PROGRAM — REU EMERGENCY OPERATIONS The Redding Electric Utility Emergency Operations Program (REU-EOP) (Appendix C) is an all - hazards EOP that uses a system operating procedure format to ensure compatibility with current practices as well as a utility -wide application. The REU-EOP was designed using the same format as the City of Redding Emergency Operations Plan (City EOP) and includes the use of the Incident Command System (ICS). The main REU-EOP elements include Standard Operating Procedure (SOP) 200, an Incident Communication Guide, and Emergency Operations Contact Information. Upon review of the City's EOP (adopted in 2014), the utility is responsible for several restoration and incident management objectives during an emergency. The REU-EOP recognizes this responsibility and connects the existing City-wide emergency operations responsibilities to the responsibilities dictated by the REU-EOP in order to support an efficient and effective emergency response to any hazard. REU maintains multiple electric system operating procedures designed to mitigate, communicate, and restore abnormal system conditions to normal status. As evident from the 2018 Carr Fire and the February 2019 snowstorm event, the utility could greatly benefit from the implementation of a utility -wide EOP that utilizes the Incident Command System (ICS) structure along with the established electric system operating procedures. Fortunately, REU is organizationally structured to easily fit into the ICS unit system with appropriate roles and responsibilities between incident 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 26 command (Executive Team) and section chiefs (Leadership Team). Therefore, the implementation of SOP -200 fits well within the roles and responsibilities segmented appropriately. As required, the REU-EOP establishes a Department Operations Center (DOC) at the REU Headquarters Building at Avtech Parkway during emergency conditions. This DOC will work in collaboration with the PCC (Redding Power Plant) where both facilities will have video conferencing capability to ensure ease of communication during events. Having the DOC remote from the PCC will allow it to be used as an EOC for the City. The Incident Communication Guide was drafted to support the REU Public Information Officer (PIO) and staff with both internal and external communications during an emergency. As required in the City's EOP, an Emergency Operations Contact Information document has been created with a Listing of key REU emergency response personnel, a conference bridge, and emergency contact email and phone information. The REU-EOP has been transferred to Utility Operations as of August 31, 2019 for ongoing administration, training, and upkeep. REU will maintain a proactive outreach and education strategy to create public awareness of fire threats, fire prevention, and available support during a wildfire or large power outage. Prior to an emergency, communication will include regular messages related to wildfire prevention, such as right-of-way management, tree trimming, line inspection, or other relevant topics. Methods of communication will include newsletters, website updates (including City Hub), social media posts, and public service announcements. During an emergency, the REU Emergency Operations Program includes an REU Incident Communication Guide that will be utilized to manage both internal and external communication throughout the incident from that initial notification to termination of the incident. Use of these established notification and communication plans will allow REU to coordinate with applicable emergency service personnel (Redding Fire Dept., Cal Fire, Cal OES, Redding Police Dept., etc.) along with maintaining open lines of communication with customers, media, and internal City staff. Communications will be coordinated as appropriate with the City Communications Team. 7. RESTORATION OF SERVICE In the event of a wildfire or other emergency event, REU will staff up its DOC to coordinate activities to restore service. REU will restore power following an event in cooperation with the City of Redding Fire, Police, and Public Works Departments and in coordination with Cal Fire, Shasta County, or another named Incident Commander. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 27 REU management will oversee restoration and response activities. In the event that additional staff is needed, REU may leverage mutual aid agencies, other City of Redding staff, and local aid organizations. The utility may also engage contractors on an as -needed basis. The following describes the steps typically taken to begin the restoration process: Declaration of Emergency. The City of Redding may declare an emergency depending on the scope of the disaster. Assessment. REU crews must patrol each line segment to determine the extent of damage that has occurred. The patrol involves assessing equipment access issues, any cleanup/debris removal. issues and determining personal protective equipment requirements for the crews. REU works with the local agency in charge of the fire to access impacted areas as soon as the area is deemed safe by fire officials. Planning. After initial assessment, REU supervisors, managers and engineers meet to plan the needed work. The team will work with system operations to prioritize the restoration efforts, targeting the circuits that serve the most critical infrastructure needs. Mobilize. Based on the size and complexity of the rebuild/restoration efforts, REU will coordinate the crews and material needs internally if possible. Mutual aid and contractors may be used on an "as needed" basis to provide additional support. REU maintains a critical material vendor list and has contracts it can draw on for labor and material needs. In an instance of widespread catastrophic damage, necessary materials and labor could experience shortages that may delay work. Rebuild. The rebuild effort lead by REU will commence as soon as areas become safe and accessible. The initial efforts will be to get the lines up and restore the damaged circuits. Depending on the extent of damage, demolition may be performed concurrently or after crews start installing new facilities. REU will incorporate new materials and technologies as indicated and available. Restore. REU, mutual aid, or contract crews will restore electric services to homes and businesses as soon as possible after the wildfire. Depending on the extent of damages, residential and business customers may have to perform repairs on their facilities and pass inspections by local agencies prior to having full electric service restored. In most cases, the following restoration priorities will be followed depending on the specific incident and available resources: • Public safety in the affected areas; • Worker safety in performing the restoration work; • Life-support or critical customers; • Critical infrastructure (Key City and County facilities and accounts; Sheriff's Department and jail, City Police and Fire Departments, other key utility facilities (e.g., water, sewage, 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 gas, citywide communications), Incident Command Site or Base Camp, Incident Evacuation Centers, local broadcast and radio Stations, etc.); • Major commercial activities/accounts critical to continuity of community services (e.g., gas stations, food stores, home supply stores, repair shops, eateries and lodging facilities, financial institutions, etc); • To reduce the total number of customers affected; • To reduce the length of time customers have been without power. In directing restoration efforts to best achieve the above priorities, REU Operations Group personnel will generally find it most efficient to dedicate restoration resources to the following types of facilities in the following order of priority to optimally restore electric services: • Redding Power Plant facilities (RPP); • Other energy supply resources (to ensure power can be delivered/received via Western Area Power Administration, the COTP, from within BANC, the CAISO, etc.); • Transmission circuits (115 kV) subject to NERC requirements; • Substations; • Distribution circuits (12 kV); • Distribution feeders; • Distribution transformers; • Service lines. 8. EVALUATION OF THE PLAN MOO] M'111111111 I I' REU tracks two metrics to measure the performance of this Wildfire Mitigation Plan: (1) number of fire ignitions caused by REU facilities or operations; and (2) wires down within the service territory. Metric l: Fire Ignitions For purposes of this metric, a fire ignition is defined as follows: • REU facility was associated with the fire; • The fire was self -propagating and of a material other than electrical and/or communication facilities; • The resulting fire traveled greater than one linear meter from the ignition point; and • REU has knowledge that the fire occurred. For information related to the number of fires caused by REU facilities see Appendix G-WMP Annual Monitoring and Auditing Report. Metric 2: Wires Down 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 29 The second metric is the number of distribution and transmission wires downed within REU's service territory. For purposes of this metric, a wire down event includes any instance where an electric transmission or primary distribution conductor falls to the ground or onto a foreign object. REU divides the wires down metric between wires down inside and outside of the High Fire Threat District. REU does not normalize this metric by excluding unusual events, such as severe storms. Instead, REU supplements this metric with a qualitative description of any such unusual events (including car vs. pole incidents). B. IMPACT OF METRICS ON PLAN Appendix G — Wildfire Monitoring and Auditing Report provides the impact on the metrics of the plan. REU will continue to identify areas of its operations and service territory that are disproportionately impacted and evaluate potential improvements to the plan. REU staff will continue to collected data update the WMP annually. Notable changes include the implementation of a workforce management program, contracting with vendors for vegetation and equipment inspection, and upgrades to the internal inspection process improving the overall auditing and reporting of utility caused fires. REU has improved the collection process along with monitoring and reporting of events. Review of this Plan will occur annually and any lessons learned will have the highest priority for improving steps in the plan, any reference programs, and the process for implementation. REU will present this plan to the Redding City Council on an annual basis at a regularly scheduled City of Redding Council Meeting on the Regular Calendar allowing public comment on the elements of the plan. D. IDENTIFYING AND CORRECTING DEFICIENCIES IN THE PLAN REU staff and qualified external stakeholders are encouraged to identify Wildfire Mitigation Plan deficiencies or potential deficiencies to the Assistant Director of Utility Operations as soon as possible when observed. The Assistant Director of Utility Operations shall evaluate each reported deficiency and if the deficiency is determined to be a valid plan deficiency, it shall be entered into a log with the following information: • Date the deficiency was discovered; • Description of the deficiency; • Source identifying the deficiency (e.g., Internal Audit); • Priority based on deficiency severity; • Assigned corrective action, including the date when it must be completed by; • Assigned staff responsible for completing the corrective action; 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 30 • Date corrective action completed. The Assistant Director of Utility Operations will go over the log at regularly scheduled Leadership and Supervisor Meetings. E. MONITORING THE EFFECTIVENESS OF INSPECTIONS REU will perform inspections on either a 5 -year, 1.5 year, or annual cycle, based on GO 165 or fire mitigation recommendations. Any areas or equipment found that need improvement or appear hazardous will be documented with a work order, given a priority, and the work order will be tracked. When completed the work order will have a close date. The Assistant Director of Transmission and Distribution Assets will assign qualified internal staff or engage a third parry to review and audit the equipment and line inspection programs called out in the Wildfire Mitigation Plan after the completion of the first six months of the plan. The assigned auditor will: • Review records for the inspection programs; • Interview staff performing inspections to assess their knowledge of the inspection programs; • Monitor staff performing inspection activities; • Review deficiencies noted in the programs; • Identify systemic issues or problems; • Note the timeliness of corrective actions; and • Pick a random sample of some completed corrective actions and verify the effectiveness of the corrective actions; and • Issue a written report of findings. The Assistant Director of Transmission and Distribution Assets will review the audit findings and assign corrective action as applicable. A copy of the audit report will be routed to the Director. `'TAIN7I11:7 11/11 gcm, 9U930■9KRO ER*09111[1301 A.

These objectives will be achieved using the following five strategies: Enhanced inspections and tracking of assets; System hardening of key subsystems; Improved situational awareness; System improvements providing better operational practices; The addition of switching to provide precision de-energization. System Improvements Description The suggested system improvements are proposed to be as described below: 1) Field Verify / T2 / T3 Boundary: The present CPUC maps defining the Tier 1, 2, and 3 boundaries were created as statewide maps that lack the detail necessary to accurately define the operation of the utility assets within the City of Redding (COR). An assessment will be performed to provide clarity of what the actual fire hazards are at critical locations on the REU distribution system. Mitigation shall be performed for certain circuits to allow the recloser operation to be reinstated and removed from the list shown in Attachment 2. 2) Perform necessary tree trimming and removal in priority areas. 3) Reconfigure specific Circuits to feed only Tier 1. 4) Install non -arcing arrestors, fuses, and squirrel guards and add covered wire jumpers. 5) Create 30 -foot sterilized perimeter for T2 and T3 substations. 6) Apply fire retardant to poles for T2 and T3. 7) Install fault indicators in order to locate issues faster. 8) Install Mesh Network to retrieve fault and outage data. 9) Connect Line Fault Indicator data to SCADA. 10) Provide secondary water source to Power Plant. 11) Install additional 12KV switches at T I boundary. 12) Install fast reclosers/sectionalizers at T I boundary. 13) Convert overhead to underground for critical COR water plants. 14) Improve existing and add additional access roads to critical sections of the distribution system. 15) Replace existing I I 5KV poles with steel pole in T2 and T3 areas. 16) Convert overhead to underground where it is deemed cost effective. 17) Convert Keswick River Crossing from wood to steel. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 42 System Improvements Timeline Priority will be given to the improvements that can be deployed the earliest, with the largest estimated return in meeting the Program objectives. Improvements which require larger efforts such as city-wide studies and design consultant efforts will be implemented as they are completed. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 EK AlIvild W10m SOLUTION -- PROGRAM�l 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 E Overview Through the application of technology, REU will be able to more effectively protect and reduce threats to the electric utility infrastructure and the customers who rely upon it. The following technologies will greatly enhance REU's ability to minimize sources of ignition, manage vegetation within the City's electric grid, enhance productivity of utility staff, harden systems, more effectively protect and notify the public if an issue arises, as well as shorten the response and recovery time in the event REU equipment contributes to starting a wildfire. Technology also helps to heighten situational awareness and enhances public safety response time, allowing first responders to react in an appropriate and effective manner before, during and after a wildfire. The Program provides funding to the Redding Police Department (RPD) and the City Information Technology (IT) Department for services rendered to help prevent REU caused wildfires and protect REU facilities from the threat of wildfires through aerial surveys of REU's overhead electric lines, video monitoring of facilities, a common communication platform, and a GPS based vehicle tracking platform. The memorandums of understanding (MOUs) are attached. Specifically, this program provides for an estimated total of forty (40) cameras; a common radio platform, including base stations, handhelds and vehicle mounted radios for REU personnel as well as radio equipment for Redding Police and Fire command Staff; and Automatic Vehicle Location (AVL) tracking devices on all Electric Utility vehicles and necessary upgrades for first responder vehicles. The common communication and GPS vehicle tracking platforms will be expandable and be designed to allow easy adoption by other City Departments at a small incremental cost. Cameras for Utility Operations, Fire Detection and Mitigation Situational awareness is instrumental in combating fires in and around our community. Camera technology is a vital element in the early detection and intrusion of wildland fires into the City of Redding. In addition, cameras provide critical information related to any REU equipment that may be a contributory cause to a fire. The installation of cameras in areas surrounding REU's critical infrastructure will greatly enhance first responder's ability to identify, locate, and mitigate fire threats. Live feed cameras mounted throughout REU's service territory will assist with the early detection of fires caused by the electric system. Strategically placed cameras in the proximity of REU's transmission lines, especially in the Tier 2 and Tier 3 fire areas, will also aid in risk assessments during designated Red Flag warning days or a fire weather event in which an Emergency Operations Center is activated. Early assessment and detection allows REU to quickly react and prevent the system from inflicting harm on the surrounding areas. Mobile cameras will also be used in a variety of preventative ways through the use of Unmanned Aerial Vehicles (UAVs). This includes the identification of potential right-of-way hazards as well 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 45 as the location and isolation of hot spots in REU distribution lines using Forward Looking Infrared Radar (FLIR) technologies. In the event a fire is seen or reported, fixed cameras and UAVs can quickly discover and identify hot spots in the area, help determine the potential for the fire to spread, and give first responders specific intelligence related to scaling fire resources up or down appropriately. In addition, strategically placed fixed cameras assist first responders in determining the best evacuation routes through enhanced situational awareness. Fixed and UAV cameras allow firefighters and first responders to more effectively manage firefighting operations. Speakers mounted on UAVs greatly enhance the ability to communicate with first responders in the danger area and with citizen evacuations. HD video streaming from the UAVs to the Department Operation Center (DOC) or command staff on computers/cell phones will allow those in control of fire operations to see a live, real- time video feed of the fire. This will streamline firefighting capabilities and enable command center personnel to make quick decisions based on real-time information, rather than using information that has been relayed through multiple parties or having to wait until first responders are in place. Command center personnel will be able to see the direction a fire is spreading, providing the ability to move resources to the most effective positions. Implementation of an artificial intelligence overwatch camera and software system will assist in the early detection of fires. Fire watch systems are specifically manufactured for early wildfire detection and can be calibrated for any region, vegetation, and type of weather. This technology includes a triple optical sensing unit, control and detection software that performs self- diagnostics, and smoke detection. While this technology is recommended to be used with a detection radius of ten (10) miles, it has proven itself capable of locating smoke plumes up to forty (40) miles away during clear weather days. When smoke is detected by the system it alerts users so that first responders can react quickly and efficiently before flames reach the tree tops. Early detection of fire arising proximate to REU facilities using the system allows first responders to launch a direct attack using minimal resources and results in both physical and monetary savings to REU. Fire caused by REU facilities or threatening REU facilities can rapidly becoming a city-wide threat to the inhabitants of the City. City-wide issues and concern can begin long before the cause of a fire is known due to lack of certainty. By determining the cause, or origin, of a fire quickly, we can not only save life and properties, we can mitigate the risk of uncertainty. In this regard, early detection of fire caused by REU facilities or threatening REU facilities protects the City as a whole. Aerial Ima2ery The city-wide aerial orthophotography is a core data set for the GIS Division. Aerial imagery or orthophotography provides the picture from which many GIS data layers are created and maintained. For example, our parcels, roads, water system, wastewater system, and storm drain system GIS layers are all created and maintained using high-resolution orthophotography. Also, high-resolution imagery is a powerful visual tool when represented on maps and exhibits. It is 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 46 important that the imagery be kept up-to-date. The most recent aerial imagery was flown prior to the Carr fire, and is therefore not a true representation of our community's current landscape. New imagery would allow fire crews to be able to identify current overgrown areas proximate to REU facilities, as well as those areas at a higher risk of fires. Ensuring the imagery is kept up to date on a more frequent basis will play a critical role in ensuring fire crews are able to maintain a clearer/safer landscape around REU facilities as vegetation regrows. Newer imagery would allow for accurate GIS data, which in turn, would further enhance the City's Fire Department in their fire mitigation efforts to enhance wildfire buffers around REU facilities. This imagery will be performed every two years. City -Wide Communications Platform Immediate and reliable communication is vital during an emergency such as a wildfire, or major storm event. The current City of Redding radio systems have reached their end of useful life and are requiring replacement. RPD is currently in the process of upgrading their existing radio system and REU is proposing to expand upon this project to include additional features that will meet Redding Electric Utility's need to monitor and react to wildfire threat to REU facilities or to protect the City from wildfire threat posed by REU facilities while also creating a unified platform across City Departments. By implementing a unified stationary and mobile communication platform, City of Redding personnel will have the ability to communicate across Departments during emergency situations quickly and efficiently. This platform will provide immediate connection to all parties, free of cross-channel interference, allowing each Department to work simultaneously and in support of one another. In addition to purchasing the communications platform, REU will provide radios for Electric Utility employees and Redding Police and Fire command staff to ensure reliable communication between first responders and REU to ensure the preservation of life and property. *Initial costs associated with the communications platform will be paid by REU. The Redding Police Department will be responsible for a partial repayment for handheld and vehicle radios through an interdepartmental lease process. This radio system will allow first responders to immediately report downed electric lines to REU or report a fire that has been started due to a downed line. This will lead to faster response times and better fire management. Direct radio communication between Redding Fire Department personnel to Police personnel will provide safe direction to high risk areas during evacuations as well as allow first responders to request specific power shutoffs from REU's DOC during an emergency. Automatic Vehicle Location (AVL) AVL will assist each Department with the identification and tracking of first responder and emergency vehicles. During a wildfire event, it is critical for the Department Operations Center (DOC) to be able to determine the location of each vehicle so that resources can be dispatched and/or redirected to REU facilities in the most effective manner, and to identify where a vehicle is located so assistance may be provided if an employee is in danger. AVL aids in the identification 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 47 of employee location during emergencies and allows dispatchers to warn personnel who are in the vicinity of an at -risk area. AVL will allow REU to track the progress of employees while patrolling equipment during a Red Flag outage. By doing so, REU can ensure that outages are handled quickly and efficiently, and that employees are not at risk. If an emergency situation is identified, AVL will provide REU with the ability to quickly report a vehicle's location and allow dispatchers to send first responders directly to the vehicle and employee(s).

Scope In conjunction with California Senate Bill (SB) 901, the City Council approved the Redding Electric Utility (REU) Wildfire Mitigation Plan (Plan) on December 3, 2019. The goals and objectives of the Plan included close monitoring and internal audits to reduce potential wildfire risks caused by or encroaching on Redding's electric equipment and infrastructure. These goals directly relate to REU's overarching objective of providing safe, reliable, and economical electric service to the Redding community. The Wildfire Mitigation Plan states, "Review of this Plan will occur annually, and any lessons learned will have the highest priority for improving steps in the plan, any reference programs, and the process for implementation." Subject Matter experts within REU are responsible for the monitoring and auditing, which consists of reviewing key elements within the Plan to document progress, identify deficiencies, improve both internal and external communications, and ensure REU continues to operate its electrical lines and equipment in a manner that minimizes the risk of catastrophic wildfire posed by its infrastructure. 11. Key Contributors Implementing the Wildfire Mitigation Plan is a collaborative effort with numerous City of Redding Departments working together in prevention and response, technology solutions, emergency operations, and the 10 -year capital improvement plan. Information and data have been tracked throughout the 2022 calendar year to measure performance and deficiencies, and to make improvements to the Plan for upcoming years. Key City of Redding partners in the Plan include: Redding Electric Utility, Redding Police Department (RPD), Redding Fire Department (RFD), Information Technology, Parks, and Geographic Information Systems. 3.

Wildfire Response A. REU Wildfire Prevention & Improved Response Program The Wildfire Prevention & Improved Response Program aims to establish a framework for the electric utility to conduct an effective, coordinated program to prevent catastrophic impact on REU's infrastructure from wildfire. During the 2024 calendar year, a number of goals and objectives were met as outlined within the Plan. 1. Goals • Prevent electric utility -caused wildfire. • Reduce the time for the Redding Fire Department to respond to and engage fires that threaten grid infrastructure and other REU facilities. • Increase staffing to respond to emergencies reasonably likely to impact REU facilities. • Increase available personnel for debris removal after extreme weather events. • Create community awareness for utility wildfire prevention. B. REU Technology Solutions Program The purpose of the REU Technology Solutions Program is to protect and reduce threats to the electric utility infrastructure and the customers who rely upon it through the application of technology. The following technologies have been identified to minimize sources of ignition, manage vegetation within the City's electric grid, harden systems, and enhance the productivity of utility staff. In addition, the listed technologies are intended to aid in the response and recovery time in the event of a wildfire, and more effectively protect the public as well as notify if an issue arises. 1. Goals • Prevent electric utility -caused wildfires. • Harden the system against the effects of fires. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 53 • Increase technology use and reliability to promote interdepartmental coordination in the event of a wildfire caused by or impacting the Redding community. • Decrease response time for emergency responders to engage in emergencies that threaten grid infrastructure and other REU facilities. C. REU Emergency Operation Program The purpose of the REU Emergency Operations Program (EOP) is to provide structured guidance for REU staff to manage emergencies effectively from an all -hazards approach. It is modeled after the ICS structure followed by the City of Redding's Emergency Operations Plan. 1. Goals • Operational readiness for staff to effectively and efficiently manage all aspects of a large emergency such as a wildfire. • Communicate timely information to all stakeholders, including staff, customers, City Management, the City Council, and the media. • Establish clear roles and tasks for REU staff within the Emergency Operations structure under Incident Command. D. REU Distribution 10 -Year Capital Improvement Program The purpose of the Distribution 10 -Year Capital Improvement Program is to enhance the distribution system by replacing specific components to reduce the probability that the system will initiate a fire and harden the electrical distribution system to better survive a fire initiated by other sources. In order to complete the necessary system hardening efforts within the required timeline, including fuse and arrestor replacement and additional circuit reclosers, contract line workers will need to be utilized to supplement REU's workforce. REU Line personnel are currently unable to take on these significant improvement projects due to the required routine maintenance of the existing infrastructure and multiple vacant positions. For a timeline of present and future improvement work items, see the chart on page 11. Listed below are specific actions taken to date to work towards the stated goals. 1. Goals • Enhanced inspections and tracking of assets. • System hardening of key subsystems. • Improved situational awareness. • System improvements providing better operational practices. 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 54 Initiative -Program Description Achievements During 2024 Goals for 2025%2026 Vegetation REU continued to fund a total of 15 Continue funding Prevention & Firefighters for improved response to Fire and Parks Response Redding wildfires One (1) Parks Superintendent, staffing to ensure t,`�1i�t££6(J1} { �J;Jt § £1t£tti££itt£f t1l{�Jl£{ltl tj tri z£ Fire and Parks two (2) Arborist Lead Workers, and four vegetation goals are Division Personnel (4) Public Works Maintenance Workers met and responses are also funded under the Wildfire to fires by fire ttffi �£ ( 13 tit t£}}ft£tri 11 (5}(f�£{ty r�tl 1 Mitigation Plan.

Audit Findings Related to CPUC Fire Threat Map • The CPUC Fire Threat map was reviewed for changes. No boundary changes were noted for the 2025 calendar year. • Previously modified 12kV circuits were evaluated for compliance with the mitigation recommendations to keep these circuits on the Circuit Recloser Enabled list. 2. Audit Findings Related to Fire Ignitions. • Number of fires caused by REU facilities: 2025 REU Wildfire Mitigation Plan Version 8.0 May 1, 2025 56 Fires Started by Calendar Year and Fire Threat Zone Calendar Year NHFTZ Tier 2 Tier 3 2023 8 The Plan requires REU to describe any fires greater than one acre. No fires related to REU infrastructure were greater than one acre in 2024. Audit Finding Related toWires Down * A wire -down event includes any instance where an electric transmission or primary distribution conductor falls to the ground or on a foreign object: Wires Down per Calendar Year and Fire Threat Zone Calendar Year NHFTZ Tier 2 Tier 3 2023 8 2. Identifying Corrective Deficiencies inthe Plan: * REU has not received any notice of deficiencies or potential deficiencies in the 2024 3. Monitoring the Effectiveness of the Inspections: • Inspection reports and progress have been reviewed quarterly for overhead lines. After creating dedicated Electrical Inspector positions, completion of critical inspections has significantly improved for both overhead & underground inspections. Additionally, REU is implementing an improved software -based Workforce Management System and GIS - based inspection program, to ensure that the inspections/repair process is being performed to industry best practices. • In 2024, REU's inspection program was audited by the CPUC. REU is taking steps to integrate the recommendations from the CPUC report into REU's inspection program, 2025KE0Wildfire Mitigation Plan Version 8.0 May 1, 2025 57 Lessons Learned to Incorporate into Future Plans w In 2024 REU contracted with an outside vegetation vendor, Arbor Pro Tree Service, to complete vegetation work throughout the calendar year. In January of2D25 a new/ vendor has been contracted to conduct vegetation work near REU infrastructure. w In 2024 REU worked with the Redding Fire Department to determine the highest wildfire threats to the City of Redding Electric Utility's infrastructure. An additional high -fire threat map was created addressing the greatest fire threats. Specific circuits were identified and placed into a heightened relay setting to reduce the risk of wildfires. (See map below) 2025KE0Wildfire Mitigation Plan Version 8.0 May 1, 2025 �� • GIS analyzed all the City -owned open space properties to determine if vegetation clearances under REU 12kv & 115kv powerlines might be expanded in the high fire - threat areas. By doubling our ROW in these high -fire threat areas, our goal of additional vegetation reduction for 2025 by the Parks Department includes: i. An additional 19 acres of clearance 12kv Primary OH Conductor ii. An additional 69 acres of clearance for 115kv Transmission Lines S.
