Diamond Bar City Council
June 21, 2022

Economic
Development Plan
An economic development plan serves as a road map for economic development decision making based on the collection of statistical data, historical perspective, and human potential.

Stormwater
Management Plan
Yes A Stormwater Management addresses flooding associated with stormwater runoff. The Stormwater Management Plan is typically focused on design and construction measures intended to reduce the impact of more frequently occurring minor urban flooding events.

Building Code Yes Community Development-Building codes and associated standards (Residential Code, Mechanical Code, Electrical Code, etc.) govern how new buildings are constructed. They are published by the state and adopted by local jurisdictions, sometimes with amendments to make the codes more locally applicable.

Mitigation actions including buildings be constructed to a higher standard that they may better withstand damage during a hazard event. Such actions may be incorporated into future Building Code updates.

Subdivision
Regulation
Yes Community Development-A subdivision ordinance is intended to regulate the development of housing, commercial, industrial, or other uses including associated public infrastructure -- as land is subdivided into buildable lots for sale or future development.

Zoning Yes Community Development-Zoning manages how land use is controlled by local governments. As part of a community’s enforcement efforts, zoning is used to protect the health, welfare, and safety of the public, generally by implementing a Zoning Ordinance. Since zoning regulations enable municipal governments to limit the type and density of development, it may serve as a powerful tool used to protect people and property located in identified hazard areas.

Hillside Management Yes Community Development-The Hillside Management Ordinance is part of the City’s municipal code.

Flood Damage

90 Administrative and Technical Capability
The ability of a local government to develop and implement mitigation projects, policies, and programs is contingent upon its level of staffing and other available resources.

Administrative capability is determined by evaluating whether there are an adequate number of personnel to complete mitigation activities. Similarly, technical capability can be evaluated by assessing the level of knowledge and technical expertise of local government employees, such as personnel skilled in planning, engineering and building codes. As part of the plan update process, the HMC reviewed and updated any changes that have occurred in the City’s level of administrative and technical capabilities since the last plan update. As applicable, these changes were reviewed by the HMC during the LHMP update process.

Administrative and technical resources available to the city to support the implementation of hazard mitigation management actions are listed in Table 39: Administrative and Technical Capabilities.

93 Fiscal Capability
The ability of a local government to implement mitigation activities is often tied to funding available to establish policies and implement projects. Such funding generally comes from local revenue and financing and from outside grants. Costs associated with mitigation activities range from staffing and administrative costs to those required for project implementation. As part of the plan update process, the HMC reviewed and updated changes that have occurred in the City’s fiscal capabilities since the last plan update.

Financial resources (other than grants) available to the City to support the implementation of hazard mitigation management actions are outlined in Table 40: Fiscal Capabilities.

NATIONAL FLOOD INSURANCE PROGRAM CONTINUED

COMPLIANCE
Diamond Bar participates in the National Flood Insurance Program (NFIP), which was created by Congress in 1968 to provide flood insurance at subsidized rates to homeowners who live in flood-prone areas. Community NFIP participation is optional, although property owners who live in nonparticipating communities that have FEMA mapped Special Flood Hazard Areas (flood-prone areas) will not be able to buy flood insurance through the program. Additionally, nonparticipating communities with mapped floodplains cannot receive federal grants or loans for development activities in flood-prone areas, and they are ineligible to receive federal disaster assistance to repair flood-damaged buildings located in mapped floodplains. Diamond Bar has participated in NFIP since 1980.

Although program participation is not a hazard mitigation action to be included in the mitigation strategy per se, the City will continue to participate in NFIP and continue

7.1.b
Packet Pg. 353
2022 City of Diamond Bar Local Hazard Mitigation Plan
94 enforcement of the City’s Floodplain Management regulations (Municipal Code Section

18.108.110-210). This includes:
 Identifying the purpose of the floodplain regulation(s), as well as current and proposed ways to reduce flood losses.
 Serving as a mechanism for identifying flood hazard areas and related flood mapping issues.
 Oversees permit requirements for current and projected development projects.  Inspect all development for continued compliance with city code.  Applies development standards for flood-prone areas that minimize personal injury and property damage; and maintains documentation and risk analyses required for projects developed in these areas.
 Assist residents in obtaining information on flood hazards, flood maps, flood insurance and proper mitigation measures.

In an effort to meet NFIP requirements, Diamond Bar will make updates and revisions to Floodplain Management regulations as it deems necessary. These updates and revisions may be prompted by changes in local demographics; shifts in land use; trends such as the frequency and intensity of flood events; and other factors that may warrant municipal action.

The city will also continue to incorporate into future planning documents, including HMP updates, changes to the locations and designations of mapped floodplains.

The City of Diamond Bar contains Special Flood Hazard Areas where 10 NFIP policies are in force. Total insurance coverage for these policies amounts to $2,910,000; however, no repetitive loss properties were identified by the City’s Floodplain Administrator. The city does not participate in the voluntary Community Rating System (CRS).

95 Section 6: Mitigation Strategy
C. Mitigation Strategy
C1. Does the plan document each jurisdiction’s existing authorities, policies, programs and resources and its ability to expand on and improve these existing policies and programs? (Requirement §201.6(c)(3))
C2. Does the Plan address each jurisdiction’s participation in the NFIP and continued compliance with NFIP requirements, as appropriate? (Requirement §201.6(c)(3)(ii)) C3. Does the Plan include goals to reduce/avoid long-term vulnerabilities to the identified hazards? (Requirement §201.6(c)(3)(i))
C4. Does the Plan identify and analyze a comprehensive range of specific mitigation actions and projects for each jurisdiction being considered to reduce the effects of hazards, with emphasis on new and existing buildings and infrastructure? (Requirement §201.6(c)(3)(ii))
C5. Does the Plan contain an action plan that describes how the actions identified will be prioritized (including cost benefit review), implemented, and administered by each jurisdiction? (Requirement §201.6(c)(3)(iv)); (Requirement §201.6(c)(3)(iii)) C6. Does the Plan describe a process by which local governments will integrate the requirements of the mitigation plan into other planning mechanisms, such as comprehensive or capital improvement plans, when appropriate? (Requirement §201.6(c)(4)(ii))
The Mitigation Strategy
The Mitigation Strategy provides the blueprint for the participating jurisdictions to use in its goal of improving disaster resiliency by lessening vulnerability to identified hazards of concern. Identified Mitigation Goals and Objectives inform the development of appropriate mitigation strategies, or actions and initiatives, designed to avoid, minimize, and mitigate the impacts of natural and manmade disasters on the local population and property located in the planning area. Communities strengthen their resiliency by issuing building codes, zoning ordinances, and other regulatory activities. When communities review or update these planning mechanisms, the opportunity exists to identify whether mitigation strategies can be incorporated into policy changes. Such efforts go a long way to ensuring that the City will remain resilient when affected by known hazards.

HMC members participated in a virtual meeting on May 22, 2021, to start the mitigation strategy review. Topics covered include:
 A review and update of the Goals and Objectives from the 2004 LHMP.  Discussion of strategies included in the 2004 plan and the status of each mitigation action.
 Input about whether each 2004 action should be carried forward and included in the 2022 LHMP if not, the reason why.
 New mitigation strategies to be included in the updated plan.  Developing a minimum of two mitigation actions - each outlined in a mitigation action worksheet to fully describe a current or proposed mitigation strategy, including how the community benefits from each action implemented.

7.1.b
Packet Pg. 355
2022 City of Diamond Bar Local Hazard Mitigation Plan
96 The HMC decided that the planning area mitigation priorities should remained the same, but the Goals and Objectives and list of mitigation actions could be streamlined.

Goals and Objectives
The updated Goals and Objectives were also reviewed to ensure that they broadly align with the goals of the City’s General Plan, 2019 Los Angeles County Hazard Mitigation Plan, and 2018 State Hazard Mitigation Plan (SHMP).

Table 37: 2022 City of Diamond Bar LHMP Goals and Objectives 2022 Diamond Bar Local Hazard Mitigation Plan Goals and Objectives Goal 1: Protect Life and Property

2022 City of Diamond Bar Local Hazard Mitigation Plan
97 The City completed a two-part process to update the Mitigation Action Plan strategy for the 2022 plan update:
 The HMC considered the findings of the risk and capabilities assessments to consider new mitigation actions/measures.
 The group reviewed and provide updates on the status and relevance of each action provided in the previous plan to determine which measures have been completed; would be carried forward to the 2022 Plan; or deleted. This also included a discussion of changes in local priorities since the last plan update. Documentation of this process is provided as Worksheet 4 in Appendix D.

Incorporation into Existing Planning Mechanisms
The primary mechanism for incorporation of the mitigation plan requirements is through the City’s General Plan. Other key plans for incorporation includes, but are not limited to:
 Diamond Bar Emergency Operations Plan (EOP), which focuses on the effective preparedness and response to hazard events that occur within the city.

Incorporation of relevant content from this plan into the EOP ensures consistency regarding the hazards addressed in both plans.
 Diamond Bar Capital Improvement Plan (CIP) identifies key infrastructure investments throughout the city that may include hazard mitigation elements.

Incorporation of mitigation planning elements into the CIP may assist with enhancing infrastructure investment through additional funding and/or modification of improvements to include hazard mitigation elements.

Review and Evaluation of a Range of Mitigation Actions
The process of selecting and prioritizing mitigation actions began with each member of the HMC developing a “wish list” that considered community survey responses and stakeholder input. Individual “wish lists” were consolidated into a single list of mitigation actions/projects.

To narrow down the list to measures/actions for inclusion in the 2022 LHMP update, the HMC initially considered three criteria:
 What actions had the most serious consequences if not implemented?  What actions could be implemented by existing staff with funding resources available internally (or externally)?
 What actions responded to the primary concerns of the community? Mitigation actions are specific projects, activities, and processes taken to reduce long-term risk and lessen impacts to people and property from identified hazards. Implementing mitigation actions helps the community achieve the plan’s primary goal of fostering risk reduction. The primary types of mitigation actions that were considered include:
 Local plans and regulations
 Structure and infrastructure projects
 Natural system protection and education
 Community awareness programs
Building on the mitigation actions identified in the City’s General plan and the previous LHMP, the HMC reviewed and analyzed a comprehensive range of mitigation actions and

7.1.b

98 projects. This HMC consulted the FEMA resource Mitigation Ideas: A Resource for Reducing Risk for Natural Hazards (January 2013) to expand the scope of activities for consideration.

The comprehensive range of potential activities included in Mitigation Ideas enabled the HMC to analyze and evaluate different mitigation measures, including a mixture of structural and non-structural activities. In general, all activities considered may be classified under one of the following six (6) broad categories of mitigation techniques provided in Table 43:

Mitigation Actions/Techniques.

Table 38: Mitigation Actions/Techniques
Mitigation
Actions
Techniques
Description
Prevention Preventative activities are intended to keep hazard impacts from worsening and are typically administered through government programs or regulatory actions that influence the way land is developed and buildings are built. They are particularly effective in reducing a community’s future vulnerability, especially in areas where development has not occurred, or capital improvements have not been substantial.

Examples includes planning and zoning, building codes, open space preservation, floodplain regulations, stormwater management regulations, drainage system maintenance, capital improvement programs, and riverine/fault zone setbacks.

Property
Protection
Property protection measures involve the modification of existing buildings and structures to help them better withstand the forces of a hazard, or removal of the structures from hazardous locations.

Examples include property acquisition and demolition; structure relocation; building elevation; critical facilities protection; retrofitting (e.g., wind proofing, floodproofing, seismic design techniques, etc.); the addition safe rooms, shutters, and shatter- resistant glass; and purchasing property insurance.

Natural
Resource
Protection
Natural resource protection activities reduce the impact of natural hazards by preserving or restoring natural areas and their protective functions. Such areas include floodplains, wetlands, steep slopes, and sand dunes. Parks, recreation, or conservation agencies and organizations often implement such protective measures. Examples include floodplain protection; watershed management; riparian buffers; forest and vegetation management (e.g., fire resistant landscaping, fuel breaks, etc.); erosion and sediment control; wetland preservation and restoration; habitat preservation; and slope stabilization.

Structural
Projects
Structural mitigation projects are intended to lessen the impact of a hazard through construction projects. They are usually designed by engineers and managed or maintained by public works staff. Examples include reservoirs; dams/levees/dikes/floodwalls;
diversions/detention/retention; channel modification; and building and maintaining storm sewers systems.

Emergency
Services
Although not typically considered a “mitigation” technique, emergency service measures minimize the impact of a hazard event on people and property. These commonly are actions taken immediately prior to, during, or in response to a hazard event. Examples include warning systems; evacuation planning and management; emergency response training and exercises; sandbagging (flood protection; and installing temporary shutters to provide wind protection.

Public
Education and
Awareness
Public education and awareness activities are used to advise residents, elected officials, business owners, potential property buyers, and visitors about hazards, hazardous areas, and mitigation techniques they can use to protect themselves and their property. Examples of measures to educate and inform the public include outreach projects; a speaker series or demonstration events; information about hazard mapping; real estate disclosures; resources made available in the public library; educational programs for children; and hazard expositions.

Mitigation Approach
In developing and ranking the 2022 mitigation actions, the City elected to use the FEMA recommended STAPLEE evaluation criteria tool as outlined in the FEMA Local Mitigation Planning Handbook (March 2013). Each criterion is shown below.

Table 39: STAPLEE Mitigation Ranking Criteria
STAPLEE Mitigation Action Ranking Criteria
Used in the 2022 City of Diamond Bar Hazard Mitigation Planning Process Criteria Description
S Social Consider public acceptance and support of the mitigation measure T Technical Evaluate whether the proposed action is technically feasible A Administrative Evaluate the anticipated staffing, funding, and maintenance requirements of the mitigation measure
P Political Determine the local political leadership’s support of the mitigation measure
L Legal Evaluate the community’s legal authority to implement a mitigation measure
E Economic Consider the cost-effectiveness of the action, potential funding sources, and the potential impact on local economic conditions E Environmental Evaluate how the action affects local environmental concerns Source: FEMA Local Hazard Mitigation Planning Guide
As part of the economic evaluation of mitigation action, participants analyzed actions in terms of the overall costs, measuring whether the potential benefit to be gained from the action outweighed all costs associated with it. As a result of this exercise, priority was assigned to each mitigation action by marking them as High (H), Moderate (M), or Low (L). An action that is ranked as “High” indicates that the action will be implemented as soon as funding is received. A “Moderate” action may not be implemented right away depending on the cost and number of citizens served by the action. Actions ranked as “Low” indicate that they will not be implemented until “High” and “Moderate” actions have been considered for funding, or, a future disaster occurs that moves the ranking of the action to a higher priority.

Mitigation Action Plan
The mitigation action plan identifies short and long-term action items developed based on hazard data collection and research, and the public participation process, including the use of a community survey. Mitigation actions may be considered for funding through federal, state and local funding sources. A detail list of potential funding sources is provided in Appendix F. To ensure that each identified activity is implemented, each action item includes information on the expected timeline and the coordinating agency or position. Upon implementation, the coordinating agency may look to partner with other organizations for resources and technical assistance.

City of Diamond Bar Local Hazard Mitigation Plan-2022
Section 7: Plan Maintenance
The formal plan maintenance process that will ensure the City of Diamond Bar 2022 Hazard Mitigation Plan is implemented, monitored, evaluated, and updated so the plan remains a dynamic relevant document. The plan maintenance process includes a schedule for monitoring and evaluating the Plan annually and producing a plan revision every five years. This section describes how the City will integrate public participation throughout the plan maintenance process. It consists of the following subsections

1. Overview.

2. Monitoring, Evaluating and Updating.

3. Incorporation into Existing Planning Mechanism.

4. Method for Continued Participation.

Plan Maintenance Overview
The City Manager’s Office will serve as the lead agency responsible for implementing the plan maintenance process. The City’s HMC will be responsible for implementing the strategies outlined in this Plan, and for updating and maintaining the Plan according to the guidelines set forth below. The city will use the Plan’s goals, as well as continued analysis of hazard risks and capabilities, to weigh the availability of community resources against the cost and benefit for each mitigation action. That is to say, the action will be reviewed against the staff time and financial resources needed to implement it. The city understands the value of this Plan and the extent to which plan elements lend themselves to mitigating hazards of concern. The City intends to maintain, update, and implement the 2022 HMP using the following method and schedule.

Monitoring, Evaluating and Updating the Plan
The City of Diamond Bar HMC will keep the Plan current by monitoring, evaluating, and updating the Plan. FEMA defines these efforts as follows:

1. Monitoring: Tracking the implementation of the plan over time.

2. Evaluating: Assessing the effectiveness of the plan at achieving its stated purpose and goals.

3. Updating: Reviewing and revising the plan at least once every five years.

The City Manager’s Office is the oversight entity charged with ensuring that the Plan maintenance process is carried out. The City’s HMC is the planning group responsible for promoting ongoing coordination and community participation in the Plan maintenance process.

Monitoring the Plan
As directed by the City Manager or his/her designee, the City’s HMC representatives will collect information needed to monitor the Plan and revise it as needed.

Packet Pg. 372
2022 City of Diamond Bar Local Hazard Mitigation Plan Section 7- PLAN MAINTENANCE 113
Section 7- Plan Maintenance
City of Diamond Bar Local Hazard Mitigation Plan-2022
Each mitigation action in this Plan is prioritized and assigned to a specific department, agency, or position, who will carry out the action when staff time and funding are available to support the action. Timelines are given for each mitigation action, where appropriate, and potential funding sources are identified. Additionally, each mitigation action is prioritized based on a common set of criteria, which enables jurisdictions to move specific actions forward as funding opportunities arise. Annual plan monitoring will help track progress on each proposed mitigation action.

The role of City Manager or his/her designee includes the following tasks:
 Schedule an annual meeting of the HMC.
 Develop meeting agendas.
 Schedule post-disaster event meetings with the HMC for Federally- and/or State declared disasters that result in significant damage sustained, or if the event revealed planning area vulnerabilities that need to be addressed.
 Provide information about recent hazard impacts and the current status of mitigation actions.  Invite other agencies/departments/stakeholders and the public to participate in meetings.  Coordinate with the HMC to communicate plan updates to the public when applicable. This may include activities such as, but not limited to, developing Plan amendments; completing mitigation actions; notifying the public of available mitigation program; and related efforts.

During annual meetings, the City’s HMC will address hazard-related concerns that may have arisen since the most recent Plan update; assess events affecting the city to determine if changes in the plan are required; and complete the monitoring and evaluation worksheets developed for the purpose of documenting the monitoring process.

If significant changes, updates, or amendments to the Plan are suggested by the City’s HMC, they will be documented and included as part of the Plan’s annual update.

Evaluating the Plan
The City Manager or his/her designee and the members of the City’s HMC will use the Plan Evaluation Checklist, (which is included in Attachment G), to evaluate the Plan and make recommendations for future Plan updates and enhancements. The Checklist will be completed annually.

The Plan Evaluation Checklist includes the following components:
 Evaluate the goals and objectives to ensure they address current and expected conditions.  Determine any changes in the nature or magnitude of risks identified in the Plan.  Evaluate current resources for adequacy in implementing the Plan.  Document implementation problems experienced by other agencies, including technical, political, legal or coordination issues.
 Evaluate the effectiveness of the HMC.

Three additional worksheets were developed and are included as attachments to this section.  Attachment B: Planning Considerations Worksheet.
 Attachment C: Mitigation Action Implementation Worksheet (listing status of mitigation actions identified by each jurisdiction).

 Attachment D: City of Diamond Bar HMC Meetings and Public Involvement Activities Log.

The Plan Evaluation Checklist, Planning Considerations Worksheet, and Mitigation Action Implementation Worksheet will be completed annually (at a minimum) and stored in Appendix G.

Updating the Plan
In accordance with federal regulations, the city’s LHMP is to be updated every five years. The City Manager or his/her designee will complete an annual progress report, as described in the Evaluation Section above, to improve the documentation of the progress made by the City on the strategies defined in this Plan. In doing so, the Plan will become more of a “living document” that is proactive and integrates with the planning area’s future initiatives.

Plan reviews will provide the city with an opportunity to evaluate those actions that have been successful, and to document potential losses avoided due to the implementation of specific mitigation measures. The plan review also provides the opportunity to address mitigation actions that may not have been successfully implemented as assigned and determine how they could be more feasibly implemented.

If a significant hazard event occurs, or if changes in regulations warrant an update of the Plan, the City Manager or his/her designee will meet with the HMC to determine the course of action to be used to update the Plan. If a Plan update is approved, the same procedures used in developing the original plan will be followed and will incorporate opportunities for the pubic to have input and provide comments.

Incorporation into Existing Planning Mechanisms
Althrough the General Plan is the primary method of incorporating the LHMP into other planning mechanisms, the Capital Improvement Plan, and Building and Safety Codes will also incorporate mitigation actions as appropriate.

The integration process and schedule of incorporating elements of this Plan will vary based on the specific plan’s update cycle. The yearly mitigation meetings will provide an opportunity to track the progress on the integration of this Plan into local planning mechanisms.

Method for Continued Public Participation
Diamond Bar is dedicated to involving the public directly in the continual review and updates of the LHMP. Copies of the Plan will be catalogued and made available at City Hall and Los Angeles County Diamond Bar Public Library. The existence and location of these copies will be publicized in the Diamond Bar City News newsletter.

Public comments related to the Plan will be retained in the City Manager’s Office. In addition, copies of the Plan and any proposed changes will be posted on the city website. This site will also contain an email address and phone number to which people can direct their comments, recommendations, and concerns.

Additionally, if significant changes are required of the plan by CalOES/FEMA, the City HMC will notify the public and encourage their participation in meetings to provide input and review any changes. The City HMC may also send notifications to the public on plan amendments, completion of mitigation actions, and notification of programs available for mitigation. To this end, the public will remain involved in the implementation of this plan.

Public involvement during the plan’s monitoring and evaluation process will be fostered through the strategies listed below:

Introduction:

Mr. Thompson introduced himself and asked to do a roll call for the beginning of the meeting. He discussed the agenda and what will be covered in the presentation continues and when we get to the end of the agenda, we will cover what additional hazards should be included in the updated plan.

Mr. Santos and Mr. Thompson will be working hand in hand through this process and the participants are encouraged to reach out to either as needed with questions or concerns and provide feedback.

Question- asked to have the presentation emailed to them at the end of the presentation Answer- Yes, we will email them after the meeting
Hazard Overview
Mr. Thompson proceeded to provide the FEMA definition and overview of hazard mitigation, mitigation planning and the mitigation related grants. Mr. Thompson stated that we will discuss several of the FEMA Hazard Mitigation Assistance grants to include BRIC and other assistance grants in later slides. He also discusses the

Section 7- Plan Maintenance
City of Diamond Bar Local Hazard Mitigation Plan-2022
Great Floods or Noah and the Arch. In this example he discussed how Noah followed a planning process similar to the one we will use to update the City’s plan.

Noah assessed the hazard-flooding, reviewed a comprehensive list of actions, selected best action and hazard was avoided.

Project Background/Objectives
Mr. Thompson continued and discussed the project background as well as the project objectives. These discussions included why the city needs to update its current 2004 hazard mitigation plan (HMP) to a new 2021 hazard mitigation plan. He also discussed the Disaster Mitigation Act of 2000 (DMA2K) as being the primary reason to be moving forward in updating this plan, and the benefits of having an up-to-date plan. In order to be eligible for FEMA Hazard Mitigation Assistance (HMA) funds a community must have a FEMA approved hazard mitigation plan. A current FEMA approved HMP will allow the City to be eligible for grants/funding to address some of the mitigation actions/projects that will result from our planning process.

This was followed with a discussion of the project objectives which included assuring that at the end of the planning process the City will have a FEMA approvable plan. This includes identifying hazards of concerns, greatest opportunities to reduce risk and fulfill public input requirements.

Mr. Thompson also stressed that it is the city’s plan, IEM staff is working on and making sure it is your plan not IEM plan when it’s completed. Mr. Thompson also stated we want to make sure the planning requirements are met and will be beneficial to the City moving forward.

Plan Section
Mr. Thompson proceeded and open a discussion on the planning process to include 5 planning phases/tasks.

These phases/tasks include planning process, hazard identification and risk assessment, mitigation strategy, plan maintenance, final draft plan.

He continued to review the steps and related activities that will be completed under each of the identified plan phases/tasks.

Phase 1-Planning Process
Mr. Thompson discussed activities that will addressed under this phase to include building the team, document how the plan is being updated, determine an outreach strategy, identify the capabilities assessment to include plans, programs policies regulations that can impact city’s ability to implement hazard mitigation program (what already exists). He also highlighted this part of the process will be data intensive and cross over the entire planning cycle.
• Establish a formal planning process
• Build the Team-Participation from a broad range of stakeholders • Documentation of planning activities
• Meetings (group, virtual, one-to-one)
• Input from Planning Committee and Stakeholders
• Integration with other state planning efforts
• Create an Outreach Strategy
• Capabilities Assessment - Existing policies, studies, plans, programs, etc.) Data Reviews and Collection
Statement and Question: Robert Cruz- mentioned community input and asked will it be in person meetings, and once finalized is the outcome going to be on the city website.

Answer: Mr. Thompson- initially we proposed a survey to the public about the plan and their feedback on what should be covered in it and posting the activities on the city website.

Second Answer: Mr. Santos- intent to post where we are going with the grant and progress on the website, and want to make sure that once approved it goes on to the website and maintenance as well after the 5 year Phase 2- Hazards Identification and Risk Assessment
Phases/Tasks 2- Hazards Identification and Risk Assessment- Mr. Thompson provided that the activities include a discussion on identifying and profiling hazards and the completion of a detail risk assessment.

Hazards Identification: Mr. Thompson discussed the need to identify and profile each hazard that can impact the city. He also reviewed the hazards identified in previous 2004 plan and stated that we will further discuss hazards later in the presentation.

Section 7- Plan Maintenance
City of Diamond Bar Local Hazard Mitigation Plan-2022
Risk Assessment: Mr. Thompson discussed the elements to be included in the risk assessment to include critical facilities and updating capabilities assessment, impacts of changes in development, impacts of climate change and estimated losses.
• Critical facilities-lifelines includes a review and assessment of the City’s critical facilities and infrastructures and their vulnerable to identified hazards as well as vulnerable populations. This will also include a discussion of NFIP repetitive loss properties.
• Capabilities assessment will include a review of current regulations, that will support or hinder mitigation actions; Administration or government support; Education and outreach- is there a process to educate them or a way to disseminate information to them. NFIP- make sure it is addressed to meet FEMA requirements, participation, continued participation, and repetitive loss structures. The outcome is to assess the City’s ability to implement long term mitigation action plans, look at what is in place and if there is a conflict, and administrative capabilities to do them.
• The final section of the risk assessment will include a summary of potential losses.

Phases/Tasks 3- Mitigation strategy- Mr. Thompson provided that the risk assessment forms the foundation to this task. He reviewed the various steps involved in developing mitigation strategy and the mitigation action plan.

The Mitigation Strategy will include:
o Goals and objectives- see if the old goals and objectives are still relevant or what needs to be removed or added
o Review a comprehensive range of mitigation actions, from prevention, to protection, mitigation actions, etc.
o How to mitigate the hazards and repetitive loss structures, o Development of the mitigation action plan, what are we vulnerable to, what are the risks, prioritizing the projects, who is responsible, time frame for completion of those projects, o Work with them on the top 2 actions to give them an idea of how this works and needs to be completed.

Mr. Thompson also discussed the need to develop a strategy to address repetitive loss properties stating that FEMA is concern when it comes to flooding
He discussed the mitigation action plan to include all of the actions or projects that are considered important to the community and put them in a prioritized order to include time frame for completion, who is responsible for action and funding source.

There was also a discussion of Hazard Mitigation Assistance (HMA) funding sources from FEMA o PA-406-mitigation provides post-disaster funds that can be used to make additional improvements/upgrades to damage public structures where applicable and can provide mitigation actions that might not have been covered before.
o 404-Hazard Mitigation Grant Program (HMGP) provides post-disaster to complete mitigation related actions/projects.
o Flood Mitigation Assistance (FMA) provides pre-disaster funding to address retrofitting to flood-prone structures and infrastructure. These funds are provided on annually. o Pre-Disaster Mitigation (PDM)/ Building Resilient Infrastructure and Communities (BRIC) provides funding for mitigation related projects with an added focus on infrastructure projects.

Question: (Chat question) Robert Cruz- any assistance programs for earthquakes? Answer: Leroy- Yes there is funding for those.

Phases/Tasks 4- Plan Maintenance
Mr. Thompson discussed the plan maintenance process to include monitoring, evaluate and update the plan.

This section will include maintaining and updating the plan as well as tracking and reporting the status mitigation actions/projects.

Phases/Tasks 5- Draft Plan and Review Process
Mr. Thompson reviewed the process for developing the draft plan, approval by the planning committee (city of diamond bar) and then to the State OES and then to FEMA. If comments come back, we will handle them and

7.1.b
Packet Pg. 382
2022 City of Diamond Bar Local Hazard Mitigation Plan Section 7- PLAN MAINTENANCE 123
Section 7- Plan Maintenance
City of Diamond Bar Local Hazard Mitigation Plan-2022
then send it back up to the state and then to FEMA and back again if is necessary. After final approval the community approves it then you get the final approved paperwork from FEMA The plan is not official until the city adopts the plan after FEMA approves it pending adoption.

What we want to do is finish a section and get that approved as we go along to quicken the process towards approval.

Roles and responsibilities
Mr. Thompson informed the participates that the Planning Coordination Team will include the City’s Point of Contact Anthony Santos or Dannette Allen, and IEM’s Point of Contact Leroy Thompson and Sheila Hascall being the second point of contact for IEM.

The Planning Team will include all individuals who participates in the planning process. The Team will additional subject matter experts, stakeholders, specialists as well as the public. o The plan should reflect the community and its needs.
o Comments from neighboring community comments so that we have it all covered o We will review the State HMP and the LA County HMP to make sure the City’s plan is consistent with statewide mitigation programs.

Timeline/Schedule
Mr. Thompson reviewed the project timeline and potential meeting schedule noting that they are tentative and can change. We also discussed the ability to add additional persons to the Planning Team if necessary.

Mr. Santos discuss conducting a potential work session/meeting with the City Council to make them aware of where we are in the process. He is not sure of the format of such meeting but will get back with the Team later. o Can add personnel if you think of others who want to participate, o Anthony- council planning workshop
o Update the council that they are working in the plan and that they are aware of where we are in the process, can be a study session if needed to discuss things more detailed, Review of Potential Hazards
Mr. Thompson asked the Team if additional hazards should be added to the plan. Mr. Santos stated that we can consider other human caused hazards to include COVID-19 and Hazardous Materials. Mr. Thompson asked about any type of hurricane force winds and Mr. Santos stated that they experience Sana Ana winds and had wildfires in 2020.

Next Steps
• Mr. Thompson stated that we will attempt to reuse as much data as possible from the 2004 plan and see what is still current and what needs to be updated. He additionally, he provided that we will be doing a series of one on one discussions with different agencies and team members to assist in our data collect efforts. • One of the first documents that we will be sending out is a survey of critical facilities that are in the 2004 plan and requesting assistance in updating information. We will work with the City to remove any sites from the list that do not reported for various reasons.
• Mr. Thompson provided an example of how we will move forward using flood hazard as an example. He stated we might have an individual meeting with Building and/or Public Works to discuss areas in community that flood on a routine base and are not included on the City’s FIRM.

Questions/Comments
• Mr. Santos – thanks the attendees for participating in the meeting and reminded the group to ask questions nothing is unimportant
• Mr. Thompson- we will be working with you to make sure all FEMA requirements are met and that it’s your plan not our plan

APPENDIX D: Public Engagement
Public Engagement
Under FEMA guidelines, local hazard mitigation planning processes should create opportunities for members of the public to be involved in plan development—at a minimum, during the initial drafting stage and during plan approval. The HMC developed a virtual engagement strategy to guide all public engagement activities.

However, due to issues with COVID-19, in lieu of originally planned in-person public meeting were not able to be conducted. However, the City posted an online community survey on its website soliciting public comments/input on the planning process. The survey was posted online at https://www.allcounted.com/s?did=cfl5vyu9y58d7&lang=en_US. The figure below shows how the City announced the survey on its web site. The Community Survey was posted on the web site for two reasons:
to inform the general public that the 2022 LHMP was being updated; and to invite the public to give input on hazards of concern and how they have been affected by recent disaster events. The results of the Community Survey have been incorporated into the respective sections of the plan.

City announced the survey on its web site.

A disaster communication system that leverages technologies and methods not reliant on cell phone or an digital service. At combination of radio system and community volunteers to spread communication.

It is imperative that the City of Diamond Bar stop suing it’s residents for failing to mitigate or repair hillsides and slopes. In most cases the mitigation and repair requirements are beyond the affordability of most home owners in the area. These homes were built and sold in the 60’s and 70’s and mother nature is taking her toll on the surrounding landscape, which is not within the home owners control. Financial assistance and grants need to be made available to ALL residents regardless of their income. Landslide repair can cost in excess of $100K.

The city posted a draft copy of the Plan on its website for public review and comments.

Hazard Scoring and Prioritization Methodology

HAZARD SCORING AND PRIORITIZATION
The HMC followed FEMA guidance for hazard mitigation plans and prioritized each of the 8 hazards. In the initial step, it assigned a score of 1 to 4 for each of the 10 hazards. The four criteria are provided in Table 10.

Table 10: Risk Character shows the Criterion Scoring used to assign a score for each criterion.

RISK CHARACTERISTIC (VULNERABILITY) SCORE

probability to determine the final score for each hazard. A final score between 0 and 12 is considered a low-threat hazard, 12.1 to 42 is a medium-threat hazard, and a score 42 and above is considered a highthreat hazard. This final score determines the prioritization of the hazards.

Based on the Total Risk Score, each hazard is determined to be of Low, Moderate, or High concern to the City of Diamond Bar.

Table 13: RISK LEVEL TOTAL RISK SCORE
Low 0-15
A hazard with a LOW RISK rating is expected to have little to no impact upon the jurisdiction. The hazard poses minimal health and safety consequences to the state’s residents and is expected to cause little to no property damage. The occurrence of a hazard with a LOW RISK rating is rare; however, due to other factors such as geographic location it is still possible for such a hazard to occur and cause even significant damage based upon the magnitude of the event.

Moderate 16-30
A hazard with a MODERATE RISK rating is expected to have a moderate impact upon the jurisdiction. The hazard poses minor health and safety consequences with minor injuries expected and few to no fatalities.

The hazard may cause some property to be damaged or destroyed. The occurrence of a hazard with a MODERATE RISK rating is likely at least once within the next 25 years.

High 31 or More
A hazard with a HIGH-RISK rating is expected to have a significant impact upon the jurisdiction. The hazard poses high health and safety consequences with numerous injuries and fatalities possible. The hazard may cause even some property to be damaged or destroyed. A hazard with a HIGH-RISK rating is expected to occur at least once within a 12-month period but can occur multiple times within a year.

federal agencies and other interested parties.

Creation of a CWPP can specifically address a
community’s unique conditions, values, and priorities
related to wildfire risk reduction and resilience.

Communities with CWPPs in place are given priority for

Proposition 1E: Disaster
Preparedness and Flood
Prevention Bond Act of 2006
In addition to the general fund, bonds are an important source of state funding for flood hazard mitigation projects. Among the largest is the voter‐approved $4.09 billion Proposition 1E (the Disaster Preparedness and Flood Prevention Bond Act of 2006) to fund flood management projects, including repairs and improvements to levees, weirs, bypasses, and other flood control facilities throughout the state. Proposition 1E allocates $3 billion to repair and improve state-federal facilities that are part of the State Plan of Flood Control for the Central Valley and to reduce the risks of levee failure in the Sacramento‐San Joaquin Delta.

Of these funds, a minimum of $1 billion will be allocated to high‐level flood protection for urban areas protected by state‐federal project levees, $300 million to design flood level protection for non‐urban areas protected by statefederal project levees, and a minimum of $500 million to reduce the risks of levee failure in the Sacramento‐San Joaquin Delta.

Also allocated are $500 million for State Flood Control Subventions and $300 million in storm water Flood Management Grants. Annex Table 2.N summarizes the purpose of allocated Proposition 1E dollars and funding levels.

Annex
Proposition 1: The Water
Quality, Supply, and
Infrastructure Improvement Act
of 2014
In 2014, California voters approved the Water Quality, Supply, and Infrastructure Improvement Act of 2014 (Proposition 1) authorizes $7.545 billion in general obligation bonds to fund ecosystems and watershed protection and restoration, water supply infrastructure projects, including surface and groundwater storage, and drinking water protection. Table 2.O illustrates funding status of Proposition 1 programs.

Many of the projects funded through Prop 1 further implement the California Water Action Plan, which, outlines the
State’sroadmaptowardsustainablewater management since2014.

Thisfunding has gonetoprojectsforwatershed restoration throughout the State. Specific examples include the American River Headwaters Restoration Project ($1.8 million), Napa River Restoration Oakville to Oak Knoll Project ($800,000) and appropriations to regional water agencies and conservancies, such as the Department of Water Resources and the San Diego River Conservancy.

Local agencies have already proposed mitigation and levee strengthening projects in the amount of $204 million related to funds from Propositions 1E and 84.

PLAN ASSESSMENT
A. Plan Strengths and Opportunities for Improvement
This section provides a discussion of the strengths of the plan document and identifies areas where these could be improved beyond minimum requirements.

Element A: Planning Process
Opportunities for Improvement:
1) While there was a brief mention that neighboring jurisdictions were given the opportunity to participate (ref. p.20), it was unclear which jurisdictions were invited, when, how, and who their representative was. Given the overlapping location and extent of hazards, as well as the benefits of pursuing joint mitigation actions, we strongly encourage jurisdictions to strengthen partnerships with neighboring jurisdictions to advance mutually beneficial actions.
2) In future updates, consider expanding planning committee participants to include community planners, economic development, and elected officials. These officials often have direct involvement in areas which are key to integrating the LHMP with local decisionmaking processes. While not always possible, LHMPs and mitigation actions are strengthened when local elected officials are involved in the planning process.

Element B: Hazard Identification and Risk Assessment
Strengths:
1) Great use of the ‘community lifelines’ framework to discuss areas of vulnerability for each hazard.
2) Good use of HAZUS-MH to estimate potential losses from catastrophic earthquakes.

Consider incorporating a finer-scale analysis of building inventories (to include residential structures) to determine and map potential damages and mitigation actions based on building types. This in-turn aids the evaluation of possible emergency response needs and actions.

Opportunities for Improvement:
1) Consider exploring and including data sources that break-down hazards, impacts (including past losses), and risk at the local level. Consider the use of data at the county or census tract level (ref. Spatial Hazard Events and Losses Database – SHELDUS; FEMA’s National Risk Index) in future updates.
2) Consider a finer detail analysis of community exposure and vulnerability to each hazard.

For instance, in addition to mapping areas of wildfire risk and identifying the number/cost of buildings exposed, consider a table/matrix and map identifying the number of residents

7.1.d
Packet Pg. 430
12 FEMA Region IX Local Mitigation Plan Review Tool
exposed, number/location of vulnerable populations, type/location of fire-prone vegetation, building densities, etc. These quantitative measures, in conjunction with a qualitative assessment, would aid in the development and prioritization of mitigation actions.
3) Categories of severe weather that are distinct phenomena (e.g. extreme heat, freeze, or storms by type) always need to be profiled out separately if they are high priority or have a mitigation action identified
Element C: Mitigation Strategy
Strengths:
1) Clear understanding and consideration of the range of potential mitigation actions. 2) Good to see the use building codes updates as a key mitigation action across multiple hazards. Consider including land-use zoning changes and other planning-related activities as part of the mitigation strategy in future update. Many of these alternative planningrelated activities are also eligible for federal funding.

Opportunities for Improvement:
1) Connecting mitigation actions to the plan’s goals and objectives. Consider directly identifying the ways in which the individual mitigation actions further progress towards the plan’s goals and objectives. The use of pre-identified metrics would help track progress towards goal attainment and evaluate the effectiveness of mitigation actions. 2) It is strongly encouraged to use ‘problem statements’ in developing mitigation goals, objectives, actions, and/or strategies. Problem statements are succinct summaries of a community’s vulnerabilities to a given hazard and may include the known or suggested causes or contributing factors to vulnerability. These plain language problem statements can then be used to organize and craft plan goals and subsequent objectives, actions, or strategies (for reference, see California Adaptation Planning Guide, 2020, CalOES). 3) Many of the proposed actions aren’t directly related to risk reduction or hazard mitigation, but rather address emergency preparedness and response actions. Although a mitigation action for each high-priority hazard was provided, meeting review criteria, in future updates, please consider the range of actions that will reduce or avoid future losses for each the plan’s identified hazards.

7.1.d
Packet Pg. 431
FEMA Region IX Local Hazard Mitigation Plan Review Tool 13 Element D: Plan Update, Evaluation, and Implementation (Plan Updates Only) Strengths:
1) Excellent use of ‘Table 45: Method and Schedule for Maintaining and Updating Mitigation Plan’ to describe how Diamond Bar intends to maintain the plan and prepare for future updates ahead of the 5-year expiration point.

Opportunities for Improvement:
1) Recommend considering the sources of data available to assess hazards and mitigation actions throughout the 5-year period. Qualitative assessments are useful and can leverage the expertise and experience of city staff, but quantitative sources of data may help identify patterns and trends in hazards and vulnerabilities affecting the planning area. 2) Consider identifying a specific person/position responsible for monitoring plan and mitigation action outcomes. While the City Manager’s office is identified, it often advantageous to appoint a specific person/position to monitor the plan and integrate mitigation actions with existing city resources and planning mechanisms.
