Background on Mitigation Planning in Jefferson County

Section titled “Background on Mitigation Planning in Jefferson County”

The primary purpose of the Jefferson County Hazard Mitigation Plan (HMP) update is to reduce or eliminate long-term risk to people and property from natural and human-caused hazards and their effects on the Jefferson County planning area. Recognizing the importance of hazard mitigation planning, Jefferson County and the cities of Arvada, Lakewood and Wheat Ridge participated in the 2003 Denver Regional Council of Governments (DRCOG). In order to develop a more specific risk assessment, goals, and mitigation projects, the County and the jurisdictions noted previously, developed their own Jefferson County specific multi-jurisdictional plan in 2009-2010 with an additional ten jurisdictions participating in the planning process. In 2015-2016 the plan underwent a comprehensive five-year update as required by the DMA.

The Hazard Mitigation Plan (HMP) underwent a comprehensive update in 2021. The planning process followed during the update was similar to what was used in the original plan development. This planning process utilized the input from a multi-jurisdictional Hazard Mitigation Planning Committee (HMPC). A consultant, Wood Environment & Infrastructure Solutions, Inc (Wood) was hired to assist with the update in 2021. The plan update process is described further in this section and documented in Appendix C.

Jefferson County and its communities has been an integral constituent in nurturing partnerships across boundaries for decades. This proactive approach established the County as a leader to the Front Range communities for hazard mitigation and overall emergency management program planning. This plan builds from the accumulated efforts of previous planning mechanisms that clearly align with the planning regulations set forth by the Disaster Mitigation Act of 2000 (DMA).

This HMP update involved a comprehensive review and update of each section of the 2016 plan and includes an assessment of the progress of the participating communities in evaluating, monitoring and implementing the mitigation strategy outlined in the initial plan. Only the information and data still valid from the previous plan was carried forward as applicable into this HMP update.

One significant change to the 2021 plan update process was the inclusion of five new participating jurisdictions, each listed below under Section Local Government Participation. Three jurisdictions (Lakeside, Mountain View, and Pleasant View Metropolitan District) that participated in 2016 chose not to patriciate in the 2021 plan update due to other priorities and limited resources.

Wood developed a summary of each section in the plan and guided the HMPC through the elements that needed updating during the kickoff meeting in December 2020. This included analyzing each section using FEMA’s local plan update guidance (2013) as well as guidance from the National Flood Insurance (NFIP) Community Rating System (CRS), to ensure that the plan met the latest requirements. The HMPC and Wood determined that nearly every section of the plan would need revision to align the plan with the latest FEMA planning guidance and requirements. A summary of the changes in this plan update is highlighted in the table below.

The DMA planning regulations and guidance requires each local government seeking FEMA approval of its mitigation plan must participate in a planning process effort in the following ways:

Participate in the process as part of the Hazard Mitigation Planning Committee (HMPC),

Differentiate geographical locations or jurisdictions within the planning area where the hazard risk differs from that facing the entire planning area,

Identify mitigation projects, specific to each jurisdictional entity, to be eligible for funding, and

Engage the governing body for formal adoption of the plan. For the Jefferson County HMPC, “participation” meant:

Attending and participating in the HMPC meetings,

Providing available data requested of the HMPC,

Reviewing and providing comments on the plan drafts,

Collecting and providing other requested data (as available);

Managing administrative details;

Making decisions on plan process and content;

Identifying mitigation actions for the plan;

Reviewing and providing comments on plan drafts; including annexes

Informing the public, local officials, and other interested parties about the planning process, and providing opportunity for them to comment on the plan;

Coordinating, and participating in the public input process; and

Coordinating the formal adoption of the plan by the governing boards.

The County and all jurisdictions with annexes to this plan seeking FEMA approval met all of these participation requirements. In most cases, one or more representatives for each jurisdiction attended the HMPC meetings described in Appendix B and also brought together a local planning team to help collect data, identify mitigation actions and implementation strategies, and review and provide data on plan drafts. Appendix C provides additional information and documentation of the planning process.

Wood established the planning process for Jefferson County’s plan using DMA planning requirements and FEMA’s associated guidance. This guidance is structured around a four-phase process:

Organize Resources

Assess Risks

Develop the Mitigation Plan

Implement the Plan and Monitor Progress

Into this four-phase process, Wood integrated a more detailed 10-step planning process used for FEMA’s Community Rating System (CRS) and Flood Mitigation Assistance programs. Thus, the modified 10-step process used for this plan meets the funding eligibility requirements of the Hazard Mitigation Assistance grants (including Hazard Mitigation Grant Program, Building Resilient Infrastructure and Communities grant, High Hazard Potential Dams grant, and Flood Mitigation Assistance grant), Community Rating System, and the flood control projects authorized by the U.S. Army Corps of Engineers (USACE).

Jefferson County, the City of Arvada, Golden, Lakewood, Wheat Ridge, and the Town of Morrison participate in the CRS, and thus could potentially earn planning credits from the development of this plan. shows how the modified 10-step process fits into FEMA’s four-phase process, and how these elements correspond to the tasks in the FEMA “Mitigation Planning Handbook.”

Planning Step 1: Organize the Planning Effort

Section titled “Planning Step 1: Organize the Planning Effort”

The Jefferson County Sheriff’s Office of Emergency Management (OEM) worked to establish the framework and organization for the development of the plan update. This process began with the FEMA planning grant application in 2018. Participating jurisdictions indicated their commitment to participate as evidenced by executing a letter of commitment as a component of the FEMA planning grant. Award of the grant in October 2019 allowed the planning consultant, Wood, to be procured through a competitive bid process.

Wood worked with the County to get organized for the plan update. Organizational efforts were initiated with the County and participating jurisdictions in December 2020 to inform and educate the plan participants of the purpose and need for updating the countywide hazard mitigation plan. An initial meeting between Wood and County OEM was held to discuss the organizational aspects of this plan update process. Invitations to the kickoff meeting for this plan update were extended to key County departments, the eight incorporated communities, and representatives from special districts for the County and municipalities, as well as to other federal, state, and local stakeholders that might have an interest in participating in the planning process. Representatives from participating jurisdictions and HMPC members to the 2016 plan were used as a starting point for the invite list, with additional invitations extended as appropriate throughout the planning process. The list of initial invitees is included in Appendix C.

Key stakeholders were identified including representatives from the various county departments, each municipal jurisdiction, and other state and local government agencies. An email was sent from County OEM to describe the upcoming mitigation planning efforts and invite potential members to participate in a kickoff meeting where the HMPC would be formally organized. Suggested representation from each municipality included city/town manager, emergency manager, floodplain manager, public works/engineering, building department and fire department/district representative. Table 3-3 lists the HMPC participants and their respective jurisdiction in the development of the plan. Other stakeholders that participated in the planning process are discussed under Planning Step 3: Coordinate with Other Departments and Agencies.

In the 2020-2021 plan update, the following communities and jurisdictions participated in the process.

Jefferson County

City of Arvada

City of Edgewater

City of Golden

City of Lakewood

City of Wheat Ridge

Town of Morrison

Denver Water

Arvada Fire Protection District (New)

Elk Creek Fire Protection District (New)

North Fork Fire Protection District

West Metro Fire Protection District

The Town of Bow Mar, Town of Lakeside, Town of Mountain View, and Pleasant View Metropolitan District elected not to participate in the Jefferson County multi-jurisdictional planning process. The City of Westminster has its own hazard mitigation plan and did not participate in the Jefferson County multi- jurisdictional planning process since the City lies within both Jefferson and Adams County. The Town of Superior has a portion of their Town in Jefferson County but opted to participate in the Boulder County Hazard Mitigation Plan. The City of Littleton also has a small area in Jefferson County but participated in the Arapahoe County Multi-Hazard Mitigation Plan update.

The Disaster Mitigation Act requires that each jurisdiction participate in the planning process and officially adopt the multi-jurisdictional hazard mitigation plan. A planning committee was created that includes representatives from each participating jurisdiction, departments of the County, and other local, state, and federal organizations responsible for making decisions in the plan and agreeing upon the final contents. Kickoff meeting attendees discussed potential participants and made decisions about additional stakeholders to invite to participate on the HMPC.

The HMPC contributed to this planning process by:

Providing facilities for meetings,

Attending meetings,

Collecting data,

Managing administrative details,

Making decisions on plan process and content,

Submitting mitigation action implementation worksheets,

Reviewing and editing drafts, and

Coordinating and assisting with public involvement and plan adoptions

The HMPC was comprised of two groups, a Steering Committee that led the planning and decision- making efforts throughout the planning process, and a Working Group comprised of additional local staff that provided information to the Steering Committee. The Steering Committee is the group responsible for the 10-Step CRS planning process outlined in the 2017 CRS Coordinator’s Manual. The Working Group supported the overall HMP process by providing information and data to the CRS Steering Committee for consideration and decision-making. Membership and participation in both the Steering Committee and Working Group are listed in Appendix B.

The HMPC communicated during the planning process with a combination of meetings, phone interviews, and email correspondence. All meetings were held virtually due to social distancing requirements associated with the ongoing COVID-19 pandemic. A folder on Google Drive was hosted by Wood and a SharePoint site hosted by the County were both used to share drafts of the plan and its annexes for jurisdictional review and input. Three planning meetings with the Planning Team were held during the plan’s development between December 2020 and February 2021. The meeting schedule and topics are listed in the following table; all 10 planning process steps were covered in these three meetings.

Agendas, meeting summaries, and attendance records for each of the meetings are included in Appendix C.

On December 7, 2020, the HMPC convened virtually with 85 people participating, to kick off the plan update process. Wood presented information on the scope and purpose of the plan update, participation requirements of HMPC members, and the proposed project work plan and schedule. Plans for public involvement (Step 2) and coordination with other agencies and departments (Step 3) were discussed.

Wood also introduced the hazard identification requirements and data. The HMPC discussed past events and impacts and future probability for each of the hazards required by FEMA for consideration in a local hazard mitigation plan. The HMPC made two revisions to the hazards list from the 2016 plan, adding Pandemic and Cyber Attacks. Each jurisdiction provided updates to the plan and their respective annexes via a plan update guide and mitigation action tracker.

HMPC Meeting #2 – Risk Assessment Update
Section titled “HMPC Meeting #2 – Risk Assessment Update”

On January 11, 2021, the HMPC convened virtually to review and discuss the results of the risk and vulnerability assessment update (Steps 4 and 5). There were 81 members of the HMPC and stakeholders were present for the discussion. Wood presented the results the risk assessment for natural and human- caused hazards. The group went through each hazard together and discussed the results as well as shared any local insight to inform the HIRA update. Refer to the meeting summary in Appendix C for notes related to each hazard discussed. Some of this discussion was also related to the reviewing and updating the 2015-2016 goals.

HMPC Meeting #3 – Mitigation Strategy and Goals Update
Section titled “HMPC Meeting #3 – Mitigation Strategy and Goals Update”

The HMPC convened virtually on February 11, 2021 with 69 people participating to update the plan’s mitigation strategy. The group finalized the plan’s goals and objectives (Step 6) and discussed the criteria for mitigation action selection and prioritization using a worksheet provided by Wood. The group reviewed each possible new mitigation action and additional details were provided by the Planning Team (Step 7). The meeting ended with a review of the next steps and planning process schedule. Wood provided the Planning Team with a link to an online form to submit new mitigation actions. During the Planning Team review of the full plan, each member was provided a handout on prioritizing new mitigation actions and asked to focus on prioritizing each new mitigation action for their jurisdiction.

Involving the public assures support from the community at large and is a part of the planning process. At the kickoff meeting, strategies to involve the public were discussed for soliciting public input on the mitigation plan and developed an outreach strategy by consensus. The fact that the process was conducted during the COVID-19 pandemic, with attendant restrictions on public gatherings, made it difficult to use many traditional outreach methods such as in-person public gatherings or discussions at other forums. The HMPC adapted by leveraging virtual meetings and other online messaging, which in

many cases resulted in greater public attendance and involvement than more traditional face-to-face meetings. An online public survey was developed by Wood and shared with the Planning Team to share through their respective public information channels. In addition to the online public survey, two virtual public workshops were held in January and June 2021.

These outreach efforts are summarized in and discussed below.

During the plan update’s initial drafting stage, an online public survey was used to gather public input to the Planning Team. The survey provided an opportunity for public input during the planning process, prior to finalization of the plan update. The survey gathered public feedback on concerns about hazards and input on mitigation strategies to reduce their impacts. The survey was released on January 6, 2021 and closed on January 31, 2021. The Planning Team provided links to the public survey by distributing it using social media, email, and posting the link on websites. A link to the survey was also posted on some of the participating jurisdictions’ websites as well as through social media posts; screenshots from both can be found in Appendix C. A total of 953 people filled out the survey online. Results showed that the public perceives the most significant hazards to be wildfire, drought, hailstorm and pandemic/public health.

Question 4 of the survey asked the public’s opinion on what mitigation actions that should have the highest priority in the updated hazard mitigation plan; wildfire fuels treatment projects, forest health/watershed protection, water conservation, evacuation route development and public health incident preparedness were cited as the most popular mitigation actions. This information was shared with the Planning Team during the update of the mitigation strategy to consider when evaluating hazard rankings

and as a source of potential mitigation ideas. A summary of all the survey data and documentation of the public feedback can be found in Appendix D.

Section titled “Figure 3-1 Hazard Mitigation Planning Survey Link on Jefferson County Twitter”

Two online public workshops were held during the planning process to inform the public, receive input to integrate into the plan update, and keep the public updated on the progress being made in the planning process. Both workshops were held virtually as webinars due to social distancing requirements associated with the ongoing COVID-19 pandemic.

The workshop took place on January 14, 2021 through Zoom. The workshop introduced the public to the hazard mitigation planning process for the County’s Plan Update and answered any questions and gather public input to be integrated into the plan update. In addition, it was an opportunity to help staff identify risks, hazards and vulnerabilities from the public’s perspective. In total 26 individuals participated in the virtual workshop. Members of the public were able to submit comments verbally or via the chat function. The Planning Team received four comments from the meeting that helped to inform the Planning Team on the public initial thoughts on hazard mitigation and hazards in their community. A recording of the meeting was subsequently posted on Jefferson County’s YouTube channel, where it has an additional 128 views as of July 1st, 2021.

The second virtual public workshop was held on June 8, 2021, again conducted via Zoom. Eight members of the public attended this meeting, which gave an update on the planning process, reviewed the results of the public survey, and introduced the updated Plan. The purpose, contents, and key components of the updated plan were described, and participants were encouraged to review and comment on the draft plan. A recording of the meeting was subsequently posted on Jefferson County’s YouTube channel, where it has an additional 10views as of July 1st, 2021.

Section titled “Figure 3-2 Public Meeting #1 Screenshot, January 14, 2021”

Following the HMPC draft review a public review draft of the plan was prepared. The public was given an opportunity to provide input on this draft of the complete plan prior to its submittal to the State and FEMA. A virtual public engagement room was created for people to learn about the plan, download and review copies of the draft plan and annexes, and upload comments and feedback using an online survey tool.

The draft plan and annexes were also made available on the County’s emergency management web page from June 7th–25th, 2021. The comment period was advertised extensively through the jurisdictions’ websites and social media accounts. The City of Arvada also made the plan available through their Speak Up Arvada platform. A total of eleven comments were received, which are included in Appendix B. The comments were reviewed with the Planning Team and used to inform revisions to the draft Plan.

Planning Step 3: Coordinate with Other Departments and Agencies

There are numerous organizations whose goals and interests interface with hazard mitigation in Jefferson County. Coordination with these organizations and other community planning efforts is vital to the success of this plan update. The Jefferson County Office of Emergency Management invited other local, state, and federal departments and agencies to the kickoff meeting to learn about the hazard mitigation planning initiative. Many of the agencies participated throughout the planning process in meetings described in Step 1: Organize the Planning Effort.

Stakeholders include local and regional agencies involved in hazard mitigation activities or those beyond the County and local government that have the authority to regulate development. Stakeholders could participate in various ways, either by contributing input at HMPC meetings, being aware of planning activities through an email group, providing information to support the effort, or reviewing and commenting on the draft plan. Based on their involvement in other hazard mitigation planning efforts, and status in the County, representatives from the following agencies and organizations were invited to participate as stakeholders in the process; an asterisk indicates they participated in HMPC meetings:

  • Participated in HMPC meetings

The majority of the listed stakeholders were invited to participate through an email from the Jefferson County Emergency Manager on November 17, 2020, which included an invitation to the kickoff meeting. A complete list of agencies and persons invited to the kick off meeting, plus the invitation itself, can be referenced in Appendices B & C. As part of the public review and comment period for the draft plan, key agencies were again specifically solicited to provide any final input to the draft plan document. This input was solicited both through membership on the HMPC and by direct emails to key groups and associations to review and comment on the plan. As part of this targeted outreach, these key stakeholders were also specifically invited to attend the HMPC and public meeting to discuss any outstanding issues and to provide input on the draft document and final mitigation strategies.

Coordination with key agencies, organizations, and advisory groups throughout the planning process allowed the HMPC to review common problems, development policies, and mitigation strategies as well as identifying any conflicts or inconsistencies with regional mitigation policies, plans, programs and regulations. Phone calls and emails were used during plan development to directly coordinate with key individuals representing other regional programs.

The HMPC also used technical data, reports, and studies from the following agencies and groups, just to name a few:

Colorado Water Conservation Board

Colorado Geological Survey

FEMA

Mile High Flood District

Appendix F References provides a detailed list of references used in the preparation of this plan update. Specific references relied on in the development of this plan are also sourced throughout the document as appropriate.

Several opportunities were provided for the groups listed above to participate in the planning process. At the beginning of the planning process, invitations were extended to these groups to actively participate on the HMPC. Specific participants from these groups are detailed in Appendix B. Others assisted in the process by providing data directly as requested or through data contained on their websites or as maintained by their offices. Further, as part of the public outreach process, all groups were invited to attend the public meetings and to review and comment on the plan prior to submittal to DHSEM and FEMA. In addition, as part of the review of the draft plan, key agency stakeholders were contacted, and their comments specifically solicited.

This process was accomplished as part of planning tasks two and three in the FEMA Local Mitigation Planning Handbook.

Incorporation of Existing Plans and Other Information
Section titled “Incorporation of Existing Plans and Other Information”

The coordination and synchronization with other community planning mechanisms and efforts are vital to the success of this plan. To have a thorough evaluation of hazard mitigation practices already in place, appropriate planning procedures should also involve identifying and reviewing existing plans, policies, regulations, codes, tools, and other actions are designed to reduce a community’s risk and vulnerability from natural hazards. Jefferson County uses a variety of mechanisms to guide growth and development. Integrating existing planning efforts, mitigation policies, and action strategies into this plan establishes a credible, comprehensive document that weaves the common threads of a community’s values together. The development of this plan involved a comprehensive review of existing plans, studies, reports, and initiatives from Jefferson County and each participating municipality.

The following table includes a comprehensive list of the documents reviewed and how they informed the HMP update.

2016 Mitigation Plan Inclusion in Other Planning Mechanisms

Section titled “2016 Mitigation Plan Inclusion in Other Planning Mechanisms”

The 2016 HMP was integrated into other planning mechanisms in the County. The risk assessment portion of the 2016 plan was integrated into the other planning mechanisms listed in The table lists the jurisdiction and what planning mechanism the 2016 Plan was integrated into. In some cases, communities have deferred this for future planning mechanisms, as discussed in the Section Plan Implementation and Maintenance.

Wood led the HMPC in an effort to identify and document all the hazards that have, or could, impact the planning area, including documenting recent drought, flood, wildfire and winter storm events. Data collection worksheets were used in this effort to aid in determining hazards and vulnerabilities and where risk varies across the planning area. The profile of each of these hazards was then developed and updated for 2021 with information from the HMPC and additional sources. Web resources, existing reports and plans, and existing GIS layers were used to compile information about past hazard events and determine the location, previous occurrences, probability of future occurrences, and magnitude/severity of each hazard. Geographic information systems (GIS) were used to display, analyze, and quantify hazards and vulnerabilities. A more detailed description of the hazard identification and risk assessment process and the results are included in Section Risk Assessment.

After updating the profiles of the hazards that could affect the County, the HMPC collected information to describe the likely impacts of future hazard events on the participating jurisdictions. This step included two parts: a vulnerability assessment and a capability assessment.

Vulnerability Assessment—Participating jurisdictions updated their assets at risk to natural hazards— overall and in identified hazard areas. These assets included the total number and value of structures; critical facilities and infrastructure; natural, historic, and cultural assets; and economic assets. The HMPC also analyzed development trends in hazard areas. The DFIRM was used to refine the estimated flood losses during the update, where available for the NFIP participating communities. The results of the vulnerability assessment are included in Section Risk Assessment.

Capability Assessment— The HMPC also conducted a capability assessment update to review and document the planning area’s current capabilities to mitigate risk and vulnerability from natural hazards. By collecting information about existing government programs, policies, regulations, ordinances, and emergency plans, the HMPC can assess those activities and measures already in place that contribute to mitigating some of the risks and vulnerabilities identified. This information for is included in Section and in the respective jurisdictional annexes.

Wood provided the draft risk assessment to the HMPC in March 2021 for review and comment. Results of the risk assessment were presented and comments discussed at the second meeting of the HMPC.

Wood facilitated a discussion session with the HMPC to review the 2016 plan’s goals and objectives. The HMPC discussed definitions and examples of goals, objectives, and actions and considered the goals of

the state hazard mitigation plan and other relevant local plans when reviewing and revising the goals and objectives. The resulting updated goals and objectives are presented in Section Mitigation Strategy.

Planning Step 7: Review Possible Activities

Section titled “Planning Step 7: Review Possible Activities”

Wood facilitated a discussion at an HMPC meeting to review the alternatives for mitigating hazards. This included a brainstorming session with the HMPC to identify a comprehensive range of mitigation actions for each identified hazard, and a method of selecting and defending recommended mitigation actions using a series of selection criteria. More specifics on the process and the results of this collaborative process are captured in Section Mitigation Strategy.

Based on input from the HMPC regarding the draft risk assessment and the goals and activities identified in Planning Steps 6 and 7, Wood produced a complete first draft of the plan. This complete draft was delivered electronically for HMPC review and comment. HMPC and agency comments were integrated into the second draft, which was advertised and distributed to collect public input and comments. Other agencies were invited to comment on this draft as well. Wood integrated comments and issues from the public, as appropriate, along with additional internal review comments and produced a final draft for the Colorado Division of Homeland Security and Emergency Management (DHSEM) and FEMA Region VIII to review and approve, contingent upon final adoption by the governing boards of each participating jurisdiction.

Phase 4: Implement the Plan and Monitor Progress

Section titled “Phase 4: Implement the Plan and Monitor Progress”

In order to secure buy-in and officially implement the plan, the plan was re-adopted by the governing boards of each participating jurisdiction on the dates included in the adoption resolutions in Appendix A Plan Adoption.

Planning Step 10: Implement, Evaluate, and Revise the Plan

Section titled “Planning Step 10: Implement, Evaluate, and Revise the Plan”

The true worth of any mitigation plan is in the effectiveness of its implementation. Up to this point in the planning process, all of the HMPC’s efforts have been directed at researching data, coordinating input from participating entities, and developing appropriate mitigation actions. Each recommended action includes key descriptors, such as a lead manager and possible funding sources, to help initiate implementation. An overall implementation strategy is described in Section Plan Implementation and Maintenance.

Finally, there are numerous organizations within the Jefferson County planning area whose goals and interests interface with hazard mitigation. Coordination with these other planning efforts, as addressed in Planning Step 3, is vital to the ongoing success of this plan and mitigation in Jefferson County and is addressed further in Section A plan update and maintenance schedule and a strategy for continued public involvement are also included in Section

Implementation and Maintenance Process: 2016 Plan
Section titled “Implementation and Maintenance Process: 2016 Plan”

The 2016 Hazard Mitigation Plan included a process for implementation and maintenance which was generally followed, with some variation. Implementation of the plan including the status of mitigation actions is captured in Section and the jurisdictional annexes. In general, the County and participating jurisdictions have made good progress in the implementation of the plan. Successes of note are detailed in Section As a result of revisiting the implementation and maintenance section some modifications were made including:

Changed annual review from October to January.
