Summary

Denver City Council Governance & Intergovernmental Relations Committee Meeting (Dec 16, 2025)

The Governance & Intergovernmental Relations Committee, chaired by Councilmember Amanda Sawyer, received a briefing from Denver’s Office of Emergency Management (OEM) on low-probability, high-consequence (“catastrophic”) risks, current mitigation work (especially evacuation planning and public alerting), and major operational challenges (transportation, sheltering facilities, staffing, and emergency procurement). The committee then entered executive session to discuss ongoing litigation and returned to adjourn.

Consent Calendar

  • Chair noted there were “a few items on consent” that were not pulled and would move forward (no individual items were described in the transcript).

Discussion Items

  • OEM catastrophic risk overview (Matt, OEM Executive Director)
    • Why OEM is focused on catastrophic risks: OEM emphasized that day-to-day hazards (extreme cold, snowstorms, flooding, cybersecurity) can overshadow low-probability/high-consequence events, despite recent history showing unexpected major events can occur.
    • Key catastrophic hazards highlighted (project descriptions):
      • Wildfire / urban conflagration risk: OEM presented state wildfire “burn probability” mapping and highlighted higher risk in grassland/open space areas near the airport (including Green Valley Ranch, Montbello, parts of Central Park), with particular concern near the Rocky Mountain Arsenal where homes are close to open space.
      • Dam failure inundation (Cherry Creek Dam focus): OEM described Cherry Creek as a key catastrophic-risk focus due to the dam’s age. A combined inundation map (Chatfield + Cherry Creek failure scenario) was shown to illustrate potentially widespread impacts.
      • Hazardous materials release (rail/highway corridors): OEM showed mapping of rail corridors carrying large quantities of hazardous materials (e.g., ammonia, diesel fuel, chlorine) and noted some nuclear waste shipments typically move along the I-25 corridor.
    • Public Safety Power Shutoff (PSPS) coordination (Xcel): OEM described Xcel’s PUC-required PSPS planning after the Marshall Fire as a wildfire mitigation measure (proactive de-energizing during high wind/low humidity). OEM noted daily coordination calls with Xcel and emphasized potential Denver impacts even if shutoff footprints are outside city limits (e.g., critical infrastructure like water/wastewater facilities).
    • Evacuation planning initiative (major mitigation effort):
      • OEM stated Denver lacks a broad, neighborhood-scale evacuation plan (beyond prior event-specific plans like the 2008 DNC downtown plan and existing Cherry Creek flood scenario planning).
      • OEM reported support from the U.S. Army Corps of Engineers and Parsons Engineering for transportation modeling.
      • Draft evacuation plan anticipated early next year, with a tabletop exercise planned for mid-2026.
      • Planning components described: decision-making tradeoffs, egress route identification (surface roads vs. interstates), evacuation methods for people without cars and those unable to evacuate, alert/warning, and traffic control.
    • Alerting & warning improvements:
      • OEM referenced the wireless emergency alert (WEA) test conducted in September (intended to increase public familiarity and encourage people to keep alerts enabled).
      • Outdoor warning sirens: a live test every year in May (and later in Q&A OEM noted moving away from monthly live tests to reduce desensitization).
      • OEM described focus groups with older adults and Spanish-speaking communities to improve message clarity; development of an evacuation area mapping tool; and an MOU with the State of Colorado for backup alerting if OEM/Denver 911 cannot send alerts.
    • Operational challenges flagged by OEM:
      • Transportation capacity: OEM said RTD and DPS buses/drivers are not always available; suggested on-call contract bus service could help.
      • Facilities/shelter capacity: finding enough sheltering facilities is difficult, especially if entire neighborhoods are displaced.
      • Staffing: OEM strongly supported an on-call staffing contract (referencing a contract discussed the prior night through Human Services and HOST) to avoid pulling city staff from essential functions.
      • Emergency procurement: OEM expressed concern that current city processes may not allow rapid contracting for urgent needs (e.g., a demolition contractor within 48 hours after a Surfside-like collapse) while also preserving FEMA reimbursement eligibility.

Public Comments & Testimony

  • No public comment period testimony was reflected in the transcript.

Councilmember Questions & Positions (during discussion)

  • CM Kevin Flynn (District 2)
    • Questioned the accuracy/logic of the state wildfire risk map for irrigated/groomed areas (e.g., Fort Logan/Cemetery, City Park).
    • Expressed constituent concern about Denver park mowing/naturalization practices leaving tall dry weeds near homes, and raised fears about fires set in natural areas; sought advice on wildfire risk mitigation.
    • Stated residents in Lowry are concerned about open space wildfire risk.
  • CM Diana Romero Campbell (District 4)
    • Asked about Cherry Creek Dam risk, whether there is a current evacuation plan, and what Southeast Denver should do.
    • OEM clarified that each high-hazard dam has an Emergency Action Plan (Cherry Creek is managed by the U.S. Army Corps of Engineers and updated annually) and distinguished dam-failure inundation from standard floodplain mapping.
    • Sought reassurance about likelihood; OEM characterized it as very low likelihood but catastrophic consequence.
  • CM Garrett Watson (District 9)
    • Asked about OEM coordination with Community Planning & Development regarding high-density developments adjacent to rail (e.g., River Mile, Ball Arena) given hazardous materials transport.
    • OEM stated there are ongoing interagency conversations (including a quarterly hazard mitigation working group) and noted the difficulty of balancing development/housing needs with hazard risk.
  • CM Paul Kashmann (District 6)
    • Expressed concern that on high wind days, an ordinary structure fire could escalate into broader conflagration, especially where homes are close together.
    • Asked about WEA coverage; OEM estimated above 95% for compatible phones (last 8–10 years) and noted the primary issue is users disabling alerts.
    • Expressed appreciation for OEM’s emergency coordination work.
  • Councilmember (At-Large) Serena Gonzales-Gutierrez (speaker name appears in roll call; questioning in transcript labeled “Councilman Alvidas,” but content is summarized without assuming identity)
    • Raised concerns about rail derailment/hazmat incidents (referencing East Palestine, OH), desensitization to alerts, and timeliness of rail notification.
    • OEM stated rail companies’ legal mandate is to notify the State of Colorado first, with the state then notifying locals, and acknowledged the “cry wolf” challenge in public alerting.

Executive Session

  • Committee entered executive session under DRMC 2-34(a)(3) and (a)(7) to discuss ongoing litigation and privileged legal advice.

Key Outcomes

  • Briefing received from OEM on catastrophic risks and mitigation initiatives.
  • Evacuation planning: OEM expects a draft plan early next year and a tabletop exercise in mid-2026.
  • Alerting strategy: OEM reaffirmed annual WEA testing (September) and annual live siren testing (May), with additional work on message clarity and backup alerting arrangements.
  • Executive session held for litigation/legal advice; meeting adjourned afterward.

Meeting Transcript

Welcome back to this monthly meeting of the Governance and Intergovernmental Relations Committee of Denver City Council. Thanks for joining us for the discussion. The governance and intergovernmental relations committee starts now. Good morning, everyone. It is Tuesday, December 16th. Happy holidays. I'm Amanda Sawyer. I have the honor of representing the residents of District 5 and also chairing this committee. We have a briefing today from our Office of Emergency Management, followed by an executive session. So before we get started, why don't we do a round of introductions, Council First How? Let me start with you. Wonderful. Good morning, Diana Romero Campbell, Southeast Denver District 4. Good morning, Garrett Watson, Flying District 9. Good morning. Paul Cashman, South Denver District 6. Good morning, Serena Gonzalez Cutis, one of your council members at large. Good morning, Kevin Flynn, Southwest Denver's District 2. Alright, thank you. So Matt, you are, are you doing our presentation for us? I believe so. Then come on up to the table. And we can get you all set up. The computer at the end there, you can, it should have your presentation pulled up. So you can just come and sit at the end, introduce yourself, run your slides, and you're good to go. I will say this is really good timing. Along the front range tomorrow, Wednesday the 17th. Okay, thank you. And so what we're going to talk about today is catastrophic risk overview with OEM, which is really interesting. Thanks for being here. Uh happy to be here. Uh nice to see all of you. I think I know some of you more than others. I suspect I am probably the ED you see the least across city agencies or one of them. Uh maybe that's for good reason. Um I was asked uh to come and give an overview and a presentation for you all, which I actually really appreciate because we don't often get on the radar, and there are some things that uh tend to get lost in the weeds, but I think it's important for all of you to know. So I want to run through some of those today. Um, so why are we thinking about catastrophic risks? And a lot of that comes down to that we focus a lot on the day-to-day for good reason and the concerns that we have of extreme cold weather and snowstorms and even things like uh flooding, cybersecurity, all of those things are very critical, but there are some low probability, high consequence hazards that we need to consider, and they tend to get pushed aside, and we tend to think that those things are just not going to happen. And if I were to ask any of you in 2019 if we'd have the largest pandemic in a hundred years, the greatest social unrest since the late 1960s, and the greatest flow of migrant newcomers into Denver that maybe we have seen 44,000 over a two-year period, you probably would not have believed me, and yet all of those things occurred. And so I think it's important that we talk about some other potentialities. We have seen specifically urban conflagration, so a large fire that takes off in an urban area, often wildfire induced, dam failure, and hazardous materials releases. These are all not only possible, but would be severe if not catastrophic. And some recent examples that were all over the news in the last few years that you may remember. Um, so we want to just highlight these. One of the things also that I'll I'll point to is uh some of you may remember um Councilmember Orteger, former council member Ortega. Uh, before her uh tenure ended, one of the things that she pushed was a rail hazmat bill. And it commissioned a study that was done through some other city agencies, and there were some recommendations in there, and many of those recommendations were extremely costly on the order of hundreds of millions, even into the billions of dollars to try to implement. And one of the things that I said when this was up was that not my decision whether to make those investments, they don't seem economically feasible. However, there are other things we can do that are much more cost effective.
