Harrison Evacuation Planning Open House Analysis

Evacuation Planning Open House – What Was Said, What It Means, and What’s Missing

Event: Harrison Hot Springs Emergency Preparedness / Evacuation Planning Open House
Presenter: Paul Edmunds, Red Dragon Consulting

Key Statements from the Presenter (Verbatim-Based Summary)

1) Planning Zones and Guidance Documents

The consultant stated they developed evacuation planning zones and a guidance toolkit for the Village Emergency Operations Centre (EOC), not engineered infrastructure or road construction.

“All what we’ve produced is to provide guidance for the village…” (≈4:25–4:39)

2) Population and Traffic Modeling Inputs

They used multiple data sources and added uncertainty buffers:

• 2021 census population (~1,950 residents)

• Hotels, Airbnbs, park units, civic addresses

• Tourism data

• Traffic modeling

• ±20% uncertainty factor for fluctuating population

“We’ve estimated there could be another 3,500 people staying within the village…” (≈33:14–33:40)

3) What the “Time to Evacuate” Actually Means

The 11–16 hour figure is for a strategic, planned evacuation, not a sudden emergency evacuation.

“This is for a strategic evacuation… not the fire department tapping your door to say get out.” (≈34:04–34:12)

The estimate includes:

• Detection / notification delay (“the phone call comes in”)

• EOC staff mobilization

• Door‑knocking operations

• Traffic control setup

• Physical evacuation

• Plus an additional 2‑hour provincial preparedness buffer

“That’s that 11 to 16 hours… plus another two hours.” (≈34:04–34:44)

4) Worst-Case Framing and Real-World Example

The consultant emphasized these are worst-case planning scenarios, noting real evacuations can be faster due to early self-evacuation.

“In real terms that was five six hours because… 20% of people leaving before they receive the door knock.” (≈34:52–35:17)

5) Reliance on a Single Highway

The presenter confirmed Harrison has one primary evacuation highway (Hwy 9) and evacuation would mainly be south.

“You only have one highway… your main evacuation is to go south.” (≈21:49–22:18)

Cross-mountain routes were described as not viable due to terrain constraints.

“There is no viable routes from your village across the mountain…” (≈26:38–26:44)

Key Takeaways

1) “11–16 Hours” Is an Operations Timeline, Not Drive Time

The estimate includes:

• Notification lag

• Staff mobilization

• Door‑knocking logistics

• Traffic control setup

• Physical movement out

• A policy-based 2‑hour preparation buffer

It represents the time to execute an orderly, managed evacuation.

2) Even With Context, the Timeline Is Concerning

Many hazards listed by the consultant can occur rapidly:

• Wildfire wind shifts

• Slope failure / landslides

• Flooding

Rapid-onset events may not provide 11–16 hours of warning.

The model only works if:

• There is early warning time

• Hwy 9 remains open and functional

3) Harrison’s Evacuation Resilience Depends on One Road

The plan assumes:

• Hwy 9 remains open

• No crash, slide, or floodwater blockage

• Traffic control functions effectively

• Public compliance and early self-evacuation occur

This is a structural vulnerability.

4) Tourism Is a Major Risk Multiplier

The consultant modeled:

• ~1,950 permanent residents

• Up to ~3,500 additional seasonal visitors

This confirms Harrison’s evacuation demand can more than double during peak season.

5) The Model Is a Resourcing Tool (Valid Purpose)

The consultant explained the intent is to ensure enough personnel and resources are deployed if evacuation timelines are long.

“If we have four hours… which means that we’re under resourced.” (≈36:08–36:27)

What’s Missing (Information the Village Should Publish)

Critical Modeling Assumptions

• Peak vs off‑season population assumptions

• Vehicle ownership and car occupancy rates

• Compliance and self‑evacuation rates

Road Capacity Metrics

• Vehicles/hour capacity for Hwy 9

• Choke point modeling (intersections, bridges)

Blocking Scenarios

• Partial or full Hwy 9 blockage (collision, landslide, floodwater)

• Contingency routes or transport alternatives

Minimum Warning Time Required

• How much advance notice is required for the 11–16 hour plan to work

Special Population Planning

• Seniors and mobility-impaired transport capacity

• Door‑knocking staffing and timelines

Evacuation Trigger Thresholds

• What engineering or environmental thresholds trigger Alert vs Order

Bottom Line

The evacuation planning study acknowledges Harrison’s constraints: a single highway, seasonal population surge, and extended evacuation timelines. While the 11–16 hour figure reflects worst-case strategic planning and includes operational delays, it highlights a critical dependency on early warning and Hwy 9 remaining open. For rapid-onset hazards, the available evacuation window may be significantly shorter.
