The Problem

From golf-ball-sized hail to flash floods, Lakewood, CO, has already faced millions in damage from climate hazards over the past decade. Its climate is on track to become hotter, drier in the summer, and more unpredictable. The City of Lakewood asked SSG to help it better understand future risks so it could prepare and increase the community’s resilience to climate hazards.

The Problem

What risks do climate hazards pose to Lakewood’s people, infrastructure, and economy?

6

billion-dollar natural disasters in Colorado in 2024

185

deaths from heat waves, severe storms, and tornados in Colorado in 2024

The Solution

SSG analyzed climate projections, local data, and community input to assess risks based on three factors: how likely a hazard is to occur, how vulnerable the community is to the hazard, and what the consequences would be if it happens. The resulting Climate Hazard and Social Vulnerability Study examined 10 hazards and proposed 61 actions to help Lakewood improve its resilience to them. The study focused on the five hazards Lakewood is most vulnerable to: hailstorms, extreme heat, extreme cold, flooding, and wildfires.

The Outcome

The Climate Hazard and Social Vulnerability Study highlighted:

10-30

additional days over 95°F annually by 2080

$84.5M

in potential damages from an extreme flood by 2070

180k

more people exposed to dangerous temperatures during heat waves in 2070

$170M

real estate value at high or extreme risk of wildfires by 2050

*in a high-emissions scenario compared to current conditions.

Outcome

Key Takeaways

Vulnerability varies

The Climate Hazard and Social Vulnerability Study combined a spatial equity index with data on local infrastructure climate projections to understand which demographic groups would struggle most to recover from climate hazards and where to find them. The resulting analysis is a resource for the City to plan interventions that support those at greatest risk.

Location matters

The study includes spatial assessments of potential climate hazards created with ScenaAdaptation. The projections highlighted which neighbourhoods will have the warmest temperatures during heat waves, where floods will hit infrastructure the hardest, and areas most exposed to wildfire—as well as how these risks shift between 2023 and 2050. The insights enable strategic planning down to the neighborhood level.

Community insight is key

Residents, city staff, local organizations, businesses, and experts weighed in through two working groups, a community survey, and focus groups. Their input provided insight on how people, infrastructure, and the economy are affected by climate hazards, highlighting challenges and strengths that aren’t captured by climate projections. The community also shaped the study by brainstorming and critiquing potential actions.
