CONCEPT WZ-0178

FLOOD ESCAPE PLATFORM
Flash floods can turn narrow canyon passages into deadly traps within minutes, leaving hikers with no way to reach higher ground. WZ-0170 proposes installing small, permanent escape platforms anchored directly to canyon walls at strategic locations throughout the Grand Canyon. Elevated above anticipated floodwaters and debris, these minimally invasive structures would provide immediate refuge where natural escape routes are limited or nonexistent. The concept is simple: provide a place to escape when there is nowhere else to go.

ESTIMATED EXPENSE
The estimated cost of each flood escape platform is $25,000–$50,000, with a preliminary planning estimate of $35,000 per installation. This includes a compact metal platform, safety railings, a permanently accessible ladder, independent rock anchoring systems, fabrication, transportation, and installation.

Standardizing the platform design could reduce fabrication and installation costs across multiple locations. Actual costs would vary depending on accessibility, terrain, and installation requirements.

At an estimated $35,000 per platform, an initial deployment of 10 platforms would cost approximately $350,000, excluding program-wide studies, maintenance, and other supporting expenses.
