Provo Public Works details debris‑flow response after Buckley Draw fire, outlines channel extension and short‑term protections

PROVO, Utah — Provo City Public Works officials on Wednesday presented findings from recent debris flows connected to a late‑summer wildfire above Buckley Draw and described near‑term and permanent mitigation the city and a private developer are pursuing.

The presentation by Jacob O’Brien, Provo Public Works stormwater engineer, and Tim Thompson of GeoStrata said nearly the entire Buckley Draw watershed burned this summer and an intense storm — about 0.7–0.8 inches of rain in roughly 30 minutes — produced a debris flow that carried far more sediment and water than earlier events. “That flow would not have occurred if it were not for the fire,” O’Brien said.

The meeting mattered to residents because the debris flow sent mud and rock into a developed area that includes businesses, two churches and homes along Slate Canyon and Nevada Avenue, and because construction grading on an adjacent development altered how the flow moved. Officials emphasized that temporary and permanent measures are intended to reduce risk but cannot eliminate it entirely.

O’Brien and Thompson outlined the basin and channel history: the Buckley Draw watershed is roughly 500 acres; federal work after a 2002 fire installed a deflection berm, a conveyance channel and temporary silt fences; about 450 acres (roughly 90 percent of the watershed) burned this summer; and modeling indicates this year’s event carried…
