Description of Project: During the incident period of May 4 – June 16, 2015, heavy rainfall produced heavy flows and flash flooding causing damage to this site in El Paso County in multiple storm events.  High velocity flood waters and massive volumes of Fountain Creek washed away and destroyed multiple areas on two sites of the Hanson Trailhead, in the general area of the pedestrian bridge, Fountain Creek embankment to the north of the bridge, and pedestrian trail.  Flash flooding caused erosion/scouring of the embankment, a large loss of embankment soil material, loss of riprap embankment stabilization material, loss of a section of multi-use trail, large woody debris deposition, damage to grouted riprap embankment protection, damage to soil cement trail base, and damage to the pedestrian bridge abutments.  Multiple flash flood events during the incident period exacerbated the damage.  This project consisted of excavating point bar; restoring approximately 600 feet of Fountain Creek; constructing bioengineered bank stabilization; constructing bioengineered bendway weirs and J-hooks; repairing damaged trail; constructing new trail; relocating salvaged pedestrian bridge and constructing new pedestrian bridge; seeding disturbed areas; constructing high flow channel. Tezak Heavy Equipment also provided expertise experience in the design coordination to reach the final 100% plans with the focus on access & staging; water control and dewatering; erosion control; material sourcing and availability
