The 2,811 <br />foot concrete trapezoidal storm water/flood control channel is comprised <br />of side to side 10ft (W) x 14ft (L) x 0.33ft (D) unreinforced side concrete <br />panels connected to a concrete floor. High velocity water intruded <br />behind the angled side concrete panels intermittently along the north <br />and south sides of the channel along approximately 800 feet of this <br />engineered structure. As a result of this water Intrusion, these panels <br />were displaced (settled or expanded) causing cracks and a non -linear <br />smooth flowing surface. <br />Specifically, the damages were: <br />Site 1: Flood Channel start GPS 33.741666-117.92222 to end GPS <br />33.740380-117.928653 <br />1. 73 - Unreinforced concrete panels damaged that measure <br />approximately 14ft x 10ft x 0.333ft. <br />14ft x 10ft = 140sf x 73 = 10,220sf /9=1135.5sy <br />2. Earthenbase material displaced under 73 damaged concrete panels <br />measuring approximately 14ft (L) <br />x 10ft (W) x 0.33ft (D)127 = 1.7cy x 73 panels = 125cy <br />Project Notes: <br />1.
