Loop 303 Outfall Channel
WOODPATEL prepared the design of this downstream-most portion of the regional drainage system for the Loop 303 freeway corridor. The project is funded by the District and designed in coordination with ADOT, MCDOT, and Goodyear. The upstream end of the system begins north of Van Buren Street and discharges at the north bank of the Gila River, which equates to 4.5 miles. The project included: open channels, box culverts, storm drains, landscaping, and aesthetic treatments. The complexity of the design addresses crossings of the Union Pacific Railroad, Kinder Morgan petroleum line, the Palo Verde Nuclear Generating Station 96-inch cooling waterline, fiber optic lines, MC 85, Buckeye Water Conservation & Drainage District transmission canal, and Roosevelt Irrigation District facilities. The scope was a complex project that involved multi-agency coordination, including the City of Goodyear, Palo Verde Nuclear Power, Arizona Public Service, and BWCDD. Similar goals include providing a flood control facility at the Gila River and boring under the Union Pacific Railroad. As an example of utility avoidance and right-of-way considerations, this was a complex project that involved multi-agency coordination, including the City of Goodyear, Palo Verde Nuclear Power, Arizona Public Service, and BWCDD.
