F-3. RESOLUTION 2008R016 ARIZONA CANAL DIVERSION CHANNEL (ACDC) STORM DRAIN IMPROVEMENTS Adopt Resolution FCD 2008R016 for the design and construction of the Arizona Canal Diversion Channel (ACDC) Storm Drain Improvements (Project). This Project is within the Supervisory Districts 3 and 4 in the central part of the valley within the City of Phoenix . The United States Army Corps of Engineers (USACE) constructed the ACDC in the early 1980s in cooperation with the Flood Control District of Maricopa County (District). The District currently owns, operates and maintains the channel. Storm drain inlet pipe cracks are developing about 4’ from the wall of the ACDC. The cracks in the pipes allow storm water flows to enter into the wall backfill causing the backfill to be saturated and further consolidate. Continuation of seepage behind the ACDC wall can cause further damage to the existing wall that is 20’ in height. The District is requesting authorization to design and construct the improvements to existing cracked inlet pipes that will preserve the ACDC integrity and functionality, and budget necessary funding. This Agenda Item impacts Supervisory Districts 3 and 4. (C-69-09-037-6-00)
