This multi-phase, CMAR project for the City of Chandler began with Gilbert Road Improvements - Germann Road to Queen Creek Road in 2008. The widening and improvements project included 4.5 miles of roadway and more than 63,000 LF of regional wet utility upgrades (including storm drain, water, reclaimed water, sanitary sewer, SRP Irrigation, and RWCD Irrigation). Work also included expansion of 4 intersections and OH to UG conversion of SRP distribution and transmission.

Also, the project included the installation of 3,697 LF of Roosevelt Water Conservation District (RWCD) irrigation lines, 671 LF of sanitary sewer lines, 9,576 LF of water lines, 2,349 LF of reclaimed water lines, and the undergrounding of SRP 12kV distribution lines.
