Premier provided land survey services for Valley Metro’s Advanced Conceptual Design. The project site runs approximately 3.5 miles along Mill Avenue from Southern Avenue to Rio Salado Parkway and along Ash Avenue from Mill Avenue to Rio Salado Parkway. Our services included creating an electronic base drawing based on research and review of existing underground utility drawings as well as data provided by Valley Metro. Existing underground utilities identified at ASCE Quality Level B were surveyed and added to the electronic base drawing. In addition, 54 panels were set for a large area aerial photography and for aerial mapping of the Mill Avenue and Ash Avenue corridors. A topographic survey was also performed as a supplement to the aerial mapping.
