    Dibble provided survey and civil engineering services that included the preparation of a utility master plan encompassing a one square mile area surrounding the Civic Center Campus as well as roadway plans for Civic Center Drive. The roadway infrastructure plans encompassed final construction documents as well as Engineer's probable cost estimate for over 2,000 LF of Civic Center Drive, multiple culvert crossings, and signing and striping. This master plan will act as the framework for future development on the campus. Dibble also prepared a Master Drainage Plan including an offsite drainage analysis using HEC-1 as well as detention basin routing onsite and roadway drainage analysis for the City of Surprise's 13-acre Civic Center development project. The report provided recommendations which will help guide future on-site development decisions. This was done by considering multiple scenarios for on-site detention/retention and evaluating each scenario for their impact on downstream property owners.
      Dibble provided civil engineering and limited construction administration services for the City of Avondale Civic Center located on a 60-acre site that includes City of Avondale, Maricopa County, and private commercial properties. The Civic Center comprises City Hall, the City Police Facility, and a Courts Building. Off-site drainage issues required extensive study and an economical resolution in the design. The site required retention of additional runoff from the adjacent parcel to the north through a network of retention basins on the site. The City concurrently designed and constructed the roadway improvements of Avondale Boulevard (formerly 115th Avenue). Extensive coordination with the roadway and utility designers was vital throughout the project design.
