Since 1996, Heffron Transportation has assisted Pierce County with master planning, development review, and transportation impact analyses for its Chambers Creek Properties in the City of University Place, Washington. The original Master Site Plan and EIS, for which Heffron Transportation prepared all the traffic and parking analyses, was adopted in August 1997. Subsequently, Pierce County has developed its award-winning Environmental Services Building on the site and completed its Chambers Bay Golf Course in 2007. The Robert-Trent-Jones-II-designed 18 hole-championship golf course is host to the 2015 U.S. Open and 2010 U.S. Amateur Championships. Heffron Transportation supported the recent golf-course master planning process as well as the SEPA review and permitting effort. Heffron Transportation also assists Pierce County with Master Site Plan Updates and supplemental environmental review. Elements reviewed for the site include an environmental education center, conference facilities, and an off-leash dog play area.
