4 HOW WILL SOUND TRANSIT WORK WITH PROPERTY OWNERS? Ongoing Property Owner Outreach We are here 2016 Environmental review Pre-final design 60% design Start construction Property owners contacted prior to the publication of the Draft Environmental Impact Statement (EIS), Supplemental EIS and Final EIS. Field work During pre-final design, Sound Transit will test soil conditions and ground water levels, conduct field surveys, and perform utility locates. This work will require individual rights-of-entry within public and private properties. All properties requiring rights-of-entry will be contacted by Sound Transit representatives. Property acquisition process In 2013 and 2014, the Sound Transit Board approves right-of-way authorization identifying which properties will be necessary to build and operate the project. 1. Right-of-way identified Real property personnel work with civil engineers to identify full or/and partial property needed to build project. 2. Board meeting notice Sound Transit will notify property owners of the Sound Transit Board meeting where the Board will consider authorizing property purchases. Start construction Sound Transit is committed to maintaining open communication with nearby property owners before and during construction. There will be multiple public involvement opportunities and ways to stay informed throughout construction. Sound Transit will work with property owners throughout construction to facilitate access during construction sequencing. Questions?
