HILLSBORO AIRPORT PARALLEL RUNWAY 12L/30R ENVIRONMENTAL ASSESSMENT A1-3 APPENDIX A
The following agencies attended the open house:
• Federal Aviation Administration (1)
• US Army Corps of Engineers
• Oregon Department of Transportation
• Washington County (2)
• City of Hillsboro (3)
Public Comments Open house attendees were given ample space to provide their comments on the Hillsboro Runway project through comment forms and chartpaks. Fifteen comments were received from attendees, and another three residents contacted Port of Portland staff to ask more questions about anticipated noise impacts on their property, and to request budget and timeline information about the project.
Through their comments, many people presented concerns about the noise level of construction and the impact of low-flying helicopters on livability for residents in the area. Others noted that the runway presented an opportunity for vital economic growth in Hillsboro, as it would help to attract the high-tech and solar industries.
A summary of all public comments can be found in Attachment 3.
Press Coverage Local media outlets covered the open house as follows:
• The Hillsboro Argus published an article on September 9, 2008, which gave an overview of the new runway construction project and announced the September 11 open house as an opportunity for citizen participation.
• On Wednesday, September 17, 2008, KGW News published an article entitled “Neighbors concerned about new runway in Hillsboro,” which highlighted the differences in opinion between Airport managers concerned about the Airport’s current capacity and that of citizens worried about the construction noise and traffic impacts. The open house and the impacts of the new Hillsboro runway were also discussed in at least two blogs following the event.

September 2008 Open House Agency Letter
Letterhead To: Agency and address ATTN: (contact name or dept) From: Terri Burk
Project Manager, Aviation Facilities Port of Portland
Re: Invitation to Hillsboro Airport Parallel Runway
Public and Agency Informational Meeting
The Port of Portland is beginning an Environmental Assessment (EA) for a proposed parallel runway at Hillsboro Airport. The assessment will follow National Environmental Policy Act (NEPA) requirements in considering environmental impacts and runway alternatives. This notice provides general background information about this project and the areas that we will examine in the EA.
As a designated reliever airport, Hillsboro must provide a convenient alternative to PDX for a wide range of users, including recreational pilots, flight training schools and corporate aircraft operators. Currently, operations at Hillsboro are near capacity and expected to exceed capacity in the upcoming years.
As part of this EA, the project team will host a drop-in information-sharing session for agency representatives Thursday, September 11 from 3 p.m. – 5 p.m. at the Hillsboro Civic Center, 150 East Main Street, Hillsboro, Oregon 97123. During this time, we will have project team members available to discuss your agency’s interests in this effort. A community Open House will follow from 5-7 p.m.
While this is a drop-in event, it would assist our planning if you can confirm your attendance and/or that of an agency representative. Please confirm with Shannon Huggins, Aviation Community Affairs Program Manager, or feel free to contact her if you have any questions about the project or process in the meantime.

FACT SHEET
Port of Portland, Environmental Assessment for a proposed parallel runway at Hillsboro Airport
The Port of Portland is beginning an Environmental Assessment of a proposed parallel runway at Hillsboro Airport. The assessment will follow National Environmental Policy Act (NEPA) requirements in considering environmental impacts and runway alternatives.
Evergreen Road Proposed Parallel
Runway 12L/30R and Associated Taxiways
Proposed Relocation of the Charlie Helipad
Runway 2/20
Runway 12/30
NORTH Cornell Road
The EA will evaluate the impact of the proposed project and its alternatives on the following 23 environmental resource categories identified by the FAA:
• Air Quality • Biotic Resources • Coastal Barriers • Coastal Zone Management • Compatible Land Use • Construction • Section 4(f) • Federally-listed Endangered and Threatened
Species • Energy Supplies, Natural Resources, and
Sustainable Design • Environmental Justice • Farmlands
• Floodplains
• Hazardous Materials Historic and Archeological • Induced Socioeconomic • Light Emissions and Visual Effects • Noise • Social Impacts • Solid Waste • Water Quality • Wetlands • Wild and Scenic Rivers • Cumulative Impacts
The assessment will examine non-development alternatives (such as decreasing demand), different runway alignments and lengths, and a “no- action” alternative.
The project will also analyze the impacts of the relocation of the airport’s helicopter landing pad. This pad is currently located in the area of the proposed parallel runway and it is anticipated that it would be relocated one to three years after the construction of the proposed parallel runway
The Draft Assessment is expected to be published in early summer 2009 followed by additional opportunities for community comment and review.
