Purpose and Need
• Provide an Airport that conforms to Federal Aviation
Administration (FAA) airport design standards, criteria, and
orders.
• Ensure the reliability of an airport serving the Wood River
Region by providing approach capability that will allow
operations during periods of reduced visibility. At a
minimum, provide an approach capability providing for
operations down to a ceiling of 200 feet above airport
elevation and one-half mile visibility.
• Ensure the ability of the airport to accommodate growth in
operational demand and in demand for new and expanded
facilities.

Aviation Demand Forecast
• Historical Activity
• Enplaned Passengers
• Aircraft Operations
• Stakeholder Interviews
• Passenger Forecast
• Aircraft Operations Forecast

Passenger Forecast Methodology
• Scenarios
• Constrained (existing airport)
• Unconstrained (replacement airport)
• Constrained forecast relies upon analysis of
historical traffic
• Unconstrained forecast considered:
• Reduced leakage to Boise and Twin Falls
• Airport choice data from stakeholder interviews
• Potential new air service
• Level of air service at similar resort areas

Aircraft Operations Forecast
• Under the constrained scenario, passenger aircraft
operations would remain in the historical range,
although SkyWest has announced its intent to remove
the Embraer 120 aircraft from the fleet by 2012.
• Following the opening of the replacement airport the use
of narrowbody aircraft is possible and expected.
• Due to the larger capacity, passenger aircraft operations
would decline.
• General aviation operations are forecast to grow at
1.3 percent per year, in line with national trends.
• Total aircraft operations are projected to grow at
0.7 percent per year from 2007 to 2021.

Alternative Sites Analysis – General Site
Facility Parameters
• Provide a primary runway alignment of 8,500 feet in length
• Where necessary ensure crosswind runway capability of
80 percent of primary runway length
• Conform to FAA design standards for Design Group C-III
aircraft
• Provide a minimum of 50 acres for terminal area & terminal
support development
• Provide a minimum of 75 acres for general aviation/FBO
development
• Ensure expansion capability for terminal and general
aviation/FBO beyond initial specified areas
• Provide a total site area that meets all of the above
requirements

Alternative Sites Analysis – Three Tier
Process
• Identified full complement of sites to be evaluated.
• Developed a process to assess the attributes and
constraints of each site.
• Developed a total of 14 evaluation criteria used to assess
the sites.
• Tier One - used to identify any sites that could not meet
“Fatal Flaw Criteria.”
• Tier Two - employed a broader set of criteria using a
numerical scoring system.
• Tier Three - used to determine the flexibility of a site to
provide for expanded approach capabilities.

Tier One Evaluation Criteria
Tier One Evaluation – Fatal Flaw Analysis Criteria
• Inability to provide Category I approach minimums (200-foot
ceiling and one-half mile visibility)
• Outside of a 60-minute drive time from Ketchum/Sun Valley,
Hailey/Bellevue, and Carey
Alternatives failing to meet one or both of the above were
dropped from further consideration.

Results of Tier One Site Analysis
 All existing airport options failed Tier One based on
Approach Capability.
 Sites 2, 3, and 16 failed Tier One based on Approach
Capability.
 Sites 7, 8, 11, 14, and 15 failed Tier One based on the drive
time criteria.
 Sites 4, 5, 6, 9, 10, 10A, 12, 13, and 17 were recommended
for evaluation under the criteria in the Tier Two evaluation.

Tier Two Evaluation Process
 Tier Two Criteria applied to each site carried forward.
 Several Tier Two criteria are comprised of multiple subcategories that combine to make up the primary category.
 All primary and sub-element criteria were numerically ranked.
 Scores were tabulated for each evaluation criteria and a total
score for each site was calculated.
 A score exceeding the 80th percentile was necessary to be
moved forward in the process for further consideration.

Results of Tier Two Analysis
 Sites 5, 6, 9, 10, 13, and 17 did not move on to the Tier
Three evaluation due to scoring below the 80th percentile in
the Tier Two evaluation.
 Sites 4, 10A, and 12 were recommended for evaluation
under the criteria in the Tier Three evaluation.

Tier Three Evaluation Process
 All three sites provide a single Category I approach and
some form of missed approach capability.
 Each site was reviewed for ability to accommodate
enhanced instrument approach capabilities in the future.
 Evaluated additional Category I capability and Category II
capability at each site.
 Goal was to define those sites with greatest flexibility to
meet future capabilities and opportunities.
 A site not providing any added capability or flexibility would
not move forward if other sites met this criteria.

Results of Tier Three Analysis
 Site 4 accommodates Category I to both runway ends, but not
Category II.
 Site 10A accommodates Category I and II to both ends of the
primary runway.
 Site 12 accommodates Category I and II to both runway ends.
 Sites 4, 10A, and 12 recommended to be carried forward to
Phase II of the EIS.
