Alternative 3: Alternative 3 is a non-gaming option where the casino/hotel shown at the core of the site in
Alternatives 1 is replaced with a hotel and general entertainment component. The components listed below were
used to estimate the amount of traffic generated under Alternative 3. The trip generation rate for the central portion
of the project was based on the hotel, the entertainment components (bowling alley and recreational space), the
external restaurant space, and the specialty retail area. Components within the central building such as the lounge
and conference space were considered incidental and ancillary uses to the primary hotel and entertainment
components, as discussed in more detail in Section 5, Trip Generation and Distribution.

Access to the site is proposed to be provided via three driveways along the Highway 2 frontage (1 full
movement; 2 right-in/right-out) and three driveways along Craig Road.
The project study area for this Traffic Impact Analysis was determined through discussions with
WSDOT, City of Airway Heights and Spokane County. The study intersections include:
Highway 2/ Craig Road
Highway 2/Lundstrom Street
Highway 2/Lawson Street
Highway 2/Garfield Street
Highway 2/Hayford Road
Craig Road/Deno Road
Craig Road/6 th Avenue
Craig Road/McFarlane Street
Craig Road/Thorpe Road
Craig Road/State Route 902
Highway 2/ Fairchild AFB
Site access driveways
The study focused on the traffic operations characteristics of the above intersections. The traffic study
was scoped to include analysis of PM peak hour conditions and includes various analysis scenarios plus
mitigation analysis. The analysis scenario conditions include:
