Executive Summary
EXECUTIVE SUMMARY
Proposed Development Plan
The Karuk Casino project is a 800 gaming position casino and 80 room hotel development on the north
side of Sharps Road, east of Fairlane Road in the City of Yreka. Phase 1 of the project consists of a 500
gaming position (14,200 square feet) casino. Phase 2 (total project) would add an additional 300 gaming
positions (9,500 square feet) to the casino, for a total of 800 gaming positions or 23,700 square feet, as
well as an 80 room hotel.
Trip Generation
Based on the Institute of Transportation Engineers (ITE) Trip Generation, 9th Edition (commonly referred
to as the ITE Trip Generation Manual), combined with trip generation studies of previous, similar casino
projects, the project descriptions for the Karuk Casino generate a maximum of 159 PM peak hour trips
and 1,689 daily trips.
The project’s traffic impacts were estimated by considering the amount of traffic to be generated by
the project and the direction distribution of that traffic. Only the PM peak hour was analyzed for this
project because a casino generates most of its weekday trips during the PM peak hour.
FINDINGS
Existing No Project Conditions
All study intersections were found to be operating at a satisfactory level of service based on the
applicable standards.
Existing Plus Project Phase 1 Conditions
With the addition of project traffic from Phase 1,
 All study intersections are expected to perform satisfactorily per the applicable standards.
Based on the City of Yreka General Plan1 and Caltrans Traffic Impact Study Guidelines2, no impacts are
considered significant.
