8. City commenced General Plan update process in 2008, including traffic study Higher than expected future traffic forecasts Recommendation for a series of substantial infrastructure improvements Background City of Tehachapi Short-term Programming Model

9. Future Problems

10. Concerned that projected growth and need for new facilities were not consistent with historic growth patterns Desire to maintain its “small town” feel and current neighborhood-based roadway network Need to address funding and timing requirements if improvements needed City’s Issues City of Tehachapi Short-term Programming Model

11. Focus on the anticipated 5-10 year growth Identify improvements needed to maintain acceptable near-term roadway operations Establish a phasing plan Format for customization / easy updating Solution City of Tehachapi Short-term Programming Model

12. Background growth: Intracity (trips with origin or destination outside city) Intercity (trips with both origins and destinations within city) Series of planned/approved projects Future Volume Development City of Tehachapi Short-term Programming Model
