In the 1860s Hermiston was known as a hotel called the “Six Mile House,” a stop for travelers in the Columbia River Basin. Following the establishment of railroads, the City was incorporated in 1907. Approximately eight square miles in area, Hermiston currently has more than 19,000 residents. Hermiston’s employment rate is 62.1%, agriculture as an economic asset to which is above Oregon’s employment the City.

In the early 2000s, Hermiston had a population of about 13,000 people. With more homes and schools under construction, the town expects to reach a population of 20,000 in the next decade. Hermiston is a small town, and with a growing population, traffic will increase, causing large amounts of congestion. The congestion will primarily be an issue during peak hours in the morning and afternoon. Most of the congestion occurs on Highway 395. Portland State University capstone At an early design stage, the City students are responsible for designing of Hermiston decided that designing different alternatives that the team will bike lanes was not preferred due to present to the city of Hermiston. The the popularity of using automobiles to report will include CAD drawings, a cost get around town. The team ultimately estimate, and a construction schedule. produced three designs that the City The alternative designs will focus on could look into, not including a no-build easing congestion, providing better option. The alternatives include a new access for residents and commercial street layout from Highway 395 to W establishments, pedestrian and driver Theater Lane, a new street layout from safety, and total construction time.

The will allow the City to incorporate a new new road would also provide better signal at Highway 395. 9 Spring 2022 North Hermiston Local Circulation Plan 1.0 Project Understanding The City of Hermiston, Oregon has identified the need for improvements to traffic flow in the areas surrounding Highway 395 between Highway 207 and Theater Lane. Improvements to access between surrounding residential neighborhoods and this commercial district are needed. Portland State University’s Civil and Environmental Engineering Capstone Program has been contacted to study alternatives and provide a recommendation for improvements to the study area. The primary objective is a preliminary design report at 30% completion delivered to the City of Hermiston. This design report will include cost estimates, potential street layouts, and a timeline for construction. The desired outcomes any to management of these stores, improvements will achieve are: vehicles access and cut through these properties by using undesignated 1.

Intersection Improvement: East Theater Lane and Highway 395 An intersection redesign for East Theater Lane and Highway 395 would include improvements over existing conditions. This would include a slip lane on Highway 395 to reduce congestion in the north-south direction of the intersection, as that direction has the most traffic volume. Because of the developing communities along the east and west sides of Highway 395, improvements could be made for pedestrian users such as a bike lane and better sidewalks. 13 2.0 Alternatives Analysis 2.1.3 Intersection Improvement: of the intersection, as that direction East Theater Lane and Highway 395 has the most traffic volume.

The City of Hermiston is experiencing significant development, which is expected to cause an increase in population. With more people, one can expect more vehicles leading to more traffic. This design aims to create a new road that would decrease congestion on Highway 395, improve access to businesses for pedestrians, and improve overall safety. 5.1 BENEFITS 5.3 POSSIBLE IMPROVEMENTS The benefit of this project is the With this new layout comes new decrease in traffic volumes along sidewalk and curb returns. Each corner Highway 395 and NE 4th Street. will require a new ADA compliant Fewer cars piling up will lead to less ramp so everyone can use the new congestion and allow for better sidewalk. There is also the possibility of traffic flow on Highway 395. Another constructing a left-turning lane with a benefit is the increase in safety for left turn signal. The left-turn lane would both drivers and pedestrians. After prevent cars from having to stop for completing this project, there will be each other and improve the flow of more opportunities for food carts and a traffic.

Another possible improvement would be the addition 5.2 LIMITATIONS of bike lanes, which would both The area where the new street encourage the usage of bikes and make layout is being proposed has high biking an overall safer and less stressful groundwater.
