Project Summary

Client: City of Pasco
Location: Pasco, WA
Services Provided:
  • Civil Engineering
  • Landscape Architecture
  • Public Involvement
The 3.5-mile Argent Road corridor serves as the front door to the Tri- Cities Airport, Columbia Basin College, and the Port of Pasco’s Business Park, and also features a large number of vacant parcels ripe for development. The corridor is experiencing increased congestion as the area continues to grow, driving the need for major street improvements.
The goal is to design a ‘Complete Street’ that will serve as a showcase for people entering the community. The project incorporates low impact development stormwater design elements where the landscaping will be used for water quality and to aesthetically enhance the roadway.
MacKay Sposito started by evaluating the expansion of the corridor and providing conceptual design. Our evaluation included planning for a future west-bound connection to Interstate 82 and east-bound off ramp, evaluation of infrastructure needs, and reconfiguration of access points to a variety of land uses including the Port of Pasco and Columbia Basin College.
During the conceptual design process, we analyzed the existing planning work that occurred over the prior 6 years to ensure integration of those plans and the proposed improvements. Streetscape and pedestrian improvements were also evaluated to enhance the aesthetics.
MacKay Sposito’s civil engineering and landscape architecture teams also prepared the final design. Additionally, we provided public involvement assistance to the City.
The City is currently seeking state funding to construct the project.
