East Main Street Improvements

Client—City of Elma, Washington

Gibbs & Olson provided design and construction phase services for the East Main Street Improvement project. Improvements consisted of reconstruction and widening of 2,100 feet of roadway including a new center turn lane, sidewalks, drainage, and illumination. Stormwater is collected and conveyed into a below grade treatment and infiltration gallery under the sidewalks. The project required SEPA/NEPA documentation, and right-of-way assessment and acquisition. A new 8 inch ductile iron waterline was designed, in conjunction with the roadway design, to replace 2,000 feet of existing 8 inch asbestos cement water main.
