#245115 Shelton Ditch Improvements

Marion County and the City of Salem are seeking a comprehensive infrastructure and ecological restoration project for the Shelton Ditch Improvements, specifically focusing on Phase 1 - Reach 4. The procurement opportunity (#245115) involves improving approximately 1.5 miles of the Shelton Ditch, extending from Ford Street SE to east of 24th Street SE, with substantial engineering and environmental rehabilitation components. The project encompasses stream corridor restoration, bank stabilization, revegetation, and irrigation improvements, with construction activities strictly confined to the in-water work window of July 1 to October 31. Potential contractors must demonstrate capabilities in civil engineering, landscape restoration, and environmental construction, with expertise in native plant installation, riprap implementation, and high-performance turf reinforcement mat (HPTRM) slope treatments. The contract requires detailed implementation of native plantings, including approximately 132 individual trees and shrubs such as red alder, bigleaf maple, Douglas hawthorn, and multiple willow species, along with seeding 0.187 acres with native riparian and wetland seed mixes. The solicitation was posted on March 14, 2025, with proposals due by April 8, 2025, and an engineer's estimated budget range of $705,000 to $880,000.

While no specific set-aside designations were explicitly mentioned in the available documentation, potential bidders should anticipate standard municipal procurement requirements typically associated with public infrastructure projects. The project does not indicate incumbent vendors or specific integration requirements with existing infrastructure, though contractors will need to coordinate closely with Marion County and Salem Public Works departments. The comprehensive nature of the design plans suggests a robust project requiring advanced ecological restoration and civil engineering capabilities. Prospective bidders should carefully review the detailed project manual and combined stamped plans, which provide extensive technical specifications for successful proposal development. The budget range of $705,000 to $880,000 indicates a significant capital investment in local infrastructure and environmental restoration, suggesting the project will require contractors with substantial technical expertise, environmental knowledge, and financial capacity to execute the complex rehabilitation of the Shelton Ditch corridor.
