Stevens County Floodplains Design

Ardurra's geospatial team provided digital engagement support for the Stevens County Floodplains by Design Colville River Project, creating public outreach tools for the secondary floodway terrace development on agricultural lands south of Chewelah. The project encompasses approximately 4,000 feet of the Colville River, addressing dredge spoil removal and site stabilization within the river's historic floodplain, which lies four feet or less above the current channel.

To support permitting processes, Ardurra developed a public website featuring background information and an interactive web map with LiDAR-derived relative elevation models of the project area. The digital platform enables stakeholder engagement through comment submission capabilities linked to specific map locations, facilitating targeted feedback on the Pilot Project and suggestions for future floodplain improvements throughout the valley.

Key Geospatial Services:

• Created a public website providing background information and interactive web mapping for the Colville River floodway project

• Developed LiDAR-derived elevation models showcasing relative topography within historic floodplain areas, supporting project visualization

• Integrated stakeholder comment system enabling public feedback submission with geographic location linking through an interactive map interface

• Established future project suggestion platform encouraging community input on additional floodplain improvement opportunities throughout the valley

• Provided an internal dashboard system enabling County staff to view, query, and export public comments for permitting and planning analysis

• Supporting 4,000-foot floodway development, creating a secondary terrace, removing dredge spoils, and stabilizing disturbed agricultural sites

• Enhanced permitting process support through digital engagement tools, facilitating regulatory coordination and community involvement

The digital engagement platform offers Stevens County innovative stakeholder coordination capabilities, supporting the Pilot Project's permitting requirements. Interactive mapping and comment systems enable community input supporting floodplain restoration and agricultural land management objectives throughout the Colville River valley.
