Big Hanaford Creek Monitoring and Management 
Centralia, WA

Cascade provides mitigation site permit compliance monitoring and manages site maintenance for two large mitigation projects in Centralia, WA. The two sites total 149 acres of mitigation area, including over 7,000 linear feet of creek re-alignment, aquatic and wetland habitat enhancement, weed management, and re-vegetation work.

We monitor stream flow, groundwater, vegetation performance, and habitat design features through quantitative and qualitative methods to ensure site performance objectives are met. Site maintenance includes herbicide application prescriptions, supplemental planting design, and herbivorous control implemented under an adaptive management framework.

Cascade coordinates with regulatory agencies and produces quarterly and annual technical reports outlining monitoring methods and results, assesses site development and effectiveness of management efforts, and provides management recommendations to the client.
