We manage over 900 acres of wetland and upland mitigation and enhancement sites. These managed natural areas provide compensation for temporary and unavoidable, permanent impacts to wetlands and other natural resources from our development or operational activities. Their benefits include:
We initiated the Mitigation Management Program in 1997 to respond to mitigation requirements and mandates from regulatory agencies. The program continuously evolves to incorporate the latest science and technology. We report annually on sites under compliance and conduct reporting every two years for stewardship on all sites.
Mitigation Management Program Report
The Mitigation Management Program report provides an update on the previous two year's activities for all Port mitigation sites and other natural areas. For each site, the annual report provides permits and agreements, background, mitigation plan, success criteria, permit requirements, activity update, site performance, action plan, and a figure or aerial photograph of the site.
Vegetation Management Plan
The Vegetation Management Plan provides information about invasive species control methods used by the Port on our mitigation sites and natural areas. This document includes background and purpose, invasive plant species profiles, methods and equipment, site maps and Best Management Practices including maintenance timing to avoid and protect wildlife. Although the focus of the plan is the proper use of herbicides, the plan also highlights mechanical and manual means to control invasive species on mitigation sites and natural areas.
The Vanport Wetlands Comprehensive Management Plan is a working document that can be modified as site conditions and priorities change. The document describes the Port's plans for present and future use and management of the site. The Port welcomes comments and suggestions concerning the plan, particularly with regard to key issues and management recommendations.
