Mitigation Conservation Banking - Bobcat Marsh
Bobcat Marsh Mitigation Bank - Hillsboro, Oregon
ODOT is partnering with the Port of Portland (POP), Clean Water Services (CWS), and the City of Hillsboro (City) to restore historical wetlands, enhance existing wetlands, and re-route the channelized Jackson Slough ditch into wetlands to increase the hydration of existing wetlands. This will be accomplished by re-grading and re-planting the approximately 18-acre project area.  The proposed Bobcat Marsh Mitigation Bank (BMMB) is located within the Jackson Bottom Wetland Preserve (JBWP), a 725-acre preserve that is owned by the City and managed by dedicated JBWP staff for educational purposes and natural resource values.
BMMB will be used to mitigate wetland impacts associated with highway projects in the Tualatin Basin.  ODOT has an ongoing need for mitigating small impacts to disturbed roadside wetlands throughout the basin.  The Port needs a mitigation site to compensate for impacts to wetlands due to the Hillsboro Runway Expansion project.  Rather than conduct mitigation on a project-by-project basis resulting in areas of small, low-functioning wetlands adjacent to highways and the new runway, the partnership will consolidate its efforts into a larger project which will provide a higher-functioning wetland that will be protected and managed in perpetuity.  The project is consistent with the area’s existing and potential land uses.
