Phil Quarterman is a Wetland Scientist with Winterbrook Planning. He has 43 years of experience in natural resource planning and wetlands, both in the public and private sectors. His depth of experience with wetlands includes, but is certainly not limited to, permitting, rare plant surveys, mitigation site construction, planting and monitoring, and wetland delineation. His passion for projects that leave a natural resource legacy knows no bounds.

“Real satisfaction comes from projects that leave a natural resources legacy.”

Phil began his career as a city planning assistant in England with the City of Manchester. Through his endeavors with urban planning, he became enamored with the natural environment, and soon decided to pursue these interests. He decided to move forward by relocating to the Pacific Northwest, where he received his Master of Environmental Science at Washington State University, and gained a broad grounding in natural sciences and resource planning. He went on to work with Coos County Planning Department, the Oregon Department of Land and Conservation and Development (where he met Greg Winterowd), and Oregon Department of Transportation Environmental Section, WHPacific, and finally Winterbrook Planning. He also is a part-time instructor at Clackamas Community College’s Environmental Learning Center, leading a workshop in Wetland Delineation.

Beyond his passion for getting involved with the wetland and natural scientist communities, he can be found building his own accessory dwelling unit (and future home), growing his own food and making his own cider, hiking, and following the Portland Timbers.

Representative Projects:

Coquille Bypass Wetland Mitigation
Phil took 60 acres of grazing land in the floodplain on either side of the new roadway, and designed a series of linked ponds connected to the tidally influenced river and ringed by willows. They were soon utilized by juvenile coho salmon as a refuge  during flood events and for rearing during the year, much to the pleasure of ODFW and local fish and wildlife groups. 

North Bend Airport
The North Bend Airport needed a safety area extension into the Coos Bay estuary.  Phil’s mitigation site involved removal of a section of dike from a pasture, and restoration of 10 acres to tidal mudflats and low salt marsh on Haynes Inlet. The landowners he worked with now overlook a wonderful area for waterfowl and shorebird watching, and part of their lowland is still available for haying and grazing. 

Red Dog Mine
Red Dog Mine is a zinc mine located in the far northwest, north of the Arctic Circle, which provides revenue to support the Inupiaq people of that area. Phil led a team that delineated wetlands and streams along two alternative corridors for an access road to a new ore body, looking for the least impact alignment. He spent long days in the tundra establishing sample plots and documenting the extensive bogs and riparian wetlands, reaching his study area each day by helicopter, and persevering through fog and drizzle, while also enjoying several wonderful mild sunny days.
