35 Years of Success in Conservation and



Mark has a proven record of success and innovation in conservation, land use and open space protection. He worked at King County for 30 years with a concentration in land use,  zoning, conservation finance, land use incentives and landscape planning.

As the Chair of the diverse, 39-member Snohomish Basin Salmon Recovery Forum, Mark worked with 14 cities, King and Snohomish Counties, the Master Builders Association, Boeing, the Tulalip Tribe,

local outdoor enthusiasts and the environmental community to craft an effective and balanced plan to recover salmon in the Snohomish River Basin. This important work was built on the best available science and the participation of scientists from member agencies, the Tulalip Tribe, NOAA and the Forest Service. William Ruckelshaus, the first head of the EPA, called this consensus-based Salmon Conservation Plan a“regional model” for the other Puget Sound watersheds.​
