Great Land Trust executive director Phil Shephard led a walk to the Campbell Creek Estuary on Anchorage's western coast. The tour included U.S. senators Mark Begich, D-Alaska, and Ron Wyden, D-Oregon, U.S. Fish and Wildlife director Dan Ashe and others. Shephard said he hoped to show the dignitaries a successful example of a public-private partnership in conservation of important wildlife habitat and wetlands. Shephard said Great Land Trust raised more than $7.7 million to purchase the 60-acre parcel at the estuary, create a long-term plan for managing it and build a parking lot and trail head. Great Land Trust purchased the property in 2010 and transferred it to the city to become a "natural area" under municipal Parks and Recreation. Public comment on the master plan opens Wednesday, Aug. 29, and continues for two weeks, Shephard said. The area could be open to the public by the middle of next summer.
