The northern portion of the Blaine Wetland Sanctuary has been designated as site 7 by regulatory agencies for the purpose of creating a wetland bank. Site 7 is the second wetland bank that was created in the Blaine Wetland Sanctuary.
In 2015, the City of Blaine contracted with Critical Connections Ecological Services to start the process of developing a restoration plan for site 7. Site 7 is approximately 180 acres of open space that will remain as open space forever. Restoration work on site 7 started in 2017. Restoration work included the removal of invasive, non-native species. Methods used during restoration included, tree removal, prescribed burns, and targeted herbicide treatment. In 2020 the restoration work will turn to long term management of the site.
The money generated by the wetland bank will be used for maintaining and augmenting the city's parks, trails, and open spaces.
