Phases 1, completed in 2010, included improving stormwater infiltration by installing a level spreader, a bioretention swale, a rain garden, and porous pavement on the golf course clubhouse patio.
Phases 2- 3 were completed during the summer of 2011. Fallen logs found on site were reused for wildlife habitat and edging, and invasive trees and vegetation were replaced with native forest plant species including trees, shrubs and herbaceous groundcover.
Phase 4, completed during summer 2012, continued along the Lower Slope moving further away from the golf course with slope stabilization, gully repair and planting. After completion of Phase 4 work, access will be restricted through the use of temporary fencing to allow vegetation to get fully established.
Phase 5, completed fall 2016, installed porous paving and a permeable cobble swale to enhance runoff infiltration at the bottom of the slope and improve Perimeter Road surface and drainage. The damaged fence along the Perimeter Road was replaced and the curb re-set. Restoration plantings were installed at the toe of the slope.
Planning began for the Glacken Slope Improvements project in 2008. The Bioengineering Group (now Chester Engineers), the landscape architecture company chosen to lead the project, suggested a pilot project below the Golf Course Clubhouse to test innovative solutions to steep slope stabilization techniques. This kicked off Phase 1 of the multiphase ongoing project to re-stabilize and restore the native species of the slope.
