Glacken Slope Improvement Project

Glacken Slope after stabilization fabric has been placed.

A high priority in the Fresh Pond Reservation Master Plan, the focus of Glacken Slope Restoration is to stabilize the slope, improve soil infiltration, control storm water runoff, and enhance habitat quality. A phased restoration approach, this project involves slope stabilization and gully repair, community-based restoration plantings, improving drainage to the Perimeter Road, and integrating the Upper Slope with the Glacken Field re-design.  

Phases 1 - 4 of the Glacken Slope Improvements have been completed. Phase 5 is currently in the planning phase and construction is expected this summer, 2013. 

Check back soon for more information on Phase 5 and for Public Meeting notices.

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, slated for this summer (2013) will use porous paving to enhance runoff infiltration at the bottom of the slope and improve Perimeter Road surface and drainage. The damaged fence along the Perimeter Road will be replaced and the curb re-set.

 

Planning began for the Glacken Slope Improvements project in 2008. Bioengineering, 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.
