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.  

8/9/2016 - Contractors have finished installing curbing at the toe of Glacken slope and excavating the porous asphalt reservoir course sub-grade.  Next steps include setting the perimeter road fence posts, constructing the cobble swale, and installing native landscaping.

7/6/2016
- The perimeter road is closed between the mulched switch back trail to Glacken Field and the golf course clubhouse entrance.  Staging areas have been developed in the upper parking lot and the Weir Meadow. Erosion controls have been installed and detour signage has been placed. For safety, please use caution and put your dog on leash if you decide to use the perimeter road between the upper parking lot and the construction zone. Click here for a detour plan.

6/27/16 - Phase 5 construction began. Construction requires the closure of an approx 1,100 foot section of Perimeter Road between the mulched switch-back trail to Glacken Field and the Golf Course Clubhouse entrance.

2/25/2016 - Phase 5 Public Meeting was held Thursday February 25, 2016.  The presentation is available for download from the documents tab.

2010 - 2016 - Phases 1 - 4 of the Glacken Slope Improvements have been completed. 

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 (2016) 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. 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.
