Bank reconstruction and stabilization, September 29 - October 6, 2005
Stage 1: Knock down overhangs and build earthen platforms for excavator. Work from top down to smooth slopes. |
|
Stage 2: excavate trench for French drain; hand install perforated pipe at location of seep; crushed stone will be placed over the pipe
Stage 4: Install rock spillway from low point of lawn to bottom of bank; spillway connects with French drain to direct all flow |

|
Stage 6: Hydroseeding with mulch/seed mix on entire surface. Subcontractor: Longfellows Hydroseeding. |
|
Hydroseeding held up fairly well under
torrential rains (6" in one day) shortly after application.
Hydroseed was reapplied on one side of slope where mulch had become
saturated and slid off. Surface runoff from driveway and lawn is going
directly into the rock spillway as intended. |
Tree seedlings and shrubs planted along perimeter to mark the edge of the bank. |
