Third Brook Third Brook stream bed instability and hill slope failures Third Brook hill slope failures were identified in the Third Brook Watershed Management Plan ACOE WRDA funded ($510 K) through the Department of Watershed Affairs matched with DEP funds ($170 K) to stabilize slopes contributing sediment and woody debris to Third Brook above the Village of Walton Goal was to reduce stress on slope toe, halt head cuts and bed degradation upstream, and reduce sediment deposition downstream in the village Originally projected costs to address all slopes (1-9) exceeded WRDA funding so project was segmented
Third Brook Sites 8 & 9 Original work took place in 2014 Spring 2015 rains resulted in flanking of EWP structure and stream bank failure Some ACOE funds remained from 2014 construction and were available for emergency repair work on these slopes DCSWCD also requested additional funds from DEP to facilitate the emergency work
Third Brook - Sites 8 & 9 Design DCSWCD requested design assistance from Milone & MacBroom through DEP The project was in part an emergency repair with additional funds provided to install boulder riffle structures and revetment (rip-rap) along the toe of slope Total length: 1,145.5 ft Total Cost: $807,638 (2014 & 2015)
Third Brook Sites 8 & 9 Construction
