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

Gulf Brook Streambank SMIP

 Located in the Town of Andes  Bank erosion along a town road due to channel incision caused by the 2007 flood  The project was awarded a SMIP grant in 2011, design postponed to 2014 due to Hurricane Irene in 2011 and EWP projects  Project designed by DCSWCD

Walton Green Space Project

• f

Walton Walton Greene Space $20,000 to complete final grading

 Located at the site of the former Walton Reporter building  Goal is to allow conveyance of flood waters from Delaware Street back to West Branch Delaware River  Senator Bonacic grant ($100 K) and local contributions from the Town of Walton ($20,678), Village of Walton($33,295), and Delaware County ($17,685) for purchase and removal of Walton Reporter building  Stream Management Program contributed $20,000 for floodplain grading and installation of stormwater infiltration trench

Walton Gravel Study SMIP

 Walton High School Environmental Science students completed cross- sectional surveys and pebble counts at eight stream sites in the Village of Walton from 2013 - 2015  Determine if stream channel is aggrading, degrading, or in equilibrium  Presented results to Walton Flood Commission on November 5, 2015

More Restoration Project

 Located in the Town of Hamden  Site identified in WBDR Stream Management Plan as lacking adequate riparian buffer  Gradual bar formation and down valley meander migration has resulted in

• ver widened condition

 Project goals:

• establish stable stream

channel that maintains proper sediment transport

• establish riparian buffer

for long term stability of reach
