1 DINGMANS CREEK, SITE 4, SMALL SLIDE, DELAWARE WATER GAP PROJECT VEGETATED KEYS; TRAFFIC CONTROL STONES; PLANTINGS; SINGLE STONE BENDWAY WEIRS; & A RANDOM BOULDER FIELD FOR ROUGHNESS & AQUATIC HABITAT

2 PRE-PROJECT PHOTOS by Dave Derrick Dec. 15, 2008 (HIGH WATER) LEAF OFF CONDITION

3 HIGH WATER-Looking US @ project bank. Stream is obviously eroding this bank, which contributes significant sediment to the system PRE-PROJECT DINGMANS CR-SITE 4 PIX BY DERRICK 12-15-2008

5 THE PLAN

6 Courtesy of Ecological Restoration, Inc. Correction: There should be 3 Traffic Control Stones between each Single Stone Bendway Weir, not 2.

7 Courtesy of Ecological Restoration, Inc. SSBW TCS Key

8 PLANTS PLANTED  Gray Birch 50 2 gallon pots  Gray Birch 200 unrooted poles  Buttonbush 25 bare root  Silky Dogwood 200 bare root  Ninebark 175 bare root  Rhododendron 50 3 gallon pots  White Pine150 3 gallon pots Common Name # Size

9 Two healthy Single Stone Bendway Weir (SSBW) stones. CONSTRUCTION DINGMANS CR-SITE 4 PIX BY DERRICK 9-19-2009

10 CONSTRUCTION PHOTOS by Dave Derrick, September 19-20, 2009

11 Traffic Control Stones (TCS) sized about 3 ft by 3 ft by 4 ft, dug into the bed & bank, designed to stabilize & roughen the bank, are spaced 3 to 6 ft apart. Every 4th TCS is keyed into the bank & has a Single Stone Bendway Weir attached. 8 SSBW total Traffic Control Stones (TCS) with Single Stone Bendway Weirs (SSBW) & vegged keys & pole plantings Key TCS Key TCS SSBW TCS SSBW Key Thalweg Key

12 Rooted–stock container shrubs & trees added to Traffic Control Stones at toe & all bare areas of the entire eroding bank Key TCS Key TCS SSBW TCS SSBW Key Thalweg

24 CONSTRUCTION COMPLETE Photos by Dave Derrick SEPT. 24, 2009 Very natural, minimal structure approach

25 Construction complete, looking DS @ 175 ft of the 200 ft long project. This should look completely natural in a couple years!! CONSTRUCTION COMPLETE DINGMANS CR-SITE 4 DERRICK 9-24-2009

26 Construction complete, looking DS. TCS, Single Stone Bendway Weirs, random boulder field, many pole plantings & rooted-stock plants provide plenty of roughness @ toe of slide. CONSTRUCTION COMPLETE DINGMANS CR-SITE 4 DERRICK 9-24-2009
