1 ACCOTINK CREEK @ AIRFIELD RUNWAY & RECHLORINATION PLANT PROJECTS GARRISON FORT BELVOIR, FAIRFAX, VA CONSTRUCTED Dec 2-5, 2008

2 LONGITUDINAL PEAKED STONE TOE PROTECTION (LPSTP) Built with Virginia DOT Class II stone, level-crested @ 3 ft above the base-flow water surface elevation & trenched 3 ft into the bed. One row of live willow poles (3 poles/ft) planted in the LPSTP & another row (3/ft) laid on top of LPSTP (termed Live Siltation).

3 STEP-BY STEPS FOR ACCOTINK CREEK, FT. BELVOIR, VA Toe-down Enhanced LPSTP All drawings by Dave Derrick

4 Typical cross-section for Accotink Creek in the proposed project area ACCOTINK CREEK, FT. BELVOIR, VA LOOKING UPSTREAM

5 Dig toe-down section of LPSTP 3 ft below bed of stream ACCOTINK CREEK, FT. BELVOIR, VA

6 Place Longitudinal Peaked Stone Toe Protection (LPSTP) stone in trench

7 3 ft deep trench dug, tracked backhoe placing 150-500 lb stone CONSTRUCTION-ACCOTINK CR.-RECHLORINATION - DERRICK 12-2008

8 Looking across. Backfilling eroded bank with suitable soil & placing stone as LPSTP. CONSTRUCTION-ACCOTINK CR.-RECHLORINATION- DERRICK 12-2008

9 Looking across @ close up of LPSTP stone. CONSTRUCTION-ACCOTINK CR.-RECHLORINATION - DERRICK 12-2008

10 ACCOTINK CREEK, FT. BELVOIR, VA Place Joint Planting (live willow poles) on top of stone (angled up at least 20 degrees) at the rate of 3 poles per lineal foot.

16 Looking US @ completed LPSTP & poles & dug trench (beyond) CONSTRUCTION-ACCOTINK CR.-RECHLORINATION - DERRICK 12-2008

17 Looking US. LPSTP has been soil-choked. Unfinished LPSTP in background, live poles not installed yet. CONSTRUCTION-ACCOTINK CR.-RECHLORINATION - DERRICK 12-2008

18 ACCOTINK CREEK, FT. BELVOIR, VA At 35 ft spacing intervals, stone Bendway Weirs will be installed that will move the thalweg away from the toe of the LPSTP.

19 LPSTP with Joint Pole Plantings & Live Siltation with an Erosion Control Blanket

20 ACCOTINK CREEK, FT. BELVOIR, VA Tuck the Erosion Control Blanket (ECB) at base of slope. The ECB used here is a 100% coir (Coconut fiber) Rolanka BioD-Mat 40 Roll ECB out over willows & LPSTP stone.
