Slide 1 Community meeting to explain the road reparation and the protection of the infiltration gallery downstream from sedimentation from eroding streambank. Local concerns were expressed to also fix the existing wells used by the community, in exchange for community work on the restoration effort. (Inset upper right) Original state showing hurricane damage. Note power pole. (Inset upper left) Photo showing anchor, bulldozer used to shape eroded streambank, ox carts and community involvement.
Slide 2 Community meeting. Agreement reached for three improved wells (Bomba de mecate or Rope pump) (Upper insets) new wells constructed, with well committees in exchange for community involvement (15 days/20 persons) exceeded. (Lower inset) original community well
Slide 3 Repeat of community initial work showing again constructed anchor, bulldozer, and ox-carts. Taking advantage of local materials and community labor.
Slide 4 Original hurricane damage to the road (inset) representation of re-shaping bank. Streambank re-shaped with large erosion proof boulders for spurs placed.
Slide 5. Live stakes, fascine bundles planted in skeletal soils. Stones below the waterline, and as rip-rap with trees (Salix humboltidiana) planted between. Spurs installed against the current. Note position of power pole. (Inset) Diagram from stream corridor restoration handbook, NRCS
Slide 6 Watering of bioengineering works by community members to ensure establishment. Necessary skeletal soils with reduced water-holding capacity. (Inset) Diagram from stream corridor restoration handbook, NRCS
Slide 7 Progress after two months. Some trees are actively growing, sprouting of fascines. Paint on exposed ends is to reduce transpiration.
Slide 8 18- month progress. Note the position of the power pole position on the highway.
