Techniques to Reduce Impact
�Locate use on sites that are both resistant and resilient.
�Control drainage & erosion on the site.�Soil preparation & stabilizers.�Planting to stabilize, screen & direct use.�Eliminate, disperse, & rotate use.�Perform preventive maintenance.

Construction Fabrics -- Stabilization for unpaved surfaces
� Separates aggregate from weak soils.
� Confines aggregates by locking bottom layer into a flexible slab.
� Distributes the wheel load over a larger area.

Alternatives to Pavement
� Colored asphalt & concrete.� Pebble-wash asphalt & concrete
(exposed aggregate).� Pavers, cobble stone, corduroy.� Interlocking paver blocks.� Gabions baskets.

Gabion Baskets� Light weight until filled
on site with native rock� Interlocked--large inertial
mass� Water & roots penetrate� Long lasting

Retaining Walls
� Deadman anchors� Water but NOT soil permeable
(fabric)� Over design!
"Design with Nature"
Retaining Walls & deadman anchors
� Ecoblocks -- interlocking concrete blocks (3’W x 3’H x 6’L) 3,500 lbs.
� Retaining wall with solid deadman
� Prevents wall from Tilting or Bowing outwardDrain Pipe

� Ecoblocks -- interlocking concrete blocks (3’W x 3’H x 6’L) 3,500 lbs.
� Retaining wall with Geogrid fabric deadman
� Prevents wall from Tilting or Bowing outward
