1. Length of toe block is 10' minimum.
2. Grid should extend from face to
contact with in -situ slope.
3. Grid strength is 400 Ibs /linear foot.
4• Tensor - 6X1200 will meet grid
requirements.
SITE PREPARATION
1. Slope to be cleared of all organics. logs and
root wads to be saved and used along MHW
line after slope completion.
2. Construction road to be regraded to
approximate original grade and all drainage
restored, surface to be covered with
permanent growth cover with temporary
erosion control features.
3. All work on shore area to be done in dry at
lower tides.
4. For rock armor provide Ten -Cate N160
geotextile against native soil and minimum of
6" thick, crushed rock bedding.
