STRUCTURAL COMMENTS
Sheet SW -1
1. The analysis submitted required the wall to be battered back 4 degrees but the
drawings note vertical not battered. This is very important. This wall acts as a
gravity wall with geogrid resisting the horizontal soil pressure. If the wall is not
battered back then the wall will tend to also add to the horizontal pressure if the
front settles just a small amount. Please modify accordingly.
2. The analysis submitted required the first block to be buried below grade 10.32
inches: The drawings only show 9" minimum which is not conservative. Please
modify accordingly.

3. It appears the geogrid is required for height exceeding 4' and not 7'. Please justify
with analysis. IBC 1806
