minimum lime stabilization requirements.

per your comment.
Storm Drainage Plan:
14. Due to the erosion concerns, we have decided to go with 12" gabion mattresses in lieu of
the rock riprap and filter fabric. In our opinion, gabion mattresses will help prevent
erosion over a longer period of time. Please let me know if this is acceptable to you.
15. A 6" crushed stone base on top of a filter fabric sub-base has been added to the headwalls
to reduce any shifting or damage to the storm drain system per your request.

check has been added within a 20' x 20' utility easement to each connection to the 10"
public water line along Belt Line Road. The previous DDC has been removed.
17. Additional gate valves have been added to the private 8" water line loop per your
comment.

20. Per our meeting on January 31st, the 10" water line has been moved further northeast in
front of Belt Line Trade Center Building "B".
21. The fire line layout is being reevaluated to incorporate the fire line lead-ins inside of the
building in lieu of outside per your comment. This will be shown as part of the MEP
plans for the building permit submittal.
