CONSTRUCTION SCHEDULE
(INITIAL CLEARING, GRUBBING & MASS GRADING)
1. Obtain all permits before beginning construction.
2. Install gravel construction entrances at the locations show, then
install all silt fences around the perimeter of the construction area
and 5 feet off of the wetlands to the west.
3. Construct temporary skimmer basin #20 & #30. Maintain existing
skimmer basin #7.
4. Clear and grub, strip topsoil and construct all diversion berms,
check dams and armor the berms noted on the erosion control
plan with turf reinforcement matting.
5. Continue clearing and grubbing of the site as necessary.
6. Seed and mulch all completed diversion berms within 7 days of
their completion.
7. Continue mass grading the site while maintaining all erosion
control measures and diversion berms during the site's grading.
8. After completion of all site grading, re -spread topsoil, fine grade,
seed and mulch all disturbed area that will not be disturbed with
