Sample Residential Construction Sequence
1. Submit a Land Disturbing Permit Application at least 30 days prior to any land disturbing activity
occurring.
2. Organize pre -construction meeting with Chatham County Watershed Protection Department to
review site plan prior to land disturbing activities. Land -Disturbing Permit and Approved Plans
will be provided at this meeting.
3. Install all temporary erosion control measures according to the information discussed during the
pre -construction meeting. Minimal clearing may occur in the immediate area of all measures to
provide for installation.
4. Permitted land disturbing activities may begin once measures are installed.
5. Complete self -inspections weekly and within 24 hours or a 0.5" or greater rainfall event.
6. Maintain all erosion and sediment control measures in good working order. Silt fence, inlet
protection and other similar measures must be cleaned out when they are half full. Clogged silt
fence outlets must be refreshed/replaced. Silt fence cannot have holes or tears.
7. Ground cover shall be provided as follows:
a. Stabilize basins with ground cover immediately after installation. (If applicable)
b. Stabilize diversion ditches intended to be in service for (14) days or more with
temporary seeding and erosion control matting. (If applicable)
C. For all areas of moderate and/or steep slopes, stabilize area with seed and matting if
the slope has not been disturbed for a period of (7) days.
d. Provide ground cover sufficient to restrain erosion on any portion of the site upon
which further land -disturbing activity is not being undertaken within (14) calendar days
of temporarily or permanently suspending land disturbing activity.
e. Establish permanent ground cover sufficient to restrain erosion immediately following
completion of construction or development and/or prior to final inspection.
9. Re -install adequate erosion and sediment control measures and/or increase maintenance
frequency where approved measures fail to prevent accelerated erosion, off -site sedimentation,
or repetitive non-compliance issues.
10. Measures must be installed at the back of curb to restrict all vehicle access to the construction
entrance. All measures must be installed according to the approved plan unless approved in the
field by Chatham County Watershed Protection Department staff (approved Field Revision).
11. Modifications to the approved and permitted plans shall be approved, by Chatham County
Watershed Protection Department staff only, prior to removal or installation. Contact Chatham
County Watershed Protection Department staff to request an inspection and obtain a sign -off
on the plans or an approved Field Revision.
12. Once grading and construction activities are complete, temporary measures are removed, and
the site is stabilized call Chatham County Watershed Protection Division staff to schedule the
final inspection.
13. Once the final inspection is complete the permit will be closed and no additional ground
disturbing activities can occur.

5. Cover waste containers at the end of each workday and before storm events or provide
secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
7. Empty waste containers as needed to prevent overflow. Cleanup immediately if containers

4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet awayfrom storm drains, streams or
wetlands unless there is no alternative reasonably available. If 50 foot offset is not attainable,
provide relocation of portable toilet behind silt fence or place on a gravel pad and surround with
sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high foot traffic
areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize a licensed
sanitary waste hauler to remove leaking portable toilets and replace with properly operating unit.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least 50 feet away
from storm drain inlets, sediment basins, perimeter sediment controls and surface waters unless
it can be shown no other alternatives are reasonably available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of five feet
from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance with the
approved plan and any additional requirements. Soil stabilization is defined as vegetative,
physical or chemical coverage techniques that will restrain accelerated erosion on disturbed
soils for temporary or permanent control needs.
