Construction Specifications
1. Aggregate size - Use 2-3 inch washed stone
2. Length - As effective, but not less than 50 feet.
3. Thickness - Not less than six (6) inches.
4. Width - Not less than full width of all points of
ingress or egress. Minimum of 12'.
5, Install filter fabric under entire footprint of the construction entrance.
6. Washing - When necessary, wheels shall be cleaned to
remove sediment prior to entrance onto public right-of-
way. When washing is required, it shall be done on an
area stabilized with crushed stone which drains into an
approved sediment trap or sediment basin. All sediment
shall be prevented from entering any storm drain, ditch,
or watercourse through use of sandbags, gravel, boards
or other approved methods.
7. Maintenance - The entrance shall be maintained in a
condition which will prevent tracking or flowing of
sediment onto public rights -of -way. This may require
periodic top dressing with additional stone as conditions
demand and repair and/or deanout of any measures used to
trap sediment. All sediment, spilled, dropped. washed or
tracked onto public rights -of -way must be removed

SECTION A: SELF -INSPECTION
Self -inspections are required during normal business hours in accordance with the table
below. When adverse weather or site conditions would cause the safety of the inspection
personnel to be in jeopardy, the inspection may be delayed untR the next business day on
which it is safe to perform the inspection. In addition, when a storm event of equal to or
greater than 1.0 inch occurs outside of normal business hours, the seff-inspection shall be
performed upon the commencement of the next business day. Any time when inspections
were delayed shall be noted in the Inspection Record.
