Roads & Drainage Notes:
1. The streets to be constructed for this project are subject to the Department of
Transportation Certification Program and Quality Management System
Maintenance Version Requirements. The Contractor, at his expense, shall provide
test results on 1) Subgrade, 2) Base and 3) Pavement. The Contractor shall insure
that all construction and testing is performed in accordance with the N.C.

Management System Maintenance Version", and shall report the testing and /or
core locations, test method, results and D.O.T. allowable range or tolerance, as
applicable. Subgrade shall be tested for density and shall be proofrolled by the
testing Engineer or the Engineer or Surveyor who will issue the Final Certification.
Base and pavement shall both be tested for density and thickness. If Parker &
Associates is administering the construction they must also proof roll the stone.
Twenty-four (24) hour advance scheduling before proof roll. Testing for pavement
shall be certified by either a professional Engineer or properly certified QMS
technician and shall be in accordance with QMS criteria. €tequired thickness for this
project is as shown on the plans. Note that thickness for widening or turn lanes is
greater than that for internal streets.
2. Minimum Densities:
Subgrade 100%
Stone Base 100%
S 9.58 90q
119.00 92 %
B 25.00 92 %
3. Notify the Engineer or Surveyor, who will issue the overall Final
Certification, of all phases of Roadway Construction.
4. All metal used for any type of catch basin or inlet shall be produced in the USA.
5. A minimum sight distance of 10'X70' shall be maintained
along the right-of-way of all internal intersections.
6.20 foot radii at right-of-way intersections, 30 foot radii at
edge of pavement intersections.
7. All culverts under streets shall be reinforced concrete per North Carolina Department
of Transportation Specifications, unless otherwise specified and/or approved by the
Engineer and/or Department of Transportation.
8. All roads shall be public and built to NCOOT Standards.
9. There shall be no encumbrances within the NCDOT Right-of-way.
10. All materials and practices shall meet North Carolina Department
of Transportation Standards.

traps and sediment basins. The remainder and bulk of clearing is not to be done until installation of these
items has been completed-
C. Sediment control measures are required to be installed at the earliest practicable date after start of
work Grading operations shall begin at tow points, points of outfall release or at other locations of where
sediment control measures are shown on plan, and the sediment control devices (silt fences, sediment
traps, sediment basins, etc.) shall be installed before or simultaneously with the grading of any area
draining to the device.
D. Install stabilized construction entrance prior to beginning construction.
E_ Clear and grub entire project area.
F. Install silt fence, sediment traps and sediment basins.
G. Rough grade and temporary seed areas not to be disturbed during street and utility construction.
H. Install Swales
I. Install storm drain pipes and outlet protection.
