any discrepancies occur the requirements of the permit shall govern.
2. Construction inspection of all proposed roads within the development
will be made by the County. The contractor must notify the Department
of Engineering (296-5661) 46 hours in advance of the start of
construction.
3. All materials and construction methods shall conform to current
specifications and standards of VDOT. All excavation for underground

the contractor shall have CBR tests performed on the subgrade soil.
Three (3) copies of the test results shall be submitted to the County.
If a subgrade soil CBR of 10 or greater is not obtainable, a revised
pavement design shall be made by the design engineer and submitted with
the test results for approval.
6. All slopes and disturbed aces are to be fertilized, seeded and mulched.
The maximum allowable slope is 2:1 (horizontal: vertical). Where
reasonably obtainable, lesser slopes of 4:1 or better are to be
achieved.
7. Surface drainage and pipe discharge must be retained within easements
prior to acceptance by VDOT. All drainage outfall easements are to be
extended to a boundary line or natural watercourse.
8. Guardrail locations are approximate. Exact length, location and
appropriate end treatments will be field determined at the time�of
construction. Additional guardrail may be required at locations not
shown when, in the opinion of VDOT, the Director of Engineering, or the
Director's designee, it is deemed necessary, When guardrail is
required, it shall be installed four (4) feet offset from the edge of

sections, as shown on the typical pavement section detail, shall be
strictly adhered to. Exceptions will not be allowed.

19. A video camera inspection is required for all storm sewers and culverts
that are deemed inaccessible to VDOT inspections and are to be accepted
in VDOT's maintenance program and ownership. The video inspection shall
be conducted in accordance with VDOT's video camera inspection procedure
and with a VDOT and/or County inspector present. In addition, if high -density
