GRADING DESIGN:
10.1
Final Master Plan or Schematics. Include earthwork cut
and fill, surface drainage design, pavement grading, and
other spot elevations at critical design areas. Coordinate
surface grades with architectural, structural, and
mechanical design to provide proper surface drainage.
Storm sewer criteria is specified in the Sanitary Design
Criteria.
10.2
Consult soil classification data in the subsurface
investigation (geotechnical report), required by the
Structural Engineering Design Criteria.
10.3
Contours shall show grading of the entire project site.
Utilize spot elevations at buildings, critical areas, and other
site features for grading control.
10.4
Show any temporary (construction period) or permanent
erosion control.
10.5
Include on the grading drawings:
A.
Bench Mark location;
B.
Spot elevations at structure corners, entrances, all first
floor elevations of new buildings and, if appropriate, of
existing buildings.
C. Spot elevations of all walks and paved surfaces,
corners in parking lots, high and low points, top and
bottom of walls, steps, curbs, and other areas of grade
change.
D. Accessible routes used by people with disabilities.
E.
Flow lines/center lines of drainage ways with slope
gradient.
F.
Intake elevations of the storm drainage system. Show
all utility storm sewerage new work on "W" Drawings.
G. The established grading limits.
H.
The quantity of rock excavation, if required, for the site
grading.
I.
Non-utility shoring required by major site excavation.
