GENERAL NOTES
Specifications:
-Revisions thereof and additions thereto and
Special Provisions for Materials and Construction
Concrete:
Earth pressure calculated based on Coulomb Theory.
All structure concrete shall be Mix. No. 3 (3500 psi) except
as noted below under reinforcing steel.
Reinforcing Steel: Reinforcing steel shall conform to A 615, Grade 60. All
splices, not shown, shall be lapped as per Bar Lap Charts.
Minimum cover for any bar shall be 2’’ unless otherwise
noted, with the exception of bars at the bottom and sides of
all footings which shall have 3’’ minimum cover.
Design Parameters:
Angle of Internal Friction:
33 degrees for excellent soil
30 degrees for good and poor soils (and all walls on pile footings)
7/8/83
7-16-02
Reinforcing Steel Design: fy = 60.0 ksi.
For Wall Types E and F, passive earth pressure from top
of footing to bottom of shear key was utilized in the design.
In these cases, the top of footing shall have a minimum of
30’’ cover.
Safe bearing pressures are factored resistances.

If the front face of a retaining wall less than 10 feet from
the edge of paved surfaces, epoxy coated reinforcement shall
be used in the front face of the stem and Mix. No. 6 (4500 psi)
