NOTES TO THE DESIGNER:
* L1,L2,W1, AND W2 DIMENSIONS FROM FIGURE 3-5. MAXIMUM DEPTH (H1) FOR THIS TABLE IS 8'0"
** PRINCIPAL REINFORCEMENT WILL SPAN THE SHORTER DIMENSION
REINFORCED CONCRETE DESIGN IS BASED ON THE FOLLOWING:
1. LOADS : 200 psf SURCHARGE ADJACENT TO VAULT.
2. SOIL PROPERTIES = MOIST = 120 pcf WATER TABLE 2' BELOW SURFACE
SATURATED = 125 pcf BEARING CAP. = 1500 psf. MIN.
Ko = .80
