REF.: 1.) Florida Building CodeSection 1819.7
2.)Soil report from assumptions.
Soil is a loose brown to medium grain sand
lateral pressure = 150 psf Table 1819.6
Per Section 1819.6.1, Lateral pressure may be increased
by two times the value = 300 psf
Section 1819.7.2.1, Unconstrained

Where: A = 2.34P/(S1 b)

d = DEPTH 7.0 FT
b = Diameter of hole = 12" 1.00 F1!
S1 = SOIL PRESSURE = 2* SP*d/3 700.0 PSF
P =ACTUAL LATERAL LOAD 189.40 LBS
h = DISTANCE FROM LOAD TO GROUND LINE = MN 17.7 FT
SOLVE FOR "A" A = 2.34P/(S1b) 0.63
d = 0.5A[1+[1+(4.36h/A)]"0.5] = 2.64 FT < 7.0
Embedment depth of 7'-0" meets code.
Auger a 12"diameter hole and set pole 7' embedment depth then back fill
with natural soil and tamp in 6" lifts to achieve compaction.
Pole are flattened at the bottom for torsion resistance
