Foundation Design
(OP)
I am attempting to design a small foundation for a light pole. The pole is 4" square and 25' tall and must with stand a 120mph wind. Need help please.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Foundation Design
The design involves considering the lateral forces on the pier and the desired amount of lateral deflection that can be tolerated. A geotechnical engineer can help with this in terms of allowable stresses on the soil and determining an appropriate soil modulus to measure its stiffness.
Your local municipality may also have some set standards for light poles, traffic poles, etc. that you could utilize.

Design foundation for resultant shear and bending forces such that foundation contact area is always under positive (compression) pressure over entire area.
Bearing capacity of coastal soils which are usually sandy is best determined by the standard penetration test (SPT) method. Care must be taken with the proximity of the water table.
