Cody,
If the trees are expected to be 8-10 ft diameter then the row spacing has to be greater than 8-10 feet for air, light penetration and access. the row spacing is usually 2 times or greater, than the plant spacing. If they will be pruned and shaped then the spacing may be fine. North/South is preferred orientation, but in my case the espalier fig orchard is on a south facing slope, so the rows have to be East/West, but sunshine is available for 8-10 hours per day in summer.
Apple Tree Spacing
"Row spacing width.
North/South direction; 1.3 times expected or projected tree height.
(For East/West row direction, use 1.5.) Tall Spindle limited to 10 ft. height."
This is a general "rule of thumb" but can be applied to almost anything that is grown in rows. The apple tree spacing above is used for newer commercial intensive orchards. With additional pruning (work) the figs can be planted closer, apple trees pruned to "Spindle" are planted at 4-1/2 feet in the row.
Good Luck and keep us posted.
