1 OFA Dear Colleague letter on Rescinding guidance concerning waiver and expenditure authority under section 1115 of the Social Security Act Published: August 30, 2017. The U.S. Department of Health and Human Services (HHS) is committed to helping low-income families transition from welfare to work.
We added a front porch to our house that is 36 feet long and 8 feet 3 inches wide. One thing that I think people tend to overlook - but what some posters have stated - is how much useable space is taken up by porch posts/columns and railings.
The porch also has 9 linear feet of 6 step. So enter in the footing calculator, 6 depth by 12 width (always figure steps with a 12 width) by 9' length. This totals .17 cubic yards. The total concrete needed for the 3' by 3' porch will be .28 cubic yards.
