Hello, my name is Terry and I am a help expert in the building and construction field. I will do my best to answer your question. Building codes require that there be a minimum cover over reinforcing bar used to keep concrete in place. The size of bar used for your porch may vary depending on your porch size, location and local code requirements. The cover needs to be 3" minimum on any surface permanently exposed to earth or weather. The minimum cover is 1 ½" most other places. Using this as a base, you need 3" on the top surface 5/8" bar and 1 ½" below if the porch is over a void and 3" if placed on dirt. Lets assume for model that this will be over a storage area or void below. Top + Bar + Bottom 3" + 5/8" + 1 ½" = 5 1/8" minimum If your bar is ½" then 5" will suffice. If your porch is over dirt then 6 5/8" will be needed. It is always best to verify CODE SPECIFIC information with your local Building Official and/or Building Department as local laws and codes do tend to vary somewhat from jurisdiction (town) to jurisdiction (town). I hope you have found this helpful! Terry CBO
