They had some literature on the desk for people to take, so I started looking through it. They had some standard retaining wall details. However, the steel in the stem was on the wrong face of the wall. I couldn't believe that they would hand out county standard retaining wall details with such basic errors. I talked to the building official about it, and he did not know where they got the standard details from, they had just been around for years. They did end up pulling the details, and I now think they are corrected. How this happened and why it took so long for someone to find the error is a little scary.
