Outside of the approach slabs, our plan is to go ahead and shift the street lighting over toward the street. I do not believe that any sidewalk extension is needed for the retaining wall. In the Bella Lane package, we are planning to continue the sidewalks up to the approach slabs. Let me look at the two items just to make sure and I will send you a couple of preliminary Bella Lane sheets for your reference. Would you mind sending us some preliminary sheets for the retaining wall for coordination? Joel A. Massey Project Manager icon Consulting Engineers, Inc. Bicentennial Financial Center 250 W.

First, will there be any street lighting that will need to be installed along the wall? I didn't see any in the CAD files you recently sent to us (7/20), but I wanted to confirm that with you. Second, will we need to include any sidewalk adjacent to the retaining wall? I don't think it will adversely affect anybody if we don't add the sidewalk at this time. However, since Icon is the EOR for Bella, I thought it best to ask you that question. Eric Eric S.
