I had not received a response so I phoned again this morning. Given I was unable to reach you this morning, I thought it best to follow up via email. Please note I have copied Steve Pfeifer, the contractor for the wall construction and the person who originally requested the inspection. Under the Result Comment section of the inspection receipt, there are several items mentioned. 1. USA erosion final required: Neither Steve nor I are clear as to what is required. Please advise. From whom do we get this? 2. Engineer sign off required — special inspection final: Attached site review document from engineer David Hall should address this item. 3. Summary letter required: Attached site review document from engineer David Hall should address this item. 4. Note: Fencing being done at time of inspection: Why is this relevant? It is my desire to close out this permit ASAP. Please advise what additional information is required to do so.
