END OF SECTION C fv7'L Gn - ty ~ J Dear Mr. Webb: As requested, I have conducted a cursory review of the future O'Reilly Auto Parts store to be located on the northeast corner of Texas Avenue and Morgan's Lane. At this time, our Staff has the following comments regarding the plans: 1. What is this area? It needs to either be incorporated into the parking lot as a parking space or into the landscaped area. As shown, it will more than likely function as a parking space, and it will be difficult to maneuver out of it without a small back-out area where the dumpster is currently shown. 2. The dumpster cannot face Texas Avenue and gates are discouraged 3. The driveway on Morgan's Lane needs to be relocated into the shared access easement that is shown on the final replat of this property and the adjoining lot. Morgan's Lane is substandard but was upgraded with an asphalt surface as a condition of allowing the funeral home to access it. If the asphalt does not reach the access easement, then that portion of Morgan's Lane will need to be upgraded as well before a driveway will be approved. 4. You will need to provide a 180 square foot end island at the end of this parking row. 5. It appears that you may need an on-site fire lane unless all parts of the building will be within 150' of a public right-of-way. Make sure that the fire trucks can make these radius turns. 6. What is the "dealer door"? Will there be any auto servicing in the building? If so, specify where and how much space will be devoted to service bays. 7. Are there any trees within the first 24' of the property that are 4" caliper or above? If so, they must be retained and cannot be removed without prior approval. 8. Make sure that all perimeters of the parking lot are curbed. I understand that some of the above comments may result in a redesign of the site, and I look forward to your formal submission that incorporates these comments.
