No, these roundabouts were only conceptual in nature and are not required by the PUD. 7. Why are curbs not shown for the southern portions of this project? Is this for future parking lot expansions? Curbs are not shown for future expansions of the parking lot. 8. Is the north entrance on Illinois Street consistent with what is approved in the PUD? Yes, the northern Illinois Street entrance is consistent with the approved entrance in the PUD. 9. The southern private roads intersection should be changed to have a more generous curve, allowing for better site distance at this intersection. The intersection has been revised to show a larger radius on the north /south road. The stop bar has also been moved closer to the intersection that allows for better site distance. 10. Please indicate the existing and proposed right -of -ways on Illinois Street. The existing and proposed right -of -ways have been labeled on Illinois Street. 11.

The line -types have been labeled in the legends. If they are not labeled in the legends, they are labeled in plan view due to the limited number of line - types. 13. Why are curbs not shown around the CVS Pharmacy? City standards require curbing in all parking areas, except when disallowed for storm water quality treatment. The tenant prefers not to curb the sidewalk along the frontage of the store to allow for better maneuverability for customers with shopping carts.
