We too live, work and play in the area and have a vested interest in leaving the community better than when we found it. We realize that potential traffic impacts will create an inconvenience for residents, business owners and patrons alike. You have our commitment that we will work closely with the community and local businesses to reduce these impacts as much as possible and eliminate them, when feasible.
