Hello this is Melissa Cordell and Tony Sohl. We are apposed to the beeping signals you are requiring and the truncated domes. The domes mess up canes and wheelchair users or anyone who has to walk on them can slip and fall. I know if a sighted person who got hurt one time. Please e-mail us back. Thank you for taking the opportunity to look at this message. The reason why Melisssa is using my e-mail is because she can only type one handed.
