Where the only remedy to an arterial unit in arrears is the installation of a traffic signal, but signalization warrants contained in the current edition of the manual on uniform traffic control devices are not met at present, developments impacting the arterial unit will be allowed to proceed without the installation of the traffic signal; PROVIDED, That all other warranted level-of-service and transit related improvements are made on the arterial unit with the deficient level-of-service. Developments impacting such arterial units will not be issued building permits until the improvements (not including the traffic signal) to the level-of-service deficient arterial unit are under contract or being performed. Such developments will still be subject to all other obligations as specified in this chapter. (Added by Amended Ord. 02-064, Dec. 9, 2002, Eff date Feb. 1, 2003).
