AN ORDINANCE relating to transportation concurrency; adopting a requirement to include an annual report and form an expert review panel to review transportation concurrency updates; and amending Ordinance 14050, Section 14, as amended, and K.C.C. 14.70.270.
body
BE IT ORDAINED BY THE COUNCIL OF KING COUNTY:
SECTION 1. Ordinance 14050, Section 14, as amended, and K.C.C. 14.70.270 are each hereby amended to read as follows:
A. The traffic model for concurrency shall be updated annually as part of the budget process or when authorized by the county council by ordinance. The update process shall include the most recently adopted roads CIP, updated traffic volumes and updated information regarding issuance of concurrency certificates, development approvals and development activity. The traffic model shall conform to the guidelines and procedures described by the Federal Highway Administration in its publication entitled Calibration and Adjustment of System Planning Models dated December 1990 or its successor. Each update of the traffic model shall be used to produce a new concurrency map and table of estimated vehicle trips for monitored zones. The concurrency map and table of estimated vehicle trips for monitored zones shall be submitted to council for its approval by ordinance. The updates of the traffic model shall be deemed adequate for the purposes of concurrency analysis and the concurrency map shall be used to determine the concurrency of proposed residential development projects. The traffic model shall be used to prepare the concurrency map and to perform site specific analysis for nonresidential projects.
B. An annual report shall be prepared by the road services division on the concurrency program update. The annual report shall explain the technical assumptions, land use changes, network changes and other parameters used to update the concurrency model. The annual report shall be submitted to the council along with the annual update required by subsection A. of this section. Eleven copies of the report shall be filed with the clerk of the council, who shall retain the original and shall forward copies to each councilmember and to the lead staff of the council's transportation committee, or its successor.
C.1. An independent expert review panel on concurrency shall be established to:
a. review the annual report on the concurrency model update; and
b. evaluate proposed changes to the transportation concurrency process and model developed by the road services division.
2. The panel shall be comprised of four to six persons and include representation from the development community, the environmental community, transportation planning professionals, the unincorporated area, the public at large and multimodal transportation interest groups. Each representative shall be appointed by the executive and confirmed by the council.
3. A summary of the panel's review of the annual report on the concurrency model update and its evaluation of proposed changes to the transportation concurrency process and model shall be included with the submittal of the annual report to the council.
D. The concurrency map is a result of the values inputted in to the traffic model, as described in subsection A. of this section. The concurrency map indicates if a concurrency zone does or does not comply with adopted TAM and travel time level of service standards. Any changes to the concurrency status of a zone or zones on the concurrency map other than those resulting from the model update process may only be accomplished by the council, through an ordinance, by changing any combination of the
adopted TAM or travel time standards, or the list of funded projects in the most recently adopted CIP.
