(1) In determining whether or not a proposed development is concurrent, the department of public works shall analyze likely road system impacts on arterial units based on the size and location of the development.

(2) A concurrency determination is based on an evaluation of road system impacts for a proposed development within the boundaries of the development’s transportation service area. The evaluation will identify the development’s impacts on any arterial unit in arrears as specified in SCC 30.66B.160, or any arterial unit designated at ultimate capacity.

(3) A development’s forecast trip generation at full occupancy shall be the basis for determining the impacts of the development on the road system. The department of public works will accept valid data from a traffic study prepared pursuant to this chapter or will use the latest edition of the ITE Trip Generation report published by the Institute of Transportation Engineers. Adjustments will be made for trip reduction credits approved under SCC 30.66B.640 - .650.

(4) If a development is proposed within a transportation service area that contains no arterial units in arrears and/or designated ultimate capacity arterial units, then the development shall be determined to be concurrent, except that if the development generates more than fifty peak-hour trips, the requirements of SCC 30.66B.035 shall also apply.
