30.66B.310 Road system impact fee.
(1) A development shall mitigate its impact upon the future capacity of the road system by paying a road system impact fee reasonably related to the impacts of the development on arterial roads located in the transportation service areas impacted by the development, at the rate identified in SCC 30.66B.330 for the type and location of the proposed development. A development’s road system impact fee will be equal to the development’s new average daily traffic (ADT), as determined by the department of public works’ administrative rules, times the per trip amount for the specific transportation service area identified in SCC 30.66B.330, except that the following adjustments may be made:
(a) In accordance with RCW 82.02.060(4), the director of public works shall have the authority to adjust the amount of the impact fee to consider unusual circumstances in specific cases to ensure that impact fees are fairly imposed;
(b) In accordance with RCW 82.02.060(5), the director of public works shall have the authority to adjust the amount of the impact fee to be imposed on a particular development to reflect local information when available, including studies and data submitted by the developer; and
(c) Adjustments will be made for trip reduction credits approved under SCC 30.66B.640 through 30.66B.650.
(2) As required by RCW 82.02.060(3), credit against a development’s road system impact fee shall be provided for dedication of land for, improvement to, or construction of any capacity improvements that are identified in the transportation needs report as part of the road system impact fee cost basis and are imposed by the county as a condition of approval.
(3) As provided for by RCW 82.02.060(2), exemption from road system impact fees may be provided for low income housing and other development with a broad public purpose, provided that the road system impact fee for such development is paid from public funds other than impact fee accounts. The developer requesting the exemption shall be responsible for identifying the source of and securing the availability of such public funds.
(4) Developments which are determined to cause a greater reduction in ADT on the road system than the number of new ADT generated by the development, by promoting the use of transit or other means, will be determined to generate no new ADT for the purpose of determining the development’s road system impact fee.
