(1) The transportation element required by RCW 36.70A.070 may include, in addition to improvements or strategies to accommodate the impacts of development authorized under RCW 36.70A.070(6)(b), multimodal transportation improvements or strategies that are made concurrent with the development. These transportation improvements or strategies may include, but are not limited to, measures implementing or evaluating:

(a) Multiple modes of transportation with peak and nonpeak hour capacity performance standards for locally owned transportation facilities; and

(b) Modal performance standards meeting the peak and nonpeak hour capacity performance standards.

(2) Any county located to the west of the crest of the Cascade mountains that has both a population of at least four hundred thousand and a border that touches another state, and any city in such county, may include development of freight rail dependent uses on land adjacent to a short line railroad in the transportation element required by RCW 36.70A.070. Such counties and cities may also modify development regulations to include development of freight rail dependent uses that do not require urban governmental services in rural lands.

(3) Nothing in this section or RCW 36.70A.070(6)(b) shall be construed as prohibiting a county or city planning under RCW 36.70A.040 from exercising existing authority to develop multimodal improvements or strategies to satisfy the concurrency requirements of this chapter.

(4) Nothing in this section is intended to affect or otherwise modify the authority of jurisdictions planning under RCW 36.70A.040.
