B.

Requirements. Development above the thresholds in subsection 23.52.004.A shall contribute toward achieving the SOV reduction targets identified on Map A for 23.52.004, either based on location of the development in an urban center, hub urban village, or within one-half mile's walking distance of a light rail station, or where these locational criteria are not met, by selecting and implementing at least one mitigation measure from a list of measures identified in a Joint Directors' Rule adopted by the Directors of the Department of Construction and Inspections and the Department of Transportation.

(Ord. 127228, § 18, 2025; Ord. 125757, § 3, 2019; Ord. 124887, § 2, 2015; Ord. 117383, § 9, 1994.)

If a proposed use or development does not meet the LOS standards at one (1) or more applicable screenline(s), the proposed use or development may be approved if the Director concludes that an improvement(s) will be completed and/or a strategy(ies) will be implemented that will result in the proposed use or development meeting the LOS standard(s) at all applicable screenline(s) at the time of development, or that a financial commitment is in place to complete the improvement(s) and/or implement the strategy(ies) within six (6) years. Eligible improvements or strategies may be funded by the City, by other government agencies, by the applicant, or by another person or entity.

2.

Likely distribution of project traffic and effects on traffic operations;

3.

Availability and expected usage of transit;

4.

Existing vehicular, pedestrian, and bicycle conditions, including access and connections to transit and bicycle facilities; and

5.

Collision history.

C.

Impact mitigation. Based upon the results of the transportation impact analysis, the Director may condition permit approval, as a Type I decision, to mitigate or prevent transportation impacts.

1.

Except as provided by subsection 23.52.008.C.2, required mitigation may include, but is not limited to:
