T5._ Multi-modal concurrency
The Washington State Growth Management Act (GMA) (RCW 36.70A.030 (6) (b)) requires that needed transportation improvements or programs be in place concurrent with development or that a financial commitment exists to complete the improvements or strategies within six years. Multi-modal concurrency allows jurisdictions to spend the impact fees collected from new development to help cover the costs of growth on infrastructure supporting ways to get around besides roads.
The 2016 report for Olympia’s Multimodal Concurrency Scoping Project discusses a number of examples. Multi-modal concurrency is now part of the final draft of Olympia’s new Transportation Master Plan.
Bellingham’s Multimodal Transportation Concurrency Program (BMC 13.70) features multimodal level of service (LOS) standards and performance measures that include sidewalks, bike lanes, WTA transit, multiuse recreation trails, as well as vehicles, and is designed to help the City achieve 2016 Comprehensive Plan Transportation Element goals directing infill growth primarily to Urban Villages and to help complete sidewalks and bicycle lanes throughout the City. It was one of the first in the nation to move beyond traditional auto-oriented level of service (LOS) measurements to assess the adequacy of the citywide transportation network.
