In the simplest terms, it means measuring to determine if the transportation network is adequate to accommodate the growth that is allowed by zoning and regulations. Transportation Concurrency is related to, but different than, Transportation Impact Studies and Transportation Impact Fees.
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 a six-year time period. Bellingham has adopted BMC 13.70 Multimodal Transportation Concurrency to meet this State law requirement.
Bellingham’s Multimodal Transportation Concurrency Program features multimodal level of service (LOS) standards and performance measures that include sidewalks, bike lanes, WTA transit, multiuse recreation trails, as well as automobiles, and is designed to help the City achieve Comprehensive Plan Transportation Element goals directing infill growth primarily to Urban Villages and to help complete sidewalks and bicycle lanes throughout the City.
Bellingham’s innovative Multimodal Transportation Concurrency Program received the 2009 American Planning Association /Planning Association of Washington Award for Transportation Planning in Washington State.
The Transportation Report on Annual Concurrency (TRAC) is the City's annual assessment of transportation concurrency status on the citywide multimodal transportation network. The primary objective of the TRAC is to provide an assessment of the existing multi-modal transportation system, which establishes the baseline level of service (LOS) and transportation concurrency conditions through the year. Over time, the TRAC will also identify transportation concurrency problems, issues, and circumstances throughout the City so that transportation funding and mitigation strategies may be explored to effectively accommodate changing conditions and circumstances. Ultimately, the goal of the TRAC is to provide an integrated link between Bellingham Comprehensive Plan land use and transportation policies and funding decisions for the City's annual Six-Year Transportation Improvement Program (PDF).
Bellingham’s Multimodal Transportation Concurrency Program (BMC 13.70) 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 and has been featured in a wide variety of State and national publications, as listed below, and in numerous State, national, and international planning and engineering conference presentations as listed on the awards page.
