The bill amends RCW 47.80.030 to enhance the requirements for regional transportation planning organizations in Washington State. It mandates that these organizations develop and periodically update a regional transportation plan in collaboration with various stakeholders, including the department of transportation and local governments. The updated plan must incorporate a least cost planning methodology, identify existing and planned transportation facilities, establish level of service standards, and include a financial plan for implementation. Additionally, it emphasizes the need for assessing regional development patterns and ensuring the efficient use of existing transportation facilities.

A significant addition to the bill is the requirement for regional transportation plans to provide for reductions in greenhouse gas emissions and vehicle miles traveled. This new provision applies specifically to regional transportation planning organizations that include counties meeting certain population density and growth criteria. The bill aims to promote sustainable transportation practices while ensuring that regional transportation systems are effectively integrated and responsive to the needs of the communities they serve.
