Welcome to Palouse RTPO

We are the Washington State Department of Transportation (WSDOT) funded and regulated  Transportation planning organization for the SE corner of the WA State. We serve four Counties of Asotin, Garfield,  Columbia and Whitman. Palouse RTPO was originally formed in 1993 between the four counties as a result of Growth Management Act (GMA) to ensure local and regional coordination of Transportation plans. (Learn More) We work closely with four counties, local and regional community, Public Transit Agencies, Ports, Cities, Towns, WSDOT and the Lewis-Clark Valley Metropolitan Planning Organization (LCVMPO) to deliver comprehensive transportation planning and policy services for the region.
