All development projects in the City of Spokane Valley are subject to some level of traffic review. For small projects the review may be restricted to questions regarding location of access points. Larger projects often require a Traffic Impact Analysis (TIA) covering a larger area and/or Public Traffic Meetings.
When reviewing the traffic impacts of new development, the City of Spokane Valley follows the guidelines established by the Washington State Growth Management Act and Washington State Department of Ecology Environmental Policy Act.
The City's standards for traffic impact analysis are outlined in Chapter 3 of the Street Standards, which was adopted in 2009.
