Regulatory Threshold

What is the regulatory threshold?

The regulatory threshold is the “trigger” for requiring compliance with the Basic Requirements of the SRSM. In the City of Spokane, the threshold is defined as the addition or replacement of any impervious surfaces. The regulatory threshold applies to the total impervious area replaced or added at full build-out. Refer to common plan of development or sale definition to determine whether your project will trigger the regulatory threshold.
