Recommended approach
On a consultation, identify which inquiries are intended for your SeaTac service area, which are outside scope and which require attorney review before any response or routing. Decide whether location is a qualification field, a routing rule, a reporting dimension or simply information for staff. Keep SeaTac, King County and any broader Washington service area distinct in your intake questions and reporting.
