1. Start with the Duvall service boundary
Duvall is recorded as a municipality in King County, Washington. The 2020–2024 American Community Survey 5-year population estimate for Duvall city is 8,526, with a margin of error of 32. That is geographic and eligibility context—not evidence of search demand, competition, legal need, lead volume or revenue. Your intake should therefore ask a more practical question: which visitors can your firm serve, and which inquiries should be directed elsewhere?
Recommended approach
Define the geographic language and routing rules before building questions. If your firm serves Duvall and other parts of King County, separate location eligibility from case qualification. Decide what should happen when a visitor identifies a location outside your service area, gives an incomplete address or needs a practice area your firm does not handle. Review those decisions with counsel before publishing the flow.
