King County, not Sammamish
King County context, not Sammamish figures
These are King County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Sammamish measurements.
- Establishments in King County70,376
- Employment at those establishments, King County1,305,947
- Covered employment, King County1,449,785
- Average annual pay, King County$132,279
- Average weekly wage, King County$2,544
- Housing units permitted, King County10,564

- County product change over the prior year, King County7.9 percent
- Average income of an arriving household, King County$117,917
Every figure in this section is published for King County as a whole and is not a measurement of Sammamish. It is here because a county backdrop is what a credit committee reads a place against, and it is labelled so that it can never be quoted as the place's own.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- This place is not listed as a community in the FEMA Community Status Book, so no NFIP participation or CRS class is shown.
- Parcel level detail, zoning and flood zone at an address are resolved in the platform, not on this page.
SBA figures count approvals to borrowers whose address is in the place. They are not approvals for projects inside the place boundary: the tape records a borrower city and a project county, and those can differ.

These count approvals to borrowers whose address is in Sammamish, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Sammamish borrowers get paid back?

Are the county figures on this page Sammamish figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for King County as a whole and there is no place level equivalent. They appear in one clearly marked section as context and are never presented as measurements of Sammamish.
Is zoning published for Sammamish?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
