Fire likelihood alone (USFS's burn-probability figure) ranks Marietta-Alderwood at the 11th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
Marietta-Alderwood's building exposure, zone by zone
52.5% of Marietta-Alderwood's 2,009 buildings sit in USFS's Minimal exposure zone, with only 35.7% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself.

Shopping for coverage in Marietta-Alderwood
Marietta-Alderwood's low rating (10th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
What would actually reduce this score
With 52.5% of buildings rated Minimal exposure, Marietta-Alderwood gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
