3 active launch-set companies appear across 4 selected city permits, alongside official ECA layer aggregates.

Seattle ECA layers in Sunset Hill

15.04%Steep slope
15.24%Potential slide area
1.46%Known-slide affected property
16.47%Liquefaction-prone area

These percentages report mapped polygon overlap with the official Neighborhood Map Atlas boundary. A zero can mean no overlap in this generalized boundary; it does not certify that a parcel is outside every regulated or observed condition.

For a retaining-wall proposal, use the Seattle ECA and steep-slope wall guide to move from neighborhood screening to address research and a project-specific SDCI pathway.

Known-slide event points

The city layer places 38 known-slide initiation points inside the matched boundary. Source dates represented: 1933, 1936, 1937, 1949, 1950, 1953, 1955, 1956, 1960, 1964, 1970, 1974, 1977, 1982, 1983, 1984, 1986, 1987, 1997, 1999, 2001, 2019.

Points are historical records and may be incomplete or generalized. They do not state the current condition of a nearby property.

What the Sunset Hill permit filter establishes

A documented project connects a legal contractor identity to a short public permit description and this recorded neighborhood label. It is evidence of past work, not a current availability or service-area claim. Contractor evidence is published only after the neighborhood reaches at least two different active companies or three selected permits.

The current selected set spans 2021 through 2025. The median positive declared cost is $100,000 among the 4 records that report one. A declared permit cost is not a bid, invoice, final price, or neighborhood estimate.

Work descriptions found here

Keywords are matched only against the selected public descriptions. They do not infer materials or services that the permit does not name. A dedicated local page appears only when at least two companies clear the evidence threshold.
