Seattle ECA layers in Loyal Heights
0.16%Steep slope
0%Potential slide area
0%Known-slide affected property
0%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 0 known-slide initiation points inside the matched boundary. No usable event year was present for these matched points.
Points are historical records and may be incomplete or generalized. They do not state the current condition of a nearby property.
What the Loyal Heights 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 2022 through 2024. The median positive declared cost is $43,810 among the 2 records that report one. A declared permit cost is not a bid, invoice, final price, or neighborhood estimate.

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.
