Seattle neighborhood evidence

Stevens

Review Stevens slope and slide mapping, open work-type pages, and compare six companies through eight selected Seattle permit records.

What the Stevens page brings together

This page is the neighborhood hub. It starts with Stevens rather than a single construction method: mapped terrain context, the work descriptions found in selected permits, and the companies attached to those records all appear in one place.

The evidence does not establish which company is best or currently works in Stevens. It gives a homeowner a more useful starting point than a name-only directory by preserving legal identity, registration context, permit counts, dates, locations, and exact public descriptions.

Slope, slide, and drainage context in Stevens

Seattle's neighborhood aggregate maps 9.77% of the Stevens boundary as steep slope and 15.11% as potential slide area. Liquefaction overlap and historical slide-event points also occur within the matched boundary. These layers identify questions to investigate; they do not diagnose a wall or classify an individual parcel.

For wall work, useful site questions include how grade changes across the lot, whether runoff concentrates above the wall, where subsurface drainage can lawfully discharge, and whether access or a nearby structure limits excavation and temporary support.

9.77%Steep slope
15.11%Potential slide area
0.5%Known-slide affected property
8.76%Liquefaction-prone area

The matched neighborhood boundary contains 41 historical known-slide event points across source years 1927, 1928, 1930, 1934, 1935, 1942, 1948, 1957, 1965, 1970, 1974, 1986, 1990, 1994, 1997, 1999, 2002, 2018. Points may be incomplete or generalized and do not establish a current condition at a nearby property.

What to verify for a Stevens wall project

  • Whether distress is limited to the wall or connected to a foundation, slope, drainage, or erosion condition.
  • Whether the existing assembly is a structural retaining wall, a rockery, or multiple systems that need separate scopes.
  • The mapped ECA status, survey geometry, property-line constraints, utilities, and current SDCI pathway for the address.
  • A maintainable drainage route and a construction sequence that protects adjacent improvements.
