Seattle neighborhood evidence

East Queen Anne

Compare five companies across five selected East Queen Anne retaining-wall permits, with official slope, slide, drainage, and permit context.

What the East Queen Anne permit set actually contains

The selected set contains five permits tied to five different active companies. The scopes are not interchangeable: one describes replacing an existing wall together with site stairs; another combines walls with a patio and landscaping; another combines landscaping with retaining walls and records a later wall revision; the remaining two use broader new-wall or site-wall language.

That spread is useful when assembling a bid list because it separates a documented replacement from general wall construction and landscape-integrated work. It does not establish current availability, quality, price, or experience with the conditions at a new address.

Official neighborhood screening

East Queen Anne slope history without turning a map into a parcel diagnosis

The neighborhood aggregate maps 16.22% steep-slope overlap and 17.38% potential-slide-area overlap. It also places 49 historical known-slide event points inside the matched neighborhood boundary. These are screening signals across a generalized area, not findings about every East Queen Anne property.

Seattle's historical Landslide Study separately describes an East Queen Anne Stability Improvement Area on the east-facing slope generally between Dexter Avenue N and Westlake Avenue N. The study discusses past instability, cuts and fills, groundwater or seepage, and drainage control in that defined subarea. A site elsewhere in the neighborhood cannot inherit those conditions by name; use the address, survey, current ECA mapping, and project-specific investigation.

The matched neighborhood boundary contains 49 historical known-slide event points across source years 1919, 1925, 1926, 1932, 1933, 1934, 1954, 1957, 1961, 1969, 1970, 1972, 1977, 1978, 1982, 1983, 1986, 1997, 1999, 2000, 2017. Points may be incomplete or generalized and do not establish a current condition at a nearby property.

Questions raised by the East Queen Anne evidence

  • Does the address fall inside a mapped ECA or the specific east-slope area discussed in the historical City study, and what current SDCI determination applies?
  • If stairs, patios, paving, or landscaping are part of the project, are their elevations, loads, drainage, guards, and restoration coordinated with the wall drawings and price?
  • How will demolition or excavation protect soil, utilities, neighboring improvements, and any public right-of-way used for access or staging?
  • Where do surface and subsurface water go, which approved drawings control the outlet, and who owns side-sewer coordination and inspection?
