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.
From permit to comparison
Completed East Queen Anne wall cases in detail
Each case connects a public construction permit to its displayed contractor license and an L&I registration check. Application answers describe the submitted project; they are not independent site findings. Completed status and an inspections-completed date do not certify workmanship, present condition or responsibility for every trade.

How to use this comparison
Ask how the wall and stairs are coordinated with access, grades, temporary support, drainage and any required right-of-way work. Compare bids against the same drawings and responsibilities.
What remains unknown. The short record does not establish the wall system, dimensions, drainage outlet, or which trades the contractor performed. Application answers are declarations, not an independent ECA or permit determination.
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.

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?
