Retaining wall construction in East Queen Anne

Four companies, four materially different construction contexts

The selected records connect four active Washington contractors to four Completed East Queen Anne permit records: 6810013-CN, 6880866-CN, 6950724-CN, and 6865414-CN. Expired Quercus permit 7028656-CN remains visible on the broader neighborhood profile but is excluded from this service intersection. On September 13, 2026, the detailed Seattle Services Portal record for each included permit displayed a Contractor License number that exactly matched the company’s active Washington L&I license.

Those distinctions matter before requesting bids. A company associated with a broad wall permit should not automatically be credited with a specific structural system, and a landscape-integrated permit is not automatically comparable to a constrained replacement. Open the exact record and ask the company to explain its role, design team, wall system, access, drainage, inspections, and changes.

Neighborhood-specific context

Construction questions shaped by East Queen Anne’s east slope

The neighborhood aggregate maps 16.22% steep-slope overlap, 17.38% potential-slide-area overlap, and 49 historical known-slide event points. The City’s historical Landslide Study also defines an East Queen Anne Stability Improvement Area on the east-facing slope generally between Dexter Avenue N and Westlake Avenue N. That defined subarea is useful context, not a diagnosis for every address carrying the neighborhood name.

For a site near the east slope, bids should follow the same survey and approved design and should state excavation limits, temporary support, soil and groundwater assumptions, access, protection of neighboring improvements, erosion control, permanent drainage, and the lawful outlet. Patio, stair, driveway, and landscape elevations should be coordinated with the wall rather than left as disconnected allowances.

Questions raised by these local records

• Which wall system and dimensions were approved, and are bidders pricing the same structural, geotechnical, civil, and landscape documents?
• Does the actual address intersect an ECA or the defined east-slope study area, and what current SDCI review applies to this proposal?
• How will excavation, temporary support, equipment, exported soil, utilities, trees, and neighboring property be handled on a constrained slope site?
• Where will surface and subsurface water discharge, and who owns side-sewer review, inspections, and maintenance details?
• When stairs, patios, or landscaping are included, are their elevations, loads, guards, drainage, finishes, and restoration included in one coordinated scope?
