Retaining wall replacement in Phinney Ridge
Compare two Phinney Ridge wall-replacement records: a concrete-to-Keystone block scope and reconstruction of retaining walls with a front-yard stairway.
Two replacement records, two materially different bid scopes
Permit 6957919-CN describes replacing an existing concrete retaining wall with a Keystone block wall. Permit 6898125-CN describes removing and reconstructing retaining walls and a front-yard stairway. The first names a replacement material; the second makes stairs part of the reconstruction but does not identify the wall system in the public description.
Neither short record supplies wall height, reinforcement, drainage, temporary support, survey limits, or the complete approved details. The comparison therefore shows documented scope differences and direct records rather than treating the two companies as interchangeable Phinney Ridge recommendations.

Neighborhood-specific context
Phinney Ridge replacement questions suggested by the records
The neighborhood aggregate maps 4.69% steep-slope overlap, 0.11% potential-slide-area overlap, 0.70% known-slide-area overlap, and four historical known-slide event points. Those values are broad screening context only; the replacement site needs its own address, survey, ECA, drainage, and excavation review.
The block-wall record raises questions about the exact proprietary system, reinforced-soil excavation envelope, leveling and bearing preparation, compaction, drainage aggregate, and outlet. The wall-and-stair record raises a different coordination problem: demolition sequence, stair and wall elevations, guards or handrails where required, surface drainage, and restoration should be priced from one approved set of documents.

6898125-CN · Completed · issued Aug 9, 2022 · Phinney Ridge · $20,000Official Seattle record ↗Questions raised by these local records
- What portions of the existing wall and footing are removed, and how is retained soil supported before the new system is complete?
- For the Keystone block scope, what system, reinforcement length, excavation width, bearing preparation, compaction testing, drainage, and outlet are shown in the approved design?
- For the wall-and-stair scope, are stair geometry, wall elevations, guards or handrails, drainage, finishes, and restoration coordinated rather than split into ambiguous allowances?
- Do property lines, utilities, trees, neighboring improvements, or public-right-of-way staging constrain excavation and equipment access?
