Retaining wall construction in Greenwood
Compare three active companies across three Greenwood retaining-wall records, with completed-versus-issued status and adjacent-site context.
Three exact license matches, but not three equivalent completed examples
The selected Greenwood records connect three active Washington contractors to three retaining-wall scopes. Sage And Stone and Armas Concrete have Completed records in this slice. Groundworks appears on issued permit 7080716-CN, which is not presented as completed work. Each detailed Seattle Services Portal record displays the same Contractor License number as the company’s L&I registration at the September 13, 2026 review.
The Armas and Groundworks permit points are adjacent in the public data and the later record describes repair beside an existing residence. They may represent related site history, so the page does not present them as two independent demonstrations of completed experience. The permit numbers, dates, contractors, scopes, and statuses remain separate.

Neighborhood-specific context
Driveway loading, adjacent records, and Greenwood screening context
The neighborhood aggregate maps 1.88% steep-slope overlap, no potential-slide or known-slide-affected-property polygon overlap, 8.08% liquefaction-prone-area overlap, and three historical event points. A low neighborhood percentage is not parcel clearance; the address and proposed excavation still need current map and site review.
One completed record places the wall along a driveway and includes removal of the existing wall. That raises vehicle surcharge, edge protection, demolition, access, paving restoration, and drainage questions that a general wall scope may not answer. If a later repair record concerns the same or an adjacent site, bidders should review the earlier approved drawings and inspection history rather than treating the wall as context-free work.

7080716-CN · Issued · issued Dec 1, 2025 · Greenwood · $6,000Official Seattle record ↗Questions raised by these local records
- Does a driveway impose vehicle surcharge or edge-protection requirements that are included in the wall design and price?
- Are the issued repair record and earlier completed replacement record related, and what do the approved drawings and inspection histories show?
- Who owns demolition, hauling, temporary support, paving, drainage, utilities, guards, and final restoration?
- Does the actual parcel intersect ECA or liquefaction mapping despite the neighborhood-wide percentages?
- Can each company explain its role in the cited permit and provide a comparable completed reference where the page shows only an issued record?
