About this opportunity
The U.S. Army Corps of Engineers, Seattle District, is preparing to procure GIS mapping and tree inventory services for the Lake Washington Ship Canal botanical garden, with a sources sought announcement closing May 26, 2026. The procurement is anticipated for total small business set-aside, though the final solicitation may be unrestricted if insufficient qualified small business responses are received.
Work is performed at the Carl S. English Jr. Botanical Garden, 3015 NW 54th Street, Seattle, Washington 98107. The contractor must deliver a comprehensive GIS inventory of all trees and select large woody shrubs across the 17-acre garden within 30 days of contract award. Deliverables include a fully editable spreadsheet with accession number, common name, botanical name, diameter at breast height, dripline radius, tree protection zone radius, and condition rating (1–6 scale) for each specimen; an interactive GIS-based Google Earth file in KMZ format with each tree linked to corresponding inventory data; and editable data files designed for long-term tracking of plant collection changes, specimen additions or removals, and condition rating updates. All deliverables must be fully editable with zero deviation from standards during final review.
The contract vehicle is firm-fixed-price. NAICS code 541370 (Surveying and Mapping except Geophysical Services) applies, with a small business size standard of $19 million. PSC code C211 (Architect and Engineering–General: Landscaping, Interior Layout, and Designing) applies.
The sources sought announcement is for market research only and does not constitute a request for proposals or commitment to award. Responses will inform the Government's acquisition strategy for the formal solicitation, which will be published separately on SAM.gov.
