A dedicated Kidder Mathews team to source and negotiate the office, warehouse, and industrial-yard leases supporting the Elliott West and Mouth-of-Duwamish projects — at no cost to the County, with the market knowledge to move fast and the process discipline to clear Council.
The WTD capital program requires multiple leases — office, warehouse, and industrial outdoor storage — in the Duwamish and Interbay corridors to house teams, materials, and equipment through construction and commissioning. The County needs a single, accountable tenant-rep team to run every lease start to finish.
Each tab answers a piece of the assignment: the Space Program we'll deliver, the Market we'll draw on, our Approach and schedule, relevant Experience, the Team, and the Fee (there is no cost to the County). Our formal written proposal accompanies it.
The capital program needs distinct but linked spaces. We'll run them as one coordinated search so timing, geography, and budget stay aligned across every lease — and so the County has a single point of accountability.
Project, engineering, and construction-management staff. Priorities: efficient floor plates, parking ratio, transit access, term flexibility, and a fit-out timeline that supports 2027–28 occupancy.
Covered storage for materials, parts, and equipment. Priorities: clear height, dock & grade loading, power, secure access, and proximity to the two project sites.
Paved, secured laydown for pipe, equipment, and staging — the scarcest and most specialized asset class in the corridor, and a Kidder Mathews specialty.
Sufficient parking for field and office staff and fleet, coordinated across the office and yard sites so crews and vehicles are where the work is.
Office and warehouse are attainable in this market with the right relationships. Secured industrial outdoor storage adjacent to the project sites is the genuine scarcity — very little exists and almost none is openly marketed. Sourcing it is exactly what our industrial and IOS practice does, and it will drive the search strategy.
The search geography maps directly to the two projects: the Duwamish / SODO corridor to the south and the Interbay corridor to the north. Both are among the tightest, most contested industrial submarkets on the West Coast — which is precisely why an owner-relationship-driven search wins.
Schematic — relative positions, not to scale. Search boundaries refined with the County during the strategy phase.
An ~8-acre treatment-station site at S Spokane St & 1st Ave S, anchor of a ~$3.4B CSO program. The long, large program — and where our current availability is deepest. We center the SODO/Duwamish search on this site.
The existing wet-weather station (operating since 2005) now being upgraded, in Interbay near Elliott Bay. We anchor the north search here and canvass Interbay / Magnolia-edge / Ballard for office, warehouse, and yard.
These are construction and commissioning programs — the office, warehouse, and yard need to sit close to their site so crews, materials, and equipment are where the work is. That's why we run two anchored searches, not one city-wide sweep.
Seattle close-in industrial has run structurally tight for years, with limited new supply and constant pressure from logistics, maritime, and construction users. Quality space leases on relationships, often before it's marketed.
Industrial outdoor storage / laydown is the rarest asset in the corridor — shrinking as land redevelops. Securing it near the project sites is the single most important, and hardest, part of this assignment.
Rents, parking, access, and jurisdictional costs vary block to block across SODO, Georgetown, South Park, and Interbay. We map the trade-offs so the County's dollars and schedule go furthest.
Illustrative recent transactions and current asking rents from market data; specifics confirmed during the engagement. Party names withheld.
A live inventory of available and off-market office, warehouse, and yard space across both corridors, current asking and effective rents, and direct relationships with the owners who control it. We'll deliver a current-market survey during the strategy phase — this platform frames the approach and previews the availability.
To show what our market command means in practice, here is a curated sample of space currently available in the corridor that fits the program — office, warehouse, and the scarce secured yard. This previews our approach; a formal, verified current-market survey is delivered during the strategy phase.
Options are grouped by the two project clusters and by use. Each carries our initial posture — Tour, Hold, or Pass. Sizes and rates reflect recent market data and are subject to verification; we present space unbranded and confirm rate, availability, and terms directly with ownership before any tour.
Every option below sits within roughly a mile of the WWTS site at S Spokane St & 1st Ave S — the SODO/Duwamish industrial core, walking distance to the program's largest capital project.
Interbay / Ballard close-in industrial is among the most supply-constrained submarkets in the region, with very little openly marketed and most space trading on relationships. We'll run a dedicated Interbay canvass — office, warehouse, and yard near the Elliott West site — during the strategy phase and add those options to this survey. Being relationship-driven there is exactly where our team's owner network earns its keep.
Even a first pass shows real, program-fit space — including combined office + warehouse + yard sites and genuine secured laydown — available now in the Duwamish. That is the difference between a firm that claims the market and one that already works it every day.
A repeatable methodology built for public-agency work: rigorous up front, fast in the market, and structured so every lease clears Council cleanly and lands on schedule.
Confirm the program with WTD — space types, sizes, adjacencies, budget, and schedule for each project. Define search geography and success criteria. Deliver a market survey of available and off-market options in both corridors.
Canvass on- and off-market space, prioritize the scarce yard/IOS, and tour a curated shortlist. Provide a side-by-side comparison — rent, term, condition, parking, access, and total occupancy cost.
Run competitive negotiations to drive rate, concessions, and flexible terms. Manage LOIs and lease drafts on the County's fast turnaround expectations, coordinating with County counsel and risk.
Package each transaction for Council — fair-market documentation, business terms, and the record needed for authorization. We build the process into the schedule from day one so it never becomes the bottleneck.
Coordinate lease execution, fit-out timing, and commencement across the multiple leases so the program is in its space when the work demands it.
One senior-led team across all leases — no handoffs, no gaps between the office, warehouse, and yard searches.
Open reporting on options, economics, and compensation — everything documented for the public record.
Structured to hit ~5-day document turnarounds and a 2027–28 occupancy without cutting corners on diligence.
Representative Kidder Mathews industrial tenant-representation and advisory assignments that map to this program — public-agency clients, multi-space requirements, and the scarce yard/IOS product this search hinges on. A full transaction schedule accompanies our formal proposal.
We currently advise a Puget Sound public utility sourcing several acres of secured industrial staging in this same corridor to support a capital project — the same client type, geography, and asset as this assignment.
Represented a national user on a 120,000–140,000 SF warehouse-plus-yard requirement — sourcing, touring, and negotiating combined building and outdoor-storage space, exactly the mix this program needs.
Active leasing and advisory on secured yard / IOS along the Duwamish — the corridor and asset class at the center of this search, where most availability never reaches the open market.
Ongoing representation of manufacturing and storage users on requirements from ~35,000 SF with yard up to ~200,000+ SF — the site-selection, comparison, and negotiation discipline this assignment demands.
Firm-wide work with public port authorities and municipal agencies on ground leases, dispositions, and valuation — fluency in public process, fair-market standards, and governing-body approval.
Experience running multiple simultaneous leases and multi-building programs with unified reporting — the coordination this two-project, multi-lease assignment requires.
Public-sector and industrial-tenant references — including agency clients we've represented on comparable requirements — are provided with our formal proposal and available on request.
The people who pitch are the people who do the work. A senior-led team backed by Kidder Mathews' research, valuation, and lease-administration platform — one accountable group across every lease.
That structure means the County gets independent, conflict-managed counsel from senior local experts — backed by the research, valuation, and management depth of a major regional platform.
Our services are compensated by the landlord on each lease, consistent with standard tenant-representation practice — with full transparency and no cost to King County.
We welcome an interview to meet the team and walk through our approach in detail.
Confirm the program with WTD and deliver an initial market survey of both corridors within weeks.
Begin sourcing and touring — prioritizing the scarce yard/IOS — toward 2027–28 occupancy.
