The Tigard Triangle is the commercial wedge bounded by 99W (Pacific Highway), I-5, and OR-217, and every paving job in here is commercial work. There is effectively no residential paving demand inside the Triangle boundary -- the district is retail, light commercial, multi-tenant office, and a new wave of mixed-use development built under the Triangle Strategic Plan. The buyer profile is a property manager, a retail anchor's regional facilities lead, or a tenant-improvement general contractor for the new mixed-use builds. Cojo prices Triangle jobs the way commercial work in any high-traffic state-route-frontage market gets priced: with ODOT coordination on 99W, written night-pour windows, and traffic control built into the base bid.
Why the Triangle Reads as a Commercial Paving District
The Triangle's three boundaries each impose a different paving constraint. 99W frontage triggers ODOT right-of-way permits on any work that touches state-route pavement or driveway approaches, with traffic-control plan submission running 4 to 8 weeks ahead of the pour. The I-5 boundary along the southeast edge of the Triangle puts ODOT interchange right-of-way into play for any work near the Haines Street and 217 exits. The OR-217 boundary on the northwest puts a second ODOT corridor into the mix. Inside those edges, City of Tigard right-of-way rules apply on the local-street grid -- SW 68th Parkway, SW Dartmouth Street, SW Hampton Street -- and the City has its own permit process for downtown-improvement-district scope.
The Triangle Strategic Plan layered a third constraint on top: new mixed-use development with sustainability requirements that include EV-charging infrastructure, stormwater treatment planters, and bicycle network tie-ins. Paving scope for a new Triangle mixed-use lot has to coordinate with those civil packages from the schematic-design phase forward.
The Three Triangle Project Types We Quote
Most Tigard Triangle paving demand sorts into three buckets. First, retail anchor and strip-center surface lots along the 99W frontage, where the scope runs 8,000 to 60,000 square feet of mill-and-overlay scheduled around retailer black-out windows and ODOT 99W lane-closure permits. Second, multi-tenant office and light-commercial lots along SW 68th Parkway and SW Dartmouth, where the buyer is a property manager and the scope is mid-life mill-and-overlay or full-depth replacement on lots from the 1980s-90s build-out. Third, new mixed-use surface lots and parking-deck approaches built under Triangle Strategic Plan rules, which carry EV-charger pad spec, stormwater swale tie-ins, and Plan-mandated bicycle facility coordination.

Industry Cost Picture for Tigard Triangle Paving
Triangle paving sits in the upper band of Washington County commercial pricing because of the ODOT-coordinated work-zone overhead, the night-pour requirements on 99W frontage, and the Triangle Strategic Plan compliance scope. A phone quote will not hold up.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total |
|---|---|---|
| Retail anchor mill-and-overlay | $4 to $8 | $40,000 to $300,000+ |
| Multi-tenant office, phased | $4 to $7 | $30,000 to $400,000+ |
| Mixed-use new lot (Strategic Plan) | $6 to $11 | $80,000 to $800,000+ |
| Full-depth replacement | $9 to $16 | $35,000 to $300,000+ |
| Driveway approach on 99W frontage | $7 to $13 | $8,000 to $30,000+ |
Current Market Reality
Tigard Triangle projects routinely run above the published baseline for three reasons. First, ODOT 99W traffic-control plans require certified flagger crews, written lane-closure schedules, and 4-to-8-week permit windows -- the contractor recovers that overhead in the bid. Second, retail anchor work on the 99W frontage forces night pours from roughly 9 PM through 6 AM, with retailer black-out windows compressing the schedule on either side and adding 20 to 40 percent in overtime labor. Third, Triangle Strategic Plan compliance on new mixed-use scope includes EV-charging pad spec, stormwater swale planters, and bicycle facility integration that line-item separately from the asphalt scope. Cojo will not phone-quote a Triangle lot -- the site walk and the written scope are how this district gets priced.
For the striping follow-up scope that almost always bundles with Triangle paving, the Tigard Triangle striping guide covers ADA stall ratios, EV-charger striping retrofits, and thermoplastic versus paint decisions for 99W-frontage retail lots.
Permits, Night Work, and Strategic Plan Compliance
The permit stack for a Triangle paving job depends on which boundary the work touches. 99W frontage work needs an ODOT right-of-way permit with a certified traffic-control plan. I-5 and OR-217 boundary work needs the same. Interior local-street work needs a City of Tigard right-of-way permit for any tie-ins to SW 68th Parkway, SW Dartmouth, or SW Hampton. New mixed-use scope triggers Triangle Strategic Plan review for stormwater, EV-charger placement, and bicycle facility integration. Night-pour permits restrict work to overnight windows on 99W and impose 24-hour notification requirements for adjacent retail tenants.
How to Vet a Tigard Triangle Bidder
Three questions filter the bidder field. First, ask whether the bid includes the ODOT 99W traffic-control plan submission and permit fee, or whether those are extras -- a bidder who lists "permits by owner" is shifting risk you should not accept. Second, ask for a specific Triangle reference -- a job between SW 68th and SW Hall in the last 18 months, with the property named. Third, ask about Triangle Strategic Plan compliance experience if the scope is new mixed-use construction; if the contractor has not run a Plan-reviewed project, the schedule will slip.
A fourth filter that separates the right contractor from the wrong one on Triangle work: ask for the proposed mix design and lift schedule. A retail-anchor lot on 99W frontage typically calls for a 2-inch wear-course lift over a 3-inch binder lift on full-depth replacement, with a PG 64-22 binder grade selected for the wheel-load concentration at the drive aisles. A bidder who answers in generic "we use a standard commercial mix" terms is not engineering the work to the Triangle's traffic profile. The right answer names the binder grade, the lift thicknesses, and the aggregate gradation, and connects each spec to the load and ODOT-corridor exposure at the parcel.
Once the new lift is down, asphalt maintenance on a 24- to 36-month rotation is what protects the capital against the 99W-frontage wear pattern.
