Cojo runs striping crews into the 97124 zip -- the Silicon Forest section of Hillsboro, home to Intel's Hawthorn Farm and Ronler Acres campuses, Genentech's Hillsboro site, and a dense ring of tech-tenant and contractor-support lots that fill the area between Cornell Road, NW Cornelius Pass, and the Sunset Highway. The work here is large-format commercial -- corporate campus visitor and employee lots, contractor staging yards, ADA and EV stall mapping at meaningful scale, and the prevailing-wage compliance that comes with public-money-adjacent work. Pricing depends on stall count, lot complexity, and scheduling constraints, but most local jobs land within the published baseline range below.
Striping Work in Silicon Forest -- The Local Picture
97124 is unlike any other Washington County zip. The dominant tenants -- Intel and Genentech anchor the area, plus dozens of supporting tech, biotech, and contractor businesses -- run large, multi-thousand-stall parking footprints with documented campus standards. Visitor lots, employee lots, shuttle lots, contractor staging, and badged-access perimeters all need consistent ground markings to the campus spec.
Surrounding commercial work fills out the rest of the zip. Cornell Road retail, Tanasbourne adjacency on the south edge, and the Sunset Highway corridor all run normal mid-size commercial striping. Apartment and townhome developments fill in the residential footprint.
Two regulatory layers matter more here than in other Hillsboro zips. ADA compliance at this scale is non-trivial -- a 1,000-stall lot needs 21 ADA stalls minimum under the federal 2010 ADA Standards, with the right mix of standard and van-accessible. EV charging stall requirements have been expanding under Oregon law and Hillsboro code, especially for new construction and major renovations. Both compliance areas get audited when tenants change or campus expansions trigger permit review.
Striping Scopes We Run in 97124
The most common 97124 jobs:
- Corporate campus re-stripe -- standardized ground markings across employee, visitor, and shuttle lots to a campus spec.
- Large retail re-stripe -- 300 to 1,000 stalls with ADA, EV, fire-lane, and arrow/text stencil work.
- Contractor staging yard layout -- temporary or semi-permanent ground markings for project staging, equipment storage, and material yards.
- EV charger stall buildout -- new EV stalls or re-mapping existing ones with the required ground stencils, green outline, and signage.
- Fire-lane re-mark -- Hillsboro Fire compliance, with red curbs and stencils.
- Thermoplastic upgrade for high-wear areas -- entries, drive-through queue lanes, and main aisles where waterborne paint wears too fast.
97124 jobs are larger than the Washington County norm. A typical Silicon Forest employee lot runs 500 to 2,500 stalls; a major retail center runs 300 to 800.
Striping Cost for 97124 Lots

Current Market Reality
The published ranges assume a clean, paved surface, daytime work, and waterborne traffic paint. Silicon Forest jobs that require night work to keep campuses open, prevailing-wage rates on public-money-adjacent contracts, badged-contractor logistics with security coordination, or thermoplastic for high-wear positions run above the baseline. Material costs have moved over the last several seasons. Quotes older than 30 to 60 days should be re-validated.
Prevailing Wage and Tech-Campus Coordination
Two things make Silicon Forest jobs different from a normal Washington County retail stripe:
Prevailing wage. When the work is on contract with a public agency, with a federally funded tenant, or under specific tenant agreements, Oregon BOLI prevailing-wage rates apply. That changes the labor math significantly. We have to verify whether prevailing wage applies before quoting, and the rate sheet is public record.
Campus coordination. Tech-campus customers typically have documented contractor procedures: badged access, escorted entry, restricted hours, environmental health and safety briefings before work starts, and specific waste-disposal protocols. None of that is paint or labor, but it's coordination time that gets folded into the bid.

ADA and EV Compliance at Scale
Two specific recurring gaps on 97124 audits:
ADA stall counts. A 1,000-stall lot legally needs at least 21 ADA stalls, and at least 4 must be van-accessible (8-foot access aisle). Many older Silicon Forest lots installed under earlier code don't hit modern counts. Re-stripe is the moment to bring the math current.
EV stall planning. Adding EV charging without coordinated striping creates problems. EV stalls need their own ground markings, signage, and conflict-free locations (not in ADA spots, not in fire lanes, not blocking primary drive aisles). Campus expansions often retrofit EV stalls into existing layouts; we map the conflict resolution during the walkthrough.

Picking a Striping Contractor for 97124
What to verify:
- Oregon CCB license -- required by law.
- Paint and material spec -- waterborne, oil-based, or thermoplastic, with rates.
- ADA and EV audit -- the quote should call out compliance review explicitly.
- Campus-procedure compliance -- badged-contractor experience, ability to work to a campus spec, environmental health and safety briefings on file.
- Night-work and prevailing-wage options -- if either applies, the quote should price them.
- Insurance -- general liability and workers' comp, often at campus-specified higher limits.
