What D&H Flagging does
D&H Flagging, Inc. is a privately held traffic control services company headquartered at 1621 SE Pardee St, Portland, Oregon, founded in 1989 and operating for over 35 years. The company provides certified flagging labor, traffic control equipment rental, and custom traffic control plan (TCP) creation to contractors, municipal and state government agencies, and residential/community event organizers across Oregon and SW Washington, with flagger crews also certified in Washington, Idaho, and Montana.
The core product set is organized around three service lines: on-site Traffic Control Services staffed by certified flaggers equipped with stop/slow paddles, hard hats, and reflective vests; Rental Equipment covering cones, barricades, channelizers, plastic drums, signs, arrow boards, PCMS message boards, truck-mounted attenuators, and light plants, with optional delivery, setup, and takedown; and Traffic Control Plans (TCPs), which are detailed regulatory drawings created in-house for submission to city, county, and state permit reviewers. D&H reports having produced over 8,500 TCPs with typical 2–3 business day turnaround and a 100% approval guarantee, and holds a specific exemption from the Portland Bureau of Transportation (PBOT) allowing site-specific TCPs to be drawn without the PBOT Basemap. Additional offerings include Summer Block Party Packages at $50 per weekend and free Flagger Certification classes for new hires, clients, and government agencies.
The business model is service-based and sales-led, with all work scheduled by phone through a centralized Dispatch team (48-hour minimum, 24-hour emergency dispatch available), TCP intake routed to a Planning team, and equipment quotes handled by an Estimating team. Revenue is generated through hourly flagging labor (with premium shift rates above $40/hr), equipment rental fees including delivery/setup, per-project TCP fees with rush surcharges, and flat-rate block-party packages. Distribution is entirely direct-to-customer with no digital self-serve channel, no mobile app, and no public API; marketing is limited to the company website and reputation-driven referrals in the regional Pacific Northwest market.
