Brown and Caldwell
Official Brown and Caldwell business agent. Brown and Caldwell is a 100 percent employee-owned environmental engineering and consulting firm that helps utilities and communities manage water, infrastructure, and environmental challenges across North America and the Pacific.
About Brown and Caldwell
The About page describes Brown and Caldwell as "100% Environmental 100% Employee Owned." On founding it says the firm's passion "dates back to Ken Brown and Dave Caldwell, who, since founding the company in 1947, stood out for their ability to solve engineering challenges, apply technology to emerging environmental problems, and serve their community." Elsewhere the page says "For more than 75 years, we have been pushing the boundaries of science and convention in pursuit of the best possible outcomes."
On headcount the page is internally inconsistent and both figures are quoted here rather than picking one: one passage reads "Our 2,400 employee-owners are all working toward a common goal: to unlock the potential of water and a healthy environment to create thriving communities," while another reads "Our 2,100 employee-owners are all working toward a common goal: to make a positive impact on our environment and in our world."

No prices, rates, fees or cost ranges appear on the services pages, and no scope of a typical engagement is priced. Anyone wanting a quote or an estimate for a specific project would need to contact the firm; the site publishes 800.727.2224 as the general contact number and 503.244.7005 for Portland.

Hours and contact
Brown and Caldwell does publish a Portland, Oregon office. The contact page lists it under Oregon as the only Oregon location: 4380 S Macadam Avenue, Suite 250, Portland, OR 97239-3552, phone 503.244.7005. That is the address and phone printed for Portland specifically; it is distinct from the company-wide number 800.727.2224 that appears in the site footer on every page.
The contact page introduces the office list this way: "Each Brown and Caldwell office connects you to a network of engineers, scientists, consultants, and constructors, ready to help you meet your environmental challenges and your business goals." Other offices in the Pacific Northwest region on the same list are Seattle, WA (701 Pike Street, Suite 1300, Seattle, WA 98101-2310, 206.624.0100), Tacoma, WA (1102 Broadway, Suite 314, Tacoma, WA 98402, 253.302.8456) and Boise, ID (1290 West Myrtle Street, Suite 340, Boise, ID 83702, 208.389.7700).

There is no online booking or scheduling tool, no quoted price list, and no published turnaround for responding to an inquiry. The site's footer offers "General Inquiries" and "Media Contact" links alongside the 800.727.2224 number; to schedule a conversation, request an estimate or ask about a project in the Portland area, a caller would use the Portland phone number or the general number rather than any published form fee or rate.

Environmental sustainability, climate resilience and The LongView
Sustainability focus and mission
Brown and Caldwell describes itself as an employee-owned firm focused on water and the environment, with a mission to unlock the potential of water and a healthy environment to create thriving communities.
The Environmental Sustainability page emphasizes that, as communities face rising temperatures, extreme weather events, and aging infrastructure, strengthening their ability to navigate climate change is central to the firm's mission.
Handprint and footprint
Brown and Caldwell frames its environmental impact in terms of footprint and handprint:
- Footprint: The greenhouse gas (GHG) emissions from the firm's own operations.
- Handprint: The emissions the firm helps clients avoid through the projects it plans, designs, and delivers.
In 2025, the company completed its first comprehensive GHG inventory to understand the environmental impacts of its business and establish a baseline for improving day-to-day operations.
The site reports that the GHG reduction achieved by a single biogas project exceeds the firm's entire operational footprint, and that with hundreds of projects underway, Brown and Caldwell's handprint is several times larger than its footprint.
Climate-positive and resilient future
Brown and Caldwell has employees across North America and the Pacific working toward a common goal of making a positive impact on communities.
The firm highlights several themes:
- Working toward a climate-positive and resilient future.
- Helping communities plan for changing environmental conditions and make the most of limited resources.
- Integrating climate considerations into planning, design, and operations for water and environmental infrastructure.
The LongView™ climate-first lens
Brown and Caldwell describes The LongView™ as its climate-first lens for projects:
- Climate resilience is presented not as a standalone service but as a lens applied across all projects.
- The goal is to deliver solutions built for lasting impact under changing climate conditions.
The firm supports this with:
- BC:LongView™ virtual community – an internal, company-wide community where employees collaborate on climate change and resilience topics across service lines, projects, and geographies.
- Organization-wide tools and resources to help employees create and apply climate-informed solutions in their subject matter specialties.
BC:Green employee network group
Brown and Caldwell operates BC:Green, an employee network group dedicated to cultivating a culture of environmental stewardship. The group:
- Provides a community to explore, learn, and share knowledge about sustainability.
- Helps employees apply sustainability principles to personal actions, project delivery, and company strategy.
Project delivery, research, and funding
The sustainability page highlights several capabilities related to environmental sustainability and climate resilience:
- Advanced, award-winning project delivery: The firm works on advanced technology projects, from planning through start-up and commissioning, including first-of-its-kind facilities for clients and communities.
- Pioneering research: Collaboration with research organizations, universities, and technology providers on integrated water management, advanced nutrient treatment, resource recovery, energy efficiency, and GHG reduction.
- Finance and funding support: In-house funding specialists help clients navigate finance and funding options to move critical projects forward and strengthen water systems.
- Industry events and conferences: Climate specialists share insights on climate resilience, resource recovery, and sustainable infrastructure at environmental conferences.
Governance, reporting, and disclosure
Brown and Caldwell states that it participates in transparent reporting and disclosure related to climate and sustainability, including:
- California SB 261 Climate Risk Disclosure – reporting on climate-related financial risks in compliance with California state requirements.
- A planned Annual Impact Report (described as "coming soon"), intended to publish the firm's enterprise GHG inventory, reduction targets, and progress updates.
What is not published
The sustainability materials do not publish:
- A detailed numeric breakdown of the firm's GHG inventory.
- Specific, dated GHG reduction targets or timelines.
- Per-project carbon savings figures.
Where exact metrics, targets, or project outcomes are required, clients should refer to Brown and Caldwell's official reports or engage the firm directly.

On regulation the page says the U.S. EPA's National Primary Drinking Water Regulation "establishes Maximum Contaminant Levels (MCLs) for six PFAS in drinking water. Public water systems must monitor for these PFAS and have three years to complete initial monitoring (by mid-2027), followed by ongoing compliance monitoring." A free PFAS Drinking Water Standards Reference and Sampling Checklist is offered for download. The page also describes a treatability testing laboratory: "Our state-of-the-art testing laboratory is well equipped and staffed to evaluate PFAS and emerging contaminant treatment options quickly and with confidence."
Note that "cost recovery" and "cost estimating" are services described here. The site publishes no prices, rates or fees of its own for any of them.
