If you’re staring at a map of Washington State, specifically that sun-drenched, desert-like corner where the Yakima, Snake, and Columbia Rivers all collide, you’re looking at Richland. But if you need to know what county is Richland WA, the answer is Benton County.
It's a simple answer. Benton County.
Yet, for anyone actually living here or planning a move, the "where" is way more complicated than just a line on a government map. Richland is one-third of the Tri-Cities, a weird and wonderful metropolitan sprawl that also includes Kennewick and Pasco. While Richland and Kennewick share Benton County, Pasco sits across the river in Franklin County. Honestly, people get confused all the time because the three cities function like one giant, spread-out organism.
Why Benton County Matters More Than You Think
Richland isn't just another suburb. It’s the intellectual hub of the region. Because it sits in Benton County, it houses the Pacific Northwest National Laboratory (PNNL) and is the gateway to the Hanford Site. This gives the "Richland" part of Benton County a very specific vibe. You've got a massive population of scientists, engineers, and researchers living in a place that, decades ago, was basically just a tiny farming village.
Government-wise, being in Benton County means your records, property taxes, and court systems are tied to Prosser, which is the county seat. It’s a bit of a drive from Richland, which feels funny since Richland is way more populous than Prosser. But that’s rural Washington for you.
The county lines define everything from school district funding to how the local police departments coordinate. In Richland, you’re dealing with the Benton County Sheriff’s Office if you wander into the unincorporated areas, but the Richland Police Department handles the city proper.
The Nuclear Legacy of Benton County
You can't talk about Richland without talking about the Manhattan Project. This isn't just history; it's the literal foundation of the city. Back in the 1940s, the government basically seized this chunk of Benton County to create a "secret city" for workers at the Hanford Site.
They built what are known as "Alphabet Houses." If you walk through central Richland today, you’ll see them. Houses designated by letters—A, B, F, H, and so on—based on the floor plan and the worker’s rank. Living in an "A House" in Benton County is a badge of honor for locals. It means you’re living in a piece of atomic history.

The Geography is... Dry
If you’re coming from Seattle, prepare for a shock. Benton County isn't the "Evergreen State" you see on postcards. It’s the shrub-steppe. It’s brown. It’s windy.
Richland sits in a rain shadow. We get maybe seven or eight inches of rain a year. Most people think Washington is all moss and raincoats, but in this part of Benton County, it’s all about sagebrush, basalt cliffs, and irrigation. Without the Columbia River, Richland wouldn't exist. The river is the lifeblood. It provides the water for the massive vineyards that have turned Benton County into a global wine powerhouse.
Beyond the Basics: The Tri-Cities Dynamic
So, we established that what county is Richland WA is Benton. But you really have to understand the neighbors.
- Kennewick is the "retail" sibling. It’s got the mall, the big box stores, and the massive Toyota Center. It’s also in Benton County.
- Pasco is the "agricultural and transport" sibling. It’s in Franklin County.
When you live in Richland, you’re constantly crossing county lines. You might live in Benton County, work at the Hanford Site (Benton), but go to a minor league baseball game at Gesa Stadium in Pasco (Franklin). It's a weird, seamless transition. The only way you really know you’ve switched counties is the color of the police cars and the name on your tax bill.
Getting Around Richland
Traffic in Richland isn't "Seattle bad," but the George Washington Way—the main artery—can be a nightmare during the Hanford shift change. People call it "G-Way." If you’re moving here, learn that name.
Public transit exists via Ben Franklin Transit. It covers both counties (Benton and Franklin, hence the name). It’s actually a pretty decent system considering how spread out the desert is. But honestly? You need a car. You absolutely need a car to survive in Benton County.
The Economy of Richland and Benton County
Benton County is surprisingly wealthy compared to other rural parts of the state. This is largely due to the high-paying jobs at PNNL, Hanford, and Kadlec Regional Medical Center.

The "Hanford Cleanup" is the largest environmental remediation project in the world. It pumps billions of dollars into the local economy every year. While some people worry about the "nuclear" aspect, locals mostly see it as a stable source of high-paying jobs. It has created a community that values education and science. Richland High School’s mascot is the "Bombers," and their logo is a mushroom cloud.
For an outsider, that’s shocking. For someone in Benton County, it’s just heritage.
Agriculture and the Red Mountain AVA
While the north end of the county is all about science, the south and west are all about grapes. The Red Mountain American Viticultural Area (AVA) is right on Richland’s doorstep. It’s one of the most prestigious wine-growing regions in the world.
The heat in Benton County is intense. We get days over 100 degrees regularly in the summer. That heat, combined with the volcanic soil and the irrigation from the Yakima River, produces Cabernet Sauvignon that rivals Napa Valley. If you’re in Richland, you’re basically twenty minutes away from world-class wine tasting.
Realities of Living in Richland
Is it all sunshine and wine? Kinda. But there are downsides.
The wind is relentless. The "Kittitas Winds" or just the general Columbia Basin gusts can hit 50 or 60 miles per hour without much warning. Dust storms are a real thing here. If you have allergies, Benton County might be your nemesis. The sagebrush and the cheatgrass are everywhere.
Also, the cost of living has spiked. It used to be the "affordable" part of Washington, but the secret is out. Remote workers and retirees from the West Side (Seattle/Tacoma) are moving into Richland in droves. They want the 300 days of sunshine. This has pushed home prices in Benton County to levels that are making it hard for young families to stay.

Schools and Safety
Richland is generally considered the "safest" and most "family-oriented" of the Tri-Cities. The Richland School District is highly rated, largely because the tax base is so strong. You have a lot of PhDs as parents who are very involved in the schools.
The parks system is also incredible. Howard Amon Park, which runs along the Columbia River, is the crown jewel of the city. You can walk, bike, or kayak for miles. In the summer, the river is packed.
Making the Move: Practical Steps
If you’ve decided that Benton County is for you, there are a few things you need to do immediately.
Check your zip codes. Richland primarily uses 99352 and 99354. The 99352 area is the more established, "alphabet house" and riverfront area, while 99354 goes further north toward the labs.
Register your car. Since you’re in Benton County, you’ll go to the Auditor’s office for tabs and registration. Washington doesn't have a state income tax, which is great, but our sales tax is relatively high. In Richland, it’s around 8.7%.
Understand the water. In many parts of Richland, you have two water systems. You have "potable" water for your house (drinking, showers) and "irrigation" water for your lawn. The irrigation water is pumped straight from the river and is much cheaper. It’s also usually turned off in October and back on in April. If you don't blow out your sprinkler lines before the first big freeze in Benton County, you’re going to have a very expensive spring.
Actionable Advice for New Residents
- Visit the REACH Museum: If you want to understand the geology and the nuclear history of the area, go here first. It explains why the landscape looks the way it does.
- Get a Discover Pass: You’re close to places like Badger Mountain. The hiking is great, but you’ll want the pass for state parks.
- Find a "Badger Mountain" Routine: Hiking Badger is the unofficial sport of Richland. It’s a steep climb, but it gives you a 360-degree view of the entire county. You can see all the way to Mount Adams and Mount Rainier on a clear day.
- Prepare for the "Inversion": In the winter, the cold air gets trapped in the basin. It can stay grey and foggy for weeks while the mountains are sunny. It’s a psychological hurdle you have to be ready for.
Richland is a place of contrasts. It’s a nuclear town in a desert, a scientific hub in a farming county, and a quiet suburb with global importance. Knowing that Richland is in Benton County is just the starting point. The real experience is found in the river breeze, the smell of sagebrush after a rare rain, and the weird pride of living in a city that helped change the course of human history.
