Rivergrove, Lake Grove, and the Small Communities Around Lake Oswego That Nobody Outside the South Metro Can Name — And Why We Deliver to All of Them

If you do not live in the south metro, you probably think Lake Oswego is one place. It is not. It is a patchwork of neighborhoods, unincorporated communities, and — in at least one case — an entirely separate city that most Portland residents do not know exists.

We deliver flowers to all of them. Every day. And after years of navigating these streets, we can tell you: they are not interchangeable. Each community has its own character, its own housing stock, its own residents, and its own relationship with the name “Lake Oswego.” Some embrace it. Some tolerate it. And one tiny city stubbornly insists it is something else entirely.

Here is the map. We already wrote about Lake Oswego proper. This is everything around it.

🏛️ Rivergrove: The City That Refused to Disappear

Population: Approximately 500 people.
Status: Incorporated city with its own city council, mayor, and fierce independence.
Location: Wedged between Tualatin and Lake Oswego along the Tualatin River, roughly between Childs Road and Pilkington Road.

Rivergrove is the smallest incorporated city in the Portland metro — smaller than Durham, which at least has 2,000 people. Rivergrove has about 500. It has its own city council. It has its own planning commission. It does not have its own post office, police department, or commercial district. What it has is a community that chose to be its own thing and has maintained that choice for decades.

The story is similar to Durham’s: Rivergrove incorporated in 1971 specifically to resist annexation by Lake Oswego. The residents wanted to keep their properties rural and low-density. They did not want Lake Oswego’s zoning rules, Lake Oswego’s tax rates, or Lake Oswego’s development pressure. So they became their own city.

Fifty-plus years later, Rivergrove remains almost entirely residential. The lots are large. The trees are mature. The streets are quiet. And the residents are fiercely protective of the identity they built — even though GPS usually says they live in “Lake Oswego” or “Tualatin.”

Delivery notes: Rivergrove addresses typically show up as Lake Oswego or Tualatin in mapping databases. Our drivers know the area by street, not by city name. If you are ordering flowers for someone in Rivergrove, just enter the street address — we will find it.

🌲 Lake Grove: The Neighborhood That Was Here First

What it is: An unincorporated community in the western part of the Lake Oswego area, centered along Boones Ferry Road south of Kruse Way.
Character: The part of Lake Oswego that does not feel like Lake Oswego.

Lake Grove predates Lake Oswego as a community name. It was a rural settlement before Lake Oswego was a city, and it retains some of that original, less-polished character. The housing stock is more varied than downtown Lake Oswego — you will find mid-century ranches, 1970s split-levels, newer construction, and the occasional oddball property that looks like it belongs on a country road rather than a suburban street.

The Boones Ferry Road corridor through Lake Grove is the commercial spine — grocery stores, restaurants, coffee shops, small businesses. It is less manicured than downtown Lake Oswego and more practical. Residents of Lake Grove tend to identify with the neighborhood name rather than the city: “I live in Lake Grove” rather than “I live in Lake Oswego.” The distinction matters to them.

Why we know Lake Grove well: Boones Ferry Road is one of our primary delivery corridors between Tualatin and Lake Oswego. Our drivers run this road multiple times daily. Lake Grove addresses are some of the most common on our route sheets.

🏡 First Addition: The Walkable Historic Core

What it is: The original residential neighborhood of Lake Oswego, platted in the early 1900s, centered roughly between State Street, A Avenue, and the lake.
Character: Tree-lined streets, Craftsman bungalows, historic homes, and the closest thing Lake Oswego has to a walkable urban neighborhood.

First Addition is where downtown Lake Oswego meets residential life. You can walk from a Craftsman-era cottage to a restaurant on A Avenue in five minutes. The homes are smaller and older than the lakefront estates, but they have something the estates do not: walkability, character, and neighborhood density that creates genuine community.

First Addition residents tend to be deeply attached to their neighborhood. They chose it specifically — for the trees, the architecture, the proximity to downtown, and the feeling of living in a place with history rather than a development.

Delivery notes: First Addition streets are narrow, tree-canopied, and occasionally tricky for the delivery van. Parking can be tight. Our drivers know to use the side streets and to look for house numbers that are sometimes hidden behind mature landscaping. If your recipient’s house number is hard to see from the street, mention it in the delivery notes.

🏔️ Mountain Park: The Planned Community on the Hill

What it is: A large planned community on the south side of Lake Oswego, built in the 1970s and 80s, with its own recreation center, pools, tennis courts, and trail system.
Character: Suburban, well-maintained, family-oriented, and self-contained.

Mountain Park is a community within a community. It has its own homeowners association, its own recreation facilities, and a trail network that connects the neighborhoods without requiring a car. The housing ranges from townhomes and condos to single-family homes on wooded lots.

Mountain Park residents often identify with the community name first: “I live in Mountain Park” is more common than “I live in Lake Oswego.” The recreation center is the social hub — swim meets, tennis leagues, community events, and the kind of neighborhood life that planned communities aspire to but rarely achieve.

Delivery notes: Mountain Park has a gateless entry but the internal streets can be confusing for first-time visitors. Our drivers have learned the layout through repetition. Condos and townhomes need unit numbers in the delivery notes. For the recreation center, specify which entrance or building.

🌊 Westlake: The Newer Development

What it is: A residential area in the southwestern part of Lake Oswego, generally newer construction than the historic core, with a mix of larger homes and some commercial along Boones Ferry Road.
Character: Newer, more spacious, family-oriented, and closer to Tualatin than to downtown Lake Oswego.

Westlake is the part of Lake Oswego that borders Tualatin most directly. The homes are generally larger and newer than First Addition or Lake Grove. Families with children are drawn to the schools, the space, and the relative quiet. It feels suburban in a comfortable, unhurried way.

Residents of Westlake are often newer to the area — families who priced out of closer-in Portland or who moved from out of state and chose the south metro for schools and quality of life. They shop in both Lake Oswego and Tualatin. Their kids play sports in both communities. The boundary between Westlake and Tualatin is more of a gradient than a line.

Delivery notes: Westlake addresses are straightforward. Wide streets, visible house numbers, easy access. Some of the simplest deliveries on our Lake Oswego route.

🏛️ Marylhurst: The Campus That Was

What it is: A small area along Highway 43 south of Lake Oswego, historically defined by Marylhurst University, which closed in 2018.
Character: Transitional. The university campus is being redeveloped, and the neighborhood identity is evolving.

Marylhurst University operated on a beautiful wooded campus overlooking the Willamette River from 1893 until its closure in 2018. The campus was a landmark — the chapel, the art building, the old-growth trees. For decades, “Marylhurst” meant the university.

Now the campus is being redeveloped, and the Marylhurst name is gradually shifting from “where the university was” to “the neighborhood between Lake Oswego and West Linn.” The surrounding residential area remains quiet and wooded, with views of the Willamette and access to trails. It is one of the most scenic pockets in the south metro.

Delivery notes: Marylhurst addresses along Highway 43 and the surrounding residential streets are on our Lake Oswego/West Linn delivery corridor. The area is hilly and wooded. Some driveways are long and steep. Our drivers appreciate a note about driveway conditions or alternative drop-off points if the property is on a steep grade.

📍 The Address Confusion

Here is the practical reality of delivering flowers in this area: the addresses do not always match the community names.

  • Rivergrove addresses usually say “Lake Oswego” or “Tualatin” in the USPS database
  • Lake Grove addresses say “Lake Oswego” even though Lake Grove residents may not identify with that name
  • Mountain Park addresses say “Lake Oswego”
  • Marylhurst addresses say either “Lake Oswego” or “Marylhurst” depending on the database
  • Westlake addresses say “Lake Oswego” but could just as easily be filed under “Tualatin” by a confused GPS

None of this matters to us. We route by address and street knowledge, not by city name. Enter the street address and we will get the flowers to the right door — whether the database says Lake Oswego, Tualatin, Rivergrove, or something else entirely.

💐 What These Communities Order

The micro-communities around Lake Oswego have distinct ordering patterns:

  • Rivergrove: Similar to Durham — longtime residents, sympathy orders, neighbor-to-neighbor gestures, milestone birthdays. The orders are personal and specific.
  • Lake Grove: Practical and frequent. Birthday deliveries, thank-you flowers, office-adjacent orders from the Boones Ferry corridor businesses.
  • First Addition: High-design requests. Customers who know what they want, reference specific flowers, and care about the vase as much as the arrangement. The aesthetic bar is high.
  • Mountain Park: Community-driven. Group gifts for neighbors, team celebration flowers, swim-meet congratulations, and the steady drumbeat of family occasions in a neighborhood with a lot of families.
  • Westlake: Young family orders. New-baby congratulations, housewarming flowers, “we just moved here and want to make friends” neighbor gifts.
  • Marylhurst: Lower volume but high-value. The homes in this area tend to be larger, the orders tend to be more premium, and the recipients tend to be pleasantly surprised by how scenic the delivery drive was.

🌿 One Delivery Area, Six Personalities

When people say “Lake Oswego,” they are describing a region, not a monolith. Rivergrove is not Lake Grove. First Addition is not Mountain Park. Westlake is not Marylhurst. Each community formed under different circumstances, attracted different residents, and developed a different personality.

We appreciate that. Our drivers see the differences every day — in the architecture, the landscaping, the neighborhoods, and the people who open the door. A delivery to a Craftsman cottage in First Addition feels different from a delivery to a townhome in Mountain Park, which feels different from a delivery to a rural property in Rivergrove. The flowers are always beautiful. The context changes.

Browse our arrangements, plants, and gifts. Same-day delivery to Rivergrove, Lake Grove, First Addition, Mountain Park, Westlake, Marylhurst, and all of Lake Oswego — plus Tualatin, Sherwood, Wilsonville, and across the south metro. Six communities, one delivery route, every door. 🏘️
