Hunter Mill Road bends where it does because of a tree. A white oak roughly 100 feet tall and six feet across at the base stands just north of Route 123, and the road was curved around it rather than through it. Worth knowing before you call anyone about tree service in Oakton: the first question is rarely what is wrong with the tree, but who has authority over it.

1Settle the authority. Your own land, VDOT right-of-way along Route 123 or Route 674, or an RPA buffer: you hear which one applies before anything is booked.
2Read the tree in person. An arborist checks root plate, union and crown on site, and that estimate is free.
3Keep it if pruning will do. Lifting a crown off the roofline or clearing deadwood often settles a big oak by the house without felling it.
4Remove and replant in one quote. If it has to come down, the drop zone is planned on the lot, the stump is ground, and replacement planting is priced alongside.
Virginia Tech’s Remarkable Trees project lists it as a historic landmark and records that the road was curved to save it. It is a sister to the tree the locality was named for, a massive oak that once stood at Chain Bridge and Hunter Mill roads.
In July 2019 a lightning strike dropped a major limb into the road. By April 2020 VDOT planned to remove the tree. Residents pushed back and VDOT stopped: “We are not going to remove the tree at this time,” the agency’s Allison Richter said. The tree is still there.
That is not trivia. A tree can be a landmark and still sit under someone else’s removal authority, because of where its trunk happens to stand.
On your own land, Fairfax County is direct: in general no law prohibits you from removing individual trees on your own property. No county permit to take down one or two trees in your yard.
In the road right-of-way, it is VDOT’s call, as the Hunter Mill oak showed. Chain Bridge Road is Route 123, Hunter Mill Road is Route 674. A trunk in the right-of-way is a state matter, not yours and not the county’s.
Inside a Resource Protection Area, the answer changes again. Under Chapter 118, the Chesapeake Bay Preservation Ordinance, land within 100 feet of a perennial-flow waterway, wetland or major floodplain is an RPA. Clear-cutting is prohibited, as is removing native vegetation to create lawn. Removal is allowed with county approval for dead or diseased trees and invasives (with replacement planting), and for sight lines, access paths and erosion control. Check your parcel on the county’s Watershed and Resource Protection Area Viewer first.
Land disturbance over 2,500 square feet needs a county permit; the Engineer of the Day is 703-324-2268. For forest and pest questions, Urban and Community Forestry is 703-324-1770.
Difficult Run drains 57.7 square miles straight to the Potomac, the county’s largest watershed. Tributaries include Piney Branch, Colvin Run, Rocky Run and Wolftrap Creek. The Comprehensive Plan says of Oakton’s Fox Lake sector, north and west, that it is almost entirely within the Difficult Run Watershed.
You can walk it. The Gerry Connolly Cross County Trail begins at Oakmont (formerly Oak Marr) Park and follows the stream valley north past Miller Heights, Vale and Hunters Valley roads for about six miles. The eastern edge toward Vienna drains the other way, toward Accotink Creek.
Where the divide runs is not something to guess at. If your lot backs onto a stream, the Viewer answers it and a site visit confirms it.
The county’s master plan for Oakton Community Park (9.81 acres at 2841 Hunter Mill Road) calls it immature hardwood heavily impacted by invasive species and deer browse, roughly two-thirds forest. The survey records white oak, red maple, tulip tree, black cherry, black walnut and catalpa, plus autumn olive and Japanese honeysuckle.
Those invasives do not stop at the park boundary, and deer browse strips the understory that would otherwise replace the canopy. On a wooded lot here the next generation of trees is not coming up on its own.
The county documents oak decline in red, white, chestnut and black oak: dieback from the top of the canopy down, epicormic sprouting, a crown thinning each season. The causes combine, age, drought, compacted soils, restricted root space, heat, construction damage, spongy moth, and the county states plainly there is no cure, cautioning against treatments that promise to reverse it.
Bacterial leaf scorch looks similar and is not the same thing. Virginia Cooperative Extension describes it as often lethal, spread by sharpshooter leafhoppers and spittlebugs, blocking water movement in the xylem, most common on oaks of the red oak group, elm and sycamore. The tell is a scorched leaf margin with a yellow band between brown and green, late summer into fall, worse in drought. No cure; injection only slows it. A proper tree health assessment is what decides whether you are managing a tree or planning its replacement.
On March 16, 2026 a tornado watch became a flood warning countywide, with Oakton named among locations seeing flooding. Trees came down at Fox Mill and Lawyers roads and at Towlston and Leigh Mill. On September 3–4, 2026 gusts hit 69 mph at Tysons, leaving about 16,464 county customers without power. Wet ground and wind is what takes a large oak over at the root plate rather than the union, and storm damage cleanup calls cluster after exactly that. Report downed lines to Dominion at 1-866-366-4357 or NOVEC at 703-335-0500, roads to VDOT at 1-800-367-7623, and call 911 for anything life-threatening.
On these lots the job is rarely one clean tree removal. A large oak near the house gets read first: our certified arborists check the root plate, the union and the crown before a tree service quote is written, and often the answer is structural pruning, not removal. Lifting a crown off a roofline, taking deadwood out of a tulip tree, stump grinding once the tree is down, storm cleanup when a limb comes through a fence. Where a tree must go, safety planning happens on site: the drop zone on a wooded acre is decided by what else is standing.
The landscape around the stump matters too. With deer browse and invasives suppressing regeneration, removing a canopy tree without a replanting plan usually means autumn olive fills the gap. Our team quotes the removal and the replacement together, so tree care for the trees left standing is part of the same conversation, more or less how every property here gets scoped.
An oak leaning toward the house on a wooded acre off Vale Road or Hunter Mill? One visit tells you whether it stays, gets pruned or comes down.
This is an unincorporated census-designated place, not a town and not a city, covering 9.76 square miles, population 36,732 at the 2020 census, ZIP 22124, in the Providence District. It borders Vienna to the east and Fairfax to the south, with Fair Oaks to the west and Wolf Trap to the north. Crews here also cover neighboring tree service in Vienna and tree service in Fairfax work, along with tree service in Merrifield, another Providence District community.
We work the subdivisions around the community park, Oakcrest Farms, Lewis Manor, English Oaks and Hunterbrooke, along with Oakton Village, Oakton Gable, Five Oaks Estates, Four Winds at Oakton, Valewood Manor, Oakborough Square and Grays Oakton, plus properties on Vale Road, Blake Lane and Jermantown Road.
Whether it is a white oak by the drive or a crown thinning at the back of a wooded lot, the first visit settles who has authority over the tree and what it actually needs.

Do I need a permit to remove a tree on my Oakton property?
Generally not. The county states that in general no state law prohibits removing individual trees on your own property. The exceptions are a Resource Protection Area, a conservation easement, or land disturbance over 2,500 square feet.
The tree is right at the road. Who decides?
If the trunk stands in the right-of-way, VDOT does; the Hunter Mill Road oak is the example. If it is on your side of the line, it is yours. Worth confirming before tree removal is scheduled, not after.
How do I know if my lot is in an RPA?
Check the county’s Watershed and Resource Protection Area Viewer. Most of northern and western Oakton drains to Difficult Run. Inside an RPA even a dead tree needs county approval, usually with replacement planting.
My neighbour’s tree is leaning over my fence.
The county has no authority over neighbour disputes on private property and recommends contacting a licensed arborist. A written assessment from our arborists is what moves those conversations.
My oak is thinning from the top. Is it oak decline?
Possibly, and possibly bacterial leaf scorch. The scorch tell is a yellow band between brown and green on the leaf margin. Neither has a cure, but tree health management differs, so the diagnosis matters.
Why does nothing regrow under my trees?
Deer browse and invasives. The county survey at the community park found immature hardwood heavily impacted by both. Replanting there needs protection to survive.

G&V just left our house and because the experience was so good, I was compelled to write a review right away. I am absolutely satisfied with their work! The front of our home was a mess with a ton of weeds and overgrown plants. As a result, I searched Yelp and found G&V Tree and Landscaping Services. I was especially impressed with the great reviews. From the 1st call for the estimate through today, every communication was professional and helpful. We ended up getting the front redone. By the time I got home I was amazed with how everything looked. I thought I was at a different house! Furthermore, the two gentleman who did the work which included a tree trim, weeding, and redone front, really could not have been nicer. I could really tell they took a lot of pride in their work. I cannot recommend G & V enough!

A note to Mario and his staff for his professionalism and timeliness with tree service at our outdoor storage facility. We have a number of trees along the back fence line that consequently require maintenance and can be tricky to access. We have used G&V for several tree removal and trimming projects in this area so far. They respond to our requests quickly and most of all complete the work on time and with clean-up included. In addition, they also have online bill pay, which is nice. Highly recommend!

I contacted G&V on the morning because of an impending storm. I need them for emergency removal of a dead tree that as a result, would have caused severe damage to my home. Mario and his crew not only arrived within the hour, they worked into the beginnings of the storm itself to assure my home was safe. Therefore G&V has my highest recommendation for exceptional customer service, fair pricing, and quality of work. A 5-star rating is not high enough for G&V.

I cannot say enough positive things about G&V Tree and Landscaping Services. They got back to me right away and scheduled to come out within a day to give a quote. The quote was beyond reasonable for the work and they were able to come out and do it in just four days. Their team arrived on time and was so courteous and thorough. They trimmed four trees in my backyard that were very overgrown and cleaned everything up afterwards. I will definitely be using them again and recommend them to friends.
