What is a viewshed?
A viewshed is the land and water that can be seen from a particular viewing point, such as a Parkway overlook or a roadside pullout. It is a planning and design word rather than a legal term, and no Virginia statute defines it. A county plan policy to protect viewsheds is not, by itself, a rule that limits what happens on a private parcel.
Built like watershed: everything seen from one spot, instead of everything that drains to it
Viewshed is put together the way watershed is. A watershed is the land that drains to one point; a viewshed is the land and water that can be seen from one point. It is a planning and design word, and neither the Code of Virginia nor the National Park Service's scenery guidance gives it a formal definition, so a page quoting a legal definition of viewshed is quoting something else.
Every viewshed has two halves: a place where someone stands, and what that person sees. The National Park Service describes the first as viewing locations, which include viewpoints, roadside pullouts and other well known areas, and the second as features, which can be a single focal point like a historic home or a larger area like a river valley.
The edge of a viewshed is set by the land. In mountain country it is often a ridge line, the crest that hides whatever lies beyond it. Move the viewing point a few hundred feet along a slope and the edge moves with it, which is why two neighboring parcels can look out on very different pieces of the same valley.
The leaves move it too. A hardwood screen that hides a valley in July can open it once the leaves are down, so the same porch has a summer viewshed and a winter one, and when a property is shown changes which one a buyer sees; that timing question is taken up in does leaf season help showings.
The Parkway was laid out around its viewsheds, and the Park Service looks past its own boundary
Along the Blue Ridge Parkway the word is not abstract. The 2024 National Historic Landmark nomination for the Parkway says its designers had room to locate the road for the views.
they had substantial leeway in locating the roadway to take maximum advantage of dramatic viewsheds

The same nomination observes that distant, isolated patches of incompatible development visible in long range views from the Parkway tend to be minimized within the viewshed. It also records that where private land borders the road, residential and commercial development, signage, towers and transmission lines are readily apparent in places. Both are descriptions of what a traveler sees. Neither is a rule.
Whether views are completely inside the park or extend to areas outside park boundaries, the NPS is responsible for preserving important natural, cultural, and historic views into the future.
National Park Service, Understanding Scenery
That sentence states a responsibility. The federal rules against disturbing plants apply on National Park Service land, and whether anything limits a particular private parcel near the Parkway is a question for its recorded deed, a title search and an attorney. One historic tool for protecting the view from the road was the scenic easement on adjoining private land. What those instruments are is covered in what a scenic easement is, and building beside the road in can I build near the Blue Ridge Parkway.
A county plan that protects viewsheds, on land with no zoning to carry it out
Carroll County's 2024 comprehensive plan uses the word twice, and both uses show the distance between a policy and a rule.
Policy 10.5: Protect open space, viewsheds and environmental features that contribute to the visual beauty and natural aesthetic of Carroll County.
Carroll County 2024 Comprehensive Plan
The plan also lists protecting viewsheds among the purposes an overlay district can serve as part of a zoning ordinance. Carroll County has no zoning ordinance, so there is no overlay district to do that work. Land in the county is unzoned, and the viewshed policy states what the county wants, not a limit on any parcel. How the county regulates land without zoning is covered in does Carroll County have zoning.
A locality can adopt something enforceable that bears on views without naming them. Va. Code 15.2-2295.1 lets a locality with protected mountain ridges regulate the height and location of tall buildings or structures on those ridges by ordinance. That is a height rule on qualifying ridges, not a viewshed rule, and whether a county has adopted one is the county's to confirm; the details are in can I build on a ridge top.
A parcel whose long view faces the Parkway?
Send the location and what the view takes in. Lowell will name the records to check before that view goes into a listing. No cost, no obligation.
Got it. Thank you.

Questions this raises
Is a viewshed something that gets recorded with a deed?
No. A viewshed is an area seen from a point, not a legal instrument. What gets recorded is an interest in land, such as a scenic easement or, under Virginia's Open-Space Land Act, an open-space easement held by a public body to protect natural or open-space values, where open-space land includes land preserved for scenic purposes. A title search shows whether one is recorded against a parcel.
Can the Park Service stop building on private land because it is visible from the Parkway?
No source relied on here gives it that power over private land. The Park Service says it is responsible for preserving important views, including views that extend outside park boundaries, and federal rules against disturbing plants apply on its own land. Private land near the road may carry a recorded scenic easement with its own terms, so the deed, a title search and an attorney answer for a particular parcel.
