Creating Sight Lines Within the RPA

Warning!

Before You Remove Vegetation: 

Approval is required before creating a sight line.
Do not begin clearing, pruning, or removing vegetation within the RPA to establish a sight line until the proposed work has been reviewed and approved by the County.

Contact Environmental Management Before Creating a Sight Line

What is a sight line?

A sight line is a limited opening in existing vegetation that provides a view through a riparian buffer while maintaining the overall environmental function of the buffer. Creating a sight line does not mean clearing all vegetation between a home and a stream, lake, or other feature.

  • Vegetation within the RPA helps slow and filter stormwater runoff, stabilize soil, reduce erosion, and prevent pollutants from reaching nearby streams and waterways. For this reason, sight lines should be created through selective pruning and vegetation removal rather than broad clearing. The goal is to provide a reasonable view while maintaining the environmental benefits of the riparian buffer.

  • When considering a sight line within a Resource Protection Area (RPA), property owners should look for opportunities to preserve as much existing vegetation as possible. Consider the following:

    • Start with areas that are already sparsely vegetated or contain invasive species or dead or dying trees.
    • Prioritize pruning or selectively removing shrubs and understory trees rather than mature overstory trees.
    • Keep the opening as limited as possible while still providing the desired view.
    • Do not disturb or remove groundcover, including woody or herbaceous vegetation, leaf litter, humus, or mulch.
    • Trees removed to create an approved sight line may need to be replaced with vegetation that provides equivalent protection from runoff, erosion, and nonpoint source pollution.
    • County approval is required before pruning or removing vegetation to create a sight line within the RPA.

Virginia's Riparian Buffer Manual allows limited vegetation removal for reasonable sight lines and vistas when approved by the local government, provided the functional value of the buffer is maintained.
