❑ Viewshed ❑ An area visible from a specific location ❑ Excludes areas beyond the horizon or obstructed by terrain and other features (e.g., buildings, trees). ❑ Data required to calculate a viewshed: ❑ Elevation ❑ Digital elevation model (DEM) - represents the bare earth. ❑ Digital surface model (DSM) - incorporates vegetation, buildings, powerlines and other objects above the bare earth ❑ An observation point or set of observation points ❑ Defines the locations and height from which a person would view a landscape. Viewshed Parameters

Schuylkill River Trail Viewshed Parameters

❑ Based on a Digital Surface Model:

❑ 1-meter resolution, developed from 2006-2008 or 2015 LiDAR data ❑ Trail corridor – DEM values ❑ Observation Points ❑ Placed approx. 42 feet apart ❑ Observer height of approx. 6 feet above the ground ❑ Analysis was limited to 1 mile from the trail ❑ Visible grid cells that overlap forested canopy were expanded by two cells in every direction Parcel Assessment

Parcels within the viewshed were analyzed based upon the following criteria: ❑ Visibility from the trail: Viewshed Area, Visual Magnitude, and Distance ❑ Scenic character within the trail’s viewshed: Landform, Landcover, Water, and Historic/Cultural Resources ❑ Key Observation Points (KOP): Significant views along the trail, identified by project partners ❑ Ownership Fragmentation: Parcel Size and Adjacency to Protected Areas Notes about the Study Methodology: ❑ The methodology was reviewed and approved by project partners ❑ Parcels not within the trail viewshed were removed from the analysis ❑ Each individual trail was evaluated separately Photo: Montco Planning Commission Visibility Resources

❑ Viewshed Area: amount of viewshed area within the parcel ❑ Visual Magnitude: indicates the number of observation points from which the area is visible ❑ Distance: how far the parcel is from the trail

Schuylkill River Trail Scenic Resources

❑ Scenic Resources within the trail’s viewshed ❑ Landform or slope ❑ Landcover ❑ Forested ❑ Wetlands ❑ Hay and pasture ❑ Agricultural crops ❑ Water Resources ❑ Lakes ❑ Rivers/streams ❑ Historic/cultural resources

Schuylkill River Trail Key Observation Points

❑ Significant views along the trail which may contain scenic, cultural or historic features ❑ Identified by project partners ❑ For each KOP the viewshed area and parcel distance was calculated

Schuylkill River Trail Ownership Fragmentation

❑ Parcel size ❑ Adjacency to protected areas

In 2017, a pilot project of an eight mile section of the Schuylkill River Trail was initiated. During the pilot project:

❑ Circuit Trails to include in the full study were determined ❑ A stakeholder list was developed and outreach was conducted ❑ Study methodology was refined and tested ❑ The Wikimapping project for key observation point (KOP) collection was developed ❑ Results of the pilot project were included in a separate report Visual Assessment Project Example 1: Schuylkill River Trail
