Chesapeake Bay: Importance Heritage Resource Concentrations

Overview

This map is a composite picture of designated heritage resources, illustrating the relative concentrations of important heritage hotspots and landscapes. It reflects the local, state and federally designated sites, districts, parks, conservation areas, trails, byways and landscapes which collectively represent the important recognized heritage resources of the Chesapeake watershed.

Data Layer Description

Source

Chesapeake Conservation Partnership

Location

Pennsylvania, New York, Delaware, Maryland, Virginia, West Virginia, and the District of Columbia.

Description

The map displays areas with varying levels of heritage resource overlap related to the Chesapeake Conservation Partnership long-term heritage conservation goal: “Protect the treasured landscapes of our collective heritage from development that would alter the scenery and character that conveys their importance - along our designated trails and scenic rivers and byways, at our parks, and throughout our state and national heritage areas, valued cultural landscapes and historic districts.”

The goal identifies numerous mappable aspects including both designated areas and the resource values on which they are based. Some of these are site specific and others span significant areas within a state or across state lines.

This map is based on the designated areas listed below and described in more detail in the page for the Important Heritage Resources -- Chesapeake Bay Watershed map. For this map the designated areas are treated as follows:

  • National Register of Historic Places: Based on point data of NRHP listings, mostly sites, buildings, objects, and structures, with 30 meter buffer applied for calculating general acreage.
  • National Historic Landmarks: Based on point data of NHL listings on NRHP with 30 meter buffer applied for calculating general acreage.
    • NRHP Historic Districts: Includes area within designated district boundaries.
    • National Historic & Scenic Trails: Includes the length of designated national historic and scenic trails, adding a 30 meter buffer for calculating a general corridor acreage. For the Appalachian National Scenic Trail, the actual land base and a corridor are mapped.
    • ABPP Core Areas: Includes area within Core Areas identified by the American Battlefield Protection Program.
    • National, State, and Local Parks: Includes public land managed as existing county, state, regional, and national parks
    • Publicly Managed Conservation Lands: Includes public land managed as existing state and federal game and wildlife areas, and state and national forests.
    • Scenic Byways: Includes the length of designated state and national scenic byways, adding a 30 meter buffer for calculating a general corridor acreage.
    • State Scenic Rivers: Includes the length of state designated scenic rivers, adding a 30 meter buffer for the linear units to calculate a general corridor acreage. The region has no federally designated scenic rivers.
    • State & National Heritage Areas: Includes area within boundaries of designated state and national heritage areas.
  • Appalachian Trail Landscape: Includes area within landscape identified by Appalachian Trail Conservancy.
  • PA Conservation Landscapes: Includes area within the boundaries of Conservation Landscapes.
  • Maryland Focal Areas Rural Legacy Areas: Includes area within the boundaries of designated Rural Legacy Areas.

All heritage data layers were given a value of “1”, and subsequently stacked, with high overlap areas resulting in higher values versus lower overlap areas with lower values.  The sum of all the heritage data layers resulted in a hotspot landscape that was visualized with a color stretch where the highest values are in red and lower values in green.  

Important caveat: Datasets on many heritage resources included in this map are not fully complete. This map will be revised and updated as additional datasets become available.
