About this file
This document package includes survey drawings and sections for a road and wall repair project at Chesapeake and Ohio Canal National Historical Park. The survey drawings depict existing site conditions along Harpers Ferry Road and the adjacent Chesapeake and Ohio Canal Towpath, including topographic information, utility locations, wall and roadway elevations, and other infrastructure details. Cross sections and plan views show stone retaining walls, asphalt pavement, metal guardrails, and other existing site features. Global positioning system control points were established for use in designing repairs to address issues such as deteriorated pavement and walls. The related federal contract opportunity is for repair work at Level 33 along Harpers Ferry Road, with the solicitation issued by the National Park Service under number 140P3022R0021.

1. THIS TOPOGRAPHIC SURVEY IS THE RESULT OF AN
ON-THE-GROUND SURVEY PERFORMED BY VHB DURING
FEBRUARY 2021.
2. SURFACE FOR THE WALL IS BASED ON SCANNING POINT CLOUD
PROVIDED BY NPS. POINT CLOUD WAS ADJUSTED TO MARYLAND
COORDINATE GRID SYSTEM USING FIELD LOCATION OF
SCANNER LOCATIONS. DATA WAS OBTAINED NOVEMBER 10,
2021.
3. PROPERTY LINE SHOWN BASED ON PLAT PROVIDED ENTITLED
"HARPERS FERRY NATIONAL HISTORICAL PARK MARYLAND
HEIGHTS" DATED APRIL 24, 1997 AND PREPARED BY
APPALACHIAN SURVEY, INC. PROPERTY LINE WAS BEST FIT
USING FEATURES SHOWN ON PLAT AND NEARMAP AERIAL
IMAGE DATED MAY 2021. PROPERTY LINE IS APPROXIMATE IN
LOCATION AND DOES NOT REPRESENT AN IN THE FIELD
SURVEY.
4. NO TITLE REPORT WAS FURNISHED, THEREFORE ALL
ENCUMBRANCES UPON THE PROPERTY MAY NOT BE SHOWN.
5. HORIZONTAL DATUM FOR THIS SURVEY IS THE MARYLAND
COORDINATE GRID SYSTEM, NAD 83 (2011). THE VERTICAL
DATUM FOR THIS SURVEY IS THE NAVD88. BOTH DATUMS WERE
ESTABLISHED USING TOP NET LIVE REAL TIME NETWORK
SERVICE. HORIZONTAL REAL TIME CORRECTIONS BASED ON
NAD 83 (2011) AND VERTICAL CORRECTIONS BASED ON GEOID
12B. POINTS WERE ALSO CHECKED USING STATIC GPS
SESSIONS AND PROCESSED USING NOAA OPUS SOLUTIONS.
