Route Survey and Topography. The LAND SURVEYOR will obtain cross-section elevations at 100- foot intervals along the route and extend a distance of 10 feet beyond the respective right of way line. Above ground improvements, including trees lying within 10 feet either side of the existing right of way line will be located. Surface evidence of underground utilities, including valves and manholes, will be located. Invert elevations and pipe sizes will be obtained on all structures along the proposed route.
Route Survey and Topography. Obtain cross-section elevations at 100-foot intervals and all major grade breaks along the route. At each cross-section, spot elevations will be collected at the existing edge of pavement points, the existing roadway centerline, existing right-of-way lines and proposed right-of-way lines. The spot elevation data will be interpolated to depict one-foot contour intervals and will be shown on the survey. Above visible ground improvements, including trees, will be located within the topographic survey limits. Elevations will be referenced to NAVD 88.
Route Survey and Topography. Obtain cross-section elevations at 100-foot intervals along the route and extend a distance of 50 feet west and 60 feet east of the baseline established in the PROJECT’s PER. At each cross-section, elevations will be collected at the existing edge of pavement points, the existing roadway centerline, existing right-of-way lines and proposed right-of- way lines. Above ground improvements, including trees, will be located within the topographic survey limits. Surface evidence of underground utilities will be located. Invert elevations and pipe sizes will be obtained on structures within the proposed route. Elevations will be referenced to NAVD 88. Up to fifteen geotechnical borings will be located and ground elevation will be provided at each boring. The following intersections will be surveyed to obtain existing conditions information within the existing right of way:
