Right of Way Survey and Right of Way Acquisition
Right of Way Survey and Right of Way Acquisition


Right of Way Survey and Right of Way Acquisition, collectively known as Right of Way Engineering, consists of the research, surveying, mapping, and documentation required to purchase land as a necessary component of a project.  The following activities are necessary components of a complete and accurate Right of Way Engineering services:

  • Determine all right of way needs for the project, including easements (permanent and temporary), utilities and acquisition information, and other right of way information necessary to accomplish the project.
  • Prepare the existing conditions land-net for the project.
  • Perform field surveys.
  • Perform research and analyze existing records for the fee parcel boundaries and existing right of way conditions.
  • Gather title reports and supporting documents.
  • Prepare a boundary analysis report summarizing the methods and findings for preparing the existing conditions right of way and boundary mapping.
  • Prepare appraisal mapping.
  • Prepare descriptions and exhibits for easements, permanent acquisitions, and right of way documents.
  • Stake site to assist appraisers durign the right of way acquisition process.
Hydrographic and Bathymetric Surveys

 

A Hydrographic Survey prvides a three-dimensional picture of underwater features in the survey area, which can affect channel flow rates, detention storage capacities, marine construction, maritime navigation, and dredging.

Topography Survey and Topography Mapping
Topography Survey and Topography Mapping

 

A Topographic Survey is a survey locating topographic features - natural and man-made - such as buildings, improvements, fences, elevations, trees, streams, contours of the land, etc. This type of survey may be required by a governmental agency, or may be used by engineers and/or architects for design of improvements or developments on a site.

Most Land Surveyors use electronic distance and angle measuring equipment, as well as the traditional transit and tape. Modern computer systems aid in efficiently gathering measurements and in evaluating all collected evidence required to perform the survey. Global Positioning Systems (GPS) or "satellite surveying" can provide greater accuracy and efficiency for some surveys. The Land Surveyor takes pride in using these instruments and computers to perform land surveys efficiently, accurately and cost effectively.

Subdivision Survey
Subdivision Survey

 

A Subdivision Survey is the survey and mapping required to divide a subdivision of a tract of land into smaller parcels, showing monumentation and survey data on a map, in conformance with local ordinances and the Subdivision Map Act.

Site Planning Survey
Site Planning Survey

 

A Site Planning Survey is a combination of boundary and topographic surveys for preparation of a site plan to be used for designing improvements or developments.

Lot Line Adjustments
Lot Line Adjustments

A Lot Line Adjustment is a process which allows minor changes in lot shape or size to be completed without the need for a more complicated subdivision application. The lot line adjustment process allows a property owner to change the shape or size of a lot by simply repositioning the existing lot lines.

GPS Control
GPS Control

Global Positioning Systems (GPS) or "satellite surveying" can provide greater accuracy and efficiency for some surveys. While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military. GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time.

GIS Mapping
GIS Mapping

 

●    Simply put, a GIS combines layers of information about a place to give you a better understanding of that place. What layers of information you combine depends on your purpose, finding the best location, analyzing environmental damage and so on.

 

Elevation Certificates
Elevation Certificates

An Elevation Certificate is a form that is used by the NFIP (National Flood Insurance Program) to provide supplemental information found on a FIRM (Flood Insurance Rate Map). It is used to provide a comparison of an actual elevation (determined by field measurement) to the Base Flood Elevation data that is associated with some Special Flood Hazard Areas. An elevation certificate can be used to provide information necessary to ensure compliance with community floodplain management ordinances, to determine the proper flood insurance premium rate, and/or to support a request for a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR). Only a LOMA or LOMR from the Federal Emergency Management Agency can amend a Flood Insurance Rate Map and remove the Federal requirement that a lending institution require the purchase of flood insurance. Note that the lending institution may still require flood insurance without regard to the lack of a Federal requirement.

The fieldwork necessary to complete an elevation certificate involves the determination the actual elevation(s) of reference point(s) of the structure and the elevation of the adjacent grade. Which reference points are necessary is dependent on the type of structure (on slab, basement, or piers) and other characteristics as outlined on the certificate. The form will also require the base flood elevation information as published on the Flood Insurance Rate Map.

Court Exhibit Survey
Court Exhibit Survey

A Court Exhibit Survey provides analysis of various legal descriptions and survey maps; field locating existing monuments, and physical features; and mapping showing this information for the purpose of presenting a visual exhibit to be used in a courtroom.

Construction Survey and Staking
Construction Survey and Staking

 

A construction survey provides construction staking of improvements shown on improvement plans for control of construction on developments for roads, buildings, pipelines, etc.

Control Networks
Control Networks

 

A control survey provides an accurate location of horizontal and vertical positions of points for use in boundary determination, mapping from aerial photographs, construction staking, and other related purposes.

Boundary Survey and Mapping
Boundary Survey and Mapping

A boundary survey is a survey for the purpose of locating the corners, boundary lines and/or easements of a given parcel of land. This involves record and field research, measurements, and computations to establish boundary lines in conformance with the Professional Land Surveyors Act.

ALTA Survey and Exhibits
ALTA Survey and Exhibits

 

An ALTA survey is a boundary survey prepared to a set of minimum standards that have been jointly prepared and adopted by the ALTA/ACSM (American Land Title Association and American Congress on Surveying and Mapping). Additionally, an ALTA survey shows improvements, easements, rights-of-way, and other elements impacting the ownership of land. An ALTA Survey is often prepared for commercial properties, as it will provide the title company with the information required to insure the title to the land and improvements to the high degree that a commercial development may require.

Aerial Photogrammetry and Topographic Mapping
Aerial Photogrammetry and Topographic Mapping

 

Aerial Mapping combines a high-quality control survey with high-resolution imagery to create  topographical features.  Combined with traditional survey techniques, aerial mapping provides a complete overview of the survey area that can be used to generate contours and create a design-caliber digital terrain model.

3D Laser Scanning Surveying
3D Laser Scanning Surveying

 

3D Laser Scanning provides a detailed three-dimensional map of the surface scanned, taking both horizontal and vertical position data while also capturing data about the color, reflectivity, and texture of the surface scanned.  The product of a 3D Laser Scan is a highly detailed, geometrically precise three-dimensional model of the existing physical environment of the area scanned.  3D Laser Scans also collect significantly more data than traditional survey techniques, which can limiting the costs associated with gathering data outside of the original parameters of the survey requested.
