Low-Altitude Aerial Mapping & Design Survey
Low altitude aerial mapping and topographic/design surveying services to support the engineering design efforts for 3 miles of IH 35. Global Positioning System (GPS) primary control was established along the project followed by panels (secondary control) to control the aerial photography. Aerial mapping at 1” = 20' and a contour interval of 0.4 foot was provided. These mapping files were augmented by on-the-ground survey location of obscured areas, driveways, side streets, visible utilities, drainage structures and right-of-way location. Level C and D Subsurface Utility Engineering (SUE) was also provided. After completion of the field work and compilation of the data, the client was provided with digital files of the planimetrics and the digital terrain model (DTM). Also delivered were hard copies of the survey control for the project and ground survey data.
Natural Resources Conservation Service (NRCS) Wetland Reserve Program
Boundary Surveys
SAM, Inc. provided boundary surveying services for an Indefinite Delivery Indefinite Quantity (IDIQ) A&E services contract to the Natural Resource Conservation Service Wetlands Reserve Program for work within the State of Texas. The contract is for one base year and four option year periods. Task orders include performance of boundary surveys of the WRP/EWP easement area including the route of ingress and egress. All surveys are performed in accordance with the “Minimum Standards of Practice of Land Surveys” as approved by the Texas Board of Professional Land Surveying.
SAM, Inc. has surveyed 9 parcels, totaling over 2,150 acres under the current contract. Metes and Bounds descriptions were prepared for each easement and include GPS coordinates that define the outer perimeter of the easement as well as the route of ingress. Global Positioning Systems (GPS) coordinates were provided based on NAD 83 horizontal datum and GRS 80 spheroid and are represented in Latitude and Longitude (Degrees, Minutes and Seconds). Deliverables included digital data files generated in AutoCAD/LDD .DWG format and 1 original hardcopy and 3 copies of the easement plat signed by the licensed professional land surveyor in addition to certified metes and bound legal descriptions. All boundary surveys are performed in accordance with NRCS standards and SAM, Inc. certifies that all surveys meet NRCS standards.
Lometa Waterline and Impound Structure
Design, Easement Acquisition, Hydrographic Surveys & Construction Layout
Design and easement acquisition surveys were provided for this 9-mile LCRA waterline and impoundment structure project that crossed approximately 13 parcels of land. Fee tract surveys were produced for the water intake and treatment plant sites. General Land Office inundation easements were also provided for the Colorado River Channel. The primary control for this project was established in NAD83(93) HARN coordinates using Global Positioning Systems (GPS), followed by conventional and real-time GPS surveying (secondary control) to control the easement acquisition and design surveying. Design surveying consisted of improvements, topography, visible utilities, drainage structures, trees, and hydrographic surveys of the Colorado River . SAM, Inc. generated a record deed and ownership strip-map based on research of the current ownership information at the local tax appraisal offices. SAM, Inc. also located the right-of-way and boundary line monumentation to establish the boundary lines for 13 parcels of land that required easements. In addition, SAM, Inc. performed construction layout services for this project.
Deliverables consisted of LCRA approved easement acquisition field notes and sketches, digital mapping files including planimetrics, and digital terrain model (DTM) files, overall strip-map of the project, survey control documentation, and various survey exhibits for condemnation proceedings. These projects were delivered in client specific digital format of AutoCAD and Softdesk. All products were prepared in accordance with the LCRA Survey Specifications.
Ft. Boggy State Park
Boundary Survey
This project encompasses approximately 1700 acres of land in Leon County, Texas near the town of Centerville. SAM, Inc. provided a Boundary Survey and Boundary Line Agreement documents for boundary line determination and construction purposes. This Boundary Survey contains 11 separate tracts of land that had not been surveyed since the late 1800's. The survey was performed in conjunction with an extensive ownership research effort. This research included 19 adjacent properties, one U.S. Highway and one Interstate Highway. This research effort was conducted at the Texas General Land Office, the County Appraisal District and Courthouse, various local surveyors and Title Companies and The Texas Department of Transportation.
A combination of traditional and Global Positioning System surveying methods were utilized to complete this project. The client was supplied with AutoCAD digital files and hard copies of all final products.
