Surveying:
- Boundary Surveys - This establishes or re-establishes property lines that the Client is paying taxes on, which is a Warranty or Quit-Claim Deed. Any missing property corners are set and intermediate stakes can also be placed on property line. A 18" X 27" Map or Record of Survey is filed in the respective County Courthouse showing the Property lines in relationship to Fences, Canals, Neighboring Deed lines, etc.
- Condominium Plats - This is a Survey performed pursuant to Idaho Code, Title 55 Chapter 15 and determines the Condominium Unit and Common Area location in three dimensions on the Surveyed property according to the applicable statutory procedures regarding the condominium plan and condominium documents.
- Property Dispute Resolution - This is a survey on parcel of land that two or more neighbors are disputing. The Survey hopefully comes to a compromising solution where boundary lines may be adjusted and new Land Descriptions recorded.
- Subdivision Design and Layout - This takes a parcel of undeveloped land and with good planning and our experience, transforms it into Lots, Streets, Parks, and Walkways that make creative use of the land and creates an environment that people want to live in.
- Flood Elevation Certification - This is a survey performed in the regulations as to the FEMA for the purpose of obtaining a building permit or Flood Insurance.
- Commercial and Private Building Site Layout - This type of work involves the Engineering, Design, and stakeout of Parking lots, Storm Water Retention Ponds, Underground Utilities, Building Locations, etc on the Clients property.
- ALTA/ASCM Land Title Surveys - This is one of the most detailed surveys available and must be conducted according to very strict guidelines established by the American Land Title Association, American Congress on Surveying and Mapping and the National Society of Professional Surveyors. It can be as detailed as locating how many parking stalls and underground utilities on a clients property.
- Topographical Surveys - This is a survey that maps the contour of the land along with the accurate location of physical objects including streams, trees, roads, utility lines, buildings, fences, etc.
