A boundary survey is conducted in order to identify the location of land ownership from recorded deeds, wills, plats, road right-of-ways, etc. From this research a surveyor can determine the location of the property. Any missing corners will be reset according to the record deed and boundary lines reestablished.
ALTA/ACSM LAND TITLE SURVEYS
A land survey is made for the Title Company and/or Lender with the survey and location data needed for the issuing of title or mortgage insurance. For this purpose a map is drawn to “ALTA” specifications. "ALTA" stands for American Land Title Association.
ALTA specifies the data to be shown on the survey and this includes boundary lines, location of the main building including improvements, location of ancillary buildings, the identification of easements (access rights by service companies such as water, gas, telephone, railways and other utilities). ALTA surveys are very complex surveys and can cost tens of thousands of dollars and take weeks to complete. For that reason most ALTA surveys are performed on commercial properties.
An ALTA Land Survey guarantees to meet the requirements for an ALTA/ACSM Land Title Survey as detailed by the American Land Title Association, National Society of Professional Surveyors and the American Congress on Surveying and Mapping.
Subdivision Survey is the process of splitting a tract of land into smaller parcels. This shows monumentation and survey data on a map in conformance with the local subdivision ordinance. The subdivision ordinance sets standards for designating residential and commercial lots, roads (rights-of-way), parkland dedication, drainage and utility easements, and how city services will be extended to each lot. These standards are created to improve public health and safety.
Construction surveying stakes out reference points and markers that will guide the construction of new structures such as roads or buildings. These markers are usually staked out according to a suitable coordinate system selected for the project.
TOPOGRAPHIC SURVEYS FOR ENGINEERING AND ARCHITECTRUAL DESIGN
A topographic survey locates natural and man-made features on the subject property. These features are given elevations based on a vertical datum and coordinates based on a horizontal datum. This information is then correlated, contour lines interpolated and then printed onto a piece of paper. These contour lines aid engineers and architects in their design process and enable them to produce a product that will be presented to the developer with little or no negative effect on the environment. After the construction of a building or a new parking lot, rainwater runs off faster, filling streams faster and affecting everyone downstream. If the run off is not controlled the result will be flooding. Parking lots that effectively control runoff after a rain were developed by an engineer who had a good topographic survey furnished by a surveyor.
AS BUILT SURVEYS
This type of survey is conducted to verify that the contractor has constructed buildings, parking lots, drainage areas and other structures according to the design specifications.
FEMA FLOOD CERTIFICATES
A Flood Elevation Certificate is a document generated by an engineer, surveyor, or qualified person that will provide data to help properly rate properties for flood insurance. An Elevation Certificate can determine precisely where your home is located in relationship to the Base Flood Elevation. You should obtain a flood certificate if your property is in a flood zone, or if you are considering disputing it.
