Editor's Notes
Historical Perspective
Surveying is the measurement, demarcation, and recordation of land parcels. SGM has been surveying the Roaring Fork Valley and surrounding areas for over 30 years.
Good records are vital to the success of any surveyor. SGM has a wealth of legacy data, experience, and local knowledge.
SGM subdivided many of the larger subdivision in the valley, including Aspen Glen, River Valley Ranch, and the Moore Family PUD to name a few. In short, if there is a subdivision in the Roaring Fork Valley, we have probably surveyed in it.
Surveying has changed drastically in the last 20 years. SGM has kept up with the technology curve, and are experts in the latest surveying technology.
Types of Surveys
Improvement Location Certificate:
(1) A professional land surveyor may prepare an improvement location certificate for the use of a specific client based upon the professional land surveyor's general knowledge of land boundaries and monuments in a given area whether or not the client is the owner or buyer; except that, if the client is not the owner or buyer, the professional land surveyor shall provide a copy of the certificate to the owner or buyer.
(2) (a) (I) A certificate prepared pursuant to subsection (1) of this section shall not be designated as or construed as being a land survey plat or improvement survey plat.
Improvement Survey Plat:
"Improvement survey plat" means a land survey plat as defined in subsection (12) of this section resulting from a monumented land survey showing the location of all structures, visible utilities, fences, hedges, or walls situated on the described parcel and within five feet of all boundaries of such parcel, any conflicting boundary evidence or visible encroachments, and all easements, underground utilities, and tunnels for which properly recorded evidence is available from the county clerk and recorder, a title insurance company, or other sources as specified on the improvement survey plat.
ALTA/ACSM Land Title Survey :
Improvement Survey Plat meeting specific needs, unique to title insurance matters, with associated plats or maps being of a professional quality and appropriately uniform, complete and accurate per the MINIMUM STANDARD DETAIL REQUIREMENTS FOR
ALTA/ACSM LAND TITLE SURVEYS (Effective February 23, 2011). Key elements include a specific certification and Optional Survey Responsibilities and Specifications, Table A.
FEMA National Flood Insurance Program Elevation Certificate
SGM is very familiar with the Elevation Certificate requirements and workflow.
Survey required for Zones A1–A30, AE, AH, A (with BFE), VE, V1–V30, V (with BFE), AR, AR/A, AR/AE, AR/A1–A30, AR/AH, AR/AO.
Survey will accurately place structures within the flood plain, determining type of structure per FEMA, a base flood elevation if available and all relevant and required structure elevations for use in obtaining flood insurance.
Surveys can be relatively easy, or more complex. Depending on size of lot and structure and the defined floodplain in a particular area.
