What is ISP or LSP?

An Improvement Survey Plat is the same as a Land Survey Plat resulting in a monumented land survey showing the location of all structures, visible utilities, fences, hedges, or walls situated on the described parcel and within 5 feet of all boundaries of such parcel, any conflicting boundary evidence or visible encroachments, and all easements, underground utilities, and tunnels for which property evidence is available from the county clerk and recorder, a title insurance company, or other sources as specified on the Improvement Survey Plat.

A Monumented Land Survey means a land survey in which monuments are either found or set pursuant to sections 38-51-103, 38-51-104, and 38-51-105 to mark boundaries of a specified parcel of land.

  3. All field measured dimensions and platted or deeded dimensions.

Recording Plats:

Every PLS who accepts a monument while performing an ISP shall prepare and deposit a plat if such monument is not of record either in the clerk and recorder’s office or if set monument is set pursuant to section 38-51-104. (12 Months)

No plat shall be required to be recorded if the monuments accepted or set are within a platted subdivision that was filed within the previous twenty years.
