Boundary and Lot Area Checking

After a traverse closure is performed on the boundary and all of the individual lots, the calculated areas are checked against the plat.  Values are calculated to three decimal places for acreage, however only two decimal places are usually shown.  It is not required to show square footage in addition to the acres, however this is at the discretion of the Land Surveyor submitting the plat.  Most local jurisdictions require the individual lot area information on preliminary plats, however Idaho State Code does not require the lot areas to be shown.

Review

·            The area calculated in the boundary closure check is compared to the area shown in the Certificate of Owners.  The boundary closure check value must either match, or must round to the value shown in the Certificate of Owners.  Displaying the value to two decimal places are minimum.  If additional decimal places are shown in the Certificate of Owners, the same criteria apply.

·            If an area table is shown on the face of the plat, it is also checked against the calculated values and the Certificate of Owners.  All must match.

·            If areas for each individual lot are shown on the face of the plat, they are checked against the values calculated for the lot closure.  Individual lot areas are not required by state code (or by local policy) to be shown on a final plat, and it is not recommended that they be shown.
