Parcel Maps

A Parcel Map is an official map that shows a subdivision of land into four or fewer parcels, sometimes with a “designated remainder.” This map depicts property lines, easements, and monuments set by the Professional Land Surveyor in accordance with the Subdivision Map Act and local ordinance. The map is created to show the locations of each parcel and its relation to surrounding surveys. A Parcel Map is recorded within the county in which the survey is performed, following acceptance by all agencies and governing bodies.

Record of Survey

Record of Survey is a map that shows the location of deed described boundary or easement lines, based on field measurements. Sometimes only a portion of the entire site is shown. This map is reviewed by the County Surveyor for the elements required by the Land Surveyors Act, and then filed within the county in which the survey was performed. A Record of Survey represents the opinion of the Professional Land Surveyor as to the location of those described lines and retracement findings. The Record of Survey also shows sufficient information to locate the survey on the ground, and documents potential title issues related to the specific property lines shown and affected neighboring parcels.

The above two maps were used in court to prove that the owner had planted a vineyard over an equestrian easement. The one on the left was marked on a quad sheet to represent an existing road. The one on the right is a current aerial showing the property.
