Subdividing land into two or more parcels requires interacting with governmental agencies, property owners, developers, engineers, architects, etc. to prepare and process maps through the various city and county agencies. The land surveyors expertise in preparing boundary surveys and subdivision maps, such as Parcel Maps (for 4 lots or less) and Final Maps (for 5 lots or more), could be as simple as splitting one parcel into two or as complex as subdividing several hundred acres into a multi-use land development project of hundreds of parcels. In either situation, the land surveyors knowledge and experience is required to see tasks through to completion.
