LOT AND BLOCK (RECORDED PLAT) METHOD
Subdivision plat map 
/ Description format
Subdivision plat map The recorded plat method, also called the lot and block system, is used to describe properties in residential, commercial, and industrial subdivisions.
Under this system, tracts of land are subdivided into lots. The entire group of lots comprises the subdivision. In a large subdivision, lots may be grouped together into blocks for ease of reference. The entire subdivision is surveyed to specify the size and location of each lot and block. The surveyor then incorporates the survey data into a plat of survey, or subdivision plat map, which must comply with local surveying standards and ordinances.
If local authorities accept it, the subdivision plat map is recorded in the county where the subdivision is located. The recorded lot and block numbers of a subdivision parcel, along with its section, township and meridian reference, become the property’s legal description. The exhibit shows a sample subdivision plat map.
Description format The description of a recorded plat property first presents the property’s lot number or letter, then the block identifier and the subdivision name. Note that this is only a portion of the full legal description, which must describe the subdivision’s location within a section, a township, a county, and a state. For example, if the subdivision in the exhibit is situated in the southeast quarter of Section 35 of Township T28S, R19E, of the Tallahassee Principal Meridian, the legal description of the lot marked “7” would be:
“Lot 7, Block 8 of the Grand Oaks Subdivision of the SE 1/4 of Section 35, Township T28S, R19E of the Tallahassee Principal Meridian in Pinellas County, Florida.”
