TCAD Calculations on new layer
Turn of all fields except:
PARCEL_ID
PROP_ID
LAND_HSTD_VAL
LAND_NON_HSTD_VAL
IMPRV_HSTD_VAL
MPRV_NON_HSTD_VAL
APPRAISED_VAL
ASSESSED_VAL
HS_EXEMPT
EX_EXEMPT
LAND_ACRES
Select records where all VALUE fields are null and delete
Select records where the land value fields are 0 and delete
LAND_HSTD_VAL = 0 and LAND_NON_HSTD_VAL = 0
Select records where both the homestead and non-homestead land values are not zero. These records are being removed as the exemption is being applied to a portion of the land/improvement, making it difficult to determine what percentage would be applied
LAND_HSTD_VAL <> 0 and LAND_NON_HSTD_VAL <> 0
Add new fields for calculations
LAND_VALUE_TOTAL (double)
ASSE_TO_APPR_VAL_PERCENT (double, numeric: 4 decimal places)
LAND_VALUE_PERCENT (double, numeric: 0 decimal places)
LAND_ACRES_ACTUAL (double, numeric: 4 decimal places)
LAND_SQ_FT (double, numeric: 4 decimal places)
based on LAND_ACRES field, not geometry
Calculate LAND_VALUE_TOTAL field
LAND_HSTD_VAL + LAND_NON_HSTD_VAL
Calculate ASSES_TO_APPR_VAL_PERCENT field
ASSESSED_VAL / APPRAISED_VAL
Calculate LAND_VALUE_PERCENT field
LAND_VALUE_TOTAL * ASSES_TO_APPR_VAL_PERCENT
Calculate LAND_ACRES_ACTUAL field
LAND_ACRES / 10000 (the LAND_ACRES field is not showing actual land acres with the decimal, Matt Leach at WPD verified, double checked on TCAD website looking at parcel land acres)
Calculate LAND_SQ_FT field
LAND_ACRES * 43560
Table to Excel to create export
Must create export as .xlsx as there are 64k+ records
WCAD Calculations on new layer
Turn off all fields except:
PARCEL_ID
PROP_ID
AG_USE_VALUE
ASSESSED_VALUE
IMP_MKT_VALUE
LAND_MKT_VALUE
PROPERTY_MARKET_VALUE
Select records where Value fields are null and delete
Select records where Value fields are 0 and delete
Select records where the Ag. Use Value is not zero and delete. There are currently only 14 records in COA FP. These records don’t follow the standard for exemptions, therefore removing them to remove the anomalies.
AG_USE_VALUE <> 0
Hide this field after deleting records
Add new fields for calculations
LAND_VALUE_TOTAL (double)
ASSE_TO_APPR_VAL_PERCENT (double, numeric: 4 decimal places)
LAND_VALUE_PERCENT (double, numeric: 0 decimal places)
LAND_SQ_FT (double, numeric: 4 decimal places)
based on LAND_ACRES field, not geometry
Calculate LAND_VALUE_TOTAL field
LAND_MKT_VALUE (adding new field to match TCAD fields)
Calculate ASSE_TO_APPR_VAL_PERCENT field
ASSESSED_VALUE / PROPERTY_MARKET_VALUE
Calculate LAND_VALUE_PERCENT field
LAND_VALUE_TOTAL * ASSES_TO_APPR_VAL_PERCENT
Calculate LAND_SQ_FT field
Calculate geometry to area, square feet, state plane
WCAD does not share land acres in data, therefore must use parcel geometry

Create export as .xlsx to match the TCAD export
