Below is information for the housing (H-xxxxxxxx.dbf) file. Each field name and expected values are described below.

This information is used to generate an Initial Damage Assessment - Housing Losses (EM39 REV.9/90)
form required by the Federal Emergency Management Agency (FEMA) for emergency assistance.

Field Name
Rec_num
Explanation
Each row of information entered has a unique ID number based on date and record number. For example, the first record entered on May 4, 1999, will have a rec_num = 050419991. The fifth record entered on the same day will have a rec_num value of 050419995. This number is automatically generated by the application.

Field Name
PID
Explanation
Pid represents the parcel (or property) identification. This is one of the four values that will be populated automatically from the user's  parcel database. It represents a unique identification number that usually comes from a land record, or tax assessors database.

Field Name

Rcn is an abbreviation for  Replacement Cost New. Rcn represents the monetary value of the structure. This is one of the four values that will be populated from the user's  parcel database. If the property value is not in the database the user will be informed of this and will be given the option to enter a value; if unknown the system will automatically code the Rcn value -9999.

Field Name
Percent
Explanation
Percent represents the percent of damage to the home, as determined by the assessor.

Field Name
Estloss
Explanation
Estloss represents estimated loss to the home. This value is taken by multiplying the value of the home by the percent damaged. For example, a home with a value (Rcn) of $100,000, estimated to have 10 percent damage (Percent) will  have an estloss value of $10,000. This value is automatically generated by the application.
 

Field Name
Home
Explanation
Home can contain one of three choices: primary, secondary, or no entry. Primary indicates that the home is occupied more than 50 percent of the time by the owner. This information is entered by the damage assessor.

Field Name
Status
Explanation
The Status field will indicate whether the home was owned or rented. This information is entered by the damage assessor. The choices are rent, own or no-entry.
 

Field Name
Damages
Explanation
The Damages field will have three choices. (1) "Minimum" represents physical damages representing 10 percent or less of the home's replacement cost or fair market value. Minimum damages are those which will require minimal repairs to doors, windows, floors, utilities, etc., to make the structure habitable again. (2) "major" represents between 11 to 74 percent of the home's replacement cost or fair market value; this includes a home with extensive damages to its foundation, roof, and walls. (3) "Destroyed" is a property that is uninhabitable and sustained damages equaling or exceeding 75 percent of the home's replacement cost or fair market value. Reconstruction or relocation are the only options to restoring the home to its original use. This information is calculated by the application. This value is based on the percent of damage that is entered with the tool during the assessment.
 

Field Name
Iso
Explanation
Iso is an abbreviation for isolated. Even if the home may not have sustained any physical damages, the structure is considered unusable if the home is no longer accessible or if there is a lack of essential utilities such as electricity or water. This field will contain a yes, no, or no entry. This information is entered by the damage assessor.

flood waters entered the home. This information is entered by the damage assessor.

Field Name
This entry on the hard copy form should remain blank, for state use only. The three choices are rt, hr, and no entry. Mark as no entry.
 

Explanation
Selected
Field Name
Selected is a value generated by the application. The possible choices are enmasse or solo. Enmasse indicates that multiple parcels were selected and entered at the same time during the damage assessment. Solo indicates only one property was selected at a time and entered. This information is useful as it gives the assessor an opportunity to re-visit the database and correct or update information that was added when multiple parcels were processed at once. This would be important as multiple parcels entered at once will have some default values entered into the *.dbf file that perhaps would need to be changed later.
