GENERAL DESCRIPTION:
This dataset contains 2013 Assisted Housing Inventory for the State of Florida compiled by the University of Florida's Shimberg Center. Assisted Rental Housing addresses were gathered from the Florida Housing Data Clearinghouse. The Assisted Housing Inventory (AHI) is a database of multifamily rental developments in the state of Florida that receive assistance under federal, state, and local government funding programs to offer affordable housing units. This dataset contains fields denoting the physical address and other selected attributes for assisted rental units located in Florida. This data is meant to be used for planning purposes only and is not intended to represent a 100% inventory of assisted rental housing. Assisted Housing locations that have been verified are marked with the letter V in the FLAG field. This layer is an update of the previously released FGDL "GC_ASSISTED_HOUSING_FEB09" layer.

GOVP_EXP Overall Expiration Date of Governing Program. If a property has one funding layer, this is the year that the subsidy or period of affordability expires or can be terminated by the owner. If a property has multiple funding layers, several assumptions were made to decide on the most restrictive funding program in terms of income and/or rent restrictions; the year of expiration of the subsidy or period of affordability of the presumed most restrictive funding layer is reported as the overall expiration date.

REAC_SCR REAC Score. For HUD properties, these are the physical inspection scores as assigned by HUD's Real Estate Assessment Center (REAC), and the date that each score was released. Scores are posted from most recent to least recent available from HUD. A score of 60 and above is considered a passing score. The letter 'a' is given if there are no health and safety (H & S) deficiencies; 'b' if there are one or more non-life threatening H & S deficiencies; and 'c' if there are one or more life-threatening H & S deficiencies, also known as exigent or fire safety deficiencies. An asterisk indicates a smoke detector deficiency.

RDATE Release Date. For HUD properties, these are the physical inspection scores as assigned by HUD's Real Estate Assessment Center (REAC), and the date that each score was released.

The Florida Housing Data Clearinghouse (FHDC) was founded in 2000 to 
provide public access to data on Florida's housing needs and supply, 
subsidized rental housing, and household demographics. Sources of the 
data available from FHDC include the U.S. Census, other federal population 
and housing surveys, the U.S. Department of Housing and Urban 
Development, the U.S. Department of Agriculture Rural Housing Service, 
Florida Housing Finance Corporation, local housing finance authorities, 
Public Housing Agencies, the Florida Association of Realtors, the Florida 
Department of Revenue, the Florida Agency of Workforce Innovation, and 
the Bureau of Economic and Business Research at the University of Florida.

The responsibilities of the Clearinghouse include the following:

    Creating a "warehouse" to store data for public use;
    Providing a Web site allowing user-friendly access to all data collected;
    Creating an inventory of federal, state, and locally subsidized housing.
    Preparing an Affordable Housing Needs Assessment for local governments 
    to use in their comprehensive plans;
    Compiling neighborhood-level affordable housing data;
    Preparing an annual State of Florida's Housing report;
    Preparing a statewide rental market study for the Florida Housing Finance 
    Corporation;
    Collecting and sharing data on the housing needs of Florida's special needs 
    populations; and
    Promoting standard formats for collection and sharing of local housing data.

The idea for FHDC originated with the state's Affordable Housing Study 
Commission and was brought into being by a workgroup that included 
representatives from local governments, regional entities, housing advocates, 
the Florida Home Builders Association, the Florida Association of Realtors, 
and state agencies.

The Florida Housing Data Clearinghouse is jointly funded by the Florida Housing 
Finance Corporation (Florida Housing Trust Fund) and the Shimberg Center for 
Housing Studies at the University of Florida, and managed by the Shimberg Center. 



What is Geocoding?
Geocoding is term used to describe the act of address matching.  Geocoding
is the process of finding a geographic location (x, y point) for an address
(such as street number and name, city, state, and ZIP Code) on a map.
Geocoding is based off the typical address scheme for the US, in which one
side of the street contains even house numbers while the other side of the
street contains odd house numbers.

The geocoding process uses an algorithm to find the geographic location
of addresses. First, a street segment is identified using the zip code and
street name. Next, the geographic location of the address is matched using
the building number to determine how far down the street and on which side
of the street the building is located.


Geocoding Accuracy
The locational accuracy of geocoded addresses may vary from urban to rural
areas due to the algorithm used to generate the geographic locations of
addresses. The algorithm assumes that the size of parcels are equivalent
along a road route. This assumption tends to be more consistent in urban
areas, where the size of parcels vary less than in rural areas.
Consequently, the results of geocoded addresses in urban areas are usually
more reliable than those in rural areas.

For example, the locational accuracy of rural addresses can be slightly
off because some parcels along a rural route may be 15 acres while others
may be 2.5 acres, but the geocoding algorithm assumes that the addresses
are distributed evenly along the route.

The data was created to serve as base information for use in GIS
systems for a variety of planning and analytical purposes.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

GeoPlan downloaded this data in an excel format and converted it to a .csv

If a data field is not applicable for a property, this is indicated by a dash (-) in the data cell. 
If a data field is applicable but the data are not available for a property, 
this is indicated by the wording 'not avail.' in the data cell.

The data field records that were populated with a ( - ) were replace 
by the statement NOT APPLICABLE

The data field records that were populated with an ( x ) were replaced
by the statement YES

The data field records that were blank were replaced
by the statement NO INFO

The .CSV file was then converted to .DBF

The dbf was then geocoded with the ArcGIS 10 built-in geocoder and converted 
into a shapefile with the FGDL Albers HPGN map projection. 

There were 2266 records downloaded with the original Excel spreadsheet. 

Fields were renamed and/or truncated to fit within the limitations of the DBF 
format.

During the GeoCoding process 2,242 of these records were matched. 

Once the geocoding process was complete, each record was scrutinized using 
aerials and parcel data. Records that were visually verified were moved to the 
development's interior. Records for which no development could be visually 
verified were not moved and are denoted with a "NV" in the flag field. 

Of the 2,242 records that were successfully geocoded, 2159 were visually verified and moved. 

Once each point was moved the following tasks were undertaken:

- All fields were uppercased
- Added and calculated the USNG1K field
- Added and calculated the LAT_DD field
- Added and calculated the LONG_DD field
- Added DESCRIPT based on NAME
- Added and calculated the UPDATE_DAY field
- Added FGDLAQDATE based on date downloaded from source
