TITLE: BROWNFIELD POLYGON AREAS

Geodataset Name:       BROWNFIELDS_AREAS
Geodataset Type:       SHAPEFILE
Geodataset Feature:    POLYGON
GENERAL DESCRIPTION:
This dataset contains Brownfields areas which are abandoned, idled, or underused industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. Florida's Brownfields Redevelopment Act primary goals are to reduce health and environmental hazards on existing commercial and industrial sites that are abandoned or underused due to these hazards and create financial and regulatory incentives to encourage voluntary cleanup and redevelopment of sites.

USER NOTES:
GeoPlan relied on the integrity of the attribute information within the original data.

Brownfields data is provided to assist in the determination of areas with potential for economic revitalization.

A note concerning data scale:

Scale is an important factor in data usage. Certain scale 
datasetsare not suitable for some project, analysis, or
modelling 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.

1:250000 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 analyses. Every 
effort has been made to supply the user with data 
documentation. For additional information, see the 
References sectionand the Data Source Contact section of 
this documentation. For more information regarding scale 
and accuracy, see our web pages at:

DATA LINEAGE SUMMARY:

Information was obtained from local sources in one of the following formats:
ArcView shapefiles, paper maps, and legal descriptions.

Boundaries from paper maps were digitized over the 1994-1995 DOQQs with various
other existing layers for reference, such as TIGER Roads, USGS Railroads (24k),
and FDOT Local Roads, using ArcView 3.2a

ArcView shapefiles were reprojected and imported into the base polygon shapefile.

Where shapefiles and paper maps were not available, legal descriptions were used
to create the boundaries using COGO (Coordinate Geometry) in ArcInfo 8.0.2

Locational quality information was maintained throughout data development by 
recording the USERNAME, DATESTAMP, and SOURCE for each feature.  See METHOD 
field to determine which process was used to develop each feature.

Graphics and attributes of the original 44 Brownfields current at the time
of data development were visually verified by Camisha Clarke and Carl
Eichenberger and independently QCd by Patrick Pence.

Finally, useful fields from the original database were joined to the polygons.
