FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION

TITLE: PHOSPHORUS RESTRICTIVE BASINS

Geodataset Name:       PHSBAS
Geodataset Type:       SHAPEFILE
Geodataset Feature:    POLYGON
GENERAL DESCRIPTION:
This dataset contains watersheds that have water quality characterized by elevated phosphorus levels and are restricted to the amount of phosphorus that can be imported into the watersheds. Phosphorus can only be applied at agronomic rates.

USER NOTES:
Relied on the integrity of the attribute information within the original data layer.

The dataset consists of 4 watersheds and some specific counties that have high levels of phosphorus in the surface water. As a result, these watersheds have restrictions on the amount of phosphorus that can be imported into the watersheds and applied to the land. The 4 watersheds are Lake Okeechobee, Lake Apopka, the Green Swamp and the Everglades Protection Area (EPA), and the counties include all of Glades, Hendry and Okeechobee.


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:

The Phosphorus Restrictive Basins was created from the drainage basins coverage
(basin-24 (area)).  The watersheds were created by unioning the appropriate
drainage basins in the basin-24 cover.  Some additional modifications
(subtracting and splitting polygons) were made to create the Green Swamp
boundary.  The watershed boundaries for Lake Apopka and Lake Okeechobee area
based on the boundaries established by the Surface Water Improvement and
Management (SWIM) Program.  The boundary for the Everglades Protection Area
(EPA) is based on the Everglades Forever Act (EFA).  The boundary used for the
Green Swamp is describe in chapter 22F-5, Florida Administrative Code.
Process Date: November 2000

Senate Bill 1906 modified Section 373.4595, Florida Statutes (Lake Okeechobee Protection Program) to include all of Hendry, Glades and Okeechobee counties in limiting the land application of phosphorus-containing wastes, including domestic wastewater residuals, septage and animal manure. The extents of Okeechobee, Glades and Hendry Counties beyond the existing phosphorous restricted basins were added to the data set. The new polygons were created by UNIONing the dataset DEP.PHOSPHOROUS_RESTRICTIVE_BASINS in SDE with a subset of the dataset BASE.BOUNDARIES_2M, consisting of the boundaries of Okeechobee, Glades and Hendry Counties. The resulting polygons were aggregated by 'BASIN" and values for the 'BASIN' attribute were entered for each of the new features. Process Date: July 2002
In July of 2004, the GeoPlan Center downloaded this data from the FDEP website (http://www.dep.state.fl.us/gis/datadir.asp) in shapefile format. This following steps were conducted. -added 'DESCRIPT' field based on 'BASIN" -upcased all text in attribute table. Process Date: 20040806
