FEATURE ATTRIBUTE TABLES:

Datafile Name: VI_TMDL_RA_FEB17.DBF

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item	Item Description
OBJECTID	Internal feature number.
Shape	Feature geometry.
WBID	Unique Alpha Numeric Water Body Identification. WBIDs make up a are statewide polygon layer in which each polygon has a unique Water Body Identification number (WBID). The assessment units are drainage basins, lakes, lake drainage areas, springs, rivers and streams, segments of rivers and streams, coastal, bay and estuarine waters in Florida. The polygons roughly delineate the drainage basins surrounding the water body assessment units. The WBIDs are used in the Basin Rotation Total Maximum Daily Load (TMDL) program as well as other applications. WBIDs are assigned a FDEP district as part of their attribution. There are multiple instances where a WBID may be assigned to an FDEP district, but physically fall within the boundary of a different district. This is because WBIDs are grouped together into basins called Planning Units and there are instances where a Planning Unit basin will fall across FDEP district boundaries. In these cases, for consistency's sake, all the WBIDs that are in the Planning Unit will be assigned to the same FDEP district. For information on which district the WBID physically falls in, please refer to the FDEP Regulatory Districts layer.
BASIN	The Basin name of the waterbody being assessed.
PU	Name of planning unit, a grouping of WBIDs within a larger basin.
WATER	Name of the waterbody.
GROUP_	Basin Rotation Group number.
TYPE	Waterbody Type.
CLASS	Class of the waterbody as defined in Chapter 62-302.200 and Chapter 62-302.400.
NUTRIENT	Identifies if the waterbody has a verified nutrient impairment (YES/NO).
DO	Identifies if the waterbody has a verified dissolved oxygen impairment (YES/NO).
TMDL	Identifies if FDEP has adopted a TMDL for this waterbody. Unless updated impairment information was provided by FDEP, for water bodies with adopted TMDLs, the impairments listed are the impairments addressed by the TMDL. The water body may or may not still be impaired for those parameters. A project specific determination is needed to determine if nutrient loading calculations are required (YES/NO).
RA	Has FDEP Watersheds Reasonable Assurance Management Plan Status (YES/NO/Not Available = N/A)
NOTES	Notes.
RUN	The last WBID Run Number that is represented by this dataset, please note this may vary by feature.
DATASOURCE	Data Source or Original File Name.
SOURCEDATE	The last date the data was updated by the Source, this may vary by feature.
DESCRIPT	FGDL added field based on the fields WATER and WBID.
FGDLAQDATE	Date FGDL acquired the data from the Source.
AUTOID	Unique ID added by GeoPlan
SHAPE.AREA	Area in meters
SHAPE.LEN	Perimeter in meters

The State of Florida "verified list" of impaired waters is the list of Florida's water bodies that fail to attain any of its designated uses and/or meet the minimum criteria for surface waters established in the Surface Water Quality Standards (62-302, F.A.C.) and the Impaired Waters Rule (IWR, 62-303, F.A.C.). The entire state of Florida is divided into five basin groups in which each water body is re-assessed on a rotating basis every five years. FDEP develops TMDLs for waters on its verified list, or in the alternative, local stakeholders can develop and implement a RAP to restore water quality. The attached lists/maps are for use by consultants to FDOT District 1 to determine if nutrient loading calculations are required. The maps/lists include WBIDs that have a TMDL or are within a RAP watershed and require net improvement. The list is current through the Group 3, Cycle 3 assessments adopted in October 2016.

Watershed Assessment Program Florida's rivers, streams, lakes, estuaries, and coastal waters are spectacularly beautiful. More than that, they are essential natural resources, supplying the water necessary for aquatic life, both large and microscopic; drinking water; recreation; industry; fishing and shellfish harvesting; and agriculture. Florida's multi-billion tourist industry would vanish if our water resources were irreparably degraded. Protecting these abundant water resource, restoring them when they become damaged because of unmanaged growth and development, and preserving them for the future is your responsibility and ours. DEP's Divisions of Water Resource Management and Environmental Assessment and Restoration implement a wide range of programs to protect and restore Florida's surface waters. Tour this website and you will find dozens of different strategies and activities underway to benefit water quality. At the heart of these efforts, particularly in identifying water quality problems and establishing clean-up objectives, is the Watershed Assessment program. https://floridadep.gov/dear/watershed-assessment-section Total Maximum Daily Loads Program What is a TMDL? A TMDL is a scientific determination of the maximum amount of a given pollutant that a surface water can absorb and still meet the water quality standards that protect human health and aquatic life. Water bodies that do not meet water quality standards are identified as "impaired" for the pollutants of concern - nutrients, bacteria, mercury, etc. - and TMDLs must be developed, adopted and implemented to reduce those pollutants and clean up the water body. The threshold limits on pollutants in surface waters - Florida's surface water quality standards on which TMDLs are based - are set forth primarily in rule 62-302, Florida Administrative Code (F.A.C.), and the associated table of water quality criteria. What are the basic steps in the TMDL program? How does it work? 1. Assess the quality of surface waters--are they meeting water quality standards? (Surface Water Quality Standards - Chapter 62-302) 2. Determine which waters are impaired--that is, which ones are not meeting water quality standards for a particular pollutant or pollutants. (Impaired Waters Rule (IWR) - Chapter 62-303) 3. Establish and adopt, by rule, a TMDL for each impaired water for the pollutants of concern --the ones causing the water quality problems. (TMDLs - Chapter 62-304) 4. Develop, with extensive local stakeholder input, Basin Management Action Plans (BMAPs) that.... 5. Implement the strategies and actions in the BMAP 6. Measure the effectiveness of the BMAP, both continuously at the local level and through a formal re-evaluation every five years. 7. Adapt--change the plan and change the actions if things aren't working 8. Reassess the quality of surface waters continuously FDEP is working on a more comprehensive approach to protecting Florida water quality involving basin-wide assessments and the application of a full range of regulatory and non-regulatory strategies to reduce pollution. The TMDL is the heart of this comprehensive approach. https://floridadep.gov/dear/water-quality-evaluation-tmdl/content/total-maximum-daily-loads-tmdl-program

DATA LINEAGE SUMMARY:

Water body ID layer (Run47) was attributed with Verified Impaired Assessment Data, TMDL Data, and RA Data from the Watershed Assessment Section to create the WBIDs impairment dataset. Process Date: 20170216 GeoPlan received the following datasets via email from Janet Hearn of Applied Technology & Management, Inc. on September 11th, 2018. Feb2017Update.gdb - Containing 5 feature classes (1 for each Group) The 5 data sets were received in the following projections: WGS84 and FDEP Albers The projection file was redefined from the FDEP Albers projection to the FGDL Albers projection. For features with WGS84 projection they were reprojected to the FGDL Albers projection. Next the 5 layers were combined and renamed to vi_tmdl_ra_feb17.shp GeoPlan added and populated the following fields: - RA - RUN - DATASOURCE - SOURCEDATE - DESCRIPT - FGDLAQDATE Finally all of the fields and records were uppercased.
