Alternative Text Description for FDOH Septic (Likely)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the locations of likely septic system usage for household wastewater disposal across Florida. The map shows parcel-derived points where properties are determined to likely use septic systems based on data gathered from utilities, state and local government agencies, and other entities with drinking water and wastewater functions. The visualization focuses specifically on locations categorized as having either "Likely" or "Somewhat Likely" septic system usage.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the panhandle region in the northwest extending south to the Keys. Major cities labeled on the map include Jacksonville on the northeast coast, Orlando in central Florida, Tampa and St. Petersburg on the west coast, Cape Coral in southwest Florida, and Miami in the southeast. The map extends north to show portions of neighboring states including Alabama (labeled as "Albany") and Georgia (labeled as "Dothan" and "Valdosta"). The Gulf of America borders the western and southwestern coastline, while the Atlantic Ocean borders the eastern coast. The Straits of Florida are labeled at the southern tip of the state.

KEY INSIGHTS

Septic systems are extensively distributed throughout Florida, with coverage across nearly the entire state except for distinct gaps in major urban centers. The most prominent areas without septic system coverage correspond to major metropolitan areas including Jacksonville, Orlando, Tampa-St. Petersburg, Cape Coral-Fort Myers, and Miami, suggesting these urbanized regions rely on centralized sewer systems. The density of septic system points appears relatively uniform across rural and suburban areas statewide, indicating widespread reliance on individual wastewater treatment outside of city centers. The panhandle region shows particularly dense and continuous septic system coverage with minimal gaps.

VISUAL ELEMENTS

FDOH Septic (Likely)

This layer represents parcels where household wastewater disposal is likely handled through septic systems rather than centralized sewer infrastructure.

Septic System Locations (orange triangles with black hatching)

Appearance:

Orange triangular symbols with dense black diagonal hatching pattern covering each triangle. The triangles appear consistently sized throughout the map.

Distribution:

Septic system points are distributed extensively across the entire state of Florida, covering coastal areas, inland regions, and the panhandle. The distribution follows Florida's land boundaries closely, including barrier islands and coastal peninsulas.

Notable locations:

Dense concentrations appear throughout rural counties in north Florida, central Florida between major cities, along both coasts outside urban centers, and throughout the Keys island chain. Particularly continuous coverage exists in the panhandle region from Pensacola eastward to Tallahassee.

Spatial patterns:

The pattern reveals a clear inverse relationship with urbanization, where septic systems fill areas between and around major cities. Large gaps corresponding to Jacksonville, Orlando, Tampa-St. Petersburg, Fort Myers-Cape Coral, and Miami metropolitan areas create distinct urban voids in the otherwise continuous statewide coverage. Smaller gaps appear around medium-sized cities throughout the state.

Overlapping Patterns

No overlapping patterns of different feature types are present, as this map displays a single thematic layer showing septic system locations.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents a subset of a larger dataset that classifies both drinking water sources and wastewater disposal methods for Florida parcels. The full dataset assigns certainty qualifiers of "Known," "Likely," and "Somewhat Likely" to categorizations. This particular view shows only those parcels classified with the two probability levels indicating likely septic system use, excluding locations with confirmed ("Known") septic systems and those with lower probability classifications. The extensive coverage suggests septic systems remain a dominant wastewater treatment method outside Florida's major urban cores.

DATA CONTEXT

Data Source:

The data is derived from parcel-level points with drinking water source and wastewater disposal method classifications. Information was gathered and processed from multiple sources including utilities, state and local government agencies, and other entities with functions related to drinking water and wastewater management. Each parcel point is assigned wastewater and drinking water values with qualifiers indicating the certainty level of the classification.

Source layer: FLWMI_WELL_SEPTIC_2018

Definition Query:

This map displays a filtered subset of the full dataset showing only parcels where the wastewater (WW) field equals "LikelySeptic" OR "SWLSeptic" (Somewhat Likely Septic). This excludes parcels with confirmed septic systems or other wastewater disposal methods, focusing specifically on locations with probable but not definitively confirmed septic usage.

Scale Information:

The map shows a statewide view appropriate for understanding regional patterns of septic system distribution across Florida. Individual parcel points are visible at this scale, though specific parcel boundaries are not depicted.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The dataset name indicates the data is from 2018, though the exact collection period or temporal validity range is not specified in the available information.

Limitations:

The data represents likely septic system usage based on inference from multiple sources rather than comprehensive field verification. The "Likely" and "Somewhat Likely" qualifiers indicate varying levels of certainty, with these classifications carrying less certainty than "Known" septic locations. Data accuracy may vary by region depending on the availability and quality of source information from local utilities and government agencies.

Map Coverage:

The map extent covers the entire state of Florida including the panhandle, peninsula, and Keys, with small portions of southern Alabama and Georgia visible at the northern border for geographic context.
