Alternative Text Description for FDOH Septic (Known)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays known septic system locations across Florida based on parcel-level data. The map shows individual properties that use septic systems for domestic wastewater disposal, with a high level of certainty based on verified information from utilities, state and local government, and other entities. The distribution reveals the widespread use of onsite septic systems throughout the state, particularly in areas outside of centralized sewer service.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from the Georgia and Alabama borders in the north to the Florida Keys in the south. Major cities labeled on the map include Jacksonville on the northeast coast, Orlando in the central region, Tampa on the west-central coast, Miami in the southeast, and Cape Coral in the southwest. The map also shows portions of neighboring states including Dothan and Albany to the north and Valdosta to the northeast. The Atlantic Ocean borders Florida to the east, and the Gulf of America borders the state to the west and south. The Straits of Florida are labeled at the southern tip of the state.

KEY INSIGHTS

The map reveals extensive septic system use throughout most of Florida's land area, with notable white gaps indicating areas without known septic systems. The heaviest concentration of septic systems appears across northern Florida, extending from the Panhandle through Jacksonville. Central Florida shows dense septic system coverage across a broad swath of the state, including areas around Orlando. Significant concentrations also appear in southwest Florida near Cape Coral and Fort Myers, and throughout the Florida peninsula. The white gaps are most prominent in urban cores of major cities including Miami, Tampa, Orlando, and Jacksonville, suggesting these areas have centralized sewer systems. Coastal areas show mixed patterns, with some sections having dense septic coverage while others show gaps. The Florida Keys at the southern tip display a distinct line of septic systems extending into the ocean, likely representing developed islands.

VISUAL ELEMENTS

FDOH Septic (Known)

This layer represents individual properties in Florida that are confirmed to use septic systems for wastewater disposal.

Known Septic Systems

Appearance:

Individual locations are represented by dark reddish-brown triangular symbols arranged in a dense pattern across the state. The triangles create a textured appearance where coverage is continuous.

Distribution:

Septic systems are distributed across nearly all land areas of Florida, with particularly dense coverage in northern, central, and southwest regions of the state.

Notable locations:

Spatial patterns:

Septic systems cluster most densely in rural and suburban areas, creating nearly continuous coverage across large portions of the state. White gaps form distinct voids in the coverage pattern, primarily corresponding to urban centers where centralized sewer infrastructure exists. The boundary between septic-served areas and non-septic areas often follows municipal or service district boundaries. Coastal development patterns are visible where septic systems line the shoreline in some areas but are absent in others. The distribution suggests septic systems are the dominant wastewater treatment method outside of major urban centers.

Overlapping Patterns

The interface between dense septic coverage and white gaps creates a clear delineation between areas served by onsite wastewater treatment and those served by centralized sewer systems. This pattern reveals urban-rural infrastructure differences across Florida.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map displays only the "Known Septic" category from a larger dataset that includes multiple levels of certainty (Known, Likely, and Somewhat Likely). The points shown represent the highest confidence level where septic system presence has been verified through authoritative sources. Each point represents a parcel-based location rather than the precise location of the physical septic system infrastructure. White areas on the map may include properties served by centralized sewer systems, properties with other wastewater disposal methods, or areas where septic system status could not be verified to the "known" confidence level. The map reveals the scale of Florida's reliance on decentralized wastewater infrastructure across much of the state.

DATA CONTEXT

Data Source:

The data is compiled from multiple authoritative sources including utilities, state and local government agencies, and other entities with functions related to drinking water or wastewater infrastructure. Information was gathered and processed to create parcel-derived points, with each location assigned values for both wastewater disposal method and drinking water source. A qualifier system (Known, Likely, Somewhat Likely) was applied based on the level of certainty from the source information. This map displays only locations where the wastewater disposal method is confirmed as septic with the highest confidence level. Source layer: FLWMI_WELL_SEPTIC_2018.

Definition Query:

The map is filtered to show only records where the wastewater field equals "KnownSeptic," representing locations with verified septic system use based on authoritative source data.

Scale Information:

The map is displayed at a statewide view appropriate for understanding broad patterns of septic system distribution across Florida. Individual triangular symbols are visible at this scale, though precise parcel boundaries are not shown.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The data is from 2018 based on the source layer name FLWMI_WELL_SEPTIC_2018.

Limitations:

This map shows only "Known Septic" locations where verification was possible through available sources. Additional septic systems may exist but are not displayed if they could not be confirmed to the "known" certainty level. The data represents conditions as of 2018 and may not reflect more recent infrastructure changes, new development, or connections to centralized sewer systems. Points are parcel-derived and may not represent the exact physical location of septic system components.

Map Coverage:

The map extends across the entire state of Florida and includes portions of neighboring states (Georgia and Alabama) and waters (Atlantic Ocean, Gulf of America, and Straits of Florida) for geographic context.
