# Alternative Text Description for Box Culverts Map ## TABLE OF CONTENTS - Map Overview - Geographic Context - Key Insights - Visual Elements - Symbol Guide - Additional Information - Data Context ## MAP OVERVIEW This map displays the locations of box culverts throughout Florida as documented in the FDOT Roadway Characteristics Inventory. Box culverts are drainage structures that allow water to pass under roadways. The map shows thousands of individual box culvert locations as point features distributed across the state's transportation network. ## GEOGRAPHIC CONTEXT The map covers the entire state of Florida, from the panhandle region near Pensacola in the northwest to the southern tip near Miami. Major cities labeled on the map include Jacksonville in the northeast, Savannah (Georgia) to the north, Orlando and Tampa in central Florida, West Palm Bay and Palm Bay on the east coast, and Sarasota on the west coast. The map extends to include Montgomery and Dothan in Alabama to the northwest, and Albany and Valdosta in Georgia to the north. The Gulf of America is visible along the western and southern coasts, while the Atlantic Ocean borders the eastern coast. Notable features include Everglades National Park in the south and Dry Tortugas National Park and Great White Heron National Wildlife Refuge in the far south. ## KEY INSIGHTS Box culverts are distributed extensively throughout Florida, with notable concentration patterns corresponding to the state's major transportation corridors and populated areas. The heaviest concentrations appear along the northern panhandle corridor between Pensacola and Tallahassee, throughout the Jacksonville metropolitan area, and across the central Florida corridor connecting Tampa, Orlando, and the Space Coast region. The Tampa Bay metropolitan area shows particularly dense clustering. Southern Florida, including the greater Miami and Fort Lauderdale areas, displays substantial concentrations extending down the southeastern coast. The central interior and southern regions show more scattered distributions, though box culverts remain present throughout most of the state. The pattern reflects Florida's extensive roadway network and the necessity of drainage infrastructure in a low-elevation, high-precipitation environment. ## VISUAL ELEMENTS ### Box Culverts This layer represents the locations of box culvert structures within Florida's roadway system. ### Box Culvert Point Features (magenta/purple circular points) **Appearance:** Small circular points rendered in bright magenta or purple color distributed across the map **Distribution:** Box culverts appear throughout Florida with varying density, present in all regions of the state from the panhandle to the southern tip **Notable locations:** - Dense concentration along the northern panhandle corridor from Pensacola eastward through Tallahassee - Heavy clustering in the Jacksonville metropolitan area and surrounding counties - Substantial concentration throughout the Tampa Bay metropolitan region - Notable presence in the Orlando metropolitan area - Continuous distribution along Florida's east coast from Jacksonville through Palm Coast to Miami - Scattered but consistent presence throughout central Florida - Linear patterns along major transportation corridors connecting urban centers **Spatial patterns:** The distribution follows Florida's roadway network, with linear arrangements along major highway corridors and concentrated clusters in metropolitan areas. Urban regions show dense clustering while rural areas display more dispersed patterns. The heaviest densities occur where major transportation routes converge near population centers. ## SYMBOL GUIDE - **Magenta/purple circular points:** Individual box culvert locations derived from FDOT Roadway Characteristics Inventory data, representing drainage structures that allow water passage beneath roadways ## ADDITIONAL INFORMATION This map represents a single thematic layer extracted from Florida's transportation infrastructure inventory system. Box culverts are critical drainage infrastructure components that manage water flow beneath roadways, particularly important in Florida's low-lying terrain and high-rainfall climate. Each point represents a documented structure location with an associated structure number in the FDOT inventory system. The data reflects conditions as of the most recent inventory collection and may not represent current conditions if recent construction, removal, or modifications have occurred. This map provides a comprehensive view of box culvert distribution across the state's roadway network. ## DATA CONTEXT **Data Source:** The data is derived from event mapping Feature 258, characteristic BOXCULNO from the Florida Department of Transportation (FDOT) Roadway Characteristics Inventory. This represents information collected and reported as of the most recent inventory performed. Data source layer name: BOX_CULVERTS_JAN26 **Definition Query:** No definition query or filter criteria was applied to this dataset. **Scale Information:** The map shows a statewide view appropriate for understanding broad distribution patterns of box culverts across Florida's transportation network. At this scale, individual culvert locations are visible as point features. **Coordinate System:** NAD_1983_HARN_Florida_GDL_Albers (WKID 3087) **Time Period of Content:** The data represents the most recent FDOT Roadway Characteristics Inventory collection as of January 2026. **Limitations:** This data represents conditions as of the most recent inventory and may not reflect current conditions if modifications, additions, or removals have occurred since the inventory was performed. The data is limited to box culverts documented within the FDOT roadway system and may not include structures on local roads not maintained by FDOT or private roadways. **Map Coverage:** The map covers the entire state of Florida and includes portions of neighboring states (Alabama and Georgia) and water bodies (Gulf of America and Atlantic Ocean) for geographic context. --- The alternative text description of this map was AI-generated and may contain inaccuracies. ---
