Description: This layer is a polygon layer containing the building outlines based on the 2019 imagery. This is a two-dimensional digital respresentation of the shape of the structure. Structures include - Residential, commercial, and industrial buildings, porches and decks that have a roof, mobile homes, greenhouses, garages, and other features with a roof. The layer does not include docks, cell towers, temporary tents, etcOutlines based on 187,425 parcels (number at contract time). Outlines created October - November 2019
Description: This delivery includes the building outlines created from the 2017 Pictometry imagery. Decks are included in the outlines. The data is link to the PID based on 2018 Tax Year parcel layer
Description: A drainage ditch that funnels stormwater from a given area to a receiving body. Canals have been accepted by Charleston County into our maintenance program and have County jurisdiction to maintain. Canals are not to be edited, added, or deleted by anyone other than Asset Management staff, as approval from Field Operations is required to add or remove a canal from the maintenance program.
Description: This layer contains the bridges maintained by Charleston County Public Works that are not maintained by SCDOTlayer is based on data provided by Public WorksLayer created June 30, 2020

Description: This is a countywide layer that contains the 17 'common' areas that is used in Cartegraph to support the use of Containers in their database. This is the same layer as used by other applications. The layer has been copied into the Stormwater Inventory since it was required to be published as a 'feature service'
Description: Stormwater Inspection Zones maintained by Public Works. Used with Energov to assign Stormwater Inspectors a working area. Last update 02/2024.
Description: The National Hydrography Dataset Plus High Resolution (NHDplus High Resolution) maps the lakes, ponds, streams, rivers and other surface waters of the United States. Created by the US Geological Survey, NHDPlus High Resolution provides mean annual flow and velocity estimates for rivers and streams. Additional attributes provide connections between features facilitating complicated analyses. Published in July 2022.

Description: This shapefile dataset contains vector lines representing streams, rivers, and ditches that were used in preparing the underlying data for the South Carolina StreamStats application. Data were compiled from multiple sources, but principally represent lidar-derived linework from the South Carolina Department of Natural Resources and the South Carolina Lidar Consortium. The South Carolina hydrography lines were created from elevation rasters that ranged from 4 to 10 ft resolution, to produce a product of approximately 1:6,000-scale.Published in 2019.
Description: This layer contains Section 10 waters of South Carolina. Section 10 of the River and Harbor Act of 1899 outlines that federal permits are required when completing construction or dredging projects in or around "navigable waters of the U.S." Section 10 waters are defined as waterbodies that have been navigable in the past, are currently navigable, support interstate commerce, or are tidally influenced. The justification of Section 10 delineation and the USACE Charleston Navigation Study URL are contained in the attribute table.
Description: This layer was derived from the 2017 Charleston County LiDAR delivery. The features were named based on USGS data from the National Hydrography Dataset, ESRI River and Stream data from ArcGIS Online, and USGS Quad paper maps. Updates were completed in December of 2018.

Description: This dataset contains digitized boundaries of intertidal oyster reefs found along the South Carolina coast. The polygons were originally digitized through a combination of automated and manual techniques using 4-band (blue, green, red, near-infrared) digital orthophotos with a theoretical ground resolution of 0.25 meters. The photos were dated from 2003 to 2006. The project area was selected specifically to cover those sections of the SC coastal critical zone where oysters had historically been mapped by the SC Department of Natural Resources (SCDNR). The area spans 122 USGS quarter quadrangles (DOQQs). Sixty of the DOQQs were ground-truthed, by boat, prior to 2011, to assess accuracy. Some areas were verified through photographs taken from low-altitude helicopter flights conducted from 2006 to 2008 by SCDNR. The initial digitization process met the minimum accuracy requirements of the project (80% correct classification) and was completed through a joint effort between Photo Science Inc. and SCDNR. The entire dataset was reviewed by SCDNR for quality using all known information through 2010. Edits and improvements were completed by SCDNR on April 28, 2011. From 2011 through 2015, low-altitude helicopter photography flights were conducted over selected areas of management interest. Photographs from these flights were used as a reference to individually update and edit reef polygons for selected areas.

Description: This dataset contains digitized boundaries of washed oyster shell deposits found along the South Carolina coast. The deposits were digitized through a combination of automated and manual techniques using 4-band (blue, green, red, near-infrared) digital orthophotos with a theoretical ground resolution of 0.25 meters. The photos are dated from 2003 to 2006. The project area was selected specifically to cover those sections of the SC coastal critical zone where oysters had historically been mapped by the SC Department of Natural Resources (SCDNR). The area spans 122 USGS quarter quadrangles (DOQQs). Sixty of the DOQQs were ground-truthed by boat to assess accuracy.

From 2011 through 2015, low-altitude helicopter photography flights were conducted over selected areas of management interest. Photographs from these flights were used as a reference to individually update and edit live oyster reefs polygons for selected areas. Some edits were completed to the washed shell polygons during the editing of the live reef polygon layer. However, the washed shell layer has not received the same level of detailed editing as has the live shell layer.
