This data represents the graphic portrayal of land parcels and their spatial relationships throughout York County, South Carolina. Land parcel boundaries are also the basis for and define coincident boundaries for other layers, such as zoning, subdivisions, public safety response (ORI -Police, Fire, EMS) and Jurisdiction.Boundaries are established from a variety of sources including cadastral plats, subdivision plats, deeds, land contracts, right-of-way plats, and others. Each feature represents a parcel of land that is inventoried by a unique identifier, referred to as a “Tax Map Id” number. This dataset also includes multi-unit structures which have separate tax accounts for each unit, such as condominium units, represented as stacked polygon features. The parent parcel number [ParentTaxID] for the land parcel is distinguished from the child parcel [TaxMapID] for the condo unit. This data does not include mobile home data. Attributes include data stored within the Esri Fabric data model combined with those from the CAMA data. Examples of relevant attributes include:the [TaxMapID], [ParcelID] and [AprAccNum] can be used to uniquely identify each parcel. the [MailAddr1], [MailAddr2], [MailApt], [MailCity], [MailState], [MailZip] can be used as the full tax billing address for the owner.The [Owner1], [Owner2], [Owner3] describe the owner.the [YearBuilt] offers the oldest year a building was built on the property, reference this web map for info on potential lead pipes on premises;the area of the parcel in acres [GISSizeAC] as calculated from the parcel geometry and also the [deededAcres] from recorded documents, and ;the date that the parcel boundary was last edited [DATE_MODIFIED].How were parcels compiled? This layer was initially developed as an ink-on-mylar property maps maintained by the County from the early 1970's through around 2001.In the 1990s, the county procured services to convert parcels from source documents, however the product delivered in 2000 used a methodology which lost fidelity of source documents. Since then, county staff adhered to this same methodology in their daily work. Between 2001 and 2015 staff used an Esri topology to maintain parcel data in ArcMap. In 2015 the county migrated to Parcel Fabric (ArcMap) and then in 2021 to Pro (2.6/10.8.1 Enterprise) Parcel Fabric. In May of 2021 the county began outsourcing maintenance of parcel edits. This has worked well and was initiated in part to ensure a higher standard of editing practice was adhered to, but also to fulfil a shortage of skilled staff in the job market. County parcel mapping staff remain responsible for simple transactions (merge, split), compilation of materials to create vendor edit request task, and QC or review of vendor work. In Q4 2021, County Staff performed a needs assessment to review alignment issues between parcels and other layers and the internal business requirements for data alignment to parcels. They determined boundary layers must remain coincident with parcels, which are used in decision making by citizens and across many areas of government. Also, it was determined that our parcels had many errors from 20 years of edits in a non-Fabric data model and the previous editing practices. The county will be remapping parcels using ARP grant funding in the 2023-2024 timeframe. Upon delivery in 2024, data maintenance practices will ensure ongoing alignment with parcels.Year BuiltTo obtain the year built for structures on a property, use the 'Buildings' table available through our open data portal.Once you have downloaded the 'Buildings' table and this parcels layer, consider processing the building records in some way to join or perform a relate as there could be many buildings on one parcel, using the following fields:Parcel.AprAccNum = BuildingTable.PropertyID(Note: 98,227 parcels have 1 building, 647 parcels have 2 buildings, 272 have 3 or more)Data SchemaReview the Parcel schema document (PDF) to gain a better understand of the data fields.

The primary use is for e911 public safety dispatch, if a call comes in the dispatcher can review this layer as a guide to look up and then call the provider to have electricity turned off. In January 2022, electric companies (York Electric and Rock Hill) provided indication of service by parcel (presence of an electric meter). The Duke Energy parcels were selected from those unassigned by the other providers, but within the service area regions they provided May 2022. This layer was last updated June 8, 2022 using the more accurate data provided by Duke Energy. Fields were reworked in 2022. There is now a secondary provider attribute that can be populated to suggest the alternative provider for a region, when the area is unknown. This was provided based on the region, for example, if near Rock Hill, the providers might be CRH / YEC / DUKE, if elsewhere, YEC/DUKE are the probable providers. The only exception is the lower left corner near the Broad River, which is Lockhart Power.There may be a small number of properties that are served by multiple service providers, however these are unknown. YEC suggests these are large properties and maybe no more than 3.Annexations in the City of Rock Hill with empty lots become Rock Hill customers. If Rock Hill annexes Duke Energy customers, they remain with Duke Energy. Providers don't appear to communicate between each other about their areas of service. Service areas don’t appear to be regulated.Future updates should take place yearly or at every two years based on the amount of growth.Future updates could focus on areas unknown or may use a different methodology.A note about the Duke Energy Service Area:Duke Energy's Service Area in York County was derived by buffering all of the primary and secondary distribution conductors by 300ft. That buffer was then used to select parcels that intersect with the buffer. Lastly, those selected parcels were dissolved into a single polygon layer and a single record. This process was generated on 5/25/2022. The data product was reviewed internally and released. The information product provided by Duke Energy is not presented in this data, instead it was used to select parcels within the areas provided and assign those as being served by the provider.++++Description last updated 6/8/22++++Access the file geodatabase source data in SC State Plane coordinate system
