Its county seat is Washington Court House. Fayette County was formed on March 1, 1810 from portions of Highland County and Ross County. It was named after Marie-Joseph Motier, Marquis de La Fayette, a French general and politician who took the side of the Colonials during the American Revolutionary War and who played an important role in the French Revolution.Fayette County is a part of the Virginia Military survey, which was reserved in 1783, to be allotted to Virginia soldiers. This district includes the entire counties of Adams, Brown, Clermont, Clinton, Highland, Fayette, Madison and Union; and a portion of the counties of Scioto, Pike, Ross, Pickaway, Franklin, Delaware, Marion, Hardin, Logan, Champaign, Clarke, Greene, Warren and Hamilton.Fayette County was formed January 19, 1810 (took effect March 1st) from Ross and Highland counties. Beginning at the southwest corner of Pickaway, running north “with the line of said county to the corner of Madison; thence west with the line of said Madison county to the line of Greene county; thence south with the line of Greene county to the southeast corner thereof; thence east five miles; thence south to the line of Highland county; thence east with said line to Paint Creek; thence in a straight line to the beginning.” All the lower portion was taken from Highland and the upper from Ross.The first portion of land entered within the territory of what is now Fayette county, was a part of original surveys Nos. 243 and 772, lying partly in Clinton county. The first survey lying wholly within Fayette county was No. 463, in what is now Madison township, surveyed for Thomas Overton by John O’Bannon June 30, 1776.The original townships were Jefferson, Greene, Wayne, Madison, Paint and Union. Concord township was formed in April 1818, from Greene. Marion township was formed in June, 1840 from Madison. Perry township was formed June 4, 1845, from Wayne and Greene. Jasper township was formed from Jefferson and Concord December 2, 1845.Washington C.H. was laid out originally on a part of entry 757, which contained 1200 acres and belonged to Benjamin Temple, of Logan county, Kentucky, who donated 150 acres to Fayette county, on condition that it be used as the site of the county seat. The deed of conveyance was made December 1, 1810, by Thomas S. Hind, attorney for Temple, to Robert Stewart, who was appointed by the legislature as director for the town of Washington. The town was laid off some time between December 1, 1810, and February 26, 1811, the latter being the date of the record of the town plat.Bloomingburg (originally called New Lexington) was laid out in 1815, by Solomon Bowers, and originally contained 34 and ¾ acres. On March 4, 1816, Bowers laid out and added twenty more lots. The name of the town was later changed to Bloomingburg by act of the legislature. The town was incorporated by act of the legislature, February 5, 1847.Jeffersonville was laid out March 1, 1831, by Walter B. Write and Chipman Robinson, on 100 acres of land belonging to them, they started selling the lots at $5 each. The town incorporated March 17, 1838. The first house was erected by Robert Wyley.The first railroad, now the C. & M. V., was completed in 1852; the second, now the Detroit Southern, in 1875; the third, now the C.H. & D. in 1879; and the fourth, now the B. & O. S. W., in 1884.The first permanent settler (probably) was a Mr. Wolf who settled in what is now Wayne township, in about the year 1796. - Circa 1886 - Map of Fayette County, Ohio.

This dataset is designed to represent and identify the property boundaries in Lexington-Fayette County. The original dataset was created in late 1990's by a third party that converted existing paper maps to digital GIS files. The data has since been updated by georeferencing recorded plats for corrections and new additions. In cases where the plats do not appear accurate, aerial photos are utilized in attempt to properly locate the property lines. The only except for this process are changes to highway right-of-way in which calls are run from deeds. The geometry of this data is not of survey quality and should not be used for survey purposes. The data is intended for general reference purposes only.As part of the basemap data layers, the parcel boundary map layer is an integral part of the Lexington Fayette-Urban County Government Geographic Information System. Basemap data layers are accessed by personnel in most LFUCG divisions for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on thematic mapping, summarization of data by geography, or planning purposes (including defining boundaries, managing assets and facilities, integrating attribute databases with geographic features, spatial analysis, and presentation output).
Fayette County Ohio GIS Road Centerlines Location Based Response System (LBRS). The information provided is for reference only and subject to independent verification. User assumes all responsibility for its use.https://ogrip.oit.ohio.gov/ProjectsInitiatives/LBRS.aspxOHIO'S LOCATION BASED RESPONSE SYSTEMThe Location Based Response System (LBRS) is an initiative of the Ohio Geographically Referenced Information Program (OGRIP). The LBRS establishes partnerships between State and County government for the creation of spatially accurate street centerlines with address ranges and field verified site-specific address locations.Funding to support the development of LBRS compliant systems is available to counties through a Memorandum of Agreement (MOA) that establishes roles and responsibilities for program participation. Participating counties provide project management and QA/QC on road names, addresses, etc to develop data that is compatible with the state's legacy roadway inventory.The Ohio Department of Transportation is the LBRS Program Sponsor, providing technical guidance, support, and QA/QC services. The program is being administered by OGRIP, the state's coordinating body for Geographic Information System (GIS) activities.Through the collaborative efforts of State and Local government the LBRS program is producing highly accurate field verified data that is current, complete, consistent, and accessible. LBRS data is maintained as an Ohio asset by local resources and is provided to the state as part of a coordinated long-term effort by OGRIP to reduce redundant data collection by developing data that meets the needs of several levels of government.The LBRS supports a multi-jurisdictional approach to protecting the health, safety and welfare of the state’s constituents.LBRS FAQsWhat is the LBRS? The LBRS is a County/State partnership that gathers accurate locational information on all roads and addresses in a county. The information is used to save lives and save taxpayer dollars by reducing redundant data collection activities. The information is web-based, and is therefore current for all stakeholders as agencies or local governments gather new information.Who is using LBRS data? 9-1-1 Dispatch/First Responders, County Auditors, County Commissioners and Engineers, Ohio Highway Patrol/MARCS, County Emergency Management Agencies, Ohio Department of Transportation, US Department of Homeland Security, US Census Bureau, Ohio Department of Natural Resources, Ohio Department of Agriculture, Ohio Utilites Protection Service.“Both disaster planning and emergency response efforts will benefit from the LBRS. By participating, counties may reduce redundant mapping projects while ensuring that Ohio’s citizens do not pay for multiple mapping initiatives.” - Shawn Smith, Ohio 911 Coordinator - Public Utilities Commission of Ohio.How is the state share determined per county? Each county that participates is assigned a ceiling amount, based on number of addressable structures and miles of public roads. The state share does not exceed 50% of the county’s cost of gathering data, and never exceeds the pre-determined ceiling.What other funding sources are available to support a county's LBRS development? The Ohio Department of Transportation (ODOT) and the County Engineers Association of Ohio (CEAO) each administer Safety Grant programs with funds that can be applied to LBRS projects. How are LBRS funds distributed? Counties enter into a Memorandum of Agreement with the state to secure funding. Counties may contract with a vendor or collect information on their own, with OIT/OGRIP and ODOT providing technical guidance throughout the process. Monies are deliverable based, as a County provides data that meets the State defined standards for program acceptance, the monies are released to the County.
The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads Shapefile includes all features within the MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

The urban service area boundary data layer is an integral part of the planning data in the Lexington-Fayette-Urban County Government Geographic Information System. This information is used by the Division of Planning in case review, enforcement, and long range planning. GIS data layers are accessed by personnel in most LFUCG divisions for basic applications such as viewing, querying, and map output production.This dataset is designed to represent and identify the urban service area in Lexington-Fayette County. The urban service area is the part of the county where urban services (city garbage collection, street lights, street sweeping) are provided and a higher density for development is allowed. The boundary is defined by Lexington-Fayette Urban County Council Ordinance. The boundary was originally approved in 1958 and has been occasionally modified. Any expansion to the boundary is considered during Division of Planning's comprehensive plan review process, but the recommendation from Planning must receive Urban County Council approval for alteration. After UCG Council approval is received the ordinance is forwarded to the GIS Office for inclusion in the dataset.The data is in ESRI feature class format, but can be exported to any number of supported formats, including shapefile and dxf. The native projection for the data is Kentucky State Plane North (NAD83), but may have been reprojected for use in other applications. Please check metadata to determine current projection.
