A spatial representation of Tax Parcels. Key attributes include KeyPIN. The KeyPIN is the unique parcel identification number used to link the tax parcel to the parcel attributes which are stored and maintained in Oakland County land records.

There is no definite accuracy related to parcel boundaries. The information shown on these maps is for representation purposes only and is not intended to be a legally recorded map or survey. The information was compiled from a number of sources including recorded deeds, plats, tax maps surveys and other public records and data. Users of this data should consult the information sources listed above for verification of the information.

BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. A spatial representation of parcel history. This polygon feature class is created and maintained through the use of a customized tool for parcel maintenance management. As parcel splits and combinations create child parcels, the parent parcels are saved out to the parcel history feature class. Retired tax parcels have been maintained since 1998. Right of way and alley vacations are also maintained in this feature class. Vacations have been maintained since Spring, 2005. The key attributes include parcel identification number (KeyPIN) and the creation date (RevisionDate).

BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. A spatial representation of land use. The polygons contained in this feature class were derived from the Oakland County Tax Parcel feature class. Each parcel was categorized by its land use. When a parcel has multiple land uses, the dominant land use is shown. Assessing records and orthophotography were the main sources used to attribute each tax parcel with land use information. The data was collected in 2021. Key attributes are the land use and key pin (Sidwell number). Land Use stores the Land Use description for each parcel. The Key Pin is the unique Parcel Identification Number (Pin) used to link the parcel to the parcel attributes which are stored and maintained in Oakland County Land Records.

The primary purpose of this data is to be used by Oakland County Planning and Economic Development Services, other County departments, and and local communities for planning purposes. The two major uses are cartographic output and creating summaries at various spatial extents.

The intent of this feature class was to provide a very general representation of a hard copy 1966 land use map. The spatial accuracy and number of vertices used to represent each feature was limited by the intended purpose of the data.

The land use features were heads-up digitized from a 1966 land use map that was scanned and georefereneced using each section corner as a control point. The features were digitized at a scale not greater than 1:15,000, one square-mile section at a time. After the entire county was completely digitized, the features were dissolved based on the Landuse.

Right-of-Way was burned in to the final feature class using the following process. First, the current RoadCenterline feature class was modifed to reflect roads in 1966 using the scanned 1966 land use map and 1963 orthophotography as a reference. Next, the road lines were buffered at specified distanced based on the RoadCode attribute from RoadCenterline to create polygons. Major Roads were split into two types (Perscriptive Easement and Dedicated) based on if the adjacent property was platted prior to 1966. According to the Oakland County Register of Deeds, in 1966 Oakland County was recording documents in liber 120. For the purpose of this feature class it was assumed that simultaneous conveyances recorded in liber 120 or earlier existed in 1966. Major roads that intersected or were adjacent with these simultaneous conveyances were classified as Dedicated and the remainder of Major Roads were classified as a Perscriptive Easement. The buffer distances, representing half the total Right-of-Way width, used for each road code are listed below:

 Minor Road - 30 feet
 Major Road (Perscriptive Easement) - 33 feet
 Major Road (Dedicated) - 46.5 feet
 State Highway - 46.5 feet

U.S. Highway - 46.5 feet Interstate - 60 feet feet

These Right-of-Way widths generally approximate those that actually existed in 1966 and are not intended to indicate the exact width of a specific Right-of-Way. All areas completely surrounded by Right-of-Way such as between directions of travel of a boulevard or interstate or the area inside of a freeway interchange were manually attributed as Right-of-Way.

Water features were burned in the final feature class using a modified version the of the Oakland County Waterbody feature class.
This data was modified to reflect waterbodies in 1966 using the 1966 land use map and 1963 orthophotography as a reference.

Lastly, the features that intersected community boudaries were split using the Identity tool to increase cartographic and analytic performance.

Provided by local CVTs, the special tax districts were created using legal descriptions, maps, or a list of the tax parcel number located within the special tax district. When no description was provided, the school tax code from the parcel attributes was used. The feature class was based on tax parcels, municipal districts and Oakland County roads. The key attributes are Name (the name of the special tax district) and Type (the type of the special tax district).

The DevelopmentAuthority polygon feature class identifies certain types of entities that encourage development/redevelopment in designated areas. This feature class currently represents Downtown Development Authorities (DDA), Tax Increment Finance Authorities (TIFA), and Local Development Finance Authorities (LDFA); however, it will also depict Corridor Improvement Authorities (CIA) and Brownfield Redevelopment Authorities (BRA) in the future. These five types of authorities have the ability to capture tax increment financing (TIF). The features were digitized using legal descriptions, parcel lists, and maps that were provided to the State of Michigan Office of the Great Seal and/or Oakland County Equalization by the authority. The key attributes are Name (official name of the authority), Type (the type of development authority), and DevelopmentPlan (yes/no indicating if the feature represents an area that is part of a development plan and can caputre tax increment financing).Tax Increment Financing is a tool used to promote redevelopment and community improvement projects by channeling funding toward projects in targeted areas. TIF is captured from the increase of property values from a base year. Millage rates from taxing jurisdictions are applied to the increased value. The resulting tax revenue is directed to the authority, rather than the appropriate jurisdiction. Beginning in 1994, taxing jurisdictions have the option to "opt out" of having its taxes captured by the authority. Also since 1994, school taxes may no longer be captured unless they are necessary to make payments on existing eligible obligations. For more information about TIF, see Michigan Department of Treasury's Tax Increment Financing FAQ web page at http://www.michigan.gov/treasury/0,1607,7-121-3218---F,00.html. The State of Michigan has adopted enabling legislation to allow TIF through five types of authorities. Each type of authority has a focus relating to development/redevelopment: Downtown Development Authority (PA 197 of 1975) Correct and prevent deterioration in business districtsEncourage historic preservationPromote economic growth of the districts Tax Increment Finance Authority (PA 450 of 1980)Prevent urban deteriorationEncourage economic development and activityEncourage neighborhood revitalization and historic preservationClosed to new applicants since 1987Allows the development of virtually any type of land use Local Development Finance Authority (PA 281 of 1986)Encourage local developmentPromote conditions of employmentPromote economic growthLimited to business activities involving:ManufacturingAgricultural processingHigh-technology activitiesEnergy productionBusiness incubators Brownfield Redevelopment Authority (PA 381 of 1996)Promote revitalization, redevelopment, and reuse of certain propertyFocus on tax reverted, blighted, or functionally obsolete propertyMDEQ must approve brownfield redevelopment areas Corridor Improvement Authority (PA 281 of 2005)Correct and prevent deterioration in business districtsEncourage historic preservationPromote economic growth of the districtsMust be adjacent to a road classified as an arterial or collectorThese quasi-public entities are created by resolution through a community's governing body. CIA and LDFA boundaries may cross municipal boundaries. In the case of these multi-jurisdictional authorities, both communities must pass resolutions establishing authority. There is currently only one Joint LDFA (Cities of Southfield and Troy) and there are no CIAs in Oakland County. When the community establishes the authority, it must also define the geographic boundaries in which it will operate. DDAs and CIAs are authorized to levy and collect taxes through a special assessment on all properties within the authority boundary. After the authority and its boundaries are established, the authority creates a tax increment financing and development plan. The plan estimates the amount of tax increment financing that will be captured and lists specific projects on which it will be spent. It also defines the development area where the tax increment financing and projects will occur. The development area must be completely within the authority boundary; however, it may be coincident with the authority boundary. An authority may contain multiple development areas, each with its own development and tax increment financing plan. BRAs normally designate development areas as a one or two parcels for a specific development project, while the other types of authorities define development areas as a larger area. Also, LDFAs are only allowed to capture TIF from parcels in a permitted use, such as manufacturing. There may be both eliglible and inelgible parcels within a development area; however, the inelgible parcels do not participate in TIF capture. The base year used to calculate the amount of tax increment financing is set when the development plan is adopted. If the development plan is expanded at a later date, the base year could be reset for the entire development area or the capture could be calculated using multiple base years. The source for the base year was the tax billing code used by Oakland County Equalization. When no tax billing code was available (for communities that don't use the county's assessing system), the community was contacted to obtain the base year. When two separate authorities overlap, each authority can establish overlapping development areas. The authority that first created the development area has first claim on tax increment financing capture. Authority boundaries are represented using multiple features when the development area is not coincident with the authority boundary. One feature represents the development area and a second feature represents the remainder of the authority district that is not part of the development area. Multiple features are also used to represent authorities that have multiple development areas or development areas that have multiple base years. Brownfield Redevelopment Authorities are unique in that the authority boundaries are generally defined as the entire municipality. For this reason, the non-development areas of BRA's have been excluded from this data. The following list shows communities in Oakland County that have established a BRA: City of Auburn Hills City of Birmingham City of Farmington City of Farmington Hills City of Ferndale City of Hazel Park Charter Township of Highland Village of Holly City of Madison Heights Village of Milford County of Oakland City of Oak Park City of Pontiac City of Rochester City of Rochester Hills Charter Twp of Royal Oak City of Royal Oak City of Southfield City of Troy Charter Township of Waterford Source documents for the boundary of each feature were obtained from the State of Michigan Office of the Great Seal, Oakland County Equalization, and the Oakland County Treasurer's office. These could be in the form of a legal description, parcel list, and/or map. For several boundaries, multiple sources were available and conflicted with each other. When this occurred, hierarchy was given to the legal description, then a parcel list, over the map, and the conflict is noted in the Comments field. However, if a parcel was shown in a parcel list, but not described in the authority based on the legal description, then it was still shown in the authority.It should also be noted that legal descriptions were not digitized using exact coordinate geometry. Instead, features were created by referencing the legal description to snap vertices to parcels, right-of-way, section corners, subdivisions, and lots. Features digitized from a legal description or map included road and railroad rights-of-way as it was described or shown in the document.For vague legal descriptions and parcel lists, right-of-way was addressed uniquely for each authority. Some source documents had statements that all or half of the surrounding right-of-way is to be included in the boundary, but some did not address right-of-way at all. In these cases, right-of-way was addressed distinctly for each authority based on the type of authority and the source documents with the method used recorded in the Comments field. The data will be updated on an "as needed" basis when authorities amend their development plans or new authorities are established. Oakland County Equalization and the Oakland County Treasurer's Office will notify and forward the source documents of necessary revisions to Oakland County Planning and Economic Development Services who is the custodian of the feature class. Communities will be contacted annually to verify that the districts have not changed without the knowledge of county departments. In particular, county departments may not be aware of BRA development projects when no TIF is captured. Lastly, because the tax parcel feature class is revised periodically and it is important for the features to be coincident with the tax parcel feature class, the development authority feature class will also be updated annually to correct conflicts due to parcel shifting.

This polygon feature class represents the spatial extent of surficial geology deposits, glacial and sub-glacial drainage, and historical glacial lake shoreline areas in Oakland County. These features were captured using a combination of a surface TIN derived from 10-foot contours and a detailed original map of Oakland County surficial geology by Twenter and Knutilla, 1972. Polygons were delineated on a hard-copy map by John Zawiskie, Cranbrook geologist. The map was then scanned and registered to Oakland County GIS data. The polygons were digitized on-screen. Data was collected at approximately 1:1200; however the original map was produced at a countywide scale. The key attribute is the geologic sediment type.The primary business purpose for the development of this data set was to collaborate with the Cranbrook Institute of Science in producing an educational map about the surficial geology of Oakland County at a scale appropriate to Countywide and sub-County applications. Prior work by Farrand and Bell (1982) mapped surficial geology deposits of the entire state; however the data is too coarse to have meaningful application at a county and sub-County scale. An improved data set was created by combining Oakland's detailed digital topography with a more detailed geology map. Secondary business purposes include natural resources planning and environmental analysis. For example, this map was used to create an aquifer vulnerability map analysis as part of a countywide water resources study conducted by the United States Geological Survey.These features were captured using a combination of a surface TIN derived from 10-foot contours and a detailed original map of Oakland County surficial geology by Twenter and Knutilla, 1972.

Data was collected at approximately 1:1200; however the original map was produced at a countywide scale. Zawiskie QC'd the data through visual inspections of plots, and Nina Misuraca instituted the corrections.
