Geospatial data about Adams County, Colorado County Boundary. Export to CAD, GIS, PDF, CSV and access via API.

Census tracts are small, relatively permanent geographic entities within counties (or the statistical equivalents of counties) delineated by a committee of local data users. Generally, census tracts have between 2,500 and 8,000 residents and boundaries that follow visible features. When first established, census tracts are to be as homogeneous as possible with respect to population characteristics, economic status, and living conditions. (www.census.gov)

Vector polygon map data of property parcels from Denver, Colorado containing 231,961 features.

Property parcel GIS map data consists of detailed information about individual land parcels, including their boundaries, ownership details, and geographic coordinates.

Property parcel data can be used to analyze and visualize land-related information for purposes such as real estate assessment, urban planning, or environmental management.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

The map and descriptions offer information that may be used for: land-use planning (e.g. selecting land fill sites, greenbelts, avoiding geologic hazards), for finding aggregate resources (crushed rock, sand, and gravel), for study of geomorphology and Quaternary geology. Geologic hazards (e.g., landslides, swelling soils, heaving bedrock, and flooding) known to be located in, or characteristic of some mapped units, were identified.

Surficial deposits in the quadrangle partially record depositional events of the Quaternary Period (the most recent 1.8 million years). Some events such as floods are familiar to persons living in the area, while other recorded events are pre-historical. The latter include glaciation, probable large earthquakes, protracted drought, and widespread deposition of sand and silt by wind. At least twice in the past 200,000 years (most recently about 30,000 to 12,000 years ago) global cooling caused glaciers to form along the Continental Divide. The glaciers advanced down valleys in the Front Range, deeply eroded the bedrock, and deposited moraines (map units tbg, tbj) and outwash (ggq, gge). On the plains (east part of map), eolian sand (es), stabilized dune sand (ed), and loess (elb) are present and in places contain buried paleosols. These deposits indicate that periods of sand dune deposition alternated with periods of stabilized dunes and soil formation.

Thirty-nine types of surficial geologic deposits and residual materials of Quaternary age are described and mapped in the greater Denver area, in part of the Front Range, and in the piedmont and plains east of Denver, Boulder, and Castle Rock. Descriptions appear in the pamphlet that accompanies the map. Landslide deposits, colluvium, residuum, alluvium, and other deposits or materials are described in terms of predominant grain size, mineral or rock composition (e.g., gypsiferous, calcareous, granitic, andesitic), thickness of deposits, and other physical characteristics. Origins and ages of the deposits and geologic hazards related to them are noted. Many lines between geologic units on our map were placed by generalizing contacts on published maps. However, in 1997-1999 we mapped new boundaries, as well. The map was projected to the UTM projection. This large map area extends from the Continental Divide near Winter Park and Fairplay ( on the west edge), eastward about 107 mi (172 km); and extends from Boulder on the north edge to Woodland Park at the south edge (68 mi; 109 km).

Compilation scale: 1:250,000. Map is available in digital and print-on-demand paper formats. Deposits are described in terms of predominant grain size, mineralogic and lithologic composition, general thickness, and geologic hazards, if any, relevant geologic historical information and paleosoil information, if any. Thirty- nine map units of deposits include 5 alluvium types, 15 colluvia, 6 residua, 3 types of eolian deposits, 2 periglacial/disintegrated deposits, 3 tills, 2 landslide units, 2 glaciofluvial units, and 1 diamicton. An additional map unit depicts large areas of mostly bare bedrock.

The physical properties of the surficial materials were compiled from published soil and geologic maps and reports, our field observations, and from earth science journal articles. Selected deposits in the field were checked for conformity to descriptions of map units by the Quaternary geologist who compiled the surficial geologic map units.

The Statistical Neighborhood boundaries were developed in 1970 by the Community Renewal Program (CRP) which was administered by the current Denver Department of Community Planning and Development. Statistical Neighborhoods are typically combinations of census tracts. Geographic place names, such as Windsor and Mar Lee, were assigned to each area and reflect commonly used names of subdivisions and historical parts of the city.

Boundaries as defined by ordinance for City and County of Denver Local Maintenance Districts. A Local Maintenance District (LMD) is formed when a group of neighbors, especially businesses, wish to upgrade the streetscape with special features like special pedestrian lights, benches, flowers, and other such amenities. Properties benefitting by the district pay special assessments to maintain these items. This map shows the boundaries that are defined by a legal description in the ordinance that creates each LMD. It is used by Development Review staff to advise developers about the existence of the LMD and the probability that they will be required to contribute to the annual assessment.NOTE: BENEFITED PROPERTIES, ALSO DEFINED BY ORDINANCE, ARE NOT MAPPED IN THIS LAYER!

The U.S. Census Bureau's year 2000 census block group boundaries for the City and County of Denver. The original census block group boundaries have been adjusted to various Denver GIS data layers to increase the spatial accuracy of this data. Although every effort was made to ensure the accurate rectification of the data, due to geographic problems inherent in the original 2000 census block data, errors may exist. This data-set includes the housing and population data from Summary File 1, and Summary File 3 of the 2000 census. The data-set does not contain data for any enclaves administered by other jurisdictions that are located within the City and County of Denver's boundary.

There are two sources for the subdivision boundary layer. The first is a legacy shapefile of subdivision boundaries which was created and edited separately from the subdivision lots and ownership parcel layers. Due to the independent creation and maintenance of these layers, it is common to see line data separation between subdivision boundaries, lots, and parcels where no legal separation exists. Editing of this dataset more or less ceased at the end of 2010.Beginning in January 2011, new subdivisions have been created and maintained using the ESRI Parcel Fabric data model. In addition, as conditions permit, older subdivisions are re-drawn to original plat and/or City-resurveyed dimensions, and added to the Parcel Fabric dataset. When these older subdivisions are added to the Parcel Fabric, the legacy shapefile representation of the subdivision boundary is deleted.For display on the City website and download from the Open Data Catalog, these two sources are combined into one subdivision layer. Subdivisions based on the Parcel Fabric data model will have a SYSTEM_START_DATE value of January 2011 or later, and will be consistent with underlying lot and parcel data.

This layer represents the geographical divisions of the City and County of Denver that are used by the Animal Care and Control Division to define service areas for Animal Control officers.

This layer is a subset of the zoning boundaries for the City and County of Denver, Colorado to reflect the zone districts in the ‘new code’ that permit general industrial food related activity as a primary use. ‘General Manufacturing, Fabrication, and Assembly’ is a subset of the ‘Manufacturing and Production’ use category (as defined in Section 11.12.5.3). Manufacturing and Production includes manufacturing and production firms involved in the manufacturing, processing, fabrication, packaging, or assembly of goods. Natural, human-made, raw, secondary, or partially completed materials may be used. Products may be finished or semi-finished and are generally made for the wholesale market, for transfer to other plants, or to order for firms or consumers. Goods are generally not displayed or sold on site, but if so, they are a subordinate part of sales. Relatively few customers come to the manufacturing site. More specifically, general manufacturing, fabrication, and assembly includes the following type establishments (Section 11.12.5.3.B.2): a manufacturing establishment primarily engaged in the fabrication or assembly of products from prestructured materials or components; or a manufacturing establishment whose operations include storage of materials; processing, fabrication, or assembly of products; and loading and unloading of new materials and finished products, and does not produce or utilize in large quantities as an integral part of the manufacturing process, toxic, hazardous, or explosive materials. Because of the nature of its operations and products, little or no noise, odor, vibration, glare, and/or air and water pollution is produced, and, therefore, there is minimal impact on surrounding properties. This definition includes all uses or products for Food and kindred products, except those noted as heavy manufacturing. The zoning boundaries data layer is governed by ordinance and is only changed accordingly. Please note: this layer applies to the ‘new code’ only. Zones carried over from the 1956 zoning code, as well as 'DIA', 'OS-A', 'PUD', 'PUD-G' zones, need to be reviewed individually.
