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)

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!

Municipal boundaries in the Denver Region in 2024. Discrepancies between municipalities along county boundaries resolved using "agreement points" from the Colorado North Central Homeland Security Region (NCR) as a guide. The NCR "agreement points" are agreed upon locations between counties where a road enters/leaves their jurisdiction. Boundaries were not necessarily snapped to the NCR agreement points.

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Denver Basin Province is located in eastern Colorado, western Nebraska, southern South Dakota, and eastern Wyoming encompassing all or parts of Pueblo, El Paso, Crowley, Lincoln, Kit Carson, Elbert, Teller, Douglas, Jefferson, Denver, Arapahoe, Adams, Washington, Yuma, Morgan, Weld, Broomfield, Boulder, Larimer, Logan, Sedwick, Freemont, and Phillips Counties in Colorado. All or parts of Cheyenne, Deuel, Kimball, Banner, Scotts Bluff, Morrill, Garden, Sheridan, Box Butte, Sioux, and Dawes Counties in Nebraska. All or parts of Laramie, Platte, and Goshen Counties in Wyoming, and all of parts of Custer, Fall River, and Shannon Counties in South Dakota. The main population centers within the study area are Denver, Colorado Springs, Fort Collins, and Greeley Colo.; Cheyenne, Wyoming, and Scottsbluff, Nebraska. The main highways, I-70 and I-80 generally traverse the area from east to west, while I-25 generally traverse the area from north to south. The province boundary was drawn to include the geologic structures generally considered to be in or bounding the Denver Basin.

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.

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 plant husbandry as a primary use. ‘Plant Husbandry’ is defined as an agricultural use, other than a plant nursery, in which plants are cultivated or grown for the sale of such plants or their products, or for their use in any other business, research, or commerce; excluding, however, forestry and logging uses. Additional information on plant husbandry can be found in Section 11.12.6 in the official zoning code. 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.
