This web map created by the Colorado Governor's Office of Information Technology GIS team, serves as a basemap specific to the state of Colorado. The basemap includes general layers such as counties, municipalities, roads, waterbodies, state parks, national forests, national wilderness areas, and trails.Layers:Layer descriptions and sources can be found below.

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.

The City Engineering Quarter Section Map Index contains information regarding City Engineering quarter section numbers and Public Land Survey System (PLSS) information for each quarter section in the City and County of Denver, as well as a few of the surrounding section quarters. For each quarter section of the PLSS in the City and County of Denver, the City Engineering (later the City Surveyor's office) developed and maintained a linen sheet depicting subdivision, lot, ordinance, and easement data in that quarter section. Using Broadway and Colfax Avenue as the dividing lines, the CCD is broken into four quadrants, and the quarter sections for each quadrant are numbered beginning with 1. NOTE: Maintenance of these quarter section sheets was discontinued after 1996 due to the development of the CCD GIS.

Platted parcels of the City of Aurora, Colorado. For ownership parcels, please see the county's GIS parcel data. The City of Aurora, Colorado sits in three different counties: Adams County, Arapahoe County, and Douglas County and lies just east of the City and County of Denver. The city's population was recently estimated over 400,000. Currently, the city is approximately 158 square miles and is annexing land in enclaves and to the east of the city.

Infrastructure, such as roads, airports, water and energy transmission and distribution facilities, sewage treatment plants, and many other facilities, is vital to the sustainability and vitality of any populated area. Rehabilitation of existing and development of new infrastructure requires three natural resources: natural aggregate (stone, sand, and gravel), water, and energy http://rockyweb.cr.usgs.gov/frontrange/overview.htm.

The principal goals of the U.S. Geological Survey (USGS) Front Range Infrastructure Resources Project (FRIRP) were to develop information, define tools, and demonstrate ways to: (1) implement a multidisciplinary evaluation of the distribution and quality of a region's infrastructure resources, (2) identify issues that may affect availability of resources, and (3) work with cooperators to provide decision makers with tools to evaluate alternatives to enhance decision-making. Geographic integration of data (geospatial databases) can provide an interactive tool to facilitate decision-making by stakeholders http://rockyweb.cr.usgs.gov/frontrange/overview.htm.

The purpose of this layer is to provide an accurate representation of impervious surfaces in the City and County of Denver. This layer combines Stormwater Billing impervious surfaces with Planimetric impervious surfaces; allowing for a comprehensive, city-wide, impervious surface layer.This layer is a compilation of two independent sources of impervious surface data. The data is provided by both the City and County of Denver’s Public Works Wastewater Management Division-Customer Service (WMD-CS) and Kucera International Inc.The WMD-CS data represents areas digitized for all stormwater billing inspections after December 2002 and contains impervious surface delineations of each inspected property. These features are updated daily by WMD-CS field investigators and GIS personnel. The planimetric data, supplied by Kucera International Inc, defines the stereocompiled features of the DRCOG Denver Region Urbanized Project Area. The features were compiled from the Denver Regional Aerial Photography Project (DRAPP) 2016 Aerial Imagery Acquisition and Production. This 1"=100' scale imagery is comprised of 4-band RGBIR color orthoimagery with a GSD (Ground Sample Distance) of 0.5'. Imagery was collected with the Leica ADS40 and ADS80 digital sensors and processed with Leica XPro software. Imagery is projected in State Plane Coordinate System, Colorado central zone using the Lambert Conformal Conic map projection parameters. Horizontal and vertical datums are NAD83(11) and NAVD88(GEOID12A) respectively. The planimetric features are static.

City of Aurora, Colorado - Comprehensive Plan 2018: There are 10 place types throughout the city that address common land uses, including residential, commercial, open space, and community facilities. Place types are intended to depict general locations of each place type and not necessarily the land use designation of specific parcels. The City of Aurora, Colorado sits in three different counties: Adams County, Arapahoe County, and Douglas County and lies just east of the City and County of Denver.

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 Office of Emergency Management's warning siren dataset. This coverage contains the locations and attribute data for all warning sirens within the City and County of Denver. Sirens are placed to provide uniform coverage throughout the City and County of Denver, including DIA. The vendor, Federal Signal, developed computer models that took into account topography, atmospheric conditions, structures, and other factors to determine the optimal placement of the sirens. Once the general area was determined; field work finalized suitable areas for exact siren placement. The intent was to avoid obstruction by buildings, locations where the solar panels are blocked by trees, and also to avoid locations such as the front yard of a residential property.

City of Aurora, Colorado easements. Please keep in mind that this easement GIS layer must be paired with City of Aurora parcel GIS layer to show some line work. Also note that the easement layer isn't complete and continues to be worked on. The city's focus is on collecting city owned easements and not on privately owned easements. See disclaimer and terms of use. The City of Aurora, Colorado sits in three different counties: Adams County, Arapahoe County, and Douglas County and lies just east of the City and County of Denver.
