Keeping unused drugs from being misused and reducing the amount of chemicals that reach our waterways are the goals of the pharmaceutical drop off and syringe exchange programs in Boulder County.

This record is maintained in the National Geologic Map Database (NGMDB). The NGMDB is a Congressionally mandated national archive of geoscience maps, reports, and stratigraphic information, developed according to standards defined by the cooperators, i.e., the USGS and the Association of American State Geologists (AASG). Included in this system is a comprehensive set of publication citations, stratigraphic nomenclature, downloadable content, unpublished source information, and guidance on standards development. The NGMDB contains information on more than 90,000 maps and related geoscience reports published from the early 1800s to the present day, by more than 630 agencies, universities, associations, and private companies.

Following the 2013 flood, the Colorado Water Conservation Board (CWCB) initiated a program to re-map the predicted 1% chance regulatory floodplain (100-year flood zone) of the most affected waterways. The program was named the "Colorado Hazard Mapping Program" or "CHAMP." This has been adopted by the Boulder County Commissioners, and will be used for regulatory decisions by the county. Not necessarily used for determining flood insurance.

There is a Boulder County focus inherited from the Boulder Creek Critical Zone program. If you are aware of a resource worth sharing please let us know. Files are in the versatile KML format for ease of sharing. If you have trouble importing these into ArcGIS or another program just let us know.

This digital map shows bedding attitude data displayed over the geographic extent of rock stratigraphic units (formations) as compiled by Colton in 1976 (U.S.Geological Survey Map I-855-G) under the Front Range Urban Corridor Geology Program. Colton used his own mapping and published geologic maps having varied map unit schemes to compile one map with a uniform classification of geologic units. The resulting published color paper map was intended for planning for use of land in the Front Range Urban Corridor. In 1997-1999, under the USGS Front Range Infrastructure Resources Project, Colton's map was digitized to provide data at 1:100,000 scale to address urban growth issues(see cross-reference). In general, the west part of the map shows a variety of Precambrian igneous and metamorphic rocks, major faults and brecciated zones along an eastern strip (5-20 km wide) of the Front Range. The eastern and central part of the map (Colorado Piedmont) depicts a mantle of Quaternary unconsolidated deposits and interspersed Cretaceous or Tertiary-Cretaceous sedimentary rock outcrops. The Quaternary mantle is comprised of eolian deposits (quartz sand and silt), alluvium (gravel, sand, and silt of variable composition), colluvium, and few landslides. At the mountain front, north-trending, dipping Paleozoic and Mesozoic sandstone and shale formations (and sparse limestone) form hogbacks, intervening valleys, and in range-front folds, anticlines, and fault blocks. Localized dikes and sills of Tertiary rhyodacite and basalt intrude rocks near the range front, mostly in the Boulder area.

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.

All roads owned or maintained by Boulder County are contained in the dataset. Additional Colorado State, Federal, Municipal, and surrounding county roads are contained within the data. Roads within Municipalities are not intended to be comprehensive. Non-Boulder County roads were added for reference and context at a scale commensurate with the size of the whole county.

FEMA DFIRM (Digital Flood Insurance Rate Map) base flood elevations effective December 18, 2012, created for Boulder County and all municipalities within under the direction of the FEMA Map Modernization project. This data supercedes all other flood data.Per FEMA: Data included on this CD-ROM represents Final Flood Insurance Rate Map (FIRM) data that has been published as effective FIRM or DFIRM information. The data are the official and legal representation of the effective flood zones.Boulder County added a field, "Regulating Entity" to distinguish this from Boulder County regulatory floodplain.

For use by Boulder County Housing Authority. Data current as of October 2023.

Features within this dataset represent trailheads and/or trail access points are owned and/or maintained by Boulder County Parks and Open Space.

For use in a dashboard to show ARPA funding amounts, communities served, and programs served. Incomplete demographic data for program participants is also shown in a table in the map.

Boulder County crashes mapped from CDOT data. The crash records have a variety of location information, so multiple methods were used to geolocate them, from using lat/long on CDOT roads to geocoding based on the 'Location_x" fields. The records include all mappable crashes starting from January 1, 2021 and ongoing. Hence, this dataset does not include all crash data received from CDOT. Further, historic crash data can be found in the dataset named “Crashes_Historic”.

This data is updated approximately 8 to 12 times per year This layer contains comprehensive street centerlines for Boulder County. Data was developed and is maintained by the Boulder Regional Emergency Telephone Authority (BRETSA).

BCPOS property closures can either be Permanent, Indefinite, or Temporary, depending upon the event and process when the closure was designated.
