City limits for the City of Boulder, Colorado.

These data layers show the location and boundaries of regulated wetlands within the City of Boulder boundaries based upon field visits to each site. The mapping typically reflects conditions during the specific year and season when the field work was conducted. This data is the official current regulatory area dataset. Created 2017. Combined all previous wetland datasets into one. Query by Status an Category attributes. Status: Regulatory (currently regulated by the city), Non-Regulatory (outside city limits or not regulated by the City), Revised (not regulated - awaiting City Council acceptance), Proposed (wetland application submitted and pending acceptance) Category: Category A - High functioning wetland with 25-foot inner buffer and 25-foot outer buffer (50-feet total). Category B - Low functioning wetland with 25-foot total buffer. Wetland descriptions and evaluations are available on the City of Boulder Wetland Regulation webpage.

Two new species are described from vouchers collected as part of an intensive lichen inventory of Fox Hills Sandstone outcrops in an open space preserve within the city limits of Boulder, Colorado. Candelariella clarkii is characterized by its cryptolecanorine apothecia, chartreuse areolate thallus, and 8-spored asci. Lecidea hoganii is a member of the L. auriculata morphological group characterized by a thick white chalky thallus, pink pigments in the hymenium, and absence of secondary compounds. We provide IUCN conservation assessments for both new species, which should be considered critically endangered. The discovery of two species new to science in a relatively densely populated region of North America illustrates the ecological relevance of small of patches of native habitat, which are certain to become even more important in the future.

The function of the Human Relations Commission (HRC) is to foster mutual respect and understanding and to promote an atmosphere conducive to amicable relations among all members of the Boulder community. The HRC consists of five members appointed by City Council, each to a five-year term. The HRC provides grants for activities which raise awareness on emerging civil rights issues, facilitate interaction, collaboration and understanding between diverse communities and enable community members to celebrate and share culturally diverse events. All activities are run by local non-profits, are free and open to the public and take place within Boulder city limits. The HRC accepts proposals for funding throughout the year, and reviews and awards proposals monthly. While all proposals are funded through the Human Relations Fund, there are designated fund rounds for celebration-specific events such as Dr. Martin Luther King Jr. Day, Celebration of Immigrant Heritage and Indigenous People’s Day. The data contained herein summarizes each request for funding, includes key dates in the award process and summary information about the event organizer and topic. Historical funding request is more limited, as it does not contain information on key dates. In addition, prior to 2017, the Human Relations Fund (HRF) was comprised of two different funds, the Community Events Fund (CEF) and the Community Impact Fund (CIF). Please refer to the data dictionary for a detailed explanation of each data element. The HRC typically holds its business meetings on the third Monday of each month.

This feature represents a standard grid of 20 acre hexagons that anyone can use for visualization and analysis. The location and [row x column] ids will never change, so folks can use this feature for comparisons and analyses over time. The grid covers all of Boulder County and City of Boulder OSMP properties so that any analysis conducted outside of city limits can be done with confidence.Various fields exist to designate whether a grid cell is within city limits, the Boulder Valley Comp Plan (BVCP) boundary, city property, or OSMP property. If a cell has a non-null subcommunity name, that means that it's center is in a subcommunity, or it touches one on an edge. These are areas of interest that are widely used by staff when performing analyses.

This dataset contains required information of City of Boulder Boards and Commissions applicants, including individual's name, address, occupation, and the name of the board or commission in the application. Addresses are used to verify that the individual resides within the city limits of Boulder, which is required to serve on many of the boards and commissions. A data dictionary with descriptions of the fields included in the dataset can be downloaded here.

This data tracks the spatial extent of black-tailed prairie dog colonies on OSMP-managed lands over time, including any held in fee and on conservation easements where the department has a management agreement in place.Data was collected using GPS and clipped to the City of Boulder Open Space and Mountain Parks (OSMP) and Boulder County Parks and Open Space (BCPOS) properties. It has been collected yearly each fall since 1996, by OSMP wildlife staff. Black-tailed prairie dog colonies create a unique habitat on the landscape. They create habitat and food for other animals of federal, state, and local conservation concern (e.g. burrowing owls, ferruginous hawks, bald and golden eagles, American badger, etc., (see the OSMP Grassland Ecosystem Management Plan for more details)). Their burrowing activity also causes conflicts when it occurs on parcels where the management focus is on agriculture or other purposes. The conflict can be especially high in areas of irrigated grasslands since the burrowing activity can alter how water is applied to the landscape, and prairie dog browsing can remove graminoid cover and encourage invasions of tenacious non-native form species. System-wide mapping was first initiated by the mandate to monitor black-tailed prairie dogs in the “City of Boulder Grassland Management: Black-tailed Prairie Dog Habitat Conservation Plan”. This plan was approved by the City of Boulder Open Space Board of Trustees on March 13, 1996. Annual system-wide mapping began that fall, and continued each subsequent fall starting on Sept 1. In 2012 a field was added to distinguish active vs inactive colonies. At this time we began also collecting inactive colony boundaries.The spatial data informs the public, lessees, academic researchers, and partnering agencies as to the extent of the black-tailed prairie dogs on our properties. This data informs conservation planning for sensitive species, including the federally endangered black-footed ferret. The annual mapping can be used to visually demonstrate how populations fluctuate, highlight areas of conflict, and inform management decisions. This long term data set allows for a retrospective view of where prairie dogs have occurred on the system in the past, but where they may no longer persist. This historic view helps staff identify areas where prairie dogs are likely to become reestablished, either through natural recolonization or by direct relocation. Information on where prairie dogs have or do exist also helps inform Habitat Suitability Models. The data set also provides staff with tools to make management decision based on colony management designations (Prairie Dog Conservation Area, Grassland Preserve, Multiple Objective Area, Transition Area, Removal Area (see OSMP Grassland Ecosystem Management Plan for specifics on the designation process)) The data is not meant to estimate the population of individual animals on the system or to estimate colony density.

Dear Commission: I have attached the GeoJSON data for a revised version of the Congressional map that I originally submitted to the Commission in early July 2021. This revised map takes into account the recently-released granular 2020 US Census results. You can also view this new map on Dave's Redistricting website at:https://davesredistricting.org/maps#viewmap::61ea57de-e691-47ad-aa1a-0f4b5eb39eb7I became interested in this process as a mapping and community nerd (rather than a political guru), after becoming aware that the initial preliminary plan cut my home city of Boulder off from the western part of Boulder county. I don't think that is a good idea -- Boulder is so linked to the communities to the west in the foothills up to the Continental Divide, and vice versa. So, I wanted to put my GIS background to work and help the Commission and staff envision alternate configurations of districts which solve that issue.In this new map based on the 2020 Census, I took much greater care to not split municipal boundaries between different districts. All Congressional districts are within +/1 person of the target population. Also, after reviewing a number of the public comments here and ones made during hearings, I put in my best effort to capture several communities of interest in this revised map:1) SLV counties kept whole and associated with district 3 2) Multiple El Paso County military installations all kept together in district 5 3) Continental Divide used as natural boundary for much of the northern Front Range (keeping Boulder, Gilpin, and Clear Creek counties together in district 2 along with all of Larimer Co.)4) Arkansas River valley kept together below Salida (running downslope/east through Pueblo County, etc)5) Northern Douglas County allocated to a southern/western Denver metro district (7th district)6) 7th district is made to be extremely competitive (within 1 point based on the 2016-2020 composite competitiveness score) 7) New 8th district centered solidly in north Denver metro (northern JeffCo, Broomfield, western Adams, far southwestern Weld) 8) Denver City/County kept whole with only minor population-balancing nibblesThank you for your continued work and consideration.Sincerely,Laura J. Westerfield

This geographic dataset was updated by Boulder County Sheriff's Office Communications staff during summer 2023, to be WEA compliant and to provide coverage of all major waterways in Boulder County, including areas of City of Longmont and Town of Erie into Weld County (covered by BRETSA 911). We collaborated with Boulder County Sheriff's Office Law and Emergency Services personnel, Law/Police officials from most legal cities or towns, Boulder County Fire Districts, and Boulder Office of Emergency Management within our Public Safety Answering Point's area of authority that are susceptible to flooding events. This dataset is intended to be a flood hazard set of pre-created areas for reverse 911 notifications, for life safety purposes. The emergency responder (FIRE/LAW) would notify the BOCO 911 Communications Center about which zones to evacuate in the event of a flooding emergency. The 911 dispatch staff could use these pre-created flood hazard polygons to send a reverse notification to the area of interest. Steps to incorporate the areas of flood interest included: 1.) Obtaining new hydrological models for recently burned areas due to 2020 CalWood Fire burn scar; 2.) Utilizing Colorado Water Conservation Board post 2013-flood data (CHAMP) to unerstand updated flood risk; 3.) Meeting with publlic safety stakeholders to review their local areas of interest during collaborative working sessions, incorporating stakeholder feedback; 4.) Applying a 1/8 mile buffer to such areas of modeled interest; 5.) Simplifying edges of flood polygons to be Wireless Emergency Alert compliant; 6.) Importing the data into the emergency reverse notification tool and reviewing the resulting boundaries to ensure citizens are appropriately included in the areas of interest.
