Description

The Boulder County Comprehensive Plan (BCCP) was developed to respond to the widely accepted principle that the myriad of future land use decisions affecting the county’s lands should be made in a coordinated and responsible manner.

BCPP’s philosophy is that:
* Growth should be channeled to municipalities.
* Agricultural lands should be protected.
* Preservation of our environmental and natural resources should be a high priority in making land use decisions.

Boulder County values and strives to preserve, conserve and restore the unique and distinctive natural features, ecosystems and landscapes of the county using sound resource management principles and practices at both a site‐specific level and on a broader, landscape scale. Boulder 
County's important environmental resources include naturally occurring ecosystems and their native species populations. Species of Special Concern are an integral component of this management approach. The list of Species of Special Concern includes locally threatened or endangered flora and fauna that the county seeks to protect. Habitat for these Species of Special Concern is particularly vital, since it often presents our best chance to protect native species.  

Boulder County Comprehensive Plan Environmental Resources Element Approved by Planning Commission 6/19/2013    Overview    Boulder County values and strives to preserve, conserve and restore the unique and distinctive  natural features, ecosystems and landscapes of the county using sound resource management  principles and practices at both a site‐specific level and on a broader, landscape scale. Boulder  County's important environmental resources include naturally occurring ecosystems and their  native species populations. Species of Special Concern are an integral component of this  management approach. The list of Species of Special Concern includes locally threatened or  endangered flora and fauna that the county seeks to protect. Habitat for these Species of  Special Concern is particularly vital, since it often presents our best chance to protect native  species.     In addition to identifying Species of Special Concern, this Element designates areas of important  habitat at two scales: the “site‐specific scale” and the broader, “landscape‐scale.” At the site‐ specific scale, important environmental resources typically consist of an easily definable area  such as an individual parcel of land or a distinct geographical location where specific resources  exist. Designations at the site‐specific scale include Critical Wildlife Habitats, Rare Plant Areas,  Wetlands, Riparian Areas, and Significant Natural Communities (formerly referred to as Critical  Plant Associations). Environmental resources designated at the landscape‐scale are much larger  and holistic in approach. At this scale, the designations of High Biodiversity Areas and  Environmental Conservation Areas seek to preserve broader ecological processes and functions.  These areas often encompass multiple resources also designated at the site‐specific scale.  Natural Areas and Natural Landmarks designations are intended to encompass and protect  Environmental Resources Element Page 1

  unique and distinctive natural features and landscapes in the county. The fundamental and  essential sustaining resources of air, soil, and water are also considered and addressed.     While this Element calls specific attention to the aforementioned designated environmental  resources (Environmental Resources), it also recognizes that these are not the only  environmental resources of significance and importance that should be considered in land use  decisions and cared for through management practices. With this in mind, Boulder County’s  overarching intention is to maintain the overall health and integrity of our rich and diverse  environment to the greatest extent possible as our knowledge and understanding of  environmental functions and interconnections evolves. The term “environmental resources” as  used in this Element consists of both the designated “Environmental Resources” and  undesignated environmental resources.    To provide some context for the goals and policies, a brief explanation of the environmental  resource designations and their importance to the ecosystems of Boulder County follows. For  the most part, these designations are those that already are utilized by reference in the Boulder  County Land Use Code. Designations added or amended in updates to this Element will also be  protected through administration of the Code and in conformance with applicable Federal and  State law. The criteria used to determine these designations are periodically reviewed and  updated resulting in updated lists of Species of Special Concern and updated maps of the  Environmental Resources Element. Descriptions of these designations follow.    Environmental Conservation Areas  Environmental Conservation Areas (ECAs) encompass the largest remaining relatively natural or  restorable forests, shrublands, grasslands, and agricultural landscapes in Boulder County. Even  with the current amount of relatively undeveloped public land in the county, and the  conservation and preservation efforts of public land managers on these lands, broad shifts in  animal and plant communities are occurring as a result of development, habitat degradation,  climate change, and the exclusion or disruption of natural processes. ECAs are a planning tool  developed by the County and its agency partners for analyzing land use and land management  decisions in the context of the cumulative effects of development, roads, trails and increased  human presence at a landscape‐scale on these large and complex ecosystems. This land use  decision‐making tool is used as a strategy for maintaining the wide‐ranging animal species,  native plant communities, and natural ecological processes that operate at this landscape scale.     ECAs are a framework for ecosystem management that identifies and designates valuable  ecological areas and delineates corridors of connectivity between them regardless of  ownership.  With this designation, land use and land management decisions within and  adjacent to ECAs and their connectors can be made within a framework that seeks to: protect  species that may be wide‐ranging, ecologically specialized or disturbed by human presence;  encourage the return of species lost from the county; prevent additional habitat fragmentation;  and limit increases in invasive non‐native species in these ecologically‐significant areas.  Such  planning and decision‐making processes may include resource management plans, the location  Environmental Resources Element Page 2

  and extent of new development, future land and easement purchases for open space purposes,  and the location of trails and other public facilities.    High Biodiversity Areas  High Biodiversity Areas (HBAs) are locales that have a concentration of rare environmental  resources. If managed well, they represent the greatest opportunities for preserving specific  aspects of Boulder County’s natural heritage. The boundaries of HBAs encompass those lands  that provide the habitat and ecological processes upon which the resources depend for their  continued existence. These areas have been identified and ranked ‐‐ by the CSU Colorado  Natural Heritage Program ‐‐ as having outstanding significance (B1), very high significance (B2),  or high significance (B3).    Natural Landmarks   Natural Landmarks are prominent landscape features that distinguish a specific locality in  Boulder County. They are important for the views they afford, their value as scenic vistas and  backdrops, and the intrinsic value they hold as wildlife or plant habitats, natural areas, park and  open space preserves, and open land areas. However, the single criterion for designation shall  be its visual and scenic prominence as a landscape feature. They provide a record of Boulder  County’s natural heritage.     State and County Natural Areas  State and County Natural Areas are physical or biological areas that are unique and important  to the natural heritage of the state and/or the county. Each area either retains or has  reestablished its natural character, although it need not be completely undisturbed. It typifies  native vegetation and associated biological and geological features and provides habitat for  rare or endangered animal or plant species or includes geologic or other natural features of  scientific or educational value. State Natural Areas are designated as such by the Colorado  Natural Areas Program.    Significant Natural Communities  Significant Natural Communities are areas that are recognized by the presence of a critical plant  association that is limited in its distribution and occurrence. These areas have multiple  important environmental resources that co‐occur and interact. These areas have species and  processes that are relatively undisturbed by human actions and currently exist in their natural  state. These areas are also referred to as Critical Plant Associations in the Boulder County Land  Use Regulations.    Critical Wildlife Habitats   Critical Wildlife Habitats are the unique habitats which have a crucial role in sustaining  populations of native wildlife and in perpetuating and encouraging a diversity of native species  in the county.        Environmental Resources Element Page 3

  Wetlands and Riparian Areas  Wetlands and Riparian Areas have unique and critical functions in the ecosystem. Wetlands are  generally described as lands transitional between terrestrial and aquatic systems where the  land is covered by shallow water or soils are saturated during the growing season. Wetlands  have high biodiversity, are relatively rare, provide unique wildlife habitat, filter water, and  buffer floods. Riparian Areas are a unique combination of terrestrial plant communities and  aquatic systems associated with flowing water that provide unique habitat and important  movement corridors for wildlife.     Rare Plant Areas   Rare Plant Areas are sites that are known to have a high likelihood of having occurrences of  Plant Species of Special Concern.     Species of Special Concern  Species of Special Concern include the flora and fauna in the county whose populations may be  threatened or endangered, locally rare, experiencing long‐term non‐cyclical population  declines, isolated or restricted to distinct local habitat types, or native species which have  ceased to exist within Boulder County.   To summarize, restoring, protecting and preserving our natural environment and all of its  interdependent components upon which all things depend have been core values and  objectives of Boulder County since the adoption of the first county‐wide comprehensive plan in  1978. Numerous initiatives, plans and programs have been diligently pursued and implemented  in this quest, and have benefited from the involvement of many stakeholders and interested  parties in both the public and private sectors. The Environmental Resources Element is both a  compass and a tool for use in sustaining and advancing these efforts.  Goals of the Environmental Resources Element     B.1 Boulder County shall conserve and preserve environmental resources including its unique  or distinctive natural features, biodiversity, and ecosystems through protection and restoration  in recognition of the irreplaceable character of such resources and their importance to the  quality of life in Boulder County.    B.2 Boulder County sustains and protects native species, natural ecosystems and the  biodiversity of the region by designating High Biodiversity Areas, Natural Areas, Natural  Landmarks, Significant Natural Communities, Critical Wildlife Habitats, Species of Special  Concern, Wetlands, Riparian Areas, and Rare Plant Areas. Other resources and designations  may be identified in the future. These designated areas and species lists also provide a point of  reference for continued monitoring of long‐term ecological change.  Environmental Resources Element Page 4

  B.3 Boulder County shall promote the viability and integrity of all naturally occurring  ecosystems and their native species populations by applying a variety of environmental  resources management strategies in a manner that is consistent with current ecological  principles and sustainable conservation practices.    B.4 Boulder County recognizes that climate change is having significant impacts on our  environmental resources. As the body of climate science knowledge grows and potential effects  are better understood, Boulder County shall incorporate the best scientific information into  planning and decision‐making to adapt to and offset those impacts.     B.5 Boulder County shall continue to protect air, water and soil resources and quality, as well as  restore resources in a degraded condition to enhance overall environmental health. Pollution of  air, water, and soil, and pollution caused by noise or light, shall be eliminated or minimized to  the greatest extent possible in order to prevent potential harm to life, health and property, and  to reduce incremental degradation of the environment.    B.6 Boulder County shall continue to protect prominent natural landmarks and other unique  scenic, visual and aesthetic resources in the county.    B.7 Boulder County shall conserve and preserve Environmental Conservation Areas (ECAs) in  order to perpetuate native species, biological communities, and ecological processes that  function over large geographic areas and require a high degree of connectivity to thrive.    B.8 Boulder County shall protect environmental resources both at the site‐specific scale and  landscape scale through a variety of means such as partnerships with private landowners, non‐ governmental organizations, and other governmental agencies; education and outreach;  advocacy at the state and federal level; and other programs consistent with the goals and  policies of the Comprehensive Plan.    Environmental Resource Policies    Introduction  The general policies below (ER 1.01 to ER 1.08) pertain to all environmental resources.  Additional policies follow the general policies that expand on and are unique and specific to Air,  Water, Soil and Noise (ER 2.01 to ER 2.03), Environmental Conservation Areas (3.01 to 3.05),  and Natural Areas and Natural Landmarks (ER 4.01 to ER 4.03).    General Policies for Environmental Resources  The following policies apply to all environmental resources in Boulder County    ER 1.01   Boulder County plans and attendant regulations shall be formulated to insure that land uses  avoid where possible and otherwise minimize the destruction or adverse modification of  Environmental Resources Element Page 5

  environmental resources. Land use proposals shall be evaluated on a case‐by‐case basis for  their potential impacts to environmental resources identified in the BCCP as well as those  resources that may be identified on the site and in the vicinity of the proposal during a county  development review process. The applicant may be required to complete other studies,  inventories, or reports that address the proposal’s potential impacts on environmental  resources and include recommendations for mitigation of those impacts.    ER 1.02 Boulder County shall continue to identify and designate environmental resources that  have significance to Boulder County.  Such designations, and attendant maps, will be based on  criteria that use science, collaboration with experts, and on‐the‐ground verification to the  extent practicable. Boulder County may periodically reevaluate such criteria and designations.  ER 1.03 Scenic vistas shall be preserved as much as possible in their natural state.  ER 1.04 Boulder County shall work with federal, state, municipal and other public or quasi‐ public entities that have a jurisdictional or property interest in unincorporated lands within or  surrounding any designated environmental resources to achieve their protection.   ER 1.05 Boulder County shall work in partnership with private land owners and non‐ governmental organizations to protect, conserve, and restore designated environmental  resources using a variety of tools.   ER 1.06 Boulder County shall use its open space program as one means of achieving its goals for  protecting environmental resources.   ER 1.07 Boulder County shall encourage all private landowners to seek assistance from  appropriate governmental and non‐governmental entities to protect Boulder County’s  environmental resources.   ER 1.08 Boulder County shall modify plans, policies and regulations as necessary to adapt to  climate change in order to reduce species and ecosystem vulnerability and other potential  adverse impacts on environmental resources. These measures will guide environmental  resource management implementation aimed at protecting biodiversity and ecological  resiliency.   Air, Soil, Water, Noise and Light Policies  In addition to the general policies above, the following policies also apply specifically to air, soil,  water, noise and light.    ER 2.01 Boulder County shall seek to protect overall public and environmental health by  enforcing regulations concerning air, soil, water, noise and light pollution at the local level in  accordance with applicable law.     Environmental Resources Element Page 6
