(Terracon) was retained by Touchmark Development & Construction Co. (Client) to conduct an Ecological Characterization Study for the Proposed Retirement Community in Fort Collins, Colorado. This study was performed in accordance with Terracon Proposal P20247058 dated June 26, 2024 and the Consulting Agreement dated August 9, 2024. The City of Fort Collins Land Use Code Article 5.6.1 states, "If the development site contains, or is within five hundred (500) feet of, a natural habitat or feature, or if it is determined by the Director, upon information or from inspection, that the site likely includes areas with wildlife, plant life and/or other natural characteristics in need of protection, then the developer shall provide to the City an ecological characterization report prepared by a City approved professional qualified in the areas of ecology, wildlife biology or other relevant discipline." The Land Use Code Article also requires description of any measures needed to mitigate impacts on natural habitats and other ecological features. 1. 1 Site Location / Ecoregion The site is located at 4710 Cinquefoil Lane in Fort Collins, Larimer County, Colorado (Exhibit 1) and consists of approximately 18 acres of vacant land associated with Larimer County Parcel No. 8604000017. The site location is depicted on Exhibit 2 of Appendix A, which was reproduced from a portion of the United States Geological Survey (USGS) 7.5-minute series topographic map. The project site is located within Level III Ecoregion 25-High Plains and Level IV Ecoregion 251-Front Range Fans. Descriptions of each are highlighted below. High Plains (25) - Higher and drier than the Central Great Plains (27) to the east, and in contrast to the irregular, mostly grassland or grazing land of the Northwestern Great Plains (43) to the north, much of the High Plains comprises smooth to slightly irregular plains having a high percentage of cropland. Grama-buffalo grass is the potential natural vegetation in this region as compared to mostly wheatgrass-needlegrass to the north, Trans-Pecos shrub savanna to the south, and taller grasses to the east. The northern boundary of this ecological region is also the approximate northern limit of winter wheat and sorghum and the southern limit of spring wheat. Below is the Level IV Ecoregion of the High Plains within the project area: Front Range Fans (251): The Front Range Fans ecoregion flanks the northern Front Range of the Southern Rockies in Colorado. Streams tend to be cooler than in other High Plains (25) regions and contain many Front Range aquatic species. The soils of the region have more outwash gravels than regions farther east and occupy old terraces, benches, and alluvial fans. The soils are formed from materials weathered from arkosic sedimentary rock, gravelly alluvium, and redbed shales and sandstone. Some soils have a high shrink-swell potential. Environmental I Geotechnical I Materials 1 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 Land use is changing from mostly cropland and rangeland to more extensive urban development. Development has led to an increase in manmade lakes and gravel pits dotting the region. (Chapman, et al., 2006). 1.2 Existing Conditions At the time of the site reconnaissance, the project area consisted of vacant land with a storm water detention pond present on the east part of the site. The land cover consisted of non- native weed cover on most of the site and primarily native plant cover at the stormwater detention pond. 1.3 Proposed Project Terracon understands the anticipated future use of the site is development as a senior living community which will include a primary 60,000 square foot, 3-story building with an underground parking garage, a secondary 20,000 square foot, 2-story building with a potential underground parking garage, and 40 to 50 smaller dwellings at 2,000 to 3,000 square feet each. 2.0 REGULATORY SETTING 2. 1 Endangered Species Act (ESA) The United States Fish and Wildlife Service (USFWS) has the authority under the ESA to list and monitor the status of species whose populations are considered imperiled. USFWS regulations that implement the ESA are codified and regularly updated in 50 CFR Part 17. The federal process identifies potential candidates based on biological vulnerability. The vulnerability assessment considers several factors affecting a species within its range and is linked to the best scientific data available to the USFWS. Species listed as threatened or endangered by the USFWS are afforded full protection under the ESA, including the prohibition of indirect take such as the destruction of designated critical habitat. Section 7 of the ESA requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in Information, Planning, and Conservation System (IPaC), or from the local field office directly. Environmental I Geotechnical I Materials 2 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado November 6, 2024 1 Terracon Report No. 20247058 2.2 Bald and Golden Eagle Protection Act (BGEPA) Bald and golden eagles, having been delisted under the ESA, are still afforded federal protections under the BGEPA (16 U.S.C. 668-668c), enacted in 1940. Under the BGEPA it is unlawful to take, possess, sell, purchase, barter, offer to sell, possess, transport, export or import, bald or golden eagles, alive or dead, including any part (including feathers), nest (including inactive nests), or egg, unless allowed by permit. A "take" under the BGEPA is defined as to "pursue, shoot, shoot at, poison, wound, capture, trap, collect, molest or disturb." The term "disturb", as defined in a final rule published in the Federal Register on June 5, 2007 (Volume 72, page 31332) means to "agitate or bother a bald or golden eagle to a degree that causes, or is likely to cause, based on the scientific information available (1) injury to an eagle, (2) a decrease in its productivity, by substantially interfering with normal breeding, feeding, or sheltering behavior, or (3) nest abandonment, by substantially interfering with normal breeding, feeding, or sheltering behavior." 2.3 Migratory Bird Treaty Act (MBTA) ESA and State-listed avian species, as well as other migratory birds, are protected under the MBTA. The 1918 MBTA establishes a Federal prohibition "to pursue, hunt, capture, kill, collect, possess, buy, sell, trade, or transport any migratory bird, nest, young, feather, or egg, without a permit" issued in accordance with the policies and regulations of the MBTA. Take is defined as "to pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to pursue, hunt, shoot, wound, kill, trap, capture, or collect migratory birds". The MBTA does not prohibit the destruction of the bird nest alone (without birds or eggs) provided that no possession of the nest occurs during destruction. The USFWS is the lead agency determining permitting requirements for nest removal or destruction for birds protected under the MBTA. Under the current regulatory framework, there are no provisions for allowing the take of migratory birds that are unintentionally killed or injured (incidental take). The USFWS is actively undertaking rule making procedures to define and regulate incidental take and has issued a Director's Order (Order) to provide interim guidance for the regulation of incidental take. In the Order, the USFWS indicates that they would enforce incidental takes as a statutory take in accordance with case law presiding in the state where the incidental take occurs. Under the Order, the following types of conduct are not a priority for enforcement against incidental take: (1) A member of the general public conducting otherwise legal activities that incidentally take migratory birds; (2) A Federal agency conducting activities in accordance with a signed memorandum of understanding with the USFWS developed under Executive Order 13186 for the conservation of migratory birds; or (3) A public- or private-sector entity conducting activities in accordance with applicable beneficial practices for avoiding and minimizing incidental take. Environmental I Geotechnical I Materials 3 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 Activities in accordance with applicable beneficial practices for avoiding and minimizing incidental take can include conducting habitat removal outside of migratory bird nesting season or conducting nesting surveys of appropriate habitat to limit disturbance of nesting birds coinciding with habitat removal during nesting season. 2.4 Nongame, Endangered, or Threatened Species Conservation Act The Nongame, Endangered, or Threatened Species Conservation Act of 1984 is a Colorado state law making it unlawful for any person to take, possess, transport, export, process, sell or offer for sale, or ship and for any common or contract carrier to knowingly transport or receive for shipment any species or subspecies of wildlife appearing on the list of wildlife indigenous to Colorado determined to be endangered or threatened. 2.5 Waters of the US (WOTUS) Delineation Terracon reviewed the following resources to evaluate the potential presence of jurisdictional waters of the U.S., including wetlands, on the site. ■ Topographic Map The United States Geologic Survey (USGS) 7.5-Minute Topographic Map of the subject site (Fort Collins, CO), published 2022, was reviewed to identify drainages or other potential waters of the U.S. within the project site. Based on this map, there appears to be one (1) waterway running offsite along the east site boundary from the north to the south. No drainages or waterways appeared to be onsite. See Exhibit 2 for the topographic map. ■ National Wetland Inventory Map Terracon reviewed National Wetland Inventory (NWI) data for the project site to identify potential wetland areas. NWI data for the project site was published by the U.S. Department of the Interior's Fish and Wildlife Service and did not identify any wetland areas based on stereoscopic analysis of high-altitude aerial photographs. One riverine wetland was identified offsite and adjacent to the east site boundary and was verified during site reconnaissance to be completely outside of the site. See Exhibit 3 for the NWI Map. ■ USDA NRCS Soil Survey Terracon reviewed the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Soil Survey data for the site to identify occurrences of documented hydric soils on the site as Larimer-Stoneham complex, 3 to 10 percent slopes, Nunn clay loam, 0 to 1 percent slopes, and the Nunn clay loam, 1 to 3 percent slopes. The Larimer-Stoneham complex soils, Nunn clay loam soils (0 to 1 percent slopes), and Nunn clay loam soils (1 to 3 percent slopes) are all well-drained, have no frequency of flooding or ponding, and have no hydric conditions. The NRCS soil survey map for the project area is included as Exhibit 4. Environmental i Geotechnical I Materials 4 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 ■ FEMA Flood Insurance Rate Map Terracon reviewed Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Map Number 08069C0994F, effective December 16, 2006. According to the FIRM panel, the project site is mapped in Zone X which lies outside the 100-year floodplain. The FIRM for the project area is included as Exhibit 5. 2.6 City of Fort Collins Land Use Code Article 5 The City of Fort Collins Land Use Code Article 5.6.1 states, "If the development site contains, or is within five hundred (500) feet of, a natural habitat or feature, or if it is determined by the Director, upon information or from inspection, that the site likely includes areas with wildlife, plant life and/or other natural characteristics in need of protection, then the developer shall provide to the City an ecological characterization report prepared by a City approved professional qualified in the areas of ecology, wildlife biology or other relevant discipline. The ecological characterization study shall describe, without limitation, the following: (I) the wildlife use of the area showing the species of wildlife using the area, the times or seasons that the area is used by those species and the "value" (meaning feeding, watering, cover, nesting, roosting, perching) that the area provides for such wildlife species; (II) the boundary of wetlands in the area and a description of the ecological functions and characteristics provided by those wetlands; (III) any prominent views from or across the site; (IV) the pattern, species and location of any significant native trees and other native site vegetation; (V) the pattern, species and location of all non-native trees and vegetation that contribute to the site's ecological, shade, canopy, aesthetic and cooling value; (VI) the top of bank, shoreline and high water mark of any perennial stream or body of water on the site; (VII) areas inhabited by or frequently utilized by Sensitive and Specially Valued Species; (VIII) special habitat features; (IX) wildlife movement corridors; (X) the general ecological functions provided by the site and its features; (XI) any issues regarding the timing of development-related activities stemming from the ecological character of the area; and Environmental I Geotechnical I Materials 5 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 (XII) any measures needed to mitigate the projected adverse impacts of the development project on natural habitats and features." 3.0 METHODOLOGY To identify wetlands, federal, and state T&E species with potential to occur on the proposed project site, a desktop review of publicly and readily available information was conducted along with a field survey. Sources reviewed included the USFWS IPaC system, Colorado Parks and Wildlife (CPW) T&E Species Profile website, Colorado Natural Heritage Program (CNHP), Colorado's Conservation Data Explorer (CODEX) report, NWI maps, USDA NRCS Soil Survey maps, FEMA FIRM, USGS Quadrangle maps, and aerial imagery. Following the database review, a field survey of the project site was conducted to supplement and validate previously characterized habitat documented through the desktop review. On October 4, 2024, a pedestrian survey was performed across the entire site and observations of potentially suitable habitat and species occurrence were documented, as well as the presence or absence of wetlands. Site photographs, included in Appendix C, provide examples of the physical characteristics observed during the field survey. 4.0 RECORDS REVIEW 4. 1 IPac Report T&E species are listed on the USFWS Information, Planning, and Conservation System (IPaC). An Official Species List dated September 3, 2024 was generated by IPaC. The list of T&E species compiled by the USFWS on the IPaC for the study area in Larimer County, Colorado includes eight species that should be considered in an effects analysis (reference USFWS IPaC Resource List in Appendix B). Table 1 (below) includes the species listed by the USFWS which may occur within Weld County, Colorado, their federal status, habitat descriptions/species information, and their potential to occur within the study area. Species with potential to occur within the study area are denoted by red highlighted rows.

State regulations do not require habitat protection for state listed T&E species; therefore, state listed T&E species are typically only a development constraint if individual species are identified onsite. Impact determinations were not made for Species of State Special Concern (SC), as they are not a statutory category. Of the 16 unique species listed, five species are listed as threatened, eleven are listed as endangered. The habitat and potential presence of these species within the site are described in the Table 2 below. Species with potential to occur within the study area are denoted in highlighted red rows.

Four species were listed as "Potential Regulatory Species within Study Area." The report states no critical habitat for sensitive or species of concern were identified within one mile of the study area.

On their Texas wintering grounds, Whooping Cranes spend their time on estuarine marshes, shallow bays, and tidal flats, sometimes venturing to nearby farmland. Salt grass, saltwort, smooth cordgrass, glasswort, and sea oxeye dominate the marshes, with Gulf cordgrass on the margins. Farther inland in their range are sandy, gently rolling grasslands with live oak, red bay, and bluestem plants. Migrating birds feed in croplands and roost in shallow, freshwater wetlands (All About Birds). *SE= State Endangered, ST= State Threatened, LE = Federally Endangered,XN = Non-Essential Experimental Population 5.0 ECOLOGICAL CHARACTERIZATION RESULTS A field habitat survey was conducted October 4, 2024 by Terracon to identify potentially suitable habitat for state and/or federally protected, threatened and/or endangered species, and to address Fort Collins Land Use Code Article 5. During the field habitat survey, dominant plant communities and habitats were characterized and areas containing potentially suitable protected species habitat (as identified during the resource review) were verified. 5. 1 Wildlife Use During the site survey, a black-tailed prairie dog (Cynomys ludovicianus) colony was observed throughout much of the site, particularly the west portion. Two red-tailed hawks (Buteo jamaicensis) were observed feeding at the prairie dog colony and later one was perched on a white fir (Abies concolor) tree on the site. A cottontail rabbit (Sylvaticus sp.) and deer mouse (Peromyscus maniculatus) were visually observed, coyote (Canis latrans) scat was observed on-site, as well as the shed skins of a bullsnake (Pituophis catenifer) and a garter snake (Thamnophis sp.). Several species of birds were observed during the site survey, including mourning doves (Zenaida macroura), Say's phoebes (Sayornis saya), and blue jays (Cyanocitta cristata) observed perching in the ornamental trees on the west part of the site, house finches (Haemorhous mexicanus) and American goldfinches (Spinus tristis) feeding on the common sunflower (Helianthus annuus) seeds at the stormwater detention pond, and western meadowlarks (Sturnella neglecta) using most of the site. An inactive bird nest was observed in one of the trees at the west edge of the site. In addition to the animal species observed using the site for feeding, cover, and nesting during the site survey, the site is likely utilized by other wildlife as well. These would include other species of migratory tree- and ground-nesting birds during the avian nesting season, and Environmental I Geotechnical I Materials 11 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 meso-predators (i.e. skunks, foxes, and raccoons) utilizing the area year-round for food and cover. 5.2 Wetlands Terracon's review of the NWI did not identify wetland features on the site. The topography of the site was primarily flat, other than the stormwater detention pond (SDP) on the east portion of the site. A stormwater sewer outlet was located at the north end of the SDP and a storm outfall structure was located at the south end of the SDP. Fossil Creek Reservoir Inlet is mapped offsite as a riverine feature flowing north to south along the east site boundary but was observed to have no connections to the site. Terracon performed a wetland delineation to confirm the presence or absence of wetlands on the site. Six data points were collected across all observed vegetative communities and in the three soil types mapped on the NRCS Soil Survey map. Wetland delineation forms are shown in Appendix C. No hydrophytic vegetation, hydric soils, or hydrology indicators were observed, suggesting that no wetland features exist on the site. As a result, no additional action is necessary. 5.3 Prominent Views The Front Range foothills are the most prominent visual feature when looking west from the site. Much of that view is obstructed by Banner Fort Collins Medical Center. To the north and northeast is a view looking down upon Arapahoe Bend Natural Area, which is an expanse of ponds and lakes, riparian forests, and open fields. A cluster of gravel pit ponds followed by Interstate 25 make up the view to the southeast from the site. Apartment buildings are the most prominent features when looking east (The Wyatt Apartments) and south (Morningside). There are no known visually sensitive areas (i.e. designated wilderness areas, parks, recreation areas, wild/scenic rivers, etc.) near the site. Development of the site will interfere to a degree with the westward view of the east adjacent Wyatt Apartments, but overall visual impacts will be minimal if the site is developed. 5.4 Native Tress and Vegetation The only native plant community observed at the site was on the slopes of the stormwater detention pond located at the east portion of the site. It was dominated by blue grama (Bouteloua gracilis), sideoats grama (Bouteloua curtipendula), and green needlegrass (Nassella viridula) with some non-native smooth brome (Bromus inermis) prevalent as well. A mixed native and non-native plant community occurred at the north portion of the stormwater detention pond. It was dominated by smooth brome, green needlegrass, switchgrass (Panicum vigatum), witchgrass (Panicum capillare), common sunflower (Helianthus annuus), tumbleweed (Salsola tragus), common evening-primrose (Oenothera biennis), and slender leafy spurge (Euphorbia virgata). Small plains cottonwoods (Populus deltoides) were starting to grow in this area well. Environmental I Geotechnical I Materials 12 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 5.5 Non-native Trees and Vegetation Upland areas on the project site were covered primarily by non-native prostrate pigweed (Amaranthus albus) and to a lesser degree smooth brome (Bromus inermis). These two communities had very little plant diversity consisting largely of only prostrate pigweed or smooth brome. Prairie dogs appeared to prefer the smooth brome-dominated community. Three non-native trees were located on the west edge of the site next to where a house existed in the past. The observed trees were Norway maple (Acer platanoides), white ash (Fraxinus americana), and white fir (Abies concolor). An inactive bird nest was present in the Norway maple and a few different species of birds were observed perching in all three of the trees during the site survey. The observed trees could serve as potential nesting sites for migratory birds and other animals. 5.6 Perennial Streams and Water Bodies No perennial streams or bodies of water occur on the site. However, Fossil Creek Reservoir Inlet does run north to south near the east site boundary. 5.7 Sensitive or Specially Valued Species After a review of the USFWS IPaC report, CNHP and CPW CODEX report, and the CPW list of state threatened and endangered species, followed by a site survey, Terracon identified one sensitive species, burrowing owl (Athene cunicularia), with the potential to occur in the project area. Burrowing owls are typically associated with prairie dog colonies because they use abandoned prairie dog burrows for nesting. The presence of a prairie dog colony on the site increases the probability of burrowing owl presence. 5.8 Special Habitat Features A special habitat feature associated with the site includes the presence of a prairie dog colony, which serves as potential habitat for state-listed threatened burrowing owls. 5.9 Wildlife Movement Corridors The project site is unlikely to serve as a corridor facilitating the movement of wildlife between areas of favorable habitat. The east adjacent Fossil Creek Reservoir Inlet likely serves as an important corridor for wildlife movement between wetlands and other open spaces near Fossil Creek to areas of favorable habitat near the Cache la Poudre River. Development of the site should not have any significant impacts on wildlife movement along Fossil Creek Reservoir Inlet. 5. 10 General Ecological Function The ecological function of the site is limited by the fragmented nature typical of a suburban environment and overall low-quality of the non-native vegetative cover. However, the presence of a prairie dog colony and a few trees provides cover and food for a web of other Environmental I Geotechnical I Materials 13 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 wildlife, such as those mentioned in section 5.1, and others that may not have been observed during the site survey. The site probably also serves as an additional foraging ground for wildlife traveling along the east adjacent Fossil Creek Reservoir Inlet corridor. 5. 11 Issues with Timing of Development Activities Burrowing owl surveys should be conducted prior to prairie dog control or construction-related activities if they occur within the burrowing owl breeding season (March 15th through October 31st). Surveys for ground- and tree-nesting birds should be performed prior to vegetation clearing or other construction-related activities if they are to occur during the migratory bird nesting season (April 1st through August 31st). See section 5.12 for more detail. 5. 12 Natural Habitat or Features Requiring Mitigation If prairie dog relocation, eradication, or burrow destruction, and/or ground clearing operations or other surface disturbances are to occur during the burrowing owl nesting season (March 15th through October 31st), a survey prior to construction to confirm the presence or probable absence of burrowing owl is recommended. This survey would occur prior to construction and be conducted weekly over the course of three weeks. Because occupancy status can change for each breeding season, surveys should be performed during each new breeding season. If an active burrowing owl burrow is identified, CPW recommends a 1/4-mile (1,320-foot) 'no surface disturbance' buffer is established around the nest from March 15th through October 31st or until it is confirmed owls have vacated the nest. If construction activities and ground disturbances are conducted outside the nesting season, there will be no potential for a take. Additionally, under current guidance covering incidental take under the MBTA, legal activities resulting in an incidental take while conducting activities in accordance with applicable beneficial practices for avoiding and minimizing incidental take would not be priority enforceable activities. In order to avoid incidental take enforcement actions, it is recommended that the clearing of habitat suitable for migratory birds (ground vegetation, trees, cattails, etc.) be conducted outside of nesting season. Additionally, when habitat disturbance is conducted during nesting season, a nest survey should be conducted between April 1st and August 31st, at least seven days prior to the beginning of clearing, to identify migratory birds and active nests to avoid during clearing activities. If construction activities and ground disturbances are conducted outside the nesting season, there will be no potential for a take under MBTA. 6.0 CONCLUSION AND RECOMMENDATIONS Terracon performed an Ecological Characterization Study to determine the impacts of developing the project site with a senior living community. The study was conducted by reviewing several desktop resources and performing an on-site field survey to collect data and photographs and record observations. One state-listed sensitive species, burrowing owl, was observed to have potential to occur on the site. The development of the site will result in Environmental � Geotechnical I Materials 14 Ecological Characterization Studyr�•C' �r r�� Proposed Retirement Community I Fort Collins, Colorado is November 6, 2024 1 Terracon Report No. 20247058 a low to moderate loss of ecological value to the area due to the low-quality non-native vegetative community covering most of the site. The ecological value is increased by the presence of the prairie dog colony that provides cover and foraging opportunities for a myriad of other wildlife species in the area. Following survey protocols for burrowing owls and migratory birds described in section 5.12 will lessen the impact on state-listed burrowing owls (if present) and other birds covered under the MBTA, and keep the client in compliance with federal, state, and local regulations discussed throughout this Ecological Characterization Study. 7.0 REFERENCES Chapman, S.S., Griffith, G.E., Omernik, J.M., Price, A.B., Freeouf, J., and Schrupp, D.L., 2006 Ecoregions of Colorado (color poster with map, descriptive text, summary tables, and photographs): Reston, Virginia, U.S. Geological Survey (map scale 1:1,200,000).

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the IPaC website at regular intervals during project planning and implementation for updates to species lists and information.An updated list may be requested through IPaC by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act(42 U.S.C. 4332(2) Project code: 2024-0138514 09/03/2024 14:57:54 UTC (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402.In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: https://www.fws.gov/sites/default/files/documents/ endangered-species-consultation-handbook.pdf Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act(ESA), there are additional responsibilities under the Migratory Bird Treaty Act(MBTA) and the Bald and Golden Eagle Protection Act(BGEPA) to protect native birds from project-related impacts.Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)).For more information regarding these Acts, see Migratory Bird Permit I What We Do I U.S. Fish &Wildlife Service (fws.gov). The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures, see https://www.fws.gov/library/collections/threats-birds. In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/partner/council-conservation- migratory-birds. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act.

This tool queries multiple conservation datasets and includes a synthesis of Colorado Natural Heritage Program (CNHP) and Colorado Parks and Wildlife (CPW) data for sensitive animal and plant species and natural communities. Care should be taken in interpreting these data. Please note that the absence of data for a particular area, species, or habitat does not necessarily mean that these natural heritage resources do not occur on or adjacent to the project site, rather that our files do not currently contain information to document their presence. CODEX information should not replace field studies necessary for more localized planning efforts, especially if impacts to wildlife habitat are possible. Although every attempt is made to provide the most current and precise information possible, please be aware that some of our sources provide a higher level of accuracy than others, and some interpretation may be required. CODEX data is constantly updated and revised. Please contact CNHP, CPW and our partners for assistance with interpretation of this report or to obtain more information. Disclaimer: 1. This is a preliminary environmental screening tool. It is not a substitute for the potential knowledge gained by having a biologist conduct a field survey of the project area. This review does not constitute environmental consultation (including federal consultation under the Endangered Species Act), land use permitting, or the review of site-specific projects by CNHP and CPW and our partners. 2. This Project Report is based on the project study area that was entered. The report must be updated if the project study area, location, or the type of project changes. 3. The Conservation Data Explorer (CODEX) data is constantly changing and being updated and is not intended to be the final word on the potential distribution of special status species. Colorado is large and diverse with plants, animals, and environmental conditions that are ever changing. Consequently, many areas may contain species that biologists do not know about or species previously noted in a particular area may no longer occur there. CODEX data contains information about species occurrences that have actually been reported to CNHP, CPW and our partners. Not all of Colorado has been surveyed for special status species, and surveys that have been conducted have varied greatly in scope and intensity. Such surveys may reveal previously undocumented population of species of special concern.

Project Report Appendix Please visit the CNHP website for a more extensive collection of definitions for CODEX reports in addition to what is provided here below. About CNHP Data One of CNHP's core research activities is managing a statewide database that details the locations of rare and imperiled species and natural plant communities in Colorado.We gather data from CNHP surveys and monitoring projects,as well as from partners and other trusted sources like herbariums.All of our data are compiled and managed in the Biodiversity Information Management System(Biotics), a web-enabled database platform hosted by NatureServe.The species and natural plant communities we track are assigned global and state imperilment ranks based on rarity,threats, and trends,and their locations are mapped as element occurrences. Element occurrences include spatial data as well as details on condition,size,and landscape context.This information allows us to track both overall distribution and site-specific details describing how well elements are thriving at each location.We use element occurrences to delineate Potential Conservation Areas that represent the primary area needed to support the element occurrences, and often include additional suitable habitat or buffers from disturbance. Please visit the CNHP website for more definitions and details related to CNHP data in CODEX. CODEX Report Definitions CNHP Biodiversity Rank—The significance of a potential conservation Managed Areas Name—Name of the managed area. area in terms of its biological diversity ranging from B1 (Outstanding Biodiversity significance meaning protection of this potential conservation Manager—The general land Manager. area can prevent a species from going extinct)to B5(General interest or open space for more globally secure species).
