Introduction This report presents the Ecological Characterization Study (ECS) for use by the Northern Integrated Supply Project (NISP or the Project) in the NISP Site Plan Advisory Review application to the City of Fort Collins. In accordance with Fort Collins Land Use Code requirements, the purpose of this ECS is to document the natural features, habitats, and wildlife within the portion of the NISP inside the boundaries of the City of Fort Collins (hereafter referred to as the “Project Area”; Figure 1). Furthermore, the ECS documents the Project’s extensive coordination efforts and commitments to avoid, minimize, mitigate, and enhance ecological resources that would be impacted by the Project within the City of Fort Collins. The NISP Water Activity Enterprise (WAE) is the permittee and the entity that will implement identified mitigation measures. The Northern Colorado Water Conservancy District (Northern Water), acting by and through the NISP WAE, has contracted Pinyon Environmental, Inc. (Pinyon), to provide environmental compliance services during the pre- construction phase of the Project. Existing conditions and impacts to wildlife species and habitats within the Project Area have been described in the NISP Final Environmental Impact Statement (FEIS) (U.S. Army Corps of Engineers [USACE], 2018). Furthermore, the NISP WAE has undergone an extensive planning process in coordination with Colorado Parks and Wildlife (CPW) and private stakeholders to avoid, minimize, and mitigate impacts to fish and wildlife and enhance wildlife habitat. These measures are outlined in the Project’s Fish and Wildlife Mitigation and Enhancement Plan (FWMEP) (Northern Water, 2017). The provisions of the FWMEP are enforceable through an Intergovernmental Agreement executed between the State and applicant. The FWMEP has been developed in coordination with CPW to address impacts to fish and wildlife through the development of detailed mitigation and enhancement measures. Sections of the FEIS and FWMEP applicable to Fort Collins Land Use Code Requirements are summarized in the report below. 1.1 Project Overview The purpose of the Project is to meet a portion of the NISP Participants’ (15 towns and water districts in Larimer, Weld, Morgan, and Boulder Counties) current and projected future water supply needs. The overall goal of the Project is to provide 40,000 acre-feet of new, annual water to the NISP Participants. The Project includes the following infrastructure within Fort Collins city limits: The Poudre River Intake diversion structure Portions of the Poudre River Intake Pipeline The scope of this ECS is limited to project components on lands within the Fort Collins city limits. Information on other project infrastructure is provided for context but is not within the scope of this review. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 2 2. Development Standards Section 3.4.1 of the Fort Collins Land Use Code applies if any portion of the development site is within 500 feet of an area identified as a natural habitat or feature on the City's Natural Habitats and Features Inventory Map, or if any portion of the development site contains natural habitats or features that have significant ecological value, and such natural habitats or features are discovered during site evaluation and/or reconnaissance associated with the development review process. Natural habitats and features considered to have significant ecological value, per Section 3.4.1 of the Land Use Code, are as follows: (1) Natural Communities or Habitats: (a) Aquatic (e.g., rivers, streams, lakes, ponds) (b) Wetland and wet meadow (c) Native grassland (d) Riparian forest (e) Urban plains forest (f) Riparian shrubland (g) Foothills shrubland (h) Foothills forest (2) Special Features: (a) Significant remnants of native plant communities (b) Potential habitats and known locations of rare, threatened or endangered species of plants (c) Potential habitats and known locations of rare, threatened or endangered species of wildlife (d) Raptor habitat features, including nest sites, communal roost sites and key concentration areas (e) Concentration areas for nesting and migratory shorebirds and waterfowl (f) Migratory songbird concentration areas (g) Key nesting areas for grassland birds (h) Fox and coyote dens (i) Mule deer winter concentration areas (j) Prairie dog colonies one (1) acre or greater in size (k) Concentration areas for rare, migrant or resident butterflies (l) Areas of high terrestrial or aquatic insect diversity (m) Areas of significant geological or paleontological interest (n) Irrigation ditches that serve as wildlife corridors Because there are aquatic, wetland, and riparian forest habitats within 500 feet of the Project Area, Section 3.4.1 of the Land Use Code applies to the portion of NISP within the City of Fort Collins city limits. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 3 3. Discussion of Fort Collins Land Use Code 3.4.1(D)(1) Ecological Characterization Study Information 3.1 Section a – Wildlife Use Information describing 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 is presented below. Descriptions of wildlife use in the NISP Project Area, including the Poudre River Intake, are provided in the FEIS, Sections 3.10.1, 3.10.3, and 3.10.5, and in Table 3-27 (USACE, 2018). Detailed descriptions of species expected to occur in the region where the Project Area is located, as well as scientific names, are provided in the 2008 Wildlife Report (ERO, 2008a) and the 2015 Wildlife Supplement (ERO, 2015a). Information provided in this section is adapted from those documents. Table 1 summarizes the common wildlife species and habitats likely to be found in the Project Area. Table 1.

Scientific names are in ERO (2008a). The Project Area includes a portion of the Cache la Poudre River (Poudre River) where the Poudre River Intake diversion structure would be installed. Wetlands and riparian woodlands along the river provide important habitat for many species of wildlife, such as small mammals, migratory birds, reptiles, and amphibians. There are also several ponds near the Project Area that provide habitat for aquatic species and waterfowl (Figure 1). Common year-round resident mammals in the riparian corridor along the Poudre River include eastern cottontail rabbit, fox squirrel, striped skunk, raccoon, red fox, coyote, plains pocket gopher, and deer mouse. Many of these species are generalists and can be found in different habitats, ranging from upland grassland to Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 5 cottonwood woodlands. Mule deer and white-tailed deer also are common in the Poudre River riparian corridor. The Poudre River riparian corridor is mapped as a white-tailed deer concentration area (Figure 3-32 in USACE, 2018); this concentration area overlaps the Project Area. The western portion of the Project Area is mapped as winter range for both mule deer and white-tailed deer (Figures 3-34 and 3-35 in USACE, 2018). Many neotropical migrant bird species use the riparian corridor for either foraging, nesting, or resting during the spring and summer breeding season (generally, April through August). Species commonly associated with upland and riparian shrublands include yellow warbler, song sparrow, blue grosbeak, lazuli bunting, and common yellowthroat. Breeding birds commonly found in mixed species and cottonwood woodlands include Bullock’s oriole, American goldfinch, yellow warbler, black-capped chickadee, black-headed grosbeak, and western wood-pewee. Cottonwood woodlands provide nesting sites for cavity nesting species such as house wren, Lewis’s woodpecker, downy woodpecker, and northern flicker, communally nesting species such as great blue heron, and raptors including red-tailed hawk, Swainson’s hawk, Cooper’s hawk, sharp-shinned hawk, and great- horned owl. Many other raptor species may take shelter or forage in the riparian corridor during winter or migration (generally, September through March). The many ponds along the riparian corridor (mostly created from past gravel mining) provide open water habitat for waterfowl including wood ducks, mallards, Canada geese, loons, grebes, cormorants, herons, ibises, rails, cranes, avocets, sandpipers, gulls, and terns. Habitats along pond margins provide breeding and foraging habitat for songbirds such as song sparrows, common yellowthroat, and both yellow-headed and red-winged blackbirds. The ponds also provide habitat for amphibians including western chorus frog, Woodhouse’s toad, plains spadefoot, and bullfrog, an introduced species. Reptiles include bullsnake, eastern yellow-bellied racer, western terrestrial garter snake, plains garter snake, prairie rattlesnake, snapping turtle, painted turtle, and ornate box turtle. Reptiles and amphibians are year-round residents, which are dormant during the winter and active throughout the spring and summer. 3.2 Section b - Wetlands Information on the boundary of wetlands in the area and a description of the ecological functions and characteristics provided by those wetlands is presented below. In April 2019, Pinyon conducted a field-based wetland delineation of the parcel where the Poudre River Intake will be located (Pinyon, 2019a). Other portions of the Project Area have had wetlands mapped on a desktop level with visual field confirmation where access was available (Pinyon, 2019b). This mapping was more conservative (over-estimated wetland boundaries) than a formal wetland delineation, as it relied upon visual estimation of the maximum extent of wetland boundaries using vegetation and hydrology cues without soil sampling. Wetland boundaries are shown in Figure 2. The FEIS includes an overview of wetland types along the conveyance systems (USACE, 2018). Mesic mixed woodlands and mesic native shrublands along with palustrine emergent (PEM), palustrine scrub-shrub (PSS), and palustrine forested (PFO) wetlands occur along creeks and streams. Many PEM wetlands, some of which are associated with ponds or lakes or receive supportive hydrology from agricultural runoff or from canal seepage, occur along the conveyance alignment. Surface flow from the Poudre River is the primary hydrologic support for wetlands near the river, and shallow groundwater supports wetlands in the floodplain and slightly away from the riverbanks. Wetland functions were assessed at six study sites near the Poudre River and functional index scores ranged from functioning to highly functioning (ERO, 2012; USACE, 2018). Key functions provided by wetlands near the river include wildlife habitat, flood attenuation, water storage, nutrient/toxicant removal, sediment retention, and food chain support (ERO, 2012). Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 6 All impacts to wetlands associated with the pipeline will be temporary, with wetland areas being restored to pre-project conditions. The construction of the Poudre River Intake Diversion Structure will not impact wetland areas. Wetland impacts for the overall project, including those within the City of Fort Collins, have been quantified and reported to the U.S. Army Corps of Engineers (USACE) as part of the Individual Section 404 Permit Application for NISP. A Wetland Mitigation Plan has been prepared and submitted to the USACE to document how wetland impacts will be avoided, minimized, and mitigated (Pinyon, 2020). 3.3 Section c - Views Prominent views from or across the site are discussed below. A visual resources study was completed for NISP in 2008 (ERO, 2008b) and is summarized in the FEIS (USACE, 2018). Within the City of Fort Collins, much of the conveyance system is proposed to be constructed in an urban area and along existing rights-of-way for roads and trails. As discussed in the FEIS, the scenic quality of urban areas along the proposed pipeline is low to moderate (USACE, 2018). Multiple artificial forms exist such as a variety of power transmission lines, fences, paved roads, paved trails, and buildings. Visual obstruction by the pipeline would be temporary as it would be installed underground and the trench would be backfilled and revegetated. Representative photographs of the Project Area are shown in Table 2. Table 2. Representative Photographs of the NISP Project Area within the City of Fort Collins.

Photograph sources: Pinyon 2019a, Pinyon, 2019b, Pinyon, 2019c 3.4 Section d – Native Vegetation Information on the pattern, species, and location of significant native trees and other native site vegetation is discussed below. The 2008 Vegetation Report (ERO 2008c) and the 2015 Vegetation and Wetland Resources Supplement (ERO 2015b) provide detailed descriptions of the vegetation resources evaluated in the NISP conveyance system study areas. Agricultural lands are the dominant vegetation cover type within the conveyance system study areas. Where the conveyance systems cross upland open space, vegetation is mostly upland mixed grasslands with an abundance of non-native species. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 10 The Project Area is in northeast Fort Collins. The pipeline would have an intake on the Poudre River near the intersection of Mulberry Street and Lemay Avenue, near the Mulberry Wastewater Treatment Plant. Riparian habitat dominated by sandbar willow with scattered plains cottonwood occurs near the intake location on the Poudre River. The proposed intake is in an area with little understory vegetation. Nearby uplands are characterized by a mix of Kentucky bluegrass and smooth brome. The Poudre River Trail is along the north side of the Poudre River (Pinyon, 2019b). ERO mapped riparian vegetation along the Poudre River corridor as shown in Figure 3 (ERO, 2018). “Riparian deciduous tree-cottonwood” was the most prevalent riparian vegetation cover type with about 1,410 acres in the area mapped around the Poudre River. “Riparian herbaceous cattails/sedges/rushes (permanent standing water)” had a high occurrence with about 419 acres of cover, and “riparian-herbaceous – sedges/rushes/mesic grasses (waterlogged soils or moist soils)” had 303 acres of cover. “Riparian shrub-willow” had 216 acres of cover. The remaining categories, “riparian herbaceous-general”, “riparian deciduous tree-general”, “riparian deciduous tree-willow”, “riparian deciduous tree-boxelder”, “riparian deciduous tree-Russian olive”, and “riparian shrub-general”, each had less than 100 acres of cover, as mapped along the Poudre River by ERO (2018). In the Project Area within city limits, “riparian deciduous tree – cottonwood” is the dominant riparian vegetation cover type. 3.5 Section e – Non-native Vegetation Information on 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 is discussed below. Riparian mapping along the Poudre River in 2012 included areas designated as “riparian deciduous tree-Russian olive” (ERO, 2012). Russian olive is a non-native riparian tree that contributes to shade, canopy, aesthetics, and cooling. No significant areas of Russian olive or other non-native trees were mapped in the Fort Collins portion of the Project Area. At several sites studied near the Poudre River for the FEIS, recruitment of green ash and narrowleaf cottonwood was observed on the upstream reaches of the Poudre River. Green ash is a non-native tree that is not common in the mature overstory of these sites. The common occurrence of young green ash trees at these sites indicates that the woody riparian vegetation at these sites is transitioning from cottonwood (narrowleaf or plains) riparian woodlands to woodlands dominated by cottonwood and green ash. Crack willow, green ash, Russian olive, and Siberian elm are infrequently scattered within the woodlands, although crack willow and Russian olive can occur more commonly in certain associations. Other infrequently occurring non-native woody species are American elm, apple, honey locust, northern catalpa, privet, salt cedar, and white mulberry (USACE, 2018). Much of the proposed conveyance would be in previously disturbed upland areas along existing road rights-of- way, trails, and utility corridors. These upland areas are dominated by smooth brome (ERO, 2012; Pinyon, 2019a), a non-native grass that provides ecological value by stabilizing soil. 3.6 Section f – Water Bodies Information on the top of bank, shoreline, and high water mark of any perennial stream or body of water on the site is discussed below. Boundaries of non-wetland waters are shown on Figure 2. In April 2019, Pinyon conducted a field-based delineation of the parcel where the Poudre River Intake will be located; this included mapping the ordinary high water mark (OHWM) of non-wetland waters (Pinyon, 2019a). Other portions of the conveyance system within the City of Fort Collins have had open waters mapped on a desktop level with visual field confirmation Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 11 where access was available (Pinyon, 2019b). Water bodies mapped in and near the Project Area include the Cache la Poudre River, Boxelder Creek, irrigation ditches, and ponds. Impacts to water bodies associated with the pipeline will be temporary, with stream and ditch crossings being restored to pre-project conditions. Impacts to open waters for the overall project, including those within the City of Fort Collins, have been quantified and reported to the USACE as part of the Individual Section 404 Permit Application for NISP. 3.7 Section g – Sensitive and Specially Valued Species Information on areas inhabited by or frequently utilized by Sensitive and Specially Valued Species is discussed below. Specially Valued Species evaluated in the FEIS included federally listed species, state listed species, state special concern species, state Tier 1 species, and Bureau of Land Management sensitive species (USACE, 2018). There are some Specially Valued Species that have potential habitat in the Project Area within Fort Collins city limits. These Specially Valued Species are discussed in Table 3, along with measures that Northern Water has committed to for avoidance and minimization of impacts. Table 3. Specially Valued Species with Potential Habitat in the NISP Project Area within the City of Fort Collins Common Name Scientific Name Discussion Mammals Black-tailed prairie dog Cynomys ludovicianus Open space and agricultural lands in the Project Area may provide suitable habitat for black-tailed prairie dogs. NISP will conduct surveys to map black-tailed prairie dog colonies within the Project Area prior to construction. If prairie dogs are identified within the proposed construction area, they will be removed prior to construction in accordance with Fort Collins Land Use Code and the project’s FWMEP (Northern Water, 2017). Relocation efforts will be coordinated with CPW as necessary. Hoary bat Lasiurus cinereus Hoary bats are migratory bats that may roost in riparian trees within the Project Area during the summer. The project will minimize potential impacts on this species by making minor alignment changes and limiting construction working space in areas where mature trees are present. Preble's meadow jumping mouse Zapus hudsonius preblei Preble’s meadow jumping mouse existing conditions, potential impacts, and mitigation measures are discussed in the FEIS (USACE, 2018) and Conceptual Mitigation Plan (Northern Water, 2018). There is no mapped occupied habitat or critical habitat for Preble’s meadow jumping mouse within the Project Area. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 12 Common Name Scientific Name Discussion Birds Bald eagle Haliaeetus leucocephalus Bald eagles may roost or nest in the riparian habitats in or near the Project Area. As discussed in the FEIS and shown on Figure 3-39 in the FEIS, there are no mapped bald eagle nest or roost sites within 0.5 mile of the Project Area (USACE, 2018). Per the FWMEP, Northern Water will construct the pipeline outside of bald eagle nesting and roosting periods, and/or conduct surveys for bald eagle nests and roosts prior to construction (Northern Water, 2017). If nests or roosts are discovered, Northern Water will coordinate with the U.S. Fish and Wildlife Service (USFWS) and CPW regarding appropriate avoidance measures. Black-necked stilt Himantopus mexicanus This wetland bird is noted in the FEIS as potentially occurring in the conveyance system area. The FWMEP discusses measures that will be used to avoid and minimize impacts to wetland and aquatic habitats (Northern Water, 2017). Impacts from the conveyances will be temporary, with easements adjusted in wetland areas to limit the size of disturbance. Mitigation of impacts to nesting birds per the Migratory Bird Treaty Act (MBTA) is also part of the FWMEP identified in Section 5.2.3.2. Burrowing owl Athene cunicularia Burrowing owls may be found in portions of the Project Area where there are black-tailed prairie dog colonies. Per the project’s FWMEP, prairie dog colonies would be surveyed for burrowing owls prior to any work that would disturb them between March 15 and October 31. Where burrowing owls are present, prairie dog removal would be scheduled to occur from November 1 to March 14. If active nests are found during pre-construction surveys, they would be left undisturbed and “no-work” zones would be established around the nests until nesting is complete (Northern Water, 2017). Golden eagle Aquila chrysaetos Golden eagles generally forage in open habitats and use steep cliffs for nesting. No suitable nesting habitat has been identified for golden eagles within or near the Project Area (USACE, 2018). To avoid and minimize effects on golden eagles, Northern Water will follow requirements of the Bald and Golden Eagle Protection Act and the MBTA during and following construction activities (Northern Water, 2017). Lazuli bunting Passerina amoena This species is noted in the FEIS as a common wildlife species occurring in wetlands and riparian woodlands (USACE, 2018). The FWMEP discusses measures that will be used to avoid and minimize impacts to wetland and riparian habitats (Northern Water, 2017). Impacts from the conveyances will be temporary, with easements adjusted in wetland areas to limit the size of disturbance. Mitigation of impacts to nesting birds per the MBTA is also part of the FWMEP identified in Section 5.2.3.2. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 13 Common Name Scientific Name Discussion Lewis's woodpecker Melanerpes lewis This species is noted in the FEIS as a common wildlife species occurring in wetlands and riparian woodlands (USACE, 2018). The FWMEP discusses measures that will be used to avoid and minimize impacts to wetland and riparian habitats (Northern Water, 2017). Impacts from the conveyances will be temporary, with easements adjusted in wetland areas to limit the size of disturbance. Mitigation of impacts to nesting birds per the MBTA is also part of the FWMEP identified in Section 5.2.3.2. White-faced ibis Plegadis chihi The FEIS identifies ibis as a common wildlife species that may use aquatic habitats in and near the Project Area (USACE, 2018). The FWMEP discusses measures that will be used to avoid and minimize impacts to wetland and aquatic habitats (Northern Water, 2017). Impacts from the conveyances will be temporary, with easements adjusted in wetland areas to limit the size of disturbance. Mitigation of impacts to nesting birds per the MBTA is also part of the FWMEP identified in Section 5.2.3.2. Fish Brassy minnow Hybognathus hankinsoni This species is noted in the FEIS as potentially occurring in the Poudre River. As noted in the FEIS, construction of the Poudre River Intake diversion structure could have minor adverse impacts on fish (USACE, 2018). These impacts would be minimized by designing the structure to reduce sedimentation and allow for fish passage. Iowa darter Etheostoma exile This species is noted in the FEIS as potentially occurring in the Poudre River. As noted in the FEIS, construction of the Poudre River Intake diversion structure could have minor adverse impacts on fish (USACE, 2018). These impacts would be minimized by designing the structure to reduce sedimentation and allow for fish passage. Orangespotted sunfish Lepomis humilis This species is noted in the FEIS as potentially occurring in the Poudre River. As noted in the FEIS, construction of the Poudre River Intake diversion structure could have minor adverse impacts on fish (USACE, 2018). These impacts would be minimized by designing the structure to reduce sedimentation and allow for fish passage. Plains topminnow Fundulus sciadicus This species is noted in the FEIS as potentially occurring in the Poudre River. As noted in the FEIS, construction of the Poudre River Intake diversion structure could have minor adverse impacts on fish (USACE, 2018). These impacts would be minimized by designing the structure to reduce sedimentation and allow for fish passage.

The FWMEP discusses measures that will be used to avoid and minimize impacts to wetland and aquatic habitats (Northern Water, 2017). Impacts from the conveyances will be temporary, with easements adjusted in wetland areas to limit the size of disturbance. Milksnake Lampropeltis triangulum The milksnake may be found in the open upland and agricultural habitats in the Project Area (USACE, 2018). Impacts to this species would be temporary and minimized by prompt backfilling and revegetation of the pipeline trench after installation. Ornate box turtle Terrapene ornata The ornate box turtle may be found in the open upland and agricultural habitats in the Project Area (USACE, 2018). Impacts to this species would be temporary and minimized by prompt backfilling and revegetation of the pipeline trench after installation.

Habitats along the Poudre River include cottonwood woodlands, mixed species woodlands, upland and riparian shrublands, upland and mesic grasslands, wetlands, and open water, often with emergent vegetation along the edges. Figure 3 shows riparian habitat that was mapped along the Poudre River for the FEIS (ERO, 2018). The diversity of habitats along the Poudre River riparian corridor is an important resource for wildlife. Many species use the riparian habitat for cover, resting, foraging, breeding, nesting, and roosting. Riparian corridors are especially important to wildlife in urban areas, such as the City of Fort Collins, where riparian vegetation provides a refuge from developed and landscaped areas. Streams and ponds adjacent to riparian habitat provide an important source of food in the form of emerged adult aquatic insects for bats, lizards, and insectivorous birds (USACE, 2018). Close to the Poudre River, a narrow band of riparian vegetation provides important habitat for wildlife. Areas with broader riparian and natural vegetation, such as at some of the Fort Collins Natural Areas (McMurry, Salyer, River’s Edge, Running Deer, and more), have higher species diversity and abundance, especially bird species. The greater structural diversity of woodlands dominated by cottonwood and other species create more habitat types that tend to have a greater number of species and higher abundance. Wetland and riparian habitat within the Project Area may provide habitat for two federally listed species, the Ute ladies’-tresses orchid (ULTO) and Preble’s meadow jumping mouse (PMJM). Per the FWMEP, Northern Water will survey all pipeline areas with suitable ULTO habitat (i.e., wetland areas) for at least two years before construction (Northern Water, 2017). If ULTO is found within the construction footprint, Northern Water will coordinate with the USFWS regarding appropriate avoidance and minimization measures. There is no mapped occupied or critical habitat for PMJM within the Project Area (USACE, 2018). Per the NISP Biological Assessment (ERO Resources Corporation and Bristlecone Environmental Consulting, 2020), the Poudre River Intake and Pipeline overlap potential PMJM habitat, but construction at these locations would have an insignificant and discountable effect on PMJM for the following reasons: This portion of the Poudre River near the Poudre River Intake is in an urban portion of Fort Collins, and riparian vegetation is restricted to a narrow fringe along the river. Numerous trapping surveys have been conducted along this stretch of the Poudre River with no captures. The nearest known capture site to the Poudre River Intake Pipeline study area is more than 7 miles to the northwest. The USFWS concurred that NISP study areas in the urban area of Fort Collins, including the Poudre River Intake, are not likely to be occupied by PMJM. 3.9 Section i – Wildlife Movement Corridors Wildlife movement corridors are discussed below. The Poudre River provides important wildlife habitat that functions as a refuge for many species, especially when surrounded by urban development. The Poudre River riparian corridor is used for nesting, foraging, resting, roosting, and as a stopover during migration for many avian species. A few species of concern, including the black necked stilt and Lewis’ woodpecker, may use the wetlands and riparian corridor for foraging or as a stopover during migration (USACE, 2018). Small and large mammals may also use riparian areas along the Poudre River and Boxelder Creek as movement corridors. CPW has not mapped any big game migration corridors through or near the Project Area (USACE, 2018). Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 16 3.10 Section j – Ecological Functions The general ecological functions provided by the site and its features are discussed below. Primary habitat types in the Project Area include wetlands, riparian shrub/forest, and upland grasslands. As discussed in ERO (2015b), wetlands provide a number of functions including wildlife habitat, flood attenuation, short- and long-term water storage, nutrient/toxicant removal, sediment retention, and shoreline/bank stabilization. Riparian vegetation provides important habitat and movement corridors for wildlife, as discussed in sections 3.8 and 3.9. Compared with surrounding upland areas, riparian habitat is more densely vegetated and therefore provides an important refuge, as well as nesting, perching, and foraging areas for wildlife. Trees in riparian areas also provide shade, cooling value, and bank stabilization. Grasses in upland areas stabilize soils that would otherwise be subject to erosion, and grasslands provide important habitat for native wildlife species such as prairie dogs, burrowing owls, and box turtles. Uplands also provide open hunting habitat for predators such as raptors and coyotes. 3.11 Section k - Timing Issues regarding the timing of development-related activities stemming from the ecological character of the area are discussed below. During the breeding season (i.e., April to July) that precedes commencement of construction, NISP will retain a qualified biologist to perform surveys for raptor nests; fox, coyote, and badger dens; and prairie dog colonies. Locations of these features will be mapped so that potential impacts can be assessed. This timing is proposed to make sure survey information is current and accurate for construction purposes. CPW-recommended timing restrictions and buffer zones will be applied to raptor nests to comply with the Bald and Golden Eagle Protection Act and MBTA. Fox, coyote, and badger dens will be avoided by a buffer of at least 50 feet, or, if not possible to maintain a 50-foot buffer, Northern Water will work with CPW and/or Fort Collins Natural Areas staff to implement other avoidance and minimization measures (e.g., exclusionary measures, timing restrictions). Prairie dog relocation will be coordinated with CPW and timed to avoid the burrowing owl season (March 15 to October 31), if nesting burrowing owls are identified. Where possible, vegetation clearing will occur outside of the migratory bird nesting period, prior to construction. The installation of deterrents to prevent nesting before April 1, and removal of these deterrents no more than 24 hours before initiation of construction, is an acceptable alternative to prohibiting construction activity during the breeding season. If it is not possible to time construction to occur outside the breeding season or preclude nesting with deterrents, surveys would be conducted prior to the initiation of construction activities to identify nests of migratory birds, raptors, and burrowing owls. If active nests are found during preconstruction surveys, they would be left undisturbed and “no-work” zones would be established around the nests until nesting is complete. Seasonal buffers and other timing restrictions that will be applied to protect wildlife are further detailed in the FWMEP (Northern Water, 2017). 3.12 Section l - Mitigation Measures needed to mitigate the projected adverse impacts of the development project on natural habitats and features are discussed below. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 17 Mitigation measures are described in the FWMEP and summarized in Table A1 within that document (Northern Water, 2017). Specific to the Poudre River Intake Pipeline Project Area, these measures include: Seasonal buffers as discussed in Section 3.11 Prompt backfilling and revegetation of the pipeline trench with a native seed mix (Appendix A) Reduction of temporary easement area and limiting encroachment by personnel and equipment in wetlands and riparian areas Designing and installing the Poudre River Intake structure to limit sedimentation and allow for fish passage Furthermore, the Fort Collins Land Use Code Section 3.4.1.(E) establishes performance standards for buffer zones around identified natural features. Buffer zones identified for the Project Area are shown on Figure 4. Table 4 discusses conformance with the buffer zone standards in the Land Use Code. Table 4. Conformance with Fort Collins Land Use Code Buffer Zone Performance Standards. Buffer Zone Performance Standard Discussion (a) The project shall be designed to preserve or enhance the ecological character or function and wildlife use of the natural habitat or feature and to minimize or adequately mitigate the foreseeable impacts of development. The Poudre River Intake Pipeline would be installed underground and most impacts would be temporary and short term. The pipeline trench would be backfilled and revegetated with a native seed mix (Appendix A). After construction is complete the pipeline would not impact the ecological character or function of the natural habitats in the Project Area. The Poudre River Intake diversion structure would be designed and installed to allow fish passage and limit sedimentation. The small footprint of this feature is not expected to negatively impact the functioning of the Poudre River or surrounding riparian area. (b) The project, including, by way of example and not by way of limitation, its fencing, pedestrian/bicycle paths and roadways, shall be designed to preserve or enhance the existence of wildlife movement corridors between natural habitats and features, both within and adjacent to the site. No fences, pathways, roadways, or other physical above-ground features are proposed that would degrade or limit wildlife movement corridors. (c) The project shall be designed to preserve existing trees and vegetation that contribute to the site's ecological, shade, canopy, aesthetic, habitat and cooling value. Notwithstanding the requirements of Section 3.2.1(F), all trees and vegetation within the Limits of Development must be preserved or, if necessary, mitigated based on the values established by the Ecological Characterization Study or the City Environmental Planner. Such mitigation, if necessary, shall include trees, shrubs, grasses, or any combination thereof, and must be planted within the buffer zone. Impacts would be minimized within treed areas by limiting construction working space and making minor alignment changes. Tree mitigation and revegetation measures are described in the Erosion Control/Landscape Restoration Plan Memorandum. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 18 Buffer Zone Performance Standard Discussion (d) The project shall be designed to protect from adverse impact species utilizing special habitat features such as key raptor habitat features, including nest sites, night roosts and key feeding areas as identified by CPW or the Fort Collins Natural Areas Department (NAD); key production areas, wintering areas and migratory feeding areas for waterfowl; heron rookeries; key use areas for wading birds and shorebirds; key use areas for migrant songbirds; key nesting areas for grassland birds; fox and coyote dens; mule deer winter concentration areas as identified by the CPW or NAD; prairie dog colonies one (1) acre or greater in size; key areas for rare, migrant or resident butterflies as identified by the NAD; areas of high terrestrial or aquatic insect diversity as identified by the NAD; remnant native prairie habitat; mixed foothill shrubland; foothill ponderosa pine forest; plains cottonwood riparian woodlands; and wetlands of any size. Buffers that have been identified for the Project Area per the Land Use Code Section 3.4.1 (E) “Buffer Zone Table” are shown on Figure 4. Due to the linear nature of the proposed infrastructure, it is not possible to avoid all identified buffers, but the alignment has been adjusted to avoid buffer encroachment where feasible. Furthermore, the width of the temporary easement would be reduced in certain areas (e.g., wetland crossings) to limit temporary impacts. As discussed in Section 3.11, seasonal timing restrictions would be applied to sensitive resource locations per the FWMEP. If possible, construction would be timed to occur outside of sensitive time periods for wildlife (e.g., migratory bird nesting season). If construction is planned to occur during the nesting season, surveys would be conducted to identify locations of sensitive resources so that appropriate buffers could be applied in accordance with CPW guidance. Construction impacts from the pipeline would also be temporary, with the restoration of preconstruction vegetation and habitat. (e) The project shall be designed so that the character of the proposed development in terms of use, density, traffic generation, quality of runoff water, noise, lighting and similar potential development impacts shall minimize the degradation of the ecological character or wildlife use of the affected natural habitats or features. The majority of project infrastructure would be located underground and have no impacts associated with noise, lighting, traffic, land use, density, or runoff after construction is complete. (f) The project shall be designed to integrate with and otherwise preserve existing site topography, including, but not limited to, such characteristics as steepness of slopes, existing drainage features, rock outcroppings, river and stream terraces, valley walls, ridgelines and scenic topographic features. Project infrastructure would restore existing conditions and have no permanent impact on slopes, drainage features, rock outcroppings, terraces, or valley walls. (g) The project shall be designed to enhance the natural ecological characteristics of the site. If existing landscaping within the buffer zone is determined by the decision maker to be incompatible with the purposes of the buffer zone, then the applicant shall undertake restoration and mitigation measures such as regrading and/or the replanting of native vegetation. The project would include backfilling the pipeline trench to match existing contours and revegetating disturbed areas with a native seed mix (Appendix A). Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 19 Buffer Zone Performance Standard Discussion (h) The project may be designed to provide appropriate human access to natural habitats and features and their associated buffer zones in order to serve recreation purposes, provided that such access is compatible with the ecological character or wildlife use of the natural habitat or feature. As a water intake and underground pipeline, the project features would neither impede nor enhance recreational access. (i) Fencing associated with the project shall be designed to be compatible with the ecological character and wildlife use of the natural habitat or feature. No fencing is proposed within buffer zones in the Project Area. Northern Integrated Supply Project Ecological Characterization Study Report City of Fort Collins Larimer County, Colorado Page 20 4. Conclusions This ECS Report has been prepared in accordance with the requirements of Section 3.4.1 of the Fort Collins Land Use Code. Data collected as part of the NISP National Environmental Policy Act (NEPA) process, culminating in the FEIS, have been used to characterize the natural habitats and features in the Project Area. Sensitive habitats identified in the Project Area include aquatic, wetland, and riparian areas associated with the Poudre River, Boxelder Creek, and their floodplains. Northern Water would avoid, minimize, and mitigate for impacts in accordance with the measures in the FWMEP (Northern Water, 2017), Conceptual Mitigation Plan (Northern Water, 2018), and as otherwise committed to in the FEIS and outlined in this ECS.
