February 4, 2020 Kelly Smith City of Fort Collins Natural Areas Department 1745 Hoffman Mill Road Fort Collins, Colorado 80524 RE: Ecological Characterization Study for 3516 South Mason Street Dear Ms. Smith, Mr. David Eisenstein, on behalf of 3516 South Mason Street LLC, requested ERO Resources Corporation’s (ERO) assistance in providing an Ecological Characterization Study (ECS) for a property at 3516 South Mason Street in Fort Collins, Larimer County, Colorado (Figure 1). 3516 South Mason Street LLC intends to purchase the property and lease it to a marijuana business, which the City of Fort Collins (City) has deemed a change in use that requires the transaction to go through its development review process. Introduction Section 3.4.1 of the Fort Collins Land Use Code (LUC) requires an ECS for development sites that contain, or are located within 500 feet of, an area or feature identified as a natural habitat or feature on the City of Fort Collins Natural Habitats and Features Inventory Map, or that are discovered during site evaluations associated with the development review process. The Larimer County Canal No. 2 (canal), which has been identified as a natural feature in the City’s mapping, occurs along the eastern boundary of the property. A 50-foot buffer from the top of the canal bank was determined to be the primary area of focus in the ECS for the City’s use in potentially defining a natural habitat buffer zone on the property (study area). On December 12, 2019, Jenelle Kreutzer and Anna Wistrom with ERO visited the study area to review potential natural resources (2019 site visit). During this assessment, activities included a jurisdictional wetland delineation, identification of vegetation communities and potential federally listed threatened and endangered species habitat, potential wildlife use of or movement through the study area, prominent views from or across the study area, and general ecological functions provided by the study area and its features. Below is a summary of the resources found in the study area and recommendations or future actions necessary based on the current site conditions and regulations. Kelly Smith Page 2 City of Fort Collins February 4, 2020 p:\10800 projects\10882 - 3516 south mason street ecological characterization study\deliverables\final ecs 3516 s mason street.docx ERO Resources Corporation Study Area Location The study area is in Section 26, Township 7 North, Range 69 West of the 6th Principal Meridian in Larimer County, Colorado (Figure 1). The UTM coordinates for the approximate center of the study area are 493348mE, 4487602mN, Zone 13 North. The longitude/latitude of the study area is 105.078554W/40.539136°N. The elevation of the study area is approximately 5,030 feet above sea level. Photo points of the study area are shown on Figure 2, and the photo log is included in Attachment A. Study Area Description The study area consists primarily of a commercial building, asphalt parking lot, and a gravel pad (Figure 2; Photo 1). The canal occurs along the eastern property boundary and within a small portion of the study area. The banks of the canal are near vertical with a wood retaining wall and metal guardrail delineating the top of the bank along the canal. A narrow fringe of wetland vegetation consisting of Emory’s sedge (Carex emoryi), reed canarygrass (Phalaris arundinacea), and a few sandbar willow shrubs (Salix exigua) occurs along the banks of the canal in the study area (Photo 2). Canada thistle (Cirsium arvense), a List B noxious weed species, is dominant in the uplands along the canal banks, and two small resprouting Siberian elm (Ulmus pumila) trees occur along the bank of the canal in the study area. A small patch of sandbar willows with an understory of smooth brome (Bromus inermis), meadow fescue (Schedonorus pratensis), Canada thistle, curly dock (Rumex crispus), poison hemlock (Conium maculatm), and intermediate wheatgrass (Thinopyrum intermedium) occurs along the northern boundary of the property and just north of the gravel pad within the study area (Photo 3). A few songbird nests were observed in mature trees located outside of the study area and on the adjacent property to the north (Photo 4). Wetlands and Waters of the U.S. The Clean Water Act (CWA) protects the chemical, physical, and biological quality of waters of the U.S. The U.S. Army Corps of Engineers’ (Corps) Regulatory Program administers and enforces Section 404 of the CWA. Under Section 404, a Corps permit is required for the discharge of fill or dredged material into wetlands and other waters of the U.S. The Corps defines waters of the U.S. as “all navigable waters and their tributaries, all interstate waters and their tributaries, all wetlands adjacent to these waters, and all impoundments of these waters.” ERO conducted the wetland delineation following the methods for routine on-site wetland determinations in areas of less than 5 acres as described in the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual) (Environmental Laboratory 1987) and used methods in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0) (Corps 2010) to record data on vegetation, soils, and Kelly Smith Page 3 City of Fort Collins February 4, 2020 p:\10800 projects\10882 - 3516 south mason street ecological characterization study\deliverables\final ecs 3516 s mason street.docx ERO Resources Corporation hydrology on routine determination forms, which are included in Attachment B. The canal top of bank was also identified during this assessment. The boundaries of identified wetlands and other characteristics of potential waters of the U.S. were mapped using a Trimble Global Positioning System (GPS) unit. During the 2019 site visit, ERO mapped 0.002 acre of wetlands along the canal within the study area (Figure 2). The wetlands in the study area are dominated by reed canarygrass, which is a nonnative species, and lack species diversity and vegetation structure. The wetlands are assisting with bank stabilization, but overall, are low functioning. The area containing sandbar willows north of the gravel pad in the study area has an understory dominated by upland species and, therefore, does not have the vegetation indicators required to meet the Corps’ definition of a wetland. Should any work occur within the wetlands or below the ordinary high water mark of the canal, a Section 404 permit would likely be required from the Corps. If no work is planned in these areas, no further action is necessary. Threatened, Endangered, and Candidate Species During the 2019 site visit, ERO assessed the project area for potential habitat for threatened, endangered, and candidate species listed under the Endangered Species Act (ESA). Federally threatened and endangered species are protected under the ESA. Adverse effects on a federally listed species or its habitat require consultation with the U.S. Fish and Wildlife Service (Service) under Section 7 or 10 of the ESA. The Service lists several threatened and endangered species with potential habitat in Larimer County, or that would be potentially affected by projects in Larimer County (Table 1). Table 1. Federally threatened, endangered, and candidate species potentially found in Larimer County or potentially affected by projects in Larimer County.

Source: Service 2020. Habitat for black-footed ferret, Canada lynx, Mexican spotted owl, bonytail chub, Colorado pikeminnow, greenback cutthroat trout, razorback sucker, and North Park phacelia does not occur in the study area. The interior least tern, piping plover, whooping crane, pallid sturgeon, and western prairie fringed orchid are species that are affected by depletions to the Platte River system. Based on ERO’s knowledge of the types of activities likely to be implemented as part of purchasing the property, there would be no depletions to the South Platte River. Kelly Smith Page 5 City of Fort Collins February 4, 2020 p:\10800 projects\10882 - 3516 south mason street ecological characterization study\deliverables\final ecs 3516 s mason street.docx ERO Resources Corporation Because of the lack of habitat, no further action is necessary regarding federally threatened and endangered species. Migratory Birds Migratory birds, as well as their eggs and nests, are protected under the Migratory Bird Treaty Act. ERO did not observe any active or inactive migratory bird nests, including potential raptor nests, in the study area during the 2019 site visit. A few potential songbird nests were observed in the mature trees in the adjacent property to the north and outside of the study area. ERO is also not aware of any raptor nests in the vicinity of the study area. If active nests are identified within or near the study area, activities that would directly affect the nests should be restricted. Habitat-disturbing activities (e.g., tree removal, grading, scraping, and grubbing) should be conducted in the nonbreeding season to avoid disturbing active nests, or to avoid a “take” of the migratory bird nests within the project area. However, activities such as this are not likely to occur since no new site development is proposed on the property. Other Wildlife The study area is within the overall range of mule deer, white-tailed deer, and black bear (Natural Diversity Information Source 2016). However, because most of the study area lacks vegetation cover and is surrounded by dense commercial development, it does not provide wildlife habitat. Although the study area contains about 80 linear feet of the canal, upstream and downstream of the study area the canal is highly fragmented, with significant portions of the canal being piped underground. Therefore, the canal does not provide any significant wildlife habitat or serve as a movement corridor. Any wildlife using the study area have likely become adapted to human disturbance. Views The area surrounding the study area is fully developed, with commercial buildings and roads, with no significant natural area views. The mountains to the west are not easily seen due to topographic relief and development. The canal is easily seen from the study area; however, the canal is piped underground about 500 feet upstream and downstream of the study area. Conclusions and Recommendations As previously stated, 3516 South Mason Street LLC intends to purchase the existing property as is with no new development proposed. Section 3.4.1 of the LUC calls for buffers of various widths around natural habitats and special features. However, the study area currently provides little to no ecological function because about 90 percent of the area consists of buildings and impervious surfaces. Within the study area, the canal consists of nearly vertical banks with a narrow fringe of wetlands dominated by reed canarygrass along the toe of slope Kelly Smith Page 6 City of Fort Collins February 4, 2020 p:\10800 projects\10882 - 3516 south mason street ecological characterization study\deliverables\final ecs 3516 s mason street.docx ERO Resources Corporation and uplands containing Canada thistle. Because of the steep banks, isolated pockets of woody vegetation, and dominance of nonnative species, the portion of the canal in the study area has low-quality habitat and is likely only used occasionally by wildlife. Furthermore, there is no suitable habitat for federally threatened or endangered species or locally sensitive species in the study area. The canal and adjacent wetlands may be under the jurisdiction of the Corps; however, 3516 South Mason Street LLC is not proposing any activities along the canal that would trigger the need for a Section 404 permit. As part of purchasing the property, 3516 South Mason Street LLC is proposing to convert 0.03 acre of the existing 0.041-acre gravel pad into a native upland grassland (Figure 3) and to implement a noxious weed treatment plan long the canal. Because of the likelihood that the water running off from the adjacent parking lots would have high nutrients and salts and because of the proximity to the canal, ERO recommends using the City Natural Areas alkaline seed mix. A few native upland tree and shrub species would also be planted along the top of the bank of the canal. Converting the gravel area to a native upland would increase the ecological functions in the study area by improving water infiltration, reducing nutrient-rich runoff from entering the canal, and creating habitat for small wildlife and pollinators.

Schedonorus pratensis Although the study area contains small patches of sandbar willow and other riparian trees, the cover is too sparse and isolated to be considered Preble’s habitat. In addition, the closest known capture site of Preble’s is approximately 5.5 miles northwest of the project area (Shenk, T. 1998). One trapping survey has been completed approximately 0.25 mile north of the project area with no Preble’s captured (Colorado Urban Wild 1998). Because the study area does not contain any potential habitat for Preble’s, no further action is necessary. The study area is not conducive to the establishment of ULTO and does not fall within the Service’s guidelines for ULTO surveys (Service 1992). The study area does not meet the survey guidelines because it is in Larimer County and is not located on a perennial tributary to the South Platte River. Furthermore, the study area has been greatly modified by human activity and the wetlands along the canal area are dominated by reed canarygrass, which is not a species associated with ULTO habitat. anticipated
