As a part of our analysis, we looked at the existing conditions of the East Study Area to evaluate its suitability for use as a habitat mitigation site. As discussed in our March 2020 Wetland Delineation Report, there have been a number of hydrologic changes at the site which should be considered in developing an appropriate mitigation plan. Given the existing plant communities, we recommend that you focus on enhancing the area with additional trees and shrubs, however we have also provided some recommendations for herbaceous wetland plants, as discussed below. The following sections provide recommendations for two habitat zones, based on soil moisture requirements. The recommended plants are all desirable native species which occur in and around Fort Collins. As we have discussed, additional field observations of the site hydrology would be helpful for developing a more detailed restoration plan. This information is being provided to facilitate your discussion and restoration planning with the City of Fort Collins. Please call if you have questions.

It should be noted that the existing plant community is dominated by the aggressive, introduced species reed canarygrass (Phalaris arundinacea), which will compete with the native species. It may be difficult to shift the plant species composition without eradicating the reed canarygrass, unless the site becomes much wetter.

However, as noted above, temporary irrigation will be required during the first few growing seasons, and perhaps longer - depending on the site hydrology. This transitional area currently supports several Russian olive (Eleagnus angustifolia) trees, a state-listed noxious weed. Removal of these invasive species and establishing native trees and shrubs in their place would be a significant enhancement which could be used for mitigation.

When the apartments are constructed, an abandoned segment of the North Louden Ditch would be impacted. The City of Fort Collins is requiring mitigation for these impacts and the loss of trees along the ditch. A potential mitigation site has been identified by the City on a 4.77-acre parcel located just east of the proposed development at the southwest corner of Skyway Drive and College Avenue. To aid in project planning, wetlands were delineated for the potential mitigation site, herein known as the East Study Area (4.77 acres), as well as a small parcel immediately west of the proposed development, the West Study Area (1.58 acres) (Figures 1 & 2). These parcels and the proposed Mars Landing apartments are located in Section 11 of Township 6 North and Range 69 West in Larimer County, Colorado. For the purposes of mitigation planning, two boundaries were identified during the wetland delineation. The limit of wetland vegetation, or “City of Fort Collins Wetlands”, was mapped in addition to the limit of wetlands under the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual, as illustrated by Figure 3. This report describes the wetlands identified in the East and West Study Areas in terms of their vegetation, soil, and hydrology; provides site photos and a Wetland Map; and includes an analysis of the jurisdictional status and an evaluation of the suitability of the East Study Area for use as a habitat mitigation site. Please note, all Figures are included in Section 7.0; Tables are in Section 8.0; selected photos are included within the text in Section 2.0, while numbered site photos are in Section 9.0. Appendix A contains copies of the field data forms completed during the wetland delineation in January 2020. 2.0 ENVIRONMENTAL SETTING 2.1 East Study Area Panoramic view of the East Study Area taken from the southwest corner of Skyway Drive and College Avenue. The site slopes and drains to a topographic depression on the west side of College Avenue. 2 The East Study Area is bounded by Skyway Drive to the north, by College Avenue to the east, by a storage facility to the west, and by undeveloped agricultural lands to the south. The site has a gently sloping topography that drains to a depression on the west side of College Avenue. A culvert is located at the base of the depression and presumably carries water to the east below College Avenue. However, the inlet is clogged with sediment and there is a Siberian elm tree (Ulmus pumila) growing between the pipe and flared end section. The conditions observed during the wetland delineation suggest this culvert seldom flows. This topographic depression is down gradient of the North Louden Ditch and historical aerial photography suggests that irrigation tailwater collected in this area. However, as land uses have changed the site has experienced hydrologic changes. This area is no longer flood irrigated and the North Louden Ditch has been piped and no longer provides subirrigation or surface water to the depression in the East Study Area. The stormwater drainage in the vicinity of the East Parcel has also changed due to recent construction (Figure 3). The storage facility now occupies the once-irrigated farmland between the location of the proposed Mars Landing apartments and the East Study Area. A recently constructed stormwater detention pond is located just south of the storage facility which spills into the depression in the East Study Area. Likewise, there are two new culverts that convey stormwater runoff into the north side of the depression. These hydrologic changes are an important consideration for the evaluating the potential mitigation site and defining appropriate restoration goals, as discussed below in Section 6.0. Partially clogged culvert outfall below College Avenue in the East Study Area. 1999 Google Earth Aerial 2019 Google Earth Aerial 3 Stormwater released from the culverts and seasonal high groundwater support wetland development on the lower side slopes and bottom of the topographic depression, as illustrated by Figure 3. Wetland A is discussed in greater detail below in Section 4.1. 2.2 West Study Area The ±1.58-acre West Study Area is located along the western side of the proposed Mars Landing apartments. This study area is bounded by Gateway Center Drive to the west, by Skyway Drive to the north, and undeveloped agricultural lands to the south. The northern portion of the West Study Area is crossed by the abandoned segment of the North Louden Ditch, where an old diversion structure directed flows into a storage pond that is just south of Skyway Drive, inside a fenced enclosure (Figure 3). During field reconnaissance, it appeared that water was no longer being diverted into the pond and it was empty, but there was a sparse cover of wetland vegetation on the pond bottom, as discussed below in Section 4.2. A small, partially buried culvert was located near the southern end of the pond at Gateway Center Drive. This culvert could intermittently convey a small volume of stormwater runoff into the pond. South of the pond, the West Study Area has been seeded along the corridor where the North Louden Ditch was piped and buried. The irrigation storage pond was historically filled by the North Louden Ditch but does not show evidence of recent use. Seeded area along the North Louden Ditch pipeline corridor. 4 Elevations of the project site range from a high of approximately 5,052 feet in the field at the southwest corner of the West Study Area, to a low of approximately 4,998 feet in the topographic depression in the East Study Area. 3.0 DELINEATION METHODS Wetlands were delineated by Heather Houston and Kristin Schroder of Birch Ecology, LLC and David Buscher, a Certified Professional Soil Scientist with Buscher Soil & Environmental, on January 29, 2020. The delineation was conducted in accordance with the U.S. Army Corps of Engineers Wetland Delineation Manual (1987) and the Great Plains Regional Supplement (2010). In general, wetland boundaries were delineated and flagged based upon the prevalence of hydrophytic vegetation, hydric soils, and indicators of a wetland hydrology. Field forms for the 7 test pits with vegetation, soil, and hydrology data are included in Appendix A. The limit of hydrophytic vegetation was also mapped for Wetland A in the East Study Area, in accordance with City of Fort Collins regulations. In general, plant species names follow Weber and Whitmann (1992) with updates from Ackerfield (2015). The wetland status of plants follows the 2016 National List for the Great Plains Region (Lichvar et al., 2016). Classification of wetlands follows Cowardin et al. (1979). Wetland flagging was surveyed by Galloway & Company, Inc. of Johnstown, Colorado. 4.0 WETLANDS The Wetland Map (Figure 3) illustrates the boundaries of the “City of Fort Collins Wetlands” (limits of hydrophytic vegetation) and the “Corps of Engineers Wetlands.” These wetland areas are summarized in Table 1 and are discussed below. 4.1 East Study Area – Wetland A 4.1.1 Location Wetland A occupies the gently sloping sides and bottom of the topographic depression in the East Study Area (Photos 1-4). Based on the Corps’ standards, it measures approximately 16,870 ft2 (0.39 acre). If areas of hydrophytic vegetation are included which lack hydric soil and/or indicators of a wetland hydrology, in accordance with the City of Fort Collins, Wetland A measures 22,264 ft2 (0.51 acre). 4.1.2 Classification Under the Cowardin Classification System for Wetlands and Deepwater Habitats (Cowardin et al., 1979), Wetland A is in the Palustrine System, Emergent Persistent Wetland Class. 4.1.3 Vegetation Wetland A is dominated by reed canarygrass (Phalaris arundinacea), an introduced agricultural species that is common in irrigated areas, with the noxious weed quackgrass (Elytrigia repens), smooth brome (Bromus inermis), and small areas of Baltic rush (Juncus arcticus ssp. ater) at the periphery (Photos 2 & 3). In addition, a low cover of Nebraska sedge (Carex nebrascensis) occurs on the turf reinforcement matting below the northern stormwater culvert outfall, which may have been planted or seeded. The native threesquare bulrush (Scirpus pungens) is also sparsely present in the wetter areas near the 5 bottom of the depression, in addition to foxtail barley (Hordeum jubatum), alkali muhly (Muhlenbergia asperifolia), and saltgrass (Distichlis spicata). The uplands that surround Wetland A have been heavily grazed by prairie dogs and there is low vegetation cover. Smooth brome is the dominant grass, with some patches of crested wheatgrass (Agropyron cristatum) and quackgrass. Weedy forbs present in this area include flixweed (Descurainia sophia), prickly lettuce (Lactuca serriola), curly dock (Rumex crispus), and the noxious weed Canada thistle (Cirsium arvense), with a lower cover of the natives showy milkweed (Asclepias speciosa) and common sunflower (Helianthus annuus). A stand of large, mature plains cottonwood trees (Populus deltoides) is located in the uplands northwest of Wetland A (Photo 5). Several large Russian olive trees (Elaeagnus angustifolia), a Colorado state-listed noxious weed, also occur in the adjacent uplands (Photos 2 & 3). Table 2 lists the vascular plant species identified on the project site during the wetland delineation in January 2020. 4.1.4 Hydrology The East Study Area has an agricultural land use history and it is located downgradient of the now abandoned (and piped) segment of the North Louden Ditch. In the past, it appears to have received irrigation tailwater runoff but that is no longer the case. There appears to be a shallow groundwater table in this area, which also supports wetland development. The hydrology of Wetland A has changed due to the recent land use changes – the removal of irrigation water and the addition of new storwmwater culverts that drain into the depression. The extent of the Corps-defined wetlands and the extent of hydrophytic vegetation could change over the next several years due to these hydrologic changes. Today, stormwater runoff contributes to wetland development and Wetland A may also be supported by a seasonally high groundwater table. 4.1.5 Soils Soil within the East Study Area was disturbed within the previous few years during construction of the self-storage facility and installation of the stormwater drainage improvements, as noted on the field data forms in Appendix A. The NRCS soil types mapped within the study area are illustrated by Figure 4. The East Study Area is mapped as Kim-Thedalund Loams, 3-15% slopes. This is classified as a hydric soil. Five soil pits were used to define the limits of Wetland A. Pit 1was located outside the Corps of Engineers wetland but inside the zone of hydrophytic vegetation mapped as a City of Fort Collins Wetland. Pit 1 lacked hydric soil indicators or indicators of a wetland hydrology. Pit 2 was located in a disturbed soil the understory of the cottonwood trees north of the wetland, adjacent to an area of erosion control blanket (Photo 6). This soil was likely disturbed during the stormwater drainage improvements. The soil in the pit was hydric, with mottles and a Redox Dark Surface. However, it lacked hydrophytic vegetation and indicators of a wetland hydrology – so it was excluded from both wetland areas. The hydric soil in this location may be an artefact from the prior land uses, when this area was flood irrigated. A section of an old swale appears to have conveyed irrigation tailwater past these cottonwood trees, as shown by historical aerial photography. 6 Pits 3, 4, and 5 met all three indicators and they were all located inside the Corps of Engineers wetland boundary (Photo 5). All three pits contained a silty clay hydric soil with a Redox Dark Surface (Indicator F6) and oxidized rhizospheres on living roots. 4.2 West Study Area - Wetland B 4.2.1 Location Wetland B is the bottom of an old irrigation storage pond in the West Study Area, just west of the piped and abandoned segment of the North Louden Ditch (Photos 7 & 8). This pond could not be accessed during the delineation therefore the approximate wetland boundary was drawn in from aerial photography. Due to the steep banks at the margin of the pond, there is a sharp boundary between the upland and wetland habitats. In contrast to Wetland A, only one boundary was identified for Wetland B. Due to site conditions, it is assumed that the City of Fort Collins and Corps of Engineers would recognize the same boundary. The estimated area of Wetland B is 3,414 ft2 (0.08 acre). 4.2.2 Classification Under the Cowardin Classification System for Wetlands and Deepwater Habitats (Cowardin et al., 1979), Wetland B is in the Palustrine System, Emergent Persistent Class. 4.2.3 Vegetation Wetland B is characterized by a sparse cover of herbaceous wetland plants on the muddy bottom of the irrigation storage pond, which is evidently no longer used for this purpose (Photo 8). The dominant species appeared to be knotweeds (c.f. Persicaria lapathifolia). The perimeter of the pond supports a woody overstory of native and introduced species. There are several Siberian elms (Ulmus pumila), green ash (Fraxinus pensylvanica) and Russian olive trees, and one smaller plains cottonwood, with larger, mature cottonwoods located east of Pond B along the old ditch. Choke cherry (Prunus virginiana) and staghorn sumac (Rhus typhina) are also common at the perimeter of the pond inside the fenced enclosure. Smooth brome dominates the herbaceous understory. No wetlands were identified in the North Louden Ditch (Photos 9 & 10). This area had an overstory of plains cottonwood, Russian olive and buckthorn (Rhamnus cathartica) with smooth brome, prickly lettuce (Lactuca serriola), wild licorice (Glycyrhiza lepidota), and common sunflower (Helianthus annuus) in the understory. 4.2.4 Hydrology The adjacent segment of the North Louden Ditch is no longer used and therefore the diversion structure is not used to fill the irrigation storage pond (Photo 10). It did not have any water at the time of the delineation, and it is not known if the pond will continue to have sufficient water to support Wetland B in the future. A small, partially buried culvert was identified near the southern end of the pond by Gateway Center Drive during the wetland delineation, which could potentially carry a small volume of stormwater runoff towards the pond. 4.2.5 Soils As illustrated by Figure 4, the irrigation storage pond and segment of the North Louden Ditch are located within an area mapped as Kim Loam. This is a hydric soil type. 7 Pits 6 and 7 were both dug in the bottom of the abandoned segment of the North Louden Ditch east of Wetland B. Pit 6 was dug near Skyway Drive and had a Depleted Matrix (Indicator F3) (Photo 9). However, it lacked indicators of a wetland hydrology and it did not support hydrophytic vegetation. Pit 7 was dug just below the old irrigation diversion headgate (Photo 20) and also had a Depleted Matrix, as well as oxidized rhizospheres on living roots, but lacked hydrophytic vegetation (Photo 10). This ditch no longer is used and it does not have a wetland hydrology – and it should be noted these are recent changes. 5.0 ANALYSIS OF JURISDICTIONAL STATUS The jurisdictional status of Wetlands A and B depends on the connectivity and flow through culverts which may connect these wetlands to other waters of the U.S. Additional data are needed to evaluate this potential connection. However, regardless of the hydrologic connection, Wetlands A and B would be considered regulatory according to the guidance in Section 3.4.1 in the City of Fort Collins Land Use Code (2019). 6.0 EVALUATION OF THE EAST PARCEL FOR HABITAT MITIGATION As discussed above in Sections 2.0 and 4.1, there have been a number of hydrologic changes that affect the area of Wetland A and the remainder of the East Study Area. It appears that there is an influence of groundwater in this area, which has also been supplemented or augmented by irrigation tailwater collecting in a topographic depression, as well as stormwater runoff. The site no longer has an agricultural land use and there is no longer a contribution from irrigation tailwater. Additionally, recently installed stormwater culverts will introduce a new source of water. The site has not yet had time to adjust to these hydrologic changes – in particular the plant community has not yet responded and there will be changes to the soil moisture availability – perhaps the amount and location of the wetter areas. These factors are important when considering the site for use as a mitigation area. They affect the plant species which should be used and the restoration potential - and should be used to develop appropriate goals. 8 7.0 FIGURES ± MarsMap Landing Figure Offsite 1.

Pit 7 is near the old headgate in the North Louden Ditch. This segment of the ditch no longer carries irrigation water, since it was piped. The buried pipeline corridor crosses through the West Study Area parallel to Gateway Center Drive. (1/29/20). 23 10.0 REFERENCES Ackerfield, J. 2015. The Flora of Colorado. BRIT Press, Ft.
