(Terracon) conducted a wetland delineation on May 10 and June 7, 2018 for a parcel of land (herein referred to as “site”) located southeast of Redwood and Conifer Streets in Fort Collins, Colorado (Appendix A, Exhibit 1). The purpose of this report is to present the results of the wetland delineation. The 29-acre parcel is part of student-oriented housing development proposed by Landmark Development. The site adjoins Redwood Meadows and is northwest of the proposed Northfield subdivision adjacent to Lake Canal to the east. Construction at the site is expected to begin in late 2018 or early 2019. An Ecological Characterization Report (ECR) was prepared by Terracon on March 2, 2018 for LCD Acquisitions, LLC (client) per City of Fort Collins (City) Land Use Code Article 3: General Development Standards, Section 3.4.1 – Natural Habitats and Features. As part of this ECR, potential jurisdictional wetlands were identified to the northeast and northwest of the site. At the time of the ECR survey, no wetlands were identified on-site. Per City of Fort Collins land use code Section 3.4.1, a 100-foot buffer is required for all potential wetland areas that may be adjacent to construction sites. Additionally, a pedestrian crossing is proposed for Lake Canal and an access driveway is proposed to connect the site with Conifer Street to the north. As such, this report summarizes the findings of a wetland delineation for these areas adjacent to the site that may require 100-foot buffer and/or permitting with the U.S. Army Corps of Engineers. Pursuant to discussions held with the City on April 18 and May 31, 2018, the City is requesting a Jurisdictional Determination (JD) from the U.S. Army Corps of Engineers (USACE) for Lake Canal and vicinity, including potential wetlands, including Waters of the U.S. (WOTUS), to the north of the site. This report summarizes findings of the wetland determination in accordance with the U.S. Army Corps of Engineers (USACE) 1987 Wetland Delineation Manual. Additionally, all work performed for this delineation follows the USACE 2010 Great Plains Regional Supplement. The area surveyed for this delineation report only includes lands onsite or immediately adjacent to the site. This report has been prepared for the exclusive use and reliance of LCD Acquisitions, LLC (c/o Williams and Associates, e.g., “client”). Use or reliance by any other party except a governmental entity having jurisdiction over the site is prohibited without the written authorization of the client and Terracon.

The limitation of liability defined in the Master Services Agreement is the aggregate limit of Terracon’s liability to the client and all relying parties. 2.0 SCOPE OF SERVICES Terracon performed the following scope of services: n Reviewed topographical, National Wetlands Inventory, and aerial photograph resources to assist with identifying aquatic resources, wetland areas, and floodplains at the project site. n Mobilized to the site to conduct the site visit. n Prepared a map showing approximate locations of observation points and wetlands observed during the site visit. n Completed a Wetland Delineation Report (included herein) that included site characterization information, and a discussion of applicable data. 3.0 ENVIRONMENTAL SETTING 3.1 Specific Features of the Site The Retreat site is approximately 0.75 miles north of Old Town Fort Collins, in Larimer County, Colorado. Surface ownership is private. The elevation of the site is approximately 4,960 feet (ft) above sea level, and surrounding areas include Redwood Meadows subdivision and adjacent residential development. The proposed Northfield subdivision is located to the east, on the other side of Lake Canal. Additionally, the area to the west includes the Northeast College Corridor Outfall Project (NECCO), which consists of a 10-acre regional detention and water quality pond flowing through stormwater box culverts and draining into Dry Creek south of Vine Drive, adjacent to Redwood Street. Lake Canal, which was constructed in the late 1800s, flows diagonally from southwest to northeast along the site’s eastern boundary. Additionally, a stormwater detention structure is located to the northwest of the site, which collects runoff from adjacent neighborhoods and roadways. This structure (i.e., empty grass-covered pond) connects to a stormwater ditch located on the northern boundary of the site. This ditch connects to Evergreen pond to the northeast, which ties in with the City’s stormwater sewer system along Lemay Street. Water from this stormwater ditch system eventually drains to dry, open farm fields east of Lemay Street. The ground surface of the site is generally vegetated, except for adjacent roads. Dominant vegetation is typical of the Poudre River valley and Fort Collins vicinity. Primary plant species at Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 3 the site and adjacent wetlands include great plains cottonwood (Populus deltoides), Russian olive (Elaeagnus angustifolia), green ash (Fraxinus pennsylvanica), smooth brome (Bromus inermis), intermediate wheatgrass (Thinopyrum intermedium), Nebraska sedge (Carex nebrascensis) and reed canary grass (Phalaris arundinacea). Adjoining neighborhoods contain a mix of native and non-native vegetation. Riparian vegetation is located along the Lake Canal corridor and within the stormwater features to the north of the site. 3.2 General Features of the Project Site The climate is semi-arid, with relatively cool winters, and hot summers. Mean annual precipitation is approximately 16 inches (in) and average annual temperature is 50° Fahrenheit (F) (NWS 2018). The geology of the region consists alluvial material associated with the Cache La Poudre River and sedimentary material with aeolian/loess deposits. The site is located in the central high plains of the northern portion of the Colorado Piedmont section of the Great Plains. Commercial agriculture historically dominated the Poudre Valley as a result of access to irrigation and water supplies, gently sloping topography, and deep, nutrient-rich soil. Recently, former agricultural lands have been subdivided into residential and student-oriented housing to accommodate the growing population of the City of Fort Collins. 4.0 PRELIMINARY DATA GATHERING AND ANALYSIS Prior to performing the site visit, several maps and aerial photographs resources were reviewed to assist with identifying suspect surface waters and wetlands on the project site. Each source of data is described in detail below. 4.1 Topographic Map The U.S. Geological Survey (USGS) 7.5-Minute Topographic Map of the project site (Fort Collins, Colorado Quadrangle) was reviewed to identify drainages or potential aquatic resources (Appendix A, Exhibit 2). According to the topographic map, the project site appears to slope generally east/northeast. The topographic map depicts the majority of the project site as open meadow with little topographical variation across the site. The topographic map depicts Lake Canal, Dry Creek, and adjacent subdivisions. According to the topographic map, no aquatic sites or wetlands are located on the site. 4.2 National Wetlands Inventory Map The National Wetlands Inventory (NWI) Map of the project site was reviewed to identify suspect wetland areas and waterbodies within the project site boundaries. The map was published by the U.S. Department of the Interior’s Fish and Wildlife Service (USFWS) and depicts suspect wetland areas and waterbodies based on stereoscopic analysis of high altitude aerial photographs. It is Terracon’s understanding that the published data is not regularly updated and has not been Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 4 validated in the field. A NWI map is included as Exhibit 3 in Appendix A. The NWI map depicts Lake Canal along the east boundary of the site, the stormwater detention structure to the northwest and the City’s Evergreen Pond to the northeast. Dry Creek is depicted offsite to the south. 4.3 Soil Survey The Natural Resources Conservation (NRCS) web soil survey (NRCS 2018) was reviewed for soil information for the project area. A soil map is included as Exhibit 4 in Appendix A. The presence of hydric soils can indicate the potential for wetlands and/or aquatic resources. Based on the site visit, the soils are predominantly clay loam. No hydric soils are located onsite. Soils at the site are deep and and are typical of alluvial valley floor floodplain soils. The NRCS soils mapped for the site include the following: Caruso clay loam (0-1% slopes), Fort Collins loam (0-1% slopes), Loveland clay loam (0-1% slopes), Nunn clay loam (1-3% slopes), and Nunn clay loam, wet (1-3% slopes). Test plots for the wetland delineation confirm the presence of these soil types at the site. Loamy soils with gravelly substratum dominate the site. Portions of the site may have been historically tilled due to agriculture; therefore, the site contains soils with mixed/unstratified horizons in the upper one to two feet. Additionally, portions of the Lake Canal berm and stormwater detention pond/drainage may consist of non-native fill or alluvium since these areas are man-made. 5.0 FIELD METHODOLOGY Terracon personnel conducted a wetland delineation of the site on May 10 and June 7, 2018 to characterize existing site conditions and identify the presence of potential wetlands and waters, if any. Characteristics of wetlands and aquatic resources were assessed by using the United States Army Corps of Engineers’ (USACE) 1987 Wetland Delineation Manual and Great Plains Regional Supplement (USACE 2010). The Great Plains Regional supplement is used to identify specific wetland features unique to areas with low precipitation located in the western U.S. 5.1 Wetland Observations The USACE defines “wetlands” as “those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas” (33 CFR 328.3b). Wetlands generally have three essential characteristics: hydrophytic (wetland) vegetation, hydric soils, and wetland hydrology. Aside from adjacent areas (i.e., Lake Canal, Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 5 stormwater detention structure, ditches, etc.), suspect wetland areas were not identified within site boundaries based on aerial photographs, topographic maps, and NWI maps. During the site inventory, Terracon personnel traversed the entire project site as well as adjacent areas (i.e., Lake Canal, stormwater detention structures, ditches, etc.) and identified areas with the potential to contain wetland characteristics. Upland areas and/or areas lacking the potential to contain wetlands (i.e. hillslopes, residential neighborhoods, roadways, etc.) were assumed to be non-jurisdictional. Data regarding the three essential characteristics were gathered within observed suspect wetland areas, if any, to further delineate boundaries. Wetland determination data forms are presented in Appendix B. Data for 18 separate locations were collected for the site. Initial assessments for 13 locations were conducted on May 10, 2018. Although vegetation had matured at the time of the first site visit, irrigation flow in Lake Canal had not yet commenced. It was decided that a second site visit was warranted to account for additional hydrology (either surface or subsurface) that could result from the canal. As such, an additional 5 locations were sampled along the boundaries of the canal to evaluate the presence or absence of “fringe” wetlands. No wetland determination data points were collected from Evergreen Pond, as it is outside and greater than 100 feet from the property boundary. 5.1.1 Plant Community Assessment Suspect areas were visually observed to determine the species, when possible, and absolute percentage of ground cover for four strata of plant community types. Herbs were generally observed within a 2-meter square (m2) radius, shrubs/saplings within a 5-m2 radius (as applicable), and trees and woody vines within a 10-m2 radius (as applicable) of the observation location. For each plant species observed, their wetland indicator status was evaluated. The indicator statuses were determined using the USACE National Wetlands Plant List (NWPL). Indicator status categories for vegetation are presented below: n Obligate Wetland (OBL) – occur almost always (estimated probability greater than 99%) under natural conditions in wetlands. n Facultative Wetland (FACW) – usually occur in wetlands (estimated probability 67%-99%) but occasionally found in non-wetlands. n Facultative (FAC) – equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66%). Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 6 n Facultative Upland (FACU) – usually occur in non-wetlands (estimated probability 67%-99%) but occasionally found in wetlands. n Obligate Upland (UPL) – rarely occur in wetlands, but occur almost always (estimated probability greater than 99%) under natural conditions in non-wetlands. The percent cover of each stratum was determined and dominance was evaluated. Dominant species were the most abundant species that accounted for more than 20 percent of the absolute percent coverage of the stratum. The number of dominant species with an indicator status of OBL, FACW, and/or FAC was compared to the total number of dominant species across all strata. Typically, when more than 50 percent of the dominant species had an indicator status of OBL, FACW, and/or FAC, hydrophytic vegetation was present. If the percentage of dominant species with an indicator status of OBL, FACW, and/or FAC was less than 50 percent, prevalence index and morphological adaptations may have been evaluated to confirm if hydrophytic vegetation was present or absent. 5.1.2 Hydric Soils Assessment After Terracon evaluated wetland vegetation, subsurface soil samples were evaluated. The samples were evaluated to a depth of approximately 20 inches below ground surface and were visually compared to Munsell Soil Color Charts (Munsell 2009). Due to the timing of the delineation (February), several soils pits were shallower than 24 inches due to the presence of frozen soil. Field Indicators of Hydric Soils in the United States manual (NRCS 2017) was utilized to aid in the evaluation and identification of hydric soils indicators. The soil samples were further examined for hydric soil indicators including, but not limited to, histosols, thick dark surface, sandy gleyed matrix, sandy redox, loamy gleyed matrix, redox dark surface, and/or redox depressions (i.e. mottling). If these or other hydric soils indicators were observed in the subsurface soil sample, the observation location was considered to have hydric soil. 5.1.3 Wetland Hydrology Assessment Visual indicators of wetland hydrology were evaluated. Examples of primary wetland hydrology indicators include, but are not limited to, surface water, high water table, soil saturation, water marks, sediment deposits, drift deposits, iron deposits, inundation visible on aerial imagery, and water-stained leaves. Examples of secondary wetland hydrology indicators include, but are not limited to, surface soil cracks, drainage patterns, water-stained leaves, and drainage patterns. If at least one primary wetland hydrology indicator or two secondary wetland hydrology indicators were observed, the observation location was considered to have wetland hydrology.

Under normal circumstances, if one or more of the wetland criteria were not identified, the area was not considered to be a wetland. Additional observations were made throughout wetland areas (if present) to define the wetland/non-wetland boundary (only if wetlands were present). Vegetation, soil and hydrology assessment data from identified wetland areas were recorded on a USACE Wetland Determination Data Form. The recorded data forms (wetland determination data points 1 through 18) for the project site can be found in Appendix B and point locations can be seen on Exhibit 5 in Appendix A. Sample point locations are located throughout the site to evaluate the potential presence/absence of wetland characteristics. Due to the size of the site (e.g., 29 acres), 18 points were required to evaluate all potential wetlands. 6.0 SUMMARY OF FIELD OBSERVATIONS AND RESULTS On May 10 and June 7, 2018 Terracon performed field observations of the project site and identified areas to the north that contained wetland characteristics. Sample point locations are illustrated on Exhibit 5 (Appendix A) and the Wetland Determination Data Forms are provided in Appendix B. Site photographs, included in Appendix C, provide an indication of the physical characteristics observed during the site visits. Descriptions of the determination data collected at each point are provided below. 6.1 Summary of Wetland Determination Field Data Point 1 – Non-wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 1 was located in the stormwater detention structure to the northwest of the site. This catchment basin, which is part of the City’s stormwater management program, drains stormwater runoff from commercial facilities and residential neighborhoods north of Conifer Street. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 1 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018. Therefore, wetland hydrology is not present at this location. The location of Point 1 (i.e., southeast corner of detention basin) is at the far end of the basin that is unlikely to accumulate or pond water except during extreme precipitation events. Point 1 lacked positive indicators for all three criteria, therefore this point is not located within a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 1, Appendix C.

Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 2 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018. Therefore, wetland hydrology is not present at this location. The location of Point 2 (i.e., southwest corner of detention basin) is at the far end of the basin that is unlikely to accumulate or pond water except during extreme precipitation events. Point 2 lacked positive indicators for all three criteria, therefore this point is not located within a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 2, Appendix C. Point 3 – Non-wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 3 was located in the stormwater detention structure to the northwest of the site. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 3 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018, however drift deposits were observed. Therefore, wetland hydrology is present at this location. The location of Point 3 (i.e., north central part of detention basin) is located adjacent to areas with wetland characteristics. However, Point 3 lacked positive indicators for all three criteria, therefore this point is not located within a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 3, Appendix C. Point 4 - Wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 4 was located in the stormwater detention structure to the northwest of the site. A roadside ditch is located at Point 4. This ditch is part of the stormwater detention structure and collects runoff from Conifer Street. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 4 (Appendix B). Standing water, hydric soils, and hydrophytic vegetation was present at Point 4; therefore, this point is located in a wetland. This point was re- evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 4, Appendix C. Point 5 – Non-wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 5 was located in the stormwater detention structure to the northwest of the site. This point is located adjacent to Point 4, as an upland (i.e., non-wetland) comparison point. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 5 (Appendix B).

Point 5 lacked positive indicators for all three criteria, therefore this point is not located within a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 5, Appendix C. Point 6 - Wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 6 was located in the stormwater detention structure to the northwest of the site. Point 6 is located in the center of the stormwater structure, at the lowest point. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 6 (Appendix B). Standing water, hydric soils, and hydrophytic vegetation was present at Point 6; therefore, this point is located in a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 6, Appendix C. Point 7 – Non-Wetland As shown on Exhibit 5.0 (Appendix A), wetland determination data Point 7 was located in the stormwater detention structure to the northwest of the site. Point 7 is located just outside of the wetland created by the stormwater detention structure. This point is located between Points 1 and 6 in order to determine the wetland/non-wetland boundary. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 7 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018; therefore, wetland hydrology is not present at this location. Hydrophytic vegetation was present at Point 7; however, hydric soils were not present. Because this location lacked characteristics of all three criteria, Point 7 is not located in a wetland. This point was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 7, Appendix C. Point 8 – Non-wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 8 was located in the stormwater ditch to the north of the site. The stormwater ditch connects the northwest stormwater detention structure to Evergreen Pond to the northeast of the site. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 8 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 8 is not located in a wetland. Point 8 is a comparison point to Point 9, which is located in the bottom of the stormwater ditch. Point 8 was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 8, Appendix C.

The stormwater ditch connects the northwest stormwater detention structure to Evergreen Pond to the northeast of the site. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 9 (Appendix B). Although standing water was not present at this location, soils were saturated which is a positive indicator of wetland hydrology. Additionally, hydric soils and hydrophytic vegetation are present at this point. Point 9 is a comparison point to Point 8 (discussed above), which is located on the side-slope of stormwater drainage. This point is located within a wetland. Point 9 was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. A narrow fringe of hydrophytic vegetation helps to field-delineate wetlands in the bottom of the ditch. This point is shown in Photo 9, Appendix C. Point 10 – Non-wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 10 was located in the stormwater ditch to the north of the site. The stormwater ditch connects the northwest stormwater detention structure to Evergreen Pond to the northeast of the site. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 10 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated on May 10, 2018; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 10 is not located in a wetland. Point 10 is a comparison point to Point 11, which is located in the bottom of the stormwater ditch. Point 10 was re-evaluated during the June 7, 2018 site visit and conditions were observed to be the same as during the May 10 delineation. This point is shown in Photo 10, Appendix C. Point 11 - Wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 11 was located in the bottom of the stormwater ditch to the north of the site. The stormwater ditch connects the northwest stormwater detention structure to Evergreen Pond to the northeast of the site.

No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 15 is not located in a wetland. Point 15 is a comparison point to Point 14 (discussed above), which is also a non-wetland point. Point 15 was evaluated during the June 7, 2018 site visit. This point is shown in Photo 15, Appendix C. Point 16 – Non-wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 16 was located adjacent to Lake Canal to evaluate the potential presence or absence of fringe wetlands. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 16 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 16 is not located in a wetland. Point 16 was evaluated during the June 7, 2018 site visit following several weeks of flow in Lake Canal. This point is shown in Photo 16, Appendix C. Point 17 – Non-wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 17 was located adjacent to Lake Canal to evaluate the potential presence or absence of fringe wetlands. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 17 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 17 is not located in a wetland. Point 17 was evaluated during the June 7, 2018 site visit following several weeks of flow in Lake Canal. This point is shown in Photo 17, Appendix C. Point 18 – Non-wetland As shown on Exhibit 5 (Appendix A), wetland determination data Point 18 was located adjacent to Lake Canal to evaluate the potential presence or absence of fringe wetlands. Information for hydrophytic vegetation, hydric soils, and wetland hydrology is recorded on the determination data form for Point 18 (Appendix B). No standing water, surface water flow lines, or subsurface saturation was present at the time this point was evaluated; therefore, wetland hydrology is not present at this location. Because this location lacked characteristics of all three criteria, Point 18 is not located in a wetland.

Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 13 6.2 Wetland Summary Northwest Stormwater Detention Structure Positive indicators of wetland criteria were observed in the northern portion of the detention structure. A series of 7 points were used to delineate wetland boundaries in this area (Exhibit 5, Appendix A). Hydrology in this area originates from stormwater runoff from Redwood/Conifer Streets and residential/commercial areas to the north and west. Photos 19 through 22 (Appendix C) show the northwest stormwater area. A culvert (Photo 22) connects the stormwater area with the ditch. At the time the wetland delineation was conducted, water was not flowing through these culverts; however, sediment and drift deposits in this area indicate that stormwater does reach the ditch. Wetlands in the stormwater structure are limited to the northern portion of the basin. Points 1, 2, 3, and 7 were used to delineate the wetland/non-wetland interface in this area. The majority of the detention area is non-wetland. Wetlands in this area comprise 0.53 acres. Stormwater Ditch The stormwater ditch extends from the northwest stormwater detention structure to the east approximately 1,480 feet to a series of culverts that connect with Evergreen Pond. The ditch drains excess stormwater from points to the west and north. Photos of the ditch are shown on Photos 23-25 (Appendix C). A series of wetland determination data points were collected along the entire length of the ditch to determine wetland extent. A wetland is located in the bottom of the ditch along its entire length. Points 8-13 were used to delineate wetlands in this area. Wetlands in the ditch comprise 0.51 acres. Evergreen Pond Potential wetlands in Evergreen Pond were not evaluated because this area is located further than 100 feet from the property boundary. However, since this area is hydrologically connected with the northwest stormwater detention structure and the stormwater ditch, it was qualitatively evaluated. This area serves as a retention pond for stormwater runoff from neighborhoods adjacent to Redwood and Conifer Streets. A photo of the pond is shown on Photo 26 (Appendix C). This area is approximately 1.72 acres in size and consists of open water and fringe wetlands comprised of cattail (Typha latifolia) and cottonwood (Populus deltoides). An outlet structure is located in the southeast corner of the pond that consists of a concrete box with metal grate. Water in this outlet flows through a below-ground culvert that crosses Lemay Street to the east. Excess stormwater is distributed to open farm fields to the east of Lemay Street. There appears to be no connection to either Lake Canal or other potential WOTUS. Lake Canal Potential wetlands were evaluated along the boundary of Lake Canal. An ordinary high water mark (OHWM) and top-of-berm are shown on Exhibit 5. The OHWM along the canal is established by the fluctuation of the water surface. It is shown by such things as a clear line impressed on the bank, shelving, changes in soil character, destruction of terrestrial vegetation, Wetland Delineation Report Retreat at Fort Collins ■ Fort Collins, Colorado June 29, 2018 ■ Terracon Project: 20187054 Responsive ■ Resourceful ■ Reliable 14 the presence of litter and debris or other features influenced by the surrounding area. A rim of hydrophytic vegetation exists along the OHWM consisting of reed canary grass (Phalaris arundinacea), cottonwood, cattail, and narrowleaf willow (Salix exigua). Exterior to the berm, no wetlands exist. There is an approximate 8-10 foot drop from top-of-berm to the OHWM. Sample points 14-18 were used to collect potential wetland data for fringe wetlands formed adjacent to Lake Canal. Based on the results of these data, no wetlands exist immediately adjacent to the canal. Photos of the canal are shown on Photos 27-29 (Appendix C). On-site Positive indicators for the three wetland criteria (hydrophytic vegetation, hydric soils, and wetland hydrology) were evaluated for the site. No sampling locations exhibited wetland characteristics within site boundaries (Points 14-18). The site is dominated by smooth broom (Bromus inermis), which is classified as an upland plant in the Great Plains region. Leafy spurge (Euphorbia esula) and Russian olive (Elaeagnus angustifolia) are other common plants on-site. The site has likely been historically tilled and/or disturbed so problematic soils may be present. In order to account for this, additional points were located along Lake Canal to evaluate the potential affect that the canal may have on the creation of “fringe” wetlands. No fringe wetlands were observed either immediately adjacent to the canal or within the interior of the site. Additionally, topographic low spots (e.g., Points 14/15), were evaluated for saturation and/or standing water. The entire site is dry with no positive criteria for wetland hydrology in any portion of the site. Finally, to account for the effect of flowing water in Lake Canal, the site was evaluated before and after water had been turned on in the canal (e.g., May 10 and June 7, 2018). Water began to flow in Lake Canal in approximately the third week in May. Based on the lack of wetland hydrology following irrigation flow, Lake Canal does not appear to affect the formation of wetlands on-site. 7.0 CONCLUSIONS According to the inventory of the site, resource document review, and site visit observations, wetlands are located to the northwest and north of the site. The northwest stormwater detention structure contain approximately 0.53 acres of wetlands and the stormwater ditch contains approximately 0.51 acres of wetlands. Although surface hydrology is present in these areas, no flowing water was observed. It is likely that during high precipitation events, these structures fill with water and excess water flows into Evergreen Pond. Excess water in Evergreen Pond enters the City’s stormwater sewer and drains into open fields east of Lemay Street. As such, there does not appear to be a hydrologic nexus from the wetlands shown on Exhibit 5 to potential WOTUS or relatively permanent waters (RPWs). These wetland appear to be man-made and are associated with stormwater control structures. No naturally formed wetlands are located within the property boundary. No intermittent or ephemeral drainages or other aquatic areas were located or observed at the site. The OHWM for Lake Canal was used as a wetland boundary between the canal and the site. Future construction activities should avoid these areas.
