Mr. Ric Hattman October 10, 1997 Gefroh Hattman 145 W. Swallow Rd Fort Collins, Colorado 80525 Dear Mr. Hattman: At your request, Cedar Creek Assuciates, Inc. (Cedar Creek) completed a Corps of Engineers (COE) prisdictional wetland survey and delineation of a parcel of land located along South Mason Street in Fort Collins in the NE 1/4 of Section 3, T7N, R69W. The project area consists of two lots (approximately 1.08 acres) immediately north of the new Ramada Inn. This survey was conducted to fulfill the requirements of Section 404 of the Clean Water Act regarding the delineation of wetlands prior to potential development activities. Study Methodology Wetland mapping and delineation work was completed using the methods and techniques specified for "routine on -site delineations" in tha publication Corps of Engineers Wetlands Delirieatiorl Manual (1987). Prior to field work, project mapping was reviewed to familiarize field personnel with the project site, and a cursory examination of the property was made prior to field mapping to provide background information on any influencing circumstances as well as to allow verification of property boundaries and access points through the project area. Following reconnaissance work, normal mapping activity was initiated. To properly characterize the wetland, a sample point was selected in the Southwe.a quarter of the area whereby percent cover and cornposition of dominant plant species was estimated and a soil pit excavated. Only one sample point was deemed necessary to represent the overall wetland given the obvious nature of the wetland conditions. Species were classed as OBL (obligate wetland species), FACW (facultative wetland species), FAC (facultative species), FACU (facultative upland species) or UPL (upland species). Wetland soil indicators potentially included the presence of a histic epipedon, mottling, gleying, and high organic matter coniant and/or organic matter streaking in the surface layers of sandy soils. Potential wetland hydrologic indicators included topographic position, presence of standing water and/or saturated soil profile conditions, drainage patterns, and oxidized root channels in the upper 12 inches of the soil profile. A formal field data sheet was completed for the sampling point and is included with this document. CCIfi:D&M CCIIYlfOM k000CI<AT92, INC.

With regard to the remaining wetland, it is a combination of open water, cattail marsh, sedg,a-/grass meadow, and mudflat. At the time of survey, six mallards were utilizing the open water (approximately 12" - 18" deep) and raccoon tracks were observed along the shoreline. However, owing to the wetland's position within the confines of Fort Collins, in association with its small size, it does not offer significant value as wildlife habitat. The sample point placed in the southwest quadrant of the wetland area was selected to represent overall wetland conditions. This sample point is dominated by herbaceous wetland species which comprise 96% of the relative cover. Three species dominate at this point including Phalaris arundinacea, Typha latifolia, and Scirpus pungens with 20%, 15%, and 15% relative cover, respectively. As observable on the data sheet attached to this letter, several additional wetland species were noted within the sample point. Soil matrix colors are 10YR 3/2 to a depth of 8 inches and 10YR 3/1 from 8 to 16 inches, and 5Y 4/1 gleyed donditibns below 16 inches. Soil mottles in the upper 16 inches are abundant and strong exhibiting colors of 10YR 4/6. Free water was observedI in the soil pit at a level of 16 inches, saturated conditions were observed extending to the surface, and surface indications of springtime inundation are evident. - Once you have had a chance to review this inaterial, please give me a call if you have any questions. I am reasonably sure given that the project area is over 0.33 acres, the COE will likely require an individual permit for project development. Depending on the COE's requirements as they relate to this project,, such a permitting effort may be relatively easy or may become more involved. We cannot tell_ until further discussion with COE has occurred. If wi can help you with this permitting, F ease let us know, however, for your planning purposes you should be aware that our schedules in the near term are quite busy. I hope that this meets your needs at this time. Sincerely, CCIEIIDAB (CILR1912M k200CUMM,1NC. i Steven R. Viert Principal CC31DAM CCI!' 31111 k000C A' l&0, INC. Page 3 Gefroh Hatimari In conjunction with the formal sampling site, several "check holes" were excavated to further aid in the wetland delineation. Check holes provided additional soil and hydrologic information useful for refining boundaries indicated by surface vegetation patterns extant about the wetland area. Such information was also used to better characterize wetland conditions as a whole. Formal sample site data sheets were not completed for check holes. Following the analysis of site characteristics, the currently existing wetland boundary was marked with orange flagging. It is expected that these locations will be formally recorded through land surveying efforts provided by Gefroh Hattman or other contractor. The results of these field analyses are summarized in the following section. Results Overall, the entire project area is composed of wetlands likely to be considered jurisdictional by the COE or fill material which has been placed over wetlands, perhaps without proper authorization. If these areas of fill, were unauthorized by the COE, then the entire property would count toward the acreage classifying as wetland. In essence, it appears that the wetlands present within the confines of this property are all that remains of a much larger wetland which historically existed in the area. . As observable on Figure 1 and readily apparent in the field, it appears that when Mason street to the east was constructed, wetlands underlying the street's planned location were destroyed. Furthermore, on the east side of the property, a large amount of fill material has been deposited within a half-moorashaped area exhibiting dimensions of approximately 58 feet (east to west) and 147 feet (north to south). Similarly, the older development along north boundary of the property exhibits at least four vertical feet of fill material overlying the weti:nd area. This fill extends into the property a distance ranging from two to five feet. To the west, the existing railroad grade appears to have been constructed over the historic wetland. The.edge of the railroad right-of-way (i.e. boundary of the subject property) is difficult to determine in this area due to the existence of a tall and dense cattail marsh which is continuous with the wetland internal to the property (see Figure 1). To the south, the recent construction for the new Ramada Inn was facilitated by placement of up to an estimated six vertical feet of fill material which also extends into the subject property from two to ;c: f,: at. As a result of these fills, the existing expression of wetland is substantially reduced iron, its historic buundaries. This remaining expression of wetland was flagged by Cedar Creek on October 8, 1997. If the aforementioned fills were authorized by the COE, then the flagged boundary is the only area which must be addressed by 404 permitting efforts. If any of the four fill areas were unauthorized by the COE, then that portion of the property could also count as wetland area. The most conservative call in this Ca D.UTA (CRIZE919 INC.
