Survey Organization/Agency: Pinyon Environmental Address: 3222 South Vance Street, Lakewood, CO, 80227 Principal Investigator: Thomas Carr Principal Investigator's Signature: ______________________________ 5. Lead Agency: City of Fort Collins Land Owner: City of Fort Collins 6. Client: CivilWorx, LLC. 7. Permit Type and Number: Colorado Archaeological Permit, State Wide Survey 2019-73801 Report / Contract Number: 119126001 9. Comments: None II. DESCRIPTION OF UNDERTAKING / PROJECT 10. Type of Undertaking: The project would install a new 20-inch diameter waterline approximately six feet underground. The typical trench section would be about six-feet wide with a trench box. Soil stockpiles, vehicle traffic, and surface disturbance would be limited to 30-feet on either side of the waterline. This 60-foot-wide area along the waterline comprises the project area. Conventional excavation equipment, including diesel-powered hydraulic excavators and front- end loaders would be used to construct the new waterline. 11. Size of Undertaking (acres): 8.26 Acres Size of Project (if different): NA 12. Nature of the Anticipated Disturbance: Excavation of soil to approximately six feet deep for the construction of a water pipeline. 13. Comments: None III. PROJECT LOCATION Please attach a photocopy of USGS Quad. clearly showing the project location. The Quad. should be clearly labeled with the Prime Meridian, Township, Range, Section(s), Quad. map name, size, and date. Please do not reduce or enlarge the photocopy. 14. Description: The project is located at the western edge of the City of Fort Collins, in Larimer County, Colorado within the Maxwell Natural Area. The survey area begins at the entrance to the Maxwell Natural Area and ends at two large water tanks, approximately .73-miles to the northwest. 15. Legal Location: Quad. Map: Horsetooth Reservoir, 1962 Principal Meridian: 6th NOTE: Only generalized subdivision ("quarter quarters") within each section is needed Township: 7N Range: 69W Sec.: 17 SE 1/4s & SW 1/4s If section(s) is irregular, explain alignment method: NA 16. Total number of acres surveyed: 8.26 Acres 17. Comments: Final design has not yet been completed for this project, and potential impacts are unknown at this time. However, several programmatic agreements (PAs) have been developed exempting the USACE from Section 106 consultation for certain project actives for which this project may qualify. IV. ENVIRONMENT 18. General Topographic Setting: The general setting is foothills transition zone with mixed grass and scrubland. The natural drainages have been heavily modified by the Big Thompson Project, but in general the area water feeds into the Cache La Poudre River, located to the north of the project area. Current Land Use: City of Fort Collins Natural Area 19. Flora: The area is mostly mixed grass, generally comprising of these species: blue gramma (Bouteloua gracilis), little bluestem (Schizachyrium scoparium), needle-and-thread (Hesperostipa comata), green needle grass (Stipa viridula), scurfpea, scarlet globemallow (Sphaeralcea coccinea), and yucca (yucca glauca). The area also contains mountain mahogany (Cercocarpus montanus) rabbit brush (Chrysothamnus nauseosus), three-leaf sumac (Rhus trilobata) and some woods rose (rosa woodsii). 20. Soils/Geology: The eastern portion of the survey area consists of Nunn series clay loam and Kim series loam, while the western portion is primarily Satanta series loam up against Haplustolls rock outcrop complexes. 21. Ground Visibility: Ground visibility varies between 10% and 50%, with most of the survey area covered by thick grasses. 22. Comments: None V. LITERATURE REVIEW 23. Location of File Search: OAHP/COMPASS, USGS online Date: April 25, 2019 24. Previous Survey Activity - In the project area: There have been two previous surveys that crosscut small sections of the study area by Bill Butler (1999) and Mary Painter (2004). In the general region: There was also a large-scale survey of the area around Horse Tooth Reservoir located to the west by Robert Mutaw (1990). 25. Known Cultural Resources - In the project area: A review of the COMPASS database maintained by the Office of Archaeology and Historic Preservation (OAHP) indicated no known or previously surveyed archaeological resources within the study area. Newly identified archaeological resources were not located during a pedestrian survey of the project area. A review of the COMPASS database maintained by OAHP indicated one previously recorded historic resource in the study area – the Dixon Feder Canal (5LR.1346). The Dixon Feeder Canal is a supporting component of the Colorado Big Thompson Project National Register Historic District (5LR.9611). Historic linear resources are typically treated as historic resources, even when they have associated historical archaeological features. No associated historical archaeological features were observed in this survey. The Dixon Feeder Canal was constructed in 1950 under authorization granted by Presidential approval dated December 21, 1937, which approved the Secretary of the Interior's Finding of Feasibility for the Colorado-Big Thompson Project. The canal was constructed to replace private facilities that diverted water from Dixon Creek and were destroyed by construction of Dixon Canyon Dam (CBTE004). The contract for construction of the Dixon Feeder Canal was awarded to Lindstrom & Williams on July 20,1950. The canal was completed by the end of 1950. This resource and other Big Thompson resources in the general area are discussed by Laurie Summons (1999). As of the date of this survey, the condition of the canal appears to be good and appears to have been recently cleared of debris. The newly constructed pipeline would pass underneath the Dixon Feeder Canal and parallel it for approximately 320-meters. Trenching through the canal may be required to accommodate new waterline construction. The pre-construction contours of the ditch would be restored within 30 days of completion of the work. If impacts to jurisdictional Waters of the US (WUS) are anticipated from project activities, impacts to WUS should be quantified and submitted to the USACE in a request for authorization under Section 404 of the CWA. Should a 404 permit be required, project work meets the requirements of “Appendix 1, Item 1: Trenching Through a Ditch” contained in the Programmatic Agreement among the United States Army Corps of Engineers, Albuquerque District, the United States Army Corps of Engineers, Sacramento District, the United States Army Corps of Engineers, Omaha District, the Colorado State Historic Preservation Officer, and the Advisory Council on Historic Preservation Regarding Standard Treatment of Ditches Determined Eligible for inclusion on the National Register of Historic Places and Certain Exempt Activities in the State of Colorado [USACE Standard Treatment of Ditches PA]. Therefore, this project would be exempt from Section 106 consultation. In the general region (summarize): Some of the resources identified by Mutaw (1990) to the west of Horsetooth Reservoir included various isolated prehistoric lithics such as biface fragments, prehistoric open camps and lithic scatters, historic occupations, historic trash scatters, and stone quarries. No resources of this nature are recorded for the current study area. 26. Expected Results: Based on the previous survey data, the existing Dixon Feeder Canal was the only resource know to be in the study area. Based on the sites documented by Mutaw (1990), there was also the possibility of undocumented prehistoric lithic scatters. VI. STATEMENT OF OBJECTIVES 27. The main objective was to visually survey and identify any cultural resources that might be impacted by the proposed drainage improvements. Any resources would need to be evaluated for their potential eligibility for listing on the National Register of Historic Places, and to make management and/or mitigation recommendations. VII. FIELD METHODS 28. Definitions: Prehistoric site – any locality exhibiting structures or features (e.g., stone circle or hearth) or having five or more artifacts in apparent association with one another and occurring within a restricted area. Historic site – any structural remnant (e.g., house, outbuilding, root cellar), trash concentration or scatter suggesting residential or industrial use of the area, with a minimum age of 50 years. Prehistoric isolated find – nonstructural remains consisting of four or fewer artifacts. Historic isolated find – individual historic artifacts or small clusters of artifacts that do not represent established refuse dumps, with a minimum age of 50 years. 29. Describe Survey Method: The author walked two survey lines that paralleled the center line of the proposed pipeline course. VIII. RESULTS 30. List IFs if applicable. Indicate IF locations on the map completed for Part III. No isolated finds were observed. 31. Using your professional knowledge of the region, why are there none or very limited cultural remains in the project area? Is there subsurface potential? It is my professional opinion the limited identification of cultural resources in the study area is due to the relatively low site density for the surrounding region. The likelihood of encountering buried archaeological deposits is low. It is recommended to use caution when working around the Dixon Feeder Canal to avoid disturbing this resource.
