M.A., RPA, SWCA Cultural Resources Technical Director Melanie Medeiros, M.A., RPA, SWCA Cultural Resources Principal Investigator Date: October 25, 2022 Re: Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado / SWCA Project No. 76147 J&T Consulting, Inc. (J&T Consulting) contracted SWCA Environmental Consultants (SWCA) to conduct a cultural resource review and reconnaissance survey to support the proposed Fairmeadows RV Storage Facility and Gravel Mining Pit Project (project). The project consists of the new construction of a recreational vehicle (RV) storage yard and gravel mining pit on an approximately 86 -acre lot (Parcel No. 096103300067), hereafter referred to as the project area, in Greeley, Colorado, on mostly undeveloped farmland owned by Sunset Industrial, LLC (Sunset Industrial) (Figures 1 and 2). Development of the RV storage facility, which will cover approximately 25 percent of the parcel, will be subject to permitting through Weld County, and development of the gravel mining pit, which will cover the remaining 75 percent of the parcel, will be subject to permitting with both Weld County and the State of Colorado. The purpose of the review and reconaissance survey is to assess the project area for the presence of archaeologically and potentially sensitive cultural areas to assist J&T Consulting and the project proponent in determining if any pre-existing cultural resource issues may impact the project and to support both the county -level and state -level project permitting. This technical memorandum provides a description of the project area and land use, the methods used by SWCA cultural resources specialists to complete the review and reconnaissance survey, a summary of the results of the review and the reconnaissance survey, and recommendations as they relate to the proposed project. PROJECT AREA AND LAND USE The project area is located northeast of the East 8th Street / Colorado State Highway 263 and Weld County Road 43 intersection at 1507 East 8th Street in Greeley, Weld County, Colorado, on the west side of Section 3 of Township CT) 5 North (N), Range 65 West (W), as depicted on the 1950, 1980 photorevised, U.S. Geological Survey (USGS) Greeley, Colorado, 7.5 -minute quadrangle (see Figures 1 and 2). Aerial imagery of the project area depicts the parcel as an approximately 50 -percent -disturbed (mechanically graded) open farm field within the irregularly shaped parcel, surrounded on the north and east by low-rise hills covered in open grasslands and sparse tree clusters. A series of four building clusters are at the base of the low hills. Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley.

Project area, showing the proposed RV storage and mining pit areas, overlaid on aerial imagery. 3 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado The southern portion of the property, where the gravel mining operation is to be located, is an open agricultural field that is currently fallow and bare. That field is on a lowland terrace of the Cache la Poudre River, the channel of which is 0.2 mile south of the property, across East 8th Street. Soils in the project area are characterized as Aquolls and Aquents, gravelly substratum; Ellicott -Ellicott sandy - skeletal complex, 0 to 3 percent slopes, rarely flooded; and Ustic Torriorthents, moderately steep (Natural Resource Conservation Service 2019). All of these soils consist of alluvial deposits of sand overlying gravelly sand. The reconnaissance survey confirms that the field lacks topsoil and has been affected by plowing into alluvial sediments consisting of cobbles, gravels, and sand. No soil horizon remains able to support subsurface archaeological materials. A few cornfields stand on the margins of adjacent properties; however, this portion of East 8th Street, on the east exurban edge of the City of Greeley, is primarily mixed industrial. Industrial complexes, including a multi -head oil/gas well, are across East 8th Street to the immediate southwest and southeast of the project area and on its west side. An oil/gas well is located in the southeast corner of the project area at East 8th Street. One oil well was on the northwestern edge of the property until between 2006 and 2010, and another oil well was on the northeastern edge of the field until between 2016 and 2017, based on Google aerial images (Google Earth 2022); these wells have since been reclaimed. The Greeley -Weld County Airport is immediately to the east and northeast of the project area. And an existing gravel mining complex is on the immediate south side of the Cache la Poudre River, south of the project area. PREVIOUS WORK On September 29, 2022, SWCA conducted a file search and literature review through the Colorado Office of Archaeology and Historic Preservation (OAHP) online database (COMPASS) to identify all previously conducted cultural resource inventories and all previously identified cultural resources within the Public Land Survey System section containing the project area. File Search Results of the OAHP file search indicate that three cultural resource inventories have been previously conducted in Section 3, T5N, R65W (Table 1). Two of these inventories were conducted for the nearby Greeley -Weld County Airport and the third was conducted for a large-scale fiber-optic project. None of the previous inventories intersect the proposed project location, although one of the surveys conducted for the airport (WL.FA.NR5) discusses the historic buildings located in the project area (see discussion below). The closest previous inventory (MC.CH.R88), conducted in 1999, is adjacent to the southern border of the proposed project location; spatial data for this project is not available for review on COMPASS. WL.FA.NR5, conducted in 1980, identified the project area as having been previously owned by Robert Davis, with original structures dating from 1900 having been demolished. In 1980 the project area was owned by the Fair Meadows Land Company and contained several structures. According to WL.FA.NR5 report author Kathleen A. Engels, "A ranch style dwelling with wood windows and a brick exterior on a concrete foundation was built in 1900. Other structures include a grain elevator which was constructed during 1948. Sheds, a stable, and other outbuildings typically associated with a farm were built during the 1930's" (Engels 1980:13). Engels concluded the Davis Farm should not be considered eligible for the National Register of Historic Places (NRHP) because it represents a style of architecture that is common to the area, and because the buildings are not integrally associated with any defined districts and do not represent a district when grouped together (Engels 1980:15). 4 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Table 1.

Asa result of these previous inventories, one cultural resource has been recorded and assigned a Smithsonian trinomial number, a segment of the historic Ogilvy Ditch (Table 2). Ogilvy Ditch (5WL2944) was built in 1881 and was recommended as eligible for both the NRHP and the State. Register of Historic Places (SRHP). The recorded segment of the ditch, 5WL2944.1, is located 80 feet south of the project area as it runs parallel to East 8th Street / Colorado State Highway 263 (Highway 263). No archaeological sites have been previously recorded within the project area. Of note and as discussed above, the Davis Farm was identified as being located in the project area in inventory report WL.FA.NR5. Although the farm was superficially assessed for historical significance in that report, the farm has not been formally recorded nor has it been assigned a Smithsonian trinomial number. Table 2.

GLO/Original Survey Plat 1865 Greeley, Colorado USGS 1:125,000 -scale quadrangle 1902 Greeley, Colorado USGS 1:24,000 -scale quadrangle 1950 Based on a review of the 1865 survey plat for Section 3, T5N, R65W, an unnamed trail bisects the section running southeast to northwest along the ridge in the northern part of the project area. The 1902 USGS Greeley, Colorado, 1:125,000 -scale quadrangle shows the project area to be 2 miles east of the developed part of the town of Greeley in the area of Pleasant Valley, with no buildings or other built features present. Just outside the project area is a robust network of inigation canals and one building located 350 feet southwest of the southwest corner of the project area. The 1950 USGS Greeley, Colorado, 1:24,000- 5 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado scale quadrangle shows the project area with many of its current features (see Figure 1), with a few variations. First, the access road branches off of Highway 263 and proceeds north to pass the houses and outbuilding, but instead of curving around the field and back into Highway 263, as it does today, the road continues north for half a mile to connect to Bliss Road. Second, a residence is shown within the project area northeast of the field, where the gravel pit is proposed, where none exists today. And third, the house at 1515 East 8th Street is not shown despite having been built in 1938, indicating that house may have been moved to its current location from within the project area. General Area History Greeley began as the Union Colony of Colorado (Union Colony), an experimental utopian farming community founded in 1869 by Nathan Cook Meeker, an agricultural reporter for the New York Tribune. Meeker and former Union Civil War General Robert Alexander Cameron were part of a committee that traveled to Colorado to find a location for their colony. They purchased 12,000 acres at the confluence of the Cache la Poudre and South Platte Rivers. The colony successfully attracted investors and settlers to buy lots that would then fund civic improvement. Union Colony leadership then established the town of Greeley in 1870. Greeley was named after Horace Greeley, the editor of the New York Tribune, who supported Meeker in creating the Union Colony and who popularized the phrase "Go West, young man." As the town grew, the farming community compensated for the arid climate by creating an extensive network of reservoirs and irrigation channels (Ely 1902; Kroepsch 2020; Worster 1985:83-84). The project parcel (Parcel No. 096103300067) is currently zoned industrial and owned by Sunset Industrial. In 2022, Sunset Industrial acquired the property through Fairmeadows Liquidation Trust, which had transacted the property previously with Stanley F. Davis (or his estate), according to Weld County Clerk and Recorder records online (Weld County 2022a). The portions of the southwest quarter of Section 3 and adjacent lands in T5N, R65W containing the project area were originally patented in 1894 through cash entry by Joel E. Davis, according to online GLO records (BLM 2022). Joel Edwin Davis (1831-1899) of Greeley should not be confused with another J. E. Davis who lived and farmed south of Greeley at Big Bend/Peckham, in the late 1800s and early 1900s. Joel Edwin Davis (Figure 3) was investing in lands around Greeley prior to 1894, according to the A History: Greeley and the Union Colony (Boyd 1890). J. E. Davis, .originally a confederate of the south, arrived in Greeley in 1873 and became a farmer and financier. He was primarily an investor and rented out his properties, according to Boyd (1890:413-414). Therefore, the Davis family does not appear to have resided on the land within the project area but was the landlord of a property that was rented from the beginning of its development. The Greeley Tribune, on August 10, 1899, noted Joel Edwin Davis's funeral and that "[h]e was known as one who treated his neighbors and tenants well." Various articles in the Greeley Tribune in the 1890s indicate J.E. Davis lived locally and that he held properties deeded from the Union Colony, although the proposed project area is outside the sited colony lands. At the time of his death, Joel Edwin Davis's home is noted by the Greeley Tribune to be at 7th Avenue and 10th Street. He died from the effects of a stroke suffered in 1896. Based on a Greeley Tribune article on April 14, 1898, this was his son Stanley's house (built in 1898). In 1908, his wife. Ella (age 78, n�e Northcross) is noted by the Greeley Tribune (January 16, 1908) as passing away at 828 Tenth Street, Greeley. Davis had one son, Mr. Stanley Davis of Greeley, and three daughters: Mrs. Lulu Burr of Greeley, Mrs. Nellie Patton of Boulder, and Mrs. Daisy Carney of Denver, according to his Greeley Tribune obituary. Stanley Davis and wife (n�e Harrington) had a son, Franklin (Colorado Historic Newspapers Collection [CHNC] 2022). Stanley continued to rent out farms and ranches in the area, as apparent from the Greeley Tribune in the early 1900s. According to FamilySearch, which compiles census and related data, this was Edwin. Stanley Davis (1868-1925), and he and his wife, Lida Harrington Davis (1872-1963), had one son, Franklin Burr Davis (1898-1951); Franklin had a son, Robert Stanley Davis (1929-1974), as well as two daughters (Intellectual Reserve, Inc. 2022). 6 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 3. Joel Edwin Davis, born 1831, died 1899 (Intellectual Reserve, Inc. 2022). Reconnaissance Survey On September 14, 2022, SWCA Cultural Resource Technical Director Scott Phillips completed a reconnaissance survey of the project area to identify cultural resources and potential impacts the project may have on those resources. As a result of this survey, four historic farmsteads-5WL9410, 5WL9411, 5WL9412, and 5WL9413—were recorded (Figure 4). 7 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project; Greeley, Weld County, Colorado Cultural Resource Project Area Proposed Mining aid Water Storage Cell RV Storage Section Boundary Weld County, CO USGS 7.5' Quadrangle: Greeley, CO, 40104-D6 5N 65W Section 03 NAD 1983 UTM Zone 13N 40.4267°N 104.6535°W Base Map.

Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Farmhouses and outbuildings line a driveway that trends north from where it intersects East 8th Street at the southwest corner of the parcel (Figure 5). These houses are on the north edge of the terrace where it meets a fallow field (Figure 6) and on the low rise of the next terrace north. Soils are poorly sorted alluvial sediments consisting of cobbles, gravels, and sand (Figure 7). Topsoil is generally absent in the project area and specifically at the buildings. The residential area has been used as rental housing into recent times and the area kept clean and free of trash and debris. No historic dumps or artifacts (no purple or other glass, ceramic, or metal debris, or miscellaneous building materials) are on -site. Storage piles on - site contain only cut cottonwoods from recent drought die -off events that intensified after 2012, based on Google Earth (2022) historic aerial imagery. The property currently has four residences with the addresses of 1507, 1515, 1519, and 1539 East 8th Street, with the address numbers increasing from southwest to northeast following the terrace edge. The brick house at 1539 East 8th Street appears to be the oldest and is likely the original farmhouse built around the turn of the twentieth century. This house is outside the gravel mining pit area but is adjacent to the proposed RV storage area. Its outbuildings and enclosed porch addition are wood -framed in a manner similar to the house immediately to the southwest. The house at 1519 East 8th Street likely represents a later expansion of the original farm complex, ca. 1938, according to Weld County Assessor records (Weld County 2022b), which is consistent with the building style.

Feature 1 is a wood -framed house originally on a rectangular footprint; however, that footprint has been misshapen by a shed -roofed addition to the back (north) of the house (Figures 8 10 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado and 9). The Weld County property assessment indicates that this house was built in 1905, and that date is supported based on the style of its original siding and framing apparent in the 2001 assessment photograph (Weld County 2022b). However, its foundation appears to be a robust concrete that may have been added or replaced later; it is possible, but unknown whether the house was moved to the property at a later date. The rear addition is obviously from after the original construction of the house; its east- northeast extent appears to have allowed for the introduction of an indoor bathroom. The back steps are wood replacement steps; the front porch is weathered concrete with a newer concrete sidewalk curving outward from it. Its siding has recently been replaced along with all windows and doors, a recurring trend for wood -framed houses on the property. The roof has been recently re -shingled in gray asphalt tiles, another recurring trend for houses on the property. Under the overhanging eaves of the roof, the exposed rafter ends are braced on the gable ends of the house. The front (south) and east side yards are fenced in a low chain link fence without a top rail, and the backyard has a higher chain link dog run. A propane tank is behind the house to the northwest. A multi -head gas well facility is a recent addition on the neighboring property to the northwest of the house. The house has no outbuildings associated with it. Figure 8. Site 5WL9410, Feature 1, house, view to the northeast. 11 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 9. Site 5WL9410, Feature 1, house, view to the southwest. Although the house is on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired the property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 5WL9411 -1515 East 8th Street SWCA newly recorded 5 WL9411, a historic farmstead at 1515 East 8th Street, consisting of a house (Feature 1) and garage (Feature 2). The house is wood -framed and on an irregular footprint. Based on Weld County records, the house was built in 1938, the same year as the house at 1519 East 8th Street (5WL9412), which is consistent with its construction style (Figures 10 and 11). Overall, the building has had additions through time, including a shed roof extension of the back (north) and a shed -roofed entry room on the northeast corner. The main, original house has a cross -gabled roof, and the original footprint would have been T-shaped. The eaves are enclosed, with no rafters exposed. Roof shingles are new gray asphalt tiles. Like the house discussed previously (1507 East 8th Street/5 WL9410), it is apparent from Weld County Assessor photographs from 2001 that earlier horizontal wood siding on this house has been replaced. The window openings have been refit with smaller aluminum -framed windows and the front door has been refit with a non -period door. The foundation is concrete as are the porches. Feature 2 is a concrete block garage that sits northeast of the house (see Figures 10 and 11). The garage has a double door (plywood) single entry in its south end. The Weld County Assessor photograph from 2001 shows this building as having a metal roll -up garage door. Several extensions have been added to the rear of this shed -roofed building, which has a corrugated sheet -steel roof. The yard of the house is fenced with low chain link fencing that connects from the garage to the house. 12 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 10.

Although the house and garage are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property 13 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 5WL9412 —1519 East 8th Street SWCA newly recorded 5WL9412, a historic farmstead at 1519 East 8th Street, consisting of a house (Feature 1), garage (Feature 2), concrete block outbuilding (Feature 3), Quonset hut (Feature 4), worker's cottage (Feature 5), and concrete building foundation (Feature 6). The house at 1519 East 8th Street will be left in place and kept as an employee residence for the project; however, the outbuildings on the property may be removed. Feature 1 is currently the only occupied residence in the series of houses on the project property (Figures 12 and 13). Based on Weld County records, the house was built in 1938, and its construction is consistent with that assessment. The house at 1515 East 8th Street (5WL9411) was also built in 1938. The house is now on an L-shaped footprint but appears to originally have been built rectangularly. An entryway wing on the southeast corner appears to be a later addition, as does a westward extension on the front of the main body of the house. The horizontal wood siding on the exterior walls appears to have been replaced throughout the building. The front (south) windows have all been replaced with more recent casement windows, whereas the side and rear facades retain double sash wood -framed windows. The roof is hipped on the east side, front -gabled over the entry wing, and end -gabled over the west fa�ade. Roof shingles are new gray asphalt; however, the adjacent garage (Feature 2) has older wood singles. A single brick chimney is centered on the roof. The eaves have exposed rafters. The foundation and porches are concrete. A crawl space opening is apparent at the front of the building. The door at the original front entry appears to be a recent replacement, although the door in the added entry wing appears to be older and original. Feature 2 is a garage immediately on the west side of the house (see Figures 12 and 13). The rectangular end -gabled single -bay garage is wood framed, like the house. However, its siding appears to be the original wood planks, and its wood roof shingles also remain. It has a double -entry door of vertical wood planks on its front facade (south). The rear (north) of the garage is composed of concrete blocks where it is built into the earth slope behind it. The concrete blocks have triangular support sections flaring from the base where the garage faces the slope. In front of the garage is a new, prefabricated garden shed, constructed to look like a small red barn. Similarly, a new small red barn —style chicken coop is located on the east side of the house. 14 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado .!1 -00.111Thd"jjaketr --n-s-414 Figure 12.

Three farm outbuildings are located on the entry drive to the house: a full concrete block building (Feature 3), a large corrugated steel Quonset hut (Feature 4), and a small modular worker's cottage (Feature 5). All three outbuildings are oriented at a 45 -degree angle off of north, with roof ridgelines 15 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado running southeast to northwest. This contrasts with all the house and garage buildings on the property that are oriented south and generally align to the cardinal compass directions. Feature 3 is a concrete block building that was likely used as a garage, shop, or equipment shed (Figures 14-17). Feature 3 is located approximately 300 feet southwest of the house (Feature 1), is aligned parallel and adjacent to the larger Quonset hut (Feature 4), and is the second concrete block building at the site besides the garage (Feature 2). The rectangular building has an end -gabled roof with horizontal wood siding under the gables between the roofline and concrete block wall. The roof is covered in corrugated steel roofing panels and the rafters are exposed at the eaves. The building has a double -bay set of roll -up garage doors on the southwest fa�ade. On the northwest and northeast fa�ades, it has paired, multi-lite double sash wood -framed windows with brick sills that have hardware mesh exterior screens bolted to the building's exterior.

Site 5WL9412, Feature 3 (concrete block building) north corner with back (northeast) fa�ade on left, and partial northwest fa�ade on right, view to the south. Feature 4 is a Quonset hut utility shed, a long rectangular building with an arched roof that continues downward to function as walls, creating a half -cylinder building volume (Figures 18-20; see Figures 14- 16). The Quonset hut is clad in corrugated steel with a two -door single bay entry centered on the southwest end. Two pairs of six-lite windows are set on either side of the entry bay, and a louvered air vent is set above the entry bay. On the east half of the southeast side of the outbuilding are six additional six-lite windows. The semicircular northeast fa�ade of the outbuilding has a similar bay opening and windows as the southwest end; however, the northeast fa�ade also has a corrugated steel —sided (shed - roofed) entry room added on its north corner. The entry room has the same six-lite windows as the main Quonset hut as well as a small cement -surfaced chimney on its northeast side (see Figures 16 and 18). The Quonset hut is consistent with Stran-Steel models (prefabricated kits) dating to World War II and after (Thomas 2003). Weld County's assessed date of 1950 for this building is likely accurate. 18 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 18.

Site 5WL9412, Feature 5 (worker's cottage) south corner, with Feature 4 (Quonset hut) on left, view to the north. Feature 5 is a small worker's cottage located south and across the dirt driveway from the Quonset hut (Figures 21 and 22; see Figures 14, 18, and 20). It is a modular unit on a rectangular concrete footprint. It appears to have been prefabricated at its current position to take advantage of electricity from the power pole, located off its northeast side. Another building was previously set in parallel to the northwestern side of the cottage; however, only a concrete foundation remains, including a covered well opening centered near the south side and abutting the cottage. The wood -framed cottage is clad in horizontal lapboard siding. It has an end -gabled roof and opens to the southwest through a wood doorway set in the west side of the southwest fa�ade, which has a double sash wood -framed window opening beside it. Double sash window openings are spaced along the other fa�ades as well; however, only one doorway exists. The cottage is for temporary housing only, with a sitting room and gas stove at the front and a bedroom at the rear. A single brick chimney is centered on the roof peak. A propane tank is located behind (northeast of) the cottage. 20 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 21. Site 5WL9412, Feature 5 (worker's cottage) at center, with Feature 6 (concrete building foundation) at far left, view to the east. Feature 6 is the remains of a concrete building foundation set parallel to the northwest side of the worker's cottage and adjacent to the dirt driveway road (see Figure 22). A covered well opening is centered near the feature's south side and abutting the cottage. Although the house and its outbuildings are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house has had incongruous changes and additions made, including additions that distort its shape and mass, replacement window openings, and changes to the siding and entry openings. The property lacks significance and integrity under any NRHP criteria. 21 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 22. 5WL9412, Feature 6 (concrete building foundation) at center, with Feature 5 (worker's cottage) at far left, and site 5WL9411 at in the center background, view to the southwest. 5WL9413 —1539 East 8th Street SWCA newly recorded 5WL9413, a historic farmstead at 1539 East 8th Street, consisting of a house (Feature 1), garage/shed outbuilding (Feature 2), outhouse (Feature 3), and well/pumphouse (Feature 4) (Figure 23). The buildings at 1539 East 8th Street are outside the planned mining permit area and are not planned for demolition as part of the gravel mining operations. However, according to the current owner, the viability of the house was challenged by a storm and treefall onto its roof sometime between 2019 and 2021; the former owner had been refurbishing the house for occupation until a treefall and resulting water damage destroyed that effort. It is apparent that roofing tiles were replaced between 2016 and 2017 based on aerial imagery available from Google Earth (2022). As can be seen in the aerial imagery, four to five dead trees stand around the house in July 2019, and in June 2021, aerial imagery shows these trees have been removed. The building stands derelict. 22 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 23. Site 5WL9413, Feature 4 (well/pumphouse) on left, Feature 1 (house) at center, and Feature 2 (garage/shed outbuilding) on right, view to the northeast. Feature 1 is a single -story brick house on an L-shaped footprint, with a late addition enclosing the front porch on the south fa�ade with a shed roof and wood cladding (Figures 24-27; see Figure 23). Weld County Assessor records indicate it was built in 1900 (Weld County 2022b). The house lacks a distinct style, borrowing elements from the time of its construction, including a square main mass with hipped roof, and most original window openings are crowned with a lintel of vertically set bricks with shaped Dakota sandstone windowsills. None of the windows in the brick walls appear to be original; all have added double sash window lites with added framing to center them in the opening. Only the enclosed wood front porch may have original six-lite casement windows (a connected row of three on front); however, the porch's side windows may also have been replaced. Each building fa�ade has one to three windows. The front door and porch are centered on the south fa�ade and the back door is centered in front of a (later addition) plank deck on the north elevation. The house appears to have a coal cellar opening on the western edge of the south fa�ade. The building sits either on a concrete foundation or on a stone or block foundation that is surfaced with cement. The hipped roof is currently and recently tiled with basic brown asphalt shingles, matching the adjacent outbuildings. The main north mass of the building has a square -hipped roof rising to a small square flat top. The south leg of the L-shaped house is rectangular and covered with a cross -hipped roof. A rear dormer, also hipped, is centered on the north side and serves as an attic vent. Plumbing vents made of recently added polyvinyl chloride pipes protrude from the west side of the roof. A propane tank on the east side of the house suggests propane heating. 23 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado r =L...22 iva' yC 1 yaw a 2�_ is •i Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado 34.0' First Floor 1357.7' 30.7' 44.-; ' 11.5' 14.0' 22.5' . • • 8.0' ; 1 12.0' ; • 14.0' Encl Solid Wall Figure 26.

Feature 2 is a wood -framed and wood -clad outbuilding, which may have served as a garage and shed, has horizontal lapboard siding that matches the front porch addition on the house (Figure 28; see Figures 23 and 27). The wood siding at both buildings is similar to and likely contemporaneous to the wood -framed farmhouse adjacent to it at 1519 East 8th Street (5 WL9412). The end -gabled rectangular garage building 25 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado has an end -gabled shed added on its east end. The outbuilding appears to have been converted to a two - bay garage, with the bay doors (currently off the building) made of plywood. Based on vertical siding placed between the two bays, this west end of the outbuilding may have been entirely open on the front (south side) before renovations in recent years. The attached shed has a separate two -door entry set on the west end of its south side. A nine-lite window is adjacent to the entry and centered in the south fa�ade of the shed. The east end of the shed has been reclad and repaired recently. The roof has also recently been reclad with brown asphalt shingles matching those of the house. The roof of the shed is asymmetrical, and more sloped at the rear (north side) of the building. Unlike the adjacent house, the shed and garage have exposed rafters at the eaves. Figure 28. Site 5WL9413, Feature 2 (garage/shed outbuilding), view to the north. Feature 3 is a small outhouse structure southeast of the garage/shed outbuilding (Figure 29). It is constructed the same as the garage/shed outbuilding, clad in horizontal wood siding (abutted rather than lapped or joined planks). In contrast, the off -center door, facing the farm complex, is made of vertical planks. The north fa�ade has a tiny square unglazed vent window centered in its upper portion. The shed roof on the outhouse appears to have been replaced. The outhouse is set over an open, oversized hole that appears to have been dug in recent years and the structure moved over it and, without deposition, would not have further archaeological potential. 26 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado Figure 29. Site 5WL9413, Feature 3 (outhouse), view to the southeast. Feature 4 is a well/pumphouse located southwest of the house (see Figure 23). It is covered in a front - gabled roof clad in brown asphalt tiles that are older and do not match the roofing material on the house and garage/shed outbuilding. The small structure's sides are covered in overlapping horizontal wood cladding that matches the enclosed porch on the house. It sits on a rectangular cement foundation. An undersized plywood door is centered on the south -facing fa�ade, under the gable of the roof Although the house and its outbuildings are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house and outbuildings have had incongruous changes and additions made to them, including the mismatched porch and replaced window openings on the house and changes/repairs to the siding and entry openings on the outbuildings. The property lacks significance and integrity under any NRHP criteria. CONCLUSIONS AND RECOMMENDATIONS Given the level of heavy agricultural use occurring on this parcel, confirmed by the reconnaissance survey, no native sediments that could have harbored precontact or early historic archaeological sites remain in the project area. Therefore, no additional archaeological assessment is recommended. The project area holds four historic farmsteads (5WL9410-5WL9413) with houses dating between 1900 to 1938; however, all buildings and structures have been heavily modified from their original historic look, do not represent masterful architectural works, and are not closely associated with notable historical figures. All the buildings and outbuildings lack significance and integrity under any NRHP or SRHP criteria. Therefore, SWCA recommends that 5 WL9410, 5 WL9411, 5 WL9412, and 5WL9413 are not 27 Cultural Resource Review aQd Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project, Greeley, Weld County, Colorado eligible for the NRHP or the SRHP and that no historic properties will be affected by the development of the Fairmeadows RV Stowage and Gravel Mining Pit Project. No additional work related to historic architectural resources is recommended. 28 Cultural Resource Review and Reconnaissance Survey for the Fairmeadows RV Storage and Gravel Mining Pit Project Greeley, Weld County, Colorado REFERENCES CITED Boyd, David 1890 A History: Greeley and the Union Colony.

The Weld County property assessment indicates that this house was built in 1905, and that date issupported based on the style of its original siding and framing apparent in the 2001 assessment photograph (Weld County 2022). However, its foundation appears to be a robust concrete that may have been added or replaced later; it is possible, but unknown whether the house was moved to the property at a later date. The rear addition is obviously from after the original construction of the house; its east-northeast extent appears to have allowed for the introduction of an indoor bathroom. The back steps are wood replacement steps; the front porch is weathered concrete with a newer concrete sidewalk curving OAHP Site #: 5WL9410 OAHP Form #1417 outward from it. Its siding has recently been replaced along with all windows and doors, a recurring trend for wood -framed houses on the property. The roof has been recently re -shingled in gray asphalt tiles, another recurring trend for houses on the property. Under the overhanging eaves of the roof, the exposed rafter ends are braced on the gable ends of the house. 14.

Based on Weld County records; the house was built in 1938, the same year as the house at 1519:East 8th Street (5WL9412), which is consistent with its construction style: Overall, the building has had additions through time, including a shed roof extension of .the back (north) and a shed -roofed entry room on the northeast corner.. The main, original house has a cross -gabled roof, and the original footprint would have been T-shaped. The eaves are enclosed: with no rafters exposed. Roof shingles are new gray asphalt tiles. Like the house discussed_ previously (1507 East t 8th Street/5WL9410), it is apparent from Weld County Assessor photographsfrom 2001 that earlier horizontal wood siding on this OAHP Site #: 5WL9411 OAHP Form #1417 house has been replaced.

Feature 1 is currently the only occupied residence in the series. of houses on the project property. Based on Weld County records, the house was built in 1938, and its construction is consistent with that assessment: The house at 1515 East 8th Street (5WL9411) was also built in 1938. The house is now on an L-shaped footprint but appears to originally have been built OAHP Site #: 5WL9412 OAHP Form #1417 rectangularly. An entryway wing on the southeast corner appears to be a later addition, as does a westward extension on the front of the main body of the house. The horizontal wood siding on the exterior walls appears to have been replaced throughout the building. The front (south) windows have all been replaced with more recent casement windows, whereas the side and rear facades retain double sash wood -framed windows. The roof is hipped on the east side, front -gabled over the entry wing, and end - gabled over the west facade. Roof shingles are new gray asphalt; however, the adjacent garage (Feature 2) has older wood singles. A single brick chimney is centered on the roof. The eaves have exposed rafters. The foundation and porches are concrete. A crawl space opening is apparent at the front of the building. The door at the original front entry appears to be a recent replacement, although the door in the added entry wing appears to be older and original. 14.

Feature 1 is a single -story brick house :on an L-shaped footprint, with a late addition enclosing the front porch on the south facade with a shed roof and:Wood cladding. Weld County Assessor records:indicate: it was built in 1900 (Weld County 2522).:The house lacks a distinct style, borrowing elements from the time of its construction, including a square:main mass with hipped roof, and most original window openings are crowned with a lintel of vertically set bricks With shaped Dakota sandstone windowsills. None of the windows•in the brick: walls appear to be original; all have:added double sash -window lites with added framing to center them • • in the opening: Only the ericlosed,wood front porch may have original six-lite casement windows (a connected row of three on OAHP Site #: 5WL9413 OAHP Form #1417 front); however, the porch's side windows may also have been replaced. Each building fa�ade has one to three windows. The front door and porch are centered on the south fa�ade and the back door is centered in front of a (later addition) plank deck on the north elevation. The house appears to have a coal cellar opening on the western edge of the south facade. The building sits either on a concrete foundation or on a stone or block foundation that is surfaced with cement. The hipped roof is currently and recently tiled with basic brown asphalt shingles, matching the adjacent outbuildings. The main north mass of the building has a square - hipped roof rising to a small square flat top. The south leg of the L-shaped house is rectangular and covered with a cross -hipped roof. A rear dormer, also hipped, is centered on the north side and serves as an attic vent. Plumbing vents made of recently added polyvinyl chloride pipes protrude from the west side of the roof. A propane tank on the east side of the house suggests propane heating. 14.

Notes: Although the house and its outbuildings are on a property owned by a Union Colonist and early Greeley settler Joel Edwin Davis, he acquired this property later in life as an investment rather than it being directly tied to the family's historical prominence in the region. The property has remained investment/rental property ever since. The house does not present significant or masterful architectural elements of design or materials. The house and outbuildings have had incongruous changes and additions made to them, including the mismatched porch and replaced window openings on the house and changes/repairs to the siding and entry openings on the outbuildings. The property lacks significance and integrity under any NRHP criteria. 22. Sources: Weld County 2022 Weld County Property Portal: Available at: https://propertyreport.co.weld.co.us/?account=R2581503.
