<br />*P3a. Description (continued):
<br />Secondary façades on the north, south, and east, including the rear addition completed circa 2012, are consistent with the
<br />general characteristics of the front-facing west façade, including multi-pane hung, fixed, and casement windows of both wood
<br />and vinyl sashes; glazed wood doors; and clay ornamental features, specifically false canales (Figure 5). A non-historic
<br />stuccoed privacy wall along the north property line wall encloses the side and back yards. On the north elevation, near the
<br />front of the residence, is the stuccoed chimney, featuring a molded stucco triangle feature (Figure 6). Facing the side yard is
<br />one of three secondary entrances, which features a small porch, ten-light French doors, and historic wood hung windows with
<br />six-light upper and single-pane lower sashes (Figure 7). The porch, which occupies a recess in the north elevation is
<br />sheltered by exposed beams emanating from the exterior wall. The other entrances are located on the east elevation of the
<br />original rear of the residence and north elevation of the addition and feature glazed wood doors. Both entrances area
<br />accessed by short sets of steps with roughly identical stuccoed curved balustrades topped with tile coping (Figure 8).
<br />Windows on the historic sections of the secondary elevations are uniformly wood-sash units, with configurations that include
<br />multi-light fixed, hung with multi-light upper and fixed lower sashes, and multi-light casements. Windows throughout the rear
<br />addition feature vinyl sashes and are configured to complement the historic character of the house with vertically sliding
<br />operability, multi-pane sashes, and elements suggesting ogee lugs.
<br />Situated at the far eastern end of the parcel, the detached garage was constructed in 2012 to complement the historic
<br />appearance of the property (Figure 9). It is rectangular in plan, sheathed in stucco, and capped with a flat roof concealed by
<br />a minimally shaped parapet with tile coping. The roll-up garage door faces a short driveway to the north, accessing
<br />Edgewood Road. The property is landscaped with a front lawn, low shrubs, mature ornamental trees, and various flowering
<br />plants.
<br />*B10. Significance (continued):
<br />The Mills House is located in the Park Santiago neighborhood. The neighborhood is bounded by Santiago Creek and Park on
<br />the north, East Seventeenth Street on the south, North Lincoln Avenue on the east, North Main Street on the west, and the I-
<br />5 freeway on the southwest. In large part these boundaries reflect the transportation lines that were constructed towards the
<br />end of the nineteenth century and at the beginning of the twentieth century, when the Pacific Electric interurban railroad ran
<br />up Main Street; the Atchison, Topeka, and Santa Fe tracks followed Lincoln; and the Southern Pacific Railroad right-of-way
<br />mirrored the freeway route.
<br />This area remained primarily agricultural well into the 1920s. As of 1905, the city directories listed around twenty households
<br />on East Santa Clara, Twentieth Street, “C Street” (now North Santiago Street), North Bush Street and North Main Avenue,
<br />the only streets in the area at the time. The vast majority of the residents were ranchers. By 1911, the number of households
<br />had increased to about thirty, and Edgewood Road and Valencia Street had been partially laid out, but most residents
<br />continued to list “rancher” or “fruit grower” as their occupation in the city directories. This pattern of land use was evident on
<br />the 1912 plat map of the City, which illustrated two small, Craftsman era subdivisions along Bush north of Santa Clara and on
<br />Valencia and Poinsettia south of Twentieth Street, with the remaining area divided into larger, agricultural parcels held by
<br />approximately forty landowners.
<br />While the area east of Santiago Street was not subdivided until after the mid-1920s, most of the present day streets west of
<br />Santiago had been laid out when the City was mapped in 1923. Ranching continued to be the most prevalent occupation in
<br />the neighborhood, but increasing numbers of professionals, small business owners, merchants, and people in service
<br />professions such as painters, electricians, and carpenters made their homes in the western half of the neighborhood during
<br />the 1920s and 1930s. The area also attracted several city and county officials, including the City Attorney (Z. B. West, Jr.,
<br />321 East Santa Clara Avenue), County Supervisor, First District (C. H. Chapman, 2315 North Santiago Street), County
<br />Surveyor (E. H. Irwin, 2407 North Santiago Street), and County Auditor (William C. Jerome, 2422 Poinsettia Street). By April
<br />1942, when the Sanborn Company first mapped the western half of the area, most of the lots had been improved with single-
<br />family homes, many in the revival styles popular during the 1920s and 1930s. Subsequent development of the eastern half of
<br />the neighborhood and infill construction in the western half displayed the simplified ranch style that emerged following World
<br />War II.
<br />
<br />The Mills House qualifies for listing in the Santa Ana Register of Historical Properties under Criterion 1 as an intact example
<br />of a Spanish Colonial Revival-style home in Santa Ana. Located in Park Santiago, the house was constructed in 1925. The
<br />recommended categorization is “Contributive” because it contributes to the overall character and history of its neighborhood
<br />and is a good example of period architecture (Santa Ana Municipal Code, Section 30-2.3). Character-defining features of the
<br />Spanish Colonial Revival style exhibited by the house include, but are not necessarily limited to, its asymmetrical wing-and-
<br />gable composition; clay-barrel-tile roofing; portico with pyramidal and arched openings; front patio with low, stuccoed privacy
<br />wall; side porch (north façade) with extended-beam shelter; wood-sash windows in various configurations; recessed,
<br />segmental-arch window surrounds on the primary façade; ornamental details including the clay gable vent, oeil de boeuf,
