In spring of 2018, PMA completed a Reconnaissance Level Survey (RLS) of the Laurelhurst neighborhood in Portland, Oregon. Over 1,800 properties were surveyed. Data from the survey was used to prepare a historic district nomination of the neighborhood. A great deal of research was necessary to understand Laurelhurst’s general historical context prior to beginning survey fieldwork involved in the RLS. We began by reviewing all previous documentation that has been collected of the neighborhood—including historic tax and permit records, Sanborn maps and other graphic data, articles from historic newspapers and periodicals, and the City of Portland’s Historic Resource Inventory. We also reviewed context statements that had been written for earlier historic district nomination efforts, and primary source documents that had recorded Laurelhurst during its early stages of development.
Founded in 1909-1910 on what had been William Ladd’s Hazel Fern Farm, Laurelhurst was developed to be a combination of pastoral English “garden suburbs” close to the city, with a more formal Beaux-Arts radial layout. An eclectic variety of architectural styles, from “fairyland” bungalows to quaint English cottages to the more classic Dutch Colonials, was chosen as a set of prototype designs for the creation of this Streetcar-era, community-centered neighborhood. To this day, most of these homes still exist and create a pleasing variation of historic styles predominantly from the 1910s to the 1930s along the pedestrian-friendly public streets and sidewalks.

Buildings constructed before 1965 have reached the age of eligibility for being considered historic by the standards of the National Register. That means that much of Modern Architecture, the general period ranging from 1950 through 1970, is historic, or soon will be considered historic as the 50-year mark is crossed. As historians assess and study Modern Architecture, we provide ever more precise descriptions and terms to describe the sub-styles and variations within the large umbrella term, “Modern.” As in taxonomy, which classifies and categorizes living organisms, we can recognize and assign groups of similar resources together for study. 
The Olympia survey classified the first grouping of styles as those that are transitional. Transitional Modern styles have some elements of Modern and some elements of more traditional architecture. Windows might be vertically-oriented, double-hung wood windows (traditional) rather than having horizontal proportions (Modern). A roof might be a moderate pitch, with minimal overhangs (traditional), rather than a shallow pitch with outwardly-extending gables (Modern). In Olympia, 37% of the houses surveyed were Modern Minimal Traditional, by far the most prevalent Transitional Modern style. 
Ranch style architecture is the style that architecture critics have generally spurned, since houses were often constructed by contractors without architect’s involvement. Ranch buildings are broad, one-story, and horizontal in overall proportion. They have an attached garage which faces the street and is part of the overall form of the house, and almost always a large picture window facing the street as well. Cladding is used to accentuate the horizontal lines of the house, so there is often a change in material at the lower part of the front façade- brick veneer was a popular choice. Many of the sub-styles of Ranch architecture are “styled” Ranch houses, meaning that elements from another style of architecture were placed on a Ranch form building. One example is Storybook Ranch, which uses “gingerbread” trim, dormers or a cross-gable, and sometimes diamond-pane windows. Are these decorated sub-styles still part of the canon of Modern Architecture? In many ways, they are more Post-Modern than Modern, but that distinction is worthy of an involved discussion of its own. 
The Olympia Mid-Century Residential survey found over half the resources surveyed to be Ranch or variants of Ranch style. 31% of the surveyed homes were identified as simply Ranch, with another 11% Early Ranch, 9% Contemporary Ranch, 4% Split-Level or Split-Entry, and 4% one of the “Styled” Ranch variations. Sheer numbers alone remind us that the Ranch is deserving of study and shows us how the majority of middle-class Americans lived. As Alan Hess writes in his book Ranch House,

Many of Portland’s iconic landmark buildings are modern era resources, such as the Veterans Memorial Coliseum, Lloyd Center Mall, U.S. Bancorp tower, and the Portland Building. The survey intentionally excludes these well-known properties in order to highlight broader architectural patterns and identify some of the less prominent buildings that may be considered historically significant in the future.
Of approximately 976 modern period resources within the Central City’s seven geographic clusters, PMA selected 152 properties for reconnaissance level survey. Representation of geographic clusters, resource typologies, and potential eligibility were considered when selecting properties to survey. In a selective survey, most properties should be considered potentially eligible for historic designation. Online maps, tax assessor information, and Google Earth were used to inform the selection process. Fieldwork involved taking photographs of each property, recording the resource type, cladding materials, style, height, plan type, and auxiliary resources, and then making a preliminary determination of National Register eligibility based on age, integrity, and historic character-defining features. A final report outlines the project and findings, and survey data was added to the Oregon Historic Sites database.
