|The Wildwood Park Historic District is eligible for the National Register as an intact example of an early automobile suburb, with interrelated and associated residential subdivision and parkway. Using the criteria for the National Register, as described in the National Register Bulletin Historic Residential Suburbs: Guidelines for Evaluation and Documentation for the National Register of Historic Places, the Wildwood Park Historic District is eligible under Criteria (A) and (C). Under Criterion (A), it is significant as an outstanding example of a residential suburban development that introduced important trends and design principles locally and state-wide, and was particularly influential as a prototype for subsequent design in Northeastern Indiana, as it introduced naturalistic, curvilinear design and an architectural control committee. It also reflects the work of community builder Lee J. Ninde, a nationally and regionally significant master proponent of city planning, and the developer of several significant residential suburbs in northeastern Indiana . The Wildwood Park Historic District is significant under Criterion (C) as an outstanding example of a suburban development that reflects principles of design important in the history of community planning and landscape architecture, and is a significant example state-wide of the work of Arthur A Shurcliff, a nationally significant master landscape architect, and city planner. The Wildwood Park Historic District is also significant under Criterion (C) as an outstanding example state-wide of a subdivision which, through the significant expertise of Arthur Shurcliff, embodies high artistic values through its overall plan and the design of entrance ways, streets, homes, view-sheds, and community spaces. It is also locally significant under (C) as an example of a suburban subdivision. The Wildwood Park Historic District also possesses state-wide significance under Criterion C as an outstanding collection of residential architecture and is an important example of the distinctive period of construction, and the work of one or more notable architects.
