The Glenwood-Wilbur Street Historic District is found within the original Mesa town site limits and is composed of three residential subdivisions platted between 1912 and 1922.
- Wilbur Subdivision (platted 1912)
- Glenwood Tract (platted 1920)
- W. R. Stewart Subdivision (platted1922)
These subdivisions were developed by reconfiguring existing blocks from the original townsite plat. The district serves as an excellent example of Mesa's transition from a pastoral, agricultural community to a more urbanized city, mirroring the growth of neighboring cities like Phoenix, Glendale, and Tempe. By 1922, 27 of the original large lots had been subdivided into smaller parcels to accommodate the increasing demand for housing.
The district, primarily composed of residential buildings, exhibits two distinct character zones based on street width. The wider streets of Hibbert and Pomeroy, part of the original townsite, maintain a more open feel, while the narrower streets of Pasadena and Wilbur convey a more urban atmosphere.
Despite some modern intrusions, the district retains its original residential character. It is surrounded by some vacant land and larger-scale modern developments, such as the Mesa Conference Center, a major arts and convention complex located just to the west of the district.
