Glendora's foothill-community history and the Village's evolution
Glendora was founded in 1887 as a citrus-growing community in the foothills of the San Gabriel Mountains, taking advantage of the substantial water resources flowing out of the mountain canyons and the protected foothill climate that produced excellent citrus growing conditions. The original town site was platted along what is now Glendora Avenue, with the commercial district developing during the late 19th and early 20th centuries to serve the growing citrus-grove operations and the residential community that developed around them.
Route 66 was routed along Foothill Boulevard through Glendora in 1926, immediately adjacent to but distinct from the Village's commercial core on Glendora Avenue one block north. The Route 66 designation brought substantial commercial development to Foothill Boulevard during the 1930s-1950s — gas stations, motels, restaurants, and the typical Route 66 highway-service businesses — while the older Glendora Village district continued operating as the more community-oriented commercial core for Glendora residents themselves.
The post-WWII suburban development that transformed most of the eastern San Gabriel Valley into chain-store-dominated commercial sprawl largely bypassed the core Glendora Village district. Community-supported zoning, the small parcel sizes of the historic Village commercial buildings (which were unsuitable for big-box chain development), and substantial sustained community engagement with downtown preservation produced a Village district that has maintained its independent-business commercial character into the present era — substantially distinct from the surrounding strip-mall sprawl that defines most of the I-210 corridor.
