Editing Arcadia, California (section)

===20th century until World War II===
By the turn of the 20th century, Arcadia had a population nearing 500 and an economy that was coming to be based on entertainment, sporting, hospitality, and gambling opportunities, the latter including an early version of the Santa Anita race track.<ref name="history"/> Baldwin oversaw the incorporation of Arcadia into a city in 1903, and was its first mayor.

====Anoakia====

In 1913 Anita Baldwin, Lucky's daughter, built a 50-room mansion on {{convert|19|acre|m2}} of the Baldwin Ranch she inherited from him, and named it "Anoakia" (a [[portmanteau]] of Anita and oak).<ref name=arcadian>Rochlin, Michael Jacob; "Arcadian L.A."; {{ISBN|0-9648304-8-5}}; published by Unreinforced Masonry Studio; 2003. pp.38–111; photographs, house and estate plans, history.</ref> The {{convert|17,000|sqft|m2|adj=on}} residence was in the Italian [[Renaissance Revival architecture|Renaissance Revival style]], with murals by [[Maynard Dixon]].<ref name=arcadian/><ref name=latimes>{{cite web|url=https://www.latimes.com/archives/la-xpm-1999-dec-21-me-46205-story.html|website=Los Angeles Times|title=Arcadia Council to Decide Future of Founding Family's Historic Mansion|date=December 21, 1999|author-last1=Winton|author-first1=Richard}}</ref><ref name=timesplans>{{cite web|url=https://www.latimes.com/archives/la-xpm-1990-06-28-ga-953-story.html|website=Los Angeles Times|title=Plans for Development Force School From Idyllic Campus|date=June 28, 1990|author-first1=Siok-Hian|author-last1=Tay Kelley}}</ref> The estate had a significant [[Greek Revival architecture|Greek Revival-style]] [[colonnade]]d "Parthenon" bathhouse/gymnasium beside a large pool, an apiary and aviaries, kennels and stables, tennis courts and pergolas, and preserved the native [[California oak woodland|oak woodland]]s.<ref name=arcadian/>

After her death in 1939 the estate became the Anoakia School for Girls, which became the coeducational Anoakia School in 1967, then moved to Duarte in 1990 as the Anita Oaks School.<ref name=timesplans/><ref>{{cite web|url=http://www.education.com/schoolfinder/us/california/duarte/anita-oaks-school/|title=Anita Oaks School|work=education.com|access-date=June 3, 2015}}</ref> The school owner's efforts to develop the property into a village of homes with the old mansion as its centerpiece were rejected by the city.<ref name=latimes/> After an extended debate, with local citizens and regional [[Historic preservation|preservationist]]s efforts to preserve the historic main house, the city council voted to approve demolition for a real estate development by new owners in 1999.<ref name=latimes/> The "Anoakia" mansion, all other significant estate structures and outbuildings, garden features, and numerous [[Platanus racemosa|California sycamore]] and [[Quercus agrifolia|Coast live oak tree]]s were demolished for 31 luxury home sites in 2000.<ref name=arcadian/> Some of the mansion's architectural elements were salvaged and removed. The gatehouse, on the estate's former southeast corner at Foothill and Baldwin, and the perimeter walls remain after the "Anoakia Estates" development was built.<ref name=arcadian/> The bas-relief fountain was moved to just inside the new gated entrance.

====Inter-war decades====

During [[World War I]], Arcadia was home to the U.S. Army's [[Ross Field (airfield)|Ross Field]] Balloon School, at the present-day Santa Anita Park site. Army observers were trained here in techniques to observe enemy activity from [[hot air balloon]]s.

After World War I, Arcadia's population grew and local businesses included many chicken ranches and other agricultural activities. During the 1920s and 1930s, Arcadia began its transition to the residential city that it is today, as small farms and chicken ranches gave way to homes and numerous civic improvements, including a city library and a city hall. Scenes of many of Arcadia's interesting older sites can be viewed in a series of historic watercolors painted by local artists Edna Lenz and Justine Wishek.<ref>{{cite web |url=http://library.ci.arcadia.ca.us/dbtw-wpd/queries/arcPAINTquery.htm |title=Edna Lenz and Justine Wishek Paintings |publisher=Library.ci.arcadia.ca.us |access-date=January 24, 2011 |archive-url=https://web.archive.org/web/20130729234233/http://library.ci.arcadia.ca.us/dbtw-wpd/queries/arcPAINTquery.htm |archive-date=July 29, 2013 |url-status=dead  }}</ref> The city was on historic [[U.S. Route 66 in California|U.S. Route 66]], present-day [[Colorado Boulevard]], with businesses serving travelers on it.

[[Thoroughbred horse racing]] had flourished briefly under Lucky Baldwin, who founded a racetrack adjacent to the present site, until it was outlawed by the state of California in 1909. It returned to Arcadia when racing was legalized again, with the opening of [[Santa Anita Park]] in December 1934. Architect [[Gordon Kaufmann]] designed its various buildings in a combination of [[Colonial Revival architecture|Colonial Revival]] and [[Streamline Moderne]] styles.
