Avondale is an unincorporated community in Prince George's County Maryland, United States. It is contained between Eastern Avenue NE to the south, Queens Chapel Road (MD-500) to the east, and the Northwest Branch Anacostia River to the north and west. Avondale borders the neighborhoods of Hyattsville, Chillum, Green Meadows, and Mount Rainier in Prince George's County, Maryland. In addition to these neighborhoods in Prince George's County, Avondale also borders the North Michigan Park neighborhood of Northeast Washington D.C. The Avondale neighborhood consists of three small subdivisions since being established: Avondale, Avondale Terrace, and North Avondale. For statistical purposes, Avondale is part of the Chillum census-designated place (CDP), even though Avondale is actually a completely separate neighborhood from Chillum. History The settlement of Avondale began in the late 1930s as a small residential subdivision at the intersection of Eastern Avenue and Queens Chapel Road. In the 1930s, area development spread west from Hyattsville, Mount Rainier, and Brentwood. Developers of the Avondale neighborhood promoted the area's very close proximity to Washington D.C. as well as its already established utility supplies. Construction of the Avondale Grove subdivision began in 1939. By 1942, the community contained approximately 100 structures located along eight streets on a wedge-shaped tract. At the southwest tip of the subdivision, Carson Circle, the community's entryway, forms a quarter-circle between the Avondale boundary streets of Queens Chapel Road and LaSalle Road. The interior roads of the subdivision radiate northward from Carson Circle. Along these streets are houses constructed in the 1940s and 1950s and included within subdivisions named Avondale Terrace and North Avondale. In the 1960s, the Avondale area along Queens Chapel Road was developed. Three high-density apartment complexes were constructed on Queens Chapel Road, Kings Park Plaza, Queens Park Plaza, and Avondale Overlook. The other apartment complexes in Avondale, such as La Salle Park, Avondale Park, and Manor Apartments, were developed shortly after. The Washington Metropolitan Area Green Line train tracks have gone through the community of Avondale when traveling between the West Hyattsville and Fort Totten Metro Stations, ever since the West Hyattsville Metro Station opened in December, 1993. The Washington Metropolitan Area Transit Agency (WMATA) originally had a plan to construct the "Chillum" Metro Station on Chillum Road in Avondale in 1955. WMATA scrapped that plan in 1978 due to strong opposition from many residents living in the Avondale Chillum neighborhoods and in the Kirkwood Apartments in Hyattsville.
