Its north end is at the intersection of Atlantic Avenue and Conduit Avenue. The south end is Exit 15 off the Belt Parkway. The area is mostly composed of landfill and has areas of swampland-like forest growth where improvements are contemplated.
At its north end, Fountain Avenue is just a side street, carrying one lane of southbound traffic only. Between Sutter Avenue and Linden Boulevard, Fountain Avenue is a six-lane, undivided roadway. South of Linden Boulevard, the avenue gains a median. South of Flatlands Avenue, Fountain Avenue continues through past Seaview Avenue, where it curves under the Belt Parkway. The publicly accessible portion of Fountain Avenue ends just south of the Belt Parkway, at the site of the former Fountain Avenue Landfill. The Fountain Avenue Landfill was later developed for public use as part of Spring Creek Park.
Various tests of the Fountain Avenue area and landfills were conducted in 1985 and 1986.
A December 4, 1998 press announcement by Congressman Vito Fossella stated that Fossella "laid out a compelling argument for deauthorizing the property as part of Gateway National Recreation Area and restoring it as a temporary waste disposal site only for trash generated in Brooklyn".
Bill Farrell, writing for the New York Daily News, summarized the condition of the area during a 2003 article: "The malodorous, toxic and visual nightmare reviled by drivers along the Belt Parkway will soon be transformed into 400 acres (1.6 km2) of parkland along Jamaica Bay."
BergerWorld reported in its 2nd Quarter 2006 report: "Berger, teamed with URS, is assisting the New York City Department of Environmental Protection in the $160 million, 297-acre (1.20 km2) Pennsylvania & Fountain Avenue Landfills (PAFAL) closure project in Brooklyn, NY, one of the largest closures ever undertaken in the state of New York"
The landfill was mentioned on July 10, 2007 as undergoing a $20 million ecological restoration with the Pennsylvania landfill. The area is also under discussion by local government to be considered for more development. City Line Park was mentioned as being redesigned and transformed under a $1.5 million renovation launched this day.
Ecological concerns were later expressed for the area on a "New York Habitat Restoration" webpage.
Fountain Avenue has been infamous as a dumping ground for bodies of people slain by the mob. In the 1930s a group known as Murder, Inc. used the area as a dumping ground for bodies. Later the DeMeo crew disposed of many victims there. In 2006, the body of Imette St. Guillen, who was murdered on February 25, was discovered.
