</ref> As a result, Chalmette was extensively swamped and destroyed. A majority of the population evacuated shortly before the storm hit, but there was still significant loss of life.

As of October 25, 2005, most of the buildings were deemed unsalvageable. Despite findings published by the U.S. [[United States Environmental Protection Agency|EPA]], the toxic chemicals in the water from local oil refineries have been postulated to be an ongoing health hazard by several civilian ecological groups. Especially notable was the large [[oil spill]] originating in Chalmette's [[Murphy Oil]] facility, where the storm surge knocked over a huge oil tank (''see photo below'').<ref name="Meiners">{{cite news |last1=Meiners |first1=Joan |last2=The Times-Picayune |last3=The Advocate |title=How Oil Companies Avoided Environmental Accountability After 10.8 Million Gallons Spilled |url=https://www.propublica.org/article/how-oil-companies-avoided-environmental-accountability-after-10.8-million-gallons-spilled |access-date=December 29, 2019 |work=ProPublica |date=December 27, 2019}}</ref>

{{nowrap|The parish administrative}} headquarters served as the site for a [[Federal Emergency Management Agency]] (FEMA) [[trailer park]] for numerous civil servants who were laboring in the rebuilding effort. A year later, parish employees were still working shifts around the clock to bring the community back to life.

Another center in the rebuilding effort was centered at the church of Our Lady of Prompt Succor, which served the congregations of the seven other Roman Catholic parishes as well as the main office of [[Catholic Relief Services]]. It also served as the only place to hold funerals for the first 12 months after Katrina.

Deputies working for the St. Bernard Parish Sheriff stated in early December 2005 that the oil tank floated in the flood. When the water receded, the tank settled on uneven ground. Its structural integrity was compromised, and then the oil spill occurred. By late November, the Murphy facility was functional, as was a small cluster of businesses around the intersection of Paris Road and St. Bernard Highway, on the least damaged River side of Chalmette. The devastated residential areas farther away from the River were open during daylight hours, for residents to salvage belongings from their damaged homes. The majority of people staying in Chalmette full-time were living in trailers, which began to be supplied by FEMA or private enterprises on October 12; although many who had been promised [[FEMA trailer]] housing were still waiting as late as March 2006, seven months after the hurricane.

"Camp Premier," renamed "Camp Hope," was established as a base camp for the community's rebuilding efforts, facilitating the work of relief organizations, the National Guard, and private individuals. As of August 2007, the camp is located at P.G.T. Beauregard Middle School and operated by [[Habitat for Humanity]], to provide for relief volunteers in St. Bernard Parish. Other organizations, such as the [[SBP (nonprofit organization)|St. Bernard Project]], have also participated in the rebuilding of Chalmette, from distributing supplies, to clearing debris, to repairing damaged houses.

The Chalmette Battlefield was also partially flooded in low-lying areas, destroying the visitor center, which has since been rebuilt.
