Final answer:
The Joel Health and Dental Clinic was opened in Benin, West Africa in 2013 by the US Army Corp of Engineers, following an initiative by the Kaiser Foundation in 2012 to develop the previously vacant lot.
Step-by-step explanation:
The Joel Health and Dental Clinic was opened by the US Army Corp of Engineers in the country of Benin, West Africa in 2013. This facility was designed to serve the community with various health services, including waiting, consultation, observation, treatment rooms, and a drug store. Prior to the clinic's establishment, the site where the clinic now stands was a massive vacant lot that had remained empty for several decades. In 2012, the Kaiser Foundation, known for its contributions to healthcare, initiated a project to develop this empty space into a facility beneficial to the community, which resulted in the opening of the clinic the following year.
