I've put the owner as the city, and the operator as Madison Park Improvement Association (they adopted it in 2017 according to this https://web.archive.org/web/20170621062925/http://static.baltimorehousing.org/pdf/adopt_properties.pdf)

On the Madison Park Improvement Association's website and social media pages, they also use the names "1420 Eutaw Park" and "Mounds Park" to describe it; I am putting these as alt names for now but I don't know how the primary name of the three would be determined
