Claim: Cleveland Park station was part of the initial system plan in 1959, in 2016, a heavy rainstorm produced flash flooding, with the Porter Street entrance becoming flooded.
Evidence: While Cleveland Park was part of the initial system plan in 1959, the station opened on December 5, 1981, five years after the first segment began operations. On June 21, 2016, a heavy rainstorm with as much as 4 inches of rain per hour at times produced flash flooding with a southerly flow along Connecticut Avenue. The north-facing Porter street entrance was flooded, with water cascading down both the stairs and escalator for over 11 minutes.
