SACRAMENTO (CBS13) — The newly built water vault at McKinley Park was filled by Sunday’s storm, causing flooding of some streets nearby.

With Sacramento having a combined sewer system, big storms can often cause storm and wastewater to overflow into the street. However, the 6 million gallon vault built under McKinley Park is supposed to help prevent such events.
