What is County Council?
As referenced from the Allegheny County website:
"Allegheny County Council is the legislative branch of our county government. The council is made up of fifteen elected officials – thirteen district representatives and two at-large (county-wide) members. Members are elected for staggered four-year terms.
Powers and duties of the council include: approving and amending legislation submitted by either the County Executive or a Council member, annually adopting a balanced county budget, permitting use of county land, levying taxes and fees, and confirming or rejecting appointments for county agencies and authorities."
