CRANBERRY TWP — Changes in the General Assembly maps will lead to new representatives for some Butler County residents and some office-seekers running in other districts — if at all.

New maps for the state House of Representatives and Senate, approved Friday by the Legislative Reapportionment Commission, differ from the December preliminary plan, as well as from the districts in which Pennsylvanians have lived for the past decade.

State House District 8, which in the December plan would have been without an incumbent as no current representative lives in that proposed district, will officially include much of western Butler County, as well as part of Lawrence County.

While Slippery Rock was in the proposed 8th District, it will now be in District 17 along with southern Mercer County, a district in which incumbent state Rep. Tim Bonner, R-8th, lives.

Slippery Rock Mayor Jondavid Longo, who announced he would run for the 8th District should the December proposal have held, said Bonner’s residence in the district means he will not run for the state House.

"In my original announcement, I said that if the proposed maps should hold I would run for District 8, but if not I would gladly support the incumbent, so I will be supporting the incumbents in my general vicinity,“ Longo said. "I will gladly be supporting the incumbent state reps in our area, and I look forward to working with Rep. Bonner as our state representative."

In southwest Butler County, changes between the proposed and adopted state House districts moved one candidate from one district to another.

Gregg Semel, a Zelienople councilman who originally announced he would run for the District 8 seat, said Monday he is still running, just now for the 12th District, which includes Zelienople.

The new 12th District, which is geographically smaller from the prior version due to population growth, will now include Adams, Cranberry and Jackson townships, as well as Callery, Evans City, Harmony, Mars, Seven Fields, Valencia and Zelienople, eschewing some of its former territory.

Clinton Township will now be in the 11th District, which includes much of eastern Butler County plus Butler. Former 12th District territories Forward, Middlesex and Penn townships will also be included in the 8th District.

The 41st senatorial district will no longer include eastern Butler County, leaving just the 21st and 47th districts to represent the county in the upper chamber.

With the realignment in Butler County — state Sen. Joe Pittman, R-41st, will lose that seat — the remaining districts will include new areas to make up for the shift.

State Sen. Scott Hutchinson’s, R-21st, district will now include all of Butler County north of Lancaster Township and east of Middlesex Township, as well as Butler, Connoquenessing and Penn townships and Butler City.

The 47th District, represented by Republican state Sen. Elder Vogel, will now include Cranberry, Forward and Middlesex townships, plus Callery, Evans City, Mars, Seven Fields and Valencia.

Vogel’s district will also include Harmony, Jackson Township and Zelienople, which remain from the current 47th District.
