HARRISBURG — As the public’s turn to comment on the redrawing of Pennsylvania’s legislative districts expired Wednesday, two Republicans on the panel in charge of the process declined to speculate about any revisions to the maps that will shape the General Assembly for the next decade.

House Majority Leader Mike Turzai said he anticipates “some refinements” based on points raised during two days of public hearings before the panel votes on a final plan, which he said he expects will take place Dec. 12.

“We are all going to review that input,” the Allegheny County lawmaker said Tuesday, adding that the panel will “incorporate that which we think has merit.”

Senate Majority Leader Dominic Pileggi of Delaware County said there was no consensus on specific changes among the five members of the Legislative Reapportionment Commission. While he allowed that “there’s always room for improvement,” he said he also could envision the plan being adopted without any further revisions.

The constitutionally mandated commission — consisting of the Republican and Democratic floor leaders in the two chambers and a judge appointed by the state Supreme Court who serves as chairman — split along party lines when it adopted the preliminary plan in October. Chairman Stephen J. McEwen Jr., president judge emeritus of the state Superior Court and a Republican, cast a tie-breaking vote to adopt the GOP proposal as the preliminary plan.

At the November hearings, dozens of people from across the state registered wide-ranging complaints about the planned reconfiguring of the 50 Senate districts and 203 House districts to reflect population shifts evident in the 2010 census. Their concerns included gerrymandering to protect incumbent legislators and parties, splitting dozens of communities into multiple House districts and the relocation of one Senate district from the state’s southwest corner to its northeast corner.

Barry Kauffman, director of Pennsylvania Common Cause, blamed political considerations for what he considers an excessive number of municipalities being split up among different legislative districts. He noted the state constitution says no county, city, borough, township or ward should be divided “unless absolutely necessary.”

“The constitution doesn’t just say try” to keep communities intact, said Kauffman, whose group has urged the reapportionment process be turned over to an independent panel.

The commission has until Dec. 30 to approve a final plan. But the panel is under pressure to end the uncertainty over the district boundaries soon so prospective candidates for the Legislature and Congress can make informed decisions about their political futures.

Under state law, candidates will have three weeks beginning Jan. 24 to gather enough petition signatures to qualify for the 2012 ballot. But the state constitution allows appeals of a final legislative redistricting plan to be filed for 30 days after it is approved — pushing that period into January.

Negotiations over the separate process of congressional redistricting, which is complicated by the loss of a seat that will reduce the state’s U.S. House delegation from 19 to 18, are continuing behind the scenes in the Legislature.
