The Rock Island City Council will vote Monday on a proposed 2 percent raise for city manager Thomas Thomas and a lump sum payment to his retirement account.

The raise was stipulated in his employment agreement when he was hired in 2011, Mayor Dennis Pauley said. Mr. Thomas's salary will increase from $140,000 to $142,800 after the raise.

The lump sum payment to Mr. Thomas's account with the International City Management Association Retirement Corporation deferred compensation program will amount to 5 percent of his salary, or $7,140.

Mayor Pauley said the lump sum payment was not in Mr. Thomas's employment agreement but has been recommended because other city department heads annually receive the payment.

Also at Monday's meeting, the council is expected to vote on a proposal to delay implementing a requirement that new single and double family homes include a sprinkler system.The requirement was to be implemented Jan. 1, 2013, but city officials now recommend the start date be delayed until Aug. 1.

Milan and Rock Island County have adopted the residential sprinkler requirement, a regulation backers say will make homes safer. Bettendorf also adopted the requirement, but aldermen there have moved to delay its implementation until August, as proposed in Rock Island.

New building codes include the residential sprinkler requirement. Developers who oppose the regulation say it will make new homes less affordable.The Quad Cities Home Builders Association is among the opponents of mandatory sprinkler requirements for residential homes.

During a study session before Monday's Rock Island City Council meeting, the sprinkler requirement is scheduled to be discussed. The study session also is scheduled to include discussion on a proposed "loitering ordinance" for The District.

The council is considering rules to keep youths younger than 21 from loitering in The District late at night because of complaints from some business owners.
