With primary elections approaching, Rockville's mayor and City Council have sought to restrict political signs by setting limits on advertisements for candidates and issues.

Under the new law, anyone who wants to set up a political sign must register it with the city. Most signs cannot be put up until 45 days before the election, and losers must take down their signs within 10 days after the vote. Independents or winners of primary elections may keep their advertisements in place, as long as the general election follows within 75 days.

The new law also limits the size of signs, officials said. Signs in residential neighborhoods may be no larger than nine square feet. Political advertisements in other areas of the city must not exceed 32 square feet.

The council also awarded bids for supplies and equipment last week. A city firm, Fetco Inc., was hired for $38,000 to tear down the former Woolworth Building at the intersection of Washington Street and Middle Lane.

Rockville officials had been asked to make recommendations to the Montgomery County Council on how transfer development rights, known as TDRs, might affect Rockville, and how TDRs should figure in with area development plans. After a study by the city planning department, the council decided to send a letter to the County Council, saying, "the mayor and council do not believe there will be any effect by TDRs on the city's plans and programs, and thus has no recommendation."
