TOPEKA – A bill Gov. Kathleen Sebelius signed Tuesday will restrict signs and outdoor advertising for strip clubs, adult video stores and other sexually oriented businesses.

The billboard law is one of several strategies sex-shop opponents are using at the state and local level.

Under the new law, billboards for those businesses are prohibited within one mile of any state highway. Any adult business within a mile of a highway, as most are, is limited to two signs.

One, no bigger than 40 square feet, can display only the business name, address, telephone number and operating hours. The second sign, required under the law, must state that the property is off limits to minors.

Businesses that currently display larger signs will have three years to remove them.

Sex-shop opponents also are circulating petitions to convene grand juries to bring obscenity charges and are seeking zoning changes to keep the businesses out of the commercial mainstream.

In Wichita, a petition is expected to be presented this week. A similar effort last year resulted in a charge against one business for one video.

The bill is Senate Bill 35.
