DENVER -- Large signs with pictures of an aborted fetus are nothing new in public areas and they're not new to homes of doctors or even staffers of abortion clinics.

But protests on residential streets where a construction worker lives are new.

The Greenwood Village enclave of Green Oaks is filled with large, custom-built million-dollar homes. And, for two months now, its quiet residential streets have also been filled with as many as 25 anti-abortion protesters.

Their goal is to discourage Bill Hornaday, an executive with Weitz Corp., from finishing work on a new Planned Parenthood headquarters miles away in Denver, near 38th Avenue and Quebec Street.

"This is ridiculous," said Hornady's neighbor.

"There is no end to what they'll do. This is not really about abortion. It's not about free speech. It's about intimidation. It's about harassment," said a resident, who wished to remain anonymous.

He is the father of two kids, ages 16 and 19.

The 16-year-old boy told 7NEWS he hides in the basement when he sees the van, covered in anti-abortion posters, go through the neighborhood, about four times a week.

The teen said he's scared when he sees a van sitting in front of the home before sunrise, with an older man in the driver's seat, pointing a video camera at him.

He's responded by videotaping adults bringing their own small children to the protest, complete with the large, graphic images of bloody aborted fetuses.

The family told 7NEWS they've been yelled at while simply doing yard work, as if they are somehow complicit in the construction man's endeavors.

They showed 7NEWS a plastic baggie filled with red liquid and a doll in the shape of an aborted fetus that they found at the end of their long driveway. Several neighbors found the same item early one Saturday morning, he said.

The neighbor said a couple of dolls were even found inside mailboxes.

The family said the construction executive felt so bad he came over to apologize to his neighbors for all the commotion. They told Hornaday there was no need to apologize.

The anti-abortion protestors said they're perfectly within their rights by demonstrating on public streets.

Protest organizers admit they have no idea what Hornaday's personal position on abortion may be but one said the construction man must clearly favor abortion, due to his participation in the project.

The anti-abortion group has dubbed this new shame tactic "The Collaborators Project."

The idea came from Will Duffy, with Colorado Families Against Planned Parenthood.

"For as many years as Planned Parenthood is killing children in this facility built by Weitz, we will be in their neighborhoods. Because there is no child killing with tranquility." said Bob Enyart, a Colorado Right to Life spokesman.

The issue of what to do with the protests on residential streets will come before the Greenwood city council on Dec. 17.

Mayor Nancy Sharpe said two emergency ordinances will be considered: they would limit the hours of the protests from sunrise to sunset, and would limit the size of signs to three square feet. In addition, another proposal would require groups of 15 or more to get a permit for a residential protest or parade.

"It is worrisome, " Sharpe said. "And as I said, we're just trying to balance what the rights of both groups are and have them both represented."

The mayor said if the council passes the measures on Monday, they would take effect on Tuesday.

Weekend calls to Planned Parenthood were not returned.
