Local high school parents are being asked to promise to supervise kids gathered in their homes and keep them away from drugs and alcohol.

The Project Conejo Safe Homes pledge will be available on the websites of Thousand Oaks, Newbury Park and Westlake high schools and the Conejo Council Parent-Teacher Association beginning Feb. 21. The names of parents and guardians who’ve signed will also be accessible.

The project was proposed by a Thousand Oaks High School parent after the death of senior Griffen Kramer, who overdosed on heroin in late October. The idea came from Royal High School in Simi Valley, which has distributed the form to parents for nearly a decade.

At Royal High, however, interest in the Safe Homes project has dwindled since it was introduced at the school about nine years ago, said former PTA president Harriet Hunsaker.

She said some parents might not be aware of the pledge, which can be found on Royal’s website. Others have said they can’t guarantee underage drinking won’t go on in their homes if someone outside the family brings in alcohol.

“Two years ago we had two pages filled with signatures,” said the PTA board member. “Now we have half a page. I wish it was more.”

Tragedy may be a catalyst for change. Kramer’s death was a wake-up call for some families, said Maria Steck, president of the PTA at Thousand Oaks High.

“I do believe there were families that didn’t realize these drugs are as prevalent as they are,” said Steck, whose two sons attend TOHS.

Some parents mistakenly believe that by allowing their kids to drink at home they can teach “responsible drinking,” she said.

“More and more parents think it’s okay to serve alcohol. It’s happening in our community,” Steck said. “We need to remind people we still need to protect our youth. They may be taller than us, but at 16, 17 they’re not adults. They’re not supposed to be drinking.”

The list will let other parents know which homes are safe for their children.

“It gives parents peace of mind to know that when their child is going over to someone’s house, alcohol won’t be served,” Steck said. “We’re not trying to dictate to parents. We’re trying to let other parents know whose house is a safe house.”

If the project is well-received by high school parents, middle schools may join by summer, she said. In the meantime, the mother hopes it will make a difference in someone’s life.

“If one family does do it and saves one child from having a tragedy, then it’s successful,” Steck said. “We’re trying to make sure bad things don’t happen to kids.”
