ESCONDIDO -- More than a year after a pair of noisy, incessant partiers moved onto Alexander Drive, residents in the unincorporated Escondido neighborhood say the din has finally faded.

The neighbors -- about two dozen in all -- recently used a program known as Safe Streets Now to oust the residents, whom they said blasted music past 3 a.m. and hosted parties that led to violent fights, speeding cars and suspected drug use.

One neighbor, who asked not to be identified, said it was so bad that she wouldn't let her children in the backyard because of the "loud, booming music, parties, beer bottles (and) foul language."

B.J. Williams, a sheriff's crime prevention specialist who helped the residents implement the program, said that deputies were called to the house 48 times between April and November last year, when problems peaked. Most of the calls were for disturbances and loud parties, though burglaries, stolen vehicles and illegal dumping were also reported, as well as a violent fight that led a sheriff's helicopter to search several hours for the bloodied victim.

Deputies also made three arrests at the home, Williams said.

"It really was a problem house," she said.

As part of the program, residents kept daily logs of problems and concerns about the house. Then, the county Safe Streets director sent a letter detailing the neighbors' complaints to the resident -- identified in the notice as Zoltan Jaszberenyi -- giving him 30 days to respond or face the possibility of a civil lawsuit.

Jaszberenyi could not be reached for comment.

Leo Wilson, director of the San Diego Safe Streets program, said the Alexander Drive home follows an emerging pattern in which problem houses arise in generally quiet, affluent neighborhoods not used to loud residents and ruckus.

"People now have zero tolerance, they're not used to this type of activity," he said of those residents. "Now, half (of the cases) are in affluent neighborhoods … this really was unexpected."

Williams agreed, saying that the cases she handles in unincorporated areas around San Marcos, Escondido and Valley Center "are in neighborhoods you wouldn't expect."

She is also working on three other cases in those areas, she said.

The Safe Streets Now program was founded by Oakland residents in 1989 to help them combat drug houses and public nuisances, including drug dealing, gang activities, prostitution, illegal sales of alcoholic beverages, excessive noise and blight.

Used now by the county Sheriff's Department and San Diego, Carlsbad and Escondido police departments, it is a last-resort program that helps residents resolve problems through civil litigation after police -- who serve as liaisons -- have taken all the action that they can.

This case, Wilson and residents said, never made it to court.

After the letter was served in September, the home quieted down until April, when deputies again began receiving calls, Williams said.

The residents then moved, for unknown reasons, on the week of May 14, neighbors said.

"(Problems) ended when they moved," Wilson said. "It's hard to say exactly what happened.

"It appeared to be a foreclosure, it was one of those things where they say they're going to sell to move somewhere else where they can have parties, and then they walked away pretty suddenly."
