When Magic Mountain opened 35 years ago, the theme park was billed as a magnet for development in the cattle ranches and pastoral hills of northern Los Angeles County — much as a certain magic kingdom had put an obscure southern outpost on the map 15 years earlier.
"Remember what Disneyland did for property values in Anaheim?" read one real estate ad in 1970. "You should be living here when the Mountain comes. Your property values should be all uphill from here."
Move there they did, by the thousands, making the Santa Clarita Valley and surrounding region the fastest-growing section of Los Angeles County.
As more suburbanites flooded the north county, their relationship with the amusement park was mixed: It generated jobs and taxes, but residents disliked the traffic and crime that periodically caused problems.
But now, as Magic Mountain's owners talk about shutting it down and selling the 250 acres for development, residents are rallying to keep it around.
Their desire to save the park is driven both by nostalgia for the past and concerns about future development.
"I've never known a Santa Clarita without Magic Mountain," said Santa Clarita Councilman Cameron Smyth, who grew up in the area and worked as a ride operator as a teen. "It's part of the community … and it's a landmark for the Santa Clarita Valley."
North L.A. County is in the midst of a major building boom — adding an estimated 350,000 residents in the next 15 years — and some residents say the region cannot handle another mega-development.
North of Magic Mountain, nearly 21,000 homes are rising on the old Newhall Ranch. Farther up Interstate 5, 23,000 homes are slated for the new community of Centennial near Tejon Ranch. And 15,000 to 20,000 homes are planned on the eastern edges of Santa Clarita.
"The growth here has been just ridiculous," said Valencia resident Jennifer Molidor, 34, who worked at the park as a photographer when she was a teenager and now takes her children there. "I think we have enough housing here."
Molidor and others in Santa Clarita say it is ironic that Magic Mountain has become a victim of the development boom that it helped create.
The Santa Clarita Valley's population was about 48,000 — plus at least 6,000 head of cattle — in 1971 when Magic Mountain opened. Now, it is 170,000 and growing. What started as a middle-class bedroom community has become an upscale suburb with high-end shopping as well as technology and entertainment businesses.
But as homes spread around Magic Mountain, residents grew unhappy about the crowd the park attracts.
While Disneyland has long catered to families, Magic Mountain has always been a magnet for teenagers lured by the venue's 17 roller coasters. Teen troublemakers have been a periodic problem.
Several high-profile crimes dismayed residents, including a gang-related stabbing spree in 1985, a riot that spilled from the park to businesses in 1993 and the shooting death of a teen in the parking lot in 1998.
"Once you burn Mom, she is not rushing back," Shapiro said.
Although Shapiro said it was possible that Magic Mountain would be sold to another theme park operator, some real estate experts have said the land is so valuable that converting it for housing or housing-retail development probably would yield the greatest profit.
Real estate experts estimate that the land could be worth at least $200 million.
But many in the Santa Clarita Valley say the region does not need more housing tracts. With traffic worsening and massive developments rising at a rapid clip, north county leaders are struggling to attract more jobs.
