Environmental Groups Settle with Magic Mountain on Stormwater Runoff Pollution

The following press release was issued on March 31, 2015 regarding settlement of a lawsuit by FSCR and others against Magic Mountain for violation of water quality standards in stormwater discharges.  This settlement will require the facility to comply with much stricter limits on a range of pollutants including trash and metals such as copper, zinc and aluminum, which are harmful to aquatic species in the Santa Clara River. 

Los Angeles, California – March 31, 2015 (Los Angeles, CA) –  Recently the Los Angeles Waterkeeper, Wishtoyo Foundation, Wishtoyo Foundation's Ventura Coastkeeper Program, and Friends of the Santa Clara River reached an agreement with Magic Mountain to address pollution in the Santa Clara River. The environmental groups filed a lawsuit in 2012 under the federal Clean Water Act, alleging that the amusement park's stormwater discharges violate water quality limits.

"This agreement marks a significant step in the stewardship of the Santa Clara River – an incredibly important watershed to nearby communities and several endangered and threatened species," said Liz Crosson, Executive Director of Los Angeles Waterkeeper. 

Bonnie Rabjohn, Park President of Magic Mountain, stated "Magic Mountain is committed to protecting our environment and we look forward to working with these organizations over the next few years to improve water quality and support conservational business practices."

In addition to making a substantial contribution to an environmental project designed to protect the Santa Clara River, Magic Mountain will develop and implement an improved Facility Trash Management Plan as well as new and improved best management practices to ensure compliance with the Clean Water Act and to protect the Santa Clara River.

"Magic Mountain's agreement to better management practices that affect the Santa Clara River will improve the health of the river and will give its wildlife and resources a chance to recover. It is our responsibility to protect the history of Chumash life to assure the continuum of our Traditions today and into the future," said Mati Waiya, Chumash Ceremonial Elder and Executive Director of the Wishtoyo Foundation and its Ventura Coastkeeper Program.

"This commitment by Magic Mountain properly protects the birthrights of the communities we represent from Valencia, Santa Clarita, Piru, Fillmore, Santa Paula, Saticoy, El Rio, Ventura, and Oxnard to a clean and healthy Santa Clara River that contains an abundance of native species and ample recreational, wildlife viewing, and educational opportunities," said Jason Weiner, General Counsel for Wishtoyo and its Ventura Coastkeeper Program.

Flowing approximately 116 miles from the headwaters of the San Gabriel Mountains to the Pacific Ocean through a 1,600 square mile watershed, the Santa Clara River is southern California's last naturally flowing major river system. In addition to being the largest wild river remaining in southern California, the Santa Clara River is home to as many as 17 species listed as threatened or endangered by state and federal governments, including the Southern California Steelhead, and provides unmatched recreational, cultural, aesthetic, and spiritual opportunities and resources in the region.

"The settlement agreement, the culmination of an involved legal process, represents a major step forward in protecting the water quality and wildlife of the Santa Clara River ecosystem," said Ron Bottorff, Chair of the Friends of the Santa Clara River.

Environmental Review Continues on Homestead South - Newhall Ranch Project Third Phase

The Homestead South tract map (above), the third phase of the Newhall Ranch Project,  proposes development of 3,617 residences and 66,400 square feet of retail commercial uses.  This phase, one of the most environmentally damaging of the entire project, will involve massive impacts to the Santa Clara River and its tributaries.  It will necessitate the construction of the Long Canyon bridge across the Santa Clara River from Landmark Village, which by itself will have many severe impacts to river habitat and aquatic species. 

In addition, this phase proposes 35.7 million cubic yards of cut, of which 29.9 million cubic yards will be used as fill on the project site (much of it within the river floodplain) and 5.8 million cubic yards transported across the river to be used as floodplain fill in Landmark Village.  Large acreages of wetlands and riparian habitats will be lost - these will be further defined and studied in the forthcoming EIR. 

Overall, the Newhall Ranch Project involves impacts to the Santa Clara River and its tributaries on a scale that is difficult to comprehend.  The Project would result in the permanent elimination of about 110 acres of the Santa Clara River's 100-year floodplain, which would be built up and filled with houses.  An immense volume of material would be excavated from the site to flatten hilltops and fill valleys – approximately 207.5 million cubic yards of soil, constituting in EPA's view twice the volume of the largest previous grading project in southern California.  About 10 percent of this material – 19.9 million cubic yards – would be dumped into rivers and streams.

The Project as designed would also include two bridges crossing the Santa Clara River, three bridges and 13 culvert roads crossing tributaries, 35 drainage outlets into the Santa Clara River, and other infrastructure. The Project would involve nearly five miles of buried soil-cement bank stabilization along the Santa Clara River, which would alter and permanently confine the river channel.  About 9 miles of tributary streams would be converted to buried storm drains, and another 7 miles of streams would be filled and reconstructed on top of filled areas.

But there is hope this can all be revised to achieve a much better outcome for the Santa Clara River ecosystem.  FSCR and our allies - the Center for Biological Diversity, SCOPE and Wishtoyo Foundation's Ventura Coastkeeper Program - are currently involved in litigation against the Army Corps of Engineers opposing its issuance of a Clean Water Act permit that would allow impacts of this severity to the Santa Clara River watershed.  Stay tuned.
