PUBLIC SCOPING MEETING

FOR THE

ARROYO SECO ENVIRONMENTAL RESTORATION INTEGRATED FEASIBILITY STUDY/ENVIRONMENTAL IMPACT STATEMENT

LOS ANGELES COUNTY, CALIFORNIA

The United States Army Corps of Engineers (Corps), Los Angeles District will hold a Public Scoping Meeting in support of the Arroyo Seco Environmental Restoration Integrated Feasibility Study and Environmental Impact Statement and Environmental Impact Report on Wednesday October 29, 2014, from 6:00-8:30 p.m., at the Los Angeles County Department of Public Works at 900 S. Fremont Ave., Alhambra, CA 91803. The National Environmental Policy Act (NEPA) requires the lead agency (Corps) to invite the participation of affected Federal, state, and local agencies, as well as other interested persons to determine the scope and significant issues to be analyzed in depth in the EIS.

The purpose of this meeting is to identify issues or concerns in advance of preparing an EIS as well as solicit input from the public. The public, as well as Federal, state, and local agencies are encouraged to actively participate in the scoping process by attending the meeting and/or submitting data, information, and comments pertaining to environmental issues to be addressed in the EIS. Useful information includes other environmental studies within the watershed, published and unpublished data that may be relevant to this study area, issues and alternatives which could be addressed in the analysis, and potential constraints associated with any proposed action.

Over its 22-mile course, the Arroyo Seco drops from an elevation of nearly 6,100-feet at its head in the San Gabriel Mountains to 320-feet at its confluence with the Los Angeles River. As the Arroyo descends from the San Gabriel Mountains, it passes by NASA's Jet Propulsion Laboratory (JPL) and enters the 250-acre basin within Hahamongna Watershed Park and Devil's Gate Dam. Below the dam, the Arroyo is highly impacted by urbanization and is channelized as it runs through Brookside Park and the Rose Bowl area. From here the Arroyo meets the Arroyo Seco Historic Parkway (Pasadena Freeway), a Federal Scenic Byway and the first freeway in the west. Between 1934 and 1947 most of the Arroyo Seco below the dam was lined with concrete.

The Integrated feasibility report will identify and evaluate an array of restoration measures including: (1) restoration of channel sinuosity; (2) removal of concrete invert; (3) restoration of aquatic habitat; and (4) eradication of invasive, non-native species and restoration of native taxa.

The EIS will also evaluate the impacts on environmental resources initially identified as potentially significant without implementation of mitigation measures include, but are not limited to: water quality, noise and vibration, air quality, socioeconomics and environmental justice, land use, recreation, visual and aesthetic resources, traffic and transportation, historical and cultural resources, vegetation and wildlife, and special status species.
