Los Angeles River Jurisdictional Determination Special Case Cover
UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION IX 75 Hawthorne Street San Francisco, CA 94105·3901 JUL 6 2010 OFFICE OF THE REGIONAL ADMINISTRATOR Colonel Mark Toy District Engineer, Los Angeles District U.S. Army Corps of Engineers P.O. Box 532711 Los Ange les, California 90053-2325 Dear Colonel Toy: This letter transmits the Clean Water Act (CWA) jurisdictional determination for the Los Angeles River. On August 17, 2008, EPA's Assistant Administrator for Water designated the Los Angeles River as a "Special Case" as defined by the EPA-Corps 1989 Memorandum ofAgreement (MOA) regarding coordination on matters ofgeographic jurisdiction. Pursuant to the MOA, designation ofthe "Special Case" made EPA responsib le for determining the extent to which the Los Angeles River was protected as a "water ofthe United States." Specifically, EPA analyzed the river's status as a "Traditional Navigable Water," one ofseveral categories ofjurisdictional waters under the Act. We conclude that the mainstem ofthe Los Angeles River is a "Traditional Navigable Water" from its origins at the confluence of Arroyo Calabasas and Bell Creek to San Pedro Bay at the Pacific Ocean, a distance of approximately 51 miles . In reaching this conclusion, Region 9 and Headquarters staffconsidered a number offactors, including the ability ofthe Los Angeles River under current conditions offlow and depth to support navigation by watercraft; the history ofnavigation by watercraft on the river; the current commercial and recreational uses of the river; and plans for future -

These tools will be used to inform development of flow criteria that sustain specific species, habitats, and beneficial uses. This toolkit may be used to develop policies on how to balance the need for local water supply and still support beneficial uses. In the near term, the outcomes of this analysis can inform decisions associated with proposed wastewater change petitions and stormwater management programs. In the longer term, the outcomes could inform decisions regarding the ability to support beneficial uses not currently supported, in combination with broader restoration planning efforts. -

A Brief History of Water Development in the Arroyo Seco
Page 1 Flowing Waters, Fruitful Valley A Brief History of Water Development in the Arroyo Seco By Tim Brick Geographically and historically the Arroyo Seco has played an important role in the development of water resources in Southern California. The Natural History Geology divided the Arroyo Seco into three distinct sections with very different hydrologic characteristics: 1) the precipitous upper mountain watershed; 2) the Raymond Basin area including Pasadena and surrounding communities; and 3) the region below the Raymond Dyke in South Pasadena and northeast Los Angeles. About half the length and area of the Arroyo Seco lies in the upper mountain watershed. This is the front range of the Sierra Madre or San Gabriel Mountains, well known for their harsh conditions. Fierce rainstorms and raging forest fires periodically attack the steep erosion-prone slopes in this relatively small upper watershed (32 square miles) to create the conditions for substantial floods that occasionally roar into the heavily populated communities below. As the Arroyo Seco emerges from the San Gabriel Mountains, its steep descent slows and the waters cut through an alluvial plain. Beneath this region, which includes La Cañada-Flintridge, Altadena, Pasadena, Sierra Madre and part of Arcadia, lies the Raymond Basin – a massive bowl of alluvial sand and gravel filled with water. The south rim of the basin is the Raymond Dyke, a geological fault that runs from Highland Park to Raymond Hill at Pasadena’s southern boundary with South Pasadena and then through San Marino just north of Huntington Drive to Santa Anita Canyon on the east side of Arcadia. -
