Heading Bullet    Big Tujunga Wash at Oro Vista Avenue Maintenance Program

Negative Declaration/Initial Study (ND/IS) for the Big Tujunga Wash at Oro Vista Avenue Maintenance Program consists of the the long-term clearing, cleaning, maintaining, repairing, and restoring of Oro Vista Avenue and associated berms, swales, and shoulders that are located within the Big Tujunga Wash. At the end of the Southern California rainy season (October to April), and/or after major storms (December to March), and/or after a major release of water from the Big Tujunga Dam, the City would remove accumulated sediments (i.e. sands, mud, boulders, etc.) and debris (i.e., trash, logs, trees, brush, etc.) that block the flow of waters under the bridge, through the culverts, or over the Arizona Crossing, uptream and downstream of Oro Vista Avenue. All work will be accomplished shortly after major flows have ceased and most all ground cover would have been removed due to water flows and scouring. The project will recreate berms and swales in Big Tujunga Wash as needed to restore it to its pre-storm flow, pre-storm season, or pre-discharge of waters from Big Tujunga Dam, (i.e., under bridge, through culverts, or over Arizona Crossing). There will be no new stream channelization or relocation.
