Document Description
The purpose of the proposed project is to upgrade the protection along the river bank to provide the JSCD Plant 1 facility with 100-year flood protection. In January of 2005, high rain fall in Southern California caused flooding of the Santa Ana River. During this event, JCSD's Wastewater Regional Plant 1 Facility was at risk of being flooded as the Santa Ana River migrated approximately 200 feet towards JCSD's storage ponds and regional lift station. JCSD stabilized the slope by placing riprap along the north bank of the Santa Ana River to protect JCSD's Plant 1 from flood damage. The existing riprap spans a portion of the project area's southern border along the Santa Ana River. The riprap protected Plant 1 from being flooded in 2005 but the existing proximity of the river channel now to the Plant 1 facility has left the site at risk of flooding in future events. The River continues to erode the bank along JCSD's property. If the slopes are not stabilized, erosion could result in the introduction of wastewater into the Santa Ana River system, thereby potentially polluting downstream water sources. The project will include placement of launchable windrow revetment 1/4 ton riprap, herein after referred to as launchable riprap, along the southern property line of the Plant 1 facility. The project will include applying launchable riprap north of and partly over the existing riprap to reinforce the bank and to extend the riprap protection along the southeast and southwest portions of the JSCD Plant 1 and into the river channel.
