CDFW is intending to execute a lake and streambed alteration agreement pursuant to section 1602 of the fish and game code (#1600-2014-0097-R5) to the project applicant, Lakeside's River Park Conservancy. The project proposes to alter the stream to construct the Hanson El Monte Pond Flood Control, Restoration, and Recharge project. Project activities will be phased, as follows. Phase 1 consists of project surveying and utility mark out, installation of limit of work/environmental fencing, placement of temporary construction trailers, storage bins, portable sanitation stations and connection of temporary utilities, including temporary electricity and water services. Phase 1 will not disturb native vegetation nor create sustained noise levels above 60 dB and therefore may be initiated during the migratory bird nesting season. Phase 2 includes clearing and grubbing of site vegetation, demolition/removal of old abandoned quarry foundations, pipes and other infrastructure, installation of a turbidity curtain within the pond, and site grading. Grading work includes grading the area south of the pond to lower elevations in order to establish additional wetlands, placing cut soil into the southern portion of the pond to make it more shallow, and re-countouring the steep slopes located in the southeastern portions of the pond for safety and stability reasons. Rock and/or clean recycled concrete may be placed in the pond to create an underwater revetment to stabilize the in-pond fill soil and preclude lateral movement. This phase also includes the installation of an arched culvert inlet structure in the northeast portion of the project site. Phase 3 includes habitat establishment, restoration and enhancement activities including removing and spraying invasive species and weeds, planting and seeding the appropriate native plants, and installing a temporary irrigation system in order to establish native plantings.
