Document Description
The Project consists of the beneficial reuse of excess sediment excavated from flood control facilities and disturbed habitats in the Tijuana River Valley towards the reclamation of previously quarried slopes and restoration of the Nelson Sloan Quarry site to close to historic (i.e., pre-quarry operations) topography and habitat. Over an approximately 10-year period, up to 1,000,000 cubic yards of excess sediment extracted from flood control facilities and habitat restoration projects managed by federal, state, and local agencies in the river valley that are currently hauled off site to area landfills or construction projects would instead be characterized and hauled to the Project site for sorting and placement. The sediment would be used to (1) reclaim the oversteepened slopes associated with previous quarry operations and remove Surface Mining and Reclamation Act regulatory jurisdiction over the site and (2) restore the site to close to historic topography and habitat. In a phased approach, suitable sediment would be deposited and regraded to a stable condition on the eroded slopes of the eastern portion of the Project site and, in later phases, placed and stabilized on site to create new terrain and habitat. Erosion and drainage control measures and revegetation of regraded areas with appropriate native plant material would also be implemented.
