Page 13 Consolidated For`vard In ndfill site. The surface-water collection drai-. system will be designed to divert the water to the storm water collection basin in the sou:nwest corner of the current Austin Road Landfill, at times when enough surface water acc=.-:ulates to have discharged into the collection basin. All waste at the proposed Forward Landnll will be separated from the north and south branches of Littlejohn Creek by a levee s`'stem or other acceptable method designed to protect the site from a 100-year flood event. The project includes channel reconfig�'ation and localized flood protection berms to isolate the landfill surfaces from floodwaters. Yee The project design also includes proV=_on of replacement flouth Fork of South Littlejohn odplain area and storag glume in an easement along the relocated\c._a Bran ch ofCreek. The channel and floodplain storage ea:-e•llent are designed to accommodate the 100-year, 24- hour storm. The design also includes =;nree-foot freeboard. 45 (F.2) Proposed as Part of the Project: The JTD articulates the programs of,-- na°e control structures and monitoring to inhibit ntrol system erosion and sedimentation.

The JTD and the a dequacRy`�oQf CB leachate collection system and associated monitoring are under re z y The re ulatory required separation between the liner and groundwater will be implemented to g - allow for chemicals in the leachate to attenuate before reaching the groundwater, should the leachate breach the collection system. The project design includes a leak detection system under the sumps. The liner system will be overlain by a protective operations laver consisting of a one thickness of soil and gone-foot thick gravel layer that serves as the leachate collection layer. This two-foot layer will serve to p-orect the liner system from sharp or jagged materials the in waste.
