Forward Inc. Landfill Expansion Project MMRP ' testing events shall be initiated by the applicant in coordination with the RWQCB to detect an changes in water quality that may signer subsurface adjustments in landfill cells. 73. Forward 1993(B.6) Benchmarks shall be established(these could utilize monitoring well top of casing elevations), which will allow for determinations of settlement/consolidation of fill materials ' in closed sections of the landfill on an annual basis and following significant seismic events (Modified Mercalli Scale of V or above). In the event that changes are noted, the cause ' should be determined as should the effect on leachate collection and recovery systems. Repair liners and LCRS as necessary. In addition, remedial grading should be accomplished to restore the original cap's function to repel water and direct surface runoff. H. BIOLOGICAL RESOURCES ' 74. (F.1.)Identified in this SEIR: ' Prior to site grading,the project sponsor shall obtain re-verification of the jurisdictional delineation conducted for the project;this will ascertain the extent of jurisdictional waters and wetlands on the site,including the creek and potentially onsite storm control features (detention basins,dry ditches). The re-verified jurisdictional delineation will serve to confirm the acreage of jurisdictional area to be impacted and for which mitigation will be provided. Prior to site grading,the project sponsor shall obtain permits under Sections 401 and 404 of the Clean Water Act and Section 1602 of the California Fish and Game Code for all impacts to jurisdictional 1 resources; all permit conditions shall be implemented. At a minimum,an equivalent acreage of jurisdictional area to be impacted shall be established within the relocated segment of the South Branch of the South Fork of Littlejohn's Creek(1:1 in-kind replacement of jurisdictional habitats impacted by the creek relocation), and if required by permit conditions, additional compensatory mitigation will be purchased from an USACE,RWQCB and/or CDFW-approved wetland mitigation bank. These mitigation components are discussed further below. Onsite Replacement of Jurisdictional Habitat A Creek Channel Mitigation and Monitoring Plan shall be prepared and submitted for agency review to ensure a"no net loss"of wildlife value or acreage of creek habitat. At a minimum,the Plan shall include the creation of the equivalent(in-kind)acreage of jurisdictional habitat within the relocated segment of the South Branch of the South Fork of Littlejohn's Creek. The Concept Design Report(Questa 2017)indicates that approximately 1.87 acres of creek habitat would be created in the longer,relocated creek channel, so an increase in jurisdictional habitat(1.87 acres vs. 1.25 acres)is anticipated. The Project Sponsor shall ensure that the mitigation area,along with an appropriate upland buffer, are preserved in perpetuity via recordation of a deed restriction or similar easement. The Creek Channel Mitigation and Monitoring Plan shall include the following details: ' • The location(s)of mitigation areas,including the types and extent of each habitat type to be created. • Mitigation for loss of existing jurisdictional habitat shall at a minimum include the creation of ' equivalent acreage of jurisdictional habitat present within the channel(as determined by the re-verified jurisdictional delineation). Mitigation habitats shall replace the existing functions and services provided by the impacted channel. • All graded areas within the habitat restoration area shall be seeded with appropriate mixes of ' California native grass and forb species, developed by a qualified restoration ecologist. 1 Page 22
