Draft Supplemental Environmental Impact Report Page IV.F-28 Forward Inc. Landfill 2018 Expansion Project • 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. ' • The stated goal of the mitigation effort shall be to establish self-sustaining creek channel habitat that shall not require long-term irrigation or maintenance. • The mitigation site shall include the establishment of a vegetated upland buffer no less than 50 feet wide on both sides of the recreated channel,where practicable. • Provide grading details, location and quantities of all plant materials to be planted or seeded, native seed mixes to be used on all bare ground surfaces,monitoring procedures and schedules,identification of remedial measures, and performance criteria to be used by the agencies to assess success or failure of the mitigation effort. ' • Long-term monitoring over a minimum of five years shall be funded by the Project Sponsor, subject to approval by the regulatory agencies. • Annual monitoring reports shall be submitted to each permitting agency. • A wetland delineation and habitat map shall be prepared during the final year of monitoring and included in the final annual report. ' Subject to review and modification by the regulatory agencies,specified success standards shall call for, at a minimum, 1:1 replacement of the creek channel that currently occurs, as detailed in the most recent wetland delineation report, at the end of the monitoring period. Off-Site Wetland Mitigation ' In addition to the approximately 1.87 acres of wetlands to be created onsite, if required as a permit condition, additional mitigation credits may be purchased from a qualified wetland ' mitigation bank with a Service Area that covers the project site, or as otherwise approved in advance by the USACE and RWQCB. For example,the expanded Service Area of the Cosumnes Floodplain Mitigation Bank covers the project site.This mitigation bank sells Floodplain Mosaic Wetlands credits(404) credits that would appropriately mitigate impacts to wetlands within the existing channel.This, in combination with the onsite jurisdictional habitat mitigation,would provide opportunities (if needed)to comply with a higher permit-required replacement ratio for wetland impacts, and also provide opportunities for riparian habitat mitigation. In lieu of purchasing mitigation credits,if additional wetland mitigation(greater than the 1.87 acres proposed as part of the project)is required as a permit condition, the Sacramento District ' of the USACE has an"In Lieu Fee Program" to which the project sponsor may make payment. The fee is based on a fee schedule for various wetland habitat types.The fee is payable to the National Fish and Wildlife Foundation(NFWF)to be deposited in NFWF's Sacramento District Wetlands Conservation Fund. This mitigation measure would reduce significant impacts to the Creek and associated ' jurisdictional resources to less than significant levels because it would provide restored habitat at an equal or greater value to the lost habitat within the relocated creek segment, and provide for compliance with the conditions of permits to be issued by the USACE, RWQCB, and CDFW.
