In addition, an existing Threatened and Endangered (T&E) Species Report will also be expanded which includes : ■ A list of T&E plant and animal species that occur in the County and may occur onsite, ■ A summary of the methodology used to conduct the T&E survey, ■ The results of the T&E survey, and ■ Recommendations for permitting. Subtask 220 Development of Wetland Mitigation Plan As required, impacts must be avoided and minimized to the extent possible . Mitigation must be provided for unavoidable wetland impacts and a mitigation plan to address wetland impacts will be developed . During the Consumptive Use permitting, a high quality wetland was identified which needs to be avoided . The conceptual layout will be modified to make this change and avoid impacts to this wetland . The wetland mitigation plan will address impact compensation (FDEP and USAGE) , design and specifications, construction issues, monitoring and maintenance requirements and costs . The wetland mitigation task will include : ■ a functional assessment of each wetland for which a jurisdictional boundary is determined ■ develop a wetland mitigation approach. This will include an assessment of the wetland mitigation property and how best to improve and enhance it to provide maximum value to SWDD for mitigation credit. ■ develop a permitting design for the wetland mitigation property . This will include several engineering drawings which detail the design. ■ develop a narrative which describes the mitigation plan to be included in the ERP application. Subtask 230 Stormwater Management Plan and Layout CDM will prepare the stormwater management system portion of the ERP application and submit it to the FDEP. The stormwater portion of the application consists of ERP Sections A, C, and E . The stormwater portion of the ERP will serve as a modification to the existing landfill facility stormwater permit. The C-5 Canal currently does not receive runoff from the landfill. The ERP stormwater management application will describe and show the connection from the C-5 Canal south to the C-6 Canal and the required improvements to the C-6 canal for conveyance . The submittal will also show how drainage on the southeast corner of the Northern Expansion property will be routed south through the existing stormwater system. Pre- and post development drainage calculations must be provided. Runoff characteristics for design storms and stage-storage and stage-discharge computations for storage areas must also be provided along with their expected level of water quality treatment.
