14 Finalize Covered Activities Step 1: Review Covered Activities Information Evaluate and confirm the Covered Activity information you have provided to date. GIS data text describing qualitatively and quantitatively the construction, operations, and maintenance of each covered activity points of diversion or discharge current and proposed future diversion flow rates current and proposed future basin capacities Step 2: Online Meeting with ICF Review Covered Activities information with ICF in online meeting Provide all corrections to text, GIS, and potential hydrologic effects the corrected covered activity document to ICF prior to this online meeting. Step 3: In Person Meeting with Valley District Meet with Valley District in Early December to confirm final Covered Activity information Final covered activity information must be confirmed by each participating water agency during the first week of December. icfi.com 14
