anticipated impacts of sea level rise, flooding, and storm surge on the parcel and the proposed project, based upon a review of approved models and forecasts, to include the following: 1. For sea -level rise, the 2017 National Oceanographic and Atmospheric Administration (NOAA) Intermediate -High scenario projection curve (or any subsequently updated version thereof) on the project site. Sea level rise data can be accessed on the AdaptVA website, maintained by the Virginia Institute of Marine Science (VIMS). 2. For storm surge, the most up to date NOAA hydrodynamic Sea, Lake, and Overland Surges Hurricanes (SLOSH) model. Storm surge data can be accessed on the AdaptVA website. Category 1 storm surge data should be used. 3. For flooding, the most up to date Special Flood Hazard Area (SFHA) and the Limit of Moderate Wave Action (LIMWA) model according to the Virginia Flood Risk Information System (VFRIS) model in conjunction with the requirements and application of Chapter 14.1 Flood Protection. VFRIS includes the Flood Insurance Rate Maps, flood insurance studies, and associated models produced by the Federal Emergency Management Agency, and is available on the Virginia Department of Conservation and Recreation (DCR) website. This data is also accessible on the AdaptVA website. 4. The anticipated impacts shall be based upon a thirty (30) year timeframe. b. A narrative report that analyzes the results of the data and graphic research, and provides the following information: 1. Identification of any proposed impact directly from proposed impervious cover or structures in the RPA and the extent of such impact. 2. Identification of extent of impact on the current buffer area including impacts to existing vegetation from the landward movement of water and vegetative migration. Describe the extent to which anticipated impacts can be or have been mitigated by altering the location design, size, or orientation of proposed structures or impervious cover, by preserving and/or supplementing existing buffer areas, and/or by considering other limiting site conditions including required setbacks and parcel size, and/or by proposing an adaptation measure. c. The director of planning will review the resiliency assessment along with the water quality impact assessment and determine whether the anticipated impacts necessitate an alteration or conditions to the proposed project or implementation of an adaptation measure for approval. In considering whether a requirement for project alteration or adaptation measure is appropriate, the planning director will ensure that the proposed alteration or adaptation is practical, achievable, and necessary to mitigate the identified impact. 21
