• of Guidelines and Specifications for Flood Ha~:ard Mapping Partners, CWCB shall make the following products available to FEMA: • Digital work maps showing the 1- and 0.2-percent-annual-chance floodplain boundary delineations, regulatory floodway bouridary delineations, cross sections, BFEs, flood insurance risk zone labels, and all applicable bas~~ map features; • DFIRM mapping files, prepared in accordance with the requirements in Guidelines and Specifications for Flood Hazard Mapping Par•tners; • Metadata files describing the DFIRM ciata, including all required information shown in Guidelines and Specifications for Flood Hazard Mapping Partners; • Complete set of plots of DFIRM panels showing all detailed flood hazard information at a suitable scale; • Documentation that describes and provides the results of all automated or manual QA/QC review steps taken during the preparation of tY~e DFIRM; • Any backup or supplemental information used in the mapping required for the independent QA/QC review outlined under Activit}~ 11; and • An explanation far the use of existing ~~opography for the studied reaches, if appropriate; • NSP Format Mapping Database ar Inte;rmediate Data Delivery consistent with the NSP Data Capture Standards. • Appendix N may be downloaded from the FE1~~A Flood Hazard Mapping Web site at http://~~v~~-.fema. oi=lpdf/fhu~/fim s~ana.pdf. Activity 10B - Floodplain Map~~ing (Itefinement or Creation of Zone A) Responsible Mapping Partner: CWCB Scope: CWCB shall delineate the 1-percent-aru~ual-chance floodplain boundaries for the flooding sources identified in Table 1-1. CWCB shall use existing topographic data or the topographic data acquired under Activity 4 to delineate the floodplain boundarif;s on a digital work map. In addition, CWCB shall address all concerns or questions regarding Activity l OB that are identified by FEMA/NSP during the indeperident QA/QC review under Activity 11. CWCB shall redelineate all approximate Zone A floodplain boundaries contained in the effective FIRM using the best available topographic data and/~r aerial photography. Redelineation of Zone A's shall be in confi~rmance with FEMA guidelines, including the data quality standards documented in Section 7 of the MH"IP for FY 2004-2008. The floodplain boundary data quality standards outlined in Table 7-1 of the MHIP should be followed in addition to existing standards specified for floodplain mapping in the Guidelines, including Volume I, Section 1.4 an~d Appendices C, D, E, F, G, H, K, L, M, and N. CWCB may expand on the approaches for analyzing Zone A areas outlined in Guidelines and Specifications for Flood Hazard Mapping Partners and in FEMA 265, Managing Floodplain Development in Approximate Zone A Areas (April 1995), and/or develop new approaches. Such approaches must be coordinated with the FEM.A Regional Project Officer identified in Section 11 of this . MAS before analys~s and mapping begin.
