<br /> PWR shall use the cross-section and field data collected under Activity 3 to perform the hydraulic <br /> analyses. The hydraulic analyses shall be used to establish flood elevations and regulatory floodways for <br /> <br /> the subject flooding sources. <br /> <br /> PWR shall use the FEMA CHECK-RAS checking program to check the reasonableness of the hydraulic <br /> analyses. To facilitate the independent QA/QC review under Activity 9, PWR shall provide explanations <br /> for unresolved messages from the CHECK-RAS program, as appropriate. In addition, the study contractor <br /> shall address all concerns or questions regarding Activity 8 that are raised by FEMA (NSP) during the <br /> independent QA/QC review under Activity 9. <br /> Standards: All work under Activity 8 shall be performed in accordance with the standards specified in <br /> Section 5 of this MAS. <br /> Deliverables: Upon completion of hydraulic modeling for the flooding sources identified in Table 1-l, <br /> the City of Eugene shall submit the results to the NSP for an independent QA/QC review under Activity <br /> 9. In accordance with the TSDN format described in described in Appendix M of Guidelines and <br /> Spec cations for Flood Hazard Mapping Partners, the City of Eugene shall make the following products <br /> available to FEMA (NSP): <br /> • Digital profiles of the 10-, 2-, 1-and 0.2-percent-annual-chance water-surface elevations <br /> representing existing conditions using the FEMA RASPLOT program or similar software; <br /> • Digital and hardcopy versions of the Floodway Data Table for each flooding source that is <br /> compatible with the DFIRM database; <br /> • Digital versions of all hydraulic modeling (input and output) files; <br /> • Digital and hardcopy versions of a table showing ranges of Manning's "n" values; <br /> • Explanations for unresolved messages from the CHECK-2 or CHECK-RAS program, as <br /> appropriate; <br /> • Digital and hardcopy versions of all backup data used in the analyses; and <br /> • Digital versions of draft text for inclusion in the FIS report. <br /> • NSP Format Hydraulic Database or Intermediate Data Delivery consistent with the NSP <br /> Intermediate Data Specifications. <br /> Activity 9 -Independent QA/QC Review of Hydraulic Analyses <br /> Responsible Mapping Partner: FEMA (NSP) <br /> Scope: The NSP shall review the technical, scientific, and other information submitted by the City of <br /> Eugene under Activity 8 to ensure that the data and modeling are consistent with FEMA standards and <br /> standard engineering practice and are sufficient to prepare the DFIRM. This work shall include, at a <br /> minimum, the activities listed below. <br /> • Review the submittal for technical and regulatory adequacy, completeness of required <br /> information, and supporting data and documentation. The technical review is to focus on the <br /> following: <br /> - Use of acceptable model(s); <br /> - Starting water-surface elevations; <br /> - Cross-section geometry; <br /> Mapping Activity Statement No. 1 14 <br /> City of .Eugene;.
