• NSP Format Hydrology Database or Intermediate Data Delivery consistent with the NSP <br /> Intermediate Data Specifications. <br /> i <br /> Activity 7 -Independent QA/QC Review of Hydrologic 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 6 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 /> I <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 models; <br /> <br /> i <br /> - Use of appropriate methodology(ies); <br /> - Correctl a lied methodolo ies /models includin C of in ut arameters• <br /> Y pp gY(~ ) ~ g Q p P <br /> - Comparison with gage data and/or regression equations, if appropriate; and <br /> - Comparison with discharges for contiguous reaches or flooding sources. <br /> • Maintain records of all contacts, reviews, recommendations, and actions and make them readily <br /> available to FEMA. <br /> • Maintain an archive of all data submitted for hydrologic modeling review. (All supporting data <br /> must be retained for 3 years from the date funding recipient submits its fmal expenditure report to <br /> FEMA.) <br /> Standards: All work under Activity 7 shall be performed in accordance with the standards specified in <br /> Section 5 of this MAS. <br /> Deliverables: In accordance with the TSDN format described in described in Appendix M of Guidelines <br /> and Specifications for Flood Hazard Mapping Parrners, the NSP shall. make the following products <br /> available to FEMA: <br /> • A Summary Report that describes the findings of the independent QA/QC review; and <br /> • Recommendations to resolve any problems that are identified during the independent QA/QC <br /> review. <br /> Activity 8 -Hydraulic Analyses <br /> Responsible Mapping Partner: City of Eugene <br /> Scope: PWR shall perform hydraulic analyses for approximately 2.54 miles of the flooding sources <br /> identified in Table 1-1. The modeling will include the 10-, 2-, 1-, and 0.2-percent-annual-chance events <br /> based on peak discharges computed under Activity 6. Because of various complexities, both <br /> hydrologically and hydraulically, PWR will create an unsteady flow hydraulic model using HEC-RAS <br /> Version 3.1.2 for the subject flooding sources. <br /> Mapping Activity Statement No. 1 13 <br /> City of Eugene, OR <br /> - _ . <br /> <br />
