- Manning's "n" values and expansion/contraction coefficients; <br /> - Bridge and culvert modeling; <br /> - Flood discharges; <br /> - Regulatory floodway computation methods; and <br /> - Tie-ins to upstream and downstream non-revised Flood Profiles. <br /> • Use the CHECK-RAS program as appropriate to flag potential problems and focus review efforts. <br /> I <br /> • Maintain records of all contacts, reviews, recommendations, and actions and make them readily <br /> available to FEMA. <br /> i <br /> • Maintain an archive of all data submitted for hydraulic modeling review. (All supporting data <br /> <br /> ~ must be retained for 3 years from the date funding recipient submits its final expenditure report to <br /> FEMA) <br /> Standards: All work under Activity 9 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 Partners, 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 /> Due to funding limitations, the City of Eugene has broken this mapping project into various phases. <br /> Phase 1 was a scoping phase that included the development of the Phase 2 scope of work. Phase 2A <br /> includes the first seven tasks in PWR's scope of work dated June 8, 2004 with the City that begins with a <br /> review by PWR of this Mapping Activity Statement (MAS) and concludes with the delineation of the <br /> floodplain and floodway boundaries (i.e. the scope of Activity 10) but not the submittal of this <br /> information to FEMA (i.e. the deliverables under Activity 10). So Phase 2B includes Activities 2 through <br /> 10 of this MAS. Phase 2B starts with the Activity 10 deliverables and concludes with Activity 15, the <br /> Post Preliminary Processing. <br /> Activity 10 - Floodplain Mapping (Detailed Riverine Analysis) <br /> Responsible Mapping Partner: The City of Eugene <br /> Scone: PWR shall delineate the 1-and 0.2-percent-annual-chance floodplain boundaries and the <br /> regulatory floodway boundaries for the flooding sources identified in Table 1-1. PWR shall incorporate <br /> all new or revised modeling and shall use the topographic data acquired under Activity 4 to delineate the <br /> floodplain and regulatory floodway boundaries on a digital work map. PWR shall incorporate the results <br /> of all effective Letters of Map Change (LOMCs) within the revised areas as appropriate. Also, the study <br /> contractor shall address all concerns or questions regarding Activity 10 that are raised by the NSP during <br /> the independent QA/QC review under Activity 11. <br /> Standards: All work under Activity 10 shall be performed in accordance with the standards specified in <br /> Section 5 of this MAS. <br /> Deliverables: Upon completion of floodplain mapping for the flooding sources identified in Table 1-1, <br /> the City of Eugene shall submit the mapping to the NSP for an independent QA/QC review under <br /> Mapping Activity Statement No. 1 15 <br /> City of Eugene,', OR <br /> _ <br /> <br />
