(Source: FEMA Guidelines and Standards for Flood Risk Analysis and Mapping)\r\n\t Recent innovations and efficiencies in floodplain mapping have allowed FEMA to develop processes called Large Scale Automated Engineering and Base Level Engineering, which can be used to address current program challenges including the validation of Zone A studies and the availability of flood risk data in the early stages of a Flood Risk Project. The Large Scale Automated Engineering and Base Level Engineering processes involve using best available data and automated techniques to mass produce estimates of flood hazard boundaries for multiple flood recurrence intervals.\r\n The objective of this Hydrology data submission is to archive the hydrologic data for a study in a database such that it can be revised and used with minimum effort in future Flood Insurance Studies or map revisions.\r\n\t The Large Scale Automated Engineering and Base Level Engineering processes leverage the best available data and methods and use automated techniques to mass produce estimates of flood hazard boundaries for multiple flood recurrence intervals. These data may be used to evaluate Zone A studies in the Coordinated Needs Management Strategy (CNMS) inventory that are unknown or that require revalidation. Additionally, Large Scale Automated Engineering or Base Level Engineering data can be used in the Discovery process to identify the potential changes in flood elevation and extent that may result from a proposed project scope and share this information with stakeholders. Another important goal of the Large Scale Automated Engineering and Base Level Engineering processes is the scalability of the results. Scalability means that the results of Automated Engineering can not only be used for CNMS evaluations of Zone A studies and Discovery, but also leveraged throughout the Risk MAP program. The large volume of data resulting from Large Scale Automated Engineering or Base Level Engineering may be able to be used for the eventual production of regulatory and flood risk products, outreach and risk communication, and MT-1 processing.\r\n \r\n \r\n \r\n \r\n 20231018\r\n \r\n \r\n \r\n MIP Submission Date\r\n \r\n \r\n In work\r\n Unknown\r\n \r\n \r\n \r\n -119.598683\r\n -118.007726\r\n 45.929864\r\n 45.164329\r\n \r\n \r\n \r\n \r\n ISO 19115 Topic Category\r\n environment\r\n inlandWaters\r\n \r\n \r\n FEMA NFIP Topic Category\r\n Hydrology\r\n Flood Insurance Rate Map\r\n FIRM\r\n Flood Hazard Data\r\n 0.2-Percent-Annual-Chance Flood\r\n 10-Percent-Annual-Chance Flood\r\n 1-Percent-Annual-Chance Flood\r\n 2-Percent-Annual-Chance Flood\r\n 4-Percent-Annual-Chance Flood\r\n 1-Percent-Plus-Annual-Chance Flood\r\n 1-Percent-Minus-Annual-Chance Flood\r\n\t\t20-Percent-Annual-Chance Flood\r\n\t\t50-Percent-Annual-Chance Flood\r\n Channel\r\n\t\tHydrograph\r\n\t\tRegression Equation\r\n Node\r\n\t\tStream\r\n\t\tWater Body\r\n\t\tWatershed/Basin\r\n\t\tHydrologic Reach\r\n \r\n \r\n None\r\n REGION 10\r\n STATE OR\r\n COUNTY UMATILLA\r\n COUNTY-FIPS 41059\r\n COMMUNITY UMATILLA COUNTY\r\n FEMA-CID 410204\r\n\tCOMMUNITY UMATILLA COUNTY All Jurisdictions\r\n FEMA-CID 41059C\r\n COMMUNITY CITY OF ECHO\r\n FEMA-CID 410207\r\n COMMUNITY CITY OF HERMISTON\r\n FEMA-CID 410209\r\n\tCOMMUNITY CITY OF PENDLETON\r\n FEMA-CID 410211\r\n\tCOMMUNITY CITY OF STANFIELD\r\n FEMA-CID 410213\r\n\tCOMMUNITY CITY OF UMATILLA\r\n FEMA-CID 410214\r\n\tCOMMUNITY UMATILLA INDIAN RESERVATION\r\n FEMA-CID 410012\r\n HYDROLOGIC UNIT 17070103\r\n \r\n \r\n None\r\n Acknowledgment of FEMA would be appreciated in products derived from these data. These digital data are produced for the purposes of updating/creating a FIRM Database and/or Flood Risk Products.\r\n Original data development environment may vary. Finishing of the data is done using Esri?s ArcGIS software. The submitted geodatabase was created using ArcGIS version 10.5. The hydrologic modeling was performed using HEC-SSP.\r\n \r\n \r\n \r\n The FIRM Database consists of vector files and associated attributes produced in conjunction with the hardcopy FEMA FIRM. The published effective FIRM and FIRM Database are issued as the official designation of the SFHAs. As such they are adopted by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions exist in the regulations for public review, appeals and corrections of the flood risk information shown to better match real world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain boundaries is possible. Details of FEMA?s requirements for the FISs and flood mapping process that produces these data are available in the Guidelines and Standards for Flood Risk Analysis and Mapping. Attribute accuracy was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic system.\r\n\t Independent quality control testing of the FIRM Database was also performed.\r\n \r\n Proven hydrologic methods and/or FEMA approved models are used to compute flows at different locations and for different recurrence intervals (e.g., 1-percent-annual-chance [100-year] event, the 10-percent-annual-chance [10-year], 4-percent-annual-chance [25-year], 2-percent-annual-chance [50-year], and 0.2-percent-annual-chance [500-year] event). Computed flows are compared with historic data and flows established in previous hydrologic investigations to ensure reasonableness. Flows at the confluences are checked for the possibility of coincident peaks. Flows exiting the system and regulated by dams are carefully analyzed. At a given location flows for longer recurrence intervals are larger.\r\n Flows are computed at different locations of the study area. The method(s) and/or model(s) are described in the FIS Report. Assumptions and special considerations are also clearly stated in the report. Flows previously determined in other studies or hydrologic investigations are used for comparison. Computed flows are compared with historic flooding data. Submittal of hydrologic data in accordance with FEMA?s Data Capture Technical Reference ensures completeness of the Hydrology Study submittal.\r\n \r\n \r\n The FIRM Database consists of vector files and associated attributes produced in conjunction with the hardcopy FEMA FIRM.
