FIT ProposalApril 29, 2015 Overview of Proposed Work 1.New Levee & Dike Data Development Levee/dike centerlines Diking districts Areas protected by levees/dikes 2.Compilation of New and Existing Data New statewide geodatabase to be published by DOGAMI and hosted on Oregon Geospatial Data Library

FIT ProposalApril 29, 2015 Definitions (for our purposes) Levee: A structure built and engineered for the purpose of preventing or controlling flooding of areas adjacent to flood-prone waterways. Dike: A feature that provides some level of flood control (often minimal) to areas adjacent to flood-prone waterways. Diking District: A taxing district that pools tax funds from property owners to maintain levees or dikes. Protected Area: An area behind a levee or dike that receives some level of protection during flood events.

FIT ProposalApril 29, 2015 Existing Levee & Dike Inventories 1.Estuarine Inventory (2011) Entire Oregon coastline and estuaries 2.Lower Columbia River Corridor (2012) From Pacific Ocean to Bonneville Dam Funded by Lower Columbia River Estuary Partnership DLCD’s Oregon Coastal Management Program

FIT ProposalApril 29, 2015 Proposed Study Area for Data Development

FIT ProposalApril 29, 2015 Proposed Data Development Methodology Levee/Dike Centerlines Geometry: Features will be located through visual analysis of lidar. Topo maps, soil maps, orthos, etc. will help. Locations will be vetted against local expertise and some field visits. Attributes: Will include type (man-made, natural, etc.), min and max elevations, adjacent water body, jurisdiction, hydrologic unit, manager, diking district, verification, and base image source. Diking Districts Geometry: Features will be mapped from assessor data. Visits to county offices will be needed to find diking district records. Attributes: Will include name, year established, status, contact information, etc. Protected Areas Geometry: Areas will be mapped by using lidar to delineate low-lying areas behind levees and dikes. Attributes: Will include tax lots, land ownership (private, state, etc.), acreage, jurisdiction, and hydrologic unit.

FIT ProposalApril 29, 2015 Proposed Deliverables 1.Levee and Dike Inventory Statewide Geodatabase Levee and dike centerline layer Diking district layer Protected areas layer Feature level-metadata (Oregon FIT compliant) Hosted on Oregon Geospatial Data Library 2.DOGAMI Publication Open-file report describing methodology and compilation Map plate of inventory coverage

FIT ProposalApril 29, 2015 Relationship to Oregon Framework Hazards FIT Levee/Dike element falls under the Hazards theme due to its close relationship to flood hazards Preparedness FIT Provides an authoritative dataset of known quality and completeness for the Preparedness Data Catalog Biosciences FIT Much like fish passage barriers (culverts, bridges, etc.) levees and dikes act as barriers to habitat, in this case off-channel wetlands

FIT ProposalApril 29, 2015 Expected Benefits Many More Features Identified USACE’s National Levee Database (the only data source available for areas without inventories) identifies ~25 features along the coast; OCMP’s inventory identifies ~2,000 features for same area. Important for Floodplain Management Many agencies have a need for knowing where flood control structures exist, including OWRD, DLCD, DOGAMI, USACE, FEMA, NRCS, National Weather Service. Important for Ecological Restoration Can help identify and prioritize restoration efforts to breach/remove levees and dikes to re-connect off- channel habitat for salmonids; helps DSL, ODFW, OWEB, watershed councils, BPA, NRCS, USFS, and BLM.

DOGAMI will expand the core study area to include optional priority areas, proportional to the amount received. For instance, if the full amount is received optional priority areas 1 and 2 will be added to the core study area.
