History of the Opinion in Oregon June 2009 Audobon Society of Portland, NWF, Northwest Environmental Defense Center, and AssociaCon of Northwest Steelheaders filed an ESA lawsuit against FEMA July 2010 FEMA entered into an agreement with the PlainCffs seIling the lawsuit, and requiring FEMA to iniCate formal consultaCon with NMFS February 2013 FEMA submits Program Level Biological Assessment for the NaConal Floodplain Insurance Program April 2016 NMFS releases Biological Opinion with Reasonable and Prudent AlternaCves June 2016 FEMA provides Community noCficaCon

Impacts to the Tualatin Basin?

Moving Forward DLCD Workgroups • – Mapping – Habitat Assessment and Mitigation – Regulatory – Local Permitting and Process Washington County: Washington County has been tracking • this topic for the past three years. Willamette Partnership: Working with Communities on • Smart Floodplain Management and an integrated approach to floodplain management. Others: Lawsuits •

Reasonable and Prudent Alternative #2 RPA 2A : Require development in SFHA be mitigated to achieve no • net loss of natural floodplain functions. RPA 2B : Identify a 170’ riparian buffer zone, limiting • development to select impacts RPA 2C: FEMA shall deny or decline to process requests for LOMR- • Fs that fail to show impacts were avoided or mitigated RPA 2D: FEMA shall review all CLOMR and CLOMR-Fs to determine • whether proposed project will adversely affect natural floodplain functions. RPA 2E: Track and report all permitted development activities and • mitigation as soon as practicable. RPA 2F: FEMA shall recommend that the State prioritize floodplain • development buyouts based on presence of high priority salmonid populations.

Reasonable and Prudent Alternative #3 - Mapping RPA 3A : Modify Flood Hazard Mapping Protocols • RPA 3B: Map Riverine Erosion Zones • RPA 3C: Depict the High Hazard Area on FIRMs • RPA 3D: Depict the area of future conditions flood hazard • RPA 3E : Revise Map Adoption Procedures • RPA 3F: Map residual flood hazards and risks behind levees • RPA 3G: Provide accurate maps based on the best available • data for all Oregon NFIP Communities
