Risk Map Project Quarterly Report for Lower Boise (Canyon County), Idaho - April 27, 2018

This status update will specifically address work performed in the Canyon County, Idaho portion of the Lower Boise Watershed project.  If you would like to receive status updates for work performed in the Ada County, Idaho portion of the Lower Boise Watershed project, please make a request to RXProjectUpdates@starr-team.com.   

Project History
The State of Idaho identified the Lower Boise Watershed as a priority for FEMA's Risk MAP program.  The State determines its priorities based on population at risk to hazards, recent events, and community interest.  FEMA, State, and Local stakeholders participated in Risk MAP Discovery Meetings held on June 7 and 8, 2011 where community concerns were identified.  These concerns were captured in the Risk MAP Discovery Report and delivered to the communities in the watershed.  After the Discovery Meetings, community concerns were researched and analyzed, in order to develop a scope of work that includes updates to the communities' regulatory flood maps and Multi-hazard Risk Assessments based on community-identified resilience needs.  Multiple partners are involved in this effort.  U.S. Army Corps of Engineers – Walla Walla District is primarily responsible for Engineering, STARR II is primarily responsible for updates to the regulatory flood maps, and University of Idaho is primarily responsible for Risk Assessments.

Recent Activity
The original statutory 90-day appeal, which was initiated on the second newspaper publication, May 17, 2017, ended August 14, 2017.  FEMA did receive some comments with supporting data.  FEMA sent comment acknowledgement letters recently to affected communities.


It was discovered that the City of Star, a dual-county community, was not included in the original statutory 90-day appeal period for the incorporated areas within Canyon County.  In order to provide due process to all impacted communities, a second statutory 90-day appeal period is being initiated for the City of Star within Canyon County only.  That process is underway with the expectation that the new appeal period will begin on May 9th, following the second publication date in the local newspaper. 

Next Steps
STAR II will review and resolve any comments/appeals received from the City of Star (Canyon County).


FEMA will send your community the Letter of Final Determination (LFD) to formally notify you of the final flood hazard determination.  We anticipate that the Canyon County LFD will occur this fall and the Ada County LFD will occur spring 2019.  The final notice for FHDs will be published in the Federal Register after issuance of the LFDs.

The effective date for the project will be six months after the LFD issue date.  Communities must adopt a compliant floodplain management ordinance by the maps’ effective date in order to remain participants in good standing in the National Flood Insurance Program (NFIP).

FEMA held a resilience meeting with Canyon County on Nov. 29, 2017. The resilience meeting included information about risk to multiple hazards and focused on future mitigation and planning opportunities. The final materials have been developed for the resilience phase. Links to all of the documents, presentations, and map viewer can be found below:
