What We’ll Talk About Today
• Overview of KDOW CTP Activities
• Dam Safety Hazard Mitigation

How it started
What’s involved
Automated Tools and Processes
Review of Products
FEMA Risk MAP Applications
• Q&A
KDOW CTP Activities
• Consideration of Risk MAP into other watershed
based initiatives (dam safety, non-point source,
TMDLs, etc.)
• Collected LIDAR in approximately 1/3 of state
• State lead agency for Silver Jackets
– Partner in 2 SJ pilot projects
• Involved in USGS FIMI projects
• Ongoing development of KY Risk Communication
Toolbox
KDOW Risk MAP Status??
• Add map with watersheds, projects completed to date?
• Watersheds account for approximately 55% of KY population
Collaboration Efforts
• KDOW Dam Safety partners with federal and state agencies
(NRCS, FEMA, KY Emergency Management):
–
–
–
–
Resource sharing (natural disaster/emergency response)
Provide staff to perform interagency permit reviews
Data sharing (LiDAR, base mapping) to support dam safety studies
Evaluation of prototype tools related to dam safety (beta tester -FEMA DS
GeoDamBREACH toolset)
– Evaluation and feedback on FEMA Risk Map Non-regulatory products
• Revised Dam Safety section of State Hazard Mitigation Plan
• Shift focus from regulatory-only to risk identification and
reduction
Dam Safety Hazard Mitigation Program
The purpose is to avoid situations
like this……..
Dam Safety Hazard Mitigation Program
• Purposes:
– To determine best practices to help quantify,
communicate, and mitigate current risks associated
with dams and help avoid future risks.
– Align products and processes to current Risk MAP
non-regulatory initiatives
– To develop a prioritized list of dams to support
KDOW’s planning for rehabilitation, repair, or study
needs
• Starting Point - Subset of 197 dams
– Dams are owned by state, local governments or NRCS
Initial Set of Dams in Program
Dam Safety Hazard Mitigation Program
Ongoing program involves:
•
•

•
Data Collection
Rapid Inundation Mapping
Field Reconnaissance
Preliminary Risk Screening
Simplified Emergency Action Plan Development
Seismic Assessment Reviews
Prototype Catastrophic Long Term Recovery Plans
Expanded Dam Owner Outreach

Expanded Dam Owner Outreach
Rapid Inundation Map
• Team using SMPDBK tool (NWS/NOAA)
– 2 part Arc-GIS based tool, using simplified dam break routines
• Team also testing FEMA Dam Safety toolset that
enhances the SMPDBK tool (GeoDamBREACH)
• Produces a rapid, preliminary dam breach/inundation
• Also produces depth grids
• Appropriate for Preliminary Risk Screenings
Inundation Map
Data Management Portal
• Developed by team to communicate and manage data/info
• Easier collaboration; coordination with KDOW’s Risk MAP
efforts/KyEM Portal
Preliminary Risk Screening
• Goal - establish a consistent/objective ranking of dams
• Various tools and procedures reviewed by team
• Semi-automated NRCS/USBR tool, combined with FEMA HAZUSMH to incorporate damages and PAR from dam breach
Dam Risk Mitigation Strategies
• Results of the risk screening being used to support a review of
potential mitigation options for dams.
• Mitigation could include:
– Structural upgrades to dam/spillways
– Acquisition of easements in downstream inundation areas
• Could be drainage/flowage easement
• Conservation easements
– Adoption of “higher standards” for floodplain/inundation area
development
– Buy-outs of affected property owners
– Flood proofing/elevation/relocation of structures
– Enhanced flood warning/evacuation systems and plans
– Establishment of downstream development regulations
Simplified Emergency Action Plans
• Goal – to produce a “starting point”, semi-automated
EAP document
• Product – Microsoft Word document with database
driven fields and other user input fields; inundation/
evacuation map included
• Team is testing/evaluating of FEMA Dam Safety toolset
that includes EAP (GeoDamBREACH)
Catastrophic Long Term Recovery Plans
• Goal – to produce a template Catastrophic Long Term
Recovery (CLTR) prototype for local dam owners and
local emergency management officials to reference for
specific dams
• CLTR Plan for dams – guidance on what to do and
how to recover impoundment and downstream assets
that are damaged or destroyed as a result of a dam
failure

Walks through the recovery steps necessary
Help identify potential funding sources
Aligned with Kentucky Emergency Management plans
• Incorporation into KyEM CHAMPS system
How does this tie into the Risk MAP process?
