USACE LEVEE SAFETY PROGRAM
Levee Safety Program – Mission is to ensure levee systems provide benefits to the nation by working with sponsors and stakeholders to assess, communicate and manage flood risks to people, property and environment
Coordination with other Corps of Engineers Programs•Planning•Flood Risk Management (Silver Jackets, FPMS, etc.)•Civil Works Project Management (specific authorized projects)•Regulatory Program•Emergency Response•Missouri River Recovery Program•33 USC 408 Alterations•Dam Safety

RISK INFORMED DECISION MAKING5
Framework for decision making to inform actions related to levee systems
Transparent decisions under conditions of uncertainty
Levee system approach is primary to all activities
Levee segments and features are integral to excluding flood waters from the leveed area
SO WHAT IS RISK?6
FY18 LS ACTIVITIES• Routine Inspections – Federal and Non-Fed levees• Work by Other Reviews – technical review of project located w/in 300-500 ft of
levee centerline• Section 408 reviews• Periodic Inspections/SLRAs –
• Fairfax-Jersey Creek• Lawrence
• Periodic Inspections• Osawatomie• Auburndale • North Topeka• Soldier Creek RB2
• Communication of Risk information • Communicate to levee sponsors• Upload all levee system summaries and risk characterization into the NLD
• Support to other internal/external programs

LEVEE INVENTORY & REVIEW FACTS USACE has authorities (via WRRDA 2014) to
conduct ongoing levee inventory & one-time levee review on all non-federal levee systems
USACE has an approved FY 18 budget to conduct levee inventory & review for non-federal levee systems
NLD indicates over 8,000 levee systems (roughly 15,000 miles of levees) beyond USACE portfolio.

Presentation Notes
This is an effort to expand the national levee database to include all non federal levee systems, regardless of who owns them. Right now the nld only includes USACE program levees. There are two parts. Ongoing inventory effort and one time review (inspection and risk assessment).

Presentation Notes
Where do we start? This is what we know and what we don’t. The top three boxes are all levees in Corps programs. Either federally built or nonfederally built and in our rehabilitation program. The bottom two boxes are what this effort is focusing on. The 15,000 number comes from the FEMA Midterm Levee Inventory effort (or MLI data). This was FEMAs first crack at trying to identify unknown levees. It was a desktop review or several data inputs, (lidar, topo maps etc). It was intended to put out a wide net and capture anything that could be a levee. This data has not been vetted and is several years old at this point. With this effort we would review and refine that data. We would also want to include any levees that the states know of that are not included in the MLI list. The success of the last box would depend on how much the states know and their participation in inventory. This effort is focused on all non federal levees. The levees included are a mixed bag of privately owned, city owned, drainage dostrict owned, and even orphaned.
LEVEE INVENTORY & REVIEW - KEY ACTIVITIES
Locate: Upload basic information for all known levees in the National Levee Database
Inspect: Assess the condition of the nation’s levees by conducting field inspections
Characterize: Conduct levee risk assessments to evaluate and communicate the nature of flood risk posed
Share information. Develop a levee system summary

Presentation Notes
All work efforts associated with the inventory & review of our nation’s levees fit within the risk framework where we strive to make risk-informed decisions through RA/RM/RC activities. USACE has moved to risk informed decision making on their portfolio Locate: Inventory Inspect: boots on the ground, USACE levee inspection system Characterize: Screening level risk Assessment. Characterize the “risk”. Risk is three parts Share information on the NLD to better inform the public. Risk characterization summary would be public info. Transparency is often the key to action. We want people behind the levee to know their risk and get involved with decision makers in ways to reduce risk.

Presentation Notes
Levee Summary page included description, owner/operator/sponsor, the last inspection rating. Population and structures in leveed area. (was the FEMA HAZUS database, recently switched to the National Structures Inventory) During a levee screening this information is reviewed by an economist. The NLD will pull the updated info out of the LST and use that. Every levee should have an Levee Safety Action Classification (LSAC) and a Risk Characterization Summary that helps explain the LSAC and communicates what the significant risk drivers are.

The plan is for this to be a multi year effort, but funding comes year by year. We currently have funding for this year. Still unknown for next year. This is the ideal plan for the rest of this year.
