I Get To Do This!

Sometimes in this job, I get to do the coolest things.
I recently participated in a ribbon cutting ceremony in partnership with the University of Arkansas for Medical Sciences (UAMS). We unveiled ten campsites built to tackle a special challenge – taking care of medical patients undergoing long-term treatments in Little Rock, Arkansas. Check this local tv story out.

Levee Vegetation and Public Safety

June 11th, 2009

There is an Associated Press article out today that requires a direct response, because it is inaccurate in many ways. The article is about the Corps’ Levee Vegetation Policy, which has been in existence for decades.

First, let me just correct the record.

Error: The Corps ordered thousands of trees chopped down.

Fact: The Corps notifies levee project sponsors of operation and maintenance deficiencies, which may include vegetation, animal burrows, encroachments, and closure structures.  These deficiencies must be corrected to remain eligible in this voluntary program for federal rehabilitation and repair assistance following a flood. 

Error: The Corps “is on a mission to chop down every tree in the country that grows within 15 feet of a levee…..”

Fact: The mission of the Corps’ levee safety program is to make sure levee systems are reliable and do not present unacceptable risks to the public, property or the environment, with the emphasis on public safety.  The Corps has specific authorities for approximately 2,000 levees, or 14,000 miles across the country; not the 100,000 miles stated by the AP. 

Error: The anti-tree policy arose from criticism directed at the Corps after Katrina.

Fact: The Corps’ vegetation management standards are not new, and the Corps has considered them critical to flood damage reduction project reliability for decades. 

The bottom line is – Public safety is the number one priority of the Corps Levee Safety Program and the consequences of Operation and Maintenance issues, like having vegetation on levees, floodwalls or dams, go beyond the possibility of a breach or failure.  While vegetation and other encroachments can harm the structural integrity of the infrastructure, it can also obscure visibility for visual inspections, impede access for maintenance and inspection, and/or hinder emergency flood fighting operations. Operation and maintenance is a critical component to overall public safety.

I’ve seen levees with garages, storage sheds and pools built into them, and I’ve seen trees ripped out of a levee by flood waters.          

We’ve flood-fought levees where tree roots cause seepage through and under levees and where tree roots clogged critical drainage structures such as relief wells. We’ve even seen tree roots damage flood walls and steel sheet piling. Fortunately, we’ve been able to find these problems and intervene just in time with safety measures before the levee breaches but we must not rely on intervention, but provide greater reliability through well maintained infrastructure.

The bottom line with any levee system is that you are only as strong as your weakest link – so we must have clear policies and standards, which include vegetation management, consistently applied and enforced through continuous and periodic inspections and assessments.

The Corps’ policies on vegetation are based on available engineering and scientific data – and they have been validated with an Independent External Peer Review and Independent Technical Review.

Existing scientific literature doesn’t conclusively validate or invalidate our vegetation standards.  But we are looking into it – we are in the midst of a two-year research program to enable reassessment of our engineering-based understanding of the public safety consequences of vegetation on flood damage reduction projects.

Any change to current USACE vegetation management policy and standards will be based upon sound engineering and science, and will not adversely affect public safety – because that is our #1 priority.

Historically Black Colleges and Universities

Comments Off on Historically Black Colleges and Universities

I had the honor of representing USACE at an event for Historically Black Colleges and Universities (HBCU) and Minority Institutions at Howard University here in Washington, DC recently. They were honoring “top supporters” – organizations, agencies and companies that contribute significantly to HBCUs.
The way that we contribute is really interesting. We have a certain amount of money allocated to us each year that is specifically to use with educational facilities, to have them do research or design work, things like that for us. This challenges the students with real world experience, helps us to “build the bench” of the future engineer workforce, and helps us keep costs down, as well.
The Army aims to have 13 percent of that education money go to HBCUs. And even though they still have to compete to get it (we can’t set it aside for them, legally), we’ve already surpassed that goal.
Not only was USACE among the “top supporters,” but they put my picture on the cover of this month’s US Black Engineer magazine! (I thought it was going to be a small picture in the lower corner of the cover!!) Check it out by clicking here.

I’m really passionate about this effort, because it’s essential in building diversity in engineering, which I know will make us a better, stronger Corps of Engineers.
One other cool tid-bit I got from this event – did you know that Howard University was the first institution to offer an engineering degree to African Americans?
It was a GREAT day, indeed.
