Better understanding flood risk and mitigation

Picture
Better understanding and mitigating flood risk is the topic of Environmental Engineer and Consulting Hydrologist Bob Jacobson's zoom presentation to Louisiana Master Naturalists of Greater Baton Rouge in this video recorded on October 27, 2021.
The Zoom presentation is now up on the LMNA Channel at https://youtu.be/EHRg0abwXFw
Bob has Masters degrees in Environmental Policy (1981) and Environmental Engineering (1996 ) from LSU. Coping with climate change is a hot topic with a bearing on everyone's lives these days. In this video, Bob Jacobson frames the debate, clarifies the real likelihood of the "1 in a thousand-year flood" in human terms, spotlighting true mitigation, i.e. insuring for the dollar risk of flood events to allow the capacity to recover. He doesn't mince his words. Evacuation is the primary response to flood risk. Government evacuation orders are there to help save lives not real estate property, insure the property for your recovery.  Over the next decade we'll see major changes in the handling of risk and mortgages will include flood insurance. Levees and other engineering works should be regarded as insurance cost reduction measures, not hurricane protective measures.
​

Bob identifies and clarifies the five tenets of flood risk in dollar terms. Ri$k.

  • Tenet 1. Flood exposure is location specific
  • Tenet 2. Flood Hazard is a mathematical curve
  • Tenet 3. Flood risk is a present value
  • Tenet 4. Due diligence is fairly pricing risk
  • Tenet 5. Resiliency is good insurance + sensible mitigation Technology is making 21 Century wisdom a reality.


The principle of buyer beware applies to property and owners / prospective owners. We should apply due diligence. Insurance is our best way to mitigate flood risk to enable property recovery.

Owners must calculate their own flood risk, he says, and explains why the National Flood Insurance Program is not really fit for purpose. He asks the government to:
1. Adopt five tenets of 21st Century Flood Risk Wisdom. Educate officials, media and public to abandon foolish approaches. He says the National Flood Insurance Program (NFIP) is not supporting due diligence - please stop subsidizing excessive risk-taking, please stop over-pricing modest risk exposure. He says the NFIP is not supporting resiliency - there's a massive uninsured population, and damages are worsening with climate change and equity and justice issues are very apparent. We must try to be fair and avoid sub-optimal mitigation decisions.

2. Help modernize the Standard Operating Procedure for property transaction due diligence and support an online tool for pricing every property's flood risk. Accelerate our ability to accurately define the expected annual cost of flood risk for our property, the present value

3. Update 8 ultra-high resolution geospatial data

4.Continuously improve change forecasts

5.Properly regulate flood insurance markets

6. Broaden participation in good flood insurance No mortgaged property should be uninsured for the "30-year snake-eyes chance flood". He argues that flood risk is commonly underestimated, in a hypothetical family of 12 siblings, each living for 80 years, distributed widely, he says one of them has a 1 in 12 chance of experiencing a 1-chance-in-1,000-per-year-chance flood (snake-eyes).

7. Promote only sensible public projects and programs for mitigating flood risk. Don't waste tax dollars mitigating a flood risk that is cheaper for property owners to insure.

8. There are equity and justice issues regarding property, historically marginalized people may need assistance with their flood insurance.

​9. Promote no adverse impact on floodplain capacity flood storage and flood conveyance.
Don't increase flood risk pricing for other communities or neighbors (public & private projects). Don't place all burden on new development. Consider a uniform run-off tax. 
Drainage improvement and levees are useful. Also floodplain roads and bridges. Clearing ditches and culverts can help protect the lowest guy on the block.

10. Separate flood plain ecosystem restoration from sensible flood risk mitigation. They are both equally valid but distinct public objectives (by treating these separately you will likely get the best options for both goals). In Ecosystem restoration projects, please optimize for habitat In flood risk mitigation$ please optimize for flood insurance cost reduction and ensure that the insured owner beneficiaries contribute to the cost. ​

Our Origins: Acadiana Master Naturalists

​By Kyle Patton, Communications Chair
Picture


​  Stacey Scarce, the former Curator of the Acadiana Nature Station found out from Bob Thomas about the New Orleans chapter of master naturalists and the success of their first year.  In 2011, if I remember correctly, she recruited a few people from the Lafayette community to start a chapter in Acadiana.  The people I can remember include Jon Himel (a teacher at a local high school), Marty Floyd, an active Master Gardener named Stacy Lee and myself (Kyle Patton),. 


 There were about 10 other people at the first meeting, but they were not interested in going through the rigorous process of establishing and putting on the series of 10 workshops.  Over the first couple months, a few more people were recruited including Andre Daugereaux. 

​ We would meet once a month at the Nature Station to brainstorm about what would be needed to pull off a successful program.  It was decided that the first set of officers would be Stacey Scarce (President), Marty Floyd (VP), Jon Himel (Secretary), and myself as the Treasurer.  Jon started the paperwork to obtain 501c3 Non-Profit Organization Status.  We narrowed down the locations to 10 spread out around Acadiana and beyond.  From Rockefeller on the coast to the Arboretum in the north, we had a large diversity of programs (and still do).  
 
 The first Spring that we tried out the workshops we considered it a 'dry run' with board members being the first class.  I believe that was in the Spring of 2012.  We spent the next 6 months getting all of 'kinks' out as well as "crossing out 't's" and "dotting our 'i's".  The first official cohort was in the Spring of 2013 if my memory serves me correctly.  To date, we have had 8 cohorts from this program.

 My favorite thing about this program is its diversity of information spread across many unique locations.  The current locations for the workshops include:
the Acadiana Nature Station,
Vermilionville and the Jean Lafitte Center,
Avery Island,
the Louisiana Arboretum,
Allen Acres,
the Native Prairies of Eunice,
Rockefeller Wildlife Refuge,
UL's Ecology Center,
UL's Cade Farm,
Lake Martin and Henderson, and other locations that have rotated in and out of the program over the years.
