About this Incubator Project

Resilient Management for Extreme Rain Events 
Please join us in further development of this pattern by providing constructive comments and feedback.
PLEASE NOTE: This pattern is a RELi Credit and will be referred to as ‘Credit’ in lieu of ‘Pattern’ for this Incubator project.

Incubator Project #C3RELiHA2-1 is focused on improving the RELi Resiliency Action List, Pilot Version Credit  “Reslient Management for Extreme Rain Events” (Hazard Adaptation + Mitigation HA Cr-2.1). The current language for the pattern  is posted below for reference.

The Resilient Management for Extreme Rain Events credit has been balloted and approved as part of the RELi Resiliency Standard as a “Credit.” Credits are considered menu item for the RELi Resiliency Standard. They are not required but they are available for  selection and pursuit by project teams.  The core elements of an approved credit cannot be substantively changed without re-balloting, but clarifications and modest amendments to the credit language are allowed. This incubator project intends to explore areas where metrics + techniques for the Resilient Management for Extreme Rain Events Credit can be clarified or the credit can be better defined without substantively changing the requirements.

Please post proposed comments or revisions in the Comments section of this blog post below OR Tweet comments that  include the project hashtag #C3pL. Tweets containing the #C3RELiHA2-1 #hashtag will appear in the Twitter Timeline included in this post (see below).

Possible Pattern (Credit) Improvements:

General: The RELi Resilient Management for Extreme Rain Events credit currently has a science driven metric that sets a sound direction for adapting to increasingly frequent and damaging extreme rain events.   However, it could be improved with added detail and clarity around the intent + measurable actions to be taken.

  • Better Clarify the baseline language in the credit body.
  • Identify the expectation of “Rainwater Managment”. Is this management equivalent to current expectations or can there be inconvenience or acceptable levels of minor damage resulting from an event? Are their metrics for inconveniences or acceptable minor damage?
  • Identify possible strategies for accomplishing this credit.

Current RELi Pattern (Credit) Language:

Name: Rainwater Management for Extreme Rain Events

Credit Purpose: Meet the 500 year flood plain criteria for requisite HA1 and provide for extreme rainwater events. Account for linear increases in extreme rain events over a 30 year period.

Credit Metrics + Criteria:

Base the increase on the Observed Change in Very Heavy Precipitation data available in the of the U.S. National Climate Assessment Report. Refer to figure  2.18.

Increase the amount of anticipated precipitation falling during a very heavy event by a factor  of 1.45* times the observed change that has occurred over the past 54 years between 1958 and 2012Refer to figure  2.18 Observed Change in Very Heavy Precipitation of the U.S. National Climate Assessment Report.

Example: Observed Change for the area comprised of Illinois, Indiana, Iowa,  Michigan, Minnesota, Ohio and Wisconsin is 37%. The recalibrated stormwater results would be: 37% X 1.45 = 54% increase.

*30 years is 0.45% of 54 years. The calculation assumes a linear increase in event strength.

Creating . Connecting . Curating

We humans have a critical connection to nature. Losing a species that lives in the wild can have dangerous consequences even for those who live in urban areas. An example of this would be the almost total disappearance of the vultures in India. In 1989, all but 1% of a native species of vultures had vanished due to a veterinary painkiller used on cows and buffalo. With India’s large Hindu population, cows and buffalo are used for work and dairy, but not often eaten. When they die, the animals are taken to “carcass dumps” across India.

These field “dumps” worked because, when vulture populations were large, they quickly stripped them to the bones. Vultures are living “environmental cleaners”. They have a digestive system with acids that neutralize most bacteria that causes a health hazard such as: anthrax, botulism, cholera and rabies, but this painkiller drug (still present in the carcasses) was lethal to them, even in small doses.

It took just a decade for the large vulture numbers to drop by over 98%. Without them, the carcasses rot in the fields, spread disease and contaminate water supplies. There are now 25 million feral dogs in India. More than half of the world’s deaths from rabies are occurring there due to these wild dogs and rats that are now eating the rotten flesh instead of the vultures.

Asian, US and European researchers worked for 10 years to find the problem’s source. Finally a group from Pakistan proved conclusively that the drug was lethal to the vultures. After a campaign to stop the drug, the Indian Government banned its use in animals. Due to the expense, farmers continued to buy it on the black market until the pharmaceutical company offered it’s replacement at cost.

There is a resilient solution to this serious problem. They are breeding and retraining the wild instincts of the vultures and for the first time in 20 years, their numbers are increasing. If support for these “environmental cleaners” continues to grow and the vulture population returns, the outcome could be a positive one. Nature can survive without us, but we cannot survive without it!

Pattern Name:
Reduced Eco-Exposure to Pharmaceuticals

Pattern Purpose:
Control the exposure of pharmaceuticals to the ecosystems + creatures to reduce unintended negative impacts and better maintain living system vitality.

Basic Pattern Metrics + Attributes:
1. Exercise use of the Precautionary Principle when developing + testing Pharmaceuticals.
2. Control exposure and release of Pharmaceuticals into the environment and living systems.
3. Monitor the use and impacts of Pharmaceuticals across their entire life cycle from cradle to grave.
