Sources of Risk (i.e. Uncertainty)
Integrity - Competence - Service
“Transitional Infrastructure”
• Lifeplaces• Regulatory feasibility• Best engineering judgment• Institutional risk tolerance• Best available science
Integrity - Competence - Service
The Cheese…aka Opportunities….
• Visualize key environmental factors • Use a data set that is refreshed every morning• Bring data into any application• Make NEPA decisions earlier
•
Integrity - Competence - Service
Here kitty, kitty…
We used existing data sets:
• MaineDOT GIS Layers• MeGIS Layers• MDIF&W GIS• MEMA GIS
No data collection needed.

Rounding up the Mice…
• First it was ArcGIS Map• Then it was ArcGIS Pro Model
Builder• Soon, Python Code?

Challenges…
The data, in beta, is wrong. Errors are inherent in everything…the process is not static.
Discomfort with decision-making by “mindless” technology…Not a replacement for best professional judgment.
Setting priorities versus understanding risk. Down the risk ‘rabbit hole’…enter others’ priorities!

Q: What information is most important?
A: All mice are equal
But for now, we focus on environmentally-minded mice.

Headliners versus Understudies:Proxy Indicators
1. Is the drainage area part of a priority Atlantic salmon watershed? 2. Is the project located within a mapped buffer for habitat for a state
endangered, threatened, or special concern species?3. Is the feature a mapped stream barrier?4. Is the location identified as a large undeveloped habitat block connector?5. Is the existing structure > the calculated bank full width?6. What is the drainage area to (i.e. watershed size of) feature?7. Is the feature located within an identified FEMA 100-year floodway?8. Is the feature subject to coastal threats of sea level rise (SLR) and/or storm
surge (SS)? 9. What percentage of the drainage area to the feature is developed and/or
impervious?10. Is the road a sole access, hurricane evacuation route or emergency access for
emergency response vehicles?

Q4
USFWS, in conjunction with other non-government organizations, developed a GIS-data layer showing those
stream crossings that have the potential or have been observed to be barriers to aquatic species' movement up and downstream. Mapped barriers may be prioritized
for replacement.
Presence of GIS-mapped large undeveloped blocks of potential habitat on either side of a road increases the likelihood that terrestrial species will cross roads that
may otherwise serve as barriers to movement. Adjacent large habitat blocks may necessitate inclusion of wildlife
crossing structures in any reconstruction.

Is the drainage area part of a priority Atlantic salmon watershed?
The three Maine Atlantic salmon habitat recovery units (SHRUs) have been designated into "tiers" based on habitat value as determined by USFWS, NMFS, and Maine DMR. These designations relate to the Maine
Atlantic salmon Programmatic Consultation requirements for design and construction.
Presence of the habitat and/or any buffers critical to a lifestage of species listed under Maine's Endangered
Species Act identifies the potenial need for pre-construction surveys, passage modifications, or post-
construction monitoring that may need to be incorporated into project design.
Q1
StreamStats with MATS
[Span_Width]
StreamStats
budget, schedule Hebson
Maine's USFWS and USACE consider stream crossing structures with a span equal to or greater than 1.2 times
the stream bankfull width (1.2 x bfw) to be fully accessible for all aquatic species. Any crossing less that
1.2 x bfw may need to be upsized or pay in lieu fee mitigation depending on its location.

Bring on the cheese!!
Integrity - Competence - Service
• Unlike Mouse Trap, “board” is dynamic
• Accessible to all
• Inform, not decide
• Budgets & schedules look like certainty
• People matter
The cats, mice and cheese together create the risk…

Winning Support
At first they didn’t think it was worth it.Then curiosity attracted other cats.Then the mice were hard to find.
Then someone opened a trapped door and… TRAPPD disappeared!
What changed?
The mice got hard to find. The cat had to get creative. The cheese started to age.
Now it’s gourmet aged cheese made by feline monks!

What’s Next?
• Highways• Cross Culverts• Unstable slopes• MS4• Historical Sites• More?
…Once we find the other doors to the maze.
