Lesson 4: Local Input Critical to Map Accuracy
![Page 18: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/18.jpg)
Local Input Critical to Map Accuracy
Record Flood Tests 2003 DFIRM-95 Map Accuracy; Locals rely on earlier more accurate
FIRMs
Accuracy of DFIRMs is proportional to Local Input; DEM
Don’t be afraid to challenge Preliminary DFIRMs Aerial reconnaissance is critical – capture crest High water mark data – crucial Update FIRMs when better available data is
captured

Lesson 9: “Two Ears and One Mouth”
![Page 30: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/30.jpg)
“Two Ears and One Mouth”
Why Stakeholder Meetings are Important
Ask: If they are opposed… why? Document it!
This project Coordinate with local officials Take a more detailed look Compliance with NAI
![Page 31: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/31.jpg)
“Two Ears and One Mouth”
Ask - What is their experience? What did they observe in the project
area during the flood of record? Who do they know who would be able to
provide good information?Be Real – Think from their Perspective How would I respond? What would I want
to know? As an engineer – how can I communicate to those concerns?
![Page 32: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/32.jpg)
Lesson 10: Scoping the Scene
![Page 33: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/33.jpg)
Scoping the Scene
Why Site Visits are Important
But I can do it all from the office! Survey data Aerial photography, Site photography Digital elevation models Birds eye view Street view …what more do I need?
![Page 34: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/34.jpg)
Scoping the Scene
Technical benefits of a site visit “Ah-hah!” Moments Get intuitive sense for the answer
What obvious conclusions can be drawn about flooding areas, flow patterns, etc.?
Document areas of interest with photographs, notes
![Page 35: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/35.jpg)
The Link – Outreach and Site Visits
Learn local landmarks What public buildings are in the project area or
nearby? What businesses are in the project area or
nearby? What are the names/characteristics of features
that are a key part of the analysis (road crossings, railroads, underdrains)
When in town, touch base with stakeholders Let them know you are in town
![Page 36: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/36.jpg)

Lesson 11: Caring What You Know and Knowing That You Care
![Page 38: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/38.jpg)
Caring What You Know and Knowing That You Care
Crafting the Message
Re-State their concerns and how you have addressed them
![Page 39: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/39.jpg)
The Message
Remember what you are being judged against… the last big flood How do your design floods compare to
the flood of record in the project area? How can you use this to help them
understand the proposed project?
![Page 40: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/40.jpg)
The Message
Say what you know Engineers have a tendency to qualify
their answers to the point that they bring confusion and – in some instances – distrust (“he/she won’t give us a straight answer”)
The Mayor’s favorite part
![Page 41: FROM “YOU’RE DOING WHAT?” TO “OH, I SEE” Lessons from a Northern Indiana Community Roger Gage, CFM Rodney Renkenberger, PLS, CFM Trevor Timberlake, PE,](https://reader034.fdocuments.in/reader034/viewer/2022051516/56649e055503460f94af1dc9/html5/thumbnails/41.jpg)
Conclusions
Success is not by accident Prepare Remember what you can gain from a disaster
Opinions can change If you invest time If you communicate the message
