Print this page FEMA's Flood Maps (FIRM) - Understanding and Utilizing This Resource

Course Outline
Depicting a parcel's flood zone is often required on surveys and development plans, and the feasibility of development with attendant costs as well as insurance requirements and premiums depend on a correct determination of the flood zone for any parcel of land with its present or proposed improvements.
While Flood Maps
are in regular use by a wide variety of users, many do not fully comprehend
the uses and limitations of this resource, and they may inadvertently misuse
or misunderstand the data portrayed on Flood Maps. The glut of similar terms
is confusing, and the format of FIRMs can vary. Where one flood study end-product
leaves off and another more accurate depiction takes over is not always clear
to the user.
A great deal can hinge on the correct identification and use of flood map data
and the accurate scaling of parcels overlaid on these maps, with the potential
for serious consequences when errors or misstatements are made.
This course is intended to bring understanding, eliminate confusion and equip
those who consult Flood Maps with confidence in their use and application of
Flood Map data.
This course includes
a multiple choice quiz at the end,
Learning Objective

Benefit to Attendees
Whether this course is the student's introduction to FEMA FIRMs or a study meant to broaden a current user's understanding, the FEMA FIRM tutorial is a well-crafted, thoughtful and delightfully presented educational experience that's sure to please while expanding professional capability and knowledge.
Through experiencing
this tutorial and completing the quiz, you'll gain a fuller understanding of
Flood Insurance Rate Maps (FIRMs) - their use, proper application and limitations.
Course
Instructor
Your instructor for this course is a Licensed Land Surveyor who's obtained professional registration in eight states and served as assistant construction superintendent, teacher, writer, civil technician, site planner, land surveying department head, plus created and managed the construction layout division of a large construction management firm, founded and operated a successful construction layout business and a separate land surveying business, and served as the employee of civil, surveying, and architectural firms, developers and state government. His career began in 1963.
The idea of assembling
this continuing education course came through experiencing the FEMA-FIRM tutorial
first-hand with a sincere desire to learn - and deriving both pleasure and significant
benefit from the exercise. I realized that others might enjoy it as much as
I did - and fulfill continuing education requirements in the process.
Course
Introduction
An old but never
outdated saying goes, "You get out of something what you put into it."
The centerpiece of this course is the FEMA-FIRM tutorial. It provides an opportunity
to learn and solidify understanding through well thought out and professionally
prepared graphics and a sensitive use of technology - combined to produce a
pleasant learning experience that's both efficient and effective.
The quiz questions are a vital part of your learning experience. They're designed
to reinforce the learning gained through the tutorial and to focus attention
on important points. The quiz is not separate from the course content or the
learning experience, but an integral part of it. This course was developed with
the hope you'll benefit from it as much as your instructor has through its creation.
It may be helpful
to realize that the tutorial is, among other things, a vocabulary lesson. A
wise person has said, "Classification is the key to learning."
FEMA loves abbreviations! They introduce terms or names and reduce them to abbreviations
in a flash: FEMA, FIRM, BFE, NFIP, FIS, SFHA, and on and on. May I suggest you
take the time to memorize the terms and abbreviations as they are introduced?
This will greatly aid in gaining the most from the material.
The tutorial also allows you to "look up" meanings through links and/or a glossary. More than most courses, this tutorial requires that you bite the bullet and fiercely determine that you WILL learn all these terms with their meanings. The greatest benefit will come from this approach.
I once read a book
on bee keeping. Throughout the book, the author used the word, "brood."
I kept reading, expecting to learn that word's meaning through the author's
usage. At the end of the book, I still didn't know what brood meant. That author
knew his material so well, he forgot to teach. There is a difference between
teaching and rambling. So many educators ramble. The FEMA FIRM tutorial does
not ramble; it teaches. But, as such, it requires that the student expend effort
to memorize the new terms as they're introduced. And, do use the links and glossary
frequently to discover or reinforce the meaning of any unfamiliar terms.
It's a great tutorial! I think you'll enjoy the time you spend with it and profit
from it, as I have.

Course SummaryThrough this course, you've learned how to get around in the Flood Map world and been introduced to the Flood Insurance Study Report (FIS) with its additional data, often useful to make an appropriate determination of whether or not a property is in a floodway, and you've learned how to estimate a Base Flood Elevation (BFE). In short, you've gained confidence in your use of a valuable resource.
Your course instructor has a suggestion for your consideration: If you are required to certify whether or not a property, portion of property or structure is in a Flood Insurance Risk Zone or a Floodway or otherwise assume the position of "knowing" exactly where a property is in relation to features or information shown on Flood Maps, I suggest you state as a part of that certification that your determination was made by scaling on a flood map in conformance with methods propagated and endorsed by FEMA at (link to their tutorial).
Those who make their living through measuring will readily see that the portion of the building and property shown in FEMA's tutorial to be in the Special Flood Hazard Area (SFHA) but NOT in the Floodway is mighty close to being in the Floodway or entirely out of both the Floodway AND the SFHA. The measurement methods illustrated in the tutorial (scaling from roads depicted on the Flood Map and from assessor's maps) leave a lot to be desired in the realm of accuracy.
I hope you've enjoyed the tutorial as much as I have and that the quiz has helped your retention of the information presented.
One final word:
The certificate offered at the end of the tutorial is, of course, not the PDHonline
certificate and does not provide continuing professional development credits.
But, it is very pretty!
