SUBJECT: Common Deficiencies in the Presentation of Flood Insurance Studies

The following is a list of common errors and deficiencies that have been dis-
covered during the review of Flood Insurance Studies recently submitted to
FlA. This list represents items most commonly noted by the Technical Evaluation
Contractors (TECs) in the Review Comments, and additional data that is currently
being requested by the TEes so that all published Flood Insurance Studies
meet current FIA guidelines and specifications.

I. Narrative

A.

Section 1.2: This section was not meant to be a discussion of
the sources of information used. Include contacts (particularly
contacts with the community) made for purposes of coordination
of information, study methods, etcetera. Also, when available,
provide the date of, the organizations represented at, the
outcome of, and any changes made as a result of the final CCO
meeting.

v'

B. Section 2.1: This section should include justification and
approval for areas not studied by detailed methods. This
usually includes a statement of the criteria used to determine
which areas were to be studied and by which method, and an
indication of approval by the community and FlA. The criteria
used in most cases are current and projected development.

Identify all areas excluded from study and coordinate these
areas with the Vicinity Map and FIRM!FBFW maps.

,/

Also, indicate the specific future time period for which fore-
casted development was considered in determining which flooding
sources Were to be studied by detailed methods. For example,
do not use "...for the next 5 yearslli use "...until 1982."

C.

Section 2.2: Mention all surrounding communities and their
general location relative to the study area. You are requested
to include a brief discussion of each of the following natura:
features: topography, geomorphology, climatology, vegetation;
and soils. All of these factors affect runoff volumes and
flooding in the community.

D.

Section 2.3: This section should include estimates of the
frequency of, and damage caused by, significant past floods.
Also, indicate relationship of historic or significant past
floods to lOO-year flood.
