A. INTRODUCTION

GENERAL

This manual was prepared by the St. Paul District. U.S. Army Corps of
Engineers. in cooperation with the Minnesota Department of Natural Resources.
for the Building Code Division of the Minnesota Department of Administration.
Significant contributions to the draft preparation and review were made by
Wehrman-Chapman Associated, Minneapolis, Minnesota, under contract, and by
the Pittsburg District, Corps of Engineers.

The Building Code Division has the responsibility for overall administration
of the State Building Code which became effective on July 1, 1972. In
January 1974 a model code entitled "Flood-Proofing Regulations" published
by the Corps of Engineers in June 1972 was adopted by reference, with minor
amendments. and incorporated into the State Buildin9 Code. The Corps model
code included performance standards which provide a basis for evaluating the
effectiveness of flood-proofing of individual structures.

This administrative manual is designed:

1) To provide administrative assistance to municipal building officials
in the implementation of flood-proofing provisions of the State
Building Code.

2) To serve as a guide to engineers, architects, builders, and others
involved in the planning. design, plan review. and construction of
flood-proofed structures in flood plain areas. and

3) To provide guidelines for administering flood-proofing regulations
as part of a comprehensive flood plain management program.

PRINCIPALS OF FLODD-PROOFING

Flood-proofing includes those methods of construction which. when applied to
structures or properties. will prevent or mitigate damage from floods.
Flood-proofing measures may be included in the design and construction of new
structures or in the modification of existing structures. They are categorized
in Section 301.3.8 of the Flood-Proofing Regulations as ermanent (requiring no
action at the time of flooding to put the measures into effect , contingent
or partial (requiring minimal pre-flood action). and emergency or temporary
(accomplished just prior to or during an actual flood). Typical flood-proofing
measures include the elevation of structures above flood levels. anchorage of
structures to resist flotation and horizontal displacement by floodwaters,
reinforcement of concrete and masonary walls and floors to resist water pressure.
