EVALUATION AND IMPLEMENTATION OF
URBAN DRAINAGE AND FLOOD CONTROL PROJECTS

Summary of Report

~

Drainage and flood control problems in an urban region are a direct
result of human interference with normal drainage patterns. In a growing
metropolitan area, the thrust of drainage solutions should be in two
basic directions, prevention and remedial works.
Preventive activities take the form of flood plain management to-
gether with good planning, As rural areas urbanize, flood plains can
be developed in such a manner so as to preclude or minimize future damages
and problems from flooding. Also, as urbanization proceeds, adequate
local drainage should be provided along with streets, roads, schools,
parks and other public facilities, consistent with wise levels of
public investment.
Situations that require remedial action are those where flood plains
have been improperly occupied and developed and where local drainage
problems have not been adequately considered and handled. In these
cases, positive steps are needed, usually by a public agency, to remove
the hazard or alleviate the inconvenience caused by flooding.
Drainage and flood control activities can be placed into structural
and non-structural categories. Structural activities incorporate both
preventive and remedial categories and include installation of storm
sewers, culverts, inlets, adequate curb and gutter, channelization and

detention facilities, Non-structural activities also overlap both pre-

ventive and remedial functions and include flood plain management

(preventive), flood plain warning (remedial), and flood insurance (remedial).
