or land. All such regulations shall be uniform for each class
or kind of buildings throughout each district, but the regu-
lations in one district may differ from those in other districts.

3. Purposes—Such regulations shall be made in accordance
with a comprehensive plan and designed to lessen congestion
in the streets; to secure safety from fire, panic, and other
dangers; to promote health and the general welfare; to pro-
vide adequate light and air; to prevent the overcrowding of
land; to avoid undue concentration of population; to facilitate
the adequate provision of transportation, water, sewerage,
schools, parks, and other public requirements. Such regula-
tions shall be made with reasonable consideration, among
other things, to the character of the district and its peculiar
suitability for particular uses, and with a view to conserving
the value of buildings and encouraging the most appropriate
use of land throughout such municipality.

4. Method of Procedure—The Legislative body of such
municipality shall provide for the manner in which such
regulations and restrictions and the boundaries of such dis-
tricts shall be determined, established, and enforced, and from
time to time amended, supplemented, or changed. However,
no such regulation, restriction, or boundary shall become
effective until after a public hearing in relation thereto, at
which parties in interest and citizens shall have an oppor-
tunity to be heard. At least 15 days' notice of the time and
place of such hearing shall be published in an official paper,
or a paper of general circulation, in such municipality.

5. Changes—Such regulations, restrictions and boundaries
may from time to time be amended, supplemented, changed,
modified, or repealed. In case, however, of a protest against
such change, signed by the owners of 20 per cent or more
either of the area of the lots included in such proposed change,
or of those immediately adjacent in the rear thereof extend-
ing 100 feet therefrom, or of those directly opposite thereto
extending 100 feet from the street frontage of such opposite
lots, such amendment shall not become effective except by the
favorable vote of three-fourths of all the members of the legis-
lative body of such municipality. The provisions of the
previous section relative to public hearings and official notice
shall apply equally to all changes or amendments.
