and the location of buildings designed for specific uses, and for
said purposes, to divide the City into districts and to prescribe
for each such district the trades and industries that shall be permitted,

may not be erected or altered. Such regulations are designed to promote
the public health, safety and general welfare and are made with reasonable

its peculiar suitability for particular uses, the conservation of
property values and the direction of building development, in accord
with a well-considered plan.
