72B. For the purpose of promoting health, safety, morals
and the general welfare of the community, the County Com-
missioners of Baltimore County are hereby empowered to reg-

ber of stories and size of buildings and other structures, the
percentage of lot that may be occupied, the size of yards,
courts, the set-back or distance of any buildings or structure
from front or side lot, road, street or alley line and other open
spaces, the density of population and the location and use of
buildings, structures and land for trade, industry, residence
or other purposes. Such regulations shall be made in accord-

to recommend the boundaries of the proposed districts, and
the regulations to be enforced therein. The Zoning Commis-

County Commissioners have received the final report, they
