A comprehensive Zoning Plan is hereby established for
the area of the Town of Boston, by dividing the territory thereof into certain
districts and prescribing regulations for buildings or other structures and
the use of the land therein. The comprehensive Zoning Law set forth in the
text and map which constitute this chapter is adopted pursuant to § 261
of the Town Law in order to promote and protect public health, safety, comfort,
convenience, prosperity and other aspects of the general welfare. These general
goals include, among others, the following specific purposes: to provide adequate
light, air and convenience of access to prevent undue concentration of populations
and overcrowding of land; to lessen congestion in the streets; to secure safety
from fire, flood, panic and other dangers; to enhance the environment by the
conservation of certain open land areas with certain desirable or unique characteristics
worthy of preservation; to facilitate the adequate provision of transportation,
water, sewerage, schools, parks and other public requirements; and to preserve
and promote the attractiveness and aesthetic value of the community.
