In order to avail itself of the powers conferred by this

be known as the zoning commission to recommend the boundaries of the

various original districts and to recommend appropriate regulations

to be enforced therein. The commission shall make a preliminary

report and hold public hearings thereon before submitting its final

take action until it has received the final report of the

commission. Where a municipal planning commission already exists,

it shall be appointed as the zoning commission.
