The commission shall make, adopt, and may publish a master plan

of the municipality, and of the unincorporated area of the county,

for the purpose of bringing about a coordinated physical development

in accordance with the present and future needs of such area. The

master plan shall be developed so as to conserve the natural

resources of the area, to insure efficient expenditure of public

funds, and to promote the health, safety, convenience, prosperity,

and general welfare of the people of the area and the state. Such

master plan may include, among other things, studies and

recommendations relative to the location, character, and the extent

of highways, railroads, bus, streetcar and other transportation

routes, bridges, public buildings, schools, parks, parkways,

airports, forests, wildlife refuges, dams and projects affecting the

conservation of natural resources, and studies and recommendations

for an annual budget and long-range financial program for public

improvements. The commission may also perform in the area any

additional urban planning which is needed, including but not limited

to surveys, land use studies, urban renewal plans, technical

services, and other planning work. The commission may adopt the

master plan in whole or part, and subsequently amend or extend the

adopted plan or portions thereof. Before the adoption, amendment,

or extension of the plan or portions thereof, the commission shall

hold at least one public hearing thereon. Such hearing may be

adjourned from time to time. The adoption of the plan or portions

thereof shall be by resolution carried by not less than the majority

of the full membership of the commission including the ex officio

members thereof. Before such master plan or part thereof shall have

the status of an official plan, it shall be submitted to and shall

have the approval of the council insofar as such plan affects the

area within the city limits of the municipality and shall have the

approval of the board of county commissioners, insofar as such plan

affects the unincorporated area of the county, as the case may be.

The council and/or board may approve the plan in whole or in part,

or return the plan or any portion thereof to the commission for

further consideration. Any part so approved shall immediately

become in full force and effect as to the area covered by the

approved portion of such plan. Should the council or board fail to

act upon such plan within forty-five (45) days from the date of its

submission by the commission, such plan shall be deemed to be

approved by said council or board. After the adoption of the master

plan, or part thereof, an attested copy shall be certified by the

commission and by the approving authority and shall be certified to

the county clerk of such county for safekeeping and as a public

record, and certified to the clerks of such incorporated areas as

may be covered or affected by the plan.
