The objectives in adopting and amending official maps shall be to:
(1) Protect private property rights and values;
(2) Provide a means by which private construction and development may anticipate highway location and relocation, and thus prevent the loss in property values and private investment that would otherwise result in uncoordinated public and private development;
(3) Avoid the waste of public funds resulting from relocation of unplanned highways or the maintenance of unneeded highways;
(4) Avoid the waste of public funds resulting from the condemnation of buildings and structures constructed without regard to planned highway construction; and
(5) Provide a means of coordination and cooperation between highway development and private development in order to reduce waste of physical, human, economic and financial resources.
