county governing body has first approved such extension. Any ex-
tension requiring county governing body approval under this sub-

and sanitary sewerage construction programs with the other elements
of orderly growth in the two Counties. The two Commissions, the
County Council and the Board of County Commissioners are en-

discussion and work sessions, and between or among themselves,
as applicable, exchange such information and details as may be
necessary to achieve the coordination contemplated by this Section
of the capital improvement program, and the Commission shall give
to the county governing bodies such additional information and
details, either orally or in writing, as those bodies may request in
connection with their considerations of the capital improvements
program.

Section 83-96(71-45), as last repealed and re-enacted, with amend-
