All required subdivision improvements shall be installed by the
subdivider at his cost. In cases where, in accordance with other provisions of the Code,
the specifications for water and sewer utilities improvements are established partly to
provide for the eventual connection of other adjacent or abutting properties in a
coordinated manner, the subdivider may be eligible for certain credits or cost-share
programs which must be entered into by formal agreement, acceptable as to content and form
by the county attorney, prior to final plat approval or earlier, if so required by other
provisions of this code.
Where specifications for certain improvements have been
established by a governmental agency for streets, curbs, water, sewage, drainage or other
public improvement, such specifications shall be followed unless this chapter or other
provisions of the Code prescribe a more stringent standard.
