No plan shall be finally approved unless the streets shown on
such plan have been improved to a mud-free or otherwise permanently
passable condition or improved as may be required by this chapter
and any walkways, curbs, gutters, streetlights, fire hydrants, shade
trees, water mains, sanitary sewers, storm drains and other improvements
as may be required by this chapter have been installed in accordance
with this chapter.
In the event that any improvements which may be required have
not been installed as provided in this chapter or in accord with the
approved final plan, the Supervisors are hereby granted the power
to draw upon financial security by appropriate legal and equitable
remedies. If proceeds of such bond or other security are insufficient
to pay the cost of installing or making repairs or corrections to
all the improvements covered by said security, the Supervisors may,
at their option, install part of such improvements in all or part
of the subdivision or land development and may institute appropriate
legal or equitable action to recover the moneys necessary to complete
the remainder of the improvements. All of the proceeds, whether resulting
from the security or from any legal or equitable action brought against
the developer, or both, shall be used solely for the installation
of the improvements covered by such security and not for any other
purpose.
