1263.610.  A public entity and the owner of property to be acquired

owner by an amount equal to or greater than the cost of such
relocation.
   (b) Carry out for the owner any work on property not taken,
including work on any structure, if the performance of the work is
likely to reduce the amount of compensation otherwise payable to the
owner by an amount equal to or greater than the cost of the work.
1263.620.  (a) Where summons is served during construction of an
improvement or installation of machinery or equipment on the property
taken or on the remainder if such property is part of a larger
parcel, and the owner of the property ceases the construction or
installation due to such service, the owner shall be compensated for
his expenses reasonably incurred for work necessary for either of the
following purposes:
   (1) To protect against the risk of injury to persons or to other
property created by the uncompleted improvement.
   (2) To protect the partially installed machinery or equipment from
damage, deterioration, or vandalism.
   (b) The compensation provided in this section is recoverable only
if the work was preceded by notice to the plaintiff except in the
case of an emergency.  The plaintiff may agree with the owner (1)
that the plaintiff will perform work necessary for the purposes of
this section or (2) as to the amount of compensation payable under
this section.
