(a)
In a proceeding to vacate a street or highway, if the legislative body determines that the public convenience and necessity require the reservation and exception of easements and rights-of-way for works enumerated in Section 8340, such reservations and exceptions shall be recited in the resolution of vacation, in addition to any other matter required to be recited therein. The recital may describe the reservations and exceptions by reference to a precise map which is recorded or to which reference is made in the resolution and which is permanently maintained by the public entity.
(b)
Subsequent proceedings of the public entity in relation to the vacation, including a deed or conveyance of title to or an interest in the property, are subject to, and governed by, the reservations and exceptions recited in the resolution of vacation and the deed or conveyance shall contain a recital to that effect.
