Cal. Health and Safety Code § 25202.6

The owner of land subject to an easement, covenant, restriction, or servitude, required by the department pursuant to Section 25202.5, may make a written request of the department to remove the easement, covenant, restriction, or servitude. Upon receipt of such a request and supporting material, the department shall promptly review the need for the easement, covenant, restriction, or servitude and, when appropriate, and after a public hearing, shall agree to modify or remove the easement, covenant, restriction, or servitude to make certain that it continues to be no more restrictive than necessary to protect the public health and safety. When the department agrees to modify or remove such an easement, covenant, restriction, or servitude, the director and all of the owners of the land shall execute an instrument that reflects this agreement, shall particularly describe the real property affected by the instrument, and the owner shall record the instrument in the county in which the land is located within 10 days of the date of execution.
