Cal Civil Code § 1009. 
Public use of private lands; Dedication prerequisite to vested right; Offer to governmental entity; Vested right from governmental expenditure; Coastal property affected; Owners precluding evidence of implied dedication

   (a) The Legislature finds that:
 
   (1) It is in the best interests of the state to encourage owners of private real property to continue to make their lands available for public recreational use to supplement opportunities available on tax-supported publicly owned facilities.
 
   (2) Owners of private real property are confronted with the threat of loss of rights in their property if they allow or continue to allow members of the public to use, enjoy or pass over their property for recreational purposes.
 
   (3) The stability and marketability of record titles is clouded by such public use, thereby compelling the owner to exclude the public from his property.
 
   (b) Regardless of whether or not a private owner of real property has recorded a notice of consent to use of any particular property pursuant to Section 813 of the Civil Code or has posted signs on such property pursuant to Section 1008 of the Civil Code, except as otherwise provided in subdivision (d), no use of such property by the public after the effective date of this section shall ever ripen to confer upon the public or any governmental body or unit a vested right to continue to make such use permanently, in the absence of an express written irrevocable offer of dedication of such property to such use, made by the owner thereof in the manner prescribed in subdivision (c) of this section, which has been accepted by the county, city, or other public body to which the offer of dedication was made, in the manner set forth in subdivision (c).
 
   (c) In addition to any procedure authorized by law and not prohibited by this section, an irrevocable offer of dedication may be made in the manner prescribed in Section 7050 of the Government Code to any county, city, or other public body, and may be accepted or terminated, in the manner prescribed in that section, by the county board of supervisors in the case of an offer of dedication to a county, by the city council in the case of an offer of dedication to a city, or by the governing board of any other public body in the case of an offer of dedication to such body.
 
   (d) Where a governmental entity is using private lands by an expenditure of public funds on visible improvements on or across such lands or on the cleaning or maintenance related to the public use of such lands in such a manner so that the owner knows or should know that the public is making such use of his land, such use, including any public use reasonably related to the purposes of such improvement, in the absence of either express permission by the owner to continue such use or the taking by the owner of reasonable steps to enjoin, remove or prohibit such use, shall after five years ripen to confer upon the governmental entity a vested right to continue such use.
 
   (e) Subdivision (b) shall not apply to any coastal property which lies within 1,000 yards inland of the mean high tide line of the Pacific Ocean, and harbors, estuaries, bays and inlets thereof, but not including any property lying inland of the Carquinez Straits bridge, or between the mean high tide line and the nearest public road or highway, whichever distance is less.
 
   (f) No use, subsequent to the effective date of this section, by the public of property described in subdivision (e) shall constitute evidence or be admissible as evidence that the public or any governmental body or unit has any right in such property by implied dedication if the owner does any of the following actions:
 
   (1) Posts signs, as provided in Section 1008, and renews the same, if they are removed, at least once a year, or publishes annually, pursuant to Section 6066 of the Government Code, in a newspaper of general circulation in the county or counties in which the land is located, a statement describing the property and reading substantially as follows: "Right to pass by permission and subject to control of owner: Section 1008, Civil Code."
 
   (2) Records a notice as provided in Section 813.
 
   (3) Enters into a written agreement with any federal, state, or local agency providing for the public use of such land.
 
   After taking any of the actions set forth in paragraph (1), (2), or (3), and during the time such action is effective, the owner shall not prevent any public use which is appropriate under the permission granted pursuant to such paragraphs by physical obstruction, notice, or otherwise.
 
   (g) The permission for public use of real property referred to in subdivision (f) may be conditioned upon reasonable restrictions on the time, place, and manner of such public use, and no use in violation of such restrictions shall be considered public use for purposes of a finding of implied dedication.
