As used in this chapter:

For purposes of this chapter, seismic safety improvements or fire sprinkler improvements which are owned, built, controlled, operated, and maintained by the private owner of the building in which they are installed are not public property or property of a public entity solely because the improvements were financed, in whole or in part, by means of the formation of a special assessment district.

A condition is not a dangerous condition within the meaning of this chapter if the trial or appellate court, viewing the evidence most favorably to the plaintiff, determines as a matter of law that the risk created by the condition was of such a minor, trivial or insignificant nature in view of the surrounding circumstances that no reasonable person would conclude that the condition created a substantial risk of injury when such property or adjacent property was used with due care in a manner in which it was reasonably foreseeable that it would be used.

A condition is not a dangerous condition within the meaning of this chapter merely because of the failure to provide regulatory traffic control signals, stop signs, yield right-of-way signs, or speed restriction signs, as described by the Vehicle Code, or distinctive roadway markings as described in Section 21460 of the Vehicle Code.

Neither a public entity nor a public employee is liable under this chapter for an injury caused by the plan or design of a construction of, or an improvement to, public property where such plan or design has been approved in advance of the construction or improvement by the legislative body of the public entity or by some other body or employee exercising discretionary authority to give such approval or where such plan or design is prepared in conformity with standards previously so approved, if the trial or appellate court determines that there is any substantial evidence upon the basis of which (a) a reasonable public employee could have adopted the plan or design or the standards therefor or (b) a reasonable legislative body or other body or employee could have approved the plan or design or the standards therefor. Notwithstanding notice that constructed or improved public property may no longer be in conformity with a plan or design or a standard which reasonably could be approved by the legislative body or other body or employee, the immunity provided by this section shall continue for a reasonable period of time sufficient to permit the public entity to obtain funds for and carry out remedial work necessary to allow such public property to be in conformity with a plan or design approved by the legislative body of the public entity or other body or employee, or with a plan or design in conformity with a standard previously approved by such legislative body or other body or employee. In the event that the public entity is unable to remedy such public property because of practical impossibility or lack of sufficient funds, the immunity provided by this section shall remain so long as such public entity shall reasonably attempt to provide adequate warnings of the existence of the condition not conforming to the approved plan or design or to the approved standard. However, where a person fails to heed such warning or occupies public property despite such warning, such failure or occupation shall not in itself constitute an assumption of the risk of the danger indicated by the warning.

Neither a public entity nor a public employee is liable under this chapter for an injury caused by the failure to provide traffic or warning signals, signs, markings or devices described in the Vehicle Code. Nothing in this section exonerates a public entity or public employee from liability for injury proximately caused by such failure if a signal, sign, marking or device (other than one described in Section 830.4) was necessary to warn of a dangerous condition which endangered the safe movement of traffic and which would not be reasonably apparent to, and would not have been anticipated by, a person exercising due care.

Neither a public entity nor a public employee is liable for an injury caused by the operation or nonoperation of official traffic control signals when controlled by an emergency vehicle in accordance with the provisions of subdivision (a) of Section 25258 of the Vehicle Code.

Neither a public entity nor a public employee is liable for an injury caused by the effect on the use of streets and highways of weather conditions as such. Nothing in this section exonerates a public entity or public employee from liability for injury proximately caused by such effect if it would not be reasonably apparent to, and would not be anticipated by, a person exercising due care. For the purpose of this section, the effect on the use of streets and highways of weather conditions includes the effect of fog, wind, rain, flood, ice or snow but does not include physical damage to or deterioration of streets and highways resulting from weather conditions.

Neither a public entity nor a public employee is liable for an injury caused by a natural condition of any unimproved public property, including but not limited to any natural condition of any lake, stream, bay, river or beach.

Neither a public entity nor a public employee is liable for any injury occurring on account of the grading or the performance of other maintenance or repair on or reconstruction or replacement of any road which has not officially been accepted as a part of the road system under the jurisdiction of the public entity if the grading, maintenance, repair, or reconstruction or replacement is performed with reasonable care and leaves the road in no more dangerous or unsafe condition than it was before the work commenced. No act of grading, maintenance, repair, or reconstruction or replacement within the meaning of this section shall be deemed to give rise to any duty of the public entity to continue any grading, maintenance, repair, or reconstruction or replacement on any road not a part of the road system under the public entity’s jurisdiction. As used in this section “reconstruction or replacement” means reconstruction or replacement performed pursuant to Article 3 (commencing with Section 1160) of Chapter 4 of Division 2 of the Streets and Highways Code.

A public entity, public employee, or a grantor of a public easement to a public entity for any of the following purposes, is not liable for an injury caused by a condition of:

Neither the State nor an employee of the State is liable under this chapter for any injury caused by a condition of the unimproved and unoccupied portions of:

“Hazardous recreational activity” also means:

racing, off-road motorcycling or four-wheel driving of any kind, orienteering, pistol and rifle shooting, rock climbing, rocketeering, rodeo, self-contained underwater breathing apparatus (SCUBA) diving, spelunking, skydiving, sport parachuting, paragliding, body contact sports, surfing, trampolining, tree climbing, tree rope swinging, waterskiing, white water rafting, and windsurfing. For the purposes of this subdivision, “mountain bicycling” does not include riding a bicycle on paved pathways, roadways, or sidewalks. For the purpose of this paragraph, “body contact sports” means sports in which it is reasonably foreseeable that there will be rough bodily contact with one or more participants.

(A) Failure of the public entity or

employee to guard or warn of a known dangerous condition or of another hazardous recreational activity known to the public entity or employee that is not reasonably assumed by the participant as inherently a part of the hazardous recreational activity out of which the damage or injury arose.

(B) Damage or injury suffered in any case where permission to participate in the hazardous recreational activity was granted for a specific fee. For the purpose of this subparagraph, “specific fee” does not include a fee or consideration charged for a general purpose such as a general park admission charge, a vehicle entry or parking fee, or an administrative or group use application or permit fee, as distinguished from a specific fee charged for participation in the specific hazardous recreational activity out of which the damage or injury arose.

(C) Injury suffered to the extent proximately

caused by the negligent failure of the public entity or public employee to properly construct or maintain in good repair any structure, recreational equipment or machinery, or substantial work of improvement utilized in the hazardous recreational activity out of which the damage or injury arose.

(D) Damage or injury suffered in any case where the public entity or employee recklessly or with gross negligence promoted the participation in or observance of a hazardous recreational activity. For purposes of this subparagraph, promotional literature or a public announcement or advertisement that merely describes the available facilities and services on the property does not in itself constitute a reckless or grossly negligent promotion.

(E) An act of gross negligence by a public entity or a public employee that is the proximate cause of the injury.
