In no event shall the city be liable in, damages for an injury to person, a damage to property, or a death, caused by a defect or a dangerous condition in a public thoroughfare, site, or facility, unless the city has had actual notice prior to the injury, damage, or death that the defect or condition existed and has had a reasonable time thereafter in which to repair or remove it.
No action shall be maintained against the city for damages growing out of such injury, damage, or death unless the claimant first gives written notice to the council within 30 days after the injury, damage, or death is sustained, stating specifically the time when, the place where, and the circumstances under which it was sustained, and that said person will claim damages therefor of the city in an amount which said person specifies, but in no event shall the action be started until 30 days have elapsed after the presentation of such notice to the council.
