“Plaintiff must prove that Defendant had notice of the dangerous condition before the incident occurred. To prove that there was notice, Plaintiff must prove: That Defendant knew of the condition and knew or should have known that it was dangerous. A public entity knows of a dangerous condition if an employee knows of the condition and reasonably should have informed the entity about it; or, That the condition had existed for enough time before the incident and was so obvious that the Defendant reasonably should have discovered the condition and known that it was dangerous.”
