Mayor Mat Siscoe's home was also flooded, and he described the situation as "a lot of panic, followed by stages of grief" for residents.

Why this leaning score
The article's tone is generally sympathetic towards the residents affected by the flooding, using emotive language such as 'grief', 'shock', 'horrendous', and 'chaos' to describe their experiences. The language also frames the politicians' responses in a neutral manner, but Mayor Siscoe's comments are quoted at length, allowing his emotions and empathy to shine through.
