Based on the given story, let's evaluate its tragedy and comedy degrees based on the specified criteria.

**Tragedy Degree:**

The story contains some elements of potential disruption and emotional setbacks, as the residents face the possibility of displacement and alteration of their community. However, it doesn't delve deeply into profound tragic events or strong emotional impacts. The overall tone is more focused on resolution and hope, rather than intense tragedy.

**Comedy Degree:**

The story ends on a positive, hopeful note with the community coming together to face challenges collectively. It conveys a sense of unity and progress, but it lacks strong comedic aspects or a deeply emotionally delightful and happy ending. The tone is optimistic rather than comedic.
