Final answer:
1) Building materials and construction techniques. The 2 key factors in rating Post-FIRM buildings are building materials and construction techniques and location and proximity to water bodies.
Step-by-step explanation:
The 2 key factors in rating Post-FIRM buildings are building materials and construction techniques and location and proximity to water bodies.
1) Building materials and construction techniques play a crucial role in determining the structural integrity and safety of a building. For example, a building made of high-quality materials and constructed using modern techniques will generally have a higher rating compared to one made of low-quality materials or outdated construction methods.
2) Location and proximity to water bodies also impact the rating of Post-FIRM buildings. Buildings situated in flood-prone areas or close to water bodies are more susceptible to water damage and can have a lower rating.
