12. Emergency Preparedness - Flood-Prone Zones

Locate buildings out of flood-prone areas

Rationale: Locating facilities out of flood-prone zones and managing for potential flood risks decreases the immediate risk of mortality, injury, and PTSD from flooding and mitigates the longer-term risk of degraded indoor air quality from water damage, which is linked to chronic respiratory conditions and contagious diseases.

For the most accurate strategy and documentation requirements, please refer to the digital scorecard made available on the Fitwel Platform.

Requirements

Demonstrate compliance with one of the options below:

Option 1 - Flood-Prone Areas (Full Credit):

Demonstrate compliance with all the following requirements:

Low-Rise Residential with shared interior spaces (LR+), Low-Rise Residential with no shared interior spaces (LR)

1. Identify the flood risks within the project according to local flood risk maps.

2. Locate all buildings within the project outside of flood-prone areas*.

   *Flood-prone areas are those that are likely to flood over the next 30 years (> 6% chance of 1 inch of water reaching the largest home or building on a property at least once during this time period). 

   *Flood-prone areas are those that are at risk of coastal flooding, heavy rains, and poor drainage. 

Option 2 - Flood-Risk Mitigation (Full Credit):

The project may achieve partial credit by demonstrating compliance with all of the following requirements:    

Low-Rise Residential with shared interior spaces (LR+), Low-Rise Residential with no shared interior spaces (LR)

1. Identify the flood risks according to local flood risk maps within the project.
2. Implement a minimum of two of the following qualifying flood-risk mitigation practices for each building within the project:
   • elevate boilers so they are not located at or below ground level
   • install a sewage water backstop
   • improve lot grading so that stormwater runs away from the building by building up any sunken areas around the foundation or digging small depressions to properly channel water
   • integrate stormwater management strategies into landscaping through rain gardens, vegetated swales, or pervious pavements
   • install a rain barrel
   • develop a maintenance plan for gutters, downspouts, and splash pads so that rainwater from the roof flows easily away from the building
   • anchor outdoor fuel tanks
   • elevate utilities and service equipment so that they are a minimum of 1 foot above the flood elevation.
