What do severe storms and flooding mean for Pala?
Pala completed a Climate Change Vulnerability Assessment in 2019, which identified storms and flooding as one of four high-risk exposures resulting from climate change.
Key Facts about Storms and Flooding at Pala
Extreme rainfall events are becoming increasingly frequent and severe in the United States as a result of climate change. The EPA projects the number of 100-year floods in the contiguous United States to rise steadily for the remainder of the century under high emission scenarios.
In San Diego County, the drying that is projected with increased drought intensity and longer seasonal dry periods is offset with a projected increase in the wettest days. This means that storms will be less frequent and occasionally stronger. Greater drought conditions and lower soil moisture lead to flash floods along rivers and creeks in inland areas, as well as mudslides and landslides, especially in areas recently affected by wildfire. By 2100, CDPH predicts that 40% more land in San Diego County will become vulnerable to 100 and/or 500-year flood events.
Flooding events are common at Pala and associated with water drainage problems on the Reservation. Major events in 1998, 2005, 2010, and 2017 flooded Pala’s roads, damaged property, and trapped residents. Strong wind events and thunderstorms are also a noted hazard at Pala. Storms and flooding are known to trigger secondary exposures such as worsened air quality (indoor mold), water insecurity, and vector changes (e.g. mosquitos).
Pala’s High-Risk Health Impacts
Did you know that storms and flooding can harm our physical, emotional, spiritual and cultural health and wellbeing? Below are health impacts considered high or medium risk for residents of Pala.
- Storm and flooding-related injury and death
- Illness due to inability to access critical health services (from damage to roads, power, telecommunications, hospitals)
- Carbon monoxide poisoning (e.g. from generators during a power outage)
- Mental health impacts including post-traumatic stress, depression, anxiety, and grief
- Infections due to contact or ingestion of pathogens in contaminated water
- Drinking water supply interruption
- Short or long-term relocation
- Lost work, school, or business days
- Illness due to mold infestation
- Illness and death caused the West Nile Virus and Zika
Tips for Staying Safe During Storms and Flooding
- Follow directions from local officials regarding evacuation, shelters and safe drinking water advisories

What Is Pala Doing to Adapt and Prepare?
Pala completed an Adaptation Plan with a full list of strategies to help safeguard the health and wellbeing of the Pala community. Below are a few examples of ways we plan to address wildfire threats.
- Develop tribal transportation resilience plan to evaluate, strengthen and expand infrastructure (roads, bridges, etc.) and systems (transit)
- Install, re-engineer or conduct preventative maintenance on retaining walls, drainage systems, water storage tanks, stormwater retention basins, culverts, storm systems, porous surfaces, etc.
- Increase urban forestry, tree, landscapes and other green infrastructure to reduce stormwater runoff and increase heat resilience and increase tree canopy. Expansion and management of Pala’s natural infrastructure such as healthy watersheds and soils can build local resilience by improving soil water-holding capacity and reducing flooding and erosion.
