Relevant Options

Purchase backup generators for the water infrastructure system to provide a sustained minimal level of water services in the event of a catastrophic power loss. Increase adoption of distributed energy resources such as solar and wind by lowering financial and regulatory barriers to permitting and development. When installed with battery backup or emergency power Assess governmental assets' exposure to erosion, extreme heat, flooding, high winds, landslides, severe winter weather and wildfire. Determine if those assets house critical functions. If they do, determine
