[GS] District/building to natural disaster prevention

[Horllthanael]

I come to you because,I have tries to create by own way, but i'm not a modmaker and i don't understand how to applies natural immunities grants by governor or leader, to a building.

but i have think a lot about it and i see to different version :
the easy solution will be a building grant the "Reinforced Materials" properties from "Liang" governor, to the city.
Maybe with a maintenance cost proportional to the number of citizen of the city ?

or a new district : Natural disaster center unlock at Astrology technology
with building to prevent, volcano eruption, tornado, forest fire, solar flare etc .. (building from different era) grant the immunity to citizen, building then improvement, without loss of yield modification (or reduction like from
maybe the in the following order :

• Floods, no need because there is the dam district
  
• Droughts, a building unlock with Irrigation technology
  
• Storms, separated into 4 different categories:
  • Tornadoes, a building unlock with Steam Power technology
    
  • Blizzards, a building unlock with Satellites technology
    
  • Sand storms, a building unlock with Astronomy technology
    
  • Hurricanes, a building unlock with Radio technology
• Forest Fires, a building unlock with Military Engineering technology
• Volcanic eruptions, a building unlock with Masonry technology to protect citizen,Construction to protect destruction and Replaceable Parts to protect form pillaged
  
• Meteor Showers, a building unlock with Lasers technology
• Solar Flares, a building unlock with Stealth Technology technology

the technology to unlock are just an idea, with just a mod grant a building i will be so thankful
just because i think that mechanism is a lack from the GS and natural disaster. Maybe in case of a district, a spy can Sabotage the district, cancelling the protection.
So if someone can create such mod it will be great.
