Advance registration required.  Session 1: Mitigating LA’s Natural Disasters with Smart Landscape Choices. 10:30 am- noon.  Seemingly unstoppable fires raged throughout the west in 2017, and California counted heavy losses in lives and property. Attendees will learn what combustible, invasive plant life to avoid, which plants have protective qualities, and which design strategies best protect homes.  Session 2: From Tragedy of the Commons to Uncommon Fortune. 1–2:30pm.  Our minds often skip over the spaces between our public buildings and our roads, be they expanses of turf grass, weed-filled or paved medians. These places can be harnessed to increase LA’s resilience, mitigating our fire, flood and slide danger, and also increasing our neighborhoods’ social capital and home values. Learn how to transform the tragedy of the commons into a powerful tool for building your neighborhood’s fortune. Attendees will learn about the processes, people and resources it takes to transform community space, and the various models that have led to success.
