Building Resilient,
Active, & Connected Communities

99NN is a 501(c)3 non-profit that supports neighborhoods to be climate-ready and connected through community mapping, local storytelling, and sustainable design implementation.

As Los Angeles County grapples with the strains of housing demand, climate change, recovery from wild fires, pandemics, and global tourism — 99NN looks to celebrate local histories and empower communities to shape their built and natural environments, defining the direction of capital investments that benefit community connectedness, strength in adaptation, and community health.


What We Do

Neighborhood Networks


99NN advances three types of neighborhood networks comprising an ecosystem of “resilient community hubs” for gathering and human connection as we adapt to climate events, health events, and even mega events. We center these neighborhood networks at and around parks, river corridors, schools, libraries, and transportation networks—ensuring equitable access to all.

Event-Based Networks activate social connections

Place-Based Networks connect places of home, work, school, shopping, and play.

Map + Story-Based Networks preserve and amplify community culture, history, and purpose.

Community Benefits


99NN aligns with OurCounty sustainability goals by advancing five interconnected community benefits that build neighborhood resilience.

Sustainable Mobility works toward zero-emission transportation corridors and transit hubs that improve air quality and reduce greenhouse gas emissions.

Heat Island Reduction initiatives integrate structured urban cooling strategies with nature-based solutions to combat rising temperatures.

Stormwater Capture through sponge-city infrastructure both replenishes aquifers and mitigates flooding impacts, while improving water quality through filtration.

Greenscaping transforms underutilized spaces into vibrant landscapes that foster pride of place and celebrate local identity.

Community Connections through safe streets, accessible pathways, and wayfinding to promote active living and awareness of current threat levels and response tactics.

By partnering with communities to co-create living streets, cool paths, and story maps, we're not just meeting countywide targets—we're building a connected network of resilient neighborhoods shaped by those who know them best.
