Building Resilient,
Active, & Connected Communities

99NN is a 501(c)3 non-profit that supports neighborhoods to be climate-ready and connected through participatory 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.


“Social infrastructure is crucially important, because local, face-to-face interactions – at the school, the playground, and the corner diner – are the building blocks of all public life.”

-Eric Klinenberg (2018), Palaces for the People: How Social Infrastructure Can Help Fight Inequality, Polarization, and the Decline of Civic Life

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 urban cooling strategies with nature-based solutions to combat rising temperatures.

Stormwater Capture through green infrastructure replenishs aquifers while improving water quality for future generations.

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

Community Connections through safe streets and accessible pathways help promote active living—ensuring every resident lives within a half-mile of parks and open space.

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.
