Three Layers of Neighborhood Infrastructure

Layer 1: Relational Layer (Foundation)

Who knows whom? Where does trust live? This is the bedrock. Most builders want to skip to Layer 2, but the strongest infrastructure builds this layer first.

Layer 2: Information Layer

How do people learn what's happening? Calendars, channels, newsletters, directories — the connective tissue of neighborhood awareness.

Layer 3: Action Layer

How do people help each other? Mutual aid, shared resources, collective projects, tool libraries, cooperative care.

The Outer Sunset Ecosystem (Reference Implementation)

Neighborhood Scale (Public)

• Outer Sunset Today — Community calendar & daily digest (outersunset.today)
• Community Guide — Directory of local groups (outersunset.us)
• Field Guide — Walking exploration app with past/present/future (outersunset.place)

Block Scale (Semi-Public)

• Cozy Corner — 48th Ave block hub for events, ideas, links (cozycorner.place)
• Community Supplies — Tool, gear & book lending library (communitysupplies.org)
• Block Party Planner — Event coordination
• Flyer Map Maker — Design tool for outreach

Private Channels (Invite-Only)

• Mutual Aid Pod (25 members)
• Block Neighbors (35 members)
• Affinity groups (parents, etc.)

These three scales — neighborhood, block, private — form a pattern that can be adapted to any place.
