So now, after a few months you’ve fortified the inside, made it safe, redundant and ensured the systems are set for survival for a long time, and you’ve expanded your group, you need to expand the base itself.

First Priority is fencing and containing the external area, with the Costco itself as the epicentre / Base Hub.

This will ensure if any attacks occur, you at least have a fallback base, which is still fortified.

Primary Outer Fence

A long-term settlement could begin with a large perimeter fence surrounding:

parking lots
loading bays
fuel/storage zones
greenhouse areas

Possible materials:

chain-link fencing
welded steel mesh
reinforced construction fencing
salvaged industrial barriers

If you have barbed wire, add that on top to reduce unwanted guests…
Or, make it electric 😉

Double-Layer Perimeter

Some settlements use:

an outer warning boundary
an inner protected perimeter

The space between can function as:

maintenance corridor
inspection route
lighting corridor

⸻

Vehicle Barrier Sections 🚚

Large vehicles placed along portions of the perimeter can act as:

wind barriers
visual barriers
reinforcement for fencing sections
Or even areas for heightened visibility

Examples:

delivery trucks beds
shipping containers
trailers

⸻

Fence Support Structures

Additional supports:

concrete barriers
steel posts
pallet walls
sand-filled containers

Access Points 🚪

A perimeter usually includes:

one main entrance / exit gate
emergency exits

Often marked with:

floodlights
warning paint
signage

Utility Integration ⚡

Perimeter areas may also contain:

motion lighting
cameras
solar lighting systems
maintenance power lines
communications wiring

If you produce enough power, well you have your own mini military base.

Long-Term Expansion 🌱

Over time, the perimeter may expand to include:

farming plots
solar fields
workshops
water storage
vehicle yards

This timeline might be unrealistic for certain groups, or if supplies surrounding are limited, or certain situations arise,
but if you have 50+ people qualified and trained in specific fields, this could be achieved.

This could be a good starter idea for what the Costco could look like in the same time line.

It’s up to you and your group on what you keep inside the facility after moving outdoors.

Scale Food Production

Indoor hydroponics becomes backup food.

Expand to:

Large crop fields
Livestock zones
Aquaponics ponds
Orchards
Seed banks

Goal: Produce surplus food, not just survival rations.

Create Real Power Infrastructure

Move beyond generators.

Add:

Solar farms
Wind turbines
Water turbines if nearby rivers exist
Large battery banks
Grid distribution systems

Goal: Stable 24/7 electricity.

Build Regional Communication Networks

Develop:

Radio towers
Signal repeaters
Long-range communication posts
Mapping systems
Recon drone systems

Goal: Control information and maintain awareness.

Establish Trade Routes

Once stable, your settlement becomes valuable.

Trade:

Food
Water
Medical supplies
Power
Tools
Security services

Goal: Build alliances instead of constant conflict.


Take over another Costco or big box store, and expand.

Create Layered Defense Systems

Security becomes military-level organization.

Add:

Outer patrol zones
Observation towers
Vehicle barriers
Quick response teams
Early warning systems

Goal: Defend territory, not just one building.

Expand Beyond Costco

Eventually the warehouse becomes the “capital.”

Expansion includes:

Farming villages
Industrial zones
Fuel depots
Guard outposts
Water facilities
Mining/scrap operations

Goal: Create a networked civilization.

This is the beginning of having a mini city functioning, with water, food, shelter, workshops, electricity.

This is critical for anyone facing apocalypse scenarios and it’s critical you get these skills before hand, or have members of your group that know these areas.

This is what we have the channels for.
