WATER IN THE LANDSCAPE

Catch the rain.
Make room for reuse.

Roof water stored for later. Rainfall welcomed into the ground where conditions allow. Suitable household graywater directed to landscape irrigation. Each has a different role in a whole-site water plan, with soil conditions guiding the approach.

FIRE, WATER & THE LANDSCAPE

Resilience starts
at the home.

Plant hydration matters alongside home hardening, fuel maintenance and thoughtful spacing. Explore fire ecology and lessons from Greg Rubin’s work with California native landscapes.

Explore layered fire resilience
Conceptual sepia engraving of a home surrounded by a broad bare gravel and stone apron, with separated planting farther away.

AI-generated conceptual illustration. An imagined property, not a completed project or site-specific design. No landscape is fireproof.

  • Harden the home
  • Keep immediate surroundings noncombustible
  • Manage vegetation spacing and dead fuel
  • Maintain plant health and ongoing care

Prioritize the first five feet around structures and decks; confirm current local fire requirements. The illustration does not show every home-hardening detail or establish compliance.

A WHOLE-PROPERTY PERSPECTIVE

A good place
is a living
relationship.

Abundance, comfort, water and care belong in the same conversation.

The Engineering Paradise philosophy adds a wider set of questions: how can land support life, health, security, comfort, useful work and belonging? The answers begin with the place and the people who will care for it.

PARADISES & PRACTICAL HISTORY

Ideas of refuge.
Evidence of ingenuity.

Let cultural reflection enrich the questions, then look closely at how real places have worked.
