Green infrastructure · Puget Sound

Rain is a resource.
Not runoff.

Shoalwater builds green stormwater infrastructure that turns private properties into part of a healthier, more water-resilient watershed.

Every property is an opportunity.

01 / Why it matters

Our cities were built to shed water.
What if they absorbed it?

Rain moving across rooftops, roads, and pavement can carry pollution into our local waterways. Green stormwater infrastructure creates opportunities to capture, slow, filter, and absorb that rain closer to where it falls.

≈
Cleaner waterways

Manage polluted runoff closer to its source.

◌
Water resilience

Capture, slow, infiltrate, and reuse rain where appropriate.

✳
Living neighborhoods

Support plants, habitat, soil, and greener urban spaces.

⌁
Water stewardship

Turn local projects into documented community assets.

02 / The infrastructure

Small interventions.
Connected watershed impact.

The opportunity is already all around us—on rooftops, beside buildings, and across the landscapes of our neighborhoods.

PUGET SOUND / DISTRIBUTED GSI

One property at a time.
One watershed together.

A cistern behind a church. A rain garden beside a school. A restored system at a home. Each serves a property—but together, they can contribute to healthier watersheds across Puget Sound.

THE PHYSICAL INFRASTRUCTURE

Practical interventions designed for existing properties.

Cisterns

Capture and controlled release

Rain gardens

Absorb and filter rainfall

Bioretention

Slow and clean runoff

Permeable surfaces

Allow infiltration

GSI restoration

Restore existing assets

Project types and water benefits depend on site conditions, system design, and maintenance.

03 / What Shoalwater does

From property opportunity to working infrastructure.

Practical project delivery—from the first site conversation to a functioning, documented system.

01 / EVALUATE

Find the opportunity.

Assess roof area, runoff, property constraints, eligibility, and the right green infrastructure approach.

02 / DEVELOP

Plan the project.

Develop a practical site concept, identify relevant programs or funding, and define installation needs.

03 / DELIVER

Build or restore.

Install cisterns and other GSI or rehabilitate existing systems to bring them back into service.

04 / DOCUMENT

Make the work count.

Preserve project records, site information, installation evidence, and modeled benefits where appropriate.

05 / Built in the field

Local experience. Long-term perspective.

Shoalwater's approach is grounded in the practical work of developing, installing, documenting, and restoring green stormwater infrastructure on private property.

Start with a property

Every property is an opportunity.
Every installation is part of something bigger.

Explore green infrastructure for your property—or partner with Shoalwater to develop projects across your community or watershed.

Public rebates and funding depend on site and program eligibility; they are not available for every property.
