Rain Gardens and Stormwater Integration

Exquisite Gardens. Timeless Elegance. Your Sanctuary Shaped by Nature.

Rain Gardens and Stormwater Integration transforms runoff and drainage challenges into planted, functional landscape features. Water is managed with quiet precision to protect the property, improve long-term performance, and deepen habitat value, supported by horticultural rigor and quietly integrated hardscaping that guides flow, resolves edges, and keeps the landscape refined.

Begin the Conversation

Begin with a brief application. If we’re aligned, we start with a short phone conversation and then schedule an on-site consultation as appropriate.

What This Service Is

A rain garden is a designed system that captures, slows, and filters stormwater, then returns it to the landscape through healthy soils and well-adapted plant communities. When done well, it is both an ecological asset and a visual anchor, a place where beauty and function are inseparable.

Stormwater integration can include rain gardens, dry creek channels, subtle swales, infiltration zones, and planted basins, designed to feel natural and intentional within the overall landscape.

What a Rain Garden Provides

Rain gardens do more than solve a problem. They improve how the entire property performs and feels.

Depending on your site, this work can provide:

Runoff control by capturing roof and surface water before it becomes damage
Reduced winter icing risk where runoff previously crossed walks, drives, or approach zones
Less stress on foundations and terrace edges by intercepting concentrated discharge near the home
Reduced pooling and erosion through improved flow paths and infiltration
Reduced sediment movement and hardscape settling by stabilizing flow paths and infiltration
Healthier planting conditions by correcting excess moisture or drought patterns
A designed focal feature that looks intentional, not like a “fix”
Habitat value through moisture-adapted ecological plant communities
Long-term resilience in heavier rain events and changing weather patterns

Who This Is For

Rain Gardens and Stormwater Integration is ideal when you:

Have pooling water, runoff, erosion, or persistently wet areas
Experience winter ice where roof runoff or driveway flow refreezes near the home
Have chronic muddy zones at lawn edges or low points that never fully dry
Want a refined solution that looks like part of the garden, not a utility project
Have downspouts or hard surfaces that concentrate water near the home
Have roof drainage patterns that overwhelm beds, splash zones, or narrow side yards
Want to protect foundations, slopes, plantings, and hardscape from water damage
Want drainage improvements that also increase beauty and habitat value
Are building or renovating and want stormwater designed into the plan from the start
Want water, planting, and quietly integrated hardscaping to work as one system

What We Evaluate

Depending on the site, the work may begin with an assessment of:

Flow paths, grades, and where water collects or concentrates
How the site behaves during real storm events, not only on a clear day
Soil texture and infiltration potential
How infiltration, overflow, and discharge points can be resolved so the system stays resilient over time
Downspout discharge, hard surfaces, and contributing drainage areas
Low points, slopes, and erosion-prone zones
Existing plant performance as evidence of moisture patterns
Opportunities for infiltration, diversion, and planted basins
Where stone, edges, and quietly integrated hardscaping can guide water with clarity

What Stormwater Integration Can Include

This work may include:

Rain garden basin design and sizing appropriate to the site
Ecological planting communities selected for moisture extremes and four-season structure
Stone channels, spillways, splash pads, and subtle grade transitions as needed
Swales, infiltration zones, and planted detention areas integrated into the master plan
Coordination with drainage, excavation, and trade work when the scope requires it
Coordination with licensed professionals for permitting, engineering, or municipal requirements when a project scope calls for it
Establishment and maintenance guidance so performance improves over time

What You Gain

You receive:

A clear strategy for managing water that protects the property
Fewer recurring repairs, fewer surprises, and less seasonal worry around wet zones and drainage
A planted solution designed to look intentional and refined
Improved garden performance through healthier soils and corrected moisture patterns
Strong four-season structure and long-term resilience
A landscape that feels calmer because it is no longer fighting the site
A landscape where water becomes part of the beauty, not an ongoing problem

Where This Fits in The Coan Method™

Rain gardens and stormwater strategy are often identified during consulting and integrated into the master plan, then refined through planting design and installed with care. Subtle, quietly integrated hardscaping is often used to guide flow and protect the garden while keeping the design elegant.

This service most often supports:

Step 1: Consulting (site reading and priorities)
Step 2: Master Plan (property-wide water strategy)
Step 5: Bed Preparation and Step 6: Installation (building and planting the system)
Supported over time through Step 7: Evolution Management

Investment Guidance

Planning ranges vary by scope, site conditions, and materials.

Garden-only projects typically begin around $15,000 to $20,000
Gardens incorporating light hardscape often begin near $35,000
Many residential clients invest $30,000 to $80,000
Larger estate properties are often developed in thoughtful phases beginning at $150,000 and beyond

Scope, sequencing, and overall investment are refined through a paid consultation and master plan prior to construction.

Service Area & Availability

Stephen accepts a limited number of new clients each season to ensure every project receives the highest level of attention, artistry, and horticultural care.

Service area includes Southern and Middle New Jersey and the Philadelphia tri-state region, including Philadelphia, the Main Line, and the Delaware Valley.

A limited number of destination commissions nationwide are accepted each year by invitation.
