Green Infrastructure and Rain Garden Design
Design of rain gardens, bioswales, permeable pavement and infiltration systems to meet stormwater rules or reduce runoff.
What the work involves
Green infrastructure manages runoff close to where it falls using infiltration and vegetation. Engineers check soil infiltration rates, size practices, design overflows and coordinate planting with landscape architects. Many municipal stormwater rules now prefer or require these practices, and some offer stormwater fee credits.
Local conditions we plan for
- Coastal flooding and storm surge in New York City and Long Island
- Frost depth and heavy snow upstate
- Aging infrastructure, bridges and older buildings
- Lake effect snow loads in western New York
Building code: 2024 IBC/IRC adopted at the state level (ICC adoption chart, April 2026).
When you need it
- Stormwater rules require runoff reduction
- Stormwater utility fee credit program
- Limited space for a detention pond
- Homeowner wants to reduce yard runoff
Frequently asked questions
How much does green Infrastructure and Rain Garden Design cost?
Across the US, green Infrastructure and Rain Garden Design usually costs $1,500 to $25,000. Estimate. Residential rain gardens are at the low end; commercial permeable pavement and bioretention at the high end.
How long does green Infrastructure and Rain Garden Design take?
Plan on 2 to 8 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for green Infrastructure and Rain Garden Design?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in New York?
Engineers practicing in New York are licensed by the New York State Board for Engineering, Land Surveying and Geology (NYSED Office of the Professions). You can confirm a license number and its status in the board's public license search before you sign a contract.
Which building code applies in New York?
2024 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
What site problems do engineers see most in New York?
Common issues include coastal flooding and storm surge in New York City and Long Island, frost depth and heavy snow upstate, aging infrastructure, bridges and older buildings and lake effect snow loads in western New York.
