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
- Frost depth and freeze thaw damage to roads
- Great Lakes shoreline erosion and fluctuating lake levels
- Heavy lake effect snow loads
- Aging water and stormwater infrastructure
Building code: 2021 IBC and 2015 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 Michigan?
Engineers practicing in Michigan are licensed by the Michigan State Board of Professional Engineers. 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 Michigan?
2021 IBC and 2015 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 Michigan?
Common issues include frost depth and freeze thaw damage to roads, great Lakes shoreline erosion and fluctuating lake levels, heavy lake effect snow loads and aging water and stormwater infrastructure.
