Stormwater Engineering Services Designed for Reliable Performance
Managing Runoff With Practical, Code-Compliant Systems Built for Long-Term Reliability

Stormwater Systems That Work in the Field
Windsor provides stormwater engineering services for municipalities, infrastructure improvements, and land development projects. We design detention, conveyance, and treatment systems that manage runoff effectively while meeting local and state regulatory requirements.
Stormwater projects often involve tight sights, complex permitting, and coordination across multiple disciplines. Our team works early to define constraints, confirm assumptions, and reduce risk before construction begins.
How We Work
Define Site and Regulatory Constraints:
We begin by reviewing site limitation, hydrologic data and jurisdictional requirements to define performance targets.
Coordinate Across Disciplines:
Stormwater systems intersect with civil grading, utilities, and structural components. We coordinate early to avoid conflicts.
Confirm Constructability:
We validate phasing, access, and installation sequencing to reduce change orders and field modifications.
Support Through Construction:
We remain available to clarify design intent and address field conditions that may impact system performance.
Our Capabilities
Stormwater System Planning & Watershed Analysis
We support stormwater planning and watershed analysis to understand system behavior and guide long-term, buildable solutions.
Stormwater Conveyance & Drainage System Design
We design conveyance and drainage systems that manage flow effectively while integrating with surrounding infrastructure.
Low Impact Development (LID) & Environmentally Sensitive Infrastructure Solutions
We design LID and environmentally sensitive infrastructure systems that manage stormwater naturally while meeting regulatory and site requirements.
Stormwater Detention, Retention, & Water Quality Facilities
We design detention, retention, and treatment facilities that control flow, improve water quality, and support long-term system performance.
Flood Control & Infrastructure Resilience Planning
We support flood control and resilience planning to reduce risk and improve system performance under changing conditions.
Hydrologic & Hydraulic Modeling
We perform hydrologic and hydraulic modeling to inform design decisions and predict system performance across a range of conditions.
Stormwater Permitting & Regulatory Compliance
We coordinate permitting and compliance to support clear approvals and reduce project risk.
Construction Administration & Implementation Support
We support construction with coordination and oversight to ensure stormwater systems are implemented as designed.
