Watershed Planning & Management

Plan the Watershed.
Protect the Community.

Watershed planning isn't just about models and maps. It's about creating a clear path forward for communities facing real stormwater challenges.

We've worked with municipalities and counties for decades, helping them turn drainage problems and flood risks into opportunities for smarter, more resilient infrastructure. Our master plans balance what needs to be built with what needs to be protected, incorporating green infrastructure and nature-based solutions where they fit. Every plan is grounded in solid analysis and tailored to local priorities, with realistic funding strategies that make implementation possible.

We don't stop at planning. We guide communities through the entire process: identifying funding sources, securing grants and loans, and overseeing design and construction of priority projects. Whether you're managing coastal flooding or rapid urban development, we provide strategies that protect people and property, improve water quality, and position your community for long-term success.

Comprehensive watershed and basin studies
Hydrologic and hydraulic (H&H) modeling
Stormwater asset inventory and condition assessment
Criticality analysis and prioritization frameworks
Capital Improvement Plan (CIP) development
Regulatory program review and ordinance updates
Resiliency and vulnerability assessments
Strategic funding planning and grant support
Public outreach and stakeholder engagement

We combine advanced modeling, GIS analysis, and field assessments with collaborative planning to create defensible, actionable watershed plans. Our process includes stakeholder engagement, prioritization frameworks, and integration of resiliency strategies. By aligning technical solutions with funding opportunities and regulatory requirements, we ensure plans are practical, cost-effective, and ready for implementation. The result is a living roadmap that adapts to community needs and future challenges.
