• Strong project management experience, including scope development, budget and schedule management, team coordination, QA/QC, contractor/subconsultant coordination, and delivery of multiple concurrent assignments. (required)
• Experience leading design and construction support for green stormwater infrastructure, LID/BMP retrofits, constructed wetlands, stream or shoreline restoration, resilient public parks/open space, trails, boardwalks, habitat restoration, or comparable nature-based solutions. (required)
• Experience with hydrologic and hydraulic modeling, water quality evaluation, floodplain analysis, drainage system assessment, and stormwater infrastructure planning/design using SWMM-based tools, HEC-RAS, HydroCAD, WinSLAMM, ArcGIS, or similar platforms. (required)
• Working knowledge of stormwater, water quality, wetlands, floodplain, coastal/shoreline, state and federal permitting, NPDES/MS4 compliance, and Clean Water Act-related regulatory frameworks. (required)
• Proven ability to build trusted client relationships, lead stakeholder and public outreach, facilitate meetings, and communicate complex technical concepts clearly to diverse audiences. (required)
