Lead water quality assessments and best management practice selection for pollutant removal (TSS, nutrients, bacteria), perform pollutant loading calculations, and develop stormwater pollution prevention plans (SWPPP) and NPDES permit support documentation.
Conduct field investigations and site reconnaissance including stream cross-section surveys, bathymetry, topographic/LESA data review, sediment and debris assessments, groundwater observation, and collection of hydrologic and meteorological data to support modeling and design.

Manage permitting and regulatory compliance efforts for Clean Water Act Section 401/404, state wetland and water quality permits, coastal zone management, and local erosion & sediment control ordinances; prepare permit applications and coordinate agency reviews and mitigation plans.
Lead multi‑disciplinary project teams and coordinate inputs from environmental scientists, geotechnical engineers, landscape architects, and planners to integrate habitat restoration, stream restoration, and green infrastructure into engineering designs.
Provide client-facing project management including scope definition, scheduling, budgeting, progress reporting, and quality assurance/quality control (QA/QC) of technical deliverables; proactively manage project risks and change orders.
Perform legacy data analysis, assemble and QA/QC hydrologic and long-term streamflow records, process precipitation and evapotranspiration datasets, and develop synthetic storm or hydrograph inputs for model forcing.
Perform sediment transport, scour analysis, and morphological change assessments for bridges, channels, and coastal structures using appropriate analytical or numerical methods; recommend scour protection and resiliency measures.
Evaluate pump station hydraulics, pump selection criteria, surge/transient analysis, and power/backup requirements; collaborate with mechanical/electrical disciplines for integrated design.
Provide construction administration and observation services, review contractor submittals, respond to RFIs, perform site inspections, and verify as-built elevations and system performance against design intent and permit conditions.
Prepare grant applications, feasibility studies, and cost-benefit analyses to support funding opportunities for flood mitigation, watershed restoration, or stormwater infrastructure improvements.
Integrate GIS analyses for watershed delineation, terrain processing (DEM/TIN), land-use change impacts, and spatial visualization of model outputs for stakeholder communication and decision-making.
Develop and implement monitoring plans—stream gauges, ADCP surveys, water quality sampling protocols—and process monitoring data to assess post-construction performance and adaptive management measures.
Support emergency response and flood event assessment, including rapid modeling of flood extents, inundation mapping for public safety, and post-event damage assessments and reporting.
Maintain technical documentation, standard operating procedures, templates, and model libraries to ensure reproducibility and efficiency across projects; mentor junior staff on modeling best practices and report writing.
Stay current with advances in hydrologic/hydraulic modeling, climate projection integration, green infrastructure performance metrics, and federal/state regulatory updates; translate emerging guidance into practice on active projects.
Perform value engineering and constructability reviews to optimize project cost, reduce lifecycle maintenance needs, and recommend resilient designs that consider future sea-level rise and extreme precipitation trends.
Coordinate public outreach, present technical findings to non-technical audiences, and participate in stakeholder meetings, municipal council briefings, and interagency workshops to build consensus and support for projects.

Secondary Functions

Support proposal development and business development activities by providing technical scopes, resource estimates, and credibility statements for water resources projects.
Assist in the development and maintenance of hydrology/hydraulics model databases, templates, and automated workflows (Python, MATLAB, or R scripts) to improve repeatability and efficiency.
Contribute to internal training programs and brown-bag technical sessions to elevate team competency in H&H modeling, permitting strategies, and design standards.
Participate in peer reviews of technical deliverables and mentor junior engineers on quality control, report structure, and professional development.
Support cross-discipline coordination for utility relocation, roadway drainage interfacing, and land-development stormwater management during planning and permitting phases.
Help prepare visualizations, animations, and GIS story maps that translate complex model outputs into accessible formats for clients, regulators, and the public.
Monitor and document project KPI metrics such as schedule adherence, budget performance, and QA/QC outcomes to support continuous improvement.
Support R&D or pilot projects testing green/low-impact development practices, real-time control systems for stormwater, or novel modeling approaches for urban flooding.
