Civil Engineer - Stormwater

This position performs professional civil and water resources engineering work associated with the development, calibration, maintenance, evaluation, and review of hydrologic and hydraulic models for the City’s drainage basins and stormwater management system. The position uses modeling, geospatial data, field information, and engineering analysis to support drainage basin studies, capital improvement planning and design, development review, flood-risk evaluation, regulatory compliance, emergency response, asset management, and long-range stormwater planning.

• Develops, updates, calibrates, validates, and maintains hydrologic and hydraulic models of the City’s drainage basins and stormwater system, including pipes, inlets, manholes, culverts, canals, ditches, ponds, pump stations, tide gates, outfalls, and receiving waters.
• Performs rainfall-runoff, open-channel, closed-conduit, storage, pump, tidal-boundary, and flood-inundation analyses using industry-standard modeling software and accepted engineering methods.
• Compiles, evaluates, and quality-checks model input data from GIS, LiDAR, surveys, record drawings, construction plans, field measurements, inspection records, rain and water-level monitoring, tidal data, maintenance records, and documented flood events.
• Calibrates and validates models using observed rainfall, water-level, flow, tidal, and flooding data; documents assumptions, limitations, sensitivity analyses, and model performance.
• Simulates existing and future conditions, including design storms, land-use changes, redevelopment, sea-level rise, tidal conditions, infrastructure failures, and proposed capital improvements.
• Identifies drainage system deficiencies, hydraulic bottlenecks, recurring street and structural flooding risks, and areas requiring additional field investigation, maintenance, rehabilitation, or capital improvement.
• Develops and evaluates conceptual alternatives for stormwater improvements; assists with preliminary sizing, benefit assessment, project scoping, cost estimating, prioritization, and grant justification.
• Reviews drainage studies, hydrology and hydraulic calculations, computer models, technical memoranda, and other engineering documents prepared by consultants and private developers for methodology, accuracy, completeness, consistency, and compliance with applicable City standards and regulations.
• Provides technical modeling support for development review and evaluates potential upstream, downstream, and cumulative impacts of proposed development and redevelopment. Final engineering approvals and documents requiring a professional seal are completed under the responsible charge of a Georgia Professional Engineer.
• Establishes and maintains model-management procedures, including file organization, version control, naming conventions, metadata, quality assurance/quality control, documentation standards, and data retention requirements.
• Coordinates field investigations and monitoring activities needed to improve model accuracy, including surveys, condition assessments, flow and level monitoring, rain-gauge deployment, and post-storm observations.
• Prepares technical reports, maps, flood-depth and duration exhibits, model documentation, dashboards, presentations, and recommendations for City staff, management, elected officials, regulatory agencies, consultants, developers, and the public.
• Develops scopes of work, cost estimates, schedules, and technical requirements for consultant-led basin studies and modeling assignments; reviews consultant progress and deliverables.
• Supports compliance with the City’s MS4 permit and other applicable federal, state, and local stormwater, floodplain, water quality, and resilience requirements; provides technical information for grant applications and regulatory coordination.
• Provides modeling support before, during, and after significant rainfall, tropical weather, tidal, or flooding events; assists with rapid assessments and post-event documentation.
• Coordinates with Stormwater Operations and Maintenance, Stormwater Capital Projects, Water Resources Planning and Engineering, Development Services, Planning, GIS, Emergency Management,…
