Conduct flood risk assessments, prepare FEMA floodplain mapping (LTRM/MT‑2/MT‑1 submittals as applicable), and write technical reports and risk communications for municipal officials, property owners, and other stakeholders.
Perform groundwater and surface water interaction evaluations, wellhead protection assessments, aquifer testing interpretation, and develop integrated groundwater/surface water conceptual models when required for water supply or remediation projects.
Lead field investigations including flow gauging, stage-discharge measurements, cross-section surveys, sediment sampling, bank stability evaluations, and construction monitoring to collect high-quality data for model development and design.
Prepare and review technical deliverables — reports, feasibility studies, design packages, technical memos, drawings, and specifications — ensuring clarity for clients and compliance with regulatory review standards.
Serve as the primary technical liaison with clients, regulatory agencies, contractors, and multidisciplinary project teams to define project scope, deliverables, schedule, budgets, and success criteria.
Conduct climate change vulnerability assessments for water infrastructure projects that incorporate future precipitation and sea-level rise scenarios, resilience strategies, and adaptation planning.
Provide cost estimating and opinion of probable costs for water resources construction projects, and support procurement processes and construction supervision where needed.
Perform sediment transport and geomorphic assessments to guide channel restoration, bank stabilization, and habitat enhancement projects, balancing engineering performance with ecological outcomes.
Develop and deliver technical presentations, public outreach materials, and stakeholder workshops to facilitate permitting, community buy-in, and implementation of water resource solutions.
Mentor junior staff and supervise field technicians, modeling analysts, and designers; review work products for technical accuracy and professional quality.
Integrate GIS, remote sensing, and LiDAR analysis into project workflows to delineate watersheds, generate terrain products, derive hydro-enforced DEMs, and produce map-ready visualizations for reports and permit submittals.
Apply statistical and data-analytics techniques (R, Python, Excel) to analyze long-term hydrologic time series, flow frequency analysis, trend detection, and automated data processing for model input generation.
Coordinate with multidisciplinary teams (ecologists, planners, civil engineers) to incorporate environmental constraints and stakeholder objectives into site designs that maximize ecological and social co-benefits.
Prepare proposals, scopes of work, technical approaches, and client cost estimates to win new business and expand client relationships in municipal, industrial, and private sector markets.
Ensure project compliance with safety, environmental, and quality management systems, perform risk assessments, and maintain accurate project documentation and field logs.
Review and apply local, state, and federal regulations and standards — stormwater manuals, MS4 permits, state water quality standards, FEMA guidance — to ensure project conformity and expedite regulatory approvals.
Conduct construction observation and as-built verification for stormwater infrastructure and channel restoration projects to confirm that installations meet design intent and regulatory commitments.
Support emergency response planning and post-event assessments (flood damage assessments, emergency stabilization plans) after extreme precipitation or flood events.

Secondary Functions

Support proposal development by contributing technical scopes, staffing plans, schedule estimates, and example approaches for water resources projects.
Maintain and curate hydrologic and hydraulic model libraries, scripts, and templates (Python/R/ModelBuilder) to promote repeatability and accelerate project delivery.
Provide client training sessions on model use, GIS products, stormwater operation and maintenance, and permit compliance obligations.
Contribute to the firm’s thought leadership by authoring white papers, technical blog posts, and conference abstracts on emerging topics (nature-based solutions, urban hydrology, climate adaptation).
Assist with business development activities including networking with municipal clients, utility districts, state agencies, and private developers to grow water resources practice areas.
Participate in internal quality assurance/quality control (QA/QC) reviews and peer technical reviews to ensure high quality deliverables.
Maintain professional licensure and certifications and represent the firm at industry forums, technical committees, and stakeholder meetings.
