Core Responsibilities

Primary Functions

Lead development and update of integrated water resource management plans, urban water management plans (UWMPs), drought contingency plans, and long-term supply and demand studies, ensuring alignment with local, state, and federal regulations and stakeholder objectives.
Conduct hydrologic and hydraulic modeling (e.g., HEC-HMS, HEC-RAS, MODFLOW, SWMM, ResSim) to simulate surface water and groundwater systems, evaluate scenario outcomes, compute water balances, and support infrastructure and operations decisions.
Perform water demand forecasting using demographic, land use, conservation program, and climate projections; prepare scenario analyses to quantify near-term and long-term water needs and evaluate supply alternatives.
Design and manage water resources monitoring programs, including stream gage/groundwater well networks, water quality sampling regimes, data validation procedures, and QA/QC protocols to support planning and regulatory reporting.
Prepare regulatory permitting packages, environmental compliance documents (CEQA/NEPA), technical memoranda, and full-length technical reports that clearly present methodology, assumptions, uncertainties, and recommended actions for decision makers.
Use GIS and spatial analysis to map water infrastructure, service areas, watersheds, groundwater basins, land use patterns, and environmental constraints; produce maps and geodatabases to inform planning and outreach materials.
Evaluate water rights, water availability, and legal/administrative constraints for proposed projects; coordinate with legal counsel, water agencies, and state water boards to interpret entitlements and develop allocation strategies.
Develop, calibrate, and validate hydrologic and groundwater models using observed flow, stage, and groundwater level data; document calibration procedures and performance metrics and conduct sensitivity and uncertainty analyses.
Identify, evaluate, and recommend supply augmentation options (e.g., recycled water, stormwater capture, desalination, conjunctive use, interties, water transfers) including capital and O&M cost estimates, life-cycle analysis, and feasibility studies.
Coordinate multi-stakeholder planning processes including municipalities, irrigation districts, utilities, tribal governments, environmental NGOs, and state agencies; design and facilitate workshops, stakeholder advisory groups, and public meetings to build consensus.
Prepare and manage grant applications, funding proposals, and capital planning packages; develop budgets, schedules, and compliance plans to secure federal, state, and local funding for planning and capital projects.
Integrate climate change projections into planning analyses, stress-test systems under extreme hydrologic scenarios (droughts, floods), and develop adaptive management actions and resilience strategies to ensure reliability under uncertain futures.
Lead project management tasks for complex planning initiatives: prepare scopes of work, monitor deliverables, lead procurement and consultant management, track budgets, and report project status to executive leadership and funding agencies.
Provide technical support for operational decision-making by translating model outputs into operational guidelines for reservoir releases, conjunctive use, demand management, and emergency response.
Conduct benefit-cost and cost-effectiveness analyses for conservation programs, demand response measures, and capital investments; quantify environmental and social co-benefits where applicable.
Prepare and deliver clear, persuasive presentations to councils, boards, advisory committees, and the public; convert technical findings into non-technical summaries, fact sheets, and communication materials.
Support emergency planning and response activities related to water supply disruptions, contamination events, or flood incidents by generating rapid assessments, contingency supply options, and communication materials for stakeholders.
Develop water efficiency and conservation programs, municipal code language, and incentive strategies; measure program effectiveness through performance metrics and adapt programs based on empirical results.
Collaborate with engineers and asset managers to prioritize capital improvements and rehabilitation projects for water infrastructure using risk-based assessment and life-cycle cost analysis.
Lead data integration efforts across SCADA, water quality labs, meter reads, and external datasets; design data workflows to ensure reliable inputs for planning models and dashboards.
Conduct environmental and social impact analyses of proposed water projects, including habitat effects, downstream flows, groundwater-dependent ecosystems, and community impacts; propose mitigation and monitoring plans.
Negotiate interagency agreements and memoranda of understanding (MOUs) for joint projects, water sharing, and operations coordination; draft technical appendices and operational rules to support agreements.
Maintain up-to-date knowledge of regulatory developments, grant programs, technical methods, and best practices in water resource planning and communicate implications to leadership and program teams.
Mentor junior staff and interns; provide technical guidance on modeling practices, report writing, stakeholder engagement, and career development.

Secondary Functions

Support ad-hoc data requests and exploratory analysis for departmental leadership and partner agencies, delivering reproducible datasets and clear methodological notes.
Contribute to the organization's water resources data strategy by recommending tools, data standards, and metadata practices that improve accessibility and model reproducibility.
Collaborate with cross-functional teams (engineering, operations, conservation, finance) to translate planning needs into implementation-ready project scopes and procurement documents.
Participate in internal planning reviews, sprint planning sessions, and program-level coordination meetings to align workplans and deliverables with strategic timelines.
Represent the organization at technical conferences, interagency working groups, and professional associations to share lessons learned and integrate external best practices.
