Project Engineer – Recharge Master Plan & Basin Planning (3-8 Years Experience)

Position Summary

We are seeking a motivated Water Resources Engineer with 3-8 years of experience to support the development and implementation of regional groundwater recharge planning efforts and related groundwater management initiatives. The engineer will work closely with senior technical staff to evaluate recharge opportunities, develop planning studies, develop conceptual engineering designs, coordinate with agencies, analyze hydrologic and hydraulic data, and prepare technical reports that support long-term groundwater sustainability, stormwater capture, and water supply reliability.

This position is ideal for an engineer who enjoys combining technical analysis, planning, field investigations, and collaboration with public agencies.

Essential Responsibilities

Recharge Master Planning

• Support preparation of Recharge Master Plans and basin-wide planning studies.
• Evaluate existing recharge facilities and identify opportunities to increase stormwater, recycled water, and supplemental water recharge.
• Assist with development of conceptual designs for recharge projects, including spreading basins, conveyance improvements, recharge wells, and regional stormwater facilities.
• Develop planning-level cost estimates, implementation schedules, and project prioritization matrices.
• Assist with preparation of grant applications and supporting technical documentation.

Hydrology & Hydraulic Analysis

• Analyze precipitation, runoff, groundwater recharge, and streamflow datasets.
• Estimate hydraulic capacity and design flows of stormwater control and conveyance infrastructure.
• Assist with watershed modeling using data processing and visualization tools, including scripting languages (e.g., Python).
• Evaluate stormwater capture potential under existing and future land use conditions.

Groundwater & Basin Management

• Support groundwater basin evaluations, recharge accounting, and storage assessments.
• Assist with interpretation of groundwater level trends and monitoring data.
• Evaluate recharge impacts on groundwater sustainability, safe yield, hydraulic control, and basin management objectives.
• Support preparation of annual basin reports and recharge accounting documentation.

Stormwater & MS4 Planning

• Evaluate municipal stormwater (MS4) projects for recharge benefits.
• Review Water Quality Management Plans (WQMPs) and Low Impact Development (LID) strategies.
• Support development of regional stormwater recharge strategies and implementation plans.

Technical Reporting

• Prepare technical memoranda, planning reports, figures, GIS maps, and presentation materials.
• Develop tables, charts, and graphics summarizing recharge capacity, project costs, water budgets, and implementation priorities.
• Assist with preparation of Board presentations and stakeholder workshops.

Field Work

• Visit recharge facilities, spreading grounds, channels, and stormwater infrastructure.
• Observe infiltration
