Definition

Under direction, the incumbent is responsible for review, analysis, and reporting on issues related to water policy including groundwater and surface water quality and quantity, water supply analysis, flooding, including the operation and monitoring of the County's ALERT flood warning system; and perform other duties as required.

Distinguishing Characteristics

This single position class is distinguished from the Resource Planner series in that this class provides hydrological expertise for the County while the Resource Planner series is responsible for a variety of environmental and resource planning studies.

Typical Tasks

Analyze complex hydrological, geohydrological, water resource and water quality data; implement Board of Supervisor's policy; may staff various commissions and committees including preparation of agendas, minutes, staff reports and chairing meetings; make presentations to boards, commissions, committees and community groups; operation of the County's ALERT flood warning system including the purchase and installation of precipitation and stream gauging equipment, providing forecasts of flood levels, providing technical expertise to the Emergency Operations Center, and coordinating information with other jurisdictions and agencies; prepare and review technical reports and other water related materials to coordinate groundwater and water supply planning and water resource management with major water purveyors; technical plan review for the Environmental Review Committee or other County agencies and departments on projects affecting surface and groundwater; provide water use analysis and evaluation of impacts to water quantity, water quality and/or natural groundwater systems from mining operations, seawater intrusion and other water related activities; respond to requests for water related public information from consultants, other County staff or interested persons; conduct field investigations or special studies to collect water resource data; research complex surface and groundwater resource issues or to evaluate natural recharge systems as they relate to the interaction between surface water and groundwater systems.
