This is advanced supervisory and technical landscape and grounds maintenance work at various county properties and installations.

Employees in this class supervise a large staff of subordinates, frequently through subordinate supervisors, engaged in landscaping and grounds maintenance activities at metropolitan parks, community parks, roadway median strips and other locations. Some employees may be assigned responsibilities for landscape construction activities or for supervision of an extensive county plant and tree nursery operation. Incumbents generally supervise landscape and grounds maintenance of a combination of large metropolitan parks, community parks, special activity parks and roads and trails which are equal to an extensive area of acreage. Employees exercise independent judgment in scheduling crews and equipment and in determining work methods and procedures. Supervision is exercised generally through subordinate supervisors, over a staff of equipment operators, attendants, technicians and laborers, and may include volunteer and contract workers, and prison inmates, frequently dispersed to several separate geographical locations. Supervision is received from a technical or administrative superior who reviews work for completion of assigned responsibilities.
