The Director of Human Resources Management shall be responsible for maintaining an incentive awards program for employees designed to improve the efficiency and economy of County government by recognizing, through appropriate awards, the special talents, creativity, productivity, and resourcefulness of employees. The incentive awards program may include provisions for appointing authorities to recognize extraordinary performance by employees under their jurisdictions pursuant to agency procedures approved by the Chief Administrative Officer. The incentive awards program may also include provisions for the nomination of employees to receive, at the County Executive's discretion, County Executive awards for distinguished or meritorious service. Any incentive award granted pursuant to this Section may be in the form of a gift, grant of annual leave, or nonbase salary payment. Pursuant to procedures promulgated by the Director, an appointing authority may recommend the additional accrual of annual leave days in any leave year for any eligible employee under the appointing authority's jurisdiction where the appointing authority believes the employee's performance justifies such award. Any revenue appropriated in any of the County's current expense budgets to support the incentive awards authorized by this Section shall be maintained in a special, nondepartmental or departmental account and no award authorized shall be granted in excess of the revenue appropriated in any fiscal year to support such program.
