A. In addition to the baseline measurement, employers shall conduct a program evaluation as a means of determining worksite progress toward meeting CTR goals. As part of the program evaluation, the employer shall distribute and collect Commute Trip Reduction Program Employee Questionnaires (surveys) at least once every two years, and strive to achieve at least a 70 percent response rate from employees at the worksite.

B. Employers also have the option of using a sample rather than surveying all of the affected employees or all of the employees at the worksite. Sampling is the process of taking a portion of a population and using statistical methods to ensure that it is representative of the entire population. Validated statistical procedures must be used to ensure that the sample represents the population adequately. All sample survey requests must be approved by the City and the Washington State Department of Transportation. (Ord. 2546 § 2 (part), 2010: Ord. 2420 § 3 (part), 2008).
