This chapter shall apply to all existing employers (both public and private) within the city with the employee threshold number or more employees, defined by resolution of the city council, or those existing employers which reach the employee threshold, and all new development projects that are estimated to generate, either in the project itself or as a result of adding the project to an existing development, the employment of the employee threshold number or more persons, as determined by using the methodology set forth in subsection B of this section.
   A.   For purposes of determining whether an existing development is subject to this chapter, the number of employees will be based on official payroll records and shall be calculated on the annual average number of full time employees.
   B.   For purposes of determining whether a new development project is subject to this chapter, the total number of employees which the project is estimated to generate will be determined by the city of Porterville as follows:

      2.   Employment projections developed by the city engineer or responsible staff using the latest institute of transportation engineer's "Trip Generation Manual"; or
      3.   In the case of a multiuse development, the employment projection shall be calculated on a case by case basis based upon the proportion of development devoted to each type of use.
      4.   The employment projections for land uses not identified above shall be determined pursuant to subsection B1 of this section.
