 In 1989 the Tulare Joint Union High School District retained the firm of Earth Metrics to forecast district growth and analyze the facility needs of the system in future years.In the 1980s the California Legislature changed the rules governing school facilities financing by authorizing school districts to directly levy School Impact Fees (sometimes called "Developer Fees"), and by deeming the School Facilities Act the exclusive means by which cities and counties can address the overcrowding of schools.Thus at that time the district forecast the future enrollment and established appropriate development fees to finance forecast facilities needs to expand Tulare Union High School and other district facilities.
