Section 66006 (b)(1) of the California Government Code requires each local government agency to make public a report on developer fees within 180 days after the close of each fiscal year. Development Impact Fees are a monetary exaction, other than a tax or special assessment, which is charged by a local governmental agency to an applicant in connection with approval of a development project. The purpose of these fees is to defray all or a portion of the cost of public facilities related to the development project.
