The Development Fee Estimate workbook can be used to estimate a development project’s impact fees during the planning process. Enter the project information in the gray cells in the Data Sheet. The fees will be automatically calculated and summarized on the Summary Sheet. The assumptions and calculations can be reviewed in tabs for each department (e.g., Parks, Public Works, Police, Fire, etc.). Additional fees may apply, such as housing in-lieu fees and/or tree mitigation in-lieu fees. Fees will be verified upon submittal of a building permit. For any questions, please contact the Community Development Department staff by calling (707) 838-1021.
