Other methods may be used subject to the approval of the Director of Building Inspection. The project developer shall instruct employees to conduct all washing activities in this area. All paved outdoor storage areas shall be designed to minimize pollutant runoff. Bulk materials stored outdoors that may contribute to the pollution of storm water runoff must be covered as deemed appropriate by the City Engineer/Director of Building Inspection.
