Prior to any site grading or excavation, as defined in section 22-531 and not excepted in section 22-533, a subdivider proposing significant development or redevelopment shall submit a plan for the control of the quality of stormwater drainage to the general manager. Such plan shall include all facilities and control measures necessary to ensure continuing compliance with the rules and regulations promulgated under section 138-438. Such subdivider shall be responsible for design, construction, and effective operation of the facilities and measures set forth in the plan. Approval by the city of any plans shall not create a liability on the part of or cause of action against the city or any officer or employee thereof regarding the plan or its operation, nor does this article purport to reduce or obviate the need for the subdivider to obtain any other local, state, or federal licenses or permits. Specific plan requirements, processing procedures, and approval criteria shall be set forth in the rules and regulations promulgated under section 138-438. Approval of the plan required under this section for the control of the quality of stormwater drainage with regard to proposed significant development or redevelopment is required to obtain the permit described in section 138-442.
