A. When property that contributes drainage to the storm drain system or combined sewer system is improved or developed, all stormwater and surface runoff drainage impacts resulting from the improvement or development shall be fully mitigated to ensure that the improvement or development does not affect the function of the storm drain system or combined sewer system, and that there is no increase in flooding or in water surface elevation that adversely affects individuals, streets, structures, infrastructure, or property.
B. The director shall develop and maintain a design and procedures manual setting forth standards, criteria, and requirements for the planning, design, and construction of water, sanitary sewer, storm drainage, and water quality facilities, to assure that these facilities are properly planned, designed, and constructed, and to comply with the mitigation requirement set forth in subsection A of this section. The director shall have the authority to change, update, or revise this manual.
C. The improvement or development of property that receives city water service, contributes sewage to the separate sewer system or combined sewer system, or contributes drainage to the storm drain system or combined sewer system, shall comply with applicable provisions of the design and procedures manual as a condition of receiving any permit or approval required for the improvement or development.
