(A) The interpretation of the requirements set forth in this chapter shall be made by the City's Engineer or designate, unless specified otherwise by the Council. The developer shall be responsible for the conveyance of all storm drainage flowing through or abutting the subject property, including drainage directed to the property by prior development as well as that naturally flowing by reason of topography.
(B) Where new drainage improvements are required along the boundary of a site, the owner proposing development shall be responsible for designing and constructing all the required improvements at or before the time of development, including the dedication of all necessary rights-of-way or easements necessary to accommodate the improvements. Where the developer proposes to develop only a portion of the property, only the drainage improvements for the portion being developed shall be required to be installed, except as drainage improvements outside the portion being developed are deemed necessary by the city for proper drainage of the portion being developed.
