A. It is intended by this chapter that the improvements of primary drainage and major river channels shall be the long range responsibility of the developer and the community as a whole, since the developer and the whole community are benefited materially. The developer of land or improvements within an area containing a primary drainage channel shall design, plan and carry out his developments in a manner that will not interfere with or restrict the natural flow of water or materially change the condition of runoff within the calculated area below the regulatory flood elevation. Increased runoff and changes in primary channels which are created by such developments within primary drainage areas shall be the planning responsibility of the developer and shall be made in accordance with the provisions of this chapter. The improvement of secondary drainage channels shall be the responsibility of the developer, since the primary benefit is to the area served by the secondary channel and not to the community as a whole.
B. Where construction of a storm drainage facility is required along a property line common to two (2) or more owners, the owner hereafter proposing development or use of his property shall be responsible for meeting the required improvements at the time of development, including the dedication of the necessary easements, to accommodate the improvements.
