A. General Provisions. The city shall issue a development permit only where adequate provisions for storm water and surface water runoff have been made pursuant to Resolution 517, Storm Drainage Design Standards.

B. Accommodation of Upstream Drainage. Culverts and other drainage facilities shall be large enough to accommodate potential runoff from the entire upstream drainage area, as designated in the city of Talent storm water master plan, whether inside or outside the development. Such facilities shall be subject to review and approval by the public works director or city engineer.

C. Effect on Downstream Drainage. Where it is anticipated by the public works director or designee that the additional runoff resulting from the development will overload an existing drainage facility, the city shall withhold permits of the development until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development in accordance with city standards. Any applicable procedures in state development moratorium statutes shall be followed.

D. Easements. Where a watercourse, drainage way, channel, or stream traverses a development, there shall be provided a storm water easement or drainage right-of-way conforming substantially with the lines of such watercourse and such further width as will be adequate for conveyance and maintenance. Development within designated locally significant wetland and riparian areas shall be in conformance with the requirements in Chapter 18.85 TMC, natural areas, parks and floodplains.
