The owner shall further be required to provide adequate drainage to carry the five year discharge for all water carried through the site and originating on the site. Design of the storm drainage must take into account future development of other commercial sites in the area. Where an owner elects not to construct facilities to accommodate future development, he must provide any necessary easements shown by a drainage study to be needed and must agree to enter into an improvement district at such time as said future develop- ment does occur. 12.24.030 Establishment of Standards and Appeal~ Street cross sections shall be those established by the Master Street Plan for the particular street being improved or that established generally for the functional classification served. Standards referred to in this chapter which are not set forth herein or referred to in other sections of this code have been adopted by the Street and Engineering Committee and are maintained in the City Engineer's Office. The City Engi- neer shall interpret the meaning of all such standards and may revise these standards only through the action of the Street.' and Engineering Committee. Where unusual hardships exist, the City Engineer may waive the requirements of these standards if in his judgment the intent of this chapter; to provide adequate, serviceable, safe and lasting improvements for public use; has been adequately served. Any owner wishing appeal from any part of these standards may appear before the Street and Engineering Committee. After hearing the testimony of the Owner and the City Engineer, the Street and Engineering Committee may vote to either grant or deny the request. The result of this vote shall be reported to the City Council at their next regular meeting.
