(A) Storm drainage facilities required. Underground storm drainage facilities shall be provided where the run-off storm water and the prevention of erosion can be accomplished satisfactorily by surface drainage. All drainage facilities shall be constructed in accordance with the Comprehensive Plan and city requirements.
(B) Subdivider to provide storm drainage facilities. The subdivider shall bear all costs of storm sewer and drainage facilities required to serve subdivided property. The city will not accept any storm sewer or drainage facility until inspected and approved by the Public Works Director for compliance with the regulations. No such facility will be approved to serve illegally subdivided property. If the city requires large storm sewer or drainage facilities than are necessary to serve the subdivision in order to provide for future development, the city will consider participation in such oversize contract for the cost of such to be recovered from subdividers of property that will connect to such lines.
(C) Adequate facilities required. An adequate storm sewer system consisting of inlets, pipes, and other underground structures with approved outlets and channels shall be constructed where runoff or storm water and the prevention of erosion cannot be accommodated satisfactorily by surface drainage facilities. Areas subject to flood conditions will not be considered for development until adequate drainage has been provided.
(D) Construction to conform to design standards. The criteria for use in designing storm sewers, culverts, bridges, drainage channels, and any other drainage facilities shall conform to the latest Storm Drainage Criteria and Design Manual of the City of Fort Worth. A Corps of Engineers permit shall be obtained by the subdivider for proposed earthen channels and altering existing channels or creeks. Earthen channel side slopes shall be four to one or flatter.
(E) Specifications for materials and workmanship. The specifications for materials and workmanship shall conform to the Standard Specifications for Public Works Construction, published by the North Central Texas Council of Governments.
