§ 5.10. Storm Drainage.

a.

An adequate storm sewer system consisting of inlets, pipes and other underground structures with approved outlets shall be constructed where runoff of storm water and the prevention of erosion cannot be accomplished satisfactorily by surface drainage facilities. Areas subject to flood conditions and/or inadvertent storm water retention (i.e., standing or pooling water), as established by the City, will not be considered for development until adequate drainage has been provided.

b.

The criteria for use in designing storm sewers, culverts, bridges, drainage channels, and drainage facilities shall conform to the City of Waxahachie's drainage criteria in the C & D Manual. In no case shall drainage areas be diverted artificially to adjacent properties or across roadways.

c.

The developer shall ensure that all drainage improvements within public easements or rights-of-way are functioning properly prior to the expiration of the maintenance bond. The developer shall be responsible for removing any significant build-up of sediment and/or trash from drainage improvements, with the exception of backlot and sidelot drainage swales, at the eleventh month of the second year for the required two-year maintenance bond for the applicable facilities. The City shall inspect the improvements to determine any maintenance or correction of deficiencies at the conclusion of this period.
