Engineering Design Criteria & Standard Specifications and Construction Drawing


These documents, Engineering Design Criteria and Standard Specifications and Construction Drawings, were adopted by the City of Norman City Council on September 24, 1996, and adopted revisions on April 28, 1998; March 28, 2000; May 8, 2001; July 24, 2001; February 26, 2002; September 9, 2003; January 11, 2005; June 13, 2006; and July 11, 2006.


The Engineering Design Criteria, together with the City of Norman's Standard Specification and Construction Drawings regulate both public improvements and private work which will either be dedicated to or accepted by the City. In addition, all work within the public right-of-way is governed by these regulations. They are intended to provide for coordinated development with adequate facilities to serve and protect the users.


These documents are meant to provide minimum criteria and to apply rigidly to new developments which are not constrained by already existing improvements. Designers are encouraged to exceed these criteria whenever possible to provide better engineered facilities. Infill development in an urban area is often constrained when matching existing improvements. To the extent deemed possible by the City Engineer, infill developments shall be completed in accordance with this Engineering Design Criteria document. The City Engineer however, may allow modifications of these requirements when necessary to allow private and public construction which is compatible with surrounding in-place improvements.


These design criteria, standards specifications and construction standards shall also be used in conjunction with the City's zoning regulations and subdivision ordinances for site development work on private property.
