The Design Manual and Standard Plans were prepared to provide guidance to engineers preparing improvement plans for the City of Irvine. Engineers are assumed to use good engineering judgment and not limit their designs to minimums or maximums stated in the manual.
Existing conditions of terrain, drainage, etc., may cause specific problems and the engineer is advised to discuss these problems and receive approval for deviations from the City of Irvine prior to submittal of the tentative map and/or improvement plans.
