D. Findings. In order to approve modifications to subdivision standards, the advisory agency must make at least one of the following findings:

  1. That the modification of design criteria and improvement standards is necessary for the subdivision and its design and improvements to be found consistent with the general plan; or

  2. That the subdivision is subject to a specific plan which requires or authorizes the construction and installation of streets, sanitary sewers, storm drain management systems and/or other improvements alternative to those design criteria set forth in Title 18R of this code, and that modification is necessary in order that improvements to be constructed and installed or as a condition of approval will conform to the alternative design criteria and improvement standards as set forth in such specific plan; or

  3. That the subdivision will result in one or more significant environmental effects identified in an initial study or an environmental impact report prepared in accordance with the California Environmental Quality Act, and the city's Environmental Review Guidelines, established in Chapter 1.40 of this code, and that modification of the design criteria and improvement standards, contained in Title 18R of this code, is necessary to mitigate such significant environmental effect or effects; or

n an initial study or an environmental impact report prepared in accordance with the California Environmental Quality Act, and the city's Environmental Review Guidelines, established in Chapter 1.40 of this code, and that modification of the design criteria and improvement standards, contained in Title 18R of this code, is necessary to mitigate such significant environmental effect or effects; or

  1. That any part of the subdivision is located in an area which contains existing streets, sanitary sewers, stormwater management systems or other improvements which do not conform to the design criteria and improvement standards established in Title 18R of this code, and that modification of such design criteria and improvement standards is necessary in order to make the streets, sanitary sewers, storm water management systems and other improvements to be constructed and installed or as a condition of approval of such subdivision compatible with such existing and nonconforming improvements; or

  2. That the subdivision is of such a size or shape, or is affected by such topographic or soil conditions that render it impossible, impractical or undesirable, to conform to the design criteria and improvement standards, established in Title 18R of this code, and that modification is necessary by reason of such subdivision characteristics or conditions;

or
