5-7(F)(1)(a) Retaining walls shall have a maximum height as specified in Section 14-16-5-7(D) (Maximum Wall Height) unless a higher wall is approved by the City Engineer as necessary on a particular lot.
5-7(F)(2)(a) A terrace at least 4 feet wide, with a maximum slope of 1:3 (rise:run), shall be provided between each tier to create pockets for landscaping. Reduced terrace depths may be administratively approved by the City Engineer where site constraints limit the amount of space available to accommodate the minimum required width.
Retaining walls must be set back so that the underground footing does not encroach on any abutting public right-of-way.
