Is there a height limit to block walls used as fencing ?
I currently have a block wall that is approx. 19' tall. It has a retaining wall that is 15' out and 3' high that slopes up to approx' height of 6' against the main wall leaving 13' of exsposed wall above the retainer. There are houses that share the other side of the block wall however the lots are elevatedto the point that the block wall from there perspective is 6' tall. My question is this: do we need more of a retaining wall ?(hieght & depth) to support such a wall and are flying butresses required where side yard walls connect to main wall to help support it ? My city ordinance calls for block walls no higher than 10' without supporting retianers of some kind. Any information would be greatly appreciated. Thanks, j.
