Does anyone have good examples of codes that require block patterns in suburban multi-family development?
We'd like to require that these developments over a certain size be dived into decent-sized blocks by real internal streets (with tree lawns). Not sure on the specific code language, how big the blocks should be, and what the threshold size for breaking up a development is.
Our downtown/old town block pattern has blocks about 2 - 2 1/2 acres (330' x 330') or a bit more. However, we're looking at more suburban developments, which will no doubt be permeable to pedestrians and even drivers as they will contain a mix of buildings, parking and open spaces.
Recognizing this, I'm not sure how large the max block size should be. One example I've seen requires blocks of no more than 4 acres; which translates into a little over 400' x 400'. Hope to find other examples to back up what we are trying to do, as this is new ground.
