Here is a mid-block retail frontage in T4. The SmartCode calls for retail only at corners, but where local patterns support it, the code could call for one midblock business per block, or could support a T4-Open zone for an entire block, which is T4 in form and Open in general function (use). Spring Street with its scattered retail has a T4-Open character. Search on Spring Street for other images. This, however, is Barney Street.
