Birch Street is Easily the Most difficult Road on LID 54
Low Volume Road
Not a major benefit for the City as a whole
Roadway is in poor condition
Continual problems with flooding and runoff
There really is no Great Solution
Making the Best of a Bad situation

Questionable Neighborhood Support
To make this much better something has to give.
High expense to benefit ratio
