In 2005 the Borough published an Open Space Plan that has lots of interesting information and maps. Once interesting tidbit we noticed was that based on the potential development the projected number of residents of Conshohocken Borough would grow by 3,832 people (pg. 61).
The Grande, Riverwalk and Londonbury have already eaten into that number by about 1,500 people, so all the more recent proposed residential development will move the needle by another 1,500.
If you are interested in the Borough, you will find the Open Space Plan an interesting read, even if you just skim through it.
