There are many advantages to using permeable pavers over Silva Cell installations. The two biggest are maximizing stormwater volume, rate, and quality benefits, and minimizing installation and maintenance labor requirements. In today’s post, I’ll be discussing these two stormwater benefits (as well as a few extras!) in more detail.

I have been wanting to write about the history of street trees. When I sat down to begin my research, I started in the usual place: Google.

The aggregate is strong enough… More
There are many physical markers of the long process of growing up: the improbably tiny clothes we once fit in to, the toys and gadgets that occupy us, the notches on the door jamb that record our height year over year. The metaphors for these changes, that signify the growth, transition and development of human… More

A couple of weeks ago, Montgomery County, MD held a public hearing on two bills intended to protect trees that seem to be causing divisions in the community. It’s interesting how an issue as seemingly harmless as tree preservation can cause a political kerfuffle. I shouldn’t be surprised, though. The devil is, as they say,… More
