Stratford Place

Stratford Place is a 20 lot housing development constructed in 2006 in Sultan, WA. It is the first such development in the Northwest to utilize pervious concrete for streets, sidewalks, and driveways.

This project won the Excellence in Concrete Award in 2006 from the Washington Aggregates and Concrete Association (WACA).

It has endured snow storms, freezing, and a several 50 year rain storm events and flooding.
