Artist Peregrine Church has created Rainworks, a project that turns Seattle's over abundance of rain into an opportunity to enliven street life. Using stencils and a non-toxic, biodegradable "superhydrophobic coating" made of nano-particles called Always Dry, Church has created a fun, do-it-yourself template, demonstrating how to use concrete pavement as a canvas for artworks, illustrations, and messages — but only when wet.

Church has created about 25-30 works of "rain-activated art," featuring messages like "Stay Dry Out There," a lily pond filled with frogs, a fun hopscotch game, and other natural patterns.

According to Church, the coating of nano-particles only last about 4 months to a year, given wear and tear. "A rainwork is the most vivid during its first couple of weeks, then slowly becomes more subtle."

Rainworks is actually legal, too. Church checked with the Seattle department of transportation, which gave the OK, because the works are "temporary, don't harm the property, and don't advertise anything." Also, the concrete retains the same texture once it has been sprayed. The material leaves "zero residues and is 100 percent invisible, odorless, and doesn't alter the texture of the substrate."

In this brief video, Church says: "It's going to rain no matter what. Let's do something cool with it."

Another D-I-Y way to improve street life and, really, a whole city's approach to accessibility, is Walk [Your City]. This non-profit started by Matt Tomasulo, a landscape architect, enables communities to order and install their own signs explaining how far it is to walk to different locations. Cities like Santa Fe, New Mexico; West Hope, West Virginia; Atlantic Beach, North Carolina, have all used Tomasulo's process and signs to create more walkable places. See Walk [Raleigh], which won an ASLA student award in 2012 — and really started it all.
