Roof water pours down the front of the building. Swirling patterns
of hydrology evoke the sense of rain even when dry.

The term Arroyo refers to a creek that is intermittently dry. In this piece, when it rains, the water is collected from the roof of the Philadelphia fire and police station and piped into the sculpture.  A structure designed in the swirling pattern of water drains rainwater away and into the city’s sewer system.

As the runoff pours through the sculpture, it moves the arced turquoise spinners into a meander-shaped drainage swale to finally join the city sewer system.

The sculpture is kinetic during and just after a rainstorm. Here it is during a storm.

In dry weather, it represents a swirling pattern of water, and the meandering pattern of streams.
