Contractors working with Uptown Alliance and Seattle Parks and Recreation have begun installing five stones in Counterbalance park, the outcome of a controversial decision to add the rock sculptures. Work begins today (Monday) to install two sculptured basalt columns and three basalt sitting stones, and Seattle Parks expects the project will take two weeks to complete.

Two areas have been fenced off to prepare for the installation.

Some neighbors objected over worries the addition will spoil the minimalist artistic integrity of the park. Seattle Parks agreed with Uptown Alliance, and the city gave the project the green light last month.
