RALEIGH — The architecture and design firm Clearscapes has been chosen to design a memorial for Raleigh police officers who died in the line of duty.

The memorial will replace a fountain near the front door of city hall on West Hargett Street downtown. It’s being built by the Raleigh Police Memorial Foundation, which chose Clearscapes for the project and will raise the estimated $500,000 needed to complete it.

The memorial is expected to be finished by May 2014.

Eight Raleigh police officers have been killed in the line of duty since the 1920s, most recently Charles Radford Paul III, who died in 2002 when he lost control of his motorcycle as he was trying to catch up with a speeding car on the Beltline.

Based in Raleigh, Clearscapes has completed more than 100 public and private art installations throughout the country, including memorials to veterans in Garner and to fallen police officers in Clayton.
