According to the Christchurch City Libraries street name index
During the 1920s Richard Bedward Owen (1873-1948), a tailor, envisaged the establishment of a boulevard … on both sides of the Avon River from the Carlton Mill bridge to the Estuary … Owen wanted wide lawns between road and river with tall trees planted near the banks.
Clearly a man ahead of his time.
