"[Alrick] Man turned his energies toward developing the outlying Richmond Hill district. Working with his brother [Engineer] Albon [Platt Man, Jr.], he had the land graded (using horse and wagon power in the hilly area) and laid out a road system that curved with the terrain but led as directly as possible into the streets of Richmond Hill, so that the two communities could share 'services and facilities.'  . . .  The area was subdivided. Each house had more land around it than was allotted to each resident in the original Man development of Richmond Hill."
