What was Joseph Smith's "City of Zion" plan?
Here's answer to week's question
The Prophet Joseph's "City of Zion" plan, prepared in 1833, contained his ideas about city planning. The plan included "a regular grid pattern with square blocks, wide streets (132 feet), alternating half-acre lots so that houses faced alternate streets on each block, uniform brick or stone construction, homes set back 25 feet from the street, front yard landscaping, gardens in the backyard, farms located outside of town, and the designation of central blocks as a site for temples, schools, and other public buildings."
