Monroe Addition to Monrovia Tract
William N. Monroe bought a large amount of property in the area that was to become Monrovia both on his own and with others in partnership. He chose the property close to the foothills to purchase for himself for several reasons. Obviously, the main reason was that at the time, it was a great investment. Elias J. Baldwin needed money and was willing to sell the property for $125 an acre. Because the land was close to the foothills, it offered protection for citrus trees against frost.
Monroe's property was located in the large square marked B , and his brother, C.O. Monroe's property was located in Block F. Though the property was landscaped, it was not set up for citrus production. Monroe was far too busy with his various real estate businesses, civic obligations, and city government participation to involve himself with citrus ranching, though he did have citrus on his property. His brother, C.O. Monroe did plant his property in citrus as did other large land holders in the Monroe Addition like the Spence Family.
Additional streets running north and south were later cut through the blocks. Stedman Avenue was cut through between Myrtle and Primrose on the vertical line in Block C and goes all the way up to Hillcrest (Banana on this map). Acacia went in between North Primrose and North Magnolia, along the vertical lining running through the letters D and E on the map. It dead ends at Oaks Avenue which was cut through from Myrtle Avenue to Magnolia approximately along the southern boundary of the Monroe brothers' properties.
Melrose was laid down between Magnolia Avenue and J.I.C. Avenue running past Banana (now Hillcrest). There are several stories about the origin of the street name "J.I.C.". One story is that it was named after after J.I. Case, the farm implement manufacturer who bought property in the northern part of the subdivision and built a large house on it (Wiley 118). Another story is that the street was named after a racehorse that belonged to Mr. Case. Later the street was renamed Alta Vista Avenue.
