The same is true for mail sent to University Park.HistoryThe land now known as Highland Park was bought in 1889 by a group of investors from Philadelphia, Pennsylvania, known as the Philadelphia Place Land Association, for an average price of $377 an acre, with a total of $500,000. Henry Exall, an agent, intended to develop the land along Turtle Creek as Philadelphia Place, exclusive housing based on parkland areas in Philadelphia. He laid gravel roads, and dammed Turtle Creek, forming Exall Lake, before the Panic of 1893 brought a blow to his fortunes, halting development. Afterwards, he began a horse breeding farm. In the 1890s, Exall Lake was a common picnic destination for Dallas residents.
