<1800's - Before European settlers arrived to the area, the land that is now Memorial Park, like all of Houston, was Gulf Coast grassland prairie, wetlands, and savanna with riparian forests. The land was subjected to natural disturbance such as fire from thunderstorms and grazing from the great bison herds that moved across North America. These natural events maintained open grasslands and savannas across the region. Indigenous peoples like the Karankawa continued to preserve open grasslands through controlled fire as part of their agricultural practices.

1800's - As settlers arrived to the area in the early 19th century and the cities of Harrisburg and ultimately Houston were established, the first homestead was built along Buffalo Bayou in what is now Memorial Park. Along with it, ranching, farming, logging operations, and a brickmaking factory were all established in and around the present day park boundaries.

1917-1919 - Camp Logan is open as a U.S. military training facility during World War I. The plat shows the estimated locations of roadways and structures within the present day Eastern Glades.

1930's - The first master plan for Memorial Park is created by landscape architecture firm Hare & Hare. The plan calls for a loop road through the park and a round gathering area in the eastern portion of the park.

1940's - By 1940, implementation of the initial Hare & Hare Master Plan has begun with construction of a loop road, golf course, and ballfields.

1950's - In less than 30 years, much of the park that was open grassland in Camp Logan has turned into dense forest. The removal of land management techniques such as grazing, mowing, and prescribed fire allowed forest species to grow and expand.

1970's-1980's - The Seymour Lieberman Trail is built within the original Memorial Loop Road and through Eastern Glades. The forest canopy continues to fill in, however evidence of original Camp Logan roads remain.

2000 - By the turn of the 21st century, better technology in landscape monitoring become more available.

2011 - Severe drought gripped much of Texas in 2011, including Memorial Park. Over half of the trees in the park die because of drought, including many in Eastern Glades.

2014 - Development of a new master plan begins, including creating the Eastern Glades project.

2016 - Initial surveys of the Eastern Glades were completed and ground was broken on Phase 1 of the new project.

2017 - Phase 1 of the Eastern Glades project is well underway with new parking and restrooms being built.

2018 - Phase 1 is completed and with funding for Phase 2 is secured, construction begins.

2019 - Construction of Phase 2 of Eastern Glades begins.

September 2019 - Eastern Glades and Hines Lake is put to its first test when Tropical Storm Imelda drops 6" of rain in just a few hours on the site. The lake fills, but does not overflow the lake edge.

December 2019 - Installation of the Zoysia turf in the Oval begins.

Summer 2020 - Final work begins in Eastern Glades to prepare for opening.

July 2020 - Eastern Glades officially opens!
