Hydrology and Geology
Phil Hardberger Park has the opportunity to be a living laboratory and model for sustainable technologies which demonstrate how the urban environment can be constructed in ways that benefit the environment, while counteracting the impacts of urbanization and impervious cover.
Both innovative and proven technologies for capturing, cleansing and reusing stormwater will be integrated into the Park structure, responding to the site’s ecology and ensuring the safety and welfare of the greater Phil Hardberger Park area by exceeding typical best management practices. Bioswales and acequias convey water through the site while cleansing it. Check dams along waterways slow and pool water decreasing the quantity of runoff and erosion. Ponds, wetlands and wet meadows function as points of collection and infiltration as well as storage for reuse in the Park. Cisterns at the Park buildings collect and store rainwater for building uses.
Park elements will not only address the surface water within the site but also water flowing from and to areas outside of the Park boundaries as well as deep beneath the site. As the Park is located within the Edwards Aquifer Transition Zone (EATZ), the potential exists that the capture and treatment of stormwater runoff will contribute to enhanced recharge of the underlying Edwards Aquifer. Water that once fl owed from and into surrounding neighborhoods will be held and treated on the site to help reduce runoff and flooding of nearby communities. Further studies involving watershed modeling and water quality analysis at source points on the site will be necessary to determine the parameters and design of water treatment strategies at the Park.
Phil Hardberger Park is also conceptualized to be a community paragon of resource stewardship; water elements in the landscape will allow people to experience and learn about the variety of ways the different forms of water can be cleansed and used on site and throughout the region. Water reuse will meet the needs of the Park in a manner that is compatible with the south Texas climate, setting a relevant example for regions with similar characteristics to San Antonio.
