Mitigation Banking and Long-Term Land Stewardship

GTA serves as the Bank Sponsor for the first federal agency Umbrella Mitigation Banking Instrument in Maryland, completed for the United States Air Force. We provide expertise in mitigation design, permitting, and construction supervision. We also hold mitigation sites and easements, managing them as the long-term steward. We have experience in setting up and working with long-term stewardship, endowment, and catastrophic event funds that support high quality stewardship or preserved lands, including completed mitigation banks and sites.

Horse Stall

Piscataway Headwaters Preserve

The PCMS is situated on a 63-acre portion of the larger Walton Foundation property (126 acres) that is adjacent to and within the 100-year floodplain of Piscataway Creek, which flows through the property from northwest to southeast.

Pheasant Run Preserve

GTA’s proposed Pheasant Run Preserve is in Baldwin, Maryland, a rural and mostly agricultural portion of Baltimore County. Located in the headwaters of the Gunpowder River, the 71-acre property is zoned agricultural and protected by a Rural Legacy Easement held by Baltimore County and Long Green Conservancy. Thirty-two acres of the farm is being actively restored, returning over 20 acres of wetlands and 5,000 feet of functional headwater streams to the property. GTA anticipates serving as the long-term steward of these important restored habitats that will help provide clean drinking water to residents in Baltimore City and County.


Wetland Creation

Maple Dam Wetland Preserve

GTA has an ongoing relationship with landowners in the Blackwater area of Maryland’s Eastern Shore (Dorchester County). In 2022, GTA helped to permanently preserve 42 acres of critical restored wetlands and wetland buffers, and we hope to double that acreage in 2023 and 2024.
