Wetland Mitigation at Evangola State Park

In 2010, the NYS Thruway Authority planned to make much needed improvements to I-90 near Irving, NY, a project which would inadvertently affect about 2 acres of emergent marsh wetlands in the area.

In order to mitigate these adverse impacts on the marsh habitat, the NYS Thruway Authority teamed up with Evangola State Park and Watts Architecture & Engineering by reclaiming a dry, rocky, flat fill area and transforming it into a valuable and productive habitat.

Taking advantage of the area’s natural hydrology and terrain, landscape engineers created a three acre wetland along Evangola’s entrance parkway. This new habitat feature is home to various amphibian, reptile, and fish species, as well as a nesting and foraging site for a variety of birds and ducks.

Wetlands play a very important role in the environment, including ecosystems services that are valuable to humans. Wetlands act as water purification system, flood control, and they improve the stability of shoreline. Wetlands are also often the most biologically diverse ecosystems in a region, serving as home to a wide range of plants and animals. In New York, wetlands are used as stopovers for migrating birds, as a breeding habitat for migratory birds and other birds that nest in wetlands, and as a winter home for many amphibian species.

The human-made wetland at Evangola also presents various opportunities for educational ecological study to school groups, summer camps, and scout troops that visit the park. A hands-on outdoor classroom allows students to gain first hand experiential knowledge of this important ecosystem type.

The beautiful wetlands, finally completed.

The project’s overwhelming success prompted the American Council of Engineering Companies of New York to Award the Wetland Mitigation project at Evangola State Park the Gold Award for Engineering Excellence to the New York State Office of Parks, Recreation & Historic Preservation, the first landscape project to ever win this prestigious award. The award was a nod to the project’s excellent design, and the educational opportunities it created.
