Green Infrastructure Examples for Stormwater Management in the Hudson Valley

Use the links below to view examples of stormwater management projects in the Hudson River Valley that use green infrastructure.

Green infrastructure practices maintain or restore stormwater's natural flow pattern by allowing the water to slowly permeate into the ground and be used by plants. These practices include rain gardens, vegetated swales, green roofs and porous pavements. Green infrastructure also includes preserving or restoring natural areas, such as forests, stream buffers and wetlands, and reducing the size of paved surfaces. Green infrastructure generally includes "better site design" or "low impact development" stormwater projects.

In addition to managing stormwater, green infrastructure can recharge groundwater, provide wildlife habitat, beautify neighborhoods, cool urbanized areas, improve air quality and reduce stress on combined sewer systems.

The Hudson River Estuary Program recently conducted a survey on barriers to green infrastructure implementation in the Hudson Valley. We received 127 completed responses from a wide range of green infrastructure practitioners. Respondents cited cost, lack of knowledge, and resistance from local, municipal officials as the top barriers to implementation of more green infrastructure. For more detailed information, see the Barriers to Green Infrastructure in the Hudson Valley report (PDF) (890 KB).

As part of the Hudson Estuary Watershed Resiliency Project, SUNY New Paltz has constructed several green infrastructure practices, conducted water quality research and monitoring, and focused classes on local water issues. This short documentary describes the collaboration, and how green infrastructure can help the campus and the village improve watershed resiliency to climate change.

Rain Gardens

of the Environment office in Kingston.

Rain gardens manage and treat small volumes of stormwater by filtering runoff through soil and vegetation within a shallow depression.

Bioretention Areas

Bioretention areas capture and treat stormwater, allowing the water to filter through soil and vegetation. Bioretention areas are usually larger than rain gardens and designed with an underdrain to connect to the storm drain system.

Vegetated Swales / Dry Swales

in Orange County.

Swales are natural drainage paths or vegetated channels used to transport water instead of underground storm sewers or concrete open channels. They increase the time of concentration, reduce discharge, and provide infiltration.

Green Roofs

Green roofs are layers of soil and vegetation installed on rooftops that capture runoff. The vegetation allows evaporation and evapotranspiration to reduce the volume and discharge rate of stormwater.

Porous Pavement

Community Library in Copake.

Pervious types of pavements allow stormwater to infiltrate through the surface, reducing stormwater runoff and some pollutants.

Stream Buffer Restoration

the Hudson Estuary Trees for Tribs initiative.

A healthy vegetated buffer helps improve stream health and water quality by filtering and slowing polluted runoff, along with many other benefits.
