Stream restoration improves water quality in the Chesapeake Bay watershed

Ecosystem Investment Partners is financing and building stream restoration to provide Maryland state and county entities with high quality nutrient and sediment reduction offsets to help them meet water quality requirements.

The Maryland Water Quality projects are large-scale stream restoration sites operated by EIP – a leading provider of environmental credits. The Maryland Water Quality projects include 412 acres of private land in Cecil County.

Under the Clean Water Act, various Maryland municipal entities are required to offset storm water, nutrient and sediment discharges to the Chesapeake Bay under their National Pollution Discharge Elimination System (NPDES) permits. These entities are now seeking to acquire their required offsets from private firms like EIP which can deliver proven outcomes like those that permittees obtain when acquiring mitigation credits under Section 404 of the Clean Water Act.

EIP has contracted with the State of Maryland’s Bay Trust Fund to deliver 94,825 linear feet of stream restoration within the Principio Creek watershed in Cecil County, Maryland. The total anticipated reductions from these projects are 32,962 pounds of nitrogen, 3,122 pounds of phosphorus and 3,166 tons of sediment per year.

EIP additionally contracted with the Maryland State Highways Administration to deliver 52,245 linear feet of stream restoration in Cecil County.

Restoration Initiative

The Maryland Water Quality projects include six properties with a total of 94,825 linear feet of stream. EIP is restoring important ecological functions to the degraded streams on these active farms. Before EIP’s initiative, the artificially straightened channels, active erosion, and degraded or non-existent riparian buffers severely impacted the water quality and habitat value of these streams and the Chesapeake Bay watershed.

EIP has restored a more natural pattern, profile and dimension to these badly degraded streambeds, bringing back a meandering pattern with a stable channel configuration that is permanently protected with a conservation easement. This work provides the continued benefit of reducing downstream sediment loading and the transport of nitrogen and phosphorus into the Chesapeake Bay.
