south river restoration

Featured Projects

This restoration project restored stability and functions to a 950  linear feet ephemeral gully that flows to the East Branch of Broad Creek.  The channel was highly unstable, leading to excessive delivery of sediment downstream during even minor storm events. By stabilizing the gully and constructing additional upslope stormwater detention and infiltration devices in the parking lots, the Federation stopped a significant source of sediment and nonpoint source pollution from entering Broad Creek. The project was constructed by Resource Restoration Group in May 2018.

The Annapolis Harbour Center Stream and Wetland project improved habitat, increased floodplain connection, and prevents bed and bank erosion. This particular project focusesd on controlling flows and providing habitat at the bottom of existing outfalls, through the use of a step-pool storm conveyance (SPSC) in ephemeral reaches (where water flows only after rain event) and riffle weirs and buried grade control structures in the intermittent and perennial reaches (year round flow).

There are four primary tributaries feeding Church Creek, one of the most highly degraded sub-watersheds on the South River.  One of them, the Wilelinor Stream Valley was restored in 2003 by Anne Arundel County and the Maryland State Highway Administration using sand seepage stream and wetland restoration techniques. The goal of this larger subwatershed restoration effort is to take the necessary steps to repair the other tributaries to Church Creek, using similar restoration methods as well as pond retrofits, upland bioretention practices, and living shoreline techniques to create a model sub-watershed restoration, and evaluate the impact of such cumulative work on the South River.

The Church Creek Headwaters Restoration Project is located just north of Route 665 (Aris T. Allen Boulevard) in Annapolis on a parcel that includes several acres of floodplain and steep slopes. The site represents the confluence of two major non-tidal tributaries to Church Creek, the most highly urbanized subwatershed of the South River. Currently, these tributaries are incised into a floodplain composed of over ten feet of aggraded legacy sediments that are exported to tidewater under storm flows through the rapidly eroding (widening) ditch channels. This project created several acres of stream and wetland habitat by raising the invert of the existing ditch channel in multiple locations and inundating or saturating the floodplain.

Anne Arundel County's Phase II WIP listed this site as moderately degraded and a high priority for restoration.  It is listed in our 2008 Watershed Restoration Plan as one of 30 high and medium priority restoration projects.
