south river restoration

The South River Federation received a $35,000 grant from the Chesapeake Bay Trust for a stormwater Best Management Practice (BMP) series at the Annapolis Subaru dealership. This project was designed to alleviate stormwater flows across two commercial properties before the runoff enters the top of our large-scale "Church Creek Headwaters Project," which begins just 500 feet downslope of Annapolis Subaru.                                

The stormwater retrofit plan reduces the approximate 199,923 gallons of runoff which reach the Subaru site in a 1 inch rain event. The BMP series was designed to capture and infiltrate runoff starting at the most upstream property line at the Medical Center. BMP #1 is an infiltration swale which addresses off-site runoff and slows down and infiltratse the volume which goes into the existing pipe. Midway down, a large, sunken swale was converted to into a bioretention cell for BMP #2 where ponding and infiltration of the runoff can occur. The existing pipe daylights at the lowest point of the Medical Center property (and beginning of the Subaru property) where BMP #3 is located. The proposed BMPs are crucial to the reduction of volume which carries significant sediment loads to the headwaters.

Volunteers from the community, Bywater Boys and Girls Club, and the Department of Corrections Public Safety Works crews help to plant and mulch the project site.

Featured Projects

  • Annapolis Harbour Center Stream and Wetland Restoration

    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...

  • Broad Creek - Health Department Gully Restoration Phase 1

    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...

  • Church Creek Headwaters Restoration

    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...

Current Projects

  • Bacon Ridge Natural Area

    Background: The Bacon Ridge Natural Area (BRNA) is a County owned Natural Area in Crownsville, MD. The area consists of over 700 acres of forests, streams, and wetlands, including portions of the Crownsville State Hospital property. The Federation strongly advocated for the permanent protection of new...

  • Beards Creek: Killarney House & Neighbors Community BMPs

    Killarney House Stream Restoration Project With "Live Green, Eat Irish" as their motto, a roof covered in solar panels, and a small farm out back, the Killarney House Irish restaurant is committed to being environmentally responsible. In 2015, Killarney House owner Anthony Clarke reached out to...

  • Broad Creek - Health Department Gully Restoration Phase 2

    This restoration project will restore stability and functions to a 750  linear feet ephemeral gully that flows to the East Branch of Broad Creek. Like the nearby gully restored in May of 2018, this channel is highly unstable and leading to excessive delivery of sediment downstream during even minor...

  • CAT - South Rain Garden

    The Federation is constructing a stormwater bioretention cell on the campus of the Center of Applied Technology – South (CAT-South), a magnet program of Anne Arundel County Public Schools (AACPS) located in Edgewater, Maryland. This project will address flooding issues experienced outside one of...

  • Gravely - Kings Branch 'Grand Canyon' Restoration

    Flat Creek's "Gravely Grand Canyon" is one of the fastest eroding tributaries in the South River watershed, with over 11,000 linear feet of highly incised and unstable channels.

  • Holly Hill Harbor Restoration

    The project was identified by the West/Rhode Riverkeeper for retrofits due to the frequent high bacteria levels that were found in weekly bacteria samples conducted just outside of the property. These elevated levels highlighted the need to prevent polluted stormwater from entering the river.

  • Living Shoreline Projects

    The South River Federation has worked with a number of communities on the River to replace bulkhead and revetment with natural “living shoreline” projects. These projects rely less on structural materials, such as rock and lumber, for stabilization, and instead work with the wave energy on the...

  • Turnbull Estates BMP & Living Shoreline Project

    South River Federation (SRF), in partnership Turnbull Estates community, Edgewater, MD, is seeking to couple a community bioretention project with an innovative living shoreline restoration approach, utilizing the native oyster Crassostrea virginica along with conventional methods (segmented sills)....
