Breewood Tributary Restoration

Stream Restoration

Along with projects to reduce and treat stormwater runoff flowing into the Breewood Tributary, the County has also completed a restoration project within the tributary itself.  The stream restoration project has stabilized 1,200 feet of stream channel from Sligo Creek Parkway upstream to the storm drain outfall located south of University Towers.

What are the Boundaries of the Stream Restoration Project?

The stream restoration project starts at the end of the rock lined section of the Fiesta Road Tributary. There was a five foot deep drop off or head cut in the stream channel which is where the restoration project begins.  A portion of the stream at the upstream end of the Fiesta Road Tributary is not included in the project as the stream channel in this area is stabilized with rock and not eroding.

The stream restoration ends at Sligo Creek Parkway near where the Breewood Tributary flows into Sligo Creek. 

 

How Will the Stream Restoration Project Help?

The stream restoration project will

• stabilize the banks to prevent erosion,

• add new trees and plants

• reduce the amount of sediment entering Sligo Creek

• improve water quality in both the Breewood Tributary and Sligo Creek

• reconnect the stream to its floodplain

• improve the ecological health of the Breewood Tributary and adjacent floodplain areas

The stream restoration project works in collaboration with the new stormwater management facilities being added in other areas of the Breewood watershed to capture and treat runoff before it enters the stream. New stormwater facilities have been installed along streets in the Breewood Manor Neighborhood and plans are currently in design for stormwater management facilities to capture and treat runoff from the University Towers Condominiums and the Northwood Presbyterian Church.

Breewood Manor Green Streets Projects

The Breewood Manor neighborhood is a single family residential area located on the south side of University Boulevard between Sligo Parkway and Dennis Avenue in Wheaton.  The Green Streets project area includes only a portion of the Breewood Manor neighborhood that drains into the Breewood Tributary, north of Gabel Street. 

DEP has identified eleven areas in the Breewood Manor Neighborhood to install Green Street projects along Breewood Road, Tenbrook Drive and Fiesta Road.  Green Street projects are roadway landscaping projects that reduce and filter stormwater runoff.  Green Streets include, grass swales and tree boxes, but in Breewood Manor, the Green Streets projects are rain gardens and bioretention facilities.

 

How Do Green Streets Work?

Rain gardens and bioretention facilities are constructed in between the sidewalk and the curb, within the public right of way, at locations that avoid interfering with utilities (water lines, sewer, gas, etc.). Once installed, these facilities will provide water quality treatment for most of the stormwater runoff that flows from the Breewood Neighborhood into the Breewood Tributary. Rain gardens and bioretentions are intended to capture stormwater runoff from the roadways in small garden like areas where the water filters through plants and soil before either exiting via an underdrain (bioretention facilities) or soaking into underlying soil (rain garden facilities).

In addition to the Breewood Manor Green Streets project, DEP is adding new stormwater management facilities in other areas of the Breewood watershed to capture and treat runoff before it enters the stream.  New stormwater facilities are being designed to treat stormwater runoff from parking lots at the University Towers and the Northwood Presbyterian Church.  Additionally, restoration of the Breewood Tributary will be completed to repair actively eroding stream banks and reduce the export of sediment into Sligo Creek and the Anacostia River.

University Towers Stormwater Retrofit

The University Towers is a 535 unit condominium complex located on a 12 acre parcel at the intersection of Arcola Avenue and University Boulevard in Wheaton. Approximately 5.3 acres of the property is impervious surface (parking lots, rooftop and sidewalks). Runoff from these impervious surfaces flows to a stormdrain system that exits the property to the south, under University Boulevard and into the Breewood Tributary. 

DEP has identified twelve areas on the University Towers property to install new stormwater management facilities (see map) which include rain gardens, bioretention facilities,  tree boxes and permeable pavers. These facilities, called Environmental Site Design (ESD) practices, will capture and treat stormwater runoff from small drainage areas or sections of parking lot.

Treatment of stormwater includes:

1. filtering pollutants from stormwater

2. reducing the overall volume of stormwater flowing from UT to the Breewood Tributary

3. promoting the infiltration of water into underlying soils to recharge groundwater supplies which help maintain stream flow in the Breewood Tributary during dry periods.  

Environmental benefits that these facilities provide will help improve conditions in the Breewood Tributary, Sligo Creek and the Anacostia River.

 

Working with University Towers and Residents

DEP is coordinating closely with the condominium association and the residents at University Towers to locate new stormwater facilities such that they do not interfere with utilities or community use of the property. A summary of proposed retrofit facilities ( PDF, 1.43MB) was prepared and distributed to the condominium association and residents. The summary provides information about the facilities, where they are proposed and how they function to provide water quality treatment for stormwater runoff. 

In addition to the University Towers stormwater retrofit project, DEP is adding new stormwater management facilities in other areas of the Breewood Watershed to capture and treat runoff before it enters the tributary. New Stormwater practices have been installed along streets in the Breewood Manor Neighborhood and plans are currently in design for a new stormwater management facility to capture and treat runoff from the Northwood Presbyterian Church parking lot. Additionally, restoration of the Breewood Tributary was completed in May 2015 to repair actively eroding stream banks and reduce the export sediment into Sligo Creek.

Northwood Presbyterian Church Stormwater Retrofits

The Northwood Presbyterian Church is located on University Boulevard, between Arcola Avenue and Sligo Creek Parkway in Wheaton. Approximately 1.0 acre of the 6.6 acre parcel is covered with impervious surface (parking lots, rooftop & sidewalks).

• Runoff from the smaller parking lot on the west side of the church and half of the rooftop drains off the property to the west into Sligo Creek.  

• Runoff from the larger parking lot on the east side of the church and half of the roof top drains off the property into the Breewood Tributary.   

   

DEP has identified a location at the south end of the large parking lot to install a new stormwater management facility (see map).  After collaboration with representatives from the church congregation, three types of stormwater facilities are being considered. Runoff from the parking lot will either drain to:

1. Bioretention: a garden-like area where the water filters through plants and soil before exiting via an underdrain.

2. Rain garden: a garden-like area where the water filters through plants and soil  

3. Conservation landscaping: native plant garden.

The type of facility chosen will depend on results from soils analysis.  

By capturing stormwater from the parking lot both the volume of water and flow rate is reduced which decreases the erosive impact to the Breewood Tributary. Additionally, pollutants are filtered out of the runoff which helps improve water quality in the Breewood tributary, Sligo Creek and the Anacostia River.

In addition to the Northwood Presbyterian Church stormwater retrofit project, DEP is adding new stormwater management practices in other areas of the Breewood watershed to capture and treat runoff before it enters the tributary.  New stormwater practices have been installed along streets in the Breewood Manor Neighborhood and plans are currently in design for stormwater management practices to capture and treat runoff from parking lots at the University Towers condominiums.  Additionally, restoration of the Breewood Tributary will be completed to repair actively eroding stream banks and reduce the export of sediment into Sligo Creek.

RainScapes Neighborhood: Breewood Manor

Breewood Manor was selected to be a RainScapes Neighborhood as part of the overall County effort to restore environmental conditions in the Breewood tributary to Sligo Creek. This neighborhood is receiving a higher level of effort and scrutiny as part of the MS4 permit requirements for restoration and monitoring. The combined efforts by the County on public land and the efforts of residents on private land are intended to restore the tributary to a healthier state and to reduce the volume of runoff and improve the quality of drainage from this neighborhood.

The residential property in the Breewood Manor neighborhood accounts for 46% of the developed area of the sub-watershed. The participation of private property owners in the neighborhood to reduce runoff that would otherwise flow from the private property to the stormdrain systems is an important part of the success of Breewood stream restoration efforts. The RainScapes program allows residents to become part of this restoration success by improving the "watershed friendly" function of yards with a new focus on sustainable landscaping practices. 

 

Retrofitting a Neighborhood

In many older communities, a combined retrofit effort, focusing on both public land and private property will maximize stormwater treatment potential. The stormwater retrofit approach in Breewood uses a combination of green infrastructure including rain gardens and rain barrels, Green Streets bioswales, a stormwater bioretention pond, and stream restoration.

The combined impact of retrofitting Green Streets and RainScapes projects is to reduce the volume of runoff and improve the quality of drainage from this neighborhood into Sligo Creek, while actively engaging residents in watershed restoration efforts. 

 

Breewood RainScapes Neighborhood Goal

Our goal in Breewood is to encourage between 10% to 30% of Neighborhood residents to participate, or between 5 and 16 homes. We are at a 5% participation level now, consisting of demonstration projects. (See map below)

Neighborhood Opportunities and Constraints

Yards in the neighborhood that drain to the Breewood tributary haev been evaluated for general RainScapes project suitability and potential. This evaluation looked at potential front yard space and drainage patterns from roof-tops and driveways. The evaluation was conducted from the public ROW - we did not need to enter private property for this phase. Of the 54 lots included in the assessment, 26 homes, or 48% have good potential for on-lot RainScapes projects. There are many opportunities for downspout disconnection - keeping roof runoff from running down the street by directing gutter downspouts into the yard rather than driveway.

RainScapes Neighborhood Process in Breewood Manor

The outreach effort in the neighborhood has included public meetings, field walks, telephone calls, and yard signs to inform residents about the program and solicit participation among neighborhood residents. Demonstration project installations began Spring 2014. 

A second round of RainScapes Outreach is anticipated to occur in the Winter of 2016, with a focus on County provided sire assessments and projects being installed using the  RainScapes Rewards Rebates approach. 

 

Site Assessment and Design

Residents who choose to participate in the RainScapes program are scheduled for a site assessment field visit on their property. At this field meeting, DEP staff or our contractor meet with homeowners to assess the nature of storm water drainage on and around the property, and where and how it could be treated on-site using a RainScapes project. Landscaping goals and preferences of the owners are also discussed at that time. Based on the outcome of the site assessment, recommendations are provided for a range of RainScapes projects that are eligible for rebate funding. 

The initial round of projects that are in the neighborhood were provided by the County and were intended to provide a demonstration in the community so that property owners could have close-by examples of RainScapes at work. At this time, we are able to offer site assessments for interested property owners in this neighborhood. Residents are encouraged to find out more about how to help the Breewood community and Sligo Creek watershed stormwater management effort in partnership with the RainScapes program. Please visit the RainScapes Rewards Website for information on the variety of RainScapes projects possible on private property.

Neighborhood Outreach

What causes the poor water quality in the Breewood Tributary?

Much of the damage to the Tributary is caused by stormwater runoff from the impervious surfaces in the surrounding community. 38% of the drainage area (24 acres) of the watershed is unable to absorb or infiltrate water. These impervious areas include roads, buildings, sidewalks, and driveways from which stormwater travels rapidly to the nearest storm drain and down to the stream.  Of the 24 acres, 15 acres have no stormwater management at all! 

It’s easy to see how this small tributary has been so severely impacted by runoff and erosion from uncontrolled stormwater.   

However, uncontrolled stormwater is not the only reason for degraded water quality in the Breewood Tributary.  The actions of those living in, working in and visiting the surrounding neighborhoods also play a role.  

Northwood High School students volunteered to pick up trash in the tributary

Human Controlled Actions Impacting the Watershed

Those who live in the areas that drain to the stream can make a conscious effort to improve the condition of the stream and watershed as well. Having residents recognize their role in the Breewood tributary’s improvement has been the focus of the outreach effort in this neighborhood.   

Actions that can impair water quality include:

• Not picking up pet waste

• Littering

• Using fertilizers or pesticides

 

DEP is working with residents living in the Breewood watershed to reduce waste, litter and chemicals in the waterways and implement methods to curb stormwater runoff. 

Pollution prevention activities planned in the outreach efforts include: 

• Community adoption of RainScapes practices

• Sustained community involvement in invasive plant removal and litter control in the Breewood Park 

• Gaining additional neighborhood stewardship including enhancing Breewood Park with benches and interpretive signs to increase its value as a local amenity. 

 

DEP began outreach efforts in the neighborhood in 2010 focused on these simple, yet effective watershed pollution prevention activities. This comprehensive project involved multiple partners, each with a significant role in educating and engaging the community. They included:

• Residents of the Breewood Manor neighborhood and University Towers condominiums

• Faculty and students at Northwood High School

• Members of the Northwood Presbyterian Church

• Friends of Sligo Creek and Neighbors of Northwest Branch watershed groups

 

RainScapes Targeted Neighborhoods

The RainScapes Targeted Neighborhoods program took on the role of identifying and addressing runoff impacts from yards, parking lots and landscaping in the area using techniques that focus on small-scale runoff management and pollution source control.  This activity involved partnering with the Friends of Sligo Creek (FOSC) watershed group and the Audubon Naturalist Society (ANS) to assist in assessment and community outreach. 

Through this partnership, members of FOSC & ANS assessed the potential for rain garden installation on the 70 residential properties that fall within the watershed boundaries. Once completed, 23 properties were deemed as having suitable conditions to install rain gardens. After this initial ranking, the partners set out to gauge interest, and installation approval from property owners.  

A goal of 30% approval was sought in the neighborhood and after several years of outreach, 3 property owners agreed to install rain gardens on their property (13%).  While the 30% goal was difficult to achieve, many positives came from this outreach. A few community members became advocates for the projects and helped to promote the community improvements and other activities. Several factors made the outreach effort challenging however, including language barriers, contacting appropriate property owners (renters vs. owners) and difficulties reaching households with owners that worked. 

FOSC was also very active in working with the Northwood Presbyterian Church on the importance of controlling runoff from the church property and its impact to the tributary.  The church worked with DEP and allowed for a rain gauge to be installed on the property to better examine rainfall trends in the area.

Creating a Community Trail

Starting in 2010, DEP’s outreach staff joined the effort and worked to establish regular cleanup events at the neighboring Breewood Park while the final 0.5 mile of trail was blazed.   Over the years, 227 community and school volunteers have donated nearly 700 volunteer service hours to this cause, removing 164 bags of trash and invasive plants from the watershed.  

 

Keeping the Community Informed and Engaged

Numerous outreach opportunities in the community have taken place in addition to the cleanups and trail creation.  From 2010 to 2014, DEP has hosted and partnered with other agencies and community groups in coordinating meetings, events, tours of the nearby Arcola Ave project and neighborhood walks highlighting the restoration efforts. National Trails Day, a 5K Bay Fun Run and Hike, and the Down County Consortium Cross Country Race are just of few of the community events that have taken place in the Breewood community to further engage the public in the project and the need for restoration.

Specific public meetings and neighborhood walks to engage the public have been organized at different stages of the project as well to keep the public informed of the status and progress of the project. Through all these community activities, meetings and events approximately 270 members of the public have been actively engaged in the Breewood tributary restoration over the past 4 years.  

University Towers

Portions of the Breewood tributary essentially start when rain falls on the 12-acre, 535-unit University Towers condominium complex property. Over the course of several years, extensive outreach was involved in educating the homeowners association’s board and residents about the project and why their involvement and acceptance of improvements was essential to the restoration effort.
