December 4, 2023 Community Meeting Recap

GreenVest hosted a second, virtual public meeting on December 4th to provide residents with updates on the stormwater facility retrofit project at Oxford Crossing. Members of the project’s engineering, design and construction teams joined GreenVest’s Project lead to:

• Review County stormwater quality goals and requirements related to the Oxford Crossing project.
• Provide summaries of project work and progress to-date.
• Provide an overview of updated design and construction plans.
• Share the County DEP’s long-term maintenance requirements and approximate cadence.
• Confirm approximate schedules for ongoing planning and future construction.
• Discuss opportunities to walk the site with the team before and after construction.

Residents can also message to speak with directly with the project team or request this information in a different language.

December 4th Question & Answer

Will there be opportunities to visit similar projects in the area?
Yes. We are working with community members and the County to facilitate a site walk at a representative/similar project in the area and will provide updates on the project website. While Montgomery County has completed several retrofit projects (wet ponds and dry ponds), the retrofit at Oxford Crossing will be its first SGSMS of this exact scope and scale. Residents can also click here to find nearby watershed restoration projects in Montgomery County.

Will there be ongoing noise related to SGSMS functioning once construction is complete? Does the system run 24 hours a day, seven days a week?
No. As a “passive system,” the SGSMS will not emit noise. There are no electrical pumps or anything mechanical related to the system. Instead, the SGSMS works naturally to remove pollutants from stormwater as it flows through gravel media and native plantings.

What happens when debris collects in the system. Who should be contacted to address structural issues like this?
GreenVest provides a one-year guarantee on the completed SGSMS. During this time, the facility will be inspected regularly to assess its functioning, remove any sediment or invasive plant species and reseed or replant vegetation as necessary. The HOA retains perpetual maintenance of non-structural components including trash/debris removal, mowing in grassed areas, and preventing the establishment of trees on the embankment. After the first year, Montgomery County will be responsible for inspecting the facility at least once every three years to assess and address any required structural maintenance including filter media and wetland vegetation management and subsurface sand/gravel maintenance.

Residents can contact the Montgomery County DEP’s Stormwater Management BMP Maintenance and Inspection Program to submit a service request or otherwise communicate questions or concerns related to the SGSMS system, after which the DEP will investigate and provide remediation as required. A “Service Request” can be submitted online here or residents can call 311 (240-777-0311) between 7am and 7pm on weekdays.

What will the long-term cost of maintenance be for the County?
The plan and budget for long-term maintenance of County stormwater management facilities is an established function of County government and a responsibility within its MS4 permit, which is mandated and overseen by the state and Federal governments to meet established water quality improvement goals. However, because of the SGSMS’s biological design and natural functioning, the labor required to maintain its effectiveness and visual aesthetics are typically lower than for other stormwater management systems.

Will the SGSMS attract birds? Have there been complaints of bird droppings on cars?
Migratory bird species tend to find refuge and sustenance in the microhabitat established within a SGSMS, drawn in part by its flowering plants and the healthy native insects these attract. Birds tend to remain within in the established habitat, rather than venturing to more populated areas like parking lots or roads. GreenVest is not aware of complaints regarding bird droppings in relation to this type of facility.

What’s next?
The design and permitting process is currently underway including coordination with County, state, and federal agencies. This will include finalizing planting plans in coordination with the OCCA. Construction is scheduled to begin in early 2025 and is expected to last three to five months. Residents will be invited to attend a pre-construction field walk in late 2024 or early 2025, as well as a post-construction field walk once the SGSMS is complete.
