Merrifield Nursery Emergency Gravity Sewer ReplacementFairfax County
During a routine Closed-Circuit Television (CCTV) Camera inspection by Wastewater Collection Division (WCD), it was found that 45 linear feet of 8-inch asbestos reinforced concrete pipe (RCP) between MH-292 to MH-291 was within imminent danger of failing. The bottom of the RCP was missing within the 45 linear feet of repair and the pipe was on the verge of surcharging. After an immediate pre-construction meeting with Merrifield Nursery, it was agreed to work from 6pm-10am everyday of the week to avoid disruption and potentially placing patrons at risk during the biggest time of the year for Merrifield Garden Center. The contractor mobilized to the site and began the 20-foot excavation to replace 45 linear feet of broken gravity sewer. The project started on March 14th, 2022 and was substantially complete on March 23, 2022.
The Sully Basins Stormwater Pond Retrofits project was substantially completed on April 19, 2022. The project is located within the Cub Run watershed. The project consisted of repair and enhancement of multiple stormwater basins, 0326DP, 0964DP and 1484DP. The project also included construction of new stone cascades, stone weir basin structures and the construction of wetlands with high and low marsh areas. The project will facilitate improved sediment removal and improve downstream water quality using forebays and micro pools. Aquatic and natural habitat were also added within the three basins.
Clarks Crossing Road Improvements 05-13-22Fairfax County
The Clarks Crossing Road Pedestrian Access Improvement project improved the pedestrian and bicycle access along Clarks Crossing Road and was substantially completed on March 23, 2022.
This project completed the missing link between the existing sidewalk at Brookside Lane and the previously constructed sidewalk along Clarks Crossing Road. The scope of this project included construction of asphalt sidewalk, curb ramps, curb and gutter, drainage improvements along Brookside Lane and asphalt mill/overlay on Clarks Crossing and Brookside Lane.

Description:
The project consists of a new, 23,000 square feet, two-story, four-bay fire station facility and associated improvements to the 3.3-acre site including storm water detention, landscaping and parking. The scope also included the demolition of the existing fire station, and a temporary fire station to house the Fire and Rescue Department during construction of the new facility. The key elements of the overall project include:
Scotts Run at Old Meadow Road Park Phase I and Phase II Stream RestorationFairfax County
Scotts Run @ Old Meadow Road Stream Restoration was substantially completed on March 30, 2022. The Scotts Run project consisted of restoring, enhancement, and stabilizing of approximately 2,930 linear feet of eroding stream using Natural Channel Design criteria. This project included two phases: Phase I was funded by proffers from a private development and Phase II was County funded. Also included was the removal of invasive non-native plants and the installation of new plantings to stabilize the stream and floodplain.

LAKE BARTON DREDGING, RESTORATION AND RISER MODIFICATION PROJECT Fairfax County
The Lake Barton Dredging, Restoration, and Riser Modification project was substantially completed on December 29, 2021. The project is located within the Pohick Creek watershed. The project consisted of dredging and removal of approximately 19,100 cubic yards of sediment to restore the sediment trapping capacity and improve water quality. The project also included construction of new sediment forebays, in-lake haul roads, and riser modifications (new mid-level sluice gate and cold-water intake) to facilitate future maintenance, stabilize the shoreline, and improve downstream water quality. Fish habitat was also added within the lake.

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.

16. Stormwater Maintenance Awareness Training
MSMD/DPWES
Above Ground Facilities-Ponds (WP, DP)
• Common Remedies
– Algal bloom, turbidity, and water level inconsistent with plans (WP only)
• Investigate and resolve cause(s), if at all possible
– Remove all flow blockages as well as any additional trash, debris, and
accumulated sediment
– Repair/replace any damaged/missing components
• Components vary by facility type and design, and they can range
from parts (trash racks, well caps, etc.) to structural (walls, concrete,
etc.) to environmental materials (soil, gravel, etc.)
– Check approved site plans for specific facility requirements
16
17. Stormwater Maintenance Awareness Training
MSMD/DPWES
Above Ground Facilities-Ponds (WP, DP)
• Common Remedies
– Repair/replace any damaged/missing components (continued)
• For damaged/misaligned pipes:
– Reinforce/repair, if possible (Internal bands and gaskets)
– Slip-line pipes when possible, as this may be more cost effective
– Excavate and replace/reseal, if first two options are not possible
– Rebuild/stabilize any areas with erosion, cave-ins, and bare spots:
• Cave-ins require additional investigation to determine cause and
prevent re-occurrence
• Fill-in/stabilize any animal holes, per plan maintenance guidelines,
to discourage occupancy and re-occurrence
17
18. Stormwater Maintenance Awareness Training
MSMD/DPWES
Above Ground Facilities-Ponds (WP, DP)
• Common Remedies
– Cut back overgrown vegetation around facility structures to facilitate
access and proper function (WP/DP/WL have special requirements, as
noted below)
• Remove all trees and woody vegetation from the entire dam
embankment: face, back, top, etc.
– Check plans for a ‘Planting Plan’ which may have allowed
plantings on the dam embankment
• Remove overgrown vegetation
– Within 10’ of control structure
– Within 5’ of all other structures
– Within inflow/outlet channels
– Other areas, as needed, for facility access

treatment by providing an ideal
environment for:
– Long residence time
– Gravitational settling
– Biological uptake
– Microbial activity
• Stormwater management benefits:
– Nutrient load removal and
reduction
• Nitrogen

MSMD/DPWES
Above Ground Facilities-Wetlands (WL)
Deficiencies Requiring Action
• Clogging of pipes from sediment, vegetation and debris
– If low flow orifice is clogged, it can result in a rapid change in
wetland water elevations.
• Sedimentation accumulations in forebays and micropools
• Erosion and braiding (channel separation and intermixing,
sometimes with formation of deposited bars or islands)
• Vegetation Issues
– Growth over access points
– Invasive species
– Dead, dying, missing vegetation
– Bare spots
– Trees and woody vegetation on dam embankment
22
23. Stormwater Maintenance Awareness Training
MSMD/DPWES
Above Ground Facilities-Wetlands (WL)
• Common Remedies
– Remedies are the same as for WP/DP (please refer to slides 16-18)
– Additional vegetative concerns specific to wetlands:
• Remove any non-spec vegetation, especially if it impacts the health
and function of the facility, as designed
• Replace/replant any dead, dying, or missing wetland vegetation per
approved site plans
