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.

Reston Arts Center Feasibility - Focus Group Visual ArtsFairfax County
These community outreach meetings are being conducted to understand community needs for a proposed arts venue in the Reston Town Center.
The proposed arts center would be a result of a proffer from Boston Properties in the next phase of Reston Town Center development (Block J).
The proffer would provide for an approximately 60,000 gross square foot facility to house a stage suitable for large-scale music and dance performances, as well as other arts-related amenities.
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.

Vegetative Practices-Bio-Retention (BR)
• Collects both piped and surface
runoff into a shallow landscaped
depression incorporating pollutant
removal mechanisms, filtration,
and infiltration characteristics
which mimic pre-development
conditions
– Infiltration is through a filter
bed of sand, soil and organic
material.
– Filtered runoff may be
returned to storm system via
an underdrain and/or
infiltrated into surroundings.
