Week of September 30, 2019

This Monday, September 30, water service near the development site will be temporarily shut off as the installation of water, sanitary and stormwater lines is completed. This is expected to affect surrounding buildings between 9:00 p.m. and 12:00 midnight, but service will be restored as soon as possible.

Underground utility work along Woodmont Avenue, which began in March of this year, is expected to be finished in October. This work is currently being performed during daytime hours. Following the completion of this work, the section of Woodmont Avenue adjacent to the construction site will be patched and restriped.

Meanwhile, underground utility work along Wisconsin Avenue continues during nighttime hours and is anticipated to be completed in November. As the development team is sensitive to community feedback related to noise during nighttime hours, the majority of saw-cutting of the roadway will be taking place exclusively during daytime hours to minimize impact to the adjacent residential properties. Related road restoration work is being performed during daytime hours. A timeline for each phase of the underground utility work is estimated in this site plan.

Along Wisconsin Avenue, concrete pouring operations continue with concrete placements scheduled for Tuesday and Friday this week beginning at 5:30 a.m.

Throughout this project, the approved Montgomery County and State Highway traffic and pedestrian control plans will ensure minimal impact to traffic flow around the construction site. Meanwhile, sidewalk closures remain in place along sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here). Based on recent community feedback, new and enhanced traffic and pedestrian control plans have been submitted for review. We anticipate these new plans will be approved and implemented in October.

Our number one priority is the safety and security of commuters and pedestrians around the construction site. During this time, please be vigilant and pay close attention to detour signs and flagging operators as they direct traffic to minimize disruptions. Failure to follow these directions may risk your safety or even result in a citation from local law enforcement.



Monthly construction updates

The development team is committed to an open dialog with the community and holds bi-monthly construction updates open to the general public. These updates are generally scheduled for the first Tuesday of every other month and take place in downtown Bethesda at the Bethesda-Chevy Chase Regional Services Center located at 4805 Edgemoor Lane, Bethesda, MD 20814.

You are invited to attend the next update this Tuesday, October 1 at 6:00 p.m.
