Take Action!
Washington Gas's current VDOT permit expires permanently in Jan 2026. They intend to start construction in Pimmit Hills in Apr 2026, but cannot do so unless they are able to successfully apply for another permit from VDOT.
There are three things you can do right now...
- Take minute to sign this Change.org petition: Stop Washington Gas from Routing Massive Pipelines Through Fairfax Neighborhoods
- NOTE: Share this with anyone in Fairfax County you think would be concerned about the Fairfax Circuit Court precedent from 2023 that Washington Gas can install any pipeline, no matter how large, under any street in the county, no matter how small, without any oversight from the county
- Sign on to three letters that PHCA will send to VDOT, the VA Attorney General's office, and the Fairfax Board of Supervisors about serious legal issues the PHCA Pipeline Committee has raised about the pipeline construction plans. Fill out Google Form: PHCA Washington Gas Action Fall 2025
- Volunteer to help the Pipeline Committee with door-to-door outreach for the 180 Pimmit homes along the planned pipeline route. Two ways:

What is the "Pimmit Pipeline"?
Washington Gas wants to complete their Tysons Strip 1 project by routing a massive transmission main (24" diameter, 325 psi) in a zig-zag route through Pimmit Hills. This pipeline will not serve the neighborhood, and will carry over 500 times more gas than the small service mains (2" to 4" diameter, <50 psi) already under our streets that actually serve homes.
There is a much more sensible option that is in line with the longstanding precedent of routing transmission mains under arterial roadways and with the best practice of combining major infrastructure projects to minimize disruption to the public: Fairfax County and VDOT are going to widen Route 7 in between 495 and 66 during the same time frame that Washington Gas wants to install the Strip 1 transmission main through Pimmit Hills (2026-2028).
Local elected officials, neighborhood leaders, and residents have urged Washington Gas and VDOT to combine these projects for over a decade! Fairfax County DOT has pledged to coordinate the project with Washington Gas and set aside a utility strip underneath one of the new Route 7 lanes for the Strip 1 pipe. And now that the Strip 1 project completion has been delayed five years from its original planned date of 2023... It is time to align these major infrastructure projects.
The PHCA Pipeline Committee has worked with local elected officials to lobby VDOT to make any permit for Strip 1 contingent upon routing the transmission main down arterial roadways. Please read Senator Salim and Delegate Simon's July 2025 Letter to VDOT to learn more and see links at the bottom for contacting your elected officials about it.

--->STOP THE PIPELINE <---
Washington Gas has obtained a permit to install a 24" diameter transmission pipeline THROUGH our neighborhood with construction expected to begin soon. We continue to fight and ask for your support.
A group of residents has pending legal action and is requesting donations for legal fees.
Please sign the Pimmit Hills Pipeline Petition to show your opposition.
If you live along the approved Pimmit Hills route, please take a quick moment to complete a brief survey, it will take less than 2 minutes.
Below is the approved route for reference:
Update 11/24/19:
Following the Washington Gas Community meeting in Oct '18 PHCA discussed the proposed route at a monthly meeting and the community and association at large determined opposition to the proposed route through Pimmit Hills and instead favors a route along Magarity Rd and Rt 7. PHCA created a Washington Gas Committee to oppose the proposed route. Currently, Washington Gas has been granted the necessary permits from VDOT to install the pipeline through Pimmit Hills with construction planned to start in Spring 2020.
Recently VDOT has granted Washington Gas a permit to install a pipeline through Pimmit HIlls despite our objection. Please sign our Pimmit Hills Pipeline Petition to show your support.
Also, we will host an information meeting Mon, Dec 9th from 6-7pm at the Tysons-Pimmit Library.

Update 10/13/18:
Washington Gas would like to change the pipeline path through Pimmit Hills from the Pimmit Hills Center to the existing regulator near Rt 7 / Pimmit via Peabody, Fisher, Cherri, Leonard, Cherri, Griffith and Pimmit. They are also studying a route which would be west on Magarity and south on Rt 7. Washington Gas held an information meeting with the community on October 3rd. Please refer to Washington Gas' website on the project for general project information, FAQ's, and the presentation from October 3rd.
