Marriott Hotel Redevelopment To Dump More Traffic at Key Bridge


Comments for Arlington County Board Meeting, March 24, 2020

I am speaking on my own behalf and not on behalf of the Transportation Commission of which I am a member.

Approval of the Master Transportation Plan for the Key Bridge Marriott site was heard by the Transportation Commission on March 5.

While I spoke in favor of the design, I abstained from the vote for want of an adequate traffic impact analysis (TIA).

Specifically I objected to the fact that traffic impact of three important pipeline developments was excluded from the TIA: Rosslyn Gateway, Rosslyn Plaza and the Ames Center at 1820 Fort Myer Drive.

Failing to report the impact of the latter site is egregious since the Transportation Commission heard that item on March 5 also, and a TIA for it has already been prepared.

The Ames Center alone will dump 630 vehicles from 788 new residential units on Rosslyn streets a block away from the Marriott. The redeveloped Marriott site will dump another 623 vehicles. The Holiday Inn site directly across the street from the Marriott will dump 818 vehicles housed in two garages.

These three developments could easily triple the amount of traffic at Lee Highway and Fort Myer Drive, an intersection that the TIA says is currently operating at LOS F.

According to the Marriott TIA, the combined impacts of the Holiday Inn and four other major developments in the immediate vicinity will generate 21,517 weekday trips exclusive of the Marriott (Table 5-1, p.44).

Rosslyn developers refuse to scale back the amount of built parking, even though Arlington County recommends doing just that. These developers evidently believe that they can’t market their luxury condos unless they provide at least 1 parking space per unit.

Will someone tell them that if buyers can’t get their car out of the garage, and can’t make headway on Lee Highway at rush hour, they will sell?Developers should focus on marketing spectacular views of the DC skyline, not the ability to park a car.
