• South Dakota Ave is a 3.6-mile arterial roadway
  • Driver behavior on this roadway is extremely bad, with rampant speeding and red-light running among other problems
  • Residents of the roadway, organized as Friends of South Dakota Avenue NE (FoSDANE) are fighting for a safer road by design
  • Dedicated funding in Fiscal Year 2024 could begin the process of making these changes
  • We need to keep up pressure on Council Chair Mendelson to make sure the Transportation Committee allocation makes it into the final budget
  • We also need to provide feedback to WMATA to advocate for two proposed brand-new SDA bus lines: currently dubbed DC214 and DC207

FY24 Tactical Safety Funding

The (not yet final) FY24 budget contains $1M in funding for tactical safety improvements on South Dakota Ave. Tactical improvements generally:

  • involve flexposting and concrete curbstops to modify traffic patterns
  • don’t modify curb or other concrete components of the roadway, which requires costly construction and analysis of issues like drainage
  • can provide an outline for future more permanent changes, like a pencil sketch to be colored in later

An example of a tactical safety project of this kind is the late 2022 improvements made to New Jersey Ave from N St NW north to Rhode Island Ave NW. You can see the Notice of Intent issued by DDOT in May 2022 for that project.

budget process/history

Since the beginning of the FY24 budget process, the issue of funding safety improvements to South Dakota Ave has been a high priority of mine, Councilmember Parker, and the Councilmember’s team. Efforts by FoSDANE during the budget process

early letters

In a February 3rd email to Councilmember Parker’s team, I wrote in part:

My other major ask is that dedicated funding be included for large-scale whole-corridor studies of our principal arterial roadways, including Rhode Island, South Dakota, and New York Aves. I believe the ongoing work on Bladensburg Rd, from Starburst Plaza all the way up to Eastern Ave, is a good example of the scale and scope such a project requires (especially should the final designs more closely align with Concept One). Meanwhile, the other three major arterials surrounding my SMD are in need of fundamental redesigns that prioritize those in our neighborhood over those only driving through it, and all have been the subject of studies that have not resulted in major implementation

I also mentioned the mobilization of efforts of South Dakota Ave residents that would become the Friends of South Dakota Ave NE:

Residents of South Dakota Avenue have mobilized, forming an initiative for action that has grown in short time, and has residents from Riggs Park to Fort Lincoln, intent on raising the need to make South Dakota Ave a less violent and more welcoming corridor.

In Councilmember Parker’s February 16th letter to the Mayor on budget priorities, he wrote:

…I am eager to partner with DDOT to improve many other dangerous arterial corridors in Ward 5, including South Dakota and Michigan Avenues and the other Ward 5 high-injury corridors identified the 2022 update to the Vision Zero Plan. I request that you direct DDOT to leverage existing operational funds to improve safety on these corridors as expeditiously and aggressively as possible.

DDOT Performance Oversight and Budget Oversight hearings

Sherin Koshy of FoSDANE testified before T&E to the urgency of safety improvements to South Dakota Ave at the 2/27 Performance Oversight and 3/30 Budget Oversight hearings. Chris Leis additionally testified at the 3/30 Budget Oversight hearing.

Mr. Leis testified, in part:

South Dakota Ave (SDA) is a primarily residential street that gets treated like a highway by drivers and their behavior is enabled by the negligence of DDOT design and lack of enforcement by MPD. Unfortunately, this is not a new issue and according to a 2007 DDOT study this street suffers from more than just reckless drivers and “throughout the corridor, complex multi-approach intersections, faded and inconsistent pavement markings, and inconsistent signal timings contribute to a degradation of safety for pedestrians, bicyclists and vehicles.” These issues were identified over 15 years ago and I’d be hard pressed to find one of the recommended solutions that has been implemented, except additional speed limit signage and that was done just last year, after over a year of TSI requests and direct involvement from ANC 5c. Prior to the additional signage in 2022, there were 2 (not a typo) speed limit signs in the 1.5 mile stretch between New York Ave NE and Rhode Island Ave. The lack of signage and the deteriorating road conditions point to clear neglect from DDOT and something that should be remedied in the FY24 budget.

The speeding along the SDA was also evident in the 2007 report and showed an 85th percentile speed that is 80% above the posted speed limit. Now, that might be considered an old study, which is fair, but a 2021 study on the 3000-3100 block of SDA confirmed that 80% of all vehicles were still speeding and that the 85th percentile speed is still 40% above the posted speed limit.

ANC resolutions

On March 15th, ANC 5B unanimously passed a resolution reinforcing Councilmember Parker’s asks. Among other things, this included resolution “to leverage existing operational funds to improve safety on South Dakota and Michigan Avenues”

A similar resolution was introduced in ANC 5C the same night, but was tabled by a 4-2 vote.

T&E Committee markup and draft report

Thanks to the stewardship of Councilmember Parker and Chairperson Allen, the following was added to DDOT’s budget during markup by the Council Committee on Transportation and the Environment (T&E):

$1 million for the installation of tactical road diets along South Dakota Avenue NE to help slow down cars down the residential corridor;

More details, per the draft Committee report released April 26th:

The Committee is also establishing a new sub-project within DDOT’s Safety & Mobility master project to fund tactical safety improvements on South Dakota Avenue NE. South Dakota Avenue is one of the most dangerous corridors in Ward 5. However, due to the presence of even more dangerous arterial corridors in Ward 5, South Dakota Avenue NE was not designated a high-injury network corridor in DDOT’s 2022 Vision Zero Report. The Committee is placing $1M in the new sub-project to fund efforts to improve safety on the corridor in the short term, preferably by constructing a road diet on a segment of the corridor to calm traffic, reduce injuries, and improve connectivity along the corridor. DDOT shall determine which segment of the corridor would be a suitable starting point for safety improvements; however, the Committee recommends that DDOT consider either the segment between Bladensburg Road and Monroe Street NE or the segment between Sargent Street NE and Riggs Road NE.

May 11th Site Visit

On May 11th, Councilmember Parker and DDOT Director Everett Lott conducted a site visit and walk along South Dakota Avenue. Members of FoSDANE and many ANC Commissioners representing the roadway (including myself) were present.

Committee of the Whole action

On May 15th, Council Chair Mendelson introduced his proposed budget to the Council Committee-of-the-Whole. A forthcoming letter from FoSDANE will thank him while emphasizing the need to keep this dedicated funding in the FY24 budget as it proceeds to the whole Council.

Better Bus Network Redesign

There are two new major bus lines proposed as part of Better Bus Network Redesign, which reimagines our bus service for modern needs:

  • DC214 (24-hour Fort Lincoln/SDA/RIA/downtown line)
  • DC207 (all-day bus line running from Fort Totten to down past Fort Lincoln, covering the entirety of South Dakota Ave)

Folks can provide feedback on the importance of these lines making it into the final set of recommendations.

roadway history

Part of moving forward is understanding how we got here.

South Dakota Avenue is entirely outside of the original City of Washington designed by Pierre L’Enfant, and has no origins in that plan. By 1898, it appears in the DC Permanent System of Highways master planning document, which implemented Congressional directives to extend the logic of L’Enfant’s plan outward to the entire District of Columbia. Some more historical map artifacts on the piecemeal construction below.

1898 The full length of SDA (minus link to NYA/50) appears in DC’s Permanent System of Highways; a segment from Irving to Bladensburg appears to overlap with the ring road connecting Civil War forts LoC
1903 Named Prospect Ave, the only segment of what would become SDA exists between Vista and Brentwood Road (at a segment later becoming part of Rhode Island Ave). Baist/LoC

1954 New York Avenue is extended from Bladensburg Road to US-50, presumably joining in South Dakota Ave.
