Redeveloping DC’s McMillan Sand Filtration site will not choke neighbor­hoods in new traffic as long as the District follows through on transit plans, says a transportation study from the project team.

The most important element: better transit

The study says that it’s quite possible to avoid burdening busy roads in the surrounding neighborhoods, as long as planned improvements to transit actually happen. The report says is transit is actually necessary regardless of whether the project goes forward or the site remains fenced off.

In the short run, improving the Metrobus 80 bus line on North Capitol Street, which WMATA has already designated a “bus priority corridor,” will help the most. Other bus lines also need improvements that previous studies have identified.

The report also calls for building the proposed streetcar line along Michigan Avenue from Woodley Park to Brookland Metro. If these projects get delayed, he report recommends coordinated shuttles to the Brookland Metro station.

Along with some tweaks to surrounding roads, the traffic will be no worse with the McMillan project than if nothing gets built.

The report also calls for better bicycle and pedestrian infrastructure, including completing the street grid through McMillan, multiple pedestrian access points in each building, ample bicycle storage, and space for three Capital Bikeshare stations.

Pitfalls remainWhile the study demonstrates the redevelopment can move forward without burdensome traffic impacts, it also points to potential problems that the project team will need to take care to address.There needs to be ongoing pressure on the city and DDOT to move forward on transit. The city has moved slowly to upgrade transportation elsewhere, so project partners need to keep a close eye on progress.Walking and bicycling conditions on and off the site also need more attention. Busy driveways on Michigan Avenue pose potential new conflict points for pedestrians and bicyclists. As the city reviews this project, it should take every chance to improve access and safety in the area. Also, while it’s great to leave space for three Capital Bikeshare stations, the development should pay for at least one.The transportation plan specifically cites a proposed DC Circulator route from Brookland to Tenleytown, which covers the same ground as the current H buses. Instead of duplicating existing service, DC and Metro could work together to improve existing H bus service. In fact, Metro recently studied the H lines and made several recommendations to make service faster and more reliable through the area.New traffic signals will help pedestrians and bicyclists, but the added turn lanes and driveways on Michigan Avenue and First Street NW could pose additional barriers and hazards.The report also recommends incentives to reduce driving, lower vehicle parking ratios, and encourage transit use in later phases. Instead, these efforts should start now.With a redevelopment as large and controversial as McMillan, it’s important to push for the right policy decisions.
