Beacon Hill may continue to be a Blue Bikes desert even as the Transportation Department expands its bikeshare network downtown.

Planners have completed three open houses polling residents of Beacon Hill, Chinatown, Downtown, and the North, South and West Ends. It’s the third of four phases the city is undertaking as it adds hundreds of new stations for the Blue Bikes program, run in partnership with the rideshare company Lyft.

Today Beacon Hill is a relatively underserved part of the network, boasting only two or three stations compared to the dozens scattered around the financial district. Beacon Hill stands out as the only downtown neighborhood failing to meet the city’s goal of having every downtown resident within a 3-5 minute walk of a station, apart from some spots near the waterfront.

“Our goal is for stations to be within an easy walk from you. Today, nearly 90% of households are within a 10-minute walk of a bike share station,” wrote the Transportation Department. “You may hear us talk about the importance of ‘station density.’ Basically, we want to be sure bike share stations are not too far apart from each other. More nearby stations also mean more places to find a dock or a bike if one rack is out or full.”

Part of the disparity between neighborhoods may lie in their different uses. While Beacon Hill is only beaten out in terms of population density by Chinatown and parts of the North End, job density is dramatically more concentrated in the financial district and Chinatown.

That may also explain why Beacon Hill still isn’t a focus in the latest expansion. Of the thirty stations being added, only two lie within Beacon Hill, one at the corner of Charles Street and Revere and the other at Cambridge and Bowdoin.

Neither is particularly close to the most underserved area next to the Common, and it’s possible some spots may still remain more than five minutes from a station on foot.

The Beacon Hill streets themselves certainly don’t make it easy to find spots for a large, automated bike rack. Planners look for open spaces with many sightlines and extra sidewalk room for pedestrians, which eliminates many of Beacon Hill’s streets from consideration.

The least served parts of Beacon Hill are also not demand hotspots in the city’s estimation. The largest missed opportunities on their map are both along Cambridge Street, and both will be well served by the new Beacon Hill stations.

The bulk of the new stations downtown will go around Tufts Medical Center, Downtown Crossing, South Station and the southeast reaches of the West End.

New stations throughout the South End, Seaport, East Boston and Charlestown will be coming later this year. Planning for the last phase, focusing on neighborhoods further afield, won’t begin until 2025.

Though the last open house of the third phase took place on August 14, residents still hoping to get a word in on the downtown expansion can submit written comment and get more details on the city’s plans at boston.gov/bike-share-expansion.
