Maps: Where the moving trucks will be in Boston as students invade

<?EM-dummyText [Drophead goes here] ?>

Roughly two-thirds of leases for the more than 165,000 apartments in Boston expire as August transitions to September, officials estimate. And that means the arrival of a herd of moving trucks.

So many trucks.

The city asks movers to apply for special permits to reserve a curbside spot outside their apartment if they're planning to use a moving truck.

City records show those permits spike dramatically each year on Aug. 31 and Sept. 1.

This year, 550 permits will be active citywide on Aug. 31 and another 907 on Sept. 1. Monday was the deadline to obtain a permit in time for Sept. 1.

Those figures don't account for movers who won't get a permit for their moving truck.

By comparison, on an average day in 2015, there were about 40 moving truck permits active, city data shows.

(Fun fact: The only two days when there were no active moving truck permits last year? Christmas and Thanksgiving.)

The chart below, based on 2015 data, shows just how dramatic the increase in trucks is on Aug. 31 and Sept. 1.

The two maps below show how certain neighborhoods, particularly those with large concentrations of college students living off campus, are flooded with moving trucks this time of year.

This first map shows a dot for each moving truck permit that will be active on Aug. 31 and on Sept. 1 this year. Hover over a dot to see which date the permit there is active for.

Below is an image of a heat map of the same data. The map was made using a tool on the city's online data website.

If you park your car in the city, you may want to check if anyone near you has received a special permit for a moving truck, or for another reason, that may force you to move your car. You can look up permits by street name here.

And if you plan to drive around certain parts of the city this week, in a moving truck or other vehicle, you'll want to take note of the temporary traffic and parking bans in the Allston, Brighton, Fenway, Mission Hill and Roxbury neighborhoods.
