North Canal Historic District (Boundary Increase)
Why it's listed
Lawrence's North Canal district is a mile-long, 60-acre tract of mills, bridges, streets and hydraulic works laid out beginning in 1845 by the Boston-based Essex Company. Water from the Great Stone Dam, completed in 1848, fed a 5,330-foot canal that powered large brick textile factories for a planned city. The surviving buildings show how industrial design changed over time, from early granite rubble mills to flat-roofed brick mills and reinforced concrete, with changes driven by steam power, fire insurance requirements and ventilation systems. Thirteen bridges cross the canal and river, including the 1887 Union (Duck) Bridge and the 1918 Central Bridge. This 2009 amendment extends the period of significance to 1959 and adds the Morehouse Bakery Building, built in 1907 as a wholesale bakery that ran until 1976. It employed many workers after the textile strikes and supplied bread to the Merrimack Valley. The district is recognized for its industrial history and architecture.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
