The residents of this districts were known to be invovled in smuggling or at least look away from their consorts smuggling stolen goods. That's why the sewers were easily accessible in this district, allowing people to go unnoticed if need be. Much of the city's trade was made in Riverside District, with the docks for river traffic being on its southermost point and therefore vessels from Corus or farther inland coming and going here. Thus there were quite a few warehouses in this district. The district's dock area ended by the breakwater, where the ground was too wet for buildings, only "a swampy mass of inlets".
