An urban layout that changes the job
In Old Hull and the streets around promenade du Portage, many houses are semi-detached or separated by a one-metre alley. Gutters there are often narrower than on newer builds, and downspouts end straight on the sidewalk or in a very small back yard. A blockage shows up fast: water sheets down the wall instead of draining.
Mature street trees, maples and lindens along the curb, drop directly onto the front roof, while back yards mostly collect fine debris and moss.
