Rainwater can pool on this lot in a heavy storm
Free preview- What the record says
- The City’s map of runoff basins (2021) shows low spots on about 225 m² of the lot (68 %) where more than 300 mm of water can collect.
- What it means
- In an intense storm, when the sewers are full, rainwater gathers in these low spots before it can drain. Water standing against a house is a common way into basements: window wells, doors, cracks, or a driveway that slopes down to a garage. The map is a model made from 2015 elevation data, not a record of past floods.
- What to do
- Look at where the low spots are (yard, lane, driveway), ask the seller about water in the basement and insurance claims, have the inspector check the grading, the backwater valve and the sump pump, and ask your insurer about overland water and sewer backup cover.
