What is Floodplain Mapping?

Floodplain mapping identifies areas at risk of flooding based on hydrological studies and historical data. Maps guide development decisions, insurance requirements, and emergency planning.

Why Floodplain Mapping Matters in Real Estate

Floodplain mapping matters in real estate because it impacts land use, property value, and financing. Properties in floodplains may face building restrictions, higher insurance costs, and reduced marketability.

Example of Floodplain Mapping in Action

A developer consults municipal floodplain maps before planning a new subdivision to ensure compliance with building restrictions and avoid high-risk areas.

Key Takeaways

  • Identifies areas at risk of flooding.
  • Used in planning, insurance, and emergency management.
  • Affects property value and development potential.
  • May restrict construction in high-risk zones.
  • Increasingly important with climate change impacts.

7,500-Unit Master Plan On Former Military Air Field Breaks Ground In Prince Edward County

Prince Edward County — land of wineries, farms, and quaint storefronts — will soon be home to one of Ontario’s largest residential developments: a 7,500-unit master-planned community located on the site of a WWII military air field. Dubbed Base31, the lands have undergone significant transformation since being purchased by developers in late 2021. But last Friday marked the biggest milestone yet, with the groundbreaking of the development’s first residential projects.

The 750-acre site is located two kilometres south of the rural town of Picton, roughly 160 km east of Toronto and just 14 minutes from the sloping dunes of Sandbanks Provincial Park. It’s a quiet place, but one with a rich history the developers are tapping into.

Small-scale infill projects have gone from a barely noticeable share of Toronto’s housing starts to a more meaningful one in just two years, according to a new analysis from Canada Mortgage and Housing Corporation (CMHC). Last year, smaller infill projects — accessory dwelling units and buildings with two to eight units — accounted for 6.45% of the city’s total housing starts, and while that figure may seem slight, it’s up more than tenfold from 0.62% in 2023.

The growth of small-scale infill has been particularly pronounced in a handful of other Canadian cities. In Vancouver, these projects accounted for 18.07% of total housing starts in 2025, up from 13.22% in 2023. Edmonton saw an even larger increase, from 9.95% to 23.28% over that two-year course. CMHC describes Calgary as also having ”strong growth in small-scale infill.”

Canadian renters with aspirations to move are facing much more than a logistical hassle, according to a new report on housing affordability from Statistics Canada (StatCan). The research, which draws from the fourth cycle of the Canadian Housing Survey, shows that moving in today’s private rental market comes at a premium, costing tenants hundreds of dollars more per month.

According to StatCan, the average monthly rent for tenants who had moved in the two years leading up to 2024 was $1,740, compared to $1,290 for sitting tenants who occupied their residence for at least two years. That translates to an average of $450 more per month — or $5,400 more per year — for renters who have recently moved.
