TRCA Regulation Mapping: How To Build A House On A Regulated Lot

Building a Home on a TRCA regulated Lot

What would be the perfect lot to build your home or cottage on? Would it have a ton of mature trees, and maybe even a ravine? Would the lot slope away from the street, creating a great opportunity for a walk-out basement? Are you able to envision your pool with a backdrop of a dense forest, creating both privacy and a beautiful vista? Chances are, you’ll need to understand how TRCA regulation mapping works and what steps to take when building a home on a TRCA regulated area. Let’s dive into what this means.

Understanding TRCA Regulated Areas And Mapping

If you’re searching for a property like this in Toronto or the GTA, there’s a strong likelihood that you’re going to become familiar with environmental regulating bodies such as the Toronto Region Conservation Authority (TRCA) or the Lake Region Simcoe Conservation Authority (LSRCA).  When embarking upon a new project, we always start with an online search or a call to the regulating body (TRCA, LSRCA, etc.) to determine if the property is within their regulated area, or if they have any interest in the property. This is especially useful if the client is evaluating the purchase of the property. If the property is regulated by the authority, the required approvals can add months to the design and permitting process and can limit the buildability of the lot. Here’s what steps you can take when building a home on a TRCA regulated area.

Step One: USE TRCA REGULATION MAPPING AND CONSULT EARLY ON

When dealing with the TRCA or LSRCA, we consult with them early on in the process to streamline the design process. By meeting on-site and understanding the limitations, opportunities, and requirements, we reduce the time wasted in design revisions.

Step Two: Do Your Research

Do your research and become familiar with the property and the surrounding environment. This will allow you to assess the project viability, and whether you’re able to accommodate the requirements. Be prepared to hire consultants such as a surveyor, geotechnical engineer and arborist so that you’re equipped with all the information you need to best understand the lot.

Step Three: Listen and Understand TRCA Requirements

It’s important to understand the mandate of the regulating body. Their regulations are rooted in a goal to protect natural environments (valleys, streams, wetlands, etc.) In our past experiences, we have been able to work closely with them to satisfy their requirements without compromising the project goals. If the regulations limit the ability to build on the lot, they have been accommodating and supportive in providing us with justifiable reasons for asking for relief from by-laws at the Committee of Adjustment.

Step Four: Present your Proposal to TRCA

Discuss openly what you want to do, where you want to build, and what precautionary steps that should be taken. Understand clearly what you need to do for them to support your development or design.

FAQs

What is TRCA regulation mapping?

TRCA regulation mapping is a tool used by the Toronto Region Conservation Authority to illustrate areas that may be regulated under applicable legislation. These areas can include features such as valleys, ravines, wetlands, floodplains, and other natural or hazardous lands. The mapping is intended as a general guide only and does not replace a formal review by TRCA staff.

How do I find out if my property is in a TRCA regulated area?

You can start by reviewing the online TRCA regulation mapping or other publicly available tools to see whether your property may fall within a potential regulated area. These resources are conceptual and may not reflect site-specific conditions. For confirmation, property owners should contact TRCA directly and, where appropriate, consult with qualified professionals such as an architect, planner, or engineer.

Do I need an architect if my lot is in a TRCA regulated area?

Requirements can vary depending on the municipality, the scope of work, and TRCA’s review process. In many cases, it may be helpful to work with an architect or other qualified professionals who have experience with TRCA reviews, regulation mapping, and related approvals. Property owners should confirm specific requirements with their local municipality and TRCA.

Building On TRCA Regulated Land: Challenges And Rewards

The process can vary with each jurisdiction, but ultimately working closely together from the start is necessary for a successful project. Building on a property with interesting natural features, such as woodlots, ravines, and watercourses, can be challenging. In the end, however, the reward presents itself in the form of a truly unique and environmentally sensitive building.
