At OAL Engineering, we provide expert Stormwater Management Design services tailored to meet the needs of residential, commercial, and municipal developments. Effective stormwater management is essential for controlling runoff, preventing flooding, protecting infrastructure, and meeting regulatory requirements. Every project we undertake is backed by a thorough analysis of the site’s physical conditions, including grading, soil characteristics, and surrounding drainage systems. Our goal is to design systems that function reliably, integrate seamlessly with your overall site plan, and comply fully with municipal and environmental standards.

Our approach begins with hydrologic and hydraulic modeling to understand how water will behave both before and after development. We design practical, code-compliant systems that manage runoff through a combination of storage, conveyance, infiltration, and treatment. Common design components may include:

• Detention and retention systems such as storm ponds, underground tanks, or infiltration trenches
• Storm sewer networks and drainage channels that safely convey runoff
• Erosion and sediment control measures to protect surrounding areas during construction

We also incorporate Low Impact Development (LID) solutions where appropriate, including:

• Permeable pavements
• Bioswales and rain gardens
• Green roofs and infiltration systems

All designs are prepared with attention to regulatory detail, ensuring full compliance with municipal standards, provincial guidelines, and conservation authority requirements. In addition to technical design, we provide all necessary documentation for approvals, including stormwater management reports, grading plans, erosion control plans, and Functional Servicing Reports (FSRs).

Whether you're developing a new subdivision, upgrading an infill lot, or retrofitting an existing site, OAL Engineering delivers practical, efficient, and environmentally responsible stormwater solutions. Our clients trust us to streamline the approval process and deliver high-quality results that protect both property and the surrounding environment.
