Ever wonder what happens to all that BC rain once it hits the pavement?
In the Lower Mainland, we know rain. But when we build new homes, commercial spaces, or roads, we replace natural soil (which absorbs water) with "impermeable" surfaces like roofs and asphalt. Without a plan, that water has nowhere to go but toward flood zones or local waterways.
What exactly is a Stormwater Management Plan (SWMP)? Essentially, it’s a professional blueprint designed by civil engineers to control the quantity and quality of runoff. It ensures that rainwater is collected, treated, and released back into the environment or the municipal system at a controlled, safe rate.
Why is it designed?
🚫 Flood Prevention: It protects your property (and your neighbors) from water pooling and structural damage.
🌱 Environmental Protection: It filters out pollutants like oil and sediment before they reach our local salmon-bearing streams.
⚖️ Municipal Compliance: Most cities require a certified SWMP to meet bylaws and secure building permits.
💰 Cost Savings: A proactive design prevents expensive erosion and drainage repairs down the road.
At Westridge Engineering & Consulting Ltd. we specialize in creating practical, cost-effective stormwater solutions that keep your projects compliant and on track. From site grading to complex detention systems, we’ve got you covered.
