Irrigation Systems in Mission

The District of Mission requires a building permit for retaining walls over 1.2 metres and often requires engineered drawings for any wall on a slope steeper than 30 percent. Hillside development permit areas impose additional requirements on excavation, tree removal, and stormwater control. Trueform handles all permits and engineering.

Upland Mission (Cedar Valley, Silverdale, Mission Heights) sits on glacial till with frequent rock outcrops, often hitting bedrock within 18 to 36 inches. Hatzic, Ferndale, and the river flats are silty alluvium with a higher water table. Hatzic Prairie is organic lowland soil similar to Sumas Prairie in Abbotsford. This is why every Trueform irrigation Systems project in Mission starts with an onsite soil assessment before we finalize base depth, drainage, and reinforcement.

Mission receives 1,700 to 1,900 mm of rainfall annually, more than Abbotsford or Langley, because of its position at the base of the Coast Mountains and the orographic lift effect. Upland neighborhoods see more freeze thaw cycles than the Fraser lowlands. Stormwater events are common from October to February. Our irrigation Systems installations are designed for these specific conditions. Drainage capacity, freeze thaw movement, and seasonal load are all factored into the spec for every Mission project.

We complete irrigation Systems projects across all of Mission, including Cedar Valley, Silverdale, Hatzic, Ferndale, Mission Heights, College Heights, and also Cherry Ridge, West Heights, Mission City, Hatzic Prairie, Stave Falls. If your Mission address isn't on this list, we still serve it. Call (604) 217-8966 to confirm.

Assume every upland Mission project will hit rock. Budget for it in the quote, not as a surprise change order. Never skip the drainage plan in Mission, because runoff volumes are higher here than anywhere else we work. And in Hatzic Prairie, plan for slight settlement the same way we do on Abbotsford's Sumas Prairie.

Irrigation system costs in the Fraser Valley range from $3,000 to $8,000 for a typical residential property, depending on the number of zones, system complexity, and property size. A basic 4 zone system for a standard lot costs approximately $3,500 to $5,000. Larger properties with 8 or more zones, extensive drip systems, and smart controllers range from $6,000 to $12,000. Annual winterization and spring startup services are available. In Mission specifically, the cost driver to watch is the soil and access combination.

We give you a transparent itemized estimate after the onsite visit so there are no surprises once the irrigation Systems build starts.
