Retaining Walls in Coldstream, BC
From Kalamalka Lake up through Middleton Mountain, Coldstream’s old orchard benches and steep lakeview lots make grade change the defining fact of most properties — and a well-built retaining wall the thing that turns a slope into usable, sellable outdoor space.

Retaining walls generally range from $8,000 to more than $100,000, depending on wall height, length, material, drainage, access and engineering requirements.
Wall length × average wall height = wall-face square footage
This calculator provides an early budget range only and is not a formal quote. Final pricing depends on site access, existing conditions, excavation, grading, drainage, material selections, engineering, permits, electrical and plumbing requirements, and the final approved design. Pricing is shown in Canadian dollars and excludes GST unless otherwise stated. A site consultation is required to provide an accurate proposal.
Coldstream was built on terraces
Coldstream grew up as orchard country, and orchards were planted on benched, terraced hillsides long before the houses arrived. That history is still written into the lot lines today: many Coldstream properties, especially the ones climbing toward Middleton Mountain or dropping toward Kalamalka Lake’s east side, carry grade changes of several feet within a single backyard. Where an older orchard terrace has been left to erode or was never properly walled in the first place, that slope becomes a liability — runoff cutting channels through the lawn, tree roots undermined, soil migrating downhill onto a neighbour’s fence line. A retaining wall built to hold that grade does more than tidy up a slope; it recovers flat, usable ground on a lot that otherwise gives most of its square footage to hillside. It also matters for compliance: the District of Coldstream, like most Okanagan municipalities, requires engineering review on walls above a certain height and setback from property lines, and lakeside lots often carry additional environmental development permit conditions tied to Kalamalka Lake’s watershed. Getting the engineering, drainage, and permitting right the first time is the difference between a wall that lasts decades and one that needs to be torn out and redone.
Serving Coldstream Since 2018
Featured ProjectNatural Stone Terrace, Coldstream
On a sloped orchard-era lot, we built a series of natural stone retaining walls to reclaim level terraces for living and garden space, replacing a failing hillside with terracing that reads as if it had always been there. See the full project.

Trusted By Okanagan Homeowners
“Kalagan did an outstanding job on our major landscaping project that included two sets of stone steps, a large water feature, paving stone patio, several plant beds, irrigation system and lighting effects. Taylor brought a wealth of knowledge and ideas to the design process and was easy to work with. Communication was strong throughout the project and we heartily recommend Kalagan for your landscaping project.”
“Kalagan Outdoor Design completely gutted our backyard, then installed irrigation, new lawn, trees, shrubs, rock bordered planting areas and a new stone patio. We are absolutely delighted with the result. It far exceeded our expectations which were quite ambitious from the start. The entire team was a pleasure to work with — professional, courteous, creative and hard working.”
Common Questions About Retaining Walls in Coldstream
Can you rebuild an old, failing retaining wall?
Yes. We regularly rebuild and refurbish existing walls that are leaning, bulging, or breaking down, replacing them with a properly engineered wall built to last.
Do retaining walls need a permit?
It depends on the wall’s height, location, and your municipality. Taller walls, waterfront walls, and walls near property lines are more likely to require engineering and permitting. We handle the regulatory side as part of the project.
Why do so many Coldstream properties need retaining wall work?
Coldstream grew up as orchard country, and orchards were planted on benched, terraced hillsides long before the houses arrived — that history is still written into today’s lot lines, with many properties toward Middleton Mountain or Kalamalka Lake’s east side carrying several feet of grade change within a single backyard.
What happens when an old orchard terrace was never properly walled?
Where an older orchard terrace has eroded or was never properly walled in the first place, that slope becomes a real stability concern — we assess these older terraces and engineer a proper retaining solution rather than patching the existing grade.
