What does landscape construction cost above Sunset Cliffs?
Landscape construction on a sloped lot below Sunset Cliffs is priced by drainage and retaining wall work first, not planting. On a recent Sunset Cliffs Blvd job, wall and drain work ran about $28,000 before any planting went in. Wall height and drain line length drive the number more than square footage does.

We rebuilt that yard off Sunset Cliffs Blvd after a February storm washed the lower bed into the neighbor's side yard. The plants weren't the problem. The grade was, and the fix ran three weeks longer than a flat-lot job of the same size.
Water moves before anything green goes in on these lots. We stake how runoff leaves the property first, then set drain lines and wall heights, then draw the beds around that.
Why drainage runs the budget on a Sunset Cliffs lot
Drain lines get pitched a quarter inch per foot of fall. Drain rock sits over four-inch perforated pipe behind any retaining wall on these slopes, because a wall that traps water instead of shedding it fails within a season or two, not decades.
Salt wind off the water reaches these lots the way it reaches the Coronado bayfront. We run brass and stainless irrigation heads on pressure-rated PVC out here for the same reason. Plated hardware pits out fast this close to the ocean.
How much does a retaining wall cost below Sunset Cliffs?
Once retained height passes roughly four feet, the wall needs engineering and a different scope than a standard C-27 planting bid covers. That threshold is the single biggest cost swing on a sloped Point Loma or Sunset Cliffs lot. Segmental block walls under four feet typically run $45 to $65 per square face foot installed, drainage included. Push past four feet into engineered poured concrete and that climbs to $90 to $140 per square face foot once you add the stamped plan, deeper footing, and inspection fees.
| Wall Type | Typical Height Before Engineering | Drainage Behind Wall |
|---|---|---|
| Segmental block | Up to about 4 ft | Drain rock over perforated pipe |
| Poured concrete | Engineered above 4 ft | Weep holes plus drain rock |
| Terraced low walls | Under 2 ft per tier | Graded fall between tiers |
We terrace planting where the slope allows it, so roots hold soil between wall tiers instead of asking one wall to do all the work.
Do you need an engineer for a retaining wall in Point Loma?
Most residential retaining walls under about four feet of retained height fall under a standard C-27 landscape contractor scope. Past that height, or when a footing carries a structure above it, the job needs a stamped engineered plan before we price the build.
We say so before any deposit changes hands. A wall that needs an engineer costs more up front and holds up longer, and pretending otherwise is how a bed above Sunset Cliffs ends up in the yard below it.
How long does construction take on a sloped Sunset Cliffs lot?
Access decides the calendar out here more than it does on a flat Coronado lot. Material that can't reach the back by machine gets staged and moved by hand, and that stretches the schedule. Demo and haul-out go first. Drainage and wall work come next and have to cure. Planting goes in last, after the structural work is settled, so nothing green gets buried under base rock or washed out before it roots.
