Why Kensington Landscape Design Costs Track Differently Than Coronado
A Kensington landscape design project costs less to irrigate for salt but more to plan for heat, since the mesa runs 8 to 10 degrees hotter than the coast on an August afternoon. Cost tracks plant selection, hardscape square footage, and how much shade the property's mature trees throw, not the neighborhood's reputation.

Kensington sits far enough inland that the salt corrosion we design around on Coronado's bayfront mostly disappears. Brass and stainless irrigation heads aren't the requirement here that they are on Ocean Blvd.
But the mesa runs hot. On an August afternoon it can run 8 to 10 degrees warmer than a yard two miles west on the island, with no bay breeze pulling heat off the beds by four o'clock. A plant that holds up fine in full afternoon sun on 1st St will cook on a west-facing Kensington lot, because the exposure looks the same on paper and behaves nothing alike.
What we check before pricing a Kensington yard
Samuel Fortes walks every property before drawing a plan. On the blocks north of Adams Avenue, that walk usually turns up the same three things: a Spanish Revival home with a defined entry path, at least one mature jacaranda or pepper tree throwing more shade than the owner accounts for, and a front yard sized for low massing rather than a big lawn.
We measure actual sun hours on the bed before pricing anything. A drought-tolerant palette dropped into a shaded courtyard just sulks, no matter how well it did on the plant tag.
Take the job we finished this spring on Marlborough Drive, three blocks north of Adams Avenue: 1,100 square feet of front and side yard, roughly half hardscape and half planting. We tore out a dead lawn, laid 340 square feet of decomposed granite path, and reset the drip irrigation to 25 PSI with 2 GPM emitters spaced for the new olive and rosemary bed. Total came in at $19,400, which sits in the middle of what a Kensington project like this typically runs -- our quotes there range $14,000 to $26,000 depending on how much of the yard stays lawn versus hardscape.
How does a Kensington landscape design compare to a Coronado one?
| Coronado Bayfront | Kensington Mesa | |
|---|---|---|
| Salt exposure | High -- brass and stainless irrigation required | Low -- standard hardware holds up |
| Afternoon heat | Moderated by bay breeze | 8-10 degrees hotter, no breeze relief |
| Common palette | Pittosporum, agave (bay side only) | Olive, rosemary, agave, low hedging |
| Hardscape | Pavers, retaining walls near bay | Decomposed granite paths, low masonry |
The plant list overlaps more than people expect. Agave that rots on Coronado's ocean side does fine on a dry Kensington slope. Olive and rosemary hold up in both, but they read differently against a Spanish Revival facade than against a beach cottage.
What actually drives the price on a Kensington project
Three things move the number more than square footage does: how much of the yard is hardscape versus planting, how many mature trees need working around, and how far material has to travel from the street to the back of the lot.
Decomposed granite paths cost less to install than poured concrete and fit the Spanish Revival character better. On the Marlborough Drive job that path ran about $9 a square foot installed, versus the $16 a square foot we'd have charged for poured concrete. But granite needs edge restraint and periodic topping up, or it migrates onto the lawn within a season.
We phase the work so the street-facing bed goes in first, the same way we sequence a Coronado job. On a Kensington lot that usually means the low hedge and entry planting get set before the backyard work starts, since that's the part the street sees every day.
Does Kensington need a different irrigation plan than the coast?
Yes. A Kensington irrigation plan doesn't need the salt-rated brass and stainless heads we require on Coronado's bayfront, but it does need more run time and shade-aware zoning, since the mesa's heat and lack of ocean breeze dry beds out faster than an identical layout on the island.
We zone irrigation by sun exposure, not just by plant type. A bed under a mature pepper tree needs a fraction of the water a west-facing entry bed needs in August, and running them on the same valve wastes water on one side and starves the other. On the Marlborough Drive job we split what would have been one 25 PSI zone into two, so the shaded bed runs half the minutes the entry bed does.
