What AI Tools Actually Get Wrong About a Coronado Yard
AI design tools can generate a plant list from a photo in seconds, but they can't walk a Coronado lot, measure afternoon sun off the bay, or check a plan against an HOA hedge-height rule. Samuel Fortes still walks every property himself, because those details never show up in a satellite image.
A homeowner on 1st St showed us a rendering this spring from an AI design app. The plant list looked reasonable on paper. About a third of it was agave, and agave on that block's ocean-facing side rots within a season. The app had no way to know that, because it never saw the actual soil or the actual salt exposure.
That's the gap. Not creativity. Site knowledge.
Is AI Replacing Landscape Architects?
Not for the parts that matter on an island lot. A landscape architect's stamp exists for structural and public work, and no AI tool is signing off on an engineered retaining wall below Sunset Cliffs. For residential planting and hardscape, the harder question is whether the tool has ever seen your actual yard.
We've inherited jobs where a rendering got handed off and the plant choices were picked by someone, or something, that never measured the afternoon sun on that specific bed. Redoing a rejected design review submission is the most expensive mistake on the island, and no app carries that cost.
AI Design Tools vs. Walking the Lot
| Factor | AI Design Tool | Walking the Lot |
|---|---|---|
| Salt exposure | Not measured | Checked block by block |
| HOA hedge-height rules | Not checked | Drawn to the board's plant palette first |
| Side yard access | Not accounted for | Measured before pricing (some Coronado side yards run under 36 inches) |
| Irrigation corrosion | Not addressed | Brass and stainless heads specified for salt air |
| Cost accuracy | Generic estimate | Priced against the actual hardscape and plant count |
Can ChatGPT Do Landscape Design?
ChatGPT and similar tools can describe plant species, suggest layouts, and explain design terms, but they can't see your yard's grade, sun exposure, or soil, and they don't know your HOA's hedge rules. Drainage and retaining wall planning have to come before any planting decision, and that's a site visit, not a prompt.
We get asked about this more since AI tools became easy to try for free. Our answer stays the same. Use them to get plant names and ideas. Don't use them to finalize a plan for a lot with real drainage problems or a design review board.
What We Still Do By Hand
Sam walks the lot. He draws the plan by hand. He plants it. He comes back to prune it. That's the whole process, and it hasn't changed since we started working Coronado and Point Loma over a decade ago.
On the tight lots off B Ave, C Ave, and J Ave, mature trees and period-correct hedging set rules that only show up in person. On the bayfront blocks along Ocean Blvd, the afternoon sun off the water decides the plant palette before style enters the conversation. None of that is in a stock photo.
If you want to see what a hand-drawn plan turns into, our Coronado portfolio has finished beds from the properties we've planted, and our landscape design page walks through how we price a full front and back.
