Site work on this lot

No surprises. Here’s why.

Our Formal Property Analysis found all of this before they signed.

Step 1 of 2

Found before we started

Our architect and engineers checked this lot before we designed anything. Finding these early is how we avoid surprises during the build.

Backfilling the utility trench, Jul 16, 2026

Longer utility runs

What we found during the FPA: Sewer, water and power lines had to run farther than usual.
How finding it early helped: We mapped the route and checked the sewer’s slope over that distance, then sized the pipe and wire for the length.
What it meant for this homeowner: The yard was dug once, and every line works the way it was planned.

Footings dug for the retaining foundation, Jul 17, 2026

Retaining foundation (3 feet high)

What we found during the FPA: The lot’s slope needed a retaining wall where the ADU sits.
How finding it early helped: Measuring the slope early let our engineer design the retaining wall together with the foundation, so the ground and the home were planned as one.
What it meant for this homeowner: Level ground under the ADU, and a yard that holds its shape.

The existing water meter, at the FPA site visit, Oct 17, 2025

Water meter upgrade

What we found during the FPA: The water meter was too small to serve two homes.
How finding it early helped: Sizing the new meter at the start let the water district swap it while the ADU was still being built.
What it meant for this homeowner: Good water pressure in both homes, with no wait on the water district at move-in.
