Sierra Madre New Construction With Water Planned First
New Construction in Sierra Madre: roof, surface and wall water routed to approved outlets, waterproofing below grade, city review and ember-ready details.
Water decides as much of a new Sierra Madre house as the floor plan does. Roof runoff, surface flow across the lot and groundwater behind any retaining wall each need a route to an approved outlet, drawn on the grading plan before framing. Sierra Madre has parcels on the fire hazard maps, so gutters, vents and roof edges are also chosen to keep embers out of the house.
Walls, drains and the slab
Where the lot slopes, a retaining wall behind the house holds the cut, and that wall gets a perforated drain at its footing, gravel backfill and waterproofing on the soil side. Ground moisture is kept out of the floor by crushed rock under the slab and a vapor retarder laid on it. Downspouts tie into solid pipe that carries roof water away from the foundation, and the finished ground is sloped so surface water runs off from the house. The soils engineer's report sets how far water must be carried before it is released.
Review by the city
Sierra Madre is an incorporated city, so its building department reviews the plans and the grading. Expect questions on drainage, on the foundation design against the soils report and, on a fire-mapped parcel, on the ember-resistance details for vents, roofing and siding. The state energy forms are checked as well. Retaining walls above a set height may need their own engineering and permit. We keep the review comments, our answers and the revised sheets together, so the approved set on site matches what the inspector expects at each visit.

New Construction in Sierra Madre: questions
Before the design is final, a surveyor maps the property lines and grades, a geotechnical engineer reports on the soil, and a civil engineer turns both into a plan for grading and drainage. If the lot slopes or sits near a drainage course, the geotechnical engineer may add a slope study. A parcel on the fire map may also need a fuel modification plan.
The approach sets the method. Forms beyond a truck's reach need a pump, heavy beams may need a crane, and a tight frontage can mean smaller loads and more trips. Where drain pipe has to run a long way to reach the street, that trenching sits on the same site line.
Yes. Send the architectural and structural sheets with the soils report, and the quote comes back split between site work, foundation and the house trades. A wall drain with no outlet shown, or roof water with no route, is listed as a question, since the answer can move the site cost.
