Commercial Construction in Sherman Oaks
Commercial construction in Sherman Oaks with roof, paving and below-grade drainage planned first and priced on separate lines inside the written quote.
Follow one raindrop off the roof of a Sherman Oaks commercial building: scupper, downspout, paving, footing line, then the street or a storm connection. We draw that path before the floor plan is settled. On a lot that steps down, runoff gathers speed and any retaining wall needs drains behind it. LADBS reviews the drainage layout as part of the City of Los Angeles permit.
Roof and paving runoff
Roofs drain to downspouts tied into underground pipe, and none discharge across a walkway. Paving is sloped away from the building, and a trench drain sits at any door where the floor lands close to grade. Storefront thresholds and loading doors get sloped aprons so water cannot work under the sill, and the slope is checked with a level before paving is poured. Where site runoff has to be held or filtered before it leaves the parcel, the civil engineer sizes the system and we build it to that plan.
Water control below grade
Footings and walls below grade are protected with membrane waterproofing and a drainage board, with a perforated pipe in clean rock at the base that runs to daylight or a sump. If the soils report notes shallow groundwater, the design may add a sump pump with a backup. These items are priced on a line apart from foundation and structure, so you can hold them against the engineer's recommendation and see what the protection adds to the job. The same line also records the pump size and the discharge point shown on the plans.

Commercial Construction in Sherman Oaks: questions
A survey and a geotechnical report lead, followed by a drainage or hydrology study showing where site runoff must go. Because the permit comes from LADBS, the grading sheet and the stormwater plan should agree with each other. We read them together and mark any conflicts for your civil engineer before we price.
We keep the work area graded so rainfall never pools around open footings, lay plywood or gravel paths for trucks, and store materials off the ground under cover. On a tight parcel, concrete deliveries are timed so the pump and mixers do not block a neighbor's driveway.
Yes. Waterproofing, drainage and site stormwater work each show as their own line within the divisions, which makes them simple to compare with the engineer's design. Permit fees and special inspections sit apart from the build, so a revision to the drainage plan shows exactly where it lands.
