Commercial Construction in North Hollywood
North Hollywood commercial buildings planned around storm water: soils tested for infiltration, planters or dry wells sized, and the shell fitted to the lot.
"How much of the lot can we pave before storm water becomes a permit problem?" It is a fair question for the first walk of a North Hollywood commercial site, and the answer shapes the whole site plan. In the City of Los Angeles, new paving and roof area can bring low impact development rules, which ask that rain be captured, soaked into the ground or treated on the property. We read the soils and the lot grade before choosing a method.
Planters, dry wells and the soils report
Which storm water method works depends on how fast the ground drains. Where percolation tests show the soil takes water well, a dry well or an infiltration trench can hold roof runoff. Clay or old fill that drains slowly pushes the design toward a planter with a lined bottom and an overflow to the street. On a lot that slopes toward a neighbor, infiltration near the property line is avoided, since water moving downhill can reach the next foundation. Sizing belongs to the civil engineer, whose sheet sets what gets built.
Fitting the shell to the lot
Once the storm water layout is set, the building footprint and the parking follow it. Footings go to the depth the geotechnical report calls for, and any retaining wall gets a perforated drain or weep holes behind it. Utilities are trenched before the slab is poured, with sleeves left for later tenant work. Our quote shows grading, storm water, foundation and shell as separate divisions, so the cost of each choice on the site plan stays visible when the layout shifts during design.

Commercial Construction in North Hollywood: questions
Three documents come before design: a survey showing boundaries and grades, a geotechnical report with percolation results, and a utility search for sewer, water and power connection points. Footing design and storm water planning both depend on them. If any one is missing, our quote lists it as an open item.
We fence a storage yard on the part of the lot built last and plan truck access so deliveries never wait in a travel lane. Concrete pours are booked with the pump placed on the property where it fits. Materials arrive in the order each trade needs them. Work that blocks a sidewalk or lane is permitted through the city first.
It is. Each division has its own line and subtotal: site prep and grading, storm water, concrete, structure, envelope, roofing, mechanical, electrical, plumbing and finishes. Engineering, permit fees and testing stay separate from construction. That format lets a lender or partner compare it line by line with their own budget.
