Beverly Hills

Q: How is Beverly Hills different from LA County for construction permits?

Beverly Hills has its own Building and Safety department separate from LA County. Projects in Beverly Hills require city permits in addition to any county requirements. The city also has specific drainage requirements, including the requirement to drain to the street curb rather than to alleys.

Q: Why can Beverly Hills properties only drain to the street and not alleys?

Beverly Hills city code requires stormwater to discharge to the street curb. This is different from some other LA cities where alley drainage is permitted. Depending on your site grades, this means either a gravity system that sheet flows to the street, or a sump pump system that collects stormwater and pumps it up to the curb.

Q: What engineering does a Beverly Hills hillside property need?

Beverly Hills hillside properties require grading plans, drainage plans, and erosion control plans. The drainage plan must account for the street-only discharge requirement. Properties with significant slope changes may need excavation plans. We handle the full scope of civil engineering for hillside projects.

Civil Engineering and Grading Plans in Beverly Hills

Beverly Hills has its own Building and Safety department with requirements that differ from surrounding LA County areas. One unique aspect: you cannot drain to alleys. Stormwater must go to the street curb, either by gravity or via pump system.

We have completed projects throughout Beverly Hills, from hillside grading plans to drainage for new home construction. We understand how Beverly Hills Building and Safety reviews projects and what documentation they require.

Beverly Hills Building and Safety

Unlike LA County, Beverly Hills has its own Building and Safety department. Projects require city permits separate from county. We know how to put together plans that meet Beverly Hills standards and move through the approval process efficiently.

Drainage to the Street (No Alley Drainage)

A key difference in Beverly Hills: you cannot drain to alleys. All stormwater must discharge to the street curb. Depending on your site grades, this means either a gravity pipe system that sheet flows to the street, or collecting roughly half the site stormwater in a sump pump and pumping to the curb. We design both approaches based on what works for your specific site.

Hillside and Flat Lot Experience

Beverly Hills has distinct terrain. The hillside properties above Sunset and Mulholland require careful grading and drainage engineering. The flat lots have their own challenges with stormwater management and meeting the city requirement to drain to the street. We work on both.
