Grading + earthwork
Cut and fill strategy, pad elevations, slope stability coordination, haul quantities and grading permit exhibits.
Engineering · Site + Utilities
The ground, the water, and the utilities decide what the building can be.
Civil engineering and utility coordination for hillside, coastal and infill sites across Los Angeles and Ventura County, from grading and drainage through service connections.
The idea
Most projects are won or lost below the finish floor.
Grading, drainage, retaining, septic or sewer, water service, power, and fire access are not details resolved after the design. On a hillside or coastal site they set the buildable envelope, the pad elevation, the driveway slope, and often the entire massing.
Apel Design coordinates civil engineering alongside the architecture from the first site study, so the drawings that reach plan check already reconcile the building with the ground it sits on and the services it needs.
Knowledge + experience
Site engineering carried through approval and construction.
Scope varies by site, jurisdiction and the licensed engineers of record on each project.
Drainage + hydrology
Storm water management, area drains, detention, dissipation, and low impact development requirements.
Retaining + slope
Retaining wall coordination with structural and geotechnical engineers on hillside and canyon sites.
Septic + sewer
Onsite wastewater feasibility, percolation coordination, leach field siting, or sewer connection and lateral routing.
Water + fire service
Domestic water sizing, fire flow requirements, hydrant locations, tanks and pump coordination where required.
Dry utilities
Power, gas, and communications routing, service points, transformer siting, and undergrounding coordination.
Driveways + access
Access grades, turnarounds, fire department access requirements and encroachment permitting.
Erosion + SWPPP
Erosion control planning and storm water pollution prevention documentation during construction.
The path
Survey, test, resolve, and connect.
Survey
Establish existing conditions, topography, boundaries, easements and existing service locations.
Test
Coordinate geotechnical and percolation testing so soil and wastewater assumptions are verified early.
Resolve
Reconcile grading, drainage, retaining and access with the architecture before the design is fixed.
Connect
Coordinate utility service, agency approvals and construction sequencing through to occupancy.
Questions
Useful clarity before the first conversation.
Does Apel Design perform civil engineering directly?
Civil engineering is performed by licensed civil engineers of record. Apel Design coordinates that work alongside the architecture and manages the interfaces between civil, structural, geotechnical and the building design.
Why does civil work matter so much on Malibu and hillside sites?
Slope, soil, drainage and the absence of sewer service in many areas mean the civil constraints often determine the pad location, the building footprint and the achievable square footage before the architecture begins.
When should civil engineering start?
At feasibility. Survey and preliminary grading and drainage strategy should inform the first massing studies, not follow them.
Can you coordinate septic where there is no sewer?
Yes. Onsite wastewater treatment feasibility, percolation testing coordination and leach field siting are routine parts of the work on unsewered sites.
One continuous thread
These do not happen in isolation.
Site engineering, approvals, documentation and building systems all constrain each other. On our projects they are resolved together, by one team, rather than handed between consultants.
