Civil Engineering Services
A grading plan shows how ground elevations will change around a building, driveway, or other improvement. A drainage plan shows where rain and snowmelt will flow. Calicore designs both together for permitting and construction.
Service overview
Calicore prepares site-specific grading documents for residential and light-development projects, including pad elevations, slopes, drainage paths, earthwork concepts, erosion-control details, and coordination with the building and septic layout.
Local terrain, snowmelt, desert runoff, access, existing improvements, and county submittal requirements are addressed early so the plan works as one site—not disconnected disciplines.
Step by step
The exact scope is matched to the project, but a typical assignment follows these steps.
We identify the reviewing jurisdiction, whether a separate grading permit is expected, and which calculations or supporting reports may be required.
Suitable topographic and parcel information is assembled before proposed elevations are designed.
The building pad, finished floor, driveway, slopes, drainage paths, utilities, septic area, and retaining features are considered together.
We issue the grading and drainage documents, support review, and update the civil design when agency comments or project changes require it.
Review criteria
A grading plan must show how the site will be changed and where runoff will go without creating an unaddressed impact on roads, structures, neighboring property, or wastewater areas.
Requirements vary by city, county, special district, parcel, and project type. Calicore confirms the current requirements with the reviewing agency before finalizing the scope.
What you receive
Common project needs
Frequently asked
Usually. The design needs reliable existing elevations and site features. Calicore can collect design-level topographic data or coordinate a licensed land survey when boundary work is required.
Yes. Coordinating the building pad, drainage, access, test locations, and OWTS area early is often the most efficient approach.
