Yavapai County Grading & Drainage Plans for Hillside Homes
Civil engineering for builders and homeowners who need a practical Grading & Drainage plan for a custom home, hillside lot, or difficult residential site in Yavapai County, Arizona.
Crowther Engineering, LLC prepares grading and drainage plans for custom homes, hillside lots, infill parcels, and difficult residential sites throughout Yavapai County, Arizona.
Most of the time, we are brought in after the big decisions are already made. The house is placed. The finished floor elevation may already be selected. The driveway location is shown. The architect has a plan. The builder is trying to move toward permit. Now the project needs a grading and drainage plan that works with the site.
That is where we help.
We work through the civil constraints — driveway grades, site drainage, cut/fill, swales, retaining wall coordination, utility conflicts, neighbor runoff, and jurisdiction requirements — and prepare construction-ready civil plans for the contracted civil scope.
Common Yavapai County G&D Issues We Help Solve
Custom home and hillside lots in Yavapai County often involve tight site constraints. A grading and drainage plan needs to do more than show arrows on a sheet. It needs to make the lot work.Common issues include:
Steep driveway grades and garage tie-in constraints
Finished floor elevations that are difficult to match to existing ground
Drainage crossing the proposed home, driveway, or outdoor living areas
Neighbor runoff and off-site drainage concerns
Excessive cut/fill or difficult site balance
Need for swales, ditches, culverts, or other drainage conveyance
Retaining wall coordination and grading impacts
Utility conflicts with drainage or driveway grading
Jurisdiction comments related to grading, drainage, or site access
Why Crowther Engineering
Crowther Engineering, LLC’s civil work is led by a licensed professional engineer. You work directly with a PE who understands both the lot-level details that affect a single home and the broader site constraints that can affect grading, drainage, access, and utilities.

Crowther Engineering, LLC is licensed in Arizona, Utah, Nevada, and Texas, and provides civil/site support for residential projects throughout Yavapai County and Northern Arizona.
Built Around the Site You Already Have
Not every project starts with a blank sheet.
If the home layout, FFE, driveway, or wall concept is already set, our job is to work within those constraints and identify the practical grading and drainage path forward.
Sometimes that means minor grading adjustments. Sometimes it means revisiting driveway grades, swale locations, pad elevations, culverts, retaining wall coordination, or how drainage leaves the site.
The goal is straightforward: prepare a G&D plan that can move through review, drain correctly, and be used by the builder in the field.
