Civil Engineering for Ground-Mounted Solar.
Grading, drainage, stormwater, access roads, and permitting for community-scale and utility-scale ground-mounted solar projects. Senior PE on every project across Minnesota and Colorado.
The civil scope under a solar array.
Solar civil engineering is the civil scope for a ground-mounted solar project: grading, drainage, stormwater management, access road design, and permitting coordination for the site that the solar arrays will sit on. It's distinct from electrical engineering or solar racking design, which are typically handled by other specialists.
The civil engineer's job on a solar project is to make the site buildable, drainable, and permittable. That means grading the site within the constraints of the panel rows, designing drainage that works between and around the array, sizing access roads for delivery and O&M traffic, integrating stormwater BMPs, and shepherding the project through state and local approvals.
Solar civil engineering looks superficially similar to other land development work, but the constraints are different. Successful solar projects come from civil engineers who understand the array geometry, the developer's economics, and the agency landscape.

Civil scope on a solar project.
Site Feasibility & Layout
Topographic constraints, soils review, drainage analysis, environmental and wetland mapping, and coordination with the racking layout to optimize developable acreage.
Grading Within Array Constraints
Minimal-disturbance grading strategies that keep the panel-row geometry intact while addressing site drainage, slope stability, and access requirements.
Drainage & Stormwater
Drainage design between rows of panels, stormwater BMPs that coexist with the array, and SWPPP development for state-level construction stormwater compliance.
Access Road Design
Internal access roads sized for equipment delivery and O&M traffic, plus coordination with state DOT or county for site-entry approval.
Permitting & Entitlements
Conditional use permits, zoning amendments where required, MPCA / CDPHE construction stormwater permitting, and county or state utility commission coordination.
Decommissioning Plans
Many solar jurisdictions now require decommissioning plans as part of project approval. We prepare end-of-life decommissioning plans that meet local requirements.
Solar civil engineering questions, answered.
What is solar civil engineering?
Solar civil engineering is the civil scope for a ground-mounted solar project: grading, drainage, stormwater management, access road design, and permitting coordination for the site that the solar arrays will sit on. It's distinct from electrical engineering or solar racking design, which are typically handled by other specialists.
Do you handle community-scale solar?
Yes. Community-scale solar (typically 1 MW to 5 MW) requires the same civil scope as larger projects but at smaller acreage. We design grading, drainage, stormwater, access, and permitting coordination for community solar projects across Minnesota and Colorado.
Do you handle utility-scale solar?
Yes. Utility-scale solar projects involve larger sites, more complex grading, more rigorous stormwater design, and more agency coordination. We've delivered civil scope on community and utility-scale ground-mount sites in both MN and CO.
How is solar civil engineering different from a regular development site?
Solar sites have unique constraints. Grading is typically minimized to keep the panel-row geometry consistent. Drainage has to work between rows of panels and around inverter pads. Access roads are wider and stronger to handle equipment delivery. Stormwater BMPs need to coexist with the solar arrays. And the regulatory environment is solar-specific, often involving zoning changes, conditional use permits, and decommissioning plans.
