Utility-scale solar

Erosion control & seeding for utility-scale solar construction.

Thousands of disturbed acres, long slopes between tracker rows, basins and swales that have to hold before the rain does, and a stabilization deadline that doesn't move. That is where we work.

Why solar is different

A solar site is a hundred small sites with one deadline.

Solar construction disturbs more ground than almost any other project type and releases it in pieces: a block is graded, piles go in, racking follows, and the ground between rows has to be stabilized before the next storm while the next block is still being cut. Perimeter controls run for miles. Basins and swales sit at the bottom of long slopes. Wetland buffers and fence lines carry 30-foot exclusion zones that have to be measured, not guessed.

The permit clock doesn't care about any of that. Stabilization starts the day grading stops in an area and finishes within 14 days (7 in sensitive waters). Miss it and the inspection report fills up, the owner's compliance team gets involved, and the EPC's schedule slips.

We built the company around this job. Our takeoffs come from the civil set and the KMZ, our crews follow grading release by block, and our reporting is by area so the superintendent always knows what is covered.

TakeoffBasins, swales, buffers, rows

Measured from plans and KMZ before we quote. The proposal lists areas, not a lump sum.

SequencePerimeter → basins → buffers → rows

Controls in before grading, slopes and swales first, then the ground between rows as racking releases it.

ProductsFGM where it matters

Flexterra HP-FGM on basin sides and steep swales, BFM or hydraulic mulch between rows, permanent seed on final grade.

Scope on a solar job

Everything stormwater, start to NOT.

Before grading: silt fence and perimeter controls, construction entrances, inlet protection, washouts. During grading: check dams, wattles, temporary seeding of stockpiles and phased areas, basin and swale stabilization with FGM. After racking: permanent seeding between rows with the project PLS mix, buffer and fence-line stabilization. Through the job: SWPPP maintenance, post-storm repairs, sediment removal. At closeout: BMP removal, final stabilization documentation for the Notice of Termination.

We have worked for EPCs and sitework contractors on utility-scale sites in Kentucky, Tennessee, South Carolina, Georgia and West Virginia. We don't publish client or project names; we publish acres. See recent sites.

FAQ

Straight answers.

What is the 14-day stabilization rule?+
Under the EPA Construction General Permit and most state permits, stabilization must begin immediately when earth-disturbing activity stops in an area and be completed within 14 calendar days (7 in sites discharging to sensitive waters). Phased sites apply it block by block.
Can you follow our grading release schedule?+
Yes. We staff and stock for phased release and work from your lookahead. Our crews are on our own trucks, so re-mobilizing to a new block is a drive, not a contract.
Do you work between the tracker rows?+
Yes. Hydroseeding between rows after racking is standard scope; we size equipment and hose runs for row spacing.
What do you need to quote a solar site?+
The civil set (grading, E&SC sheets, details), the KMZ or shapefile if you have one, the spec section for seeding and erosion control, and a rough schedule. We return a quantity-based proposal.
Do you handle the Notice of Termination documentation?+
We provide the final stabilization record and photos the permit holder needs to file the NOT; filing stays with the permit holder.

Send the civil set and the lookahead. We'll measure it and come back with a number by area.
