Stormwater Management Services in Central Pennsylvania
JDI Site Solutions builds, inspects, and maintains stormwater systems for commercial sites, municipalities, and developers across Central Pennsylvania. We work from approved plans through construction, then stay on afterward for the inspection and maintenance the permit requires.
Compliant Stormwater Systems for Commercial and Municipal Sites
Stormwater work in Pennsylvania is permit work. A project disturbing an acre or more falls under DEP Chapter 102 and needs NPDES coverage, with an erosion and sediment control plan and a post construction stormwater management plan behind it. Sites between 5,000 square feet and an acre still need a written E&S plan in place. We build what those plans call for, including detention and retention basins, catch basins and inlets, underground conveyance, outlet structures, and erosion control measures, installed to the elevations and specifications on the approved drawings.
Most of our stormwater work begins with plans already sealed by your engineer and reviewed by the county conservation district. We build to them, coordinate with the design team when field conditions differ from what is drawn, and keep the documentation in order for inspection. Our crews come out of a full site work operation covering excavation, culverts, and waterway restoration, so the earthwork behind a basin is not a subcontracted unknown. We carry PA Contractors License #PA178908 and $10 million in insurance coverage.

Keeping an Existing Stormwater System in Compliance
A stormwater system is a permanent obligation rather than a closeout item. Basins silt in, outlet structures clog, inlet grates fail, and embankments erode, and a system that no longer performs the way the approved plan said it would is a compliance problem before it is a drainage problem. We handle scheduled maintenance on existing systems, including sediment removal, debris clearing, structure and pipe condition checks, embankment and spillway repair, and reestablishing erosion control on failed slopes.
We also work on systems that were built before current standards or never performed as intended. That covers retrofits on older commercial properties, repairs to basins and conveyance that have deteriorated, and bringing a site back in line with what the plan requires after a failed inspection. Owners with recurring obligations can put maintenance on a set schedule so the work is documented and done ahead of inspection rather than after a notice arrives.

Frequently Asked Questions
Permit thresholds, maintenance obligations, and what happens when an older system stops performing account for most of what commercial owners and municipal staff ask us. Here are the answers we give most often.
What stormwater regulations apply to a commercial project in Pennsylvania?
Earth disturbance of one acre or more triggers NPDES permit coverage under DEP Chapter 102, which requires both an erosion and sediment control plan and a post construction stormwater management plan. Between 5,000 square feet and one acre, a written E&S plan is required on site. County conservation districts handle review under delegation from DEP.
Do you design the system or build from our engineer's plans?
We build from plans prepared and sealed by your engineer and approved through the permit process. Our role is construction, coordination with your design team when field conditions differ from the drawings, and maintenance afterward. If you do not yet have a design team in place, we can point you toward the process and work alongside whoever you engage.
How often does a commercial stormwater system need maintenance?
Twice a year is a reasonable baseline for most Central Pennsylvania sites, with additional checks after significant storms. Freeze and thaw cycles and heavy spring rain are hard on inlets, outlet structures, and basin slopes here. Your permit or municipal ordinance may set a specific schedule, and we work to whatever that document requires.
Can you bring an older system back into compliance?
Yes. We retrofit and repair systems on existing commercial properties, including basins that have silted in, structures that have deteriorated, and conveyance that no longer moves water the way the plan intended. We assess what is there, identify the gap against current requirements, and work within the constraints of a site that is already built.
How long does a stormwater installation take?
Scope drives the schedule. A straightforward commercial system often runs a few weeks, while a larger municipal project or a multi phase development can span months. Weather and inspection timing both factor in. We give you a realistic window up front rather than an optimistic one, and flag schedule risk as soon as we see it.
Do you work with municipalities and developers?
We do. Township and borough stormwater work, commercial and industrial sites, and residential subdivision development are all part of what we handle. On a residential development the obligations are the same as any other regulated site, and we work with the developer and engineer the same way.
