Stormwater & Drainage Construction in Central Florida
Retention and detention ponds, exfiltration trenches, underdrains, SWPPP compliance, and storm pipe systems — built to water management district permits and designed to perform on Florida's challenging flat terrain.
Why do Central Florida sites need engineered stormwater systems?
Florida's flat terrain, intense summer rainfall, and shallow water table mean runoff has nowhere to go unless the site is built to move it. Water management district permits require retention ponds, exfiltration trenches, or conveyance systems sized to hold and treat that runoff. Earthscapes builds these systems to SJRWMD and SWFWMD permit elevations — and verifies stage-storage during excavation, not after.
Drainage Problems That Kill Schedules
Stormwater issues don't wait until after CO. They show up during construction, during inspections, and on the first heavy rain. We build systems that pass inspection and actually drain.
Ponding on finished grades due to near-zero slope
Central Florida's topography averages fractions of a percent across many sites. Imprecise grading creates low spots that pond water, fail inspection, and generate warranty claims.
Water management district inspection holds
SJRWMD and SWFWMD conduct construction inspections and can issue stop-work orders for improper erosion control, incorrect control structure installation, or deviation from permitted plans.
Retention pond volume shortfalls
If pond excavation doesn't reach the permitted stage-storage volume, the project can't demonstrate compliance. Verifying elevations during excavation — not after — prevents expensive re-work.
Erosion and turbidity during construction
Florida's summer rain events are intense and frequent. Inadequate BMP installation or maintenance leads to sediment leaving the site, regulatory violations, and potential fines for the permit holder.
Stormwater & Drainage Capabilities
We self-perform the full stormwater scope from earthwork through pipe systems, structures, and final stabilization — no hand-off gaps.
Retention & Detention Pond Excavation
Wet and dry retention ponds excavated to permitted stage-storage volumes. We grade side slopes, shape littoral zones, and install control structures per the approved water management district permit.
Exfiltration Trenches
Perforated pipe systems in aggregate-filled trenches that allow stormwater to percolate into Florida's sandy soils. Used where site geometry limits pond footprint.
French Drains & Underdrains
Shallow underdrain systems installed beneath pavement and landscaped areas to intercept sub-surface water, reduce pavement saturation, and protect subgrade bearing capacity.
Swales & Sheet-Flow Grading
Florida's near-zero grade means every tenth of a foot matters. We shape roadside swales and sheet-flow conveyance paths to direct runoff toward collection points without ponding on adjacent properties.
SWPPP Installation & Maintenance
Silt fence, turbidity barriers, inlet protection, and stabilized construction entrances installed per the project's Stormwater Pollution Prevention Plan. Inspection logs maintained throughout construction.
Control Structures & Outfalls
Concrete and precast control structures, bleed-down orifices, weir walls, and armored outfall dissipaters installed to regulate discharge rates to permitted levels.
Pipe Storm Conveyance Systems
Reinforced concrete pipe, HDPE, and corrugated metal pipe systems with inlets, junction boxes, and manholes connecting impervious surfaces to water management facilities.
Post-Construction Stormwater Management
Final grading, slope stabilization, littoral planting coordination, and pond-bank protection to prepare retention systems for long-term operation and permit compliance.
How We Build Stormwater Systems
Permit & SWPPP Review
Before mobilizing, our team reviews the water management district permit, approved construction plans, and the SWPPP. We confirm erosion control installation requirements and stage our BMPs for day-one mobilization.
Erosion Control Installation
Silt fence, turbidity barriers, inlet protection devices, and stabilized construction entrances are installed before clearing begins. Florida DEP and water management district inspectors may be on-site early; we are ready for them.
Mass Excavation & Rough Grading
Pond basins are excavated to permit stage-storage. Earthwork is balanced on-site where possible to minimize haul costs. Borrow areas and fill placement zones are coordinated with the geotechnical engineer.
Pipe Systems, Structures & Control Works
Inlets, storm pipe, junction boxes, and control structures are installed per the permitted construction set. Pipe grades are verified before backfill; control structure elevations are checked against permit drawings.
Fine Grading, Stabilization & Closeout
Pond side slopes and swales are finish-graded, seeded or sodded per the landscape plan, and littoral zone planting is coordinated. SWPPP records and as-built documentation are compiled for permit closeout.
Industries We Serve
Service Area: Central Florida
We perform stormwater and drainage construction within approximately a 100-mile radius of the Greater Orlando / Lake County area — spanning SJRWMD and SWFWMD jurisdictions across Marion, Sumter, Citrus, Hernando, Pasco, Hillsborough, Polk, Osceola, Orange, Seminole, Volusia, and surrounding counties.
