Commercial Storm Drainage & Detention in Louisville, KY

Standing water is never only a nuisance. It softens the base under your pavement, ices over in January, and turns a parking lot into a liability conversation. Drainage work starts with grades, not with product: we shoot the site, find where the water is being held and where it can legitimately go, then quote the fix — regrading, a catch basin and pipe run, a trench drain, or repairs to a detention basin that has silted in. Where a jurisdiction or MSD approval is required, we coordinate it rather than pretend it does not apply.

Who This Is For

  • Property managers with lots or walkways that pond after every rain
  • Facility managers with water entering docks, buildings, or equipment areas
  • Owners with silted-in, eroded, or overgrown detention basins
  • General contractors buying the storm portion of a site package

What's Included

  • Grade survey to identify where water collects and where it can discharge
  • Catch basins, area drains, yard inlets, and cleanouts
  • Trench and channel drain installation with correct fall
  • Storm pipe runs, tie-ins, and connections to existing structures
  • Regrading of pavement, swales, and landscape areas for positive fall
  • Detention and retention basin regrading, cleanout, and outlet repair
  • Erosion control and swale stabilization
  • Coordination with MSD or the local jurisdiction where approval is required

Our Process

  • Shoot the grades

    We survey elevations across the problem area and downstream so the diagnosis is based on where water can actually go.

  • Diagnose and scope

    You get a written explanation of the cause and the options — regrade, collect and pipe, or both — with pricing for each.

  • Permits and coordination

    Where the work touches a public system, a detention structure, or requires jurisdictional review, we coordinate that before digging.

  • Install and verify

    Structures set to grade, pipe laid at proper fall, backfill compacted, surfaces restored, and performance confirmed with water.

How It Gets Priced

Drainage is priced by structure and by linear foot of pipe, with excavation depth, pavement restoration, and tie-in complexity driving most of the cost. Depth is the biggest variable, so we quote the run at the depth the grades require rather than at the depth that makes the number look good. Jurisdictional review or MSD coordination, where required, is a separate line item.

Equipment We Run

  • Excavators and mini excavators
  • Skid steers and compact loaders
  • Trench boxes and shoring
  • Laser levels and pipe lasers
  • Jumping jacks and plate compactors
  • Concrete and asphalt saws for restoration

    A sitework and flatwork sub that returns numbers on bid day, writes a clear scope letter, and works under your superintendent without drama.

Storm Drainage — FAQs

  • Our lot floods after every rain. What is causing it?

    Almost always one of three things: the pavement has no fall toward a drain, the drain that exists is undersized or blocked, or the downstream system is full. Shooting the grades tells us which, and the fix follows from that instead of from a guess.

  • Do you handle MSD coordination?

    Where the work ties into a public storm system or touches a permitted detention structure, we coordinate with MSD or the relevant jurisdiction and build to what the review requires.

  • Can you clean out and repair a detention basin?

    Yes — silt removal, regrading to the design contours where they are documented, outlet structure and riser repair, and stabilization of the side slopes.

  • Will you have to tear up the parking lot?

    A pipe run means a trench, and that means cutting and restoring pavement along the route. We quote the restoration in the same proposal so it is not a surprise line later.

  • Trench drain or catch basin?

    A catch basin collects at a low point; a trench drain intercepts sheet flow across a wide area like a dock apron or a garage entrance. The grades decide which one your site actually needs.

  • How disruptive is this work?

    It is trenching, so it is more disruptive than flatwork but confined to the pipe route. We phase it, keep traffic moving around it, and backfill and plate or restore as we go.
