Site Improvements: Drainage and Grading

Anyone who owns a home or a property knows how common stormwater and groundwater drainage problems are after a storm or bouts of heavy rainfall. Improper outdoor drainage can lead to a number of headaches for homeowners: rain damage to foundations, soggy yards, and soil erosion issues. JML Landscaping offers a complete suite of drainage solutions to help you deal with these problems. We can help you find the right drainage solution to divert excess water away from your home, including catch basins, channel drains, french drains, cisterns, rain gardens, and proper sump pump and downspout drainpipe connections.

  • Catch Basins and Channel Drains: When designing a proper drainage system, it is helpful to consider the topography of the area, drainage characteristics of the underlying soils, and potential issues from poor surface water drainage. Low-lying and poor-draining spots can benefit from the installation of catch basins and/or trench drains. A catch basin is installed underground and helps take out debris like leaves, garbage, and mud from a drainage system. A channel drain is typically a long, narrow floor-type drain. Both catch basins and channel drains are available with surface grates that can easily handle heavy foot traffic. Decorative grates can be used to enhance the beauty of their surroundings in driveways, courtyards, patios, and other professionally landscaped areas.
  • French Drains: French drains are typically used to draw excess groundwater and surface water away from an area of concern. French drains consist of a perforated drainpipe covered with clean stone. These drains are installed below ground, and the clean stone is covered with filter fabric to prevent the back-filled soil from clogging the stone and drainpipe.
  • Downspout Connections and Rain Gardens: Proper management of stormwater runoff from rooftops is an essential part of an effective drainage system. On flatter, well-draining properties, downspouts can sometimes be connected to rain gardens. By holding and infiltrating rainwater, rain gardens help protect our waterways and reduce flooding. These gardens can be shaped and sized to fit your yard. They also can be attractive landscape features, filled with native plants or other shrubs, trees and plantings that fit your soil, sun conditions and surroundings. In some cases, stormwater runoff from rooftops must be diverted into existing sewer lines. These closed systems are a dependable way of diverting excess stormwater away from the area of concern.
  • Grading: Grading is a critical component of drainage. It can be as simple as sloping soil away from the homes foundation to re-engineering slopes to pitch water to flow in a different direction. One of the most common forms of grading is the installation of a swale. Swales are usually either small, V or U-shaped valleys created to direct water away from something or to a particular location. Swales are typically installed during the process of home construction or landscape improvements. These swales are an important method to dispose of water, however over time site conditions change and these swales sometimes need to be adjusted to to accomidate the changing environment.
