Whether for parking lots, patios, or backyards, drainage is an important part of exterior design. Because much of New York and New Jersey are prone to flooding, having proper drainage measures in place is essential. Our team of landscapers, masons, and plumbing specialists can help design your outdoor space to include effective water exclusion, channeling, and diversion methods. For over 25 years, Advanced Milling & Paving has been providing drainage services to residential and commercial customers in metropolitan NYC, and Northern & Central NJ.
Drainage Solutions for Commercial Parking Lots
Commercial parking lots are generally flat and widespread, which can result in flooding at times. Advanced Site Contractors have extensive experience with designing and renovating parking lots with drainage in mind. From extensive floodwater channel drain systems to permeable pavement solutions, our team is here to help. Advanced Site Contractors is one of the only fully licensed, bonded, and insured exterior planning, landscape design, and site developers serving the greater New York City metropolitan area that directly employs all of our qualified landscapers and builders. Since we don’t subcontract out our work, we can better ensure that you receive quality landscape services.
Catch Basins and Dry Wells
Catch basins collect water and channel it through underground pipes, moving it away from the property. The basins help keep debris from clogging the pipes, often utilizing filters. Basins will then move the water out to the street or a dry well. A dry well is a container that collects the runoff and stores it before emptying. This can help prevent oversaturation after a flood event. Most dry wells work in one of two ways.
First, a leaching dry well allows collected water to leach down into the soil and return to the groundwater. It acts similarly to a French drain. These dry wells are often surrounded by gravel underground to help filter the water and prevent the well from filling with dirt during the leaching process. On the other hand, some dry wells are built with sump pumps. These pumps can retain the water until the pump pushes the water out, usually into the street or into the sewer system. This helps move the water off of the property after the flooding is done.
Channel & French Drains
Drainage systems that use slight slopes to guide the water away include channel and French drains. These drains are designed to help move rain and floodwater away from the home and distribute the water elsewhere. Channel drains use a trench cut with a slight grade to guide the water away from the property. French drains help guide water away while allowing some of the water to seep into the soil below. Redirecting water with channel or French drains can help reduce basement and sub-basement flooding. Water distribution via drains can also reduce the impact that floodwaters have on your property’s foundation over time.
Retaining Walls
Retaining walls offer erosion management and can help guide the flow of rainwater where necessary. Our expert masons use high-quality stones, bricks, pavers, and other mason materials to create our retaining walls.
Grading and Landscape Drainage
The grading (slopes) of your property can be an important measure in draining an area. When designing a paved area, lawn, or garden bed, grading of the space helps prevent water from pooling. Overall, re-sloping the land helps facilitate proper drainage. Proper drainage systems also help limit erosion. Adding a slight grade to paved areas, especially in parking lots, can help prevent water from pooling. Rather, it can help guide rainwater into drains and sewers.
Rain Gardens and Natural Drainage
One way to limit flooding is to make it work for you. Rain gardens use a sloped basin area to grow plants. Floodwaters can pool in the basin and seep into the soil. The roots of the plants can absorb the water in a more concentrated space while giving the water a place to seep down into the soil. The plants will appreciate it and the rest of the property can receive less flooding as a result.
