DGL has built a trustworthy reputation for delivering high-quality services to the residential sector. The scope of our experience ranges from single-family custom homes to multi-family developments, subdivisions, condominiums, and senior housing developments. We work closely with developers, homeowners, lenders, realtors, architects and contractors, to create solutions that realize their visions, all while meeting their budgets and the local and state regulations.

Our project leaders perform oversight of residential projects from our clients’ wish-lists through project completion. This starts with the survey team utilizing GIS data sources and the latest survey and mapping technologies, including GPS, Robotic Total Stations and Scanners to generate base mapping used to generate drawings from concepts to preliminary plats, full construction plans, construction staking, and as builts. These plans contain elements such as contours, mapped wetland areas, soil types, floodplains and existing utility mains, all of which are imperative to successful residential design.

DGL’s engineers use 3D modeling software to accurately design entire sites with roadways, building pads, walks, multi-purpose paths and trails, and structures. These models can then be used to show surface model contours, spot elevations, and slopes. All these aspects are imperative in determining a balanced earthwork site, determining detention volumes, and drainage areas.

Being in Northwest Ohio, we frequently hear people say, “When it rains, everything floods.” Our philosophy is that if the site is designed and modeled properly, it does not have to flood. DGL balances the earthwork while providing positive fall to drainage features which are designed to control the runoff. We utilize software to model the rain events and route the stormwater through detention and retention ponds to balance the rate of runoff and the stored water volume. The drainage system to get the water to the ponds is also designed using a combination of structures pipes, drainage channels, and other conveyance features appropriate for the water quality and quantity.

Because of our experience across the region, we are knowledgeable in the variations of building codes and zoning ordinances to ensure compliance with local and state regulations. We also relieve the burden of application processes by serving as our clients’ liaison to obtain appropriate project permits. Our engineers are a go-to resource for on-site septic/sewer systems design, as well as solving stormwater drainage issues. Our retaining wall portfolio is impressive and includes solutions that are unique and attractive.
