CIVIL DESIGN SERVICES Key Engineering Group, Ltd. (KEY) has a highly diversified group of engineers who specialize in residential and commercial site development and redevelopment. Many of our engineers have more than 20 years experience in civil site design. Our engineers specialize in permitting, grading and stormwater. We have established strong working relationships with many local municipalities. We believe that quality, consistency and networking are the secret to our successful history in obtaining timely State and municipal approvals for our developments.

KEY's designs incorporate and complement the existing site features and work to enhance the project's aesthetic value to its environment. By incorporating existing natural resources into the project's development, KEY helps you to avoid the additional costs in the sites development. As the project progresses, KEY's responsive design teams quickly develop any necessary changes and then communicate those changes to other project team members.

KEY's approach to each site development project begins with a desire to maximize developable area and satisfy the needs of both the client and the surrounding environment. Every project includes land balance calculations to minimize construction costs and time of completion. KEY also understands the variability in soil conditions and concentrates on balancing the specific earthwork components encountered on each project.
