A land development civil engineer helps plan residential, commercial, industrial, or mixed-use developments. In this role, you determine the feasibility of a development project and assess the land to ensure that it can support the planned development. Once the possibility is established, you design the infrastructure, including streets, utilities, waste management, drainage, and other systems by creating drawings or using modeling software to visualize your plans. You also coordinate with other architects and engineers involved in the project. A civil engineer must ensure that infrastructure plans meet zoning requirements and do not conflict with other municipal regulations.
