Low Impact Development (LID) is a specialized approach to land development that aims to minimize the impact of man-made structures on the natural environment. LID techniques include the use of permeable pavement, green roofs, rain gardens, and other measures that encourage natural water filtration and the preservation of vegetation. LID is becoming increasingly popular as developers and municipalities seek to reduce the negative impact of development on the environment, and as such, LID has become a specialized skill that requires training and expertise.

Municipal or urban engineering is a specialized field of civil engineering that deals with the design, construction, and maintenance of infrastructure systems in urban areas. This includes roads, bridges, water supply and sewage systems, public transportation networks, and other public facilities. Municipal engineers work closely with city planners, government agencies, and private contractors to ensure that urban infrastructure is designed and implemented to meet the needs of urban populations efficiently and sustainably. Successful municipal engineers must have a solid understanding of urban planning, environmental science, and the construction industry.

Roadway Design refers to the planning and development of road layouts that support safe and efficient movement of vehicles, cyclists, and pedestrians. It includes the application of geometric standards, traffic needs, drainage considerations, and site conditions to define roadway alignment, width, and features. In work settings, it is used to prepare design documents and coordinate roadway improvements for new construction, expansion, and rehabilitation projects.

Stream restoration involves the application of specialized skills and techniques to improve the health and functionality of degraded or damaged streams. This may include activities such as stabilizing stream banks, restoring natural flow patterns, and reintroducing native vegetation and aquatic species. It requires expertise in hydrology, geomorphology, ecology, and engineering, as well as knowledge of local regulations and permitting requirements. Stream restoration is typically undertaken in partnership with stakeholders such as landowners, community groups, and government agencies.

Water/Wastewater Engineering is a specialized field within civil engineering that focuses on the design and management of water supply and wastewater treatment systems. This includes the collection, treatment, and distribution of potable water, as well as the treatment and disposal of wastewater. Water/Wastewater engineers also play a critical role in ensuring public health and safety by developing and implementing systems that meet regulatory standards and protect the environment.
