Certified Professional In Erosion And Sediment Control (CPESC) refers to specialized knowledge and practice in planning, evaluating, and managing measures that reduce soil loss and control sediment movement. It is used to assess site conditions, support compliance with environmental requirements, and guide the selection of control methods during land development, construction, and land restoration work. The skill also supports inspection, documentation, and coordination of erosion control activities to protect water quality and stabilize disturbed areas.

Geotechnical Investigation refers to the process of assessing the physical and engineering properties of soil and rock in a specific area to inform construction and engineering projects. This skill involves the collection and analysis of subsurface data through methods such as drilling, sampling, and laboratory testing. Knowledge of Geotechnical Investigation is used to evaluate site conditions, determine soil stability, and inform the design of foundations and other structures, ensuring safety and compliance with engineering standards.

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.

Stormwater management is an engineering practice focused on managing and mitigating the effects of rainfall and other natural water sources. This involves designing systems and techniques to manage stormwater runoff, improve water quality, and prevent flooding. It requires specialized knowledge in hydrology, engineering, and environmental science. Effective stormwater management is critical for maintaining the ecological health of our waterways and protecting public safety and property.

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.
