Patrick Boulas is an Environmental Specialist with the Environmental Health and Safety Department. His role in the department focuses primarily with coordinating UNL’s Storm Water Management Plan throughout both City and East Campus. The program he coordinates is charged with reducing stormwater pollution to receiving water bodies.

Post-construction stormwater controls are structural features installed in the environment that are designed to reduce the impact of stormwater runoff to receiving water bodies. When cities or campuses grow and develop, stormwater quality and quantity impairments can occur. These impairments are considered pollution and can come in a variety of forms and sources. For example, stormwater pollution can originate from new and existing parking lots, roads, and buildings. Increasing a site’s impervious surfaces can increase the amount of stormwater runoff, which can negatively affect receiving waters. It is important to understand that when we alter our landscape we also alter stormwater runoff in some way.

At UNL, potential impairment is mitigated by requiring the design and installation of post-construction stormwater controls for new and re-development projects that are greater than ½ acre in size. Popular post-construction stormwater controls currently serving City and East Campus include permeable pavers, bioretention basins, and stormwater collection systems.
