Sample interview questions: How do you assess and address potential water runoff and stormwater management in facility planning?
Sample answer:
Assessing Potential Water Runoff and Stormwater Management:
- Site Analysis: Conduct topographical surveys to determine slopes, drainage patterns, and impervious surfaces that contribute to runoff.
- Rainfall Data: Analyze historical and projected rainfall data to estimate runoff volumes and peak flows.
- Soil Permeability: Assess soil permeability to evaluate infiltration potential and determine the need for additional stormwater management measures.
- Existing Infrastructure: Survey existing stormwater infrastructure such as drainage pipes, culverts, and detention basins to identify capacity limitations and potential risks.
- Future Development: Consider future land use changes that may impact runoff patterns and the capacity of existing infrastructure.
Addressing Potential Water Runoff and Stormwater Management:
- Low Impact Development (LID): Implement LID principles such as bioswales, permeable pavements, and rain gardens to reduce runoff and improve water quality.
- Green Infrastructure: Utilize green roofs, rain barrels, and cisterns to capture stormwater for non-potable uses.
- Detention and Retention Basins: Design detention and retention basins to store and release excess stormwater at controlled rates.
