Environmental Challenges

- Stormwater Management: Westminster manages two stormwater basins: Big Dry Creek and Little Dry Creek. Stormwater runoff from non-absorbent surfaces can carry pollutants into waterways, posing environmental concerns.
- Invasive Species: The city monitors threats from invasive species such as the Emerald Ash Borer and Zebra and Quagga mussels, which can impact urban landscapes and water infrastructure.
