Pollution from homes built near lakes and rivers is harming local waterways in Coeur d'Alene. Impervious surfaces like driveways prevent water from being absorbed by soil, causing pollutants to enter rivers and lakes. This creates problems for wildlife and degrades water quality over time. The document encourages planting natural vegetation around homes, maintaining gardens sustainably, and being open to community ideas to further prevent pollution of Coeur d'Alene waterways.
