Special attention must be paid to LID installations in arid environments. These areas are dry with large temperature differences between summer and winter, day and night. Due to concerns of poor winter performance and freeze-thaw cycles, LID installations in cold climates are not as common as warmer climates.

These installations can be specifically designed to address rapid freeze/thaw cycles, semi-arid conditions, and intermittent and unpredictable rainfall patterns.

EPA Region 8--Mountains and Plains
While the Washington Stormwater Center is firmly within the boundaries of EPA Region 10 (The Pacific Northwest), there are many valuable lessons that can be learned and applied from other EPA regions, specifically region 8. This region encompasses many mountains and plains and has experience with arid and cold LID installations.
