flooding during heavy rainfall, and existing drainage infrastructure has proven insufficient. I have enclosed a
photograph from October 2025 that clearly documents these conditions. Additional impervious surfaces
and increased runoff from a development of this size will likely worsen
flooding requirements. Both
BMP1 and BMP2 will be equipped with a waterproof liner system to prevent any contamination
from the groundwater. This system will be anchored with additional stone to prevent buoyancy.
Inlcuding the baseflow should be not be required
