“In the wake of Hurricane Hilary, the resilience and preparation of our community have been truly evident. Even before the storm approached, our City’s Public Works Department was hard at work, strategizing and implementing preventive measures to mitigate its impact.  Their swift action during and in the storm’s aftermath, from securing flooded zones, unclogging our drainage systems, to inspecting and repairing our vital infrastructure, underscores their dedication to the safety and well-being of our community.
It is during times like these that the strength and resilience of a community are truly tested, and I am proud to say that Lancaster has risen to the occasion.
