buffer because of the removal of two native trees. The applicant agreed.
Questions and comments from the audience:
Kenneth Haydo. 14 Cooke Road, stated that he is concerned about flooding in the area. He is
also concerned about how water will be contained during construction as well as what will
happen to the water when they need to drain the pool. Mr. Nitzsche explained to the neighbor
that the pool will have effect on the groundwater and will not cause an increase in flooding.
During construction, they will use proper dewatering techniques if needed. Thomas Libretto
explained that will a gunite pool, there is no need to drain it. However, if they do need to drain it
for some reason, they will call a pool company to pump it into a truck.
