allowing subdivision regulations concerning water supply.

This bill allows local planning boards to include specific rules in their subdivision regulations regarding water supply and costs. It requires developers to conduct water supply studies and ensure enough water exists for current and future land uses, while also setting minimum testing standards for private wells. These requirements apply to new subdivisions but exclude large community water systems and major groundwater withdrawals already regulated by state law. Additionally, the bill permits planning boards to charge reasonable fees to cover administrative expenses and notification costs associated with reviewing subdivision applications.
