$66-million in drainage projects to fight flooding

(ran NTP edition)

It was raining, it was pouring, and no thanks to El Nino, it was flooding.

And while the record rains may be behind us, reminders of the water damages still remain.

Rather than wait for the problems to worsen, the County Commission agreed last week to a three-year, $66-million plan that would pay for stormwater drainage work in some of the areas worst hit by heavy rain. About $15-million of the plan will be slotted for new neighborhood projects that range from retention ponds to drains and ditches.

The rest of the money will be spent on changing building codes to prevent flooding and improving existing drainage systems.

Commissioners have promised not to raise taxes to foot the bill, and they have pledged to complete the work in the next three years.

These are some of the new projects planned in northern Hillsborough:
