Is massive planned growth wise, considering the drainage and flooding issues? (Trinity: new home, mall)

[The Villages Guy]

With 10,000 new homes and a huge mall planned in the Trinity area, I wonder if that is a wise move with all the drainage issues and flooding they have been having up there?

I wonder if the plans for these things will be reevaluated?

The flooding in Trinity was specifically right by the rivers and streams. Not much you can do about that. It happens every time a major rain happens

Seriously not an issue that isn't already accounted for.

I see in wiki that Trinity is at an elevation of about 20 ft so sea rise would have no direct affect in the foreseeable future of say 100 years (other than maybe potable water supply if local wells are contaminated by sea water intrusion, whatever).

We know now--only recently proven--that our rains are increasing due to climate change but I doubt we yet know precisely how that might play out so tough to plan for but we can guess it will be more than it's been so design accordingly.

And all large developments come under various reviews, city if incorporated, county if not and very large developments called DRI (Development of Regional Impact) come under state review as well as county and cities. So within all that drainage issues are accounted for.

And just googling real quickly it looks like this might be Pasco's ordinance on that...

CHAPTER 900. DEVELOPMENT STANDARDS
SECTION 902. STORMWATER
902.2. Stormwater Management Requirements
A. Intent and Purpose
It is the intent and purpose of this section to reduce existing and future flooding problems, improve surface water quality in the County, and protect the functions of natural features and surficial aquifer recharge.
B. Applicability This section shall apply to all development where any portion of the development is within the jurisdiction of unincorporated Pasco County.
etc etc etc

I haven't read all theirs specifically but generally a developer is required to keep what rain falls on their property in their property. That's done with grading and drainage pipe as required and curbing etc., all leading the water to retention ponds built large and deep enough to handle probably up to a 100-year event, however that's defined.

I ask, as in this case there was actually some flooding accuring in other locations as well. Turns out some areas are one to two feet below sea level.
