Fair enough.

Point is still this. Facility is built and turned over to stay at home moms with no capacity for understanding how to maintain it. The HOA fees are set up at such a low point that it can never be enough to maintain it, or even hire people to understand how to maintain it. I'm sure the low HOA fees are a selling point.

Yes, the HOA members/board could vote in higher HOA fees to handle it... but when have you ever known people in South Louisiana to willingly vote for higher fees/taxes?

I’ve never understood the theory that a full pond will hold storm runoff.




It doesn't.

Once the pond level reaches the outfall structure, it's like the pond doesn't even exist from a detention standpoint.

The only detention is when the pond is lower than the outfall. The larger the area of the pond, the larger the retention capacity.

I'm sure someone will correct me if I am wrong but I believe the developers in EBR are only required to design to the rate of rainfall equivalent to a 10 year storm.

Obviously, we have gotten rainfall rates much higher than that in recent rain events.

I’m not sure about EBR but it’s usually 10 or 25 yr

And if you're counting on one of these companies that claim to "manage" subdivisions to have the expertise and acumen to proactively monitor and maintain these retention pond systems you are going to be very disappointed.

i just dont think that is common anymore. the one i was in the dues were like 300/yr when i first moved in and like 400 when i moved. I was a part of the campaign to get the required 70% vote to amend the by laws to allow the by laws to be amended with only a 30% vote. because of how hard it was to get people to vote. They went door to door to get the amount of votes needed to pass. And this was a 20+yr HOA.

Developers develop to maximize profits. Engineers engineer the ponds in accordance with local ordinances and DOTD hydraulics. Contractors build according to the contract.

If you really want to change this issue it's about making development restrictions more stringent, but the same baws complaining about inadequate ponds are usually the same ones complaining about government oversight, how hard it is to get things done, and voting no to millages that could fund projects to remove silt from drainage structures

The problem is not making all development restrictions more stringent.

It's the city of EBR not having any type of master hydraulic plan that considers anything above a 10 year storm.

It's been a developers free for all with absolutely no consideration how the sum total of all development affects the city's overall drainage system.

And, little to no long term maintenance planning or execution to maintain the existing drainage system.

If it's a major HOA like 2,000 or more houses with professional management and dues of $1,000 per year, they know enough to bring in experts to monitor this (I've lived in a place like that).

Short of that... no you are right.

Perhaps. I can tell you a lot of the subdivisions / HOAs being discussed in the greater BR area were developed in the last 20 or so years. A number of them were thrown together after Katrina and were built quickly and cheaply. Many of them are only 50-60 houses on a small street grid of like 2-3 streets max.

I've lived in Katy area where HOAs are huge. It's a completely different ballgame in the BR area. You do have some larger HOAs in BR and they aren't the problems.

Yup. And the cost.

People in LA want Ruth's Chris steaks for Golden Corral prices. It's why they are so susceptible to voting for crooked politicians who tell them they can have that.

Also, shout out to the homies who have bitched about subdivisions but stacked their ditches full of trees and limbs. There are a few that I passed by recently that I wanted to take a picture and go post on their old fb posts.

yes, 100 year events should be considered. I guess that's what I meant by more stringent development restrictions

re: How years of storm water pond construction are causing issues in Baton Rouge metro area
This is the Municipalities fault.

1.) Write ordinance that says HOA's must maintain
2.) Write ordinance that says HOA's must pay
3.) Write ordinance that says HOA's must demonstrate obtaining quotes for cost to pay to maintain
4.) Write ordinance that says HOA's must update quotes for cost to pay to maintain every 36-60 months
5.) Write ordinance that says HOA's must submit maintenance reports every 36-60 months

Super simple sh!t

Other municipalities in Louisiana already do this and it works like a charm. That this is an issue in Baton Rouge is a signal of the weakness of the UDC and the control the Development Community has over the political establishment.

This is not the case everywhere.

They also use the soil that was removed from the bottom of the pond to build up the land around the pond to meet base flood requirements. This meets "no net fill" ordinances, but reduces net storage volume by that exact same volume below the water surface.


Not true. Fill mitigation (no net fill) volume can only be counted above the outfall control structure. So, if you dig below the outfall structure for a wet bottom pond, you can only use that volume to fill above base flood elevation. Therefore the net storage volume pre vs post would be net zero below bfe.

Btw, long time lurker, first time poster. Sup, baws.

TIL there’s such a thing as a detention pond.

quote:


Wouldn't silting in reduce the TOTAL capacity of the pond, and if the normal water capacity is unchanged, wouldn't the freeboard capacity be reduced?


No, because there is no capacity below the outfall control structure which is where the siltation is occurring. In terms of detention, nothing below the normal pool is counted for detention or fill mitigation.

Detention in EBR is required for a 25 yr storm since 2017. Detention in ascension requires a reduction of the 25 yr to the 10 yr, about a 17% reduction, since 2018. EBR just changed again to a 10% reduction in the 100 yr fr any projects with more than 25% of the land in the flood zone.

100 yr fill mitigation, net zero fill, had been an EBR policy since 1987. Again, that is replacing air for air. So only the dirt above the normal pool counts towards fill mitigation.

No matter how stringent you make new development requirements, the same people are going to keep flooding. Most developments built in the last 25 years did not flood in 2016 and may 2021. Those developments have detention, do 100 yr fill mitigation and are built 1' above BFE. Developments post war to 1987 are the ones flooding since they were not built to any standards. New development is not the issue. Maintenance of the canals and rivers is the main issue. We have been talking about the 5 tributaries project that they are about to do since the 1983 flood. Almost 40 years and it already was bad then.

re: How years of storm water pond construction are causing issues in Baton Rouge metro area
This has always baffled me, you dig a pond to offset the construction and then the pond stays full of water.
