You have a good point sir... But you are still talking about the causes.

Let look at for an individual developer planning to build a house in these high prone area, what method of construction would you advice to save the building during time high flood?

I would suggest that all building in these area should come with a basement, where the ground floor serve as car garage and the first living space is raised at least 3m above the Natura ground level. During flooding period, nothing will happen with your properties inside the house.

The group floor will only columns support the first living space. These columns will be designed as unbraced column, with water resistance paint to protect them against constant contact with water.

This is the county (local government) that I live in. You're not going to just build anyhow.

The government has failed Lekki but the homeowners are culpable too. Please play around with that mapping site.

The homeowners won't build the required type of house because it's look ugly. You know our people.

The first floor of at least all commercial building in Lekki should be a parking garage.

You get it!

All properties in Lekki and all other flood prone areas should consider doing a basement (flood proofed) in order to keep their property afloat during flash floods.

In actual sense, a basement will make more sense than the traditional cut-and-fill found nations which we are accustomed to in these areas.

The basement will amongst other things do the following:

1. Eliminate the need for sandfilling which covers about 8% of construction cost in this areas. The excavated soils from the basement can be used to backfill the compound or raise up levees around the property. Good solution yet cheap.

2. Big Savings on foundation cost. Some may ask how is this possible? Basements do not require internal partitions to serve its intended purpose. As a result, there are few concrete to pour (the slab and the walls). The cost of waterproofing a basement is almost negligible when you compare the benefits. Also, the additional space gained can add more value to the property and serve so many other purposes.

3. Effective Flood Protection. A basement if well designed and constructed can effectively prevent flood in most homes in Lekki and people will live without worries.

Let me leave it here for now. More to come.

Let's take a look at the design attached.

Developers and small communities with common goal can implement this simple design to deal with flooding and drainage issues.

But how possible is this in an area where government do not control the lands? How possible is this in communities where Omo Onile determines the setbacks, roads and right of ways.

The more the setbacks to properties, the lower the flood level except in buildings which were already below flood level.

Again, government has a lot to do to address this issues.

@successmatters . Listen and listen very carefully . Nigeria is not USA or abroad . Learn how to respect elders . Enu go ?

I think this overemphasizing on floods is just being used by one particular person to divert attention away from himself (reminds me of the lekki gardens stuff as well, and how he was the chief investigator /spokesman), build sensible drainage and maintain it well and floods will be drastically reduced. Both internally in ones house and also in the community i.e roads, not building on flood plains or drainage channels etc.

Even in developed Western Europe, they have floods that wipes away a whole community, usually caused by heavy rainfall and properties close to waterways or in flood plains.

Abdulwastec, pls explain what you mean by basement, basement to me is like an underground space, usually below the road level.
What it sounds as though you are referring to is to build a house on like what I call loads of Pillars or whatever technical term you guys call it, mainly used in commercial builds whereby the ground floor is like the parking space. Please confirm.

My pictures below is trying to explain what I mean. I quite like the idea of building on pillars, but will the entire groundfloor be only pillars or can it have some living space like servant quarters there etc / gym / swimming pool etc. How can the space be better used, and reduce the risk of flooding, just building a house with pillars on the entire groundfloor is somewhat boring IMO and would be an architectural eyesore especially in a residential build (imagine like 50 pillars)

You are right sir. I may have been wrong using the term basement because it means building below grade.

Raising the building higher and supporting with pillars will work. This space below can then be use for the gym, security house and swimming pool. The idea is to have functionality that will not be too affected in the event of flood.

You are right on point sir

You took the words right out of my mouth,
This is the most practical and easily actualizable defence.... "ELEVATION" If you can't control the flow of water in your direction control your elevation/position relative to water level when the floods hit.
Note the use of the word "defence" .
you cannot prevent coastal flooding it's inevitable , the earth is bruised and bleeding....especially at an individual level, and in a country like this. But you can buy/provide yourself some defence.

Those with a more robust budget can build a ramp That goes from the side to rear of the house as pictured below, to serve as a safe spot for the cars during the flood and use the ground garage when the threat abates. You can even connect the ramp like an elevated porch or balcony to your first floor and simply park your car and stroll into your back balcony from the ramp.

A well written piece of valuable Information with nice sketches to back them up. This is the most economical and practical solution to the problem.

Thanks,
In my opinion the pillars don't even have to be so conspicuous. There's always some intelligent way of framing it.. with walls or some sort of cosmetic covering that helps improve aesthetics

In addition to forcing new builds to use the first floor as underground parking, the city can also create two or three reservoir parks.

Reservoir parks are low laying recreational areas that can be closed off during rain and used to store rain water and then pumped out or a controlled escape downstream.

I live next to the Santa Fe Dam recreation area, a 70 acre potential lake - that's a lot of water holding capability.

This is good!

I've seen basement, underground reservoirs, house built on stilts, stormwater drainages, raised floors, ramp.
Is there any more design consideration?

Let's keep it coming.

Thanks abdulwastecx, Egunmogaji, allCopacetic (my eyes still on you), Maverrick and everyone who has chip in some very good comment

Any good proposal for those who already built their houses below flood level?

How do you flood proof your house in event of flash flood?

_________
Ikota complex by the Israeli HFP had good drainage design yet it gets flooded during heavy downpour.
__________
Segcymoor suggested cutting the lintel, raise the door and increase the height of the entryway.

__________
There's a house in Thomas estate, Ajah that never gets flooded when all other houses are affected by flash flood. The owner implemented a very creative drainage design.

__________
Any more?

@ mavverick, you can help by telling us the status of this build during the heaviest downpour that flooded the whole of Lagos.

It's our build which is clearly below flood level and we will appreciate feedback (good or bad) from clients who took to instructions early enough.

The above pictured project na wa o. How can somebody build inside river? Is it due to too much money in the client's pocket or what?

Funny enough, the owner didn't see the water when he bought the land.

But this is what we are talking about. Fix the issue. Stop looking for help where there is none. The longer it stays, the worse it becomes.

Thank God the owner listened to the advice to fix the water issue before proceeding with the build.

I was at this site in Ologolo, infact, I was meant to buy the 2 plots but got a better place. I even took some pictures when you were working. But wouldn't the job have been neater if you had sand filled before building? I saw how the carpenters struggled with the water. It was nice seeing the determination of the work force on ground.

Now, I know. You were the man that came in the jeep. I was told someone came...

Concerning Sandfilling before building, it's a long story you won't want to hear.

However what we did first was to build flood protection round the existing fence to prevent water from other site from coming into the plot. Then, we faced it head on.

Some clients won't stop until nature put them to stop.

Chief brabus, do you mean these 3 pictures are from the same project site.
Is it possible for you to post the finished build.

I'll defer that request to the owner. But if he grants the permission I can do 5 minutes video from the main Ologolo road to the site.

I'm sure if it didn't work, this page will have reach 800 and the whole Nairaland would be shaking by now.

This is attention seeking in the attached chat msg. Living a double standard. Your piece above will make a good point without necessarily attaching the first paragraph.

Maybe you want to share how effective Sandfilling at the right time helped you secure your structures built by NextHome despite building below flood level and less than 1.5m from government canal.

And some people will sit down there taking solace in your comforting words while you're busing fixing your own build behind the clouds. SMH!
