Property w/basement has Drainage easement within back yard (new house, buy)

[hiworld1]

Hi,
I am in the market for new house. I like one house but after receiving survey, I find out that there is a "Drainage easement" within the property (approx 20 ft from back of the house). I has also notice a open drainage (perhaps storm drain) running across rear boundary and one side of the property along with "head wall" on one side of the property within lot.

picture of head wall as i seen at this property:

Headwall is also about 15 feet from side of the house within property.

This house has the full basement and its finished. will there be any problem because of "drainage easment & head wall" being inside back yard? I talk to the people living next door and they had a water up to 2 feet in their basement last year because their sump pump was failed to work. the sea elevation of this location is 78 feets based on google map. Entire developement is only 2 years old so there is not much history available except this guy who had water in his basement last year.

We really like the property but above reasons make me nervous about putting an offer on this house.

I will appreciate if anyone can share their knowledge regarding "drainage easment" within property and possibility of getting water in a basement.

Will these issue impact on price of the property in future?

thanks,

Well, if he had water in his basement, it's a good bet that the same would happen to yours if your pump stopped working. I really can't imagine having such a large drainage structure that close to the house- the amount of water that'll run through that thing in a decent rain storm isn't something I'd want to be anywhere near.

A finished basement which will probably take on water at some point? What a mess that will be. Honestly, I would not buy that property. I wouldn't want to look at that big drainage pit in what was supposed to be my yard. You will probably have to sell this house some day. I doesn't look like a positive feature to me.

Thanks guys. i was thinking the same. but house is nice so, decided to get peoples thoughts on this.
looks like it is risky to have this property.

Many residential properties have drainage easements but they look nothing like that. I would not buy a property with that structure, looks more like a commercial drainage system built to accept sweepage from a large structure.

You should call the township planner and engineering department to ask them about this easement. A drainage easement is supposed to take water away from the house and the houses should be graded such that water flows to the drainage easement.
