Drainage easement vs retention pond..advice needed (sales, home)

[rrali33tt]

We are under contract to purchase a new construction home and the sales agent had told me that there was a dry retention pond behind the home. I was doing some research today and noticed other builders in the area are calling this piece of land a "draining easement" and not a dry retention pond and there is an actual dry retention pond across the street from the "draining easement". This "draining easement" is about 200 ft long as it is behind my plot and 3 other plots. I do not know of any easements on the actual plot I purchased.

What is the difference between a "draining easement" and a retention pond?

Will this affect my home value? Could I see erosion of my soil because of this draining easement?

The sales person said it was a dry retention and that would only get water in it if there were extremely heavy rains and that it would drain quickly. I feel like i have been misled on what is behind my property. I am waiting for them to confirm the easement does not actually cross my property line as well.

Any other advice? Should I try to get a different plot?

If there is a drainage easement in your property or any easement, you'll have to follow whatever rules are set forth by the easement. So, a crew from the city might be able to go to the drainage pipe or whatever and fix. Also, you might not be able to do anything on whatever that part of the land is. It just depends on how the easement reads. Usually an easement is only on a piece of your land and if it's towards the back or towards the side of the property, then it shouldn't be a big deal. It's usually more of a bigger deal if it's in the middle of the property. But, basically a drainage easement is about allowing a certain pipe or drainage area to clear of anything, since it is meant to benefit the whole community by not flooding the streets.
