Default Eavestroughing - Downspout Question

We're in a house with a walkout basement, so the first floor entrance to the door in the basement slopes downwards. We're getting eavestroughing done, and one of the downspouts will be pointing down this slope, from the front of the house, instead of to the front of the house. The company says there's a chance the water can flow back and freeze in the downspout if it were positioned forward. I got quotes from 3 different companies, and all three quoted similar placement for the downspout. I'm wondering if there's any concern for water damage along the foundation of that side of the house, if the downspout points in that direction? Thanks!

Sorry I don't understand the situation. There should not be any location around the foundation that slopes towards the foundation. Can you post a picture or two?

The left of this picture, by the entrance door, is where the downspout would go, facing away from where the picture was taken. The yard slopes down, along the foundation, because of the walkout nature. Don't know if that helps?

I think I get it now. When grading is finished, the dirt should be angled down from foundation to property line. In addition the dirt slopes towards the back yard property line.

There won't be any problems as long as water does not flow towards the house. Also all downspouts should point away from the foundation.

There should still be a swale between the homes to direct water away from the foundation and then down the slope. Codes require that water be diverted away from foundations, not along foundations.

Thanks good2know and Andy. Makes sense now. As long as there is a swale, it shouldn't matter if water is directed to the back. If there isn't, I can take it up with the builder, though I'm sure there will be. Thanks again!

Yes you should. The builder should know that water must be directed AWAY from the foundation, not along the foundation.

Code Rule 9.12.3.2. Grading of Backfill (1) Backfill shall be graded to prevent drainage towards the foundation after settling.

Code Rule 9.14.6.1 Surface Drainage - Lot Grading.
(1) The building shall be located on the building site graded so that water will not accumulate at or near the building and will not adversely affect adjacent properties.
