New construction sites are a different animal when it comes to drainage. There's no existing landscape to work with, grades are still being established, and the soil is loose and disturbed. If you don't get the drainage right early on, you're setting the homeowner up for water problems that get exponentially harder to fix once the yard is finished.
Here's what we were working with - a sloped lot on a brand new build in Wappingers Falls, NY. The home was still under construction, which actually works in everyone's favor. Running drainage pipe through a raw, open site is far cleaner than trying to retrofit a finished yard. We had full access to trench and route pipe exactly where it needed to go, without tearing up sod or hardscaping.
The trench runs a long path down the slope, with PVC pipe seated and aligned throughout. Getting that consistent slope along the pipe run is critical. Water doesn't move on its own unless the grade encourages it. Too flat and you get standing water in the pipe. Too steep and you can erode the bedding material. We dial that in carefully on every install.
On a sloped lot like this one in Dutchess County, managing surface runoff is especially important. Without a proper outlet system, water follows the path of least resistance - which is usually straight toward the foundation or into the garage apron. Getting this infrastructure in the ground while the site is still open means the homeowner won't be dealing with those headaches after move-in.
