Hi Jeff,
The city building inspector and I made a site visit to the 1040 single family residence project at the
request of the plumber for the project. He had some questions about installing a sump-pump for the
area drain at the basement window well. The following issues have become apparent with the
excavation work that has recently been performed.
1.The roof storm drains appear to be connected to perforated piping approximately at mid-height
of the basement foundation wall. The city Engineering department has made at least three site
visits regarding this and related issues, and left a correction notice, as well as a violation notice
to correct the roof drainage issue. The problem of water intrusion into the basement could
develop if this issue is ignored. The roof storm drains are required to be installed into an
approved tight line material and tested according to UPC1109.1.
2.Exposing the basement wall by the excavation, it is now apparent that the basement foundation
was not dampproofed as required by IRC406.1, from the footing level to grade. The foundation
will need to be exposed and dampproofed by an approved method, and inspected by the city
prior to cover.
3.At the time of yesterdays visit, the bottom of the footing beneath the window well, was not
exposed. It is not clear whether there is a sub-soil footing drain at the perimeter of the
basement, as required by UPC1101.5, and IRC405.1. If there is a sub-soil drain in place, then it
will be acceptable to connect the window well area drain by gravity to the drain. If it becomes
necessary to install a new footing drain, it may be acceptable to install an electric sump pump to
discharge the water from the footing drain to an approved location, UPC1101.5.3.
4.All work shall be inspected by the city building inspector prior to cover.
Feel free to give me a call if you have any questions regarding this information.
