The proposed 48-inch storm sewer near Building C is within a few feet of the building. Please investigate whether or
not the waterline could be relocated farther south, thus allowing for the storm sewer to be moved at least 10-feet from
the building. See Sheet 6. This may require an easement within the railroad easement. If this is not possible, an
alternative would be to use water tight pipe like DIP, for the area in front of Building C.

Please provide an outfall for the sub -basin south of the railroad tracks. The parking lot drains to the east along the
