a. Existing sewer lateral elevations and slopes are not available through any as -built
records acquired. A label has been added indicating the SSCO near the house with
a rim and invert elevation. Without known as -built data the contractor will need to
locate and pothole the existing lateral to determine the invert elevation at the location
of the western SSC® prior to construction.
b. Rim and invert elevations have been added to the SDC®'s within the infiltration
galleries.
12. The impervious area summary table has been updated to match the updated site plan.
13. All of the paved surfaces are now shown to be asphalt.
14. The driveway width has been reduced to 24 feet wide.
