    • Mechanical/Equipment Layout Plan with Equipment Schedule
    • Plumbing Plan with Fixture and Drain Size Schedule
  2. Sewer Elevations (USGS):
    The site plan should show proposed finish floor elevation, proposed invert of building drain where it exits the foundation, manhole inverts and the invert of the existing sanitary sewer at the proposed connection point.
  3. Materials:
