All U.S., state, county and other official benchmarks, monuments or triangular stations in or adjacent to the property shall be preserved in precise position.

      (1)   Storm water drainage shall not be permitted to combine with sanitary sewers, nor shall sanitary sewage be permitted in storm water sewers.
      (2)   Where lots cannot be connected with a public sewerage system, provisions must be made for sanitary sewerage facilities, consisting of a central treatment plant or individual disposal devices for each lot. This does not mean that the subdivider must provide such devices.
      (3)   Any subdivision or lot not provided with off-site water and off-site sewer facilities shall be subject to soil and percolation tests being made to determine whether or not the lot size proposed will meet minimum standards of health and sanitation. Such tests shall be made at the expense of the subdivider.
