         a)   A vicinity map of appropriate scale and covering sufficient adjoining territory so as to clearly indicate nearby street patterns, major access streets, property lines, other adjacent properties in the subdivider's ownership, and other significant features which will have a bearing upon the proposed subdivision and its location and relationship to surrounding areas;
         b)   A preliminary soil investigation and geological reconnaissance report by a registered civil engineer, engineering geologist or geologist, specializing and recognized in soil mechanics and foundation engineering.

Maps shall also be provided in digital format as specified by the city.
   B.   Tentative Map Process.
      1.   A tentative map shall not be considered as having been filed unless and until it complies with all provisions of this title and the drawings, statements and other data required to accompany the tentative map have been submitted in a form acceptable to the advisory agency.
      2.   If the preliminary soils report indicates the presence of critically expansive soils or other soil problems, including seepage, which, if not corrected, would lead to structural defects, a soils investigation of each lot in the subdivision may be required by the public works director as a condition precedent to consideration of the tentative map. The soils investigation shall be done in the manner provided in the Subdivision Map Act.
      3.   In every subdivision for which a soil investigation has been required by the public works director, the council may approve the subdivision or portion thereof, notwithstanding evidence of critical soils problems. As a condition of the approval of the tentative map, the council shall order the withholding of the issuance of any building permit for development of those lots until the recommended corrective action, as determined by the director, is incorporated into the plans for the construction of each such structure.
      4.   A public hearing shall be held by the planning commission in accordance with section 18.07.010(A)(4) of this title.
