The Commission shall consider the tentative map as submitted by the subdivider together with the recommendations prepared by the City Engineer and the Director of Development Services. The Director of Development Services may, with a minimum of three working days prior to the Commission’s consideration of the project, require that all or any part of the boundaries and/or streets of a proposed subdivision be flagged at the site to facilitate any field review of the Commission. The Commission shall report, in writing, on the map of any subdivision submitted to it within 50 days after the tentative map has been filed, which report shall recommend to the Commission approval, conditional approval or disapproval of the tentative map. The 50-day time period shall commence after certification of the environmental impact report, adoption of a negative declaration, or a determination that the project is exempt from the requirements of Division 13 (commencing with Section 21000) of the Public Resources Code. The number, size and configuration of lots to be created and the alignment and width of streets and easements shall be clearly depicted upon the tentative map prior to recommendation of the Commission. Conditions to make the tentative map approvable, which involve modifications to lots in terms of number, size or configuration, or to streets in terms of alignment or width, may be set forth by the Commission for the guidance of the subdivider. However, when such conditions are substantial, the Commission may require that these changes be incorporated upon a revised tentative map and returned to the Director of Development Services who shall have the authority to determine on behalf of the Commission if the map is clearly in conformity with the conditions established by the Commission. The Director of Development Services may, at his discretion, require that the revised map be submitted to the Commission for further review in any instance where the map is not clearly in conformity with such conditions.
