14.50(11).120 Permissible Site Coverage.
(1) Except as provided for in this section, in the Very-High Density Restricted Area PRO zone all building and structures shall not cover an area of more than sixty percent (60%) of the site upon which they are placed.
(2) A subgrade structure which would otherwise be subject to the provisions of Chapter 14.06, Provo City Code, may extend three (3) feet above natural grade so long as such structure:
(a) does not exceed one hundred (100) feet in length;
(b) is approved only where the terrain of the project site does not permit the subgrade structure to be located entirely below grade; and
(c) is finished with architectural materials which are consistent and compatible with the architectural finish of the associated above-grade building(s) within the project.
(3) The placement of a vertical face of a subgrade structure exceeding two and one-half (2 1/2) feet above natural grade and not covered with a minimum of six (6) inches of soil to support landscape vegetation or not otherwise meeting the definition of a subgrade structure as set forth in Chapter 14.06 may be allowed within a required front or street side yard so long as:
(a) the City Engineer determines that the increase in height and the location of an exposed subgrade structure does not create a safety hazard due to interference with sight distance for drivers or pedestrians or due to violations of clear vision standards; and
(b) the visual and spatial impacts to pedestrians on an adjoining public sidewalk or to adjoining properties can be reasonably mitigated through landscaping or other design elements approved as part of a project plan.
