INSPECTED (Green) - Lawful Occupancy Permitted is to be posted on any building or structure wherein no apparent structural hazard has been found. This placard is not intended to mean that there is no damage to the building or structure.
RESTRICTED USE (Yellow) - is to be posted on each building or structure that has been damaged wherein the damage has resulted in some form of restriction to the continued occupancy. The individual who posts this placard will note in general terms the type of damage encountered and will clearly and concisely note the restrictions on continued occupancy.
UNSAFE (Red) - Do Not Enter or Occupy is to be posted on each building or structure that has been damaged such that continued occupancy poses a threat to life safety. Buildings or structures posted with this placard shall not be entered under any circumstance except as authorized in writing by the Building Official, or their authorized representative. Safety assessment teams shall be authorized to enter these buildings at any time. This placard is not to be used or considered as a demolition order. The placard must note in general terms the type of damage encountered, the County Code section violated and the following text: County of Santa Cruz, 701 Ocean Street, 4th Floor, Santa Cruz, CA 95060, (831) 454-2260.
Once it has been attached to a building or structure, a placard is not to be removed, altered or covered until done so by an authorized representative of the Building Official.

Where tests indicate that soils at a pool site are non-expansive or have low expansion characteristics from the ground surface to the full depth of the pool, structural design may be based on an equivalent fluid pressure not less than 30 p.c.f.
In highly expansive soils having an expansion index of 91 to 130, pools shall be designed for not less than 60 p.c.f. equivalent fluid pressure.
In very highly expansive soils having an expansion index over 130, pool design shall be subject to special requirements based on a site investigation, soil testing, and engineering analysis by a registered civil engineer to determine appropriate design parameters for the site.
(3) 
Hydrostatic Uplift. In areas of anticipated high water table or moderate to highly expansive soil an approved hydrostatic relief system or device shall be installed.
(4) 
Thermal Protection for Plastic Piping. Between the inlet of pool water heating equipment and any plastic water piping connected thereto, a check valve shall be installed to prevent thermal damage to such piping due to backflow. When rapid or high-rate filters are employed a check valve may be omitted. Between the outlet of pool heating equipment and any plastic water piping connected thereto, not less than five feet of approved metal pipe shall be installed for the purpose of dissipating heat.
(K) 
Decks.

General. A deck shall be provided around below-grade swimming pools except when special engineering design is furnished which indicates that such deck is not necessary for the purpose of maintaining the structural integrity of the pool and/or for controlling surface water and moisture content in the soil adjacent to the pool. Decks shall not be required for spas and hot tubs.
(2) 
Deck Design and Construction. Required decks shall be constructed of concrete or other approved impervious material and shall be sloped to provide positive drainage away from the perimeter of the pool. Except as provided below, decks shall have a minimum width of four feet and shall be at least three and one-half inches in thickness. Reinforcement shall be No. 3 bars spaced not over 24 inches on center each way, or equivalent reinforcing.
Approved joints shall be provided in the deck at corners, at maximum 10-foot intervals, and wherever necessary in order to control cracking, to allow for differential movement, and to minimize damage to the deck from such movement should it occur.
Joints in decks and coping shall be made watertight with an approved permanent resilient sealant.
(3) 
Cutoff Walls. At the outer perimeter of pool decks a cutoff wall of approved material shall be installed below-grade to a depth of at least 15 inches so as to form a permanent and effective vertical moisture barrier.

Exception: A cutoff wall may be omitted when a deck at least six feet wide is installed.
(b) 
Exception: Decks less than four feet in width may be installed; provided, that the required cutoff wall is increased in depth beyond the minimum by an amount equal to the reduction in deck width.
(4) 
Pre-Saturation—Highly Expansive Soils. When the soil below a deck has an expansion index of 91 or greater it shall be saturated with water to a depth of at least 18 inches prior to installation of the deck.
(L) 
Drainage and Disposal.
(1) 
Surface Water. Surface water from pool decks shall be collected and conducted through noncorrosive devices to a street, storm drain, or other approved watercourse or disposal area.
(2) 
Wastewater. Pool wastewater shall be disposed of in accordance with the requirements of Environmental Health.
(3) 
Drywells.
