15.04.160 Safety Assessment Program (SAP) placards. Revised 12/19

The Safety Assessment Program (SAP) placards are hereby adopted and establish standard placards to be used to indicate the condition of a structure for continued occupancy. This section further authorizes the Building Official and his or her authorized representatives to post the appropriate placard at each entry point of a building or structure upon completion of a safety assessment.

A.    Application. The provisions of this section are applicable to all buildings and structures of all occupancies regulated by the City of San Carlos. The City Council may extend the provisions as necessary.

B.    Definitions. “Safety assessment” means a visual nondestructive examination of a building or structure for the purpose of determining the condition for continued occupancy.

C.    Placards. The following are general descriptions of the official City of San Carlos placards to be used to designate the condition for continued occupancy for buildings or structures. The actual placards shall be in a form approved by the City Manager and substantially similar in substance to the following:

1.    “INSPECTED – 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. This placard shall be green.

2.    “RESTRICTED USE” 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 for continued occupancy. This placard shall be yellow.

3.    “UNSAFE – 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 circumstances except as authorized in writing by the Building Official or his or her authorized representative. Safety assessment teams shall be authorized to enter buildings posted with a red placard at any time. This placard shall not be used or considered as a demolition order. The individual who posts a red placard shall note in general terms the type of damage encountered. This placard shall be red.

The name of the jurisdiction, its address, and phone number shall be included on each placard posted.

Once a placard has been attached to a building or structure, it shall not be removed, altered, or covered except by an authorized representative of the Building Official, or upon written notification by the Building Official.

It shall be unlawful for any person, firm, or corporation to alter, remove, cover, or deface a posted placard unless authorized by this section. (Ord. 1553 § 2 (Exh. A (part)), 2019: Ord. 1513 § 1 (Exh. A (part)), 2016: Ord. 1470 § 1 (Exh. A (part)), 2013: Ord. 1428 § 2 (part), 2010)

15.04.170 Findings. Revised 12/19

The following findings have been made:

A.    Geologic. The City of San Carlos is located near a very active seismic area, seismic zone E (previously known as seismic zone 4). The entire City is two to seven kilometers from the San Andreas Fault, a major active fault in California.

There are five major soils types in the City from the bay to the hillsides. There is existing fill overlying unconsolidated Holocene Bay mud deposits. There are unconsolidated Holocene fine- to coarse-grained alluvial fan and basin deposits with a water table equal to or less than ten feet. There are unconsolidated Holocene fine- to coarse-grained alluvial fan deposits with a water table equal to or greater than ten feet. There are weak consolidated Pleistocene fine- to coarse-grained alluvial fan and basin deposits. There are colluvial and landslide deposits locally overlying sandstone and bedrock units.

There are high flooding hazards in two of the five soils types and moderate flooding hazards in two of the five. There is high ground settlement potential in the area along the bay. There is high potential for seismically induced ground failure in the same area and moderate potential in the adjacent area.

There is a high potential for seismically induced ground shaking in all areas in the City. There is a high potential for liquefaction in the area adjacent to the bay and moderate potential in the adjacent area. There is moderate potential for erosion and slope instability/landslides in approximately fifty percent of the City. Expansive soils or bedrock varies in significance in over two-thirds of the entire City.

These actions can cause great damage to structures in or on the ground. Gypsum wallboard and exterior Portland cement plaster have performed poorly during recent California seismic events. Cyclic seismic action testing has proven the limited seismic resistance of these materials.

Potential Geologic and Seismic Hazards Map.

Based upon these geologic findings, the City Council hereby adopts and designates the Harlan Tait Associates “Potential Geologic and Seismic Hazards Map, City of San Carlos, California” dated February 22, 1996, and Hazard Zone A and Hazard Zone B handouts, as minimum criteria to determine when a geotechnical investigation report (soils report) is required for development within the City.

B.    Climatic. The local climate is characterized by markedly delineated rainy and dry seasons, which tend to maximize the expansive characteristics of soil.

C.    Topography. San Carlos topography includes mountain and foothill areas. The ground elevation rises over nine hundred feet in less than one mile in much of the City resulting in large areas of unstable, steep slopes. Upgraded structural provisions are required to construct housing on these unpredictable, unstable steep slopes. Upgraded automatic sprinkler provisions are required due to approximately one-quarter of residential properties located in very high fire hazard severity zone.

D.    The City Council hereby declares that it would have passed the ordinance codified in this chapter sentence by sentence, paragraph by paragraph and section by section, and does hereby declare that any provisions in this chapter are severable and, if for any reason any sentence, paragraph or section of this chapter shall be held invalid, such decision shall not affect the validity of the remaining parts of this chapter.

E.    The ordinance codified in this chapter shall be published and posted according to law and shall take effect and be in force from and after thirty days after its passage and adoption.
