Atascadero City Council
Staff Report - Community Development Department


               Title 8 Building Regulations Update and
  2004 California Electrical Code Adoption with Minor Modifications



RECOMMENDATION:
Council introduce for first reading, by title only, Draft Ordinance A, approving
amendments to Title 8 of the Atascadero Municipal Code pertaining to Building
Regulations.


DISCUSSION:
Background: Title 8 is the local building regulations (Local Building Code). Every three
years California adopts the State Codes, and gives local jurisdictions an opportunity to
modify them, or adopt them in their entirety. The State has adopted a new California
Electrical Code, with an effective date of August 1, 2005. The City’s only proposed
modification to this portion of the State Codes is the authority to disconnect in the event
of an emergency. This is consistent with our current electrical code modification.

Building staff has also made some slight changes to the Building Code in Title 8, in
order to clarify and/or correct minor issues. These changes include a change to the soils
report requirements for swimming pools, an exception to construction requirements for
deck projections over descending slopes, and an additional chapter to provide
regulations after a declared natural or man-made disaster.

Summary: Due to the adoption of the 2004 California Electrical Code, and the
opportunity to modify this code with local amendments, the Division of Building Services
proposes these modifications to the City’s Building Regulations. The Codes and
amendments proposed, will improve public safety by throughout our community.

The significant modification to the Electrical Code includes:

          o Electrical Code modified to authorize disconnection of electrical service in
            case of emergency, with no additional changes
Minor changes to the Building Code include:

          o Change the requirement for soils reports for swimming pools from 10%
            slope to 30% slope
          o Provide an exception for deck projections over descending slopes to
            eliminate the requirement for enclosing the unused underfloor space on
            decks when at least 50% of the perimeter is a minimum of 6 feet above
            grade

An additional chapter has been added to Title 8 to include:

          o Placement of standard placards after a natural or man-made disaster
          o Establishment of standards and regulations for the repair and
            reconstruction of structures damaged as a result of a natural or man-made
            disaster

Analysis: Currently Title 8 requires soils reports for swimming pools constructed on
slopes greater than 10%. This requirement has been changed to 30% to be consistent
with the requirements of the 2001 California Building Code. . Construction in Designated
Fire Severity Zones is mandated by the adoption of the Urban Wildland Interface Code,
and is consistent with Title 4-7. There has been some confusion over construction
requirements on appendages, such as decks, projecting over descending slopes. We
have provided an exception to Section 8-3.106.F.6 and 8-3.106.G.6 to eliminate the
requirement to enclose the underfloor area on decks when more than 50% of the
perimeter is at least 6 feet above grade. The placement of placards and repair and
reconstruction requirements after a natural or man-made disaster will provide additional
security in emergency situations.

Conclusion: The Title 8 update is a routine process provided by the State of California
when new codes are adopted. Building Services staff has taken this opportunity to
clarify and update Building and Post Disaster regulations. This Ordinance will take the
guesswork out of many of the City’s regulations.

FISCAL IMPACT:
None

ALTERNATIVES:
1. The City Council may approve the code amendment subject to minor changes and
   additions. The Council’s motion to approve needs to include any changes.
   Significant changes should be referred back to staff for additional analysis.

2. The Council may continue the hearing and refer the item back to staff for additional
   information or analysis. Direction should be given to staff and the applicant on
   required information.

                     DRAFT ORDINANCE A
             AN ORDINANCE OF THE CITY COUNCIL OF
          ATASCADERO, CALIFORNIA, AMENDING TITLE 8
            (BUILDING REGULATIONS) OF THE CITY OF
        ATASCADERO MUNICIPAL CODE IN ITS ENTIRETY AND
           ADOPTING CERTAIN UNIFORM MODEL CODES
           RELATING TO BUILDING CONSTRUCTION AND
                        MAINTENANCE

        WHEREAS, Government Code Section 50022, et seq. and California Health & Safety
Code Section 17922 empower the City of Atascadero ("City") to adopt by reference the
California Building Standards Code (the “California Building Standards Code”) as provided in
Titles 24 and 25 of the California Code of Regulations and other codes, including, without
limitation, the Uniform Housing Code, Uniform Code for the Abatement of Dangerous Buildings
and Uniform Administrative Code; and

       WHEREAS, the California Building Standards Commission ("Commission") recently
adopted new amendments to the California Building Standards Code; and

        WHEREAS, California Health & Safety Code, Section 17958.5 authorizes cities to
modify the California Building Standards Code by adopting more restrictive standards and
modifications if such standards and modifications are accompanied by express findings that they
are reasonably necessary because of local climatic, geological or topographical conditions; and

        WHEREAS, the City Council of the City of Atascadero ("City Council") finds that local
climatic, geological or topographical conditions exist within the City, which include, but are not
limited to, the following:


       FINDING 1

       That the City of Atascadero is situated at the base of a watershed of the Santa Lucia
       Mountains and that flooding of Atascadero Creek, Graves Creek, and Salinas River
       results in conditions rendering fire department vehicular traffic unduly burdensome or
       impossible as witnessed in major floods that occurred in 1952, 1961, 1969, 1973, 1978,
       1982, and 1995. Furthermore, flood conditions described above create the potential for
       overcoming the ability of the fire department to aid or assist in fire control, evacuations,
       rescues and other emergency task demands inherent in such situations. The resulting
       overburdening of fire department personnel may cause a substantial or total lack of
       protection against fire for the buildings and structures located in the City of Atascadero.
       The afore-described conditions support the imposition of fire protection requirements
       greater than those set forth in the California State Building Standards Code and, in
       particular, support the imposition of greater requirements than set forth in Sections
       601.5.9, 705, 904.2.2, and 1503, and Appendix Sections 3104.2, 3106, and 3107.2 of the
       1998 California Building Code, Article 230-70 of the 1998 California Electrical Code,
and Sections 902.2.4.3, 902.3.4, 903.3, 1001.9, 1002.1, 1003.2, 1003.3.1, 1006.1,
1007.3.3.6.1, 1102.3.1, 1102.4.1, 5202.3.6, 7802.3, 7902.2.2.1, and 8204.2 and Appendix
II-F Sections 1 and 4.3 of the 2001 California Fire Code.

FINDING 2

That the City of Atascadero is situated near three major faults each capable of generating
earthquakes with a magnitude of 7.5. These are the San Andreas to the east of the City,
the Nacimiento-Rinconada that crosses Hwy 101 north of the City then parallels the City
to the east, and the Hosgri to the South West. Other faults of importance are the Huasna
and West Huasna to the Southeast of the City, the San Simeon to the Northwest. In as
much as these faults are included as major California earthquake faults, which are subject
to becoming active at any time, the City Atascadero is particularly vulnerable to
devastation should such an earthquake occur. The potential effects include isolating the
City of Atascadero from the North and South due to the potential for collapsing of
freeway overpasses or a slide on both the Cuesta and Ontario Grades and the potential for
horizontal or vertical movement of the Edna fault rendering surface travel across the
southern extremities of the city unduly burdensome or impossible. Additional potential
situations inherent in such an occurrence include broken natural-gas mains causing
structure and other fires, leakage of hazardous materials, the need for rescues from
collapsed structures, and the rendering of first aid and other medical attention to large
numbers of people. The protection of human life and the preservation of property in the
event of such an occurrence support the imposition of fire protection requirements greater
than those set forth in the California State Building Standards Code and in particular
support the imposition of greater requirements than set forth in Sections 601.5.9, 705,
904.2.2, and 1503 of the 1998 California Building Code, Article 230-70 of the 2001
California Electrical Code, and Sections 902.2.4.3, 902.3.4, 903.3, 1001.9, 1002.1,
1003.2, 1003.3.1, 1006.1. 1007.3.3.6.1, 1102.3.1. 1102.4.1. 5202.3.6, 7802.3, 7902.2.2.1,
and 8204.2 and Appendix II-F Sections 1 and 4.3 of the 2001 California Fire Code.

FINDING 3

That the central commercial area in the City of Atascadero consists of mixed conditions
that create the potential for possible conflagration, including congested streets during the
business day, numerous older buildings without adequate internal fire-resistance, and
contemporary low-rise buildings. Significant spread of fire in said area will actually
exceed the fire suppression capabilities of regional firefighting personnel. The continued
development of the Atascadero commercial area and the current and potential
development of high-rise buildings pose a substantial threat of fire to human life, public
safety, and the preservation of property and support the imposition of fire protection
requirements greater than those set forth in the California State Building Standards Code,
and in particular, support the imposition of greater requirements than set forth in Sections
601.5.9, 705, 904.2.2, and 1503 of the 2001 California Building Code, Article 230-70 of
the 1998 California Electrical Code, and Sections 902.2.4.3, 902.3.4, 903.3,1001.9,
1002.1,1003.2, 1003.3.1, 1006.1.1007.3.3.6.1, 1102.3.1, 1102.4.1, 5202.3.6, 7802.3,
7902.2.2.1, and 8204.2 and Appendix II-F Sections 1 and 4.3 of the 2001California Fire
Code.

FINDING 4
That the City of Atascadero is bisected by a major freeway (Hwy 101), traversing in the
north/south direction and a major highway (Hwy 41) traversing in an east/west direction.
The City is also transected by a mainline railroad that traverses in the north/south
direction. It is a frequent occurrence for the aforementioned highways and railway to
support the transportation of hazardous materials. The potential for release or threatened
release of a hazardous material along one of these routes is highly probable given the
volume transported daily. Incidents of this nature will normally require all available
emergency response personnel to prevent injury and loss of life, and to prevent as far as
practicable, property losses. Emergency personnel responding to said incidents may be
unduly impeded and delayed in accomplishing an emergency response as a result of this
situation, with the potential result of undue and unnecessary risk to the protection of life
and public safety, particularly in those buildings or structures without the protection of
automatic fire sprinklers. The above-described problems support the imposition of fire
protection requirements greater than those set forth in the California State Building
Standards Code, and in particular support the imposition of greater requirements than set
forth in Sections 601.5.9, 705,904.2.2, and 1503 of the 2001 California Building Code,
Article 230-70 of the 1998 California Electrical Code, and Sections 902.2.4.3, 902.3.4,
903.3, 1001.9, 1002.1, 1003.2, 1003.3.1, 1006.1, 1007.3.3.6.1, 1102.3.1, 1102.4.1,

FINDING 5

That seasonal climatic conditions during the late summer and fall create numerous
serious difficulties in the control and protection against fire situations in the City of
Atascadero. The hot, dry weather in combination with Santa Ana winds frequently
results in wildland fires in the brush-covered slopes on the Santa Lucia Mountains and
several areas surrounding. The aforementioned areas completely surround the City.
When a fire occurs in said areas, such as occurred in 1994, the Highway 41 fire burned
for several days and entered the City, the entirety of local fire department personnel is
required to control, monitor, fight and protect against such fire situations in an effort to
protect life and preserve property and watershed land. The same climatic conditions may
result in the concurrent occurrence of one or more fires in the more populated areas of the
City without adequate fire department personnel to protect against and control such a
situation. Therefore, the above-described findings support the imposition of fire-
protection requirements greater than those set forth in the California State Building
Standards Code, and in particular support the imposition of greater requirements than set
forth in Sections 601.5.9, 705, 904.2.2, and 1503 of the 2001 California Building Code,
Article 230-70 of the 2001 California Electrical Code, and Sections 902.2.4.3, 902.3.4,
903.3, 1001.9, 1002.1, 1003.2, 1003.3.1, 1006.1, 1007.3.3.6.1, 1102.3.1, 1102.4.1,
5202.3.6, 7802.3, 7902.2.2.1, and 8204.2 and Appendix II-F Sections 1 and 4.3 of the
2001 California Fire Code.



FINDING 6

That for the most part, the soils in the City of Atascadero are medium to highly expansive
in nature, and such soils may cause damage to foundations, structures and underground
utilities if not properly mitigated through known construction techniques. Furthermore, a
significant part of the City lies on hills and rolling topography subject to earth slides and
movements and present problems to developments constructed in such areas due to
       surface water drainage and disposal. The above-described conditions support the
       imposition of requirements greater than those set forth in the California State Building
       Standards Code and, in particular, support the imposition of greater requirements than
       those set forth in Sections 1804.7, 1806.1, and 1900.4.4, Table 18-I-C, 3102.7.2, and
       Appendix Sections 421, 3305, 3306, 3307, 3308, 3309.3, 3309.4, 3309.8, 3309.10,
       3309.11, 3311, 3316.1, and 3318.3 of the 2001 California Building Code and Section
       315.4 of the 2001 California Plumbing Code.

       FINDING 7

       That the more-restrictive modifications requiring automatic fire-sprinkler systems in
       buildings evidenced by the afore-described findings allow a trade-off for, and reduction
       of, other less effective fire-resistive components of a building support the acceptance of
       requirements lesser than those set forth in the California State Building Standards Code
       and, in particular, support the imposition of lesser requirements than those set forth in
       Section 709.4.1 of the 2001 California Building Code and Sections 902.2.1 and 903.2 of
       the California Fire Code.

       WHEREAS, based upon the recommendations of the Building Official and Fire Chief,
the City Council finds that the proposed amendments to the California Building Standards Code
("amendments") are more restrictive than the standards adopted by the California Building
Standards Commission, would decrease the potential incidence of property damage, injury and
death due to fires and earthquakes, and are reasonable and necessary to mitigate the
aforementioned local climatic, geologic or topographical conditions.

       WHEREAS, the City Council finds that each of the local amendments to the California
Building Standards Code are supported by the local climatic, geologic and/or topographic
conditions described herein.

      Title 8 of the City of Atascadero Municipal Code is hereby amended in its entirety to read
      as follows:

CHAPTER 1              ADMINISTRATIVE

8-1.101      Title

                       A. This Title shall be known as the City of Atascadero Building Code,
                           Title 8 of the Atascadero Municipal Code.

8-1.102      Purpose

                       A. The City Council expressly finds that the purpose of this Code is to
                          provide minimum standards to safeguard life, limb, health, property
                          and public welfare by regulating and controlling the design,
                          construction, quality of materials, use and occupancy, location and
                          maintenance of buildings and structures within the City of
                          Atascadero.

                           such local, police, sanitary and other regulations as are not in
                           conflict with the general laws of the State. It is further adopted
                           pursuant to the applicable provisions of the State Housing Laws
                           (Health and Safety Code Section 17910 et seq., and particularly
                           Sections 17922 and 17958 thereof) and applicable rules and
                           regulations promulgated pursuant thereto as Title 24 and 25 of the

                 structures; and buildings and structures owned and constructed by a Federal,
                 State, or other agency whose authority preempts that of City government. It
                 shall be unlawful for any person, firm, or corporation to erect, construct,
                 enlarge, alter, repair, move, improve, remove, convert, demolish, equip, use,
                 occupy, or maintain any building or structure in the County, or cause the same
                 to be done, contrary to, or in violation of, any of the provisions in this Code,

                    A. Permits Required. No person, firm, or corporation shall erect,
                        construct, enlarge, alter, repair, move, improve, remove, convert or
                        demolish any building or structure regulated by this Code, or cause
                        the same to be done, without first obtaining the necessary permits
                        for each separate building or structure from the Building Official.
        B. Permits Required / Grading or Waste Disposal Not Separate.

              1.   Grading and or waste disposal system permits for residential

                   without the specific approval of the Building Official and City

              2. Grading permits are required for earth movement of over 50
                  cubic yards and/or for cuts or fills in excess of 3 feet.

         C.    Expiration of Permit.      Section 106.4.4 is replaced with the
following:

              1.   Every permit issued by the building official under the
                   provisions of this code shall expire by limitation and become
                   null and void if the building or work authorized by such permit
                   is not commenced within 180 days from the date of issuance of
                   such permit, or if the building or work authorized by such
                   permit is suspended or abandoned at any time after the work is
                   commenced for a period of 180 days.

              2.   Failure to request and receive a recorded inspection by the
                   Administrative Authority within the 180-day period constitutes
                   a condition of suspension or abandonment.

              3.   Before such abandoned or suspended work can be
                   recommenced, a new permit shall be obtained to do so, and the
                   fee therefore shall be one half the amount required for a new
                   permit for such work, but in no case less than $84.00, provided
                   no changes have been made or will be made in the original
                   plans and specifications for such work, and provided further
                   that such suspension or abandonment has not exceeded one
                   year. In order to renew action on a permit after expiration, the
                   permittee shall pay a new full permit fee.

              4.   Any permittee holding an unexpired permit may apply for an
                   extension of the time within which work may commence under
                   that permit when the permittee is unable to commence work
                   within the time required by this section for good and
                   satisfactory reasons. The building official may extend the time
                   for action by the permittee for a period not exceeding 180 days
                   on written request by the permittee showing that circumstances
                   beyond the control of the permittee have prevented action from
                   being taken. No permit shall be extended more than once.

        D.     Expiration of Plan Review. Section 106.4.4 is replaced with the
                  following:

              Applications for which no permit is issued within 180 days
              following date of notification of approval/ready for issuance by the
              Building Division, or applications within 180 days following date of
                       notification of permit corrections to be picked up or returned, shall
                       expire by limitation, and plans and other data submitted for review
                       may thereafter be returned to the applicant or destroyed by the
                       building official. In order to renew action on an application after
                       expiration, the applicant shall resubmit plans and pay a new plan
                       review fee. No extension is allowed except by written appeal to the
                       Building Official. No application shall be extended more than once.

                  E.    Permit Fees. Section 107.2 is replaced with the following:

                       Permit fees shall be established by City Council resolution as may be
                       necessary from time to time. The value to be used in computing the
                       building permit and building permit plan review fees shall be the
                       total value of all construction work for which the permit is issued as
                       well as all finish work, painting, roofing, electrical, plumbing,
                       heating, air conditions, elevators, site work, fire-extinguishing
                       systems and any other permanent equipment, The regional modifier
                       shall be 1.0.

                  F. Emergency Permits. Emergency permits may be issued by the
                     Building Official for any area of work regulated by this Code when
                     it is determined that the work is of an emergency nature and failure
                     to perform the work may be detrimental to the health, safety, or
                     welfare of the occupants, public, or the environment. Applications
                     for emergency permits shall be filed no later than 10 days from the
                     date of commencement of emergency work. An emergency permit

             During the course of exercising the duties delegated to the Building Official in
             Section 8-2.102 this Code, and when, in the opinion of the Building Official,
             there exists a reason to believe that a violation of this Code or due cause exists
             to inspect a property, the Building Official, or designee, is hereby authorized
             to enter such property or premises at any reasonable times and to inspect and

             credentials to the occupant and request entry, explaining his/her reasons
             therefore. If such entry is refused or cannot be obtained because the owner or
             person having charge or control of the property cannot be located after due
             diligence, the Building Official shall seek judicial authorization for entry
             pursuant to an inspection warrant in accordance with the procedures set forth
             in the California Code of Civil Procedure sections 1822.50-1822.57.
             Notwithstanding the foregoing, if the Building Official or designee has
             reasonable cause to believe that there exists an unsafe, substandard, or
             dangerous condition within the building or premises as to require immediate
             inspection to safeguard the public health or safety, he/she shall have the right
             to immediately enter and inspect such property and may use any reasonable
             means required to secure such entry and make such inspection, whether such
             property is occupied or unoccupied and whether or not permission has been
             sought or obtained."

                   to pay to the City of Atascadero all costs incurred by the City of
                    Atascadero in obtaining abatement or compliance that is attributable to

                   with the requirements of this Code, the State Housing Laws, or any
                   other code adopted herein, the Building Official may cause a Notice of
                   Noncompliance to be recorded with the County Recorder and shall
                   notify the owner of the property of such action. The Notice of
                   Noncompliance shall describe the property, shall set forth the non-
                   complying conditions, and shall state that the owner of such property
                   has been duly notified. The Building Official shall record a notice of
                   release of the Notice of Noncompliance with the County Recorder

                   substandard under the provisions of the Uniform Housing Code, the
                   Uniform Code for the Abatement of Dangerous Buildings, or the State
                   Housing Law, or that are otherwise dangerous to human life, or that
                   constitute a hazard to health, safety or public welfare by reason of
                   inadequate maintenance, dilapidation, damage, obsolescence, or
                   abandonment as specified in this Code, or any other effective

      and shall be protected from backflow of sewage by installing an
      approved backwater valve. Each such backwater valve shall be
      installed only in that branch or section of the drainage system that
      receives the discharge from fixtures located less than one (1) foot
      above the nearest upstream manhole cover.

B. Private Sewage Disposal Systems. The design, installation operation and
   maintenance of private sewage disposal systems shall be in conformance
   with Appendix K of the Uniform Plumbing Code and with standards
   specified in this section. Where specific standards are not provided within
   this section or where the Administrative Authority determines that higher
   requirements are necessary to maintain a safe and sanitary condition, the
   "Water Quality Control Plan, Central Coast Basin" (adopted by the
   Regional Water Quality Control Board of the Central Coast Region) or
   other recognized industry standards may be used as a guideline by the
   Administrative Authority.

C. Percolation Test. An on-site investigation shall be made by a registered
   engineer competent in sanitary engineering in order to determine the
   suitability of a particular site for a private sewage disposal system and to
   provide the data necessary to design a private sewage disposal system. A
   percolation test shall be required prior to issuance of a permit for all new
   or enlarged private sewage disposal systems.

D. Test Procedures. The following percolation test procedure shall be used
   in performing percolation tests, except that other accepted test procedures
   may be used when approved by the Administrative Authority:

   1. Number and Location of Test Holes. A minimum of three separate
      test holes spaced uniformly through and located in the immediate
      vicinity of the proposed leach field site are to be made.
2. Type of Test Holes. The test hole shall have horizontal dimensions
   between four (4) and twelve (12) inches and vertical sides to the depth
   of the absorption trench.

3. Preparation of Test Holes. Smeared soil surfaces shall be removed
   from the sides and bottom of the test hole to provide a natural soil
   interface. All loose material shall be removed from the test hole. Two
   (2) inches of coarse sand or fine gravel shall be added to the test hole
   to protect the bottom from scouring and sediment.

4. Soil Saturation and Swelling. The test hole is to be carefully filled to
   a depth of one (1) foot above the gravel or sand with clear water,
   which is to be kept in the hole for at least four (4) hours but preferably
   overnight. This step may be omitted in sandy soils containing little or
   no clay.

5. Measurement of Percolation Rate. The percolation rate shall be
   determined twenty-four (24) hours after water is first added to the test
   holes; except, in sandy soils containing little or no clay, the percolation
   rate shall be determined after the water from one (1) filling, of the test
   hole has completely seeped away.

     (i)    If water remains in the test hole after the overnight swelling
            period, adjust the depth to approximately six (6) inches over
            the gravel or sand and, from a fixed referenced point, measure
            the drop in water level over a thirty (30) minute period to
            calculate the percolation rate.

     (ii)   If no water remains in the test hole after the overnight swelling
            period, add clear water to bring the depth of water in the test
            hole to approximately six (6) inches over the gravel or sand.
            From a fixed reference point, measure the drop in water level at
            approximately thirty (30) minute intervals over four (4) hours
            refilling six (6) inches over the gravel or sand as necessary.
            The drop that occurs during the final thirty (30) minute period
            is used to calculate the percolation rate. The drops during prior
            periods provide information for possible modification of the
            test procedure to suit local conditions.

     (iii) In sandy soils (or in other soils in which the first six (6) inches
           of water seeps away in less than thirty (30) minutes after the
           overnight swelling period), the time interval between
           measurements shall be taken as ten (10) minutes and the test
           shall run for one (1) hour with the drop during the final ten (10)
           minutes being used to calculate the percolation rate.

6. Deep Boring. A soil boring, to a minimum depth of ten (10) feet
   below the bottom of the absorption trench or pit, shall be made in
   order to determine the presence of impermeable bedrock and/or
   ground water.
7. General Design Standards. The following standards shall be used in
   the design of new or enlarged private sewage disposal systems where
   the percolation rate does not exceed one hundred twenty (120) minutes
   per inch.

     (i)    Determination of Size of Absorption Area. The absorption
            area, measured in lineal feet of absorption trench, shall be
            calculated as set forth in this section. Tables 4-1 (Absorption
            Area Requirements) and 4-2 (Standard Trench Adjustment
            Factors), included in this chapter, shall be referred to as
            necessary. (absorption area per bedroom.) × (no. of bedrooms.)
            × adjustment factor

     (ii)   Location of Private Sewage Disposal Systems. The minimum
            distance between components of a private sewage disposal
            system and other site features shall be as set forth in Table 4-3
            (Horizontal Distance Separation) and Table 4-4 (Vertical
            Distance Separation). Where physical limitations on a site
            preclude conformance with distance separation requirements,
            the Administrative Authority may approve a lesser separation
            when the design is prepared by a registered engineer competent
            in sanitary engineering and when adequate substantiating data
            is submitted with the design. The Administrative Authority
            shall not approve a separation less than that set forth in the
            "Water Quality Control Plan--Central Coast Region" unless the
            Regional Water Quality Control Board or its designated
            representatives have previously approved the design.

8. Additional Standards:

     (i)    Existing legal building sites that are served by an individual
            on-site well may be approved for a private sewage disposal
            system only if the site meets lot size standards for private
            sewage disposal systems.

     (ii)   Private sewage disposal systems proposed to be installed on
            slopes of twenty percent (20%) or more shall be designed by
            and have their installation inspected and certified by a
            registered civil engineer. The design shall minimize grading
            disruption associated with access for installation and
            maintenance. Such systems shall be prohibited on slopes of
            thirty percent (30%) or more, unless approved by both the
            Administrative Authority and the Regional Water Quality
            Control Board.

     (iii) When the percolation rates is more then thirty (30)
           minutes/inch, a private sewage disposal system shall be
           designed, inspected, and certified to work by a registered civil
           engineer.
     (iv) When the percolation rates exceeds one hundred twenty (120)
          minutes/inch, a private sewage disposal system, using solely
          dependent upon soil absorption, shall not be allowed.

     (v)    The design of private sewage disposal systems shall
            incorporate an approved filtering device to remove solids from
            effluent at the outlet of septic tanks.

     (vi) When the percolation rate exceeds thirty (30) minutes/inch, a
          private sewage disposal system using a seepage pit shall not be
          allowed.

     (vii) Expansion area shall be provided on all building sites, shall be
           identified on all plans submitted for private sewage disposal
           systems, and shall remain available for system expansion. If
           areas reserved for system expansion are not accessible for
           future installation, then the expansion area shall be installed
           with the original system.

     (viii) Inspection risers with four (4) inches minimum diameter shall
            be installed at the ends of each absorption trench or bed.

     (ix) Septic tank manholes more than twenty-four (24) inches below
          grade, valves, distribution boxes, and pumps shall be
          permanently accessible to the surface in a manner acceptable to
          the Building Official.

9. Special Design Standards. The following standards shall be used in
   the design of new or enlarged private sewage disposal systems where
   the percolation rate exceeds sixty (60) minutes per inch. Designs for
   alternate types of private sewage disposal systems shall be by a
   registered civil engineer and may be approved by the Administrative
   Authority when the design engineer submits adequate substantiating
   data with the design.

     (i)    Determination of Size of Disposal Field. The size of the
            disposal field shall be determined by the design engineer using
            methods of accepted engineering practice including manuals
            and documents specified in this chapter or as otherwise
            approved by the Administrative Authority.

     (ii)   Location of Private Sewage Disposal System. The minimum
            distance between components of a private sewage disposal
            system and other site features shall be as set forth in Table 4-3
            (Horizontal Distance Separation) and Table 4-4 (Vertical
            Distance Separation) using the column entitled "Leach Field or
            Seepage Bed."

     (iii) When private sewage disposal systems are designed pursuant
           to this section, the design engineer shall provide the owner
             with information on the location, design operation and
             maintenance of the private sewage disposal system.

     (iv) Existing legal building sites that are served by an individual
          on-site well may be approved for a private sewage disposal
          system only if the site is one acre or larger in size and meets
          other regulations and requirements regarding distance
          separation.

     (v)     Expansion area shall be provided on all building sites.

10. Replacement of Existing Private Sewage Disposal System. Where
    an existing private sewage disposal system has failed, the replacement
    system shall be designed in conformance with this chapter and shall be
    designed, inspected and certified to work by a registered civil
    engineer. In the event that the replacement system cannot be designed
    to conform with this chapter, the Administrative Authority may
    approve a system designed to lesser standards when it is designed,
    inspected and certified to work by a registered civil engineer.

     (i)     A private sewage disposal system shall not be replaced by
             another system if sewers are available.

     (ii)    The Administrative Authority shall not approve a replacement
             system that does not conform with prohibitions set forth in the
             "Water Quality Control Plan--Central Coast Basin," unless the
             Regional Water Quality Control Board or its designed
             representative has previously approved the design. The
             Administrative Authority may authorize a temporary means of
             sewage disposal pending such approval. (Ord. 360 § 3 (part),
             1999)

CHAPTER 10         UNREINFORCED MASONRY

8-10.101    Unreinforced Masonry Buildings

               A. Purpose. The purpose of this chapter is to promote public safety and
                  welfare by reducing the risk of death or injury that may result from the
                 effects of earthquakes on unreinforced masonry bearing wall buildings.
                 Such buildings have been widely recognized as posing a threat to life
                 because of a history of poor performance, i.e. partial or complete collapse,
                 during moderate to strong earthquakes.

              B. Provisions. The provisions of this chapter are intended as minimum
                 standards for structural seismic resistance established primarily to reduce
                 the risk of life loss or injury. Compliance with these standards will not
                 necessarily prevent loss of life or injury or prevent earthquake damage to
                 rehabilitated buildings. This chapter does not require alteration of existing
                 electrical, plumbing, mechanical or fire safety systems (unless they
                 constitute a hazard to life or property).

              C. This chapter provides systematic procedures and standards for
                 identification and classification of unreinforced masonry bearing wall
                 buildings based on their present use. Priorities, time periods and standards
                 are also established under which these buildings are required to be
                 structurally analyzed and anchored. Where the analysis finds deficiencies,
                 this chapter requires the buildings to be strengthened or demolished.

                 Qualified Historical Buildings shall comply with the State Historical
                 Building Code (SHBC) established under Part 8, Title 24 of the California
                 Administrative Code. (Ord. 360 § 2 (part), 1999; Ord. 226 § 1 (part), Exh.
                 A (part), 1991)

8-10.102   Scope. The provisions of this chapter shall apply to all unreinforced masonry
           buildings.

              A. This chapter shall not apply to detached one- or two-family dwellings and
                 detached apartment houses containing less than five dwelling units and
                 used solely for residential purposes.

              B. This chapter shall not apply to warehouses and similar buildings used for
                 emergency services or supplies. (Warehouses that have been converted to
                 retail, office, commercial, or residential occupancies are not exempt.)

              C. This chapter shall not apply to buildings owned by the Federal or State
                 Government. (Buildings owned by local jurisdictions are not exempt.)

              All conforming and legal nonconforming buildings that are required to be
                 strengthened by alteration as a result of this chapter shall not be required
                 to comply with current site improvement standards of the City zoning
                 ordinance, including parking and landscaping.

              In the event a building owner does not agree with zoning or signage
                 conditions, he or she may seek relief through appeal to the Planning
                 Commission. (Ord. 360 § 2 (part), 1999; Ord. 226 § 1 (part), Exh. A
                 (part), 1991)

8-10.106      Administration.
A. Service of Order. The Building Official shall issue an order, as provided
   in subsection (b) of this section, to the owner of each building within the
   scope of this chapter within sixty (60) days from the effective date of these
   regulations.

B. Contents of Order. The order shall be in writing and shall be served
   either personally or by certified or registered mail upon the owner as
   shown on the last equalized assessment, and upon the person, if any, in
   apparent charge or control of the building. The order shall specify that the
   building has been determined by the Building Official to be within the
   scope of this chapter and, therefore, is required to meet the minimum,
   seismic standards of this chapter. The order shall specify the rating
   classification of the building and shall be accompanied by a copy of
   Section 8-10.105 of this chapter, which sets forth the owner's alternatives
   and time limits for compliance.

C. Appeal Form Order. The owner or person in charge of or in control of
   the building may appeal to the Board of Appeals the Building Official's
   initial determination that the building is within the scope of this chapter.
   Such appeal shall be filed with the Board in accordance with Section 2-
   12.02 of this Code.

   Appeals or request for slight modifications from any other determinations,
   order or actions by the Building Official pursuant to this chapter, shall be
   made in accordance with the normal appeal procedures established in this
   Code.

D. Recordation. At the time that the aforementioned order is served, the
   Building Official shall file with the Office of the County Recorder a
   certificate stating that the subject building is within the scope of Chapter
   3, Earthquake Hazard Reductions in Existing Unreinforced Masonry
   Buildings. The certificate shall also state that the owner thereof has been
   ordered to structurally analyze the building and to structurally alter or
   demolish it where it is not found to comply with Chapter 3.

   If the building is found not to be within the scope of this chapter, or as a
   result of structural alterations or an analysis is found to be structurally
   capable of resisting minimum seismic forces required by this chapter, or is
   demolished the Building Official shall file with the Office of the County
   Recorder a certificate terminating the status of the subject building as
   being classified within the scope of Chapter 3 Earthquake Hazard
   Reduction in Existing Unreinforced Masonry Buildings.

E. Enforcement. If the owner or other person in charge or control of the
   subject building fails to comply with any order issued by the Building
   Official pursuant to this chapter within any of the time limits set forth in
   Section 8-10.105, the Building Official shall order the entire building
   vacated and remain vacated until such order has been complied with. If
   compliance with such order has not been accomplished within ninety (90)
   days after the date the building has been ordered vacated, or by such
                   additional time as may have been ordered vacated, or by such additional
                   time as may have been granted by the Appeals Board, the Building
                   Official may order the demolition of the building in accordance with the
                   Abatement of Dangerous Building provisions in this Code. (Ord. 360 § 2
                   (part), 1999; Ord. 226 § 1 (part), Exh. A (part), 1991)

8-10.107   Analysis and design.

              A. General. Every structure within the scope of this division shall be
                 analyzed and constructed to resist minimum total lateral seismic forces
                 assumed to act nonconcurrently in the direction of each of the main axes
                 of the structure in accordance with the following equation:

                   V = ZCIW ÷ RW

                   The value of ZCI/RW need not exceed the values set forth in Table 8-
                   10.107A.

                   Exception: The Building Official, upon receipt of adequate justification
                   prepared by a civil or structural engineer or architect licensed by the state,
                   may accept structural analysis and design in accordance with the latest
                   edition of the Uniform Code for Building Conservation, published by the
                   International Conference of Building Officials, as an alternate method of
                   compliance with the provisions of this chapter.

              B.     Lateral Forces on Elements of Structures. Parts or portions of
                   structures shall be analyzed and designed for lateral loads in accordance
                   with Section 8-10.107(a) of this chapter and 2312(g) of the Uniform
                   Building Code but not less than the value from the following equation:

                   Fp = ZICp Wp (UBC 2312)

                   Exception: Unreinforced masonry walls in buildings that are not of a
                   Class I rating may be analyzed in accordance with Section 8-10.108.

                   The value of Cp need not exceed the values set forth in Table 8-10.107C.

              C. Anchorage and Interconnection. Anchorage and interconnection of all
                 parts, portions and elements of the structure shall be analyzed and
                 designed for lateral forces in accordance with Table No. 8-10.107C of this
                 code and the equation Fp = ZECp Wp as modified by Table No. 8-
                 10.107B. Minimum anchorage of masonry walls to each floor or roof shall
                 resist a minimum force of two hundred (200) pounds per lineal foot acting
                 normal to the wall at the level of the floor or roof.

              D. Level of Required Repair. Alterations and repairs required to meet the
                 provisions of this chapter shall comply with all other applicable
                 requirements of the Uniform Building Code unless otherwise specifically
                 provided for in this chapter.

              E. Required Analysis.
             1. General. Except as modified in this chapter, the analysis and design
                relating to the structural alteration of existing structures within the
                scope of this chapter shall be in accordance with the analysis specified
                in Chapter 23 of the UBC.

             2. Continuous Stress Path. A complete, continuous stress path from every
                part or portions of the structure to the ground shall be provided for the
                required horizontal forces.

             3. Positive Connections. All parts, portions or elements of the structure
                shall be interconnected by positive means.

          F. Analysis Procedures.

             1. General. Stresses in materials and existing construction utilized to
                transfer seismic forces from the ground to parts or portions of the
                structure shall conform to those permitted by the Uniform Building
                Code and those materials and types of construction specified in
                Section 8-10.108.

                          accordance with Section 8-10.108.

                  (ii)    An unreinforced masonry wall that carries no design loads
                          other than its own weight may be considered as veneer if it is
                          adequately anchored to new supporting elements.

          G. Combination of Vertical and Seismic Forces.

             1. New Materials. All new materials introduced into the structure to meet
                the requirements of this section that are subjected to combined vertical
                and horizontal forces shall comply with Section 2303 of the Uniform
                Building Code.

             2. Existing Materials. When stresses in existing lateral force resisting
                elements are due to a combination of dead loads plus live loads plus
                seismic loads, the allowable working stress specified in the Uniform
                Building Code may be increased one hundred percent (100%).
                However, no increase will be permitted in the stresses allowed in
                Section 8-10.108, and the stresses in members due only to seismic and
                dead loads shall not exceed the values permitted by Section 2303 (d)
                of the Uniform Building Code.
               3. Allowable Reduction of Bending Stress by Vertical Load. In
                  calculating tensile fiber stress due to seismic forces required by this
                  chapter, the maximum tensile fiber stress may be reduced by the full
                  direct stress due to vertical dead loads.

8-10.108      Materials of construction.

                  A. General. All materials permitted by the Uniform Building Code including
                     their appropriate allowable stresses and those existing configurations of
                     materials specified in this chapter may be utilized to meet the
                     requirements of this chapter.

                  B. Existing Materials.

                     1. Unreinforced Masonry Walls. Unreinforced masonry walls analyzed in
                         accordance with this section may provide vertical support for roof and
                         floor construction and resistance to lateral loads. The facing and
                         backing of such walls shall be bonded so that not less than four (4)
                         percent of the exposed face area is composed of solid headers
                         extending not less than four (4) inches into the backing. The distance
                         between adjacent full-length headers shall not exceed twenty-four (24)
                         inches vertically or horizontally. Where the backing consists of two or
                         more wythes, the header shall extend not less than four (4) inches into
                         the most distant wythe, or the backing wythes shall be bonded together
                         with separate headers whose area and spacing conform to the
                         foregoing.

                         Tension stresses due to seismic forces normal to the wall may be
                         neglected if the walls do not exceed the height to thickness ratio in
                         Table 8-13.108A and the in-plane shear stresses due to seismic loads
                         as set forth in Table No. 8-10.108B.

                         If the wall height-thickness ratio exceeds the specified limits, the wall
                         may be supported by vertical bracing members designed in accordance
                         with this section. The deflections of such bracing member at design
                         loads shall not exceed one-tenth of the wall thickness.

                                 Exception: The wall may be supported by flexible vertical
                                 bracing members designed in accordance with Section 8-
                                 10.107, if the deflection at design loads is not less than one-
                                 quarter nor more than one-third of the wall thickness.

                                 All vertical bracing members shall be attached to floor and roof
                                 construction for their design loads independently of required
                                 wall anchors. Horizontal spacing of vertical bracing members
                                 shall not exceed one-half the unsupported height of the wall
                                 nor ten (10) feet.

                                 The wall height may be measured vertically to bracing
                                 elements other than a floor or roof. Spacing of the bracing
                                 elements and wall anchors shall not exceed six (6) feet. Bracing
                                 elements shall be detailed to minimize the horizontal
                                 displacement of the wall by components of vertical
                                 displacements of the floor or roof.

                      2. Existing Roof, Floors, Walls, Footings and Wood Framing. Existing
                          materials including wood shear walls utilized in the described
                          configuration may be used as part of the later load resisting system,
                          provided that the stresses in these materials does not exceed the value
                          shown in Table No. 8-10.108C.

                  C. Strengthening of Existing Materials. New materials including wood shear
                     walls may be utilized to strengthen portions of the existing seismic
                     resisting systems in the described configurations provided that the stresses
                     do not exceed the values shown in Table No. 8-10.108D.

2
  Bolts and dowels to be 1/2 inch minimum in diameter.

                   D. Alternate Materials. Alternate materials, designs and methods of
                      construction may be approved by the Building Official in accordance with
                      the provisions of the Uniform Building Code.

                   E.    Minimum Acceptable Quality of Existing Unreinforced Masonry
                        Walls:

                        1. General Provisions. All unreinforced masonry walls utilized to carry
                           vertical loads and seismic forces parallel and perpendicular to the wall
                           plant shall be tested as specified in this subsection. All masonry
                           quality shall equal or exceed the minimum standards established
                           herein or shall be removed and replaced by new materials. Alternate
                           methods of testing may be approved by the Building Official. The
                           quality of mortar in all masonry walls shall be determined by
                           performing in-place shear tests or by testing eight (8) inch diameter
                           cores. Alternative methods of testing may be approved by the Building
                           Official. Nothing shall prevent pointing with mortar of all the masonry
                           wall joints before the tests are first made. Prior to any pointing, the
                           mortar joints must be raked and cleaned to remove loose and
                           deteriorated mortar. Mortar for pointing shall be Type S or N except
                           that masonry cements shall not be used. All preparation and mortar
                           pointing shall be done under the continuous inspection of a special
                           inspector certified to inspect masonry or concrete, and approved by the
                           Building Official. At the conclusions of the inspections of, the
                           inspector shall submit a written report to the licensed engineer or
                           architect responsible for the seismic analysis of the building setting
                           forth the result of the work inspected. Such report shall be submitted to
                           the Building Official for approval as part of the structural analysis. All
                           testing shall be performed in accordance with the requirements
                           specified in this subsection by a testing agency approved by the
                           Building Official. An accurate record shall be kept of all such tests and
       of their locations in the building, and these results shall be submitted
       to the Building Official for approval as part of the structural analysis.

   2. Number and Location of Tests. The minimum number of tests shall be
      two per wall or line of wall elements resisting a common force, or one
      (1) per fifteen hundred (1500) square feet of wall surface, with a
      minimum of eight (8) tests in any case. The exact test or core location
      shall be determined at the building site by the licensed engineer or
      architect responsible for the seismic analysis of the subject building.

   3. In-Place Shear Tests. The bed joints of the outer wythe of the masonry
       shall be tested in shear by laterally displacing a single brick relative to
       the adjacent bricks in that wythe. The opposite head joint of the brick
       to be tested shall be removed and cleaned prior to testing. The
       minimum quality mortar in eighty percent (80%) of the shear tests
       shall not be less than the total of thirty (30) psi plus the axial stress in
       the wall at the point of the test. The shear stress shall be based on the
       gross area of both bed joints and shall be that at which movement of
       the brick is first observed.

   4. Core Tests. A minimum number of mortar test specimens equal to the
      number of required cores shall be prepared from the cores and tested
      as specified in this chapter. The mortar joint of the outer wythe of the
      masonry core shall be tested in shear by placing the circular core
      section in a compression testing machine with the mortar bed joint
      rotated fifteen (15) degrees from the axis of the applied load. The
      mortar joint tested in shear shall have an average ultimate stress of
      twenty (20) psi based on the gross area. The average shall be obtained
      from the total number of cores made. If test specimens cannot be made
      from cores taken, then the shear value shall be reported as zero.

F. Testing of Shear Bolts. One-fourth of all new shear bolts and dowels
   embedded in unreinforced masonry walls shall be tested by a Special
   Inspector using a torque calibrated wrench to the following minimum
   torques:

   1/2" diameter bolts or dowels = 40 foot-lbs.
   5/8" diameter bolts or dowels = 50 foot-lbs.
   3/4" diameter bolts or dowels = 60 foot-lbs.

   No bolts exceeding three-fourths (3/4) of an inch shall be used. All nuts
   shall be installed over malleable iron or plate washers when bearing on
   wood and heavy cut washers when bearing on steel.

G. Determination of Allowable Stresses for Design Methods Based on
   Test Results.

   1. Design Shear Values. Design seismic in-plane shear stresses shall be
      substantiated by tests performed as specified in subsections (e)(3) and
      (4) of this section.
                     Design stresses shall be related to test results obtained in accordance
                     with Table No. 8-10.108B. Intermediate values between three (3) and
                     ten (10) psi may be interpolated.

                 2. Design Compressions for Tension Values. Compression stresses for
                    reinforced masonry having a minimum shear value of three (3) psi
                    shall not exceed one hundred (100) psi. Design tension values for
                    unreinforced masonry shall not be permitted.

              H. Tests Required. Five percent (5%) of the existing rod anchors utilized as
                 all or part of the required wall anchors shall be tested in pullout by an
                 approved testing laboratory. The minimum number tested shall be four (4)
                 per floor, with two (2) tests at walls with joist framing into the wall and
                 two (2) tests at walls with joists framing into the wall and two tests at
                 walls with joists parallel to the wall. The test apparatus shall be supported
                 on the masonry wall at a minimum distance of the wall thickness from the
                 anchor tested. The rod anchor shall be given a pre-load of three hundred
                 (300) lbs. prior to establishing a datum for recording elongations. The
                 tension test load reported shall be recorded at one-eighth (1/8) inch
                 relative movement of the anchor and the adjacent masonry surface.

                 Results of all tests shall be reported. The report shall include the test
                 results as related to the wall thickness and joist orientation. The allowable
                 resistance value of the existing anchors shall be forty percent (40%) of the
                 average of those tested anchors having the same wall thickness and joist
                 orientation.

              I. Test Procedures. Qualification tests for devices used for wall anchorage
                 shall be tested with the entire tension load carried on the enlarged head at
                 the exterior face of the wall. Bond on the part of the device between the
                 enlarged head and the interior wall face shall be eliminated for the
                 qualification tests. The resistance value assigned the device shall be
                 twenty percent (20%) of the average of the ultimate loads. (Ord. 360 § 2
                 (part), 1999; Ord. 226 § 1, Exh. A (part), 1991)
