MOORPARK CITY COUNCIL AGENDA REPORT TO: Honorable City Council FROM: David A. Bobardt, Community Development Director By: Ray Young, Charles Abbott Associates, Building Official DATE: October 4, 2013 (CC Meeting of 10/16/2013) SUBJECT: Consider an Ordinance Amending Title 15 of the Moorpark Municipal Code by Replacing in Their Entirety Chapters 15.04, 15.08, 15.10, 15.12, 15.14, 15.16, 15.18, 15.20 and 15.22 as Well as Adopting by Reference and Amending the Current Editions of Certain Model Codes and Determination of Exemption under CEQA in Connection Therewith BACKGROUND/DISCUSSION New building standards have been adopted by the State to take effect on January 1, 2014. These codes include the California Building Code, 2013 Edition, Volumes 1 and 2, with Appendices C, F, H, I and J; California Residential Code, 2013 Edition, with Appendices E, G and H; California Referenced Standards, 2013 Edition; California Electrical Code, 2013 Edition; California Plumbing Code, 2013 Edition; California Mechanical Code, 2013 Edition; California Energy Code, 2013 Edition; California Green Building Standards Code, 2013 Edition; California Administrative Code, 2013 Edition; International Property Maintenance Code, 2012 Edition and the Gypsum Association Fire Resistance Design Manual, Twentieth Edition. The State of California Health and Safety Code requires all jurisdictions to enforce the most recent editions of these various building standards. Although the State requires the enforcement of certain standards, it allows the City to amend these standards in order to address local concerns. The State, however, does limit the City's ability to amend the prescribed building standards to amendments that are stricter than State standards and are reasonably necessary for reasons relating to local climate, geology and topography. The proposed Ordinance (attached), which would take effect on January 1, 2014 concurrently with the new State standards, includes adoption of the State standards, along with amendments to specific building code sections dealing with administration S:\Community Development\BLDG\Building Code\2013 Update\20131016 CC agenda report.docx 2 Honorable City Council October 16, 2013 Page 2 and fees as well as changes to the building standards to improve public safety with respect especially to earthquakes and fire hazards. The proposed amendments in the Ordinance were developed and recommended by local building officials and engineers in conjunction with the Structural Engineers Association of California (SEAC). SEAC, the City of Los Angeles and the cities of Ventura County as a unified consortium agreed to recommend adoption of these additional amendments (which exceed the 2013 California Building Standards Codes) given unique climatic, geological and topographical conditions that impact our local environment pursuant to Section 17958.5 of the Health and Safety Code. The proposed amendments to the 2013 California Building Code, Residential Code, and Green Building Standards Code are essentially the same as those made to the 2010 codes by City Ordinances 395 and 399. Because of the proposed amendments, State law requires that the Council direct staff to advertise a public hearing to be held at least fifteen (15) days prior to consideration of second reading of the ordinance. Additionally, the City is required to send the amendments to the State. The City Attorney has reviewed and approved the form of the Ordinance. ENVIRONMENTAL DETERMINATION This ordinance with proposed amendments to Title 15 of the Moorpark Municipal Code is exempt from the provisions of the California Environmental Quality Act pursuant to Section 15061(b)(3) of the California Code of Regulations (CEQA Guidelines) by the general rule that CEQA only applies to "projects" that may have a significant effect on the environment. The proposed ordinance would amend the Municipal Code related to building standards necessary to protect health and safety. In this case, it can be seen with certainty that there is no possibility that the proposed Ordinance may have a significant impact on the environment. FISCAL IMPACT None. STAFF RECOMMENDATION Introduce Ordinance No. , amending Title 15 of the Moorpark Municipal Code, for first reading, waive full reading, and direct staff to schedule a public hearing and second reading and adoption of this ordinance for November 6, 2013.

ENVIRONMENTAL DETERMINATION: The City Council has reviewed the Community Development Director's determination that this ordinance with proposed amendments to Title 15 of the Moorpark Municipal Code is exempt from the provisions of the California Environmental Quality Act pursuant to Section 15061(b)(3) of the California Code of Regulations (CEQA Guidelines) by the general rule that CEQA only applies to "projects" that may have a significant effect on the environment. The proposed ordinance would amend the Municipal Code related to building standards necessary to protect health and safety. In this case, it can be seen with certainty that there is no possibility that the proposed Ordinance may have a significant impact on the environment. The City Council, based on its own independent judgment, concurs with staff's determination of Exemption. SECTION 2. Chapters 15.04 (Administrative Provisions), 15.08 (Building Code), 15.10 (California Green Building Standards Code), 15.12 (Electrical Code), 15.14 (Plumbing Code), 15.16 (Mechanical Code), 15.18 (Housing Code), 15.20 (California Energy Code), and 15.22 (California Residential Code) of Title 15 (Buildings and Construction) of the Moorpark Municipal Code are replaced in their entirety as shown in Exhibit A. SECTION 3. AMENDMENTS NECESSARY. Pursuant to Section 17958.7 of the Health and Safety Code of the State of California, the City Council of the City of Moorpark hereby finds that each amendment to the 2013 Editions of the California Building Code, the California Residential Code and the Green Building Standards Code made by this Ordinance is reasonably necessary due to local climatic, geological and topographical conditions as follows: Local Climatic Conditions — The local climate is characterized by periods of high temperatures accompanied by low humidity and high winds each year. These conditions could create an environment in which the fire department may have great difficulty in controlling fires occurring in hillside brush areas as well as structures not having built-in fire protection. The City also experiences periods of intense rainfall, which create the need for special drainage precautions. Local Geological Conditions — The Moorpark/Ventura County region is a populated area having buildings constructed over and near fault systems capable of producing major earthquakes. The City is located in an area with expansive soils and areas subject to flood hazards including hillsides that are subject to mud flows and unstable soils. These conditions require that special foundation considerations and soils analysis requirements must be in place to provide a reasonable degree of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons using public property. 6 Ordinance No. 427 Page 4 Local Topographical Conditions — The City contains and is located near hillside brush areas, so special fire resistive requirements are required in order to reduce fire damage and fire spread during periods of high temperatures and low humidity. This requires special construction elements for structures in the City to reduce the threat of fire damage and fire spread during periods of high temperatures and low humidity. These local climatic, geological and topographical conditions require specific and greater protection than is afforded by the 2013 Editions of the California Building Code, the California Residential Code and the California Green Building Standards Code. SECTION 4. If any section, subsection, sentence, clause, phrase, part or portion of this Ordinance is for any reason held to be invalid or unconstitutional by any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this Ordinance. The City Council declares that it would have adopted this Ordinance and each section, subsection, sentence, clause, phrase, part or portion thereof, irrespective of the fact that any one or more section, subsections, sentences, clauses, phrases, parts or portions be declared invalid or unconstitutional. SECTION 5. This Ordinance shall become effective on January 1, 2014. SECTION 6. The City Clerk shall certify to the passage and adoption of this ordinance; shall enter the same in the book of original ordinances of said City; shall make a minute of the passage and adoption thereof in the records of the proceedings of the City Council at which the same is passed and adopted; and shall publish notice of adoption in the manner required by law.
