A. 
The city council of the City of Roseville finds and declares that the additions, modifications, and changes made to these codes are necessary for the protection of the public health, safety, and welfare due to climatic, geological, or topographical conditions. These amendments are authorized under Health and Safety Code Section 17958 and are identified as follows:
1. 
Climatic. Average yearly rainfall for the city is approximately 18 inches; with the majority occurring between October and April. During the summer months, there is generally no measurable precipitation and temperatures for this dry period range from 70 to 112 degrees Fahrenheit. Pools are common as a result of the high summer temperatures. High summer month temperatures are frequently accompanied by light to gusty westerly and northerly winds. The relative humidity during the summer months averages from two to 30 millimeters of mercury (Hg), which is considered arid. The city is surrounded by thousands of acres of grasslands which, during the summer months are dried to the point at which they are exceedingly combustible and easily ignited.
2. 
Topographical. The city is segmented by several topographical and physical features, including minor rivers, steep canyons, natural parkways, open space, freeways, railroad tracks, drainage canals, and sprawling industrial facilities. Heavy traffic congestion on city streets acts as a barrier for fire and emergency vehicles providing timely response. Preservation of wetland areas, natural parkways, riparian corridors, vernal pools, open space, and endangered species' habitats have all contributed to access problems while also resulting in exemptions from vegetation reduction programs. These situations, though environmentally important, increase the demands on the fire department due to extreme fire hazards created by increased fuel loading and access limitations. These conditions also result in natural aquifers that the city uses for water, resulting in differing water sources.
3. 
Geological. The city is located within a Seismic Design Category D area and is subject to ground tremors. Flooding has occurred in the portions of the city that lie adjacent to Roseville's numerous creeks and streams.
B. 
The building official is authorized to render interpretations of this code and make and enforce rules and supplemental regulations in order to carry out its application. The building official maybe guided by future supplements to the California Building Code. Such interpretations, rules and regulations and supplements shall conform with the intent and purpose of the California Building Code and shall be available to the public during normal business hours.
C. 
When there are practical difficulties involved in carrying out the provisions of this code, the building official may grant modifications for individual cases. The building official shall first find that a special individual reason makes the strict letter of this code impractical and that the modification is in conformance with the intent and purpose of this code and that such modification does not lessen any fire-protection requirements or any degree of structural integrity. The details of any action granting modifications shall be recorded and entered in the files of the City of Roseville.

"Equipment"

Section 3109.2 of the California Building Code is amended to add the following language at the end of Section 3109.2:
Notwithstanding the foregoing, with regard to Health and Safety Code Section 115922 requiring at least two of seven drowning prevention safety features, at least one of the two drowning prevention safety features required must be an enclosure that meets the requirements of Section 115923 and isolates the swimming pool or spa from any private single-family home. The intent of this section is to ensure that when a building permit is issued for the construction of a new swimming pool or spa or the remodeling of an existing swimming pool or spa at a private single-family home, the respective swimming pool or spa shall have an enclosure that meets the requirements of Section 115923 and isolates the swimming pool or spa from neighboring private single­family homes.
