An act to amend Sections 51189, 65302.5, and 66474.02 51189 and 65302.5 of the Government Code, and to amend Sections 4290, 4291, 4291.3, and 4293 of of, and to add Section 4290.5 to, the Public Resources Code, relating to fire safety.

LEGISLATIVE COUNSEL'S DIGEST

AB 2911, as amended, Friedman. Fire safety.

(1) Existing law requires, no later than January 1, 2005, the State Fire Marshal, in consultation with the Director of Forestry and Fire Protection and the Director of Housing and Community Development, to recommend building standards that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading, as provided.

This bill would require the State Fire Marshal, no later than January 31, 2019, in consultation with the Director of Forestry and Fire Protection and the Director of Housing and Community Development, to recommend updated building standards that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading, as specified, based on lessons learned from the wildfires of 2017 and to develop a list of low-cost retrofits that provide for comprehensive site and structure fire risk reduction, as provided.

(2) Existing law requires each planning agency to prepare and the legislative body of each county and city to adopt a comprehensive, long-term general plan, including a safety element, for the physical development of the county or city, as provided. Existing law requires the draft element of or draft amendment to the safety element of a county or city’s general plan to be submitted to the State Board of Forestry and Fire Protection and to every local agency that provides fire protection to territory in the city or county at least 90 days prior to specified events.

This bill would instead require the draft element of or draft amendment to the safety element be submitted to the above-described entities one year six months prior to the specified events.

Existing law requires a county that contains state responsibility areas and a city or county that contains a very high fire hazard severity zone to submit for review the safety element of its general plan to the board and every local agency that provides fire protection to territory in the city or county in accordance with a specified schedule based on location, as provided.

This bill would instead require the safety element to be submitted on January 1, 2019, July 1, 2020, and every 5 years thereafter.

By expanding the responsibilities of a local agency with respect to the submittal of a safety element, the bill would impose a state-mandated local program.

Existing law authorizes the State Board of Forestry and Fire Protection to review and recommend changes to the safety element, as provided. Existing law authorizes the board of supervisors or the city council to consider the changes made by the board.

This bill would authorize the State Board of Forestry and Fire Protection to request a consultation with the board of supervisors or city council if the local agency decides not to adopt the board’s changes, as provided. Because the bill would require local officials to consult with the board, this bill would impose a state-mandated local program.

(3)The Subdivision Map Act vests the authority to regulate and control the design and improvement of subdivisions in the legislative body of a local agency, and sets forth procedures governing the local agency’s processing, approval, conditional approval or disapproval, and filing of tentative, final, and parcel maps, and the modification thereof. The act generally requires a subdivider to file a tentative map or vesting tentative map with the local agency, as specified, and the local agency, in turn, to approve, conditionally approve, or disapprove the map within a specified time period. Before approving a tentative map, or a parcel map for which a tentative map was not required, for an area located in a state responsibility area or a very high fire hazard severity zone, existing law requires the local agency to make specified findings including that the design and location of each lot in the subdivision and the subdivision as a whole are consistent with any regulations adopted by the Board of Forestry and Fire Protection relating to buildings or structures in hazardous fire areas or mountainous, forest, brush, and grass-covered lands, as provided.

This bill would instead require a finding that the subdivision is consistent with any regulations adopted by the board relating to buildings or structures in hazardous fire areas. The bill would require the local agency, upon approval of the tentative map in specified situations, to transmit a copy of the findings and maps to the board.

(4)

(3) Existing law requires the State Board of Forestry and Fire Protection to adopt regulations implementing minimum fire safety standards related to defensible space applicable to state responsibility area lands, as provided.

This bill would require, on or before July 1, 2019, the board to initiate a rulemaking process to consider adopting regulations requiring a minimum of 2 separate access roads for a subdivision, as defined, located in a state responsibility area or a very high fire hazard severity zone.

This bill would require, on or before July 1, 2021, and every 5 years thereafter, the board, in consultation with the State Fire Marshal, to survey local governments and fire districts to identify existing subdivisions, as defined, in either a state responsibility area or a very high fire hazard severity zone, without secondary egress routes, that are at significant fire risk. The bill would require the board, in consultation with the State Fire Marshal and the local governments identified above, to develop recommendations to improve the subdivision’s fire safety, as provided. The bill would require the board to provide final recommendations to the identified local governments.

(4) Existing law requires the Department of Forestry and Fire Protection to develop, periodically update, and post on its Internet Web site a guidance document on fuels management. Existing law requires the guidance to include, but not be limited to, regionally appropriate vegetation management suggestions that preserve and restore native species.

This bill would limit these native species for purposes of the guidance document to those that are fire retardant, fire resistant, or drought tolerant, or any combination thereof.

(5) Existing law authorizes a state or local fire official to authorize an owner of property or his or her agent to construct a firebreak, or implement appropriate vegetation management techniques, to ensure that defensible space is adequate for the protection of a hospital, adult residential care facility, school, aboveground storage tank, hazardous materials facility, or similar facility on the property.

This bill would authorize the director of the Department of Forestry and Fire Protection to authorize an owner of any other property not listed above to construct a firebreak, as provided, if it is determined by the director as necessary to protect life, property, and natural resources from unreasonable risks associated with wild land fires.

(6) Existing law requires a person that owns, controls, operates, or maintains an electrical transmission or distribution line upon mountainous land, or in forest-covered land, brush-covered land, or grass-covered land, to maintain certain clearances between all vegetation and all conductors that are carrying electric current during those times and in those areas determined to be necessary by the Director of Forestry and Fire Protection or the agency with primary responsibility for the fire protection of those areas.

This bill would increase the clearance distance for lines operating at 2,400 to 110,000 volts, as provided, and would require any service drop operating at more than 750 volts but less than 2,400 volts to have a clearance distance of 4 feet. The bill would require clearance distance to be measured from the outermost point of hardware, as provided.

This bill would instead require a person that owns, controls, operates, or maintains an electrical transmission or distribution line upon mountainous land, or in forest-covered land, brush-covered land, or grass-covered land, to maintain certain clearances between all vegetation and all conductors that are carrying electric current in those areas determined to be necessary by the Director of Forestry and Fire Protection or the agency with primary responsibility for the fire protection of those areas.

Existing law requires dead trees, old decadent or rotten tress, trees weakened by decay or disease, and trees or portions of the trees that are leaning toward a line that may contact the line from the side or may fall on the line to be felled, cut, or trimmed so as to remove the hazard.

This bill would instead require dead, rotten, or diseased trees, or dead, rotten, or diseased portions of otherwise healthy trees, that overhang or lean towards and may fall into a line to be felled, cut, or trimmed so as to remove the hazard. The bill would require that any tree removed pursuant to this provision be replaced, when feasible, with vegetation that at maturity does not come into contact with conductors, as provided.

(7) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.

Bill Text

The people of the State of California do enact as follows:

SECTION 1.

 (a) The Legislature finds and declares all of the following:

(1) The 2017 fire season was devastating. Over 1.3 million acres burned in high-severity wildfires and over 10,000 structures were destroyed from wildfires across the state.

(2) Forty-three Forty-four people died in the 2017 fire season, higher than the last 10 years combined.

(3) Last year’s Thomas fire in Ventura and Santa Barbara was the largest recorded fire in California history. There were also significant fires throughout the state including in Los Angeles, Napa, and Sonoma Counties.

(4) CAL FIRE and the State Board of Forestry and Fire Protection have recognized that California now often experiences a year-round fire season, with an increase in both the number and the intensity of large, damaging wildfires.

(5) The increase in frequency and intensity of large wildfires is due to a century of fire exclusion and the impacts of climate change.

(6) Governor Brown has declared these wildfire threats as the “new normal” in California.

(b) It is therefore the intent of the Legislature to strengthen requirements that improve defensible space protections, increase the use of fire-resistant building materials, and improve the fire safety of California communities.

SEC. 2.

 Section 51189 of the Government Code is amended to read:

51189.

 (a) The Legislature finds and declares that site and structure defensibility is essential to reduce the risk of structure ignition as well as for effective fire suppression by firefighters. This need to establish defensibility extends beyond the site fuel management practices required by this chapter, and includes, but is not limited to, measures that increase the likelihood of a structure to withstand ignition, such as building design and construction requirements that use fire resistant building materials, and provide standards for reducing fire risks on structure projections, including, but not limited to, porches, decks, balconies and eaves, and structure openings, including, but not limited to, attic, foundation, and eave vents, doors, and windows.

(b) No later than January 31, 2019, the State Fire Marshal, in consultation with the Director of Forestry and Fire Protection and the Director of Housing and Community Development, shall, pursuant to Section 18930 of the Health and Safety Code, recommend updated building standards that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading from adjacent structures or vegetation and to protect vegetation from fires spreading from adjacent structures, based on information learned from the 2017 wildfire season.

(c) (1) No later than January 31, 2019, the State Fire Marshal, in consultation with the Director of Forestry and Fire Protection and the Director of Housing and Community Development, shall develop a list of low-cost retrofits that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading from adjacent structures or vegetation and to protect vegetation from fires spreading from adjacent structures. The department shall incorporate the list in its fire prevention education and outreach efforts.

(2) In addition to the requirements of paragraph (1), the list shall include instructions on how to replace highly flammable plants with native plant species that are fire retardant, fire resistant, or drought tolerant, or any combination thereof.

SEC. 3.

 Section 65302.5 of the Government Code is amended to read:

65302.5.

 (a) At least 45 days prior to adoption or amendment of the safety element, each county and city shall submit to the California Geological Survey of the Department of Conservation one copy of a draft of the safety element or amendment and any technical studies used for developing the safety element. The division may review drafts submitted to it to determine whether they incorporate known seismic and other geologic hazard information, and report its findings to the planning agency within 30 days of receipt of the draft of the safety element or amendment pursuant to this subdivision. The legislative body shall consider the division’s findings prior to final adoption of the safety element or amendment unless the division’s findings are not available within the above prescribed time limits or unless the division has indicated to the city or county that the division will not review the safety element. If the division’s findings are not available within those prescribed time limits, the legislative body may take the division’s findings into consideration at the time it considers future amendments to the safety element. Each county and city shall provide the division with a copy of its adopted safety element or amendments. The division may review adopted safety elements or amendments and report its findings. All findings made by the division shall be advisory to the planning agency and legislative body.

(b) (1) The draft element of or draft amendment to the safety element of a county or a city’s general plan shall be submitted to the State Board of Forestry and Fire Protection and to every local agency that provides fire protection to territory in the city or county at least one year six months prior to either of the following:

(A) The adoption or amendment to the safety element of its general plan for each county that contains state responsibility areas.

(B) The adoption or amendment to the safety element of its general plan for each city or county that contains a very high fire hazard severity zone as defined pursuant to subdivision (i) of Section 51177.

(2) A county that contains state responsibility areas and a city or county that contains a very high fire hazard severity zone as defined pursuant to subdivision (i) of Section 51177 shall submit for review the safety element of its general plan to the State Board of Forestry and Fire Protection and every local agency that provides fire protection to territory in the city or county on January 1, 2019, July 1, 2020, and every five years thereafter.

(3) The State Board of Forestry and Fire Protection shall, and a local agency may, review the draft or an existing safety element and recommend changes to the planning agency within 60 days of its receipt regarding both of the following:

(A) Uses of land and policies in state responsibility areas and very high fire hazard severity zones that will protect life, property, and natural resources from unreasonable risks associated with wild land fires.

(B) Methods and strategies for wild land fire risk reduction and prevention within state responsibility areas and very high fire hazard severity zones.

(4) (A) Prior to the adoption of its draft element or draft amendment, the board of supervisors of the county or the city council of a city shall consider the recommendations, if any, made by the State Board of Forestry and Fire Protection and any local agency that provides fire protection to territory in the city or county. If the board of supervisors or city council determines not to accept all or some of the recommendations, if any, made by the State Board of Forestry and Fire Protection or local agency, the board of supervisors or city council shall communicate in writing to the State Board of Forestry and Fire Protection or the local agency, its reasons for not accepting the recommendations.

(B) If the board of supervisors or city council proposes not to adopt the board’s recommendations concerning its draft element or draft amendment, the board, within 15 days of receipt of the board of supervisors’ or city council’s written response, may request in writing a consultation with the board of supervisors or city council to discuss the board’s recommendations and the board of supervisors’ or city council’s response. The consultation may be conducted in person, electronically, or telephonically. If the board requests a consultation pursuant to this subparagraph, the board of supervisors or city council shall not approve the draft element or draft amendment until after consulting with the board. The consultation shall occur no later than 30 days after the board’s request.

(5) If the State Board of Forestry and Fire Protection’s or local agency’s recommendations are not available within the time limits required by this section, the board of supervisors or city council may act without those recommendations. The board of supervisors or city council shall take the recommendations into consideration the next time it considers amendments to the safety element.

SEC. 4.Section 66474.02 of the Government Code is amended to read:

66474.02.

(a)(1)Before approving a tentative map, or a parcel map for which a tentative map was not required, for an area located in a state responsibility area or a very high fire hazard severity zone, as both are defined in Section 51177, a legislative body of a county shall, except as provided in subdivision (b), make the following three findings:

(A)A finding supported by substantial evidence in the record that the subdivision is consistent with any applicable regulations adopted by the State Board of Forestry and Fire Protection pursuant to Section 4291 of the Public Resources Code.

(B)A finding supported by substantial evidence in the record that structural fire protection and suppression services will be available for the subdivision through any of the following entities:

(i)A county, city, special district, political subdivision of the state, or another entity organized solely to provide fire protection services that is monitored and funded by a county or other public entity.

(ii)The Department of Forestry and Fire Protection by contract entered into pursuant to Section 4133, 4142, or 4144 of the Public Resources Code.

(C)A finding that, to the extent practicable, ingress and egress for the subdivision meets or exceeds the requirements of the regulations regarding road standards for fire equipment access adopted pursuant to Section 4290 of the Public Resources Code and any applicable local ordinance.

(2)Upon approving a tentative map, or a parcel map for which a tentative map was not required, for an area located in a state responsibility area or a very high fire hazard severity zone, as both are defined in Section 51177, a legislative body of a county shall transmit a copy of the findings required in this subdivision and accompanying maps to the State Board of Forestry and Fire Protection.

(b)(1)Subdivision (a) does not apply to the approval of a tentative map, or a parcel map for which a tentative map was not required, that would subdivide land identified in the open space element of the general plan for the managed production of resources, including, but not limited to, forest land, rangeland, agricultural land, and areas of economic importance for the production of food or fiber, if the subdivision is consistent with the open space purpose and if, for the subdivision of land that would result in parcels that are 40 acres or smaller in size, those parcels are subject to a binding and recorded restriction prohibiting the development of a habitable, industrial, or commercial building or structure. All other structures shall comply with defensible space requirements described in Section 51182 of this code or Section 4291 of the Public Resources Code.

(2)Any later approval to remove a binding restriction placed as a condition of a tentative map, or a parcel map for which a tentative map was not required, that would allow the development of a building or structure for a parcel that has previously been exempted from the requirements of subdivision (a) pursuant to paragraph (1) of this subdivision shall be subject to the requirements of subdivision (a).

(c)This section does not supersede regulations established by the State Board of Forestry and Fire Protection or local ordinances that provide equivalent or more stringent minimum requirements than those contained within this section.

SEC. 5.Section 4290 of the Public Resources Code is amended to read:

4290.

(a)The board shall adopt regulations implementing minimum fire safety standards related to defensible space which are applicable to state responsibility area lands under the authority of the department. These regulations apply to the perimeters and access to all residential, commercial, and industrial building construction within state responsibility areas approved after January 1, 1991. The board may not adopt building standards, as defined in Section 18909 of the Health and Safety Code, under the authority of this section. As an integral part of fire safety standards, the State Fire Marshal has the authority to adopt regulations for roof coverings and openings into the attic areas of buildings specified in Section 13108.5 of the Health and Safety Code. The regulations apply to the placement of mobile homes as defined by National Fire Protection Association standards. These regulations do not apply where an application for a building permit was filed prior to January 1, 1991, or to parcel or tentative maps or other developments approved prior to January 1, 1991, if the final map for the tentative map is approved within the time prescribed by the local ordinance. The regulations shall include all of the following:

(1)Road standards for fire equipment access.

(2)Standards for signs identifying streets, roads, and buildings.

(3)Minimum private water supply reserves for emergency fire use.

(4)Fuel breaks and greenbelts.

(b)These regulations do not supersede local regulations which equal or exceed minimum regulations adopted by the state.

(c)(1)On or before July 1, 2019, the board shall initiate a rulemaking process to consider adopting regulations requiring a minimum of two separate access roads for a subdivision located in a state responsibility area or a very high fire hazard severity zone. If adopted, the rule shall be applicable so as to require at least two separate access roads, based on, among other things, the geographical and topographical situation of a subdivision, the feasibility of requiring two separate access roads, ownership patterns, the ability of future phases to provide access, and the predominant known wind patterns.

(2)For purposes of this subdivision, “subdivision” means a proposed residential development of more than 500 dwelling units, except that for a public water system that has fewer than 5,000 service connections, “subdivision” means any proposed residential development that would account for an increase of 10 percent or more in the number of the public water system’s existing service connections.

SEC. 4.

 Section 4290.5 is added to the Public Resources Code, to read:

4290.5.

 (a) On or before July 1, 2021, and every five years thereafter, the board, in consultation with the State Fire Marshal, shall survey local governments, including counties, cities, and fire districts to identify existing subdivisions located in a state responsibility area or a very high fire hazard severity zone, identified pursuant to Section 51178 of the Government Code, without a secondary egress route that are at significant fire risk.

(b) (1) The board, in consultation with the State Fire Marshal and the local government that identified the subdivision, shall develop recommendations to improve the subdivision’s fire safety. The recommendations may include, but are not limited to, the following:

(A) Creating secondary access to the subdivision.

(B) Improvements to the existing access road.

(C) Other additional fire safety measures.

(2) The board shall provide the final recommendations developed pursuant to this subdivision to the local government that identified the subdivision and to the residents of the subdivision.

(c) The board may enter into contracts with an independent group to conduct the survey required in subdivision (a).

(d) For purposes of this section, “subdivision” means an existing residential development of more than 30 dwelling units.

(e) The board shall maintain a list of the subdivisions identified in subdivision (a) and the status of the implementation of the recommendations provided pursuant to subdivision (b).

SEC. 5.

 Section 4291 of the Public Resources Code is amended to read:

4291.

 (a) A person who owns, leases, controls, operates, or maintains a building or structure in, upon, or adjoining a mountainous area, forest-covered lands, brush-covered lands, grass-covered lands, or land that is covered with flammable material, shall at all times do all of the following:

(1) Maintain defensible space of 100 feet from each side and from the front and rear of the structure, but not beyond the property line except as provided in paragraph (2). The amount of fuel modification necessary shall take into account the flammability of the structure as affected by building material, building standards, location, and type of vegetation. Fuels shall be maintained in a condition so that a wildfire burning under average weather conditions would be unlikely to ignite the structure. This paragraph does not apply to single specimens of trees or other vegetation that are well-pruned and maintained so as to effectively manage fuels and not form a means of rapidly transmitting fire from other nearby vegetation to a structure or from a structure to other nearby vegetation. The intensity of fuels management may vary within the 100-foot perimeter of the structure, the most intense being within the first 30 feet around the structure. Consistent with fuels management objectives, steps should be taken to minimize erosion. For the purposes of this paragraph, “fuel” means any combustible material, including petroleum-based products and wildland fuels.

(2) A greater distance than that required under paragraph (1) may be required by state law, local ordinance, rule, or regulation. Clearance beyond the property line may only be required if the state law, local ordinance, rule, or regulation includes findings that the clearing is necessary to significantly reduce the risk of transmission of flame or heat sufficient to ignite the structure, and there is no other feasible mitigation measure possible to reduce the risk of ignition or spread of wildfire to the structure. Clearance on adjacent property shall only be conducted following written consent by the adjacent landowner.

(3) An insurance company that insures an occupied dwelling or occupied structure may require a greater distance than that required under paragraph (1) if a fire expert, designated by the director, provides findings that the clearing is necessary to significantly reduce the risk of transmission of flame or heat sufficient to ignite the structure, and there is no other feasible mitigation measure possible to reduce the risk of ignition or spread of wildfire to the structure. The greater distance may not be beyond the property line unless allowed by state law, local ordinance, rule, or regulation.

(4) Remove that portion of a tree that extends within 10 feet of the outlet of a chimney or stovepipe.

(5) Maintain a tree, shrub, or other plant adjacent to or overhanging a building free of dead or dying wood.

(6) Maintain the roof of a structure free of leaves, needles, or other vegetative materials.

(7) Prior to constructing a new building or structure or rebuilding a building or structure damaged by a fire in an area subject to this section, the construction or rebuilding of which requires a building permit, the owner shall obtain a certification from the local building official that the dwelling or structure, as proposed to be built, complies with all applicable state and local building standards, including those described in subdivision (b) of Section 51189 of the Government Code, and shall provide a copy of the certification, upon request, to the insurer providing course of construction insurance coverage for the building or structure. Upon completion of the construction or rebuilding, the owner shall obtain from the local building official, a copy of the final inspection report that demonstrates that the dwelling or structure was constructed in compliance with all applicable state and local building standards, including those described in subdivision (b) of Section 51189 of the Government Code, and shall provide a copy of the report, upon request, to the property insurance carrier that insures the dwelling or structure.

(b) A person is not required under this section to manage fuels on land if that person does not have the legal right to manage fuels, nor is a person required to enter upon or to alter property that is owned by any other person without the consent of the owner of the property.

(c) (1) Except as provided in Section 18930 of the Health and Safety Code, the director may adopt regulations exempting a structure with an exterior constructed entirely of nonflammable materials, or, conditioned upon the contents and composition of the structure, the director may vary the requirements respecting the removing or clearing away of flammable vegetation or other combustible growth with respect to the area surrounding those structures.

(2) An exemption or variance under paragraph (1) shall not apply unless and until the occupant of the structure, or if there is not an occupant, the owner of the structure, files with the department, in a form as the director shall prescribe, a written consent to the inspection of the interior and contents of the structure to ascertain whether this section and the regulations adopted under this section are complied with at all times.

(d) The director may authorize the removal of vegetation that is not consistent with the standards of this section. The director may prescribe a procedure for the removal of that vegetation and make the expense a lien upon the building, structure, or grounds, in the same manner that is applicable to a legislative body under Section 51186 of the Government Code.

(e) The Department of Forestry and Fire Protection department shall develop, periodically update, and post on its Internet Web site a guidance document on fuels management pursuant to this chapter. Guidance shall include, but not be limited to, regionally appropriate vegetation management suggestions that preserve and restore native species, species that are fire retardant, fire resistant, or drought tolerant, or any combination thereof, minimize erosion, minimize water consumption, and permit trees near homes for shade, aesthetics, and habitat; and suggestions to minimize or eliminate the risk of flammability of nonvegetative sources of combustion such as woodpiles, propane tanks, decks, and outdoor lawn furniture.

(f) As used in this section, “person” means a private individual, organization, partnership, limited liability company, or corporation.

SEC. 6.

 Section 4291.3 of the Public Resources Code is amended to read:

4291.3.

 (a) Subject to any other applicable law, a state or local fire official, at his or her discretion, may authorize an owner of property, or his or her agent, to construct a firebreak, or implement appropriate vegetation management techniques, to ensure that defensible space is adequate for the protection of a hospital, adult residential care facility, school, aboveground storage tank, hazardous materials facility, or similar facility on the property. The firebreak may be for a radius of up to 300 feet from the facility, or to the property line, whichever distance is shorter.

(b) The director may authorize an owner of a property not listed in subdivision (a) to construct a firebreak with a radius of up to 300 feet from a structure, or to the property line line, whichever distance is shorter, if it is determined by the director as necessary to protect life, property, and natural resources from unreasonable risks associated with wild land fires.

SEC. 7.

 Section 4293 of the Public Resources Code is amended to read:

4293.

 (a) (1)Except as otherwise provided in Sections 4294 to 4296, inclusive, a person that owns, controls, operates, or maintains an electrical transmission or distribution line upon a mountainous land, or in forest-covered land, brush-covered land, or grass-covered land shall, during the times and in the areas as are determined to be necessary by the director or the agency that has primary responsibility for the fire protection of the areas, maintain a clearance of the respective distances that are specified in this section in all directions between all vegetation and all conductors that are carrying electric current, as follows:

(A)For a service drop operating at more than 750 volts but less than 2,400 volts, four feet.

(B)

(1) For a line that is operating at 2,400 or more volts, but less than 72,000 volts, six four feet.

(C)

(2) For a line that is operating at 72,000 or more volts, but less than 110,000 volts, eight six feet.

(D)

(3) For a line that is operating at 110,000 or more volts, 10 feet.

(2)Clearance distance shall be measured from the outermost point of hardware. Clearance distance shall be adjusted for slope, such that specified distances are cleared horizontally from hardware.

(b) (1) In every case, the distance required pursuant to subdivision (a) shall be sufficiently great to furnish the required clearance at any position of the wire, or conductor when the adjacent air temperature is 120 degrees Fahrenheit, or less. All vegetation, including, but not limited to, green vegetation, branches, limbs, dead trees, old decadent or rotten trees, trees weakened by decay or disease and trees or portions thereof that are leaning toward the line that may contact the line from the side or may fall on the line Dead, rotten, or diseased trees, or dead, rotten, or diseased portions of otherwise healthy trees that overhang or lean towards and may fall into a line shall be felled, cut, or trimmed so as to remove the hazard. Complete vertical Vertical clearance of vegetation above hardware conductors shall be maintained evaluated, and any hazard shall be removed, to prevent limb drop. The director or the agency that has primary responsibility for the fire protection of the areas may permit exceptions from the requirements of this section that are based upon the specific circumstances involved.

(b) (2) Any dead, rotten, or diseased tree removed pursuant to this section shall, when feasible, be replaced with vegetation that, at maturity, does not come in contact with conductors. Native vegetation that provides habitat benefits shall be used for the replacement if feasible.

SEC. 8.

 If the Commission on State Mandates determines that this act contains costs mandated by the state, reimbursement to local agencies and school districts for those costs shall be made pursuant to Part 7 (commencing with Section 17500) of Division 4 of Title 2 of the Government Code.
