19.76.010 Purpose.
The purpose of this chapter is to establish minimum wildfire and safety mitigation standards for development, replacement, substantial improvement or relocation of structures. This chapter is intended to reduce threats to human life and safety, to structures and to wild lands, and to improve access in emergencies.
It is also the intent of this chapter to achieve the greatest possible application of wildfire and emergency safety standards by covering new dwellings where authorized as permitted uses. In order to achieve this objective, this chapter shall provide for reduced review and approval procedures for new, replacement of, substantially improved and relocated dwellings in other zones, as specified in JCC 19.76.020(D) and 19.76.100(A). [2005 RLDC § 76.010.]
19.76.020 Application of wildfire and emergency safety standards.
The development and construction standards contained in this chapter shall be applied during the review and approval of the following land use actions:
A. Land Divisions. Land divisions in any zone approved pursuant to Division V of this title shall be required to develop wildfire mitigation plans that assure safety of the whole development, and that assure individual lots or parcels within the land division are able to comply with the provisions of this chapter. The Review Body shall apply the standards contained in this chapter to the extent needed to assure that its purposes are met.
B. Site Plan Review and Conditional Use Permits. Any land development that requires review and approval pursuant to the provisions of Chapter 19.42 JCC (Site Plan Review) or Chapter 19.45 JCC (Conditional Use Permit) shall be required to develop wildfire mitigation plans that assure safety of the development. The Review Body shall apply the standards contained in this chapter to assure that its purposes are met.
C. Forest Zones. The development of new structures, the substantial improvement of existing structures, the relocation of structures and the replacement of structures in forest zones (Chapter 19.65 JCC) shall meet the requirements of this chapter.
D. Other Zones. The development of new dwellings in any zone other than the forest zones shall demonstrate compliance with all of the applicable standards of this chapter. The relocation or replacement of existing dwellings in any zone other than the forest zones shall be required to demonstrate compliance with the standards for construction (JCC 19.76.030), fire protection service or on-site fire protection plan (JCC 19.76.060) and vegetation mitigation (JCC 19.76.080) only. Improvements to existing dwellings must only comply with the standards for construction (JCC 19.76.030), except for roofing requirements, as they apply to the new construction and not the existing structure or structures. Compliance for all types of development under this section shall be accomplished by meeting the application and self-certification requirements contained in JCC 19.76.100(A).
E. Other Requirements. Nothing in this chapter is intended to waive or diminish any other development standard, regulation or other provision required in this title or elsewhere. [2005 RLDC § 76.020.]
19.76.030 Site development and construction standards.
A. Steep Slopes. Slopes in excess of 40 percent may be disturbed or altered only after the disturbance or alteration is authorized pursuant to the requirements for modification of standards contained in JCC 19.76.090. Dwellings in forest zones shall not be sited on slopes greater than 40 percent.
NOTE: Site development that disturbs ground with slopes at or above 15 percent, or that have granitic soils, requires an approved erosion control plan prepared by a registered engineer before disturbance. See Article 83, Erosion Control and Storm Drain Facilities.
B. Construction of Structures. The development of new structures and the substantial improvement, relocation and replacement of existing structures shall implement the following construction features:
1. Roofing materials shall meet fire rating class A or B as established by the National Fire Protection Association. Exterior wood roofing of any type is prohibited.
2. Chimneys and stove pipes shall be capped with a spark arrester that meets the standards established by the National Fire Protection Association.
3. The exposed undersides of porches, decks and balconies three feet or less above the ground shall be enclosed with one-fourth inch or smaller noncombustible, corrosion resistant metal mesh.
4. Areas beneath decks, porches, balconies and roofs greater than three feet above the ground shall be maintained free of combustible materials.
5. Attic openings, soffit vents, foundation louvers and vents and other direct openings in outside walls, overhangs and roofs shall be no larger than 144 square inches and shall be covered with one-fourth inch noncombustible, corrosion resistant metal mesh. [2005 RLDC § 76.030.]
19.76.040 Access.
Driveways and new public roads shall meet the following requirements:
A. Driveways.
1. Driveways shall be developed to within 50 feet of all habitable structures and 150 feet of nonhabitable structures.
2. Driveways shall be constructed to meet all of the following minimum standards:
a. Width. Driveways shall be at least 12 feet wide in straight sections and at least 14 feet wide in all curves that have a centerline radius at any point less than 150 feet. It may be advisable to increase further the width of driveways in some curves to assure that emergency equipment remains on the developed surface throughout the entire turn.
b. Turning Dimensions. Driveway curves shall have a minimum curve radius of 48 feet. Driveway approaches to public roads shall have an inner radius of 20 feet in both directions.
c. Grade. Driveways shall comply with the following grade limitations:
[1] Driveway development that disturbs areas with slopes at or above 15 percent or that involves granitic soils requires an approved erosion control plan prepared by a registered engineer before disturbance. See Chapter 19.83 JCC (Erosion Control and Storm Drain Facilities).
[2] No portion of any driveway shall have grades that exceed 15 percent, except grades may increase to 18 percent for intervals of not more than 100 feet as long as there are no more than three 100-foot sections in excess of 15 percent per 1,000 feet of driveway.
[3] All areas within curves that have a centerline radius of less than 150 feet shall not exceed a 15 percent grade.
[4] Changes in grades within driveways shall not exceed one percent in three feet.
d. Clearances. Areas around driveways shall be cleared as follows:
[1] The area above the entire length and width of driveways shall be cleared and kept clear of all obstructions for a minimum vertical distance of 13 feet, six inches.
[2] A strip at least two feet wide along both sides of the prescribed width of the driveway, and for its entire length, shall be established to the standards for secondary safety zones in JCC 19.76.080(C)(2); provided, however, that the vegetation in these areas cannot exceed six feet in height.
e. Surfaces. Driveways shall be surfaced as follows:
[1] Driveways with slopes below 15 percent shall be constructed as follows:
[A] A base course of six inches to eight inches of pit run rock; and
[B] A leveling course of two inches to three inches of three-fourths inch minus angular gravel; and
[C] Compacted by proof-rolling the rocked and graveled courses with a fully loaded 10 cubic yard dump truck or other vehicle with equivalent weight; or
[D] Base and leveling courses and compaction standards for a restricted rural residential road when the driveway is paved with asphalt; or
[E] To standards different from the ones specified in subsection (A)(2)(e)[1][A] through [C] of this section, provided the alternative standards are supported by a driveway construction plan prepared by a registered engineer that contains a certification that the surface, as built, will support 50,000 pounds, provide adequate drainage and traction and prevent significant degradation or deterioration as a result of rain or freezing and thawing.
[2] Driveways on granitic soils or with slopes of 15 percent or greater shall be constructed to the surface standards specified in a driveway construction plan prepared by a registered engineer that contains a certification that the surface, as built, will support 50,000 pounds, provide adequate drainage and traction and prevent significant degradation or deterioration as a result of rain or freezing and thawing.
[3] In transitions from dirt, rock or gravel to hardened surfaces, the hardened surface shall be extended 25 feet on each end beyond the slope to minimize dig outs and other deterioration of the surface.
f. Structures. A structure or fill and culvert shall be provided to cross all live streams, ravines, gullies, irrigation ditches and similar features. These structures shall have the same width as the width required for the driveway at the structure or fill and culvert location. Bridges shall be certified by a registered engineer as being capable of supporting at least 50,000 pounds. Culverts shall be a minimum of 12 inches in diameter and shall be designed to carry American Association of State Highway and Transportation Officials HS-20 Loading.
g. Turnarounds. Driveways leading to structures or to water sources used for fire suppression shall terminate in a turnaround area that is surfaced consistent with the surface requirements for the connecting driveway and has a minimum inner radius of 27 feet and a minimum outer radius of 42 feet.
h. Turnouts. Driveways in excess of 600 feet shall have vehicle turnouts at a maximum spacing of every 400 feet. Turnouts at more frequent intervals may be advisable when conditions caused by steep grades, dense vegetation, and/or frequent curves create unsafe passage. Turnouts shall consist of a 12-foot-wide by 25-foot-long driving area immediately adjacent to the driveway. Turnouts shall be surfaced with the same surface as the adjoining driveway.
i. Gates. Gates on private driveways shall provide a clear opening of at least 12 feet on straight stretches and 14 feet on all curves. Gates must be set back at least 30 feet from the public road or highway to allow emergency vehicles to clear the roadway when stopped at the gate.
j. Maintenance. Driveways shall be maintained to these standards in order to assure the accessibility of property and to protect firefighters and other emergency personnel.
B. Public Roads. New public roads longer than 800 feet in length that are created by a land division pursuant to Division V of this title shall provide access for residents and emergency service personnel consistent with the following requirements:
1. Looped Roads. When it is both feasible and practical, new public roads shall connect to existing public maintained or nonmaintained roads to create a looped road system.
2. Emergency Access. When a looped road system cannot be achieved, and it is feasible and practical to do so, new public roads shall be developed with emergency access. Emergency access is easement access that lawfully connects a new public road to another public road, street plug, public usage road, way of necessity or service road under control of the United States Department of Agriculture or the Interior. An emergency access may be gated or temporarily blocked in compliance with the standards and procedures set forth in Josephine County Board of Commissioners Order No. 2001-13 (Gated Streets), or as otherwise approved by the fire authority having jurisdiction under the order.
3. Special Mitigation Measures. When it is not feasible or practical to develop new public roads with looped or emergency access as required above, then the tentative plan shall be reviewed using the modification of standards procedures contained in JCC 19.76.090. The Wildfire and Emergency Safety Standards Review Committee may develop a fire mitigation plan for the land division and for individual lots within the land division that offset, to the greatest extent feasible, the lack of looped or emergency access through other practical measures. [Amended by Planning Director, 10-28-16; 2005 RLDC § 76.040.]
19.76.050 Signs.
Address and direction signs shall be permanently posted and maintained at driveway entrances and at any subsequent driveway intersections so that they clearly and effectively direct approaching emergency traffic to structure locations. Signs shall be posted and kept visible to indicate the nature anwd location of water sources that can be used for fire suppression. Numbers or letters used in the signs shall be at least three inches high and consist of light reflective material. [2005 RLDC § 76.050.]
19.76.060 Fire protection service or on-site fire protection plan.
As a condition of a permit to develop, the owner shall provide proof of fire protection service or fire protection measures that meet one of the following options:
A. Fire Protection District. The property upon which a structure or structures are to be developed is located within a fire protection district and the district agrees in writing to cover the structures, or the property is not located within a fire district, but the owner has requested to be included in the district and the district agrees in writing to include the property within the district before the development of any structure begins; or
B. Contract Fire Protection. If the property cannot be located within a fire protection district, but fire protection service is available from a commercial fire service provider that is listed on the state fire marshal roster and the owner provides a contract for fire protection to cover the property before the development of any structure begins; or
C. On-Site Fire Protection Plan. If the options described in subsections (A) and (B) of this section are not achieved, the owner shall devise and implement a special on-site fire protection plan as a condition of the permit. The plan shall include measures such as on-site water storage, fire sprinkling systems, additional safety zones, the placement of structures in the most defensible locations, storage of on-site firefighting equipment, and any other practical and effective measures given the conditions at the site. The special on-site fire mitigation measures shall be reviewed and approved utilizing the modification of standards procedures contained in JCC 19.76.090. Note: In the forest zones, a dwelling shall be located in accordance with subsections (A) and (B) of this section and only (C) if residential fire protection is determined to be impracticable per OAR 660-006-0035. [2005 RLDC § 76.060.]
19.76.070 On-site water for fire protection.
On-site water sources required for fire protection pursuant to JCC 19.76.060(C) shall comply with the following requirements:
A. Water Source. Water sources shall meet one of the following requirements:
1. A pond, swimming pool, noncombustible storage tank, lake or a similar body of water that contains at least 4,000 gallons of water year round; or
2. A stream or spring having a continuous year-round flow of at least one cubic foot per second.
B. Authorization. The application shall include a written statement from the Oregon Water Resources Department verifying that permits or registrations required for any water diversion or storage are obtained or not required.
C. Access. Driveway access and a turnaround meeting the requirements of JCC 19.76.040(A)(2) shall be developed to within 10 feet of the water source.
D. Signs. Permanent signs meeting the requirements of JCC 19.76.050 shall be posted along the driveway to direct emergency vehicles to approved water sources. “No Parking” signs shall be posted and maintained to prevent interference with equipment attempting to gain access to such water sources. [2005 RLDC § 76.070.]
19.76.080 Vegetation mitigation.
A. Purpose. The purpose of this section is to establish and implement fire safety zones. A fire safety zone is an area in which fire hazard is mitigated by the reduction, removal or limitation of vegetative fuels around structures. Safety zones can also be enhanced by the selection and placement of special fire resistant landscaping.
1. Fire safety zones shall be established to reduce the risk to structures from advancing wildfire, the risk to residents and emergency personnel who may be evacuating or accessing the site during wildfire conditions, and the threat to surrounding neighborhoods from structure fires.
2. Fire safety zones shall not be imposed in streamside setbacks established in Chapter 19.72 JCC to protect riparian vegetation. The presence of protected riparian vegetation within a fire safety zone shall not require the relocation of a site proposed for a structure or the denial of a permit sought under this chapter.
B. Fire Safety Zones.
1. Purpose. A fire safety zone is a fuel break designed to slow the speed and intensity of fire to or from structures, and to create an area in which fire suppression operations may more safely and effectively occur.
2. Character. Fire safety zones shall be a natural or a human-made area where material capable of allowing fire to spread either does not exist or has been cleared, modified or treated in a way that significantly reduces the speed and intensity of fire to move to and from structures.
3. Types of Zones. There shall be two types of fire safety zones, designated as the primary safety zone and the secondary safety zone. In all cases the primary safety zone shall be developed for a distance of 50 feet in all directions from structures as measured along the ground from the farthest extension of the structure, to include attached carports, decks or eaves. A secondary safety zone shall be established around the primary safety zone for an additional 50 feet in all directions. On sites on which the slope abutting any structure exceeds 20 percent, the secondary safety zone shall extend an additional 50 feet in all directions.
C. Fuel Mitigation. Fuel mitigation within fire safety zones shall conform to all of the following requirements:
1. Primary Safety Zones.
a. Ground cover within the primary safety zone shall consist of one or more of the following conditions:
[1] An area of asphalt, bare soil, concrete, rock or other nonflammable material; or
[2] An area of dead grass cut to four inches or less, leaves, needles, twigs and other similar flammable materials, provided such materials do not create a continuous fuel bed and are at least four feet away from structures; or
[3] An area of low growing vegetation species such as green grass, ivy, succulents and other similar species; provided, that it is maintained in a green condition and substantially free of dead plant material.
b. Other vegetation within the primary safety zone shall consist of single specimens or isolated groupings of native trees and shrubs, and fire resistant ornamental trees, shrubs and other plants, provided that they are:
[1] Maintained in a green condition;
[2] Maintained substantially free of dead plant material;
[3] Pruned and maintained so that crowns are separated by a distance of 15 feet and limbs below eight feet in height are removed; and
[4] Pruned and maintained so that no limbs touch a structure, or overhang a roof or are within 15 feet of a chimney or stovepipe.
[5] Live fruit trees shall not be required to meet the requirements of subsections (C)(1)(b)[3] and [4] of this section.
c. Open firewood storage shall not occur within 30 feet from structures.
2. Secondary Safety Zones. Trees within the secondary safety zone shall be pruned and maintained so that trunks are separated by a distance of 15 feet and any branches below eight feet in height are removed. Live fruit trees shall not be required to meet these spacing and limbing requirements. Small trees, brush growing underneath the remaining trees and dead vegetation and other debris shall be removed.
3. Fire Resistant Plants. Characteristics and examples of appropriate landscape plants can be found in “Fire-Resistant Plants for Oregon Home Landscapes,” published in 2002 by Oregon State University Extension Service as Forest Resource Note No. 6. Additional information is available from firewise.org and other Internet sites.
4. Modification of Safety Zones. In the event a property owner is unable to meet the space requirements for primary or secondary safety zones because the proposed home site is too close to one or more property lines, it is the policy of this chapter to resolve space issues using the following priority of actions:
a. The home site shall be relocated to an alternative site that allows the space requirements to be met; or
b. If an alternative and qualifying home site is infeasible or impractical, the property owner shall obtain the necessary easement(s) from the adjoining property owner(s) that allows the needed safety zone area to be added, developed and maintained; or
c. If the actions described in subsections (C)(4)(a) and (b) of this section cannot be achieved, then the request to modify the space requirements shall be reviewed using the modification of standards procedures contained in JCC 19.76.090. [2005 RLDC § 76.080.]
19.76.090 Modification of standards.
A. Purpose. The purpose of this section is to establish procedures for the review and possible modification of certain wildfire and emergency safety standards.
B. Standards Subject to Modification. The standards that may be modified under this section are subject to the following rules:
1. General Standards Subject to Modification. The following wildfire and emergency safety standards may be modified under the authority of this section:
a. Site development and construction standards (JCC 19.76.030);
b. Special mitigation measures for public roads (JCC 19.76.040(B)(3));
c. On-site fire protection plan (JCC 19.76.060(C));
d. Vegetation mitigation (JCC 19.76.080).
2. Access Standards Subject to Modification.
a. Driveway Connects to Maintained Public Road. When a driveway wholly on the applicant’s property connects to a road that is maintained by the County or state, the access standards contained in JCC 19.76.040 may be modified, except that the provisions of JCC 19.76.040(A)(2)(c) (maximum driveway grade of 18 percent), JCC 19.76.040(A)(2)(e) (driveway surfaces), and JCC 19.76.040(A)(2)(f) (driveway structures) shall not be modified.
b. Driveway Connects to Private or Nonmaintained Public Access. When a driveway connects to an easement or public usage road, or the applicant’s property is served by a nonmaintained public road (or any combination of these circumstances), the Wildfire and Emergency Standards Review Committee is authorized to recommend modifications to any of the access standards contained in JCC 19.76.040.
C. Application Requirements. Modification of wildfire and emergency safety standards shall be initiated by site plan review application pursuant to the review procedures contained in Chapter 19.42 JCC (Site Plan Review). The Director shall develop wildfire and emergency safety standards modification application and mapping requirements consistent with the functions of this chapter and Chapter 19.42 JCC.
D. Wildfire and Emergency Safety Standards Review Committee. All requests to review and modify wildfire and emergency safety standards shall be reviewed by a special site plan review committee called the Wildfire and Emergency Safety Standards Review Committee.
1. Composition. The Director shall notify and involve other appropriate County departments, government agencies, political jurisdictions and fire protection districts. In addition, other wildfire and safety experts may be involved as the Director determines necessary or helpful to review applications.
2. Function. It is the function of the Committee to review all requests to modify the standards noted in subsection (B) of this section. The Committee may recommend or oppose proposed modifications. If the Committee recommends modification, it may also recommend other mitigation measures that are designed to offset risks resulting from modification. If the Committee recommends against modification, it shall explain why the modification should not occur. The Committee’s recommendation shall be in writing.
3. Authority. Action by the Committee shall not be considered a land use decision or final decision for appeal. The Director shall consider the recommendations of the Committee in making the final decision as specified in JCC 19.42.040(C). The Director, however, shall not modify any wildfire or safety standard without Committee review.
E. Variances. The wildfire and emergency safety standards contained in this chapter shall not be modified by procedures for variances (Chapter 19.44 JCC, Variances).
F. Forest Zones. The wildfire and emergency safety standards for new dwellings in forest zones, as established by OAR 660-006-0029 and 660-006-0035 shall not be made less restrictive using the procedures in this chapter or Chapter 19.44 JCC (Variances). [2005 RLDC § 76.090.]
19.76.100 Applications for dwellings in zones other than forest zones.
The development of new, remodeled, relocated or replaced dwellings in any zone other than the forest zones shall comply with the following application and approval procedures:
A. Application Requirements. Prior to issuance of a development permit for the development of dwellings in other zones, the owner shall submit to the Planning Office for review and approval:
1. A plot plan meeting the requirements of JCC 19.41.020(B)(3);
2. Proof of fire protection service meeting the requirements of JCC 19.76.060(A) or (B) (if fire protection service is not available, the application shall be subject to the requirements of subsection (C) of this section);
3. Proof of on-site water supply.
B. Certification of Compliance. Prior to obtaining a certificate of occupancy from the County Building and Safety Department, the owner(s) shall complete a certificate of compliance on forms provided by the Planning Office. The certificate of compliance shall certify, by the signature of all owners of record for the property, that all applicable wildfire and emergency safety standards required by this chapter have been satisfied. The Planning Director shall maintain the original certificate of compliance in the Planning Office file for the property.
C. Absence of Fire Protection Service. In the event that the lot or parcel cannot demonstrate proof of fire protection as required by subsection (A)(2) of this section, the owners shall submit an on-site fire protection plan as described in JCC 19.76.060(C). The plan shall be reviewed pursuant to JCC 19.76.090 (Modification of standards). [Amended by Planning Director, 10-28-16; 2005 RLDC § 76.100.]
