Memo DATE: 2/27/2018 TO: Planning Commission FROM: Brandon Goldman, Senior Planner RE: Development Standards for Wildfire Lands ordinance amendments SUMMARY General discussion regarding modification of the adopted Wildfire Lands boundary map, and potential amendments to the Development Standards for Wildfire Lands (Chapter 18.3.10.100) Currently requirements for Fire Prevention and control Plans, and Fuel Breaks, only apply to properties within the existing Wildfire Lands area. It is the recommendation of Ashland Fire & Rescue that all areas within the city limits be declared a wildfire lands, amending the current Wildfire Lands boundary as set forth in 1992. BACKGROUND th Ashland Fire and Rescue originally presented a proposal to the City Council on April 15, 2014 requesting staff prepare a modification of the Physical and Environmental Constraints Map to ds to incorporate the entire City (attached map). Such a map amendment is a legislative Land Use action requiring the approval of an ordinance, with public hearings before the Planning Commission and City Council. In review of the existing development standards for Wildfire Lands, Ashland Fire and Rescue identified a number of potential changes to the existing code to be considered as part of the legislative amendment process underway. Proposed code revisions would serve to both clarify the submittal requirements for a Fuel Prevention and Control Plan, as well as establish new requirements for the implementation of required fuel breaks not presently codified within the currently adopted Land Use Ordinance (18.3.10.100 attached). The Planning Commission discussed the expansion of the Wildfire Lands boundary at Study Sessions on June 24, 2014, February 24, 2015, November 24, 2015, and February 23, 2016. Following the Planning Commissions last study session the Mayor convened an ad-hoc wildfire hazard committee (comprised of City staff, representatives from the Tree, Planning, and Wildfire Mitigation Commissions). Department of Community Development Tel: 541-488-5305 51 Winburn Way Fax: 541-552-2050 Ashland, Oregon 97520 TTY: 800-735-2900 www.ashland.or.us Ashland Fire and Rescue, and the wildfire hazard committee, also worked with an organization called Community Planning Assistance for Wildfire (CPAW) to evaluate s risks and to provide s existing and proposed wildfire development standards. visited Ashland to inform their recommendations intended to ensure wildfire is considered alongside other community planning priorities. The CPAW report is attached to this memo. In consideration of the wildfire risk facing the community, the ad-hoc wildfire hazard committee is developing a multi-faceted approach to reducing risks throughout the City. This approach includes: creating a community information program where residents can review a new parcel based wildfire risk assessment map to determine and address their individual risk factors, establishing a voluntary fuels reduction program facilitated by the City, expanding the existing wildfire overlay zone to newly include all properties within the City, adopting by ordinance a prohibited flammable plant list, which would preclude such highly flammable plants from being newly planted within 30 feet of any structure within the City, adopting land use ordinance amendments that establish standards for fire prevention and control plans, and fuel management requirements, that are to be carried out in conjunction with new development activities within the City. Wildfire Development Standards The expansion of the Wildfire Lands boundary would have development implications for all properties within the City Limits that due to their inclusion they would become regulated under AMC Chapter 18.3.10.100 \[Development Standards for Wildfire Lands\]. A Fire Prevention and Control Plan would be required with applications to partition properties, subdivisions, or to obtain site review approval (commercial or multi-family developments) with the exception of Accessory Residential Units. A Fuel Break would be required of all properties obtaining building permits for new construction. New or re-roofed structures could not use combustible roofing material as defined by the Oregon Revised Specialty building code. The version of the ordinance presented to the Planning and Tree Commission at prior study sessions has been substantially modified to address vegetation management standards in consideration of the potential impacts upon small parcels within the City. Specifically a number of revisions to the draft fuel modification area standards aim to establish fuels reduction requirements that more clearly distinguish between the risk posed by highly flammable plants and trees and those shrubs and trees that are more fire resistant, as well as to provide flexibility to address specific site conditions. Trees that are fire resistant trees (e.g. Oak, Madrone): o eliminated, now it simply requires limbs not be in direct contact with the roof or Department of Community Development Tel: 541-488-5305 51 Winburn Way Fax: 541-552-2050 Ashland, Oregon 97520 TTY: 800-735-2900 www.ashland.or.us The separation between the canopies of fire resistant trees has been eliminated, o thereby allowing such trees to have interlocking canopies. Trees that are on the prohibited plant list (e.g. Fir, Pine): The previously separation between the tree canopy and o wildfire hazard committee and Fire recommendations. Plants identified on the proposed Prohibited Flammable Plant List, shall not be newly structure they are to maturity. Fire resistant shrubs and bushes have no separation requirement so could form hedges and privacy screens. The vertical clearance between the top of understory vegetation and the lowest tree limbs shall be at least three times the height of vegetation where either the tree or Flammable Plant list. If both the tree and the shrub are fire resistant, then no ladder fuel vertical clearance would be required. The prior draft prohibition of any combustible natural or manmade material within three feet of a structure. This provision has been amended to allow fire resistant shrubs and ground covers within this area. Plants listed on the prohibited flammable plant list would still be prohibited within this high risk area, which was increased to 5 feet of a structure. However, in the event the structure has a fire resistant exterior (i.e. stucco, brick, concrete block, metal siding, etc), then combustible material such as bark could be located within this area under a demonstration that it would not pose a risk. The requirement to complete fuel management within for the full extent of a property when a new building (sfr, mfr, commercial) is developed is still required, as was the case in the prior version of the ordinance. In the event an addition, deck, or detached accessory structure over 200 sq.ft. is to be built, the required fuel management area in this draft has been reduced to apply only in new construction, not the full extent of the property. The draft ordinance newly includes a mechanism to allow general fuel management area standards, and fire prevention and control plan requirements, to be waived or reduced if the Staff Advisor, in consultation with the Fire Code Official, provided it can be determined that the nature of the development proposed in the project application does not constitute an increased risk to the spread of wildfire. This section introduces more flexibility than was provided in the 2016 draft ordinance to consider the existing conditions on a case by case basis. Prohibited Flammable Plant List The proposed Prohibited Flammable Plant List is presented to identify which plants should not be newly planted, would need to be thinned, or potentially removed within a general fuel management area in conjunction with the issuance of a building permit. This limitation Department of Community Development Tel: 541-488-5305 51 Winburn Way Fax: 541-552-2050 Ashland, Oregon 97520 TTY: 800-735-2900 www.ashland.or.us regarding species that could be included in landscape plan would apply to construction activity that triggers the fuel management area requirements (18.3.10.100.B) and would have to be addressed on a required Fire Prevention and Control Plan. The prohibition on newly planting such highly flammable plants would apply city-wide, as codified the Public Health and Safety chapter (Ch..9) of the Municipal Code, if so approved by Council as a new policy. The draft Prohibited Flammable Plant List was reviewed by the conservation division, AFR, and the ad- hoc wildfire hazard committee. The revised list is attached. Next Steps The materials presented to the Planning Commission at this evenings study session remain a work in progress. This study session provides an opportunity for initial review and discussion in anticipation of another study session on this topic with the Planning Commission scheduled th for March 27, 2018. Following Study Sessions with the Tree Commission and City Council, a formal hearing on the proposed amendments is expected to be scheduled before the Planning Commission on June 12, 2018.

As part of this process, CPAW team members Molly Mowery and Kelly Johnston reviewed key draft planning documents under consideration by the City, including the Draft Development Standards for Wildfire Lands (Section 18.3.10.100, dated February 23, 2016), and the Draft Resolution Adopting the City of Ashland Fuel Break and Prohibited Plant List. This memo provides preliminary findings and recommendations for consideration by planning division and fire department staff. These findings are intended to facilitate additional discussion; any final recommendations to the City will be based on further discussion and information obtained during an anticipated site visit. For questions regarding this memo, contact: Molly Mowery, Wildfire Planning International, molly@wildfireplanning.com, 303-358-9589. Preliminary Findings and Recommendations 18.3.10.100 A. Requirements for Subdivisions, Performance Standards Developments, Site Design Review or Partitions A.3.c. It may not be necessary to show the location and dimensions of all structures upon adjoining properties located within 30 ft. of a shared property line in cases where lot sizes are large enough to have an independent defensible space. Instead, we recommend requiring Fire Prevention and Control Plans to show the location and dimensions of all structures within 30 ft. from the primary structure (including accessory structures and structures on neighboring lots within 30 ft.). A.3.d.vii. confusion. The City should consider setting thresholds that define this term in the document. applying subsections 3.d.i to 3.d.vii. to t,reframing subsection 3.d.viii to substitute the term for . This option allows for an assessment and plan development by a qualified professional which can account for ecosystem and other objectives on large tracts of land. CPAW Memo of Preliminary Findings and Recommendations to the City of Ashland January 10, 2017 Page 1 B. Requirements for Construction of All Structures B.1. as defined by the City, and consistent with the National Wildfire NWCG) definition, is a completely acceptable term, it may not be the most appropriate term may be interpreted by the public as significant vegetation removal, creating the image of a substantial vegetation. or removal of fuels to reduce the likelihood of ignition and/or to lessen potential damage and resistance to control (e.g., lopping, chipping, crushing, pil B.1.a. The City should consider not including a 200 sq. ft. threshold regarding new construction, additions and conversions, as any addition or new structure within 30 ft. is a hazard to the primary structure, unless mitigated. Alternatively, the City should retain the proposed language, but consider additional language requiring a structure less than 200 sq. ft. be constructed to fire resistant standards, including ignition resistant siding and Class B or better roofing and a horizontal combustible material free zone of five ft. from the furthest horizontal extension of the structure. This will minimize the impact of the new structure contributing to the current fuel complex hazard. B.2. General Fuel Break Requirements. Again, we agree with this definition of a fuel break, but are not confident that the current allowances for vegetation retention will result in the creation of fuel breaks. We therefore recommend using the which both are defined by the NWCG as likelihood of ignition and/or to lessen potential damage and resistance to control (e.g., lopping, B.2.a. Consider expanding this provision to include exceptions outside of water resource protection areas for cases when a dead or dying tree can provide ecological benefits. For example: dying vegetation shall be removed from the property, except when approved to be considered ecologically beneficial. B.2.b. In general, we recommend the City add not only provide positive guidance, but will also prevent the use of plants and trees that may have been inadvertently overlooked on the We also recommend that all existing vegetation within five ft. of a structure be removed (measured between the furthest horizontal extension of the structure and the closest horizontal 1 extension of the plant). This is based on current wildfire ignition science which establishes minimum distances for vegetation bordering a structure, including attachments. If compromises Њ This is based on scientific experiments and case studies conducted by National Institute of Science and Technology, USDA Forest Service and Insurance Institute of Business and Home Safety. CPAW Memo of Preliminary Findings and Recommendations to the City of Ashland January 10, 2017 Page 2 are made to reduce this distance, we recommend that the City consider retaining a five ft. non- - plants (or plants identified on the proposed ) to be no closer than three ft. from the closest part of the structure, if --combustib from grade to eaves (see B.2.c below). B.2.c . We recommend the City consistently usgnition-resistant,when referencing construction materials, to align with common definitions and provide definable thresholds (meeting testing requirements) on the products that are being used. As recommended above, we also suggest that the City consider expanding the three ft. border to a five ft. non-combustible border. Again, if compromises are made to reduce this distance, we recommend that the City consider retaining the five ft. non-combustible surface, while allowing Fire-plants (or plants ) to be no closer than three ft. from the ignition-- We also recommend the City consider requiring the removal, or not allowing the placement, of any shrubs within five ft. trees that are within 30 ft. of a window. 30 ft. of a window, unless it is a Significant tree, and/or can be pruned so that the crown base is five ft. above the roof deck. B.2.d. We recommend the City consider adjusting language to require existing Prohibited trees within 30 ft. of the structure be removed, with exceptions of those that are significant trees, or where --ns, we recommend that all retained Prohibited trees within 30 ft. be pruned to a minimum of five ft. above the roof deck or 1/3 of the tree height, whichever is less. B.2.e. We recommend the City consider changing this distance to a relative distance of crown size and fuel loading (i.e., crown bulk density) and therefore a relative distance to mitigate potential radiant heat energy and flame length produced by the individual crown. We further recommend that the City consider as similar approach for subsection B.2.e.i., where a group of group. B.2.n. The rationale behind this provision is unclear in the text. Is there additional information to add to support the distance of 130 ft.? This may be helpful to further clarify. B.3.Roofing. What are the requirements if the roof replacement does not occur within the five year timeframe (i.e., exceeds the five year period stated in the provision)? This may be helpful to further clarify. CPAW Memo of Preliminary Findings and Recommendations to the City of Ashland January 10, 2017 Page 3 Best Practices Compilation for Ashland, Oregon: Community Programs and Implementation Practices Across the West April 2017 Overview This document provides the City of Ashland with best practices from across the west. Community examples highlight successful mitigation programs, landscaping codes, WUI codes professional qualifications, which and related activities. Additional community examples are also available through the Community Planning Assistance for Wildfire website. Case Studies on WUI Code Adoption Process Wenatchee, Washington In 2015, the City of Wenatchee experienced the Sleepy Hollow fire, which burned 30 homes on the outskirts of town (due to direct flame impingement and embers) and multiple commercial warehouses in the urban downtown core (due to the transportation of embers from the burning structures).As part of the Fire Code, the City has a WUI Standard in place. The WUI Standard does delineate the City into two distinct zones, however, the standard does not fully capture the set of conditions that promotes the ignition and spread of fire through the WUI fuel complex (wildland and built fuels). current designation for the WUI is below: 3.36.010 Wildland-Urban Interface Zone Designation The code official shall have final authority in determining which properties shall be affected by exposure to large tracts of natural vegetation. Property and structures immediately adjacent to undeveloped land with natural vegetation without fuel breaks establish the interface line or primary zone and are subject to all of the provisions of this chapter. Property and structures located to the east, or the developed side, of the primary zone and within 1,500 feet of the interface line are included in the secondary zone. (Ord. 2011-13 § 1) While this designation delineates boundaries for enforcement within the WUI, it does not capture the true scope of the C experiences and risk information into account, the Community Planning Assistance for Wildfire (CPAW) team worked with the City to provide recommendations to improve its WUI approach. Included in the final recommendations was a priority recommendation for the City to redefine the WUI and implement a WUI risk assessment program (currently in the implementation stages) to better prepare for potential wildfire impacts in Wenatchee. As part of this, the CPAW team recommended that the entire City be identified as the WUI, with a re-defined Primary and Secondary Zone. The most stringent WUI Standards are recommended to apply to the Primary Zone, where structures will be potential exposed to radiant and convective heat transfer, as well as burning airborne embers. Less stringent standards are recommended to apply to the Secondary Zone, where structures are potentially exposed to localized radiant and convective heat, as well as short, medium and long range burning embers. (The recommendations to Wenatchee can be downloaded here.) Within the currently adopted Fire Code WUI Standards (3.36.160), Wenatchee provides the definition of defensible space, outlines the responsibilities of the land owner, and references the ICC International WUI Code and the NFPA 1144, Standard for Reducing Structure Ignition CPAW Community Best Practices for Ashland April 2017 Page 1 Hazards from Wildland Fire. The Code provides characteristics of fire resistant vegetation according to the Firewise website. The descriptions from the Wenatchee WUI Standards are listed below (note: CPAW also provided recommendations to this section; current language may change based on future revisions): (1) Growth with little or no accumulation of dead vegetation (either on the ground or standing upright. Although green, both juniper shrubs and arborvitae accumulate large amounts of dead material). (2) Nonresinous plants (willow, poplar or tulip trees). (3) Low volume of total vegetation (for example, a grass area as opposed to a forest or shrub-covered land). (4) Plants with high live fuel moisture (plants that contain a large amount of water in comparison to their dry weight). (5) Drought-tolerant plants (deeply rooted plants with thick, heavy leaves). (6) Stands without ladder fuels (plants without small, fine branches and limbs between the ground and the canopy of overtopping shrubs and trees). (7) Plants requiring little maintenance (slow-growing plants that, when maintained, require little care). (8) Plants with woody stems and branches that require prolonged heating to ignite. For reference on specific plants and their characteristics, see http://firewise.org. (Ord. 2011-13 § 1) Flagstaff, Arizona Located in a Ponderosa Pine forest, Flagstaff Arizona is subject to and familiar with wildland fires and the potential impacts on its community. Following a 1996 fire season, City leaders took action to mitigate against wildfire. Following ten years of education and various programs, the City adopted the WUI code in 2008. The code development and adoption success was a result of a two year public outreach process that familiarized the local stakeholders and residents with wildfire risk reduction measures. The City produced a Wildland-Urban Interface Code Adoption: How to avoid the agony document to International Fire Code and Wildland Urban Interface Code. Flagstaff also had steep slope and natural resource protection ordinances in place as part of a Resource Protection Overlay Zone. When the WUI code was adopted, language in the planning and zoning documents clearly identified the WUI code to supersede the resource protection documents as identified in Flagstaff Resource Protection Standards (10-50-90). Additional Appendix 5 (Additional Information). CPAW Community Best Practices for Ashland April 2017 Page 2 Home Ignition Zone: Incentivizing Property Mitigation Communities seeking to implement WUI codes and regulations often struggle with how to address existing development. Combining regulatory and voluntary approaches can help address this challenge by offering programs which incentivize defensible space and home retrofits. Two Colorado counties serve as examples: the REALFire program (Eagle County, CO) and the Wildfire Partners program (Boulder County, CO). Both counties have implemented regulations for future development in concert with voluntary programs which incentivize risk reduction practices and provide valuable homeowner education. Programs partner with fire departments, fire districts and other local stakeholders and private organizations to offer property assessments. Each program utilizes concept, introduced by Dr. Jack Cohen (USFS), and further incorporate science from in the Insurance Institute for Business and Home Safety (IBHS) to provide the following: An in-depth assessment of a home, property, and accessory structures and other attachments performed by a trained mitigation specialist. Landscaping guidance based on the Colorado State Forestry Service Firewise Guidelines. A detailed and customized report, including a mitigation checklist to guide the ns. A follow up site visit to verify completion of work. A certificate to acknowledge successful completion, which may also be shared with insurance providers to secure or renew coverage. Each program also takes advantage of the $2,500 tax deduction available for Colorado homeowners creating defensible space. Eagle County, CO Existing Regulations for New Construction Regulations in Eagle County are meant to reduce risk, provide a set of strategies to help minimize impact to adjoining properties, and provide firefighter access when wildfires do occur. When possible, development in high-risk locations is avoided altogether. use regulations include a section for Development in Areas Subject to Wildfire Hazards in the Eagle County (Section 4-430). This section is applicable to any application for a Special Use Permit, Subdivision or Planned Unit Development. It requires the submittal of a vegetation management plan, and includes detailed language on plan requirements, procedure and standards. The County development standards require: A wildfire hazard rating for a plat before any building permit is issued. A Vegetation Management Plan for new development be generated by a natural resource professional. Fire resistant materials for interior walls and ceilings with a one hour rating (e.g., thick gypsum board) along with a non-combustible exterior such as brick or mortar. Adequate defensible space around the structure. A water supply and access plan identifying adequate turn arounds and dual point access in new developments. CPAW Community Best Practices for Ashland April 2017 Page 3 REALFire® Program The REALFire® program was established by the Vail Board of Realtors® and Eagle County, Colorado. It uniquely engages Realtors in local wildfire risk reduction efforts by engaging their support and expertise in marketing and outreach with local members and other Realtors associations. Eagle County provides assessment data, program coordination and outreach with local fire protection districts. A home assessment app has also been generated based on home ignition zone best practices, which automatically generates a full property assessment report. Each completed assessment is automatically stored in a database for easy access and management of collected information. The program is funded through Eagle County, Vail Board of Realtors, several Homeowner Associations, and state and federal grants. Assessments were initially offered at $50 and will be offered at no cost during the 2017 calendar year. Homeowners who successfully complete their wildfire mitigation activities can obtain a wildfire certificate for their individual properties. This certification can be used to enhance real estate transactions by reassuring prospective buyers that wildfire risk reduction has been achieved. More information is available on the REALFire® website. Boulder County, CO Existing Regulations for New Construction In response to multiple wildfires affecting the Boulder County community, the County surveyed and mapped the WUI area to identify the extent of the wildfire hazard (further explanation found inthe County CWPP Pg.65). Over the course of several decades, the County initiated and revised development regulations for new development in the identified WUI hazard area to address: Defensible space practices for all new development Building material restrictions including roofing, siding, walls, and windows Site Development Standards/site plan reviews addressing site location, building construction and design, landscaping/defensible space/fuel management, access and water availability. current Wildfire Mitigation program is administered through the C Use Department. Prior to the issuance of a building or grading permit, a wildfire mitigation plan must be submitted to and approved by a County Wildfire Mitigation Specialist. The wildfire mitigation plan must include a site plan showing the location of structures and other improvements, extent of defensible space management zones, the location of a fire cistern, and a written narrative detailing the site location, construction design and materials, defensible space and forest management, driveway access for emergency vehicles, water supply and maintenance. Prior to a a foundation inspection, the majority of defensible space and forest management must be completed. Wildfire mitigation forms and publications for landowners are easily accessible online, and include guidance on defensible space, landscaping, building with ignition-resistant materials, fire sprinkler approval form, rock installation around structures, woody material disposal, and a wildfire mitigation timeline for the building permit application process. CPAW Community Best Practices for Ashland April 2017 Page 4 Wildfire Partners Program a template for communities to engage homeowners in the WUI. The program is run completely County, a $1.5 million grant from the Colorado Department of Natural Resources and a $1.25 have allowed the program to offer reduced assessment rates and financial awards to subsidize work being done by designated contractors or homeowner material costs. Through the partnerships with the insurance companies in the area, receiving a certificate can translate into reductions in insurance premiums and the renewal of insurance policies in wildfire risk areas. More information is available on the Wildfire Partners website. Language on "Qualified Professional" References To support the implementation of mitigation programs, communities may rely on qualified professionals to review, develop or submit plans. Examples include: Larimer County, Colorado , Section 3 Hazard Areas outlines the entire development process in identified hazard zones including professional qualifications, stating: All maps and reports required by this section must be prepared by or under the responsible direction of a duly qualified expert. Wildfire hazard analysis must be performed by a professional forester with at least two with wildfire hazards in the Rocky Mountain Region. Boulder County, Colorado In Article 3 Application Submittal Requirements, Section 203 Standards for Submittal Requirements of , necessary professional qualifications and details for hiring consultants are outlined: B. Professional Qualifications 1. A professional consultant may not be necessary for all applications. Only the following will require professional assistance. a. Improvement plans and reports for water supply, sanitation, drainage, utilities, soils, grading, roads, structures, and other civil engineering work must be certified by a registered Colorado Professional Engineer b. All documents containing land survey descriptions must be certified by a registered Colorado Professional Land Surveyor c. Geology reports shall be prepared by either a member of the American Institute of Professional Geologists, a member of the Association of Engineering Geologists, or an individual registered as a geologist by a state CPAW Community Best Practices for Ashland April 2017 Page 5 d. Wildlife impact reports, where required, shall be prepared by an approved wildlife expert retained by the County Parks and Open Space Department and paid for by the applicant 2. All data and plans submitted for review must show the qualifications of the individual in charge of the work. C. Consultants 1.If the County does not have qualified staff to review certain elements of a proposal or referral agencies are not able to adequately advise the County regarding certain elements of a proposal, the Board of County Commissioners may authorize the review be performed by a consultant engaged or approved by the Land Use Director after discussion with the applicant. 2. A referral agency may impose a fee for the review of the development proposal. 3. The costs of either review are the responsibility of the applicant. No hearings will be held if the consultants fee has not been paid CPAW Community Best Practices for Ashland April 2017 Page 6 Appendix A: Additional Examples and Resources for Landscaping Regulations Community Examples Kittitas County, Washington Kittitas County adopts the most current ICC WUI code along with Appendix B Vegetation Management Plan in the Kittitas County Code- Title 20- Fire and Life Safety. The county also designated all unincorporated areas to be within the WUI. Further Explanation of Defensible Space is located on their Building Permit Submittal. Ruidoso, New Mexico Ruidoso was heavily affected by the Little Bear fire in 2012. The City took it upon themselves to mitigate wildfire risk to the community by integrating multiple ordinances, including a comprehensive description of proper defensible space, into their city code. While some of the language would need to be revised due to differences in fuels, Standards (42-80) provides an excellent example of what can be done when implementing wildfire landscaping ordinances. Section 42-80 A3 addresses vacant lots and absentee land owners and is measured based on the risk to neighboring properties. The City will notify the landowner of the situation and give a proper timeline to correct the issue. If not corrected a series of escalating fines are imposed until the problem is corrected. San Diego, California San Diego California may be the most regulated area in the country for defensible space landscaping regulations. Section 142.0412 Brush Management is a helpful example of defensible space being implemented into landscaping regulations. The code gives the fire chief specific authority to regulate brush management in addition to overriding specific environmental regulations when necessary. The 100ft defensible space area is broken down into Zone 1 and Zone 2 with extremely detailed outlines for necessary actions in both. These zones and actions could easily be manipulated for local use.

CPAW Community Best Practices for Ashland April 2017 Page 8 Memo DATE:February 27, 2018 TO:Ashland Planning Commission FROM:Maria Harris,Planning Manager RE:Accessory Residential Unit Draft Code Revisions The PlanningCommission discussedproviding more flexibility for accessory residential units(ARU) in the single-family zones at theAugust 22, 2017, October 24, 2017 and November 28, 2017 study sessions. In summary, the draft revisions to the ARU standards would allow units less than 500 square feet in size that are within or attached to the primary residence as an outright permitted use. As an outright permitted use,the ARUs would be exempt from the planning application process for Site Design Review. This means a property owner could convert existing floor area or construct an ARU with a building permit. Site Design Review approval is normally required for any development that includes two or more dwellings on one tax lot. The outright permitted ARUs are covered in a new “exemption” section in 18.2.3.040.A. The ARUs would be allowed in the R-1, R-1-3.5, NN and NM zones. These small ARUs would not be required to have additional off-street parkingif there is on-street parking within 200 feet of the property. The ARUs could either be built as part of new construction or added to a primary residence at a later date. The attacheddraft incorporates revisionswith notations that were discussed at the November 28, 2017 study session.Revisions without notations are either unchanged from the last draft or are housekeeping strikeout text is deletedunderline text is new (or edits and corrections.Grey text is unchanged,and moved) –these changes are shown in relation to the ordinance that is currently in place. The revisions in this draft include the following items. Exemption Section 18.2.3.040.A –In the previous draft, the exemption was included in the Site DesignReview chapter. The exemption section was moved to the ARU section for clarity and continues to be cross-referenced in the Site Design Review chapter. Off-Street Parking and Driveway Width 18.2.3.040.A.5 –In order for an ARU to be outright permitted and exempt from the planning applicationprocess, a requirement was added that the property have the required two off-street parking spaces for a single-family home and a minimum driveway width of nine feet. Page 2of 2 On-Street Parking 18.2.3.040.A.6 –Again, in order for an ARU to be outright permitted, a requirement was added that on-street parking is available on at least one side of the street within 200 feet of the property. Density 18.2.3.040.B.2 –The existing requirement that ARUs are counted in subdivision density was eliminated. Door and Balcony Placement – 18.2.3.040.B. 6 and 7Staff suggested two new design standards for ARUs regarding front door placement and second story window, door and balcony placement. These were moved from the Site Design Review standards to the ARU standards section. In addition, two changes were made to 18.2.3.040.B.7. First, the previous requirement that windows on asecond-story ARUareoriented to the interior of the property was removed so that it only applies to second story doors and balconies. Second, clarification was added for the meaning of orientation toward the interior of the property. RR Zone Requirements 18.2.3.040.C –The existing requirements that ARUs are located on slopes less than 25 percent and the requirements tohave an improved City street were deleted. Normal and North Mountain Overlays 18.3.4 and 18.3.5 –These zones allow ARUs and were included in the attached draft. The use language was added for consistency in the overlay chapters as well as reformatting the use table in the Normal Neighborhood district.The outright permitted ARUs are included in both of the overlays. Parking Ratios 18.4.3.040–The ARU parking standard is changed to match the existing cottage housing standard. The outright permitted ARUs are not required to provide off-street parking.

There are four Land Use Designation Overlays zones within the Normal Accessory Residential Units Revisions,February 27, 2018 Page 3 Neighborhood Plan are intended to accommodate a variety of housing opportunities, preserve natural areas and provide open space. 1.Plan NN-1-5 zone.The use regulations and development standards are intended to create, maintain and promote single-dwelling neighborhood character. A variety of housing types are allowed, in addition to the detached single dwelling. Development standards that are largely the same as those for single dwellings ensure that the overall image and character of the single- dwelling neighborhood is maintained. 2.Plan NN-1-3.5 zone. The use regulations and development standards are intended to create, maintain and promote single-dwelling neighborhood character. A variety of housing types are allowed including multiple compact attachedand/or detached dwellings. Dwellings may be grouped around common open space promoting a scale and character compatible with single family homes. Development standards that are largely the same as those for single dwellings ensure that the overall image and character of the single-dwelling neighborhood is maintained. 3. Plan NN-1-3.5-C zone.The use regulations and development standards are intended to provide housing opportunities for individual households through development of multiple compact attached and/or detached dwellings with the added allowance for neighborhood- serving commercial mixed-uses so that many of the activities of daily living can occur within the Normal Neighborhood. The public streets within the vicinity of the NN-1-3.5-C overlay are to provide sufficient on-street parking to accommodate ground floor neighborhood business uses. 4. Plan NN-2 zone. The use regulations and development standards are intended to create and maintain a range of housing choices, including multi-family housing within the context of the residential character of the NormalNeighborhood Plan. B.Normal Neighborhood Plan Residential Building Types.The development standards for the Normal Neighborhood Plan will preserve neighborhood character by incorporating four distinct land use overlay areas with different concentrations of varying housing types. 1.Single Dwelling Residential Unit.A Single Dwelling Residential Unit is a detached residential building that contains a single dwelling with self-contained living facilities on one lot. It is separated from adjacent dwellings by private open space in the form of side yards and backyards, and set back from the public street or common green by a front yard. Auto parking is generally on the same lot in a garage,carport, or uncovered area. The garage may be detached or attached to the dwelling structure. 2.Accessory Residential Unit. An Accessory Residential Unit is a secondary dwelling unit on a lot, either attached to the single-family dwelling or in a detached building located on the same lot with a single-family dwelling, and having an independent means of entry. 3.Double Dwelling Residential Unit(Duplex). A Double Dwelling Residential Unit is a residential building that contains two dwellings located on a single lot, each with self-contained living facilities. Double Dwelling Residential Units must share a common wall or a common floor/ ceiling and are similar to a Single Dwelling Unit in appearance, height, massing and lot placement. 4.Attached Residential Unit. (Townhome, Row house) An Attached Residential Unit is single dwelling located on an individual lot which is attached along one or both sidewalls to an adjacent dwelling unit. Private open space may take the form of front yards, backyards, or upper level terraces. The dwelling unit may be set back from the public street or common green by a front yard. Accessory Residential Units Revisions,February 27, 2018 Page 4 5.Clustered Residential Units -Pedestrian-Oriented.Pedestrian-Oriented Clustered Residential Units are multiple dwellings grouped around common open space that promote a scale and character compatible with single family homes. Units are typically arranged around a central common green under communal ownership. Auto parking is generally grouped in a shared surface area or areas. 6.Multiple Dwelling Residential Unit.Multiple Dwelling Residential Units are multiple dwellings that occupy a single building or multiple buildings on a single lot. Dwellings may take the form of condominiums or apartments. Auto parking is generally provided in a shared parking area or structured parking facility. 7.Cottage Housing. \[Reserved\] C.General Use Regulations.Uses and their accessory uses are permitted, special permitted or conditional uses in the Normal Neighborhood Plan area as listed in the Land Use Table.

For new multi-family residential developments, careful design considerations must be made to assure that the development is compatible with the surrounding neighborhood. For example, the use of earth tone colors and wood siding will blend a development into an area rather than causing contrast through the use of overwhelming colors and concrete block walls. 1.Crime Prevention and Defensible Space. a.Parking Layout. Parking for residents should be located so that distances to dwellings are minimized. However, avoid designs where parking areas are immediately abutting dwelling units because there is little or no transition from public to private areas. Parking areas should be easily visible from adjacent areas and windows. b.Orientation of Windows. Windows should be located so that vulnerable areas can be easily surveyed by residents. c.Service and Laundry Areas. Service and laundry areas should be located so that they can be easily observed by others. Windows and lighting should be incorporated to assure surveillance opportunities. Mail boxes should not be located in dark alcoves out of sight. Barriers to police surveillance such as tall shrubs and fences should be avoided. d.Hardware. Reliance solely upon security hardware in lieu ofother alternatives is discouraged. e.Lighting. Site development should utilize lighting prudently. More lighting does not necessarily mean better security. Lighting should be oriented so that areas vulnerable to crime are accented. f.Landscaping. Plant materials such as high shrubs should be placed so that surveillance of semi-public and semi-private areas is not blocked. Thorny shrubs will discourage crime activity. Low shrubs and canopy trees will allow surveillance, hence, reduce the potential for crime. Commented \[MH18\]: Moved below under standards – see “I” B.Applicability.Except as otherwise required by an overlay zone or plan district, the following standards apply to residential development pursuant to section 18.5.2.020. See conceptual site plan of multi-family development in Figure 18.4.2.030. 1.Accessory Residential Units.Unlessexempted from Site Design Review in 18.2.3.040.A,only the following standards in Chapter 18.4.2apply to accessory Commented \[MH19\]: This was suggested at the 11/28/2017 PC study session. residential units: building orientation requirements in 18.4.2.030.C, garage requirements in 18.4.2.030.D,and building materials in 18.4.2.030.E.If an accessory residential unit is located in the Historic District overlay, the standards Accessory Residential Units Revisions,February 27, 2018 Page 10 in 18.4.2.050also apply. C.Building Orientation.Residential buildings that are subject to the provisions of this chapter shall conform to all of the following standards. See also, solar orientation standards in section 18.4.8.050. 1.Building Orientation to Street.Dwelling units shall have their primary orientation toward a street. Where residential buildings are located within 20 feet of astreet, they shall have a primary entrance opening toward the street and connected to the right-of-way via an approved walkway. 2.Limitation on Parking Between Primary Entrance and Street.Automobile circulation or off-street parking is not allowed between the building and the street. Parking areas shall be located behind buildings, or on one or both sides. 3.Build-to Line.Where a new building is proposed in a zone that requires a build-to line or maximum front setback yard, except as otherwise required for clear vision at intersections, the building shall comply with the build-to line standard. D.Garages. The following standards apply to garages, carports, canopies, and other permanent and temporary structures used for parking or storing vehicles, including those parking and vehicle storage structures accessory to detached single-family dwellings. The standards are intended to balance residents’ desire for a convenient, safe, and private vehicle access to their homes with the public interest in maintaining safe and aesthetically pleasing streetscapes. The standards therefore promote pedestrian safety and visibility of public ways, while addressing aesthetic concerns associated with street-facing garages. For the purpose of this subsection, a garage opening is considered to be facing a street where the opening is parallel to or within 45 degrees of the street right-of-way line. 1.Alleys and Shared Drives.Where a lot abuts a rear or side alley, or a shared driveway, including flag drives, the garage or carport opening(s) for that dwelling shall orient to the alley or shared drive, as applicable, and not a street. 2.Setback for Garage Opening Facing Street.The minimum setback for a garage (or carport) opening facing a street is 20 feet. This provision does not apply to alleys. E.Building Materials.Building materials and paint colors should be compatible with the surrounding area. Very bright primary or neon-type paint colors, which attract attention to the building or use, are unacceptable. F.Streetscape.One street tree chosen from the street tree list shall be placed for each 30 feet of frontage for that portion of the development fronting the street pursuant to subsection 18.4.4.030.E. G.Landscaping and Recycle/Refuse Disposal Areas.Landscaping and recycle/refuse disposal areas shall be provided pursuant to chapter 18.4.4. H.Open Space.Residential developments that are subject to the provisions of this chapter shall conform to all of the following standards. 1.Recreation Area. An area equal to at least eight percent of the lot area shall be dedicated to open space for recreational use by the tenants of the development. 2.Surfacing.Areas covered by shrubs, bark mulch, and other ground covers that do not Accessory Residential Units Revisions,February 27, 2018 Page 11 provide suitable surface for human use may not be counted towards this requirement. 3.Decks and Patios.Decks, patios, and similar areas are eligible for open space. 4.Play Areas. Play areas for children are required for projects of greater than 20 units that are designed to includefamilies. Play areas are eligible for open space. Crime Prevention and Defensible Space. I. 1.Parking Layout. Parking for residents should be located so that distances to dwellings are minimized. However, avoid designs where parking areas are immediatelyabutting dwelling units because there is little or no transition from public to private areas. Parking areas should be easily visible from adjacent areas and windows. 2.Orientation of Windows. Windows should be located so that vulnerable areas can be easily surveyed by residents. 3.Service and Laundry Areas. Service and laundry areas should be located so that they can be easily observed by others. Windows and lighting should be incorporated to assure surveillance opportunities. Mail boxes should not be located in dark alcoves out of sight. Barriers to police surveillance such as tall shrubs and fences should be avoided. 4.Hardware. Reliance solely upon security hardware in lieu of other alternatives is discouraged. 5.Lighting. Site development should utilize lighting prudently. More lighting does not necessarily mean better security. Lighting should be oriented so that areas vulnerable to crime are accented. 6.Landscaping.
