Vos Caudill, Pitkin County, CO ADMINISTRATIVE DECISION OF THE COMMUNITY DEVELOPMENT DIRECTOR OF PITKIN COUNTY, COLORADO, APPROVING THE FELDMAN ACTIVITY ENVELOPE AND SITE PLAN REVIEW, SPECIAL REVIEW AND GMQS EXEMPTION FOR A CARETAKER DWELLING UNIT Administrative Decision Nof�,& -2013 RECITALS I ) Nathan Feldman (hereafter "Applicant ") has applied to the Community Development Director of Pitkin County (hereafter "Director ") to establish an Activity Envelope to encompass all site development, and obtain Site Plan review approval for a new single family residence, caretaker dwelling unit, and other associated development. 2) The property is located at 101 Cherokee Lane adjacent to the Swiss Village Tracts and Avalanche Ranch, and is more specifically described in Exhibit A. 3) The parcel contains 10.73 acres. The lower portion of the parcel where development is proposed is within the AR -10 zone district; the upper portion is within the RS -30 zone district. There are two existing structures on the property that were constructed by the prior owner without land use approvals or building permits; these structures will be removed. 4) The Director finds that the request complies with the applicable provisions of the Land Use Code ( "Code "), as follows: A) There is a mapped potential avalanche hazard area on the property. Art Mears, P.E., Avalanche - Control Engineer, identified blue and red avalanche hazard zones on the property and determined that the main residence avoids the blue and red avalanche hazard zones. The originally proposed location for the caretaker dwelling unit was within the blue zone, but the unit has been relocated adjacent to the residence in order to avoid the blue zone. Therefore, the residence and caretaker dwelling unit comply with Sec. 7- 20 -50(a) by avoiding the red and blue avalanche hazard zones. B) There is a drainage channel that flows from west to east through the northeastern portion of the property. Debris flow events may occur within the channel. Yeh and Associates, Inc. assert that debris flows will not affect the proposed building site or the driveway. Therefore, the residence and caretaker dwelling unit comply with Sec. 7- 20 -50(d) by avoiding the area affected by the debris flow. The area on the east side of Cherokee Lane could be affected by debris flows; a landscape envelope is proposed in this area to accommodate a lawn, but no other development is proposed in this area. C) There are two potential rockfall sources above the building site. Yeh and Associates Inc. assert that the rockfall hazard at the primary building site (residence and caretaker dwelling unit) is negligible and does not require mitigation. Yeh evaluated a secondary site below the proposed residence and determined that there was a low rockfall hazard at that site. No structures are proposed in this area in compliance with Sec. 7- 20 -50(c) of the Code, which prohibits development in rockfall areas. A landscape envelope is proposed in this area for a lawn, but no other development is proposed in this area. D) The Colorado Geological Survey concurs with the analysis and recommendations made by Yeh and Mears. E) There is a blue line stream that runs from west to east through the northeastern portion of the property. The building envelope for the residence and caretaker dwelling unit comply with the Administrative Decision No6&-2013 Page 2 required 100' setback from the high water line. An access envelope along the existing driveway encroaches into the 100' setback, as does a landscape envelope below the driveway. Sec. 7-20 - 80(a) allows for roads and similar facilities within the 100' setback, "upon a finding that there is no feasible alternative location and that any adverse impacts will be mitigated..." There is no feasible alternative location for the driveway and the Applicant will mitigate any impacts. F) The wildfire hazard is rated as severe, and can be mitigated pursuant to the provisions of Sec. 7-20 - 60(c) of the Code. G) The activity envelope primarily contains slopes of less than 30 %. Slopes in excess of 30% within the envelope are man -made in association with the prior development of the site and are anomalies in an otherwise continuous slope of less than 30 %. The Code permits development in these areas of slopes in excess of 30 %, pursuant to Sec. 70- 20- 20(c)(3). H) The parcel is within mapped elk winter range. The redevelopment of the site will have minimal additional impacts on wildlife. 1) The site is visible from Highway 133. The development complies with the Scenic View Protection Area criteria in Sec. 7- 20- 120(d) of the Code. The residence and caretaker dwelling unit do not break a ridgeline; are located on the lowest portion of the site; and avoid steeper slopes to the west. The residence and caretaker dwelling unit are sited at a substantial distance from the highway and will be added to a viewplane that already includes existing residences in Swiss Village and Crystal River Estates. The mass is reduced by detaching the caretaker dwelling unit, and utilizing pitched roof and porch elements and dormers. J) The proposed ground- mounted solar energy collectors comply with Sec. 4- 30 -50(h) of the Code. The solar energy collectors will be used primarily for on -site purposes, and will not protrude above a ridgeline or be visible from any surrounding properties. K) The caretaker dwelling unit complies with the applicable provisions of the Code, including Sec. 4- 20-50(e), use specific standards for Caretaker Dwelling Units; Sec. 2- 30- 30(h), Special Review criteria; and Sec. 6- 30- 40(c), GMQS exemption for a caretaker dwelling unit. APPROVED by the Director, subject to the following conditions, which shall run with the land and be binding on all successors in interest: 1. The Applicant shall adhere to all material representations made in the application and shall consider those representations to be conditions of approval, unless amended by other conditions. 2. The property is exempt from growth management for up to 5,750 square feet of floor area. The floor area of the caretaker dwelling unit shall be included in the total allowed floor area for the lot. 3. Prior to submission of any building permit applications, the Applicant shall be required to submit for approval by the County Attorney and Community Development a Site Plan with Activity Envelope in accordance with Land Use Code Section 2- 30 -20(g) and Application Manual Section 2.1.12. The above referenced approvals shall be a condition precedent to finalization and recordation of them. The Site Plan shall be amended as follows, prior to submission for recordation: A. The caretaker dwelling unit shall be moved adjacent to the north side of the residence and the portion of the building envelope that encompassed the originally proposed caretaker dwelling unit shall be eliminated B. The proposed landscape envelope and "construction access" above the residence shall be removed, since it is no longer needed for access to caretaker dwelling unit. C. The building envelope for the residence and caretaker dwelling unit and the utility envelope for the solar panels shall be revised to avoid the blue avalanche hazard area. Administrative Decision NoaA_2013 Page 3 4. With the building permit applications for the residence and caretaker dwelling unit, the Applicant shall: A. Provide proof of an adequate water supply (in terms of quantity and availability) for domestic and fire protection purposes for two dwellings, and for irrigation purposes, if applicable. Water supply for fire- fighting is available at the northern edge of the lot in the Crystal River Estates Subdivision, therefore, the Fire Marshal has not required an on -site supply. B. Submit a drainage and erosion control plan for review and approval by Planning/Zoning. If the development disturbs one (1) acre or more, the Applicant shall apply for and obtain a State Stormwater Permit. All historic and natural drainage patterns shall be maintained. C. Submit a large scale construction management plan for review and approval by Planning/Zoning. D. Complete a fireplace /woodstove registration form with the Community Development Department, if necessary. E. Submit a tree mitigation plan for the removal of trees larger than 6" DBH. Diseased trees do not require mitigation; a certified arborist must evaluate the trees to verify. F. Submit a landscaping plan. G. Submit a detailed revegetation plan for disturbed areas with appropriate seed mixes. H. Submit a lighting plan. 1. Submit a report from an engineer licensed in the State of Colorado that addresses the slopes in excess of 30% within the activity envelope to be disturbed during construction and demonstrates that the ground surface of these slopes is not prone to instability and that the proposed re- grading will not cause greater instability or increase the potential for slope failure along those disturbed slopes. 5. Prior to issuance of the building permit applications for residence and caretaker dwelling unit, the Applicant shall: A. Pay the applicable road and employee housing impact fees. B. Obtain an Access Permit for improvements to the existing driveway. The width of the driveway shall be increased to a minimum of 16' in order to maintain the existing grades in excess of 12 %. The Carbondale Rural Fire Protection District will not require a turnaround on the property, as fire personnel can access the residence from Cherokee Lane. C. Obtain an On -Site Wastewater Treatment System ( "OWTS ") Construction Permit application from Environmental Health. 6. Areas disturbed by construction shall be re- vegetated within one growing season of the project's completion. No development in excess of 30" above or below natural grade shall occur within the setbacks of the parcel, with the exception of driveways and associated retaining walls of up to 6' above or below natural grade and fencing. Landscaping in the form of berms within the setbacks shall not exceed four feet from the most restrictive grade. Any development located within setbacks mandated by County zoning regulations that does not comply with these restrictions shall require a variance from the Board of Adjustment. Approval of an activity envelope within such setbacks does not assure approval of a variance. 8. The exterior of the structures shall utilize indigenous earth tone materials or colors and the roofs shall have a non - reflective color or composition. Reflective roof materials shall not be used unless the materials are treated prior to installation to eliminate reflectivity, with the exception of materials Administrative Decision No& -2013 Page 4 associated with solar or photovoltaic equipment. Driveway lighting is prohibited and all other lighting shall comply with the lighting code. 9. The solar energy collectors and other ancillary development (racking assembly, balancing system, utility boxes, etc.) shall have a "matte" finish or be of a non - reflective material /color. The collectors shall not exceed 12' in height. 10. The Applicant shall comply with the following standards for Development in a Severe Wildfire Hazard Area: A. Defensible Space: The area around all buildings /structures, limited by property boundaries that may limit a property owner's ability to comply with this section, shall incorporate landscaping with wildfire defensible space considerations as follows (note: actual vegetation manipulation to meet these conditions may not be necessary where the natural vegetation patterns have already fulfilled these conditions): 1) Brush, debris and non - ornamental vegetation shall be removed and not replaced within a 10' perimeter around all structures. Grasses, forbs and irrigated ornamentals are allowed within this perimeter, as long as they are not brushy or coniferous. 2) Clumps of brush up to a 60' perimeter around all structures (or to lot boundaries) shall be thinned to 60% of the original canopy, leaving approximately 40% of the original brush canopy cover. Maximum diameter of the remaining clumps shall be % the height of the fuel. All measurements shall be from the edges of the crowns of the fuel. Shrubs shall be cut at the surface, and cut material shall be removed. Grubbing out of stumps is not necessary. Re- sprouting will occur, but fuel moistures will be high and would reduce fire hazards. No remaining clumps should be larger than approximately 25' in diameter. Thinning can be done in an aesthetically pleasing manner and heavier thinning should occur nearer to and below the structures. Re- sprouting shrubs will likely need to be re- thinned within 10 years. 3) No conifers may be within 20' of structures, and no conifers shall be planted below (down slope) of the structures. Tree crown separation shall be a minimum of 20', except for aspen trees, for which a tree crown separation is not required. 4) No branches shall be within 15' of a chimney and no branches shall be within 15' of the structures. 5) All deadfall and dead branches on shrubs shall be removed up to a 100' perimeter from all structures (or to lot boundaries). 6) No flammable mulches shall be placed within 2' of any structure. 7) Installed or native landscaping within 20' of any structures should not contain any brushy species; only grasses or forbs are allowed. Aspen trees are allowed near the structures, as long as they are not within 10' of the structure, and are kept limbed to 10' (unless the trees are less than 10' tall). No trees of any species may be within 15' of any window. 8) No conifers are allowed within 15' of the driveway. Remove all deadfall within 25' on the downhill side of the driveway. Remove 50% of the canopy of shrubs within 15' on either side of the driveway. All understory shrubs must be cut to the ground surface. 9) Low vegetation (grasses, forbs and low shrubs) shall be kept mowed to less than 6" within at least 10' on either side of the driveway during the summer. 10) The applicant shall be responsible for the continued maintenance of the defensible space vegetation requirements.

The property is accessed from Cherokee Lane, a private road that intersects with Highway 133 between Carbondale and Redstone. As shown on the vicinity map, there are many other residences located on much smaller tracts on the land surrounding the subject property. The applicant has not found any documents indicating that the subject property has gone through any Pitkin County land use review process. Nevertheless, there are two small structures on the property and an existing driveway in place. The structures include a small rustic cabin and a very small shed, both of which were put there by the prior owner of the property. The applicant has not found any evidence that either of these structures was built pursuant to a valid County building permit. This may not be relevant as the applicant does not plan to keep either of these structures as part of the site plan for the property. The applicant has prepared an Activity Envelope Site Plan for the property. The drawing on the cover sheet shows the entire boundary of the property while the drawing on the second sheet focuses on the lower portion of the property only, where the proposed activity envelopes would be located. The overall drawing shows that the property is nearly rectangular in shape. It consists of three basic areas, as follows: • The upper portion of the property (above elevation 6,950) is a relatively steep hillside, with continuous slopes in excess of thirty percent. This area is covered with brush and includes a number of significant natural features, including a drainage ravine that flows through the northern portion of the property and a rock outcropping that is a potential source of rockfall in the area. These geologic features have been studied by the applicant and the potentially hazardous areas of the property have been excluded from the proposed building envelope. • The lower portion of the property that is on the west side of Cherokee Lane is generally much less steep than the upper portion of the property. There are a couple of minor slope anomalies in this area due to the prior installation of the driveway but generally slopes are less than 30 %. Vegetation is somewhat more broken up in this area due to the presence of man -made improvements that resulted in the removal of brush. The cabin and shed are both located in this area. • There is also a small portion of the property (0.54 acres) that is located on the east side of Cherokee Lane. This area is also not steep and it contains an open area that is not covered by brush. However, studies performed of this area indicate it has the potential to be impacted by mud flows from the drainage ravine. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 3 000006 The second sheet shows the configuration of the proposed activity envelopes and the location of the planned improvements on the parcel. A 20' wide access envelope is shown along the driveway. The existing driveway is only about 12' wide and has steep sections with grades that exceed 12 %. The applicant conducted an on -site meeting with Bill Gavette of the Carbondale and Rural Fire Protection District to review options for improvements to the road. He stated that it was the District's preference that the driveway be widened in its current linear configuration rather than trying to put some curves in the drive that would make it less steep. The applicant has submitted a preliminary driveway plan showing the improvements proposed to the driveway and will work with the Fire District on the precise width and alignment for the improved driveway. The proposed new cabin would be in the center of the activity envelopes, below where the existing cabin is located. It is anticipated that this simple log cabin will be approximately 3,500 sq. ft. in size and will contain 2 bedrooms. A small 1 bedroom caretaker dwelling unit (approximately 525 sq. ft.) is also planned on a flat spot just above the existing cabin. Additional envelopes for accessory activities are also proposed, as follows: Several landscape areas are shown, one below the house, where the applicant would have a small yard with a sitting area and fire pit, and the other where the applicant would plan to install Aspen trees and other "wet" vegetation to replace some of the brush and other "dry" vegetation that must be removed to mitigate for the property's severe wildfire hazard designation. The applicant has also shown a utility envelope on the portion of the parcel to the east side of Cherokee Lane. This would be where the leach field would be located. This location was chosen to be sufficiently distant from the existing well, which is located below the proposed cabin site. It is also relatively flat, making it suitable for the leach field. The applicant also plans to install ground mounted solar energy collectors in the envelope shown to the west of /just below the house. This location will ensure that the collectors will be hidden from view from any surrounding properties. The applicant has reviewed the use standards for solar energy collection devices in Section 4 -30 -50 (h) of the Code and has the following responses to these standards: (a) The devices will have a matte finish or be of a non - reflective color (b) The collectors will not exceed twelve feet (12') in height. (c) The height of the collectors will be measured as specified in the Code. (d) The collectors have been located within an envelope designated on the site plan. The conformance of the site plan and activity envelopes with the applicable standards of the Land Use Code is addressed in the sections which follow. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 4 000037 II. STANDARDS FOR ACTIVITY ENVELOPE AND SITE PLAN REVIEW Chapter 7 of the Land Use Code establishes the standards related to the quality of development in Pitkin County. Following are the applicant's responses to the applicable standards of that chapter, as specified in the pre - application summary form. A. Site Preparation and Grading (Sec. 7- 20 -10) (a) Grading and Fill Placement. The applicant agrees that all grading and filling associated with this project will take place within the designated activity envelopes. (b) Clearing, Grubbing and Vegetation Removal. The applicant agrees that all clearing, grubbing and vegetation removal associated with this project will take place within the activity envelopes depicted on the site plan. (c) Tree Removal and Mitigation. It is not anticipated that any trees with a caliper size of 6" or greater will be removed as a consequence of the development of the planned improvements. Most of the vegetation that is removed will be oak brush and similar brushy species that must be thinned to mitigate for the wildfire hazard and to allow for the planned structures to be installed. The applicant will submit a landscape plan at the time of building permit review showing the additional trees and other native vegetation that is proposed to be planted within the landscape and building envelopes. (d) Protection of Natural Terrain. The applicant agrees to follow those design and construction techniques that may be recommended by the County Planning Engineer or the Community Development Director to mitigate any physical or visual damage from the proposed development. This shall include, but not be limited to: ♦ Areas disturbed by the re- development of this property will be re- vegetated using native grasses, shrubs and trees. Re- vegetation will be completed during the first planting season after completion of the construction. A detailed grading and landscaping plan will be provided as part of the building permit submission. ♦ Topsoil will be removed and saved prior to any mass grading or excavation, and will be replaced following construction. A minimum of 6" of topsoil will be placed in areas that are to be re- seeded. ♦ Appropriate weed prevention techniques will be employed that are consistent with the provisions of the 2006 Revised Pitkin County Weed Management Plan. ♦ The County's adopted erosion and sedimentation control and stormwater management standards will be followed. Sediment barriers will be placed on -site as necessary to control the impacts of soil disturbing activities (see Section III.C, below). Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 5 000008 B. Steep and Potentially Unstable Slopes (Sec. 7- 20 -20) Section 7 -20 -20 of the Land Use Code provides standards for development on slopes of less than 30 %, 30% to 45 %, and 45% and greater. The overall site plan depicts topography throughout the property, illustrated as two foot (2') contours within the activity envelope and ten foot (10) contours for the remainder of the property. An analysis of the slopes on the property demonstrates that while there are significant, continuous areas of the property with slopes in excess of 30 %, none of those continuous areas are located within the proposed activity envelopes. Therefore, the development planned within the proposed envelopes is in compliance with Section 7 -20 -20 (d) of the Code which allows development on slopes that are less than 30 %. However, the site plan enlargement shows that there are two limited, discontinuous areas within the proposed activity envelope with slopes that exceed 30 %. The applicant concludes that these areas qualify as minor anomalies, as described in Section 7 -20 -20 (c) (3) of the Code. These areas appear to have been created by the prior disturbance and clearing of the site, including the installation of the existing driveway cut. These slopes are a discontinuous, man -made change in an otherwise continuous natural slope and therefore fit within the Code's definition of a slope anomaly. The applicant does not plan any significant development activities on these minor anomalies as they are located either above or below where the cabin, ADU and other improvements are proposed to be located. However, there is likely to be some grading of these areas as part of the improvements to the existing driveway and during construction of the residence. Therefore, prior to issuance of a grading permit for any development that would alter the anomalies, the applicant agrees to have an engineer licensed in the State of Colorado review the slopes in excess of 30% that are to be disturbed. The engineer will be asked to demonstrate that the ground surface of those slopes is not prone to instability and that the proposed re- grading will not cause greater instability or increase the potential for slope failure along those disturbed slopes. This demonstration will authorize disturbance of the minor anomalies pursuant to Section 7 -20 -20 (c) (3) of the Code. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 6 uUUO39 C. Water Courses and Drainage (Sec. 7- 20 -30) (b) Encroachment or Channeling. No encroachment or channeling activities are proposed as part of the development planned for the property. (c) Drainage. The applicant agrees to prepare and submit a drainage report as part of the building permit submission. The report will demonstrate how the planned development will allow for positive drainage away from all structures and how historical drainage flow patterns and runoff amounts will be maintained, as required by adopted County Codes. (d) Groundwater. No activities are proposed that would interfere with groundwater recharge or pollute groundwater. No contaminants will be introduced into the groundwater as a result of the proposed development. (e) Irrigated Areas. The proposal will have no effect on water supplies available for the irrigation of agricultural lands or any existing and decreed water rights. (t) Irrigation Ditches. The applicant is not aware of any irrigation ditches in the vicinity of the parcel that would be impacted by the proposed development. (g) Sedimentation. The applicant will comply with the County's standards for controlling sedimentation. This will be demonstrated via a grading and erosion control plan that is included with the building permit submission. This plan will locate and describe the erosion and sedimentation control measures that will be installed during construction. Sediment barriers, to include straw check dams /straw waddles, silt fences, and similar filtering devices will be placed down -slope of all disturbed areas. Disturbed areas will be re- vegetated no later than one growing season after completion of construction by applying native seed mixes and fertilizer to disturbed areas. All areas that are seeded will have weed -free straw mulch applied to them after seeding is completed. (h) Water Quality. (1) The applicant has located the proposed structures so they are not within 100' of any perennial stream corridor or wetland area. (2) The applicant will comply with those state and federal statutes and regulations concerning water quality that may apply to the proposed development. (i) Efficient Water Use. The applicant will comply with this standard. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 7 UODU10 D. Geologic Hazards (Sec. 7- 20-50) According to the County's geologic hazard maps, there is an alluvial fan that has the potential to generate debris flows and mud hazards that could affect the property. On -site inspection of the property also revealed the potential for rockfall hazards to affect the property. Therefore, the applicant engaged Yeh and Associates to study these hazards and to identify the appropriate areas of the property where the least possible hazard is posed to improvements. The summary report prepared by Sylvia White, Staff Geologist and Richard Johnson, P.E. is attached as Exhibit #4. Based on their analysis and conclusions, the applicant was able to determine that the proposed building envelope (the primary site) is the least hazardous portion of the site from a geologic standpoint. Two other areas of the site which were originally being considered for structures (which the report identifies as the secondary and tertiary building sites) were dropped from consideration for structures because each required some geologic hazard mitigation while the primary site avoids the hazards and therefore did not require any such mitigation to be installed. Following is a summary of the contents of the report. 1. Debris Flow Hazard Yeh and Associates performed field mapping of the existing drainage channel that flows through the northern portion of the property. The resulting drawing is included as Figure 1 of their report. It shows that the channel flows in a generally west to east direction across the top of the property. It exits the property when it crosses under Cherokee Lane via an existing, rather narrow culvert. The report characterizes the debris flows as small events that are generally confined within the existing drainage channel. However, the culvert under Cherokee Lane is not properly sized to pass design level mud flow events. Therefore, during moderate to very large events, the culvert is likely to plug or be overwhelmed. That results in mud flows over- topping the culvert, as evidenced by the material that has been deposited on the property across from the subject property. The report concludes that the portion of the site where the building envelope is proposed to be located is "topographically above the potential breach point of the existing channel and anticipated debris flow path ". Therefore, it characterizes the debris flow hazard to the envelope as "negligible ". However, the area across the road from the main building envelope is below the culvert and could be subject to a hazard risk during a moderate to very large event. The analysis indicates that when flows overtop the culvert, some of the mud will run down Cherokee Lane at depths of 1' to 2'. The applicant had considered this portion of the property as a possible building site at one point but abandoned those plans due to this potential hazard. This area is, however, Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 8 moo t / planned for use as the leach field location. The leach field is proposed to be located toward the northern portion of this part of the site, at the greatest possible distance from where the report indicates that a mud flow could impact this part of the property. Response to Code Standards for an Alluvial Fan Section 7 -20 -50 (d) of the Land Use Code states that development may be permitted within an alluvial fan if the use: (1) Is located and designed in accordance with a site evaluation and recommendations of a qualified professional engineer or geologist licensed in the State of Colorado. Response: As described above, site evaluations and recommendations have been provided by qualified professional engineers and geologists who are licensed in the State of Colorado. The planned development has been located in accord with their recommendations to avoid the areas where the hazard could impact a planned structure. (2) Is protected by channeling, damming or diverting potential mud or debris flows utilizing engineering structures designed by a professional engineer or geologist licensed in the State of Colorado. Response: The proposed structures have been located so they will not be subject to the debris flow hazard. The proposed leach field could be exposed to a mud flow event. Therefore, if the County so requires, the applicant will design and install a diversion structure (a berm) around the proposed leach field to protect it from a mud flow event. Since no structures or human activities would occur at the leach field site, the applicant requests that no such berm be required. (3) Avoids disturbance in the drainage basin above the fan unless an evaluation of the effect on runoff and stability of the fan shows that disturbance is acceptable. Response: The applicant will not engage in any activities that would disturb the drainage basin above the fan. 3. Rockfall Hazard The field work identified two potential rockfall source areas that could affect the proposed building envelope. Figure 2 in the report shows what it identifies as the upper and lower source areas. The report indicates that "there is evidence of frequent rockfall events originating from most of the cliffs ". Therefore, the authors of the report conducted a study of the projected trajectories of rocks from the upper and lower source areas towards portions of the building envelope. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 9 t7uQU u i? The modeling that was completed looked at the primary site (the proposed building envelope) and the secondary site (the flat area below the existing cabin). This analysis indicated that no rocks from the upper or lower sources reached the primary site but some rocks could reach the secondary site. This led the applicant to remove the secondary site from consideration for structures, with it being relegated to a landscape lawn area only. Therefore, the report concludes that "the risk of rockfall at the primary site is negligible and rockfall mitigation is not necessary". Since the hazard has been avoided by the proposed site plan no response to the standards for mitigating rockfall hazards has been provided. However, the applicant agrees to the following standards to ensure that the development does not exacerbate the rockfall potential on the site: The applicant agrees not to engage in any activities or development that would (a) Increase water supply to cliffs or overhangs; (b) Remove protective vegetation; (c) Add weight or otherwise disturb overhanging strata; (d) Make any excavations that remove underlying support; or (e) Increase erosion that removes underlying support. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 10 otuul3 E. Wildfire Hazards (Sec. 7- 20-60) During the pre - application conference with staff, the applicant was informed that the County's wildfire hazard maps designate this site as being in a severe wildfire hazard area. A site visit was conducted with Eric Petterson, one of the County's designated wildfire experts. The purpose of the site visit was to evaluate the wildfire hazard present on the property and to identify the appropriate mitigation strategy for its development. A letter from Mr. Petterson summarizing his conclusions from this site visit and providing his recommendations for wildfire mitigation is included as Exhibit #5. Based on his site visit, Mr. Petterson has confirmed that the proposed building envelope is located in an area that is subject to a severe degree of wildfire hazard due to the combined effect of the slopes on the property (some of which exceed 30 %) with the fuels around the home site (which are continuous and brushy). The mitigation standards for development in wildfire hazard areas are found in Section 7- 20-60 of the Land Use Code. Following are the applicant's responses to these standards. (1) Defensible Space (a) Brush, debris, and non - omamental vegetation shall be removed within a minimum ten (10) foot perimeter around the structure. Response: The applicant will comply with this requirement. (b) Vegetation shall be reduced to break up the vertical and horizontal continuity of the fuels a minimum of a thirty (30) foot perimeter around a structure built on flat ground. (c) Spacing between clumps of brush and vegetation within the thirty (30) foot perimeter shall be a minimum of two (2) times the height of the fuel. Maximum diameter of the clumps shall be two (2) times the height of the fuel. All measurements shall be from the edges of the crowns of the fuel. Response: Mr. Petterson has modified these standards as they would apply to this property. He recommends that clumps of non - coniferous brush and vegetation up to a sixty foot (60') perimeter (or to the lot boundaries if more restrictive) be thinned by removing 60% of the original shrubby canopy and that the maximum diameter of the remaining clumps be limited to one -half (1/2) the height of the fuel. The applicant will comply with these recommendations. (d) All branches from trees and brush within the thirty (30) foot perimeters shall be pruned to a height of 10 feet (10) above the ground, and removal of ladder fuels from around trees and brush. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 11 UUUU14 Response: The applicant will comply with this requirement. (e) Tree crown separation within the thirty (30) foot perimeters shall have a minimum of ten (10) feet between the edges of the crowns, except for mature stands of Aspen trees where ladder fuels have been removed. In areas of Aspen re- generation, understory shrubs and down and dead materials shall be removed. Response: Mr. Petterson recommends that tree crown separation be a minimum of 20' except for Aspen trees, which do not need to have a tree crown separation. The applicant will comply with that recommendation. (fJ All branches that extend over the roof eaves shall be Mmmed and all branches within fifteen (15) feet of the chimneys shall be removed. Response: The applicant will comply with this requirement and will also comply with the requirement that no branches may be located within fifteen feet (15') of any structure. (g) The density of fuels up to a one hundred (100) foot perimeter of the structures shall be reduced where natural reduction has not already occurred. Response: Mr. Petterson has not recommended that this standard apply to this property. (h) All deadfall up to a one hundred (100) foot perimeter shall be removed. Response: The applicant will comply with this requirement. (i) The property owner shall be responsible for the continued maintenance of the defensible space vegetation requirements. Response: The applicant will comply with this requirement. Q) No new conifer trees shall be planted within ten (10) feet of a residence. Response: Mr. Petterson recommends that no coniferous trees be planted within 20' of the residence or anywhere below the residence. He also recommends that installed or native landscaping within twenty feet (20') of the house be limited to grasses and forbs and not contain any brushy species. Aspen trees are allowed near the house, but may not be within ten feet (10') of the structure, and shall be kept limbed to ten feet (10') unless the tree is less than ten feet (10') tall. The applicant will comply with these recommendations. (k) No flammable mulches shall be placed within two (2) feet of a residence. Response: The applicant will comply with this requirement. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 12 uuuul5 2. Access (a) Access roads and driveways shall be built to County standards; however, these standards may be increased to mitigate wildfire hazards based on comments provide by the Colorado State Forest Service, the Sheriffs Department, local fire protection districts, and/or a person approved by the County as an expert in wildfire areas and mitigation. Where feasible, looped routes of access/egress to a public road shall be incorporated in the design of a proposed development. Looped routes of access/egress is defined as two (2) or more dedicated access roads to the main artety/highway for widely separated ingress/egress; looped drives with one entrance point or divided single entrances do not satisfy this condition. Where this is not feasible, the Community Development Department may approve vehicle turnaround areas a maximum of seven hundred -fifty feet (750) apart, installed between the road intersection and its terminus. Turnaround areas shall be the same standard as cul -de -sac tumaround pads; these may be incorporated in the proposed driveway entries. Response: The existing driveway does not appear to comply with the County's road width or its grade standards. Therefore, the applicant met with a representative of the Carbondale and Rural Fire Protection District to determine what improvements the applicant should make to the driveway. The District felt that it would be better to maintain the existing straight alignment of the driveway and to widen it to 12' rather than to introduce some curves into the driveway to reduce its grade. The applicant will comply with these recommendations and will provide an area below the house (the landscape envelope) as a turn - around /staging area for emergency vehicles. (b) New dead -end streets (no cu / -de -sacs) shall not be permitted, except for cul -de- sacs and other turnarounds accepted by the applicable local fire district. Response: No new streets are proposed. (c) Cul -de -sac tumaround pads shall have a minimum of a thirty foot (30) drivable surface inside tuming radius, or a hammerhead or other T -tum area acceptable to the applicable local fire district. Response: The applicant will comply with these design standards for the turn - around area. (d) New driveways and access roadways shall enter the roadway at a ninety (90) degree angle for the first twenty -five feet (25) of the driveway. Response: The gravel driveway that serves this property has been in place for many years and provides good driver visibility. No changes to its intersection with Cherokee Lane are planned since the Fire District has not requested such changes be made. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 13 uuuu16 (e) Fuel breaks, as recommended by a wildfire expert approved by the County, may be incorporated into the design of access roads or driveways. Response: The wildfire expert has not recommended a fuel break for this property. 8. Water Supply for Fire Safety (a) When access to a public or private pressurized water system is not available, or if it is necessary to augment the fire protection water systems, private ponds may be used if approved by the Community Development Department and the Fire District. Response: The applicant does not propose to utilize a private pond for fire protection. (b) Any fire department recommendation for individual structure water supply and storage shall be accessible to fire department vehicles from the exterior of the structure through a Fire Department approved mechanism (such as a fire hydrant). The amount of storage capacity shall be determined by the fire protection district, with a minimum of one thousand (1, 000) gallon storage capacity per structure. Response: The applicant will comply with the water storage recommendations of the Carbondale Fire Marshal. (c) Regardless of size, all structures where humans congregate regularly (including detached garages and horse bams) that are located within areas identified as containing "C - Severe Hazard: Trees" or W - Severe Hazard: Brush" wildfire hazard shall be required to install in -house sprinkler systems which meet the standards of the local fire protection district and the adopted building code. Response: The applicant will comply with these requirements (d) All structures greater than five thousand (5,000) square feet in size shall be required to install in -house sprinkler systems that meet the standards of the local fire protection district and the adopted building code. At building permit submittal, the local fire protection district may require smaller structures to be sprinkled due to hazard considerations, emergency access difficulties and lack of proximity to fire protection services. Response: No structure will exceed 5,000 sq. ft. in size. 4. Roofing Materials and Projections At And Below Roof Line (a) Low Hazard Area; and (b) Medium Hazard Area.

Response: The applicant will comply with all of these requirements Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 18 uuOu''21 F. Wildlife Habitat Areas (Sec. 7- 20 -70) According to the pre - application summary form, this property is located within mapped elk winter range. Therefore, the applicant agrees to comply with the dog restrictions applicable to winter range that are described in Sections 7 -20 -70 (f) (2) of the Land Use Code. This means that any dogs that are kept on this property will be properly kenneled. The applicant will also comply with the timing of construction limitations in winter range that are stated in Sec. 7 -20 -70 (g) (1) if such limits are recommended by the Colorado Division of Wildlife. Section 7 -20 -70 (c) of the Code establishes the County's general land use standards for wildlife habitat areas. Following are the applicant's responses to these standards. 1. When existing native vegetation must be altered within the Activity Envelope, the applicant may be required to prepare a habitat mitigation plan acceptable to the County. Such mitigation plan may substitute (in a nearby area on the subject property) vegetation equal in type and quantity to that being removed to mitigate effects on wildlife species. Should there be no opportunity on the property for habitat mitigation or restoration, off -site mitigation benefiting the same species may be required, or financial mitigation may be paid into a County habitat mitigation fund should such a fund be established in the future. Response: The applicant will submit a landscape plan at the time of site plan review that describes the vegetation that will be planted to compensate for any significant vegetation that is removed as a consequence of the development of the property. 2. Manipulation of vegetation outside of the Activity Envelope is prohibited. Response: The applicant will comply with this requirement. 3. Mesh or woven wire fences are prohibited outside of the Activity Envelope. Response: The applicant will comply with this requirement. 4. Wood rail fencing shall employ three rails or less, be the round or split rail type, shall not exceed 54 inches in height above ground level and 12 inches in width (top view) and shall have at least 18 inches between two of the rails. Response: The applicant will comply with this requirement. 5. Wire fencing must be three strands or less. The top wire shall be twelve point five (12.5) gauge twisted barbless type at a maximum height of forty -two (42) inches. The middle strands (which may be barbed) should be located a minimum twelve Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 19 Uuu!u2Z (12) inches apart and from the top wire preventing entanglement when mule deer jump over. The bottom strand should be sixteen (16) inches from the ground. Response: The applicant will comply with this requirement. 6. Tall, overly mature trees and standing dead trees (snags) should be retained at the rate of two (2) to five (5) per acre whenever possible as nesting or perching habitats. Response: The applicant will comply with this requirement. 7. In areas of high black bear activity, fruit bearing trees and shrubs shall be prohibited within the Activity Envelope. This does not include pre- existing native trees and shrubs. Response: No fruit bearing trees or shrubs will be planted on this property. 8. Development shall be clustered to the maximum extent possible to minimize impacts on wildlife. Response: The development will be clustered into the lower portion of the property. 9. Access shall be provided to the Colorado Division of Wildlife for trapping, tagging, studying, or otherwise managing wildlife. Response: The applicant will comply with this requirement if so requested. 10. Trash /garbage shall be kept in an approved bear resistant container or enclosure. Response: The applicant will comply with this requirement. 11.

All seed feeders shall include a seed catchment pan to catch discarded seeds. 12. Horse grains, pellets, and cookies shall be stored in bear resistant containers or enclosure. 13. Pet food shall not be left outside. Response: The applicant will comply with each of these requirements. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 20 UuuU23 G. River and Stream Corridors and Wetlands (Sec. 7- 20 -80) Section 7 -20 -80 (a) (2) (a) of the Land Use Code establishes the following requirement for new development: "All activity and development after the 5th of July, 2006 shall maintain a riparian area /wetland buffer of at least one hundred (100) feet measured horizontally from the identifiable high water line of each feature identified in subsections (a)(1)(a) and (b) above. This one hundred (100) foot setback may be reduced to between one hundred (100) feet and a minimum of fifty (50) feet upon demonstration by the applicant that such reduction shall not result in water quality degradation, stream bank erosion and /or a reduction in the quality of riparian or wetland habitat pursuant to standards in Section 7- 20-80 (4)." The drainage that passes through this property is a blue line stream on the USGS maps for this area, Therefore, the building envelope for this property has been drawn to comply with the 100' setback, ensuring that no buildings will be constructed within 100' of the existing drainage. The existing driveway does protrude into the 100' setback and will likely need to be improved, at a minimum to provide a turn - around area for emergency vehicles. These improvements, which have yet to be fully designed, would appear to qualify for an exemption from the 100' setback. Section 7 -20 -80 (a) allows for roads and similar facilities within the 100' setback "upon a finding that there is no feasible altemative location and that any adverse impacts will be mitigated, as required by subsection (d) below ". Examination of the site plan makes it apparent that there are no alternative ways to provide access to the cabin site, particularly since the driveway is already improved through this area. Therefore, the applicant makes the following commitments to mitigate any impacts on riparian vegetation from improvements made to the existing driveway: The applicant will submit an erosion control plan with the driveway permit that will ensure the improvements due not increase sediment or suspension loads in the drainageway. Removal or disturbance of vegetation will be minimized to the maximum extent practicable. Any vegetation that is removed will be re- vegetated as quickly as possible. Given the fact that the lands beyond the drainage channel are not truly riparian in character (in fact they are a dry hillside that supports primarily oak brush) the applicant would request that the replacement vegetation be characteristic of the types of native grasses and shrubs that are found on this type of hillside. • The will be no alteration or channelization of the drainage channel itself. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 21 uuuv24 H. Scenic View Protection Areas /Rural Character (Sec. 7 -20 -120) The site visit which the applicant and his representatives conducted with the County staff demonstrated that the subject property is visible from one location along Highway 133. However, the distance from the Highway to the building envelope is quite substantial (several hundred linear feet). Therefore, the property sits well into the visual backdrop and is not in the scenic foreground as viewed from this road. This means that the proposed development will not significantly alter the scenic quality or rural character of this scenic view protection corridor. In fact, as shown in the photo - simulation that has been provided, the proposed house and CDU will inject two more small roof forms into a view in which a considerable number of existing structures can already be seen. So overall, the scenic corridor will not be significantly altered by the proposed development. The applicant has provided several visual images to demonstrate the compliance of the proposed development with the County's scenic view protection standards. Included in this application booklet are the following illustrations: • Architectural elevations showing the proposed structures, with primary building materials identified; and • A photograph of the hillside taken from State Highway 133, onto which a computer has simulated images of the residence and CDU. Following are the applicant's responses to the County's scenic view protection standards. 1. The proposed development shall utilize existing topography and natural vegetation, such as ridges, hills and existing trees, to screen buildings to the maximum extent practicable. Response: Existing topography and natural vegetation help to screen the proposed structures from view from most locations along Highway 133. As we drove along the Highway there was only a single location where we could see the poles that were installed on the property to simulate the maximum height of the structures. The site is otherwise invisible due to the topography and vegetation that is present along the Highway which screens the property from public view. 2. The proposed development shall avoid the location of structures within the Scenic View Protection Areas and shall avoid the location of structures within any Viewplane identified in the State Highway 82 Corridor Master Plan and Down Valley Comprehensive Plan, if possible. If location outside of the Scenic View Protection Area and defined viewplanes is not practicable, then the proposed development shall not be located on the highest ground or most visible portion of the site as viewed from those corridors listed above. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 22 uuOu'25 Response: The proposed structures are not located on the highest ground or the most visible portion of the site. In fact they have been located on the lower portion of the site (at and (below elevation 6,950) on a property that reaches all the way up to elevation 7,400. 3. The proposed development's height and bulk shall be designed to avoid, to the maximum extent practicable, the visibility of buildings from those corridors listed above. This may include, but shall not be limited to, breaking the mass of the building down into a series of smaller forms, articulation of the building facades to avoid a wall or row effect, and staggering rooflines to avoid a long unbroken plane. Response: The applicant proposes two relatively smaller buildings that together contain far less floor area (approximately 4,000 sq. ft.) than is allowed on this site (5,750 sq. ft.) Elevations have been provided showing the proposed residence. These line drawings show that the applicant plans to develop a traditional log cabin, with pitched roof and porch elements and dormers designed to break down the mass of the building down into a series of smaller forms. The cabin will also have railings on the decks, a variety of window types and a stone chimney that tend to break down the visible appearance of the cabin. A visual simulation has also been prepared, showing how the residence and CDU will appear from Highway 133. As noted above, there was only one place along the road where this property could be seen. When these structures are simulated onto the photo it does not dramatically change the visual image but instead just adds two more roof forms where there are already a number of other neighboring residences visible. 4. The proposed structure shall be placed so that it does not project above a ridgeline such that a structure silhouettes against the sky when viewed from those corridors listed above, unless there are no alternate building sites on the lot or parcel. Response: The proposed structures will not penetrate a ridgeline and will not silhouette against the sky as viewed from Highway 133. This conclusion should be quite clear from the photo simulation that has been provided, which demonstrates that no ridgeline penetration could possibly occur from this proposal. 5. The proposed development shall be designed to complement the natural topography of the land through the use of techniques such as earth sheltered design, the use of natural materials and coloring, the use of low - reflectance materials, or clustering of structures on the least visible portions of the site. When a building is proposed near a ridgeline, then its form (particularly its roof form) shall replicate, parallel or compliment the natural form of the ridgeline so that it appears to be an element of the natural ridgeline. Response: The structures will use natural materials or man -made materials that have Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 23 UL`U'j26 natural coloring. The proposed elevations show that the exterior of the residence will be a log cabin with shake shingle siding and a stone veneer base and chimney. The cabin will have a metal roof, with a natural color that is still to be determined. The colors used in the simulation are a graphic representation only and do not represent a commitment to those shades by the applicant. 6. The proposed development shall preserve natural vegetation and avoid development within irrigated meadows to the maximum extent practicable. Response: The applicant is required to thin vegetation on the site to reduce the wildfire hazard but will otherwise preserve the natural vegetation on the site. No development is planned within an irrigated meadow. 7. The proposed development shall install utilities in locations and through procedures that minimize visual impacts to the maximum extent practicable. Response: Utilities will be installed underground within the driveway and in combined trenches whenever practical. Any cuts required to provide utility service will be revegetated within one growing season after the utility installation is completed. 8. All satellite dishes in the proposed development shall be located to minimize visibility from those rights -of -way listed above and shall use earth tone colors and /or screening to minimize their visual impact. Response: The applicant will comply with these requirements. 9. The proposed development shall not utilize earth moving and berms as the primary means of compliance with these regulations, but earth moving may be utilized in conjunction with other techniques to comply with the standards of this section. Where earth moving techniques are necessary, man -made forms should be undulating and natural in appearance. Response: Earth moving and berms are not proposed as the means of complying with these regulations. 10. In the Rural Area only, development shall be located so that activities and development occur in at least one of the locations specified in subsection (e) as they may apply to the particular property. Response: None of the locations specified in sub - section (e) apply to this property. 11. The exterior of all development shall be built or painted with indigenous earth tone materials or colors. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 24 uuuu27 Response: The structures will be built with a combination of man -made and natural materials. The applicant agrees to paint or stain these materials with earth tone colors. 12. All roofs shall have a non - reflective color or composition. Reflective roof materials shall not be used unless the materials are treated prior to installation to eliminate reflection, with the exception of materials associated with solar or photovoltaic equipment. Response: The applicant will comply with this requirement. 13. Lands disturbed by earth moving or berms should be revegetated using native species that are already growing on or near the site. Topsoil shall be stockpiled and placed on disturbed areas. Irrigation shall be provided to the revegetated areas if it is necessary to ensure the survival of planted native species. Response: The applicant will comply with this requirement. 14. To the maximum extent practicable, roads and driveways shall be located to skirt the edge of and avoid dividing meadows and pastures and to avoid major road cuts. Roads and driveways should take advantage of the screening potential of natural topography and existing vegetation. Existing roads and driveways shall be used where practical. To enhance screening, a row of trees may be planted along the roads or driveways. To the maximum extent practicable, roads and driveways located around the edge of or in meadows shall be laid out with soft, curving edges and shall avoid straight line corridors that are incongruous with the natural setting. Response: The applicant proposes to utilize the existing driveway and to improve it in a limited manner, to avoid any major road cuts and to maintain existing vegetation to the extent possible. Some of this vegetation will need to be cleared to address the wildfire hazard potential but additional planting will be installed to screen the driveway. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 25 UuUi,28 I. Landscaping and Vegetation Protection (Sec. 7 -20 -130) A detailed landscaping and grading plan will be submitted with the building permit set. The landscape plan will include plantings of native tree species to screen the proposed structures from view and to supplement the native vegetation that is already present on the property. Disturbed areas will be re- seeded using a County- approved native seed mix. Following are the applicant's responses to each of the standards in this section: (b) General Provisions. 1. Protection of Natural Vegetation. The applicant will preserve the natural vegetation on the site, except for that vegetation within the activity envelope that must be removed to build the proposed improvements or which must be thinned to mitigate the wildfire hazard. 2. Conformance With Wildfire Regulations. The applicant will comply with the recommendations of the wildfire expert to mitigate the wildfire hazard on this site. 3. Berms. A berm is not proposed for this site. 4. Landscape Enclosures. Landscaping is not proposed to be used to enclose the boundary of the parcel. 5. Visibility Clearance. No landscaping is proposed where it would inhibit the visibility of drivers. 6. Utility Easements. It is not anticipated that landscaping will be installed over a utility easement 7. Financial Security. The applicant requests that no financial security be required for the installation of landscaping on this property. 8. Maintenance. The applicant agrees to maintain all installed landscaping in a healthy condition and to replace plants that do not survive. (c) Required Landscaping in Rural Areas 1. None of the purposes for which landscaping is required in the Rural Area apply to this proposal. 2. The applicant will cluster the proposed plantings into natural groupings and will minimize planting in regularly spaced lines or rows. Indigenous plant species will be installed on the property. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 26 UUU029 J. Roads, Driveways and Parking (Sec. 7 -30) Access to the subject property is obtained from an existing driveway that intersects with Cherokee Lane. As explained above, this driveway is currently less than 12' wide and has grades in some sections that exceed 12 %. The applicant discussed potential improvements to the driveway with a representative of the Carbondale and Rural Fire Protection District and also with staff of the Community Development Department. Based on those discussions the applicant proposes to widen the driveway to 12' and to maintain its existing relatively straight alignment. This will mean that grades will exceed 12% in certain sections, but will also minimize the need for grading and reduce the amount of native vegetation that must be removed. The applicant will provide detailed plans for the driveway improvements as part of the building permit submission, including a grading and landscape plan for these improvements. Parking on the site will comply with the adopted County standard of 2 spaces per dwelling unit for both the residence and CDU and will comply with all applicable design standards. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 27 uv�u30 K. Public Services and Utilities (Sec. 7 -50) Following is a summary of the proposed utility plan for this property 1. There is an overhead electric line serving the neighborhood that runs along Cherokee Lane. The applicant will extend this line to the residence and CDU via a buried service line. If telephone service is brought to the site it will be buried in the driveway. 2. The applicant plans to utilize propane gas and to have a propane tank on the property. 3. There is an existing on -site water supply well on the property. It is located just below the proposed residence. 4. The proposed location for the on -site wastewater treatment system is shown on the site plan. The applicant will have test pits dug and percolation tests completed before the on -site system is designed. The system will comply with all applicable Pitkin County health codes. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 28 i�u!:u III. SPECIAL REVIEW FOR CARETAKER DWELLING UNIT Development of a caretaker unit requires special review approval from the County. The standards for special review are listed in Section 2 -30 -30 (h) (2) of the Land Use Code. The applicant's responses to these standards are as follows: (a) The special review use shall be consistent with the applicable County Master Plan. Response: The applicable Master Plan for this property is the Crystal River Master Plan. The applicant has reviewed this document and it does not appear to contain goal or policy statements that directly address the appropriateness of caretaker units in this valley. Goal 2.2 of the Master Plan does alludes to caretaker units by stating that deed restricted (rental and sale) second dwellings on parcels should be encouraged where appropriate and where it furthers the goal of having attainable housing. (b) The special review use shall not conflict with any applicable sections of the Pitkin County Land Use Code, including the County Land Use Policies in Chapter 1. Response: To the best of the applicant's knowledge, the proposed development will not conflict with any of the adopted standards or policies of the County Land Use Code. (c) The proposed development must not materially endanger the public health, safety or welfare. (d) The proposed development must not substantially injure the value of adjoining or abutting property. Response: The development of this CDU will not have any negative impact on public health, safety, or welfare and will not adversely affect the value of any adjoining property. (e) The special review use shall be consistent with the intent of the Zone District in which it is proposed to be located. The stated intent of the underlying RS -30 zone district is to permit low density single family residences and customary accessory uses, while recognizing the constraints that natural hazards, wildlife habitat and limited public services and facilities may place on development in the district. A caretaker unit is a customary accessory use allowed by special review in this zone district. The use is appropriate in this location since the building envelope has been located to avoid natural hazards and critical wildlife habitat areas, and the small caretaker unit will not require that additional services be provided. It should be noted that the floor plans for the proposed house only include two (2) bedrooms, so even with the caretaker unit that is proposed, the total bedroom count for the site (3) will be at or below that of a typical residential property. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 29 UUU032 (f) The special review use shall be compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses, or shall enhance the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development. Response: The proposed caretaker unit will be consistent with the character of the surrounding area, which is entirely residential. There are residences of varying sizes, some of which have accessory structures, located within the surrounding neighborhood. (g) The location, size, design and operating characteristics of the proposed special review use must be in harmony with the surrounding area and minimize adverse effects, including visual impacts, impacts on pedestrian and vehicular circulation, traffic generation, parking, trash, service delivery, airAvater pollution or other impacts on natural resources, noise, vibrations and odor on surrounding properties. Response: The caretaker unit will not create significant impacts on the surrounding properties. The small unit (525 sq. ft.) will be located on a level spot just above the residence. Its visibility from Cherokee Lane and from Highway 133 will be limited. This small caretaker unit will generate minimal traffic and other impacts on surrounding properties and would typically be occupied by the applicant's family or friends. As noted above, the total bedroom count for the site remains average, even with the CDU. (h) There must be adequate public facilities and services to serve the special review use, including but not limited to roads, potable water, sewer, solid waste, parks, police, fire protection, emergency medical services, hospital and medical services, drainage systems, and schools. Response: There are adequate facilities and services available to serve a caretaker unit on this property. Potable water will be supplied to this property from the on -site well, which is permitted by the State for two (2) dwelling units (see Exhibit #6). Sewage disposal will be handled by an on -site wastewater disposal system. The proposed caretaker unit should not place any significant demands on other public facilities and services, including solid waste, parks, police /fire protection, emergency medical services, hospital and medical services, drainage systems, and schools. (i) The proposed special review use must comply with any additional standards or requirements stated for such use in Sec. 4 -30 and /or Sec. 2- 40 -20. Response: A response to the standards of Sec. 4 -30 is provided in Section IV of this application booklet. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 30 uuLIJ33 IV. USE STANDARDS FOR CARETAKER DWELLING UNIT According to Section 4 -30 -50 (e) (1) and (2) of the Land Use Code, a caretaker dwelling unit may be developed in the RS -30 zone district, pursuant to the following use standards: (a) It is attached to a single family home. Response: The unit will be detached from the planned residence. Therefore, according to Section 4 -30 -50 (e) (2) of the Code, special review approval is required for the CDU. A response to the special review standards is provided in Section III of this application. (b) The lot or parcel on which it is located conforms to the minimum lot area requirements for each dwelling in the zone district in which the caretaker dwelling unit is located. Response: The subject property does not conform to the minimum lot area requirements of the RS -30 zone district. Therefore, according to Section 4 -30 -50 (e) (2) of the Code, special review approval is required for the CDU. A response to the special review standards is provided in Section III of this application. (c) The caretaker dwelling unit shall not exceed one thousand (1,000) net livable square feet on lots or parcels that are thirty thousand (30,000) square feet or greater in lot area, and seven hundred (700) net livable square feet on lots or parcels that are less than thirty thousand (30, 000) square feet in lot area. Response: The CDU will contain approximately 525 sq. ft. of net livable area. (d) The floor area of the caretaker unit shall be included in the total allowed floor area for the lot or parcel of land. Response: The CDU has been counted toward the allowable floor area for this property. (e) Two (2) off - street parking spaces shall be provided for each caretaker unit. Response: The applicant will provide two off - street parking spaces for the caretaker unit. (1) The applicant shall, by deed restriction or other permanent commitment running with the land, guarantee that the caretaker dwelling unit: 1. Shall not be required to be rented; 2. Shall not be sold or otherwise conveyed or separated from the original parcel regardless of the ultimate form of ownership of the caretaker unit; Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 31 uuuu34 3. Shall be limited to occupancy by (i) not more than two adults and related children who qualify as (and have been found by the Housing Authority to be) employees of the community under such guidelines as may be from time to time established, or (ii) members of the owners immediate family even though they may not qualify as employees of the community. 4. Shall be rented for terms not less than six (6) months if rented. Response: The applicant will file such a deed restriction following the County's approval of this application. (g) The caretaker dwelling unit restriction may be removed by the property owner upon approval of the Community Development Director, subject to the requirement that the dwelling is removed or modified. If modified, the remaining improvements must no longer be capable of occupancy as a Dwelling Unit and must otherwise meet applicable Code requirements. Response: The applicant agrees to abide by this limitation. Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 32 UUfJiJ35 V. GMQS EXEMPTION FOR CARETAKER DWELLING UNIT Section 6 -30 -40 (c) of the Code authorizes a GMQS exemption for a caretaker dwelling unit pursuant to the following provisions: One (1) Caretaker Dwelling Unit ( "CDU') may be exempted from Growth Management on any lot or parcel located in a zone district in which a CDU is an allowed use, a use allowed by special review, or a use allowed as part of a master plan, as shown in Table 4 -1. Response: A CDU is a use allowed by special review in the RS -30 zone district. The CDU may be allowed even if the lot or parcel is substandard in size and the resulting development on the lot or parcel would not conform to the underlying zone district's minimum parcel size for each dwelling unit, subject to the standards in Sec. 4 -30 -50 (e). Response: The parcel is substandard in size, and the necessary responses have been provided to the standards of Sec. 4 -30 -50 (e) and to the special review standards. The CDU may be either attached to a single - family dwelling unit ('principal dwelling') or other use or may be detached from the principal dwelling or other allowed use if it complies with the standards in Sec. 4 -30 -50 (e). Response: The CDU will be detached from the principal dwelling but complies with the standards of Section 4 -30 -50 (e). Feldman Activity Envelope /Site Plan and Caretaker Dwelling Unit Page 33 OLIUJ36 VI. CONCLUSION The applicant has responded to all applicable criteria of the Pitkin County Land Use Code, pursuant to direction given by staff during the pre - application conference. The applicant has demonstrated that the proposed activity envelope and site plan and the proposed CDU comply with those Code standards. The applicant will respond in a timely manner to requests by any reviewing agency for additional information, or clarification of the statements made herein.

The investigation was performed to evaluate potential debris flow and rockfall hazards at three potential building sites. The site investigation consisted of geologic reconnaissance and rockfall modeling. This report summarizes our field investigation, the results of our analyses, and our conclusions and recommendations based on the locations of the proposed building sites. 1.2 Site Conditions Yeh and Associates personnel visited the site on July 5 and August 25, 2012. The subject parcel is located at 101 Cherokee Lane in Pitkin County, Colorado (Figure 1) within the Crystal River drainage. The site is located at the base of a northeast trending ridge. An existing cabin structure is located on the parcel (Primary Site). A relatively flat portion of the site is located south of the cabin (Secondary Site) and appeared to be used as equipment storage. In addition, a relatively flat area located below Cherokee Lane was void of vegetation (Tertiary Site). The existing grades are nearly level at the three sites and the slopes above the sites were very steep with grades of up to 66 percent. Existing vegetation included trees, scrub oak and other natural brush and grasses. 2.0 INVESTIGATION AND ANALYSES 2.1 Debris Flows Figure 1 presents our field mapping of the drainage channel and potential debris flow paths. Observations suggest that the source area and channel size are adequate to produce a debris flow event. Evidence was observed that several small debris flow events occurred this year and deposited materials around the culvert and on the roadway. Our observations also indicated that small debris flow events are generally confined to the drainage located in the northern portion of the property. Photo 1 shows the existing channel. A berm was observed along the east side of Cherokee Lane. The berm appeared to consist of debris flow remnants that were likely removed from the road after an event occurred. The debris flow materials observed along the road suggest the existing culvert is not sized to pass design level events. During moderate to very large events, the culvert likely plugs or is overwhelmed and the debris flow materials uuuJ4b 1 /A Feldman Property Geohazard Consultation Project No. 212 -145 overtop the road and flow to the south over the road as evident by the location of berm that placed a result of debris flow materials being removed from the road. Photo 1 — Channel on north side of Cherokee Lane 2.2 Rockfall We identified two potential rockfall sources that we believe could impact potential building sites. Figure 2 shows the two source locations labeled as the upper and lower source areas. Photo 2 shows the same sources areas as viewed from the project sites. Due to accessibility, a detailed mapping of the rockfall source area was not performed. The source areas were observed from distance to estimate probable rock trajectories and rock sizes likely to be produced. ,)(1! -) 2 �II UUM47 Feldman Property Geohazard Consultation Project No. 212 -145 Photo 2 — Source areas for rockfall analyses The majority of the slope does not show outcropping bedrock and is moderately to heavily vegetated. While it is possible for rocks embedded in the slope or lying on the surface to dislodge and begin rolling, it is unlikely without significant movement of the ground surface. Our analysis assumed that the most probable locations for initiation of a rockfall event would be from one of the two observed bedrock cliffs above the primary and secondary sites. One primary source area appears to be roughly half way up the slope at elevation 6955 feet and a larger source area is located farther up the slope near elevation 7124 feet (Figure 2). These source areas consist of soft to moderately hard sandstone which has near horizontal bedding planes. The spacing on the bedding planes ranges from about 3 to over 10 feet. Several near vertical, widely spaced joint sets form blocks in conjunction with the bedding planes. From a distance, it appears that the surfaces of many of the discontinuities are open, infilled with soil and highly altered. There is evidence of frequent rockfall events originating from most of the cliffs. Due to the spacing of the bedding and joints in the rock, block sizes are likely to be less than 5 feet in diameter and are typically less than 3 foot in diameter. To estimate the probabilistic trajectories of the rocks, the critical profiles of the site were modeled using the Colorado Rockfall Simulation Program, Version 4.0 (CRSP). CRSP is a 3 000048 /A Feldman Property Geohazard Consultation Project No. 212 -145 widely accepted program for use in evaluating rockfall behavior. A model was developed using USGS topographic maps, Pitkin County GIS data, and terrain data provided by the client. The profiles were chosen to represent the most critical trajectory for the sites. The profile locations are presented on Figure 2. Information provided by the program includes rock bounce height, rock velocity and kinetic energy. Our analyses included rocks of 3 and 5 feet in diameter. The rock sizes were selected based on observations of the source area and rocks observed on the slopes. The density of vegetation as well as the profile and surface properties of the slope makes it unlikely that smaller diameter rocks would impact the site. The starting zone for the rocks was located at the top of the cliffs near elevation 7124 feet for the upper source area, 6955 feet for the lower source area, and allowed for drop heights of up to 10 feet. Slope characteristics were determined in the field and refinement was conducted on these profiles to incorporate our observations and to reflect our experience in local rockfall issues. Analysis points were placed at the potential building site locations on the profile to determine design criteria for mitigation. Based on our observations and experience, we believe the primary site could only be affected by the upper source area and the secondary site could be affected by both the upper and lower source areas. In our opinion, rocks initiating from the lower source area would not impact the primary site. Table 1 shows a summary of the analyses for the primary and secondary sites. Table 1 — Summary of CRSP Analvses Site Source Rock Size Number of Rocks Number of Rocks Area (feet) Simulated Reaching Site 3 100 0 Primary Upper 5 100 0 3 100 0 Secondary Upper 5 100 14 Secondary Lower 3 100 0 000049 4 YA Feldman Property Project No. 212 -145 Geohazard Consultation Our analyses indicated no rocks from the upper source area landed at the primary site and no 3 -foot diameter rocks landed at the primary or secondary site. A summary of the CRSP results for the secondary site for rocks initiating from the upper source area is provided below. Table 2 summarizes the bounce heights, velocities and impact energies for 5 -foot diameter rock size at the analysis points located at the anticipated secondary building site. The complete CRSP output is included in Appendix A. Table 2 — Secondary Site with 5 -foot diameter rocks 3.0 CONCLUSIONS AND RECOMMENDATIONS Based on our reconnaissance and analyses, we are providing our conclusions and recommendations relating to debris flow and rockfall hazards. Other hazards such as slope instability, hydrocompactive soils, seismicity, etc. were not included in this report. 3.1 Debris Flows The primary and secondary sites are topographically above the potential breach point of the existing channel and anticipated debris flow path. The channel confines the debris flows above the culvert area at which point the flows could leave or breach the channel. We believe the debris flow hazard at these sites is negligible. However, the tertiary site is located topographically below the culvert where the drainage crosses Cherokee Lane. A moderate to very large event that overtops the culvert would likelyflow to the south along Cherokee Lane and deposit near or within the tertiary site. Based on the size and amount of debris flow material observed, we anticipate flow depths at the tertiary site of 1 to 2 feet. If development of the tertiary site is planned, we recommend debris flow mitigation be incorporated into site design. Debris flow mitigation could consist of channel improvements such as a larger culvert to pass flows. Debris flows would then be confined to the existing drainage and pass by the site. ,A Uil v V5O Rock Rock Bounce Height Velocity Energy Source Area Size Weight (feet) (ft/sec) (ft -lbs) (feet) (pounds) Average 0.00 Average 11.86 Average 16,673 Upper 5 4,860 Maximum 0.03 Maximum 15.56 Maximum 27,247 3.0 CONCLUSIONS AND RECOMMENDATIONS Based on our reconnaissance and analyses, we are providing our conclusions and recommendations relating to debris flow and rockfall hazards.

As an alternative, depending on building configuration and site development, diversion walls could be constructed to divert debris flows away or around improvements. We recommend diversion walls, channels or structures are able to pass a flow depth of at least 4 feet. More detailed recommendations could be provided after a building site and building configuration is selected. To determine design flows, a storm water runoff analysis should be performed on the drainage basin by a civil engineer. To account for debris flows associated with storm water runoff, we recommend using a bulking factor of 1.5 to 2.0 applied to the peak storm runoff volume. 3.2 Rockfall Our analyses indicated that rockfall mitigation should be considered at the secondary site and that the risk of rockfall at the primary site is negligible and rockfall mitigation is not necessary. For the tertiary site, considering the number of rocks reaching the primary and secondary sites and the existing road above the tertiary site, we believe the rockfall hazard for the tertiary site is also negligible and mitigation in not necessary. Rockfall mitigation is generally divided into two categories, upslope stabilization and down slope protection. Upslope stabilization occurs at the source area and includes the following methods: scaling and trimming, rock bolts, cable lashing, anchored mesh and nets, shotcrete, and buttresses. Because of the size of and distance to the source areas, these are not recommended methods of mitigation for this site. Down slope protection methods may be an appropriate means of mitigation. These include ditches or berms, catch fences and walls, and /or reinforcement of the proposed structures. These methods vary in their effectiveness based on their ability to stop rocks with differing levels of impact energy. Rockfall barriers are generally rated for their ability to withstand an impact load given in units of foot -tons, foot - pounds or kilojoules. Approximate energy ratings for common barrier types are as follows: Berms 400,000 - 10,000,000 ft-Ibs Walls (flexible) 800,000— 3,000,000 ft-Ibs Rockfall fences 60,000 — 2,200,000 ft-Ibs UvL'J51 6 P1 Feldman Property Project No. 212 -145 Geohazard Consultation Reinforced concrete 20,000 ft -Ibs Wood Frame Wall (6 ") 10,000 ft -Ibs The secondary building site is exposed to relatively low energy potential rockfall events. Rock energies at locations where mitigation would be effective are within the range of most fences manufactured specifically for rockfall protection. A berm, wall or fence barrier on the uphill side of the building site would also be an effective mitigation option. Mechanically stabilized earth (MSE) walls could also be used as mitigation. MSE walls are relatively fast to erect and can easily be incorporated into the landscape design. Any mitigation system selected would require maintenance after an impact. Fences require the use of a proprietary system. Mechanically Stabilized Earth (MSE) walls and reinforced berms have a distinct advantage because of their superior ability to withstand significant impacts as well as having a typically lower cost of installation. A combination of ditch and an MSE wall along the western edge of the site would provide a high level of protection for most rockfall events. The wall should have a near vertical face on the uphill side and could have a 2H:1 V slope on the downhill side or a partial or full vertical face depending on how much horizontal space is available. For planning purposes, the wall should be assumed to be at least 5 feet high and should be designed to resist impact energies of at least 20,000 foot - pounds. MSE walls can also be faced with a number of products to improve their appearance. MSE walls can also be used in conjunction with earthen berms to improve their efficiency and therefore minimize cost by reducing the amount of import of materials. VA u 61J52 Feldman Property Geohazard Consultation 4.0 SUMMARY Project No. 212 -145 Based on observations, experience and the results of the CRSP analyses, we estimated the risk for debris flow and rockfall hazards at each site. Table 3 shows the anticipated risk of naturally occurring debris flow and rockfall events. Table 3 — Summary of Risk 5.0 LIMITATIONS The conclusions and recommendations submitted in this report are based upon the data obtained from field reconnaissance and anticipated construction. If the existing slopes are altered by grading operations, wild fire and /or slope instability, we should be contacted to review our recommendations in lieu of the altered slopes. If rockfall or debris flow mitigation is included in the site - specific development plan, Yeh and Associates, Inc. should review the proposed design and construction procedure. The conclusions and recommendations submitted in this report are based upon data obtained from the observations made in the field and numerical modeling. It should be noted that debris flow and rockfall events are sporadic and unpredictable. Rock fragments with energies greater than those evaluated, as well as events with multiple rocks, are possible at this location. The impact energy of very large rocks may exceed the design capacity of most systems. Complete protection from all rockfall hazards is not achievable. Rockfall from a very large event is less likely to occur, but may take place during the design life of the structure. The findings and recommendations given in this report are site - specific, and are only valid for the subject site.

I visited the Feldman Property in Pitkin County, on September 27, 2012 with the owner's representative Mr. Rich Camp. Mr. Camp is preparing a Activity Envelope / Site Plan Review for establishment of an activity envelope. The entirety of the lot is considered "Severe Hazard ". The topography around the homesite can be characterized as a variable slope generally ranging from 5 to 30% with some areas exceeding 45% with continuous brushy fuels. There are no areas within the Lot that are not Severe Hazard areas. Therefore, the following Mitigations are recommended for new construction activities: I. Defensible Space As during construction most of the vegetation within at least 20' of the structure will likely be removed, re- planting of vegetation must adhere to the following: 2. 000055 Brush, debris and non - ornamental vegetation shall be removed and not replaced within a ten - foot perimeter around all structures. Grasses, forbs and irrigated ornamentals are allowed, as long as they are not brushy or coniferous (see below). Clumps of brush up to a sixty -foot (60� perimeter (or to lot boundaries) shall be thinned to 601/6 of the original canopy, leaving approximately 40% of original brush canopy cover. Maximum diameter of the remaining clumps shall be '/i the height of the fuel. All measurements shall be from the edges of the crowns of the fuel. Shrubs shall be cut at the surface, and cut material must be removed. Grubbing out of stumps is not necessary. Re- sprouting will occur, but fuel moistures will be high, and would reduce fire hazards. No remaining clumps should be larger than approximately 25' in diameter. Thinning can be done in an aesthetically pleasing manner, and heavier thinning should PO BOX 833 • GLENWOOD SPRINGS • COLORADO • 81602 PHONE /FAX: (970) 945 -9558 • CELL: (970) 309 -4454 EMAIL: EPETTERSON@RMES- INC /COM • WWW.RMES- INC.COM occur nearer to the house and below the house. Re- sprouting shrubs will likely need to be re- thinned within 10 years. 3. No conifers may be within 20' of the residence, and no conifers may be placed below (down slope) of the residence Tree crown separation shall be a minimum of 20', except for aspen trees, which do not need to have a tree crown separation. 4. No branches shall be within 15' of a chimney, and no branches shall be within 15' of the structure. 5. All deadfall and dead branches on shrubs shall be removed up to a 100' perimeter, or to property boundaries. 6. No flammable mulches shall be placed within T of a residence. 7. Installed or native landscaping within 20' of the house should not contain any brushy species - only grasses or forbs are allowed. Aspen trees are allowed near the house, as long as they are not within 10' of the structure, and are kept limbed to 10' (unless the trees are less than 10' tall). No trees of any species may be within 15' of any window. 8. The property owner shall be responsible for the continued maintenance of the above listed vegetation requirements. II. Access 1. No conifers are allowed within 15' of the driveway. Remove all deadfall within 25' on the downhill side of the road. Remove 50% of the canopy of shrubs within 15' of either side of the access road. This can be done in an aesthetically pleasing manner, but all understory shrubs which are ladder fuels (e.g., snowberry) must be cut to the ground surface. 2. Low vegetation (grasses, forbs and low shrubs) shall be kept mowed to less than 6" within at least 10' of either side of the driveway during the summer season. III. Water Supply for Fire Safety 1. Any fire department recommendation for individual structure water supply and storage shall be accessible to fire department vehicles from the exterior of the structure through a fire department approved mechanism (such as a fire hydrant). The amount of storage capacity shall be determined by the fire protection district with a minimum of 1,000 gallon storage capacity per structure. 2. All structures where humans congregate regularly shall be required to install in -house sprinkler systems that meet the standards of the local fire protection district and the IBC, if desired by the Fire Marshall. At building permit submittal, the local fire protection district may require smaller structures to be sprinkled due to hazard considerations, emergency access difficulties and lack of proximity to fire protection services.

I visited the Feldman Property in Pitkin County, on September 27, 2012 with the owner's representative Mr. Rich Camp. Mr. Camp is preparing a Activity Envelope / Site Plan Review for establishment of an activity envelope. The entirety of the lot is considered "Severe Hazard". The topography around the homesite can be characterized as a variable slope generally ranging from 5 to 30% with some areas exceeding 45% with continuous brushy fuels. There are no areas within the Lot that are not Severe Hazard areas. Therefore, the following Mitigations are recommended for new construction activities: I. Defensible Space As during construction most of the vegetation within at least 20' of the structure will likely be removed, re- planting of vegetation must adhere to the following: 1. Brush, debris and non - ornamental vegetation shall be removed and not replaced within a ten - foot perimeter around all structures. Grasses, forbs and irrigated ornamentals are allowed, as long as they are not brushy or coniferous (see below). 2. Clumps of brush up to a sixty -foot (60� perimeter (or to lot boundaries) shall be thinned to 60% of the original canopy, leaving approximately 40% of original brush canopy cover. Maximum diameter of the retraining clumps shall be 1/2 the height of the fuel. All measurements shall be from the edges of the crowns of the fuel. Shrubs shall be cut at the surface, and cut material must be removed. Grubbing out of stumps is not necessary. Re- sprouting will occur, but fuel moistures will be high, and would reduce fire hazards. No remaining clumps should be larger than approximately 25' in diameter. Thinning can be done in an aesthetically pleasing manner, and heavier thinning should 000060 PO BOX 833 • GLENWOOD SPRINGS • COLORADO • 81602 PHONE /FAX: (970) 945 -9558 • CELL: (970) 309 -4454 EMAIL: EPETTERSONQRMES- INC /COM • WWW.RMES- INC.COM occur nearer to the house and below the house. Re- sprouting shrubs will likely need to be re- thinned within 10 years. 3. No conifers may be within 20' of the residence, and no conifers may be placed below (down slope) of the residence Tree crown separation shall be a minimum of 20', except for aspen trees, which do not need to have a tree crown separation. 4. No branches shall be within 15' of a chimney, and no branches shall be within 15' of the structure. 5. All deadfall and dead branches on shrubs shall be removed up to a 100' perimeter, or to property boundaries. 6. No flammable mulches shall be placed within 2' of a residence. 7. Installed or native landscaping within 20' of the house should not contain any brushy species - only grasses or £orbs are allowed. Aspen trees are allowed near the house, as long as they are not within 10' of the structure, and are kept limbed to 10' (unless the trees are less than 10' tall). No trees of any species may be within 15' of any window. 8. The property owner shall be responsible for the continued maintenance of the above listed vegetation requirements. II. Access 1. No conifers are allowed within 15' of the driveway. Remove all deadfall within 25' on the downhill side of the road. Remove 50% of the canopy of shrubs within 15' of either side of the access road. This can be done in an aesthetically Pleasing manner, but all understory shrubs which are ladder fuels (e.g., snowberry) must be cut to the ground surface. 2. Low vegetation (grasses, (orbs and low shrubs) shall be kept mowed to less than 6" within at least 10' of either side of the driveway during the summer season. III. Water Supply for Fire Safety 1. Any fire department recommendation for individual structure water supply and storage shall be accessible to fire department vehicles from the exterior of the structure through a fire department approved mechanism (such as a fire hydrant). The amount of storage capacity shall be determined by the fire protection district with a minimum of 1,000 gallon storage capacity per structure. 2. All structures where humans congregate regularly shall be required to install in -house sprinkler systems that meet the standards of the local fire protection district and the IBC, if desired by the Fire Marshall. At building permit submittal, the local fire protection district may require smaller structures to be sprinkled due to hazard considerations, emergency access difficulties and lack of proximity to fire protection services.

The proposed new home is close enough to Cherokee Lane to allow access for fire apparatus from the road without needing to use the driveway. I looked at the driveway and there doesn't appear to any better alternative to the proposed location. The steepest part of the driveway is relatively straight and it flattens out before the hairpin turn which is preferable. Overall, I comfortable with the proposed access. The Crystal River Estates subdivision has a 37,000 gallon water storage tank directly off of Cherokee Lane on the west side. It is located adjacent to the Feldman lot at the northeast lot corner. The tank has a direct connection for fire apparatus. The water supply is adequate and no fire sprinkler system is required since the proposed residence is less than 5,000 square feet.

This provides my findings and recommendations. Objectives and Limitations The purpose of my site visit was to: 1. Evaluate the exposure of the proposed main house and ADU to snow avalanches thereby updating my February 14, 2013 report; 2. Observe previous avalanche damage, if any; 3. Utilize detailed topographic maps provided during our site visit; and 4. Calculate avalanche impact and depositional loads on the proposed house and ADU. This report is also subject to the following limitations: 1. Performance standards (loads and surface areas) are provided; structural design details to satisfy the loads are beyond the scope of my work; 2. Any significant changes to the vegetation (e.g. by wildfire or removal of vegetation) may increase avalanche frequency (see final section). Avalanche Terrain and building exposure The site visit enabled location of the main house and ADU with respect to potential avalanche terrain with greater accuracy than was possible during my office -based study in February. Consequently, I now conclude that the main house is not exposed to avalanche path "A" mapped in my February 14 study or path "B ". Path "A" was previously mapped on the USGS map (within the limitations of the 40 -foot contour intervals available) but it flows to the south of the house and ADU and will not reach either Cherokee Lane or the Feldman access driveway. The lower portion of paths "A" and "B" are shown on Figure 1. 145- A second smaller avalanche path "B" with a total vertical displacement of only approximately 150 feet is located above the ADU as also shown on Figure 1. It will produce modest static depositional loads on the ADU as detailed in the next section of this report during design- magnitude 100 -year return period conditions. Path B, because of its small volume, short vertical height and frictional resistance from the existing scrub oak will stop in a gully southwest of the proposed main house. Neither avalanche path "A" nor "B" will reach the main house. Figure 1. Revised avalanche paths and RedBlue zones. Path "A" is the larger. Avalanche loads on the ADU Avalanche loads on the back roof and roof extension of the ADU are shown on Figure 2. Loads result from deposited snow, compressed by the avalanche acts vertically on the roof and extension. It should be treated as static loads. These loads will persist until snow melt in the spring period (probably April at this location) unless is removed. The vertically- acting roof loads in Figure 2 must be added to the design snow loads usually considered in this part of Pitkin County. 2 East Elevation b W -V4- Figure 2. Static avalanche deposit loads on ADU (Elevation view from RCLA drawing). Loads decrease linearly from 150 to zero psf but must be added to snow live loads usually considered at this location. Alternative design for avalanche loads An alternative design would consist of reinforcing the north wall for snow - avalanche impact loads of 100 Ibs /ftz up to the back eaves. Although this alternative is feasible it may not be practical. The impact loads increase from zero to the maximum of 100 Ibs /ftz in approximately 1.0 seconds and may need to be increased by an impact factor' as determined by the structural engineer. Windows would also require design for impact. Room layout in the ADU If the avalanche mitigation suggested is incorporated into the ADU, the layout of rooms is arbitrary. All rooms should be equally safe because structural failure of the building is not anticipated if an avalanche occurs. The entrance should remain as planned. ' The impact factor may be determined empirically by the structural engineer and is related to the rise time of impact (1.0 seconds) and the free period of the building (unknown). It lies between 1.0 and 2.0. 3 Vegetation changes and change in avalanche hazard The avalanche starting zones in both paths (Figure 1) support a Gambel Oak (Quercus gambeiii) shrub forest. This vegetation is not sufficiently dense to prevent avalanches during the rare years when the snowpack is relatively deep or enhanced by wind - transported snow in the starting zones. However, avalanches may become more frequent if the Oak is partially or completely destroyed by fire. We cannot estimate the probability of wildfire. Avalanche frequency Considering current conditions, avalanches at this location will have a small probability (a long return period) due the relatively low elevation (7,000 to 7,500 feet) and the modest snow accumulations expected here. Avalanches capable of reaching into the blue zones (Figure 1) will only be possible when a relatively deep snowpack accumulates, probably during a sustained storm or a period of closely- spaced large storms and the forest is compressed and partly buried by snow in the upper portion of the paths. We estimate avalanches reaching the ADU and terrain south of the main house will have a return period of approximately 100 - years. This is the return period of the design avalanche in Pitkin County.

Due to current potential avalanche risk, my study was office based. A site inspection of the potential avalanche terrain could not be safely completed in late January, 2013. My conclusions are therefore based on a) topographic map evaluation, 2) inspection of good - quality aerial imagery dated 2011, 3) application of avalanche - dynamics modeling, and 4) my experience on more than 180 projects in Pitkin County and more than 1,000 projects worldwide during the past 40 years. Although a field inspection was not completed, I feel the conclusions below are reasonable and probably would not be changed significantly if a site inspection were completed. 1. Objectives This report has the following objectives: a. Evaluation of the terrain and avalanche- dynamics, including design - magnitude' avalanche runout distance, velocity, flow height and impact pressure potential at the building site. b. Discussion of the feasibility of mitigation at the proposed site. ' The design magnitude avalanche in Pitkin County has a return period of 100 years (a 1% annual probability). Ivy 2. Limitations You as my client should know that while our company can and does attempt to uphold high professional standards, the state of scientific and engineering knowledge is incomplete, and does not always permit certainty. The complex phenomena involved in avalanches cannot be perfectly evaluated and predicted, and methods used to predict avalanche behavior change as new research becomes available. While we can and will offer our best professional judgment, we cannot and do not offer any warranty or guarantee of results. Furthermore this study applies to the building site location shown on RCLA drawings dated October 19, 2012 and revised November 19, 2012. Any significant changes to building shape, orientation or location may invalidate the results of this study. 3. Previous Work The building site is located below a steep, short drainage basin that may produce debris flows and rockfall. These potential hazards have been addressed in a report by Yeh and As sociates2 dated August 31, 2012 and revised on November 1, 2012. Evaluation of rockfall and debris flow hazards is beyond the scope of my work. The steep slopes above the building site have also been designated as potential avalanche hazard areas on Pitkin County maps that were done in the mid -1970s by Colorado State University. These maps are generalized, do not consider terrain details and are intended to alert those considering land -use changes that avalanche hazards may exist. The more detailed evaluation of avalanche hazards required by Pitkin County is the objective of the current study, as noted in Section 1 (above). 4. Avalanche terrain A short, steep drainage basin is located directly west of the site. This basin faces to the east and has a maximum elevation of approximately 7,465 feet, roughly 500 -550 feet above the site. The slopes support scattered trees but is covered mostly by low vegetation that could be mostly obscured or compressed during a heavy snowpack year. Deep snowcovers will, however, be unusual at this low - elevation (for Colorado), east facing site. However during unusual and prolonged storms that may be accompanied by persistent winds blowing down the Crystal River canyon, a relatively deep, potentially unstable snowpack may accumulate on steep north- facing parts of the small drainage. Unstable snowpack conditions may produce shallow slab avalanches, particularly on steep, shaded north exposures. We assumed, therefore, that shallow slab avalanches may occur on 2 Geohazard Evaluation Feldman Property 101 Cherokee Lane Pitkin County, Colorado, 9pages, maps, and appendix. 2 some steep slopes during unusual snowpack conditions. Because the slopes remain steep (250 - 40 °) nearly all the way down to the building sites, we feel avalanches may reach and pass the site during unusual conditions 3. Figure 1. Feldman site and avalanche red and blue zones are shown on the USGS topographic map just above center of image. 5. Design - avalanche dynamics and modeling The design- magnitude avalanche that must be considered in Pitkin County has not been observed because it is a low- probability event requiring unusual snowpack and storm conditions,. As noted previously, field observations have not been done thus no field evidence of previous avalanches was obtained. However, we do feel sufficient evidence exists to suggest avalanches are s The Pitkin County land -use code stipulates that rare avalanches (annual probability of 1% or return period of 100 years) must be considered in avalanche mapping, land -use planning and mitigation. 3 possible at this site for the reasons discussed in Section 4. The design avalanche was simulated through application of the Swiss avalanche- dynamics model AVAL -1 D. Avalanche flow height, pressure, and velocity at the proposed building sites were determined. Through avalanche simulations, terrain analysis and aerial -photo interpretation, we determined the sites lie within a blue (moderate- hazard) zone as defined in the County hazard regulations. The avalanche hazard red and blue zones are approximated on the USGS map (Figure 1). 6. Mitigation concepts applicable at building sites Two forms of avalanche mitigation are feasible at the building sites: a. Direct Protection (reinforcement) of main house -- Building surfaces exposed to avalanche impact could be reinforced for avalanche impact loads. Loads would be maximum when surfaces are oriented normal (at right angles) to avalanche flow direction. In this case all of the avalanche momentum would be dissipated by the surface. Loads would be reduced as the impact angle is reduced. Design loads would be dependent on building shape and orientation and are not specified in this report. The maximum load would be less than 200 psf and would act over the lower 10 ft or less of the building. These values are provided for feasibility only; the final design loads will be different and must be determined based on a site - specific analysis. It should be noted that loads > 100psf are well in excess of the usual horizontal loading capacity of a building (which are in the range of 20- 30psf). b. Construction of deflecting barrier — A deflecting barrier could be built on the south and west sides of the main house. The deflecting structure or berm would enlarge an existing natural gully. Such barriers are most effective when built at a small angle to the flow because this reduces forces and barriers are less likely to be overtopped by snow. The RCLA site plan indicates a natural gully in this area on the grading plan. That barrier might be increased in size slightly to also deflect avalanches. A site visit would be needed to provide design details for an avalanche barrier. c. Ramp roof concept to protect "ADU" unit — The proposed ADU unit is currently planned to be located approximately 100 feet to the northwest of the main house (Appendix A). This structure is also well within the blue zone as shown in Appendix B. The most feasible mitigation approach will be to build a ramp roof on the upper side of this building. This will reduce impact loads 4 A blue zone in Pitkin County has a return period between 30 and 100 years and produces an impact pressure normal to the avalanche direction of less than 630 psf (30 kPa). Building may be permitted in a blue zone if mitigation satisfies Pitkin County requirements. The more restrictive red zone does not reach the site (see Figure 1). 4 substantially and could also be designed to resist any static loads from the rare design - avalanche event. The mitigation concepts discussed here are both considered feasible at this site. Performance specifications could be provided after a snow -free site visit of the avalanche path. Modifications to these concepts may result from (1) observations made during the upcoming site visit this spring, and (2) any changes to the design. Report prepared by, Arthur I. Mears, P.E.

(Senate Bill 35, 1972). Some Colorado municipalities require geological studies for sub- division of incorporated land. In addition, local governments are empowered to regu- late development activities in hazardous or mineral- resource areas under C.R.S. 24 -65.1- 101 et seq. (House Bill 1041, 1974) and C.R.S. 34 -1 -301 et seq. (House Bill 1529,1973), respectively. Local- government agencies submit proposed subdivision applications and supporting technical reports to the Colorado Geological Survey "...for evaluation of those geologic factors which would have significant impact on the proposed use of the land," in accor- dance with State statutes. The CGS reviews the submitted documents and serves as a technical advisor to local - government planning agencies during the planning process. Since 1984, the CGS has been required by law to recover the full direct cost of perform- ing such reviews. The adequate knowledge of a site's geology is essential for any development project. It is needed at the start of the project in order to plan, design, and construct a safe devel- opment. Proper planning for geological conditions can help developers and future owners/ users reduce unnecessary maintenance and /or repair costs.

The applicant should address this as part of the Drainage and Erosion Control Plan • All historic and natural drainage patterns shall be improved so as not to affect the neighboring properties or road with flooding • Minimal disturbance shall take place • Natural vegetation shall be preserved as much as practicable • Mitigation measures and BMPs shall remain in place until replacement vegetation is viable • A landscaping plan shall be submitted to both address necessary screening for the site and adequate vegetation replacement — screening requirements shall be re- evaluated at the close of this project and landscaping enhancement may be necessary to address scenic issues • Erosion control matting shall be used for revegetation on steep slopes The applicant shall submit a Large Scale detailed Construction Management Plan (CMP) with each development permit that addresses all phases of construction. This shall include a site plan and written methodology addressing the requirements of a large scale CMP. Top soil shall be kept alive and stored on site using adequate BMPs. The application shall include: • Fugitive dust control • A revegetation plan inclusive of the entire site — native grasses and any wetland species which are natural to this site and shall be used for revegetation • A tire washing device or a vehicle track pad should be used at the egress from the site to ensure that no sediment is tracked off site • Silt fencing, straw wattles and hay bales must be used during construction to control drainage from this site until disturbed areas are adequately revegetated. Y A tree mitigation plan shall be submitted for the removal of any trees larger than six (6) inch DBH — )o Outdoor lighting shall be minimal, shall comply with Pitkin County Land Use Code Noxious weeds should be managed before, during, and after construction r Retaining walls, if over 4 feet in height shall be engineered — no retaining walls more than 4 feet in height are allowed in any setback r' Water rights for the irrigation of landscaping must be demonstrated submittal of the first development permit Y All Pitkin County solar requirements must be complied with • If solar is used as an offset for REMP fees — a solar permit must be submitted before the REMP fees can be offset Note: Access: In the application the applicant proposes to leave the existing driveway at 12' in width — this is not adequate and does not meet the standards of the County's Asset Management Plan (AMP). The driveway also contains grades of more than 12% - Bill Gavette from Carbondale Fire states that he would prefer a Z_ wider drive and the grades of 12% are acceptable — Pitkin County maintains that in order to mitigate for this steep drive that the driveway width must be increased to 16' as stated in the AMP. i% Access: When the Access is reconfigured to meet the requirements of the AMP the culvert at Cherokee Lane must be replaced and up -sized to meet the requirements of the County's AMP — this will increase the size of the culvert to 18" and will help to mitigate the debris flows as discussed in the Yeh and Associates Geohazard Report. The current culvert cannot handle the debris flow from even a moderate event — the report states that the current culvert clogs and the sediment from an event flows onto the road. Y The applicant must meet all the requirements as recommended in the Geohazard Evaluation written by Yeh and Associates and dated 8/31/2012. This report addresses the alluvial fan, rock fall and debris flow r Landscaping: The applicant states that they are going to conduct wildfire mitigation on this property and then they are going to plant "wet" vegetation — they must submit proof of an adequate water supply for additional landscaping on this property AND they must ensure that the new vegetation complies with county wildfire requirements. Additionally a wildfire expert must inspect the property for wildfire compliance prior to C of O.

I understand the applicant seeks approval for a new residence, a caretaker dwelling unit, and associated accessory uses on a 10.73 -acre parcel located at 101 Cherokee Lane, Carbondale. With this referral, I received a copy of the "Feldman Property - Application for Designation of Activity Envelope and Site Plan Review" (Alan Richman Planning Services, November 2012), including a Geohazard Evaluation (Yeh and Associates, November 1, 2012), and an Avalanche Hazard Analysis (Arthur I. Mears, February 14, 2013). Potential geologic hazards. The site is located on an alluvial fan at the base of a steep, east- facing slope on the west side of the Crystal River. Potential geologic hazards include debris flows, rockfall, and snow avalanches. Yeh satisfactorily addresses the debris flow and rockfall hazards. Based on their observations and analysis, I agree that the proposed primary building site does not require debris flow or rockfall hazard mitigation. The proposed building site is located approximately 500 feet outside of a mapped historic avalanche zone, but within an area mapped as having "avalanche potential." Mr. Mears' Avalanche Hazard Analysis contains a good description of the terrain above the site, classifies the site as being "within a blue (moderate - hazard) zone as defined in the County hazard regulations," and makes appropriate conceptual or preliminary avalanche hazard mitigation recommendations. Either of Mr. Mears' proposed mitigation strategies for the main house (structural reinforcement or a deflection barrier) appear to be acceptable. The proposed ramp roof on the upper side of the ADU is a good recommendation also. I agree that a site visit by Mr. Mears, when the snow is gone, is necessary to allow direct observation of the avalanche path, resulting in more specific design recommendations and performance specifications, and /or modifications to the proposed mitigation. Based on the proposed building configuration and floor plans, it appears that the sleeping areas in the main house are located on the downslope side of the home. This should help protect residents from upslope risks, including rockfall and snow avalanches. However, the bedroom of the proposed accessory or caretaker's dwelling unit appears to be located on the upslope side of the structure. CGS recommends that the floor plan be modified so that the sleeping area is located on the downslope (southeastern) side of the accessory structure.
