Inc. 417 Meadow Ct. Basalt, CO 81621 RE: Application Submittal Parcel Number: 239329100159 Owner: Mushroom Rock Partnership LLC Contact, Owners Representative: Joe Turner As the representative for Monica Edelman (agent for Mushroom Rock Partnership LLC), we are applying to have the current Building Permit amended to designate that the home under construction be designated as the PRIMARY DWELLING, and the original dwelling on the property be designated as the SECONDARY DWELLING UNIT. In other words flip flopping the Designations. The original unit which was completed in 2014 is currently designated as the Primary Dwelling and is 1,706 sq. ft. which would qualify as the Secondary Dwelling unit under the Land Use and Development Code. The unit currently being constructed, currently has the designation as the Secondary Dwelling uniUADU. It would be better to designate it as the primary dwelling unit because it would not have a size limitation. The dwelling is currently 3,347 sq. ft., which does not include the addition of the heated breezeway of 384 sq. ft. and garage which is 693 sq, ft. which is exempt from floor area calculations. Both homes are currently fully served by infrastructure, including water, sewer, power, and access. Therefore, we are requesting that the current designation of the two dwellings be flip flopped to meet the Code requirements.

The unit has been constructed and the Applicant is now looking to remodel and expand the unit. The building permit application and research by the Building Department has confirmed that the existing structure has exceeded the size limitation, and the proposed remodel would further expand the size inconsistent with the approved Land Use Change Permit. The unit is fully served by infrastructure including water, sewer, power, and access. Conditions of approval also included mitigation for natural hazards including potential for rock fall and debris flow off the adjacent steep hillside/slopes. The original dwelling on the property is only 1,700 sq.ft. in size and the Applicant is requesting that that the approvals be amended to shift the Accessory Dwelling Unit classification to the original dwelling and allow the current Accessory Dwelling unit to be labelled as the primary dwelling unit. The primary dwelling unit does not have a size limitation which would allow for the proposed remodel. Sat_ 0 The proposal would constitute a substantial modification to an application and require a new submittal. However, since the original approvals the code provisions and definitions of Accessory Dwelling Unit have been updated and the Applicant's proposal would now be reviewed as a "Secondary Dwelling Unit" in accordance with Section 7-701(B). County Staff has identified this Secondary Dwelling Unit/Amendment option for the Applicant as outlined in this Pre -Application summary and included a summary of submittal requirements. The new Application will need to document that water, sewer and access are all adequate to serve the two units on the property. Completion of some of the testing/documentation may be requested to be completed as a condition of approval as a Waiver of Submittals (Section 4-202). The application will still need to address the standards contained in Article 7 (Division I, II, & Ill) and Section 7-701 for Secondary Dwelling Units. Potential waiver requests are noted in the Submittal Checklist and submittal of the current building permit application including site plan details can also serve to address certain submittal requirements. The site plan needs to include significant natural features and important improvements (driveways, water wells, OWTS, and existing structures). The following Sections of the Garfield Land Use and Development Code as amended apply to the Application: ® Section 4-103 Administrative Review and Section 4-101 Common Review Procedures ® Table 4-201 Submission Requirements and Section 4-203 Description of Submittal Requirements. ® Section 4-118 Waiver from Standards and Section 4-202, Waiver from Submittal Requirements, as applicable. ® Article 7 Standards, Divisions I, II, and III, ® Section 7-701 (B), Standards for Secondary Dwelling Units As a convenience outlined below is a list of information typically required for this type of application. Table 4-201 outlines the specific application submittal criteria. The following list can function as a checklist for your submittal. E General Application Materials including the Application Form (signed), payment of Fees and signed Payment Agreement Form (see attached). o A narrative describing the request and related information.

Adjacent Land Use a. Within a1,500-foot radius of the proposed project are developed residential properties, BLM land, and undeveloped property. 2. Site Features a. Topography. The site is located on a west facing hillside above Highway 82, across from the Aspen Glen development. The grade on the property varies from between approximately 15% and 35%. The slope in the area of the proposed ADU footprint is between 20%-30%. There are no known geological hazards in the area of development. b. Vegetation: The proposed location of the ADU is in an existing clearing with sparse plant cover. Around this existing clearing arejuniper and pinyon pine trees, sage brush, grass, and weeds. 3. Soil Characteristics a. Geotechnical report completed for existing dwelling unit indicates that subsoils consist of silty sandy gravel with cobbles and boulders. Report recommended foundations be designed for an allowable soil bearing pressure of 2,000 psf. 4. Geologyand Hazard a. While eastern portions of this 5.63 acre property appear to have been impacted by rockfall and debris flow hazards these are well removed from the proposed area of development. S. Groundwater and Aquifer Recharge Areas a. A Subsurface Investigation and Onsite Wastewater System Design was completed for the existing dwelling. Report indicated that soil in area of proposed development consisted of thin layer of sandy root zone, underlain by sandy silt with gravel and rocks to 8 feet Groundwater or bedrock was not encountered. Based on this existing report a septic system for the ADU with a percolation rate of 20 minutes per inch (MPI) should be achievable. 6. Environmental Impacts a. Flora and fauna: i. Short-term effect As mentioned in "Site Features" section of this impact analysis the proposed development is taking place in an existing clearing with little existing vegetation. We are not proposing the removal of any existing trees. ii. Long term effect: After construction native vegetation will be allowed to regrow in area around the ADU, except where specifically prohibited due to requirements of local fire district. b. Wildlife: I. Proposed development will not impact any critical wildlife habitat. ii. Minimal size of proposed development will ensure minimal impact on wildlife's use of existing land. This development will also not impact further the migration routes or use patterns of wildlife as there is already an existing elk fence on the property line to keep wildlife from crossing Highway 82. c. Radiation hazard does not exist on this property. 7. Nuisance Proposed development will not generate vapor, dust, smoke, noise, glare or vibration, or other emanations that will negatively impact adjacent properties. In addition the ADU was deliberately designed as a "walk -out" style house with most of the mass set into the ground. 8. Hours of Operation a. The proposed development is for construction of accessory dwelling unit. There will be no "Hours of Operation" for commercial or business use that would impact adjacent properties.

In addition to the garage, the owner desires to have the ability to construct a 4-bedroom residence in the future without further modifications to the OWTS. The Site is located outside of Carbondale, in an area where OWTSs and wells are necessary. The northern portion of the Site is currently developed with a single-family residence. A recently installed OWTS serves the single-family residence. A driveway also exists on the northern portion of the Site for access to the single-family residence. A garage with plumbing is proposed on the western portion of the Site. A private well also exists on the Site. The well is located greater than 100-feet from the proposed OWTS that will serve the proposed garage with plumbing. The proposed soil treatment area (STA) location has approximately a twenty percent slope across the proposed STA. Native vegetation such as sage and scrub oak exists in the area of the proposed STA. The subsurface was investigated on August 12, 2014 by digging two 8-foot soil profile test pit excavations (Test Pits) and conducting a visual and tactile evaluation of the soils at approximately 3-feet below native grade. The materials encountered in the Test Pit #1 consisted of medium to dark brown, moist, topsoil to 6-inches, underlain by brownish red sandy loam with single grain structure shape, weak structure grade, and loose consistence with flat, platy cobbles 2 to 4-inches in diameter to a maximum depth explored of 7.5-feet. No bedrock or groundwater was encountered. The materials encountered in the Test Pit #2 consisted of medium to dark brown, moist, topsoil to 6-inches, underlain by brownish red sandy loam with single grain structure shape, weak structure grade, and loose consistence with flat, platy cobbles 2 to 4-inches in diameter to a maximum depth explored of 7.0-feet. No bedrock or groundwater was encountered. Test Pit #1 The proposed garage will include oshower, toilet, and lavatory for use byone person. Wastewater flow, in accordance with Table 6-2 presented in the Garfield County On -Site Wastewater Treatment System Regulations, adopted April 14, 2014, is calculated at 47.9 gallons per day. Since a future, 4-bedroom residence is contemplated, the OWTS design will be based on 4-bedrooms.

Box 11936 Aspen, Colorado 81612 Job No. 110 081A Subject: Observation of Excavation, Proposed Garage/ADU, 5.63 Acre Parcel, North of Mushroom Rock, Highway 82, Garfield County, Colorado Dear Mr. Edelman: As requested, a representative of Hepworth-Pawlak Geotechnical, Inc. observed the excavation at the subject site on March 14, 2014 to evaluate the soils exposed for foundation support. The findings of our observations and recommendations for the foundation design are presented in this report. We previously conducted a pit observation at the site and presented our findings in a report dated May 19, 2010, Job No. 110 081A. Evaluation of potential geologic hazard impacts and possible mitigation are beyond the scope of this study. At the time of our visit to the site, the foundation excavation had been cut in two levels from 1 to 11 feet below the adjacent ground surface. The soils exposed in the bottom of the excavation consisted of medium dense, silty sandy gavel with cobbles and boulders. No free water was encountered in the excavation and the soils were slightly moist to moist. The footings had been formed and steel reinforcement was in place. The soil conditions exposed in the excavation are consistent with those previously encountered on the site and suitable for support of spread footings designed for the recommended allowable bearing pressure of 2,000 psf. The ground surface around the garage/ADU will need to be graded to divert surface flows away from the structure as a minimum in accordance with the Surface Drainage section of our previous report. Other recommendations presented in our previous report which are applicable should also be observed. While on -site, the concrete contractor stated that a rock had fallen into the excavation apparently from the hillside after excavation was complete. The possible rockfall risk had been previously identified as a potential hazard to the site which should be evaluated for possible mitigation. The recommendations submitted in this letter are based on our observation of the soils exposed within the foundation excavation and the previous limited subsurface exploration at the site. Variations in the subsurface conditions below the excavation could increase Pjrk,7 :41 1 I0 • (-1,I..i I �hnne, 1 - rdc,ril . rn, -t .- "', ECOS March 17, 2014 Page 2 the risk of foundation movement.

The review generated the follwviFina comments: 1, The; geotcGhnical report for the residence states that rockiall and debris flow are lil<eiy hazards and would need mitigation. Due to the proximity of the ADU, it is likely diat geologic hazards can be anticipated. The Applicant should obtain a site specific a' eoteclinical study with a geo- hazardanalysis. Mitigation measures may be required and often require walls, fencing, berms or other construction. The Applicant should determine if mitigation may change the proposed ID ADU site location. Minor shifts ftom the proposed ADU location may be acceptable; however shifts of substantial distance may require that the ADU be re -permitted fors a new location. 2. The proposed grading and drainage plan that was submitted was conceptual rather than a detailed plan. Additionally grading, drainage, and retaining structures will be necessary than what was shown. Similarly to the above, the Applicant should determine if these may change the proposed ADU site location. Minor shifts from the proposed ADU location may be acceptable; however shifts of substantial distance rnay1 require that the ADU be rc-permitted for a new location. 3. The water quality anatysis showed poor results for water chemistry. The Applicant will likely need to hire a consultant to design treatment of the well water. 4. Septic design will need to be revised since the number of bedrooms 111 the architectural plans does not match those in the septic calculations.

Our findings are presented in this report. The services were performed in accordance with our I agreement for professional engineering services to you dated January 8, 2018. Background Information: Hepworth-Pawlak Gcotechnical (now HP/Kumar) previously conducted a subsoil study for design of foundations for a residence and ADU at the subject site and presented the findings in a report dated May 19, 2010, Job No. 110 08 IA. The excavation for the residence was observed to evaluate the soils for foundation support on March 14, 2014 and the findings were presented in a report dated March 17, 2014. The residence was completed in 2014. This report addresses the potential geologic hazards in the area of the proposed ADU. We understand the proposed ADU is to be located as shown on Figure 1. We understand the C, geologic hazards review is needed for the submittal to Garfield County, 2, 1=1 Site Conditions: The proposed ADU site is located south of the existing residence. There is a rough graded driveway leading from the main driveway to the proposed ADU site. This driveway will be finished with the construction of the ADU. Vegetation consists of pinon and juniper trees, sagebrush, grass, and weeds. The site is located on a west facing hillside above State Highway 82. The ground slopes down at a grade of about 30 percent in the ADU area. A debris flow several feet thick was previously observed to have knocked down a steel post and wire fence northeast of the current residence site. A deep debris flow channel was observed Caleb Edelman January 12, 2018 Page 2 southeast of the proposed ADU site. There is evidence of damage to trees along the margins of this channel. A recently fallen rock (fresh, relatively unweathered faces and no lichen growth) around 3 feet in diameter was observed lodged behind a tree on the southwest margin of this channel. Multiple smaller debris flow channels were observed to the east of the proposed ADU site, Dead trees and loose boulders were observed in these channels. Maroon Formation bedrock outcrops above the building area on slopes greater than 45 percent. These outcrops are moderately weathered and relatively highly fractured. Fracture spacing ranged from around 3 to 5 feet. Boulders up to around 8 feet in size were observed near the building site. Geologic Hazards Review: Potential major geologic hazards that could impact the site consist of rockfall and debris flow. ��,/,{u�� The rockfall hazard is due to th edrocedf k outcrops above the site and are moderately frequent in the area. Rockfall can damage homes and property when larger rocks fall. Debris flows occur from hillside and mountainside drainages due to heavy rainfall sometimes associated with snow - melt. Debris flows are moderately common along Highway 82 in steep areas within and below the Maroon Formation. The debris flow hazard at the subject site is due to the drainage which currently outlets to the southeast of the site to Highway 82 and the smaller drainages to the east of the site. The subject site is located on a relatively thick debris fan deposit from these drainages. The potential hazards appear to be active geologic processes at the subject site and in nearby areas, and should be expected in the future. However, without long term observations, it is not possible to develop a statistical recurrence probability of the hazards. We are aware of recent debris flows and rockfall in the vicinity of the site. Although the probability that a debris flow or rockfall will impact the proposed ADU is likely low, a debris flow or rockfall has the potential to cause major damage to buildings with a risk of harm'to the occupants. If this risk is not .eceptable to the owgkr, then the feasibility of mitigation should be considered. Rockfall in the area has been mitigated with rockfall catching barriers, and debris flows with soil herons, impact walls, rigid porous barriers, and flexible porous barriers, which may or may not be feasible at the site due to the limited area on the lot behind the proposed ADU and the Bureau of H-PMWMAR Project No. 18-7-104 C:� J3 Caleb Edelman January 12, 2018 Page 3 Land Management property, and the steepness of the terrain. The feasibility of mitigation would need to be evaluated by additional assessments for each potential hazard. Limitations: This review was conducted according to generally accepted geotechnical engineering rinci les and practices in this area at this time:. We make no warranty either express or implied. The conclusions and recommendations submitted in this report are based upon the proposed construction, the grading plans provided to us, our field observations, and our experience in the area.

Our findings were presented in a report dated January 10, 2018, Project No. 18-7-104. This clarification is in response to the email from Dave Argo with Garfield County dated March 13, 2018, item B requesting Geologic Hazards Mitigation Measures. Geologic Hazards Review: Our review was performed to assess potential major geologic hazards that could impact the site which identified rockfall and debris flow. The rockfall hazard is due to the bedrock outcrops above the site. The debris flow hazard is mainly due to the hillside drainage which currently outlets to the southeast of the site and smaller drainages to the east. The subject site is located on a relatively thick debris fan deposit from these drainages. Conclusions: Although the site has been identified as potentially being impacted by rockfall and debris flow, we understand tLa this risk is acceptable. to the. owner and no mitigation measures specific to these hazards are planned. Since the hazard risks are accepted by the owner, additional assessments for mitigation methods are not warranted at this time.

The excavation is presurnably for the planned ADU foundation and was dry at the time ofmyvisit onAugust 29.2O18. An excerpt is presented below from the Geologic Map of the Carbondale Quad- rangle by R. M. Kj[bhG0 and B. L. Widmann of the Colorado Geologic Survey, 2008. Setting and geology of the site can be described as a moderate to very steep hillside above the Roaring Fork River. The Pennsylvanian -age Eagle Valley formation, gray and yellow shale and sandstone comprise the cliffs just above the building site. The slightly more resistant Maroon formation, red bed sandstone and siltstone forms the upper cliffs. Both formations are considered erosion -prone. The project site lies on a thick apron of oo|iuviumandu|npewaahoouroeUinrapid\y-erodingbedrockdiffeabove.Theoo||uv|um deposit is well -exposed in the east wall of the existing foundation excavation shown in Photos 1. 2 and 5 below. The colluvium is a chaotic mixture of tabular sandstone boul- ders in a silty and sandy clay matrix and appears to be the result of ancient MUcIflow off the hillside above. The reasonably well-defined topsoil layer exposed at the top of the excavation indicates the recurrence interval of mudflows that formed these slopes is probably hundreds of years or more, Observations of the ground surface around the ex- isting residence and ADU area indicated shallow drainage swales with no evidence of erosive flow.

Mitigation to maintain relatively |ovv MUSHROOM ROCK PARTNERSHIP, uo ^ouxr1m11HIGHWAY ox PROJECT woGSe��0-105 risk would include regular inspectionand maintenance of the ditches to prevent them from overflowing above the existing residence orproposed &DU. A civil engineer with expertise in surface water hydrology can assist to determine the design flood and ability of the existing drainage ditches to carry the flow. Our brief observations indicate the ditches have carried significant flow inrecent years. Potentially Unstable Slopes Slopes well -above the project oitebeconnn progressively steeper toward the Ma- roon formation sandstone cliffs at the top of the mesa. These slopes are erodible and somewhat unstable. Water erosion, chemical weathering and gravity contribute to risk of slope instability. Our observations indicated no evidence of an existing or incipient land- slide that could affect the ADU,The current good drainage inthe site ofthe /\DUand rel- atively dry climate reduce the risk that unstable S|0pRs will affect the project. K8@ea wast- ing due to erosion is the most serious slope instability risk on this site. To the extent that the site remains relatively dry, risk ofunstable slopes is low. Photo 2 shows avertica| ex- cavation in the colluvium that has stayed stable for the years it has remained open. Miti- gation for potentially unstable slopes does not appear to be necessary for construction of theA[)U. Seismic Effects The site isexposed torisks due tOseismicity. This part nfColorado has alow risk ofseismic movements that could damage residential construction. Faults near the pro- ject site are thought to be inactive and are related to mountain building episodes that are many millions of years old. There is increased risk of some of the above -mentioned geo- logic hazards during seismic events, but there is no need for mitigation compared to sim- ilar sites in the area. Summary In summary, the site is exposed toolow risk of geologic hazards. None of the identified risks require mitigation. The capacity of the incised drainage ditches north and south ofthe /\DUshould heevaluated with respect hnthe design Oood. This will help you determine the risk mfflooding.
