The address is 6698 Highway 82, Glenwood Springs, CO 81601. Section: 1 Township: 7 Range: 89 TR IN LOT 8 known by Assessor's Parcel No. 239501100017. ACRES Approximately 1.197 acres ZONING Commercial Limited (CL) I. DESCRIPTION OF THE PROPOSAL The Applicant is requesting a permit for an Accessory Dwelling Unit (ADU) on a 1.197 acre parcel located within the Commercial Limited (CL) zone district. The property is over the 15,000 square foot minimum lot size for an ADU in the CL zone district (2x minimum Lot Size of 7,500 sq ft). As the property is under 4 acres, however, the ADU is limited to 1500 square feet. The Garfield County Comprehensive Plan of 2030 identifies the property as Mixed Use (2 — 12 dwelling units per acre). Access to the site is an existing driveway and private roadways from State Highway 82. The site has adequate areas for off-street parking and snow storage for the proposed ADU and other existing uses on the property. The proposed ADU is to be located above a detached garage. An existing water well, existing shared private access drive, and a new Onsite Wastewater Treatment System (OWTS) have been proposed to serve Accessory Dwelling Units. II. DESCRIPTION OF THE SITE The property is located approximately 4 miles south of the City of Glenwood Springs and within the Mixed Use designation with the Comprehensive Plan. The property is accessed off a private access road from State Highway 82. Uses within 1500 feet include primarily residential and commercial. The property currently has a primary dwelling unit built in 1973.

WAIVER REQUESTS FROM STANDARDS The Applicant has requested a Waiver from Section 7-107 related to Roadway Standards. IV. AUTHORITY — APPLICABLE REGULATIONS A. The Land Use Tables contained in Section 3-403 of the Land Use and Development Code, designates an Accessory Dwelling Unit within the Commercial Limited zone district as requiring Administrative Review. B. Section 4-103 of the Land Use and Development Code sets forth the Administrative Review Procedures by which the current Application is being considered. C. The Application submittal requests two waivers from submittal requirements. These waiver requests are from submittal requirements included an improvements agreement and development agreement. Submittal waivers have been accepted as part of the completeness review. D. Article 7 of the Land Use and Development Code sets forth General approval standards in Division 1, General Resource Protection Standards in Division 2 and Site Planning and Development Standards in Division 3. Accessory Dwelling Units are also subject to Section 7-701. The standards are addressed in the Application submittals and in the Staff Analysis section of the Staff Report. V. PUBLIC AND REFERRAL COMMENTS The Applicant has provided documentation that all required notice mailings have been completed in accordance with the LUDC. No public comments were received as a result of the public notice. Public and referral comments received on the Application are attached as Exhibits and summarized below: A. Garfield County Consulting Engineer, Chris Hale, Mountain Cross Engineering (Exhibit 7): 1. The Applicant proposes to obtain a permit for an onsite wastewater treatment system (OWTS) after approval for the ADU is obtained. However the lot is small (less than an acre), there is an existing well, an existing OWTS, adjacent houses, and there are likely issues with evaporate soil. The Applicant should obtain soils tests, determine existing OWTS locations, and obtain a design from a qualified professional to verify that an OWTS is feasible on the lot. The Applicant should also review section 7-105.B.2.b of the Land Use Development Code (LUDC). 2. There is an existing drainage from the hillside above that drains adjacent 5 to the lot. The Applicant should evaluate 7-203 of the LUDC and verify that applicable setbacks from a waterbody have been achieved. 3. Drainage and erosion may be an issue and the Applicant should reevaluate sections 7-204.6 and 7-204.0 of the LUDC in light of this existing drainage way. The Applicant may need to seek the recommendations of a qualified professional. 4. By nature the steep hillside and drainage would likely cause natural and geologic hazards. The Applicant should hire a qualified professional to verify whether or not the hazards identified in section 7-207 of the LUDC exist. Mitigation may be required. B. Garfield County Road and Bridge (Exhibit 4): Road and Bridge has no concerns with the request. C. Colorado Department of Transportation (CDOT) (Exhibit 3): CDOT noted that they have no comments on this application. D. Colorado Parks and Wildlife (CPW) (Exhibit 5): CPW noted that "During construction CPW recommends that all garbage should be kept in bear -proof containers and disposed of on a regular basis." E. Colorado Division of Water Resources (DWR) (Exhibit 6): DWR noted that "The applicant's proposal indicates that the well currently serves a single family residence. The proposed ADU would be considered, for the purposes of well permitting, to be an additional single family dwelling. As long as the uses of the well do not exceed those allowed under the permit, in particular no more than one single family dwelling and one accessory dwelling unit, this office has no objection to the well also serving the proposed ADU." VI. STAFF ANALYSIS Article 7, Division 1: General Standards 1. Section 7-101: Compliance with Zone District Use Regulations The development on the property is in general conformance with the dimensional standards for the Commercial Limited zone district. All future construction must comply with the Commercial Limited zone district standards as well. Final compliance with these standards related to the ADU will be determined at the time of building permit. 2. Section 7-102: Conformance with Comprehensive Plan and compliance with IGAs The County Comprehensive Plan identifies the property as Mixed Use (2-12 dwelling units 6 per acre). As the total density would be approximately 2 dwelling units per acre, it is Staff's opinion that the ADU is in general conformance with the goals and objectives of the Comprehensive Plan. 3. Section 7-103: Compatibility The proposed use is located in a mixed use commercial and residential area at the intersection of County Road 114 and State Highway 82. The ADU is not expected to adversely impact the character of the area as the ADU is proposed to be located on the second floor of a new garage. 4. Section 7-104: Sufficient, Adequate, Legal and Physical Source of Water The ADU is to be served by an existing well on the property. This well, Permit Number 82152-F, states that "The use of ground water from this well is limited to ordinary household purposes inside one (1) single family dwelling, one (1) accessory dwelling unit, the irrigation of not more than 5,000 square feet of home gardens and lawns." As a result of this language, it appears that the well is legally able to serve both the primary and accessory dwelling units. The application was referred to the Division of Water Resources who noted that "The applicant's proposal indicates that the well currently serves a single family residence. The proposed ADU would be considered, for the purposes of well permitting, to be an additional single family dwelling. As long as the uses of the well do not exceed those allowed under the permit, in particular no more than one single family dwelling and one accessory dwelling unit, this office has no objection to the well also serving the proposed ADU." Water quantity testing revealed that the well averaged 14.2 gallons per minute over the 4 hour pump test. The pump test, which was conducted on January 24, 2018 by J&M Pump Inc., provided the following statement: "The well production indicates adequate water for three houses using 300 gallons each per day." As a result of this pump test, the water quantity appears to be adequate to serve both the primary and Accessory Dwelling Unit. The water quality of the well met applicable EPA standards. As a result, the well appears to meet this LUDC standard. 5. Section 7-105: Adequate Central Water Distribution and Wastewater Systems The Applicant is proposing to install a new Onsite Wastewater Treatment System (OWTS) for the proposed ADU. Referral comments from the County designated engineer noted that "the lot is small (less than an acre), there is an existing well, an existing OWTS, adjacent houses, and there are likely issues with evaporate soil. The Applicant should obtain soils tests, determine existing OWTS locations, and obtain a design from a qualified professional to verify that an OWTS is feasible on the lot." A discrepancy in property size was noted between the County Assessor's records and the applicant 7 provided a survey. Based on discussions with the County Assessor's Office and representations from the applicant, it appears that the property is 1.197 acres, not .075 acres as identified in the Assessor's records. As a result, the property is in fact greater than 1 acre and an OWTS is allowed. In addition, since the lot appears to have been created prior to subdivision regulations by the County, the Code allows for consideration of the issuance of an OWTS on this parcel regardless. Due to the other issues identified by the County designated engineer, however, staff recommends that the OWTS that is installed for this ADU be engineered. As a result, Staff recommends a condition that the property owner have the OWTS designed by an engineer and obtain an OWTS permit at the time of construction of the ADU. 6. Section 7-106: Adequate Public Utilities Adequate public utilities currently exist at the subject parcel. 7. Section 7-107: Access and Driveways a. The application was referred to the Garfield County Road and Bridge Department (See Exhibit 4). Mike Prehm of Garfield County Road and Bridge indicated Road and Bridge has no concerns with the proposed ADU. b. The application was referred to the Colorado Department of Transportation (CDOT) (Exhibit 3) indicating that, while the access to Highway 82 is not ideal, CDOT has no concerns with the proposed ADU. c. The Applicant has stated that the driveway and private access road do not meet the design standards found in Section 7-107 for the determined traffic levels. The applicant has provided an engineer statement and analysis of the roadway with the conclusion that "Although the roadway does not meet the dimensional standards outlined in Section 7-107, it is still adequate to serve the proposed use." Based on this engineer statement, it is Staff's opinion that private access roadway is physically adequate. d. Legal access for the private roadway to the property is demonstrated via an easement recorded at Reception Number 254066. While the width of the easement is 30' and Section 7-107 requires an easement width of 50', based on the provided engineer's statement regarding the adequacy of the roadway, it is Staff's opinion that the roadway width is adequate and that legal access is available to the proposed use. 8. Section 7-108: Natural Hazards Comments from the County designated engineer indicate that "By nature the steep hillside and drainage would likely cause natural and geologic hazards. The Applicant should hire a qualified professional to verify whether or not the hazards identified in section 7-207 of the LUDC exist. Mitigation may be required." As a result of these 8 comments, Staff recommends that a geo-hazards study be conducted by a qualified professional to evaluate hazards created by the steep hillside and drainage. Any recommended mitigation measures as a result of this study are recommended to be installed prior to issuance of the Land Use Change Permit. 9. Section 7-109: Fire Protection The impact area within the subject parcel has been identified as having a Very High level of Wildfire Susceptibility in accordance with Map 7 of the Community Wildfire Protection Plan. The parcel is located within the Carbondale Fire Protection District service area. The application was referred to the Carbondale Fire Protection District, however, no comments were received. As the wildfire hazard is considered Very High, Staff recommends a condition of approval based on the requirements of the Code that the roof materials for the ADU structure be comprised on noncombustible materials. Article 7, Division 2: General Resource Protection Standards 10. Section 7-201 Agricultural Lands The proposed development is above an existing garage on the subject property. It is not anticipated that the proposed development would adversely affect neighboring agricultural uses or agricultural uses on the subject parcel. 11. Section 7-202 Wildlife Habitat Areas As the ADU is proposed to be located above an existing garage, wildlife impacts are expected to be minimal and similar to those associated with a single family residence. As a result, no significant impact to wildlife habitat is expected. Comments from the Colorado Parks and Wildlife (Exhibit 5) noted that "During construction CPW recommends that all garbage should be kept in bear -proof containers and disposed of on a regular basis." Staff recommends that the applicant comply with this recommendation. 12. Section 7-203 Protection of Waterbodies As represented, the garage where the ADU is to be located is more than the required 35 feet from an ordinary high water mark associated with a Waterbody as defined in the LUDC. Comments from the County designated engineer (See Exhibit 7) state that "There is an existing drainage from the hillside above that drains adjacent to the lot. The Applicant should evaluate 7-203 of the LUDC and verify that applicable setbacks from a waterbody have been achieved." As a result, Staff recommends a condition of approval that prior to issuance of the Land Use Change Permit the applicant shall have a geo-hazards study conducted to verify that applicable setbacks from the waterbody will be satisfied. 9 13. Section 7-204 Drainage and Erosion The Applicant has provided a topographic map of the subject property that shows general positive drainage from the property. Comments from the County designated engineer, however, state that (See Exhibit 7) "Drainage and erosion may be an issue and the Applicant should reevaluate sections 7-204.B and 7-204.0 of the LUDC in Tight of this existing drainage way. The Applicant may need to seek the recommendations of a qualified professional." As a result of these comments, Staff recommends a condition of approval that prior to issuance of the Land Use Change Permit the applicant shall have a geo-hazards study conducted by a qualified professional to evaluate any drainage and/or erosion issues related to the requirements of Section 7-204. 14. Sections 7-205 Environmental Quality No water or air quality issues are anticipated from the proposed project. Impacts to water and air quality are expected to be minimal and similar to those associated with a single family residence. 15. Section 7-206 Wildfire Hazards The impact area within the subject parcel has been identified as having a Very High level of Wildfire Susceptibility in accordance with Map 7 of the Community Wildfire Protection Plan. In addition, no slopes over 30% have been identified and no fire chimneys are known to exist on the property. The parcel is located within the Carbondale Fire Protection District service area. The application was referred to the Carbondale Fire Protection District, however, no comments were received. As the wildfire hazard is considered Very High, Staff recommends a condition of approval based on the requirements of the Code that the roof materials for the ADU structure be comprised on noncombustible materials. 16. Section 7-207 Natural and Geologic Hazards Comments from the County designated engineer indicate that "By nature the steep hillside and drainage would likely cause natural and geologic hazards. The Applicant should hire a qualified professional to verify whether or not the hazards identified in section 7-207 of the LUDC exist. Mitigation may be required." As a result of these comments, Staff recommends that a geo-hazards study be conducted by a qualified professional to evaluate hazards created by the steep hillside and drainage. Any recommended mitigation measures suggested by this study are recommended to be installed prior to issuance of the Land Use Change Permit. 17. Section 7-208 Reclamation Minimal, if any, new disturbance is anticipated as a result of the proposed ADU. The driveways are in place and the structure is to be constructed within an already disturbed area. 10 Article 7, Division 3, Site Planning and Development Standards 18. Section 7-301 Compatible Design: It is Staff's opinion based on representations in the application and since the residential ADU is to be located above a new garage that this residential use is generally compatible with surrounding residential and commercial land uses. 19. Section 7-302 Off- Street Parking and Loading Standards: The Applicant has demonstrated through site plans that adequate off-street parking exists for the ADU and primary dwelling unit. 20. Sections 7-303 Landscaping Standards: The LUDC specifically exempts ADUs from Section 7-303. 21. Section 7-304 Lighting: Staff recommends a condition of approval that any exterior lighting comply with the Standards outlined in Section 7-304. 22. Section 7-305 Snow Storage Standards: The property has adequate snow storage areas that are in compliance with County standards. 23. Section 7-306 Trail and Walkway Standards: No recreational or community facility access areas are proposed. Article 7, Division 7, Accessory Dwelling Unit 24. Maximum Floor Area: As the property is under 4 acres, the ADU is required to be limited to 1,500 square feet. Staff suggests a condition of approval that the ADU be limited to 1,500 square feet or less in size. 25. Ownership Restriction: The Applicant and Owner understand that the ADU is restricted to leasehold interests and may be used for residential or Home Office / Business use only. 11 26. Compliance with Building Code: Staff recommends a Condition of Approval requiring the Applicant to obtain all necessary building permits from Garfield County. 27. Minimum Lot Area: The Applicant has 1.197 acres and as a result the minimum lot area requirement of at least 15,000 square feet in the Commercial Limited zone district is satisfied. 28. Entrance to Dwelling Unit: The Applicant is proposing the ADU to be a separate building from the primary dwelling unit. As a result, the ADU will comply with this standard. VII. SUGGESTED FINDINGS AND RECOMMENDATION Staff recommends a finding that, with acceptance of the proposed Waivers, the proposed Accessory Dwelling Unit is in conformance with the Comprehensive Plan of 2030 as well as the Land Use and Development Code. Staff, therefore, recommends approval with conditions of the Nelson / Brumby ADU application. Suggested Findings 1. That proper public notice was provided as required for the Administrative Review Land Use Change Permit. 2. That with the adoption of conditions and Waivers to Section 7-107, Access and Roadways, the application is in general conformance with the 2030 Comprehensive Plan, as amended. 3. That with the adoption of conditions, the application has adequately met the requirements of the Garfield County Land Use and Development Code of 2013, as amended. Suggested Conditions of Approval Conditions to be Satisfied Prior to Issuance of the Land Use Change Permit: 1. Prior to issuance of the Land Use Change Permit the applicant shall have a geo- hazards study conducted by a qualified professional. Any recommended mitigation measures suggested by this study shall be installed prior to issuance of the Land Use Change Permit.

The proposed project area falls within low quality wildlife habitat. The areas surrounding the property are currently developed. Based on the existing impacts in the area, impacts to wildlife from the proposed project will be minimal. CPW offers the following best management practices to avoid conflicts with wildlife: 1.

No. 950431 EXHIBIT Date: June 13, 2018 To: David Pesnichak, Garfield County Community Development Department From: Justina P. Mickelson, Physical Science Researcher Scientist Re: Nelsen / Brumby Accessory Dwelling Unit; GAPA-02-18-8609 We have reviewed the proposal to construct a garage with an Accessory Dwelling Unit (ADU) on a parcel of approximately 1.197 acres in size, located in part of Section 1, Township 7 South, Range 89 West of the 6th P.M, at 6698 Highway 82, Glenwood Springs. The property currently has an existing single family residence, access road and utilities in place. The applicant does not propose to create a new lot or change the size of the existing lot. The current water supply to the parcel is provided by an existing well and the applicant proposes a new septic system for the ADU. According to the applicant's submittal, well permit no. 82152-F services the existing residence and will service the proposed ADU. Well permit no. 82152-F was issued on June 7, 2018 for an expansion of use of an existing well to operate in accordance with one or more of the Basalt Water Conservancy District augmentation plans, and located in the SE% of the NE1/4 of Section 1, Township 7 South, Range 89 West of the 6th P.M. The use of groundwater from the well is limited to ordinary household purposes inside one single family dwelling, one accessory dwelling unit, and the irrigation of not more than 5,000 square -feet of home gardens and lawns. The annual withdrawal of ground water shall not exceed 0.98 acre-foot and the pumping rate shall not exceed 15 gpm. According to the Statement of Beneficial Use received May 1, 1987, the well had been constructed and put to beneficial use. The permit is valid for those uses listed above. The applicant's proposal indicates that the well currently serves a single family residence. The proposed ADU would be considered, for the purposes of well permitting, to be an additional single family dwelling. As long as the uses of the well do not exceed those allowed under the permit, in particular no more than one single family dwelling and one accessory dwelling unit, this office has no objection to the well also serving the proposed ADU. Please feel free to contact me at 303-866-3581 if you or the applicant has any questions. o 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www.water.state.co.us 'N' \876; 9 0 June 19, 2018 Mr. David Pesnichak Garfield County Planning 108 8th Street, Suite 401 Glenwood Springs, CO 81601 MOUNTAIN CROSS ENGINEERING, INC. Civil and Environmental Consulting and Design RE: Nelson-Brumby Accessory Dwelling Unit: GAPA-02-18-8609 Dear David: h a a EXHIBIT This office has performed a review of the documents provided for the Nelson and Brumby ADU Application. The submittals were found to be thorough and well organized. The review generated the following comments: 1. The Applicant proposes to obtain a permit for an onsite wastewater treatment system (OWTS) after approval for the ADU is obtained. However the lot is small (less than an acre), there is an existing well, an existing OWTS, adjacent houses, and there are likely issues with evaporate soil. The Applicant should obtain soils tests, determine existing OWTS locations, and obtain a design from a qualified professional to verify that an OWTS is feasible on the lot. The Applicant should also review section 7-105.B.2.b of the Land Use Development Code (LUDC). 2. There is an existing drainage from the hillside above that drains adjacent to the lot. The Applicant should evaluate 7-203 of the LUDC and verify that applicable setbacks from a waterbody have been achieved. 3. Drainage and erosion may be an issue and the Applicant should reevaluate sections 7-204.B and 7-204.0 of the LUDC in light of this existing drainage way. The Applicant may need to seek the recommendations of a qualified professional. 4. By nature the steep hillside and drainage would likely cause natural and geologic hazards. The Applicant should hire a qualified professional to verify whether or not the hazards identified in section 7-207 of the LUDC exist. Mitigation may be required.
