Garfield County Environmental Health, Morgan Hill (Exhibit 11): Supported the recommendations from HP Geotech regarding the design, operation, and maintenance of the septic system, required a water quality test that is equivalent to CDPHE Deluxe Colorado Package, and recommended that a radon test be performed. VI. STAFF ANALYSIS Article 7, Division l: 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 rural zone district. The property currently has one dwelling unit on the property. The proposed ADU will be the second permitted dwelling unit on the property, which is permitted with Administrative Approval. Based on the submitted site plan documents and engineering reports, it appears that all structures meet required setbacks. 2. Section 7-102: Conformance with Comprehensive Plan and compliance with lGAs The County Comprehensive Plan identifies the property as Residential Low which provides a suggested density of one unit per l0 acres. As the property is 54.717 acres, the residential density identified within the Comprehensive Plan would be satisfied including the ADU. 3. Section 7-103: Compatibility The proposed use is located in a rural area and is unlikely to significantly alter or impact the character of the area. The areas surrounding the subject property are predominantly residential. The ADU will be located in an already existing structure. 5 4. Section 7-104: Sufficient, Adequate, Legal and Physical Source of Water The ADU is to be served by the existing well on the property. The applicant has indicated that the parcel will be served by well number 296853. However, state records show that this permit no. is for a monitoring well. Well 81 176-F is shown by Division of Water Resource records as a permitted well on the property, in conjunction with well14224-A' 81176-F allows for a single fami$ dwelling and well permit 14224-A allows for up to 3 single-family dwelling units. lt is staffs understanding that the ADU will be served by well 81176-F. The application and well permits were reviewed by the Division of Water Resources. Their response stated (Exhibit 6): As tong as the uses of fhe well do not exceed those allowed under the permit, this office has no objection to the well also seruing the proposed ADU. As part of the application, the applicant requested that the required water quality test be a condition of approval. Since no water quality information has been provided, staff has included a suggested condition of approval that the applicant provide a water quality test and if needed complete treatment. Garfield County Environmental Health and the County designated engineer both supplied referral comments recommending a water quality test. The applicant did submit a 4-hour pump test that was completed in 2015.|t was reviewed by the County Designated Engineer who stated: The pump results show that the wellwas drawn down to 130' of its 140' estimated depth. The Mancos formation is a notoriously poor formation for water conductivity. No information was given on the water level recovery in the well. The Applicant shoutd determine how tong it takes for the aquifer to recover to the static water Ievel in the wett and to verify the pump rate is compatible with the aquifer production. Staff has included a suggested condition of approval that the applicant provide information on the adequacy of the pump test that is reviewed and accepted by the County designated engineer. S. Section 7-105: Adequate CentralWater Distribution and Wastewater Systems The Applicant has installed an Onsite Wastewater Treatment System that does not have a completed permit with Community Development. The application included an engineering report for the system as well as photos of the installation. No comments were geñerated from the designated County Engineer's Review. Staff has included as a ıuggested condition of approval that the applicant obtain an OWTS permit for the system. 6 6. Section 7-106: Adequate Public Utilities The applicant has represented that adequate public utilities exist to the structure. 7. Section 7-107: Access and Driveways a. The application was referred to the Garfield County Road and Bridge Department (See Exhibit 8). Mike Prehm of Garfield County Road and Bridge indìcated Road and Bridge has no concerns with the proposed ADU. He indicated that the driveway access onto the County Road meets all current requirements and that no permits are required from Garfield County Road and Bridge' b. The property is served directly off of County Road 1 17. c. The Applicant has stated that the existing driveway meets the design standards found in Table 7-107. The application was reviewed by the Garfield County designated engineer, who did not indicate any issues with the access. 8. Section 7-108: Natural Hazards Slopes are identified as a natural hazard on the property, however the slopes are located on ihe other side of the creek from the location of the already established building. The lot is not located in a FEMA mapped floodplain, however floodplain mapping was required as part of the submittal for the single-family house on site. As indicated on the site plan, the existing garage and OWTS is located close to 4-Mile Creek. As part of the ADU application process, the applicant submitted a floodplain analysis from a certified engineer, it stated: Based on the ftow depth calculations, the building appears to be protected from the 117-year ftood ftow. The suruey of the OWTS seepage field indicates that it is more than two feet above the adjacent 1)}-year flood plain. Also, based on the suruey, the two buitding corners adjacent to the creek complies with the minimum 35 foot distance from the creeks normal high water mark. This application was referred to the County designated engineer. His review of the mate¡als generated no comments. lt is staff's opinion that the applicant's engineer has demonstrated that the structure is located outside of the floodplain and at least 35-feet away from the Typical and Ordinary High Water Mark of 4-Mile Creek. Staff has included a "ondition of apþroval that at the time of building permit, the applicant shall provide a site plan that shows all development will be located outside of the 35-foot setback. The parcel is located in an area identified as having septic system constraints by Garfield County Hazard Mapping. This usually triggers a requirement for an engineered OWTS. The aþplicant has already installed an engineered system, but still needs to obtain a permit from the CountY. 9. Section 7-109: Fire Protection 7 The application was referred to the Glenwood Springs Fire Department. Their referral comments indicated possible issues with access to the property via the existing gate, a determination of if the pond will be usable for firefighting, and a needed assessment of the site for possible wildfire hazard fuels. Staff has included a suggested condition of approval that the applicant meet with the Glenwood Springs Fire Department and provide a demonstration that they have met their requirements. Article 7, Division 2: General Resource Protection Standards 10. Section 7-20l Agricultural Lands The proposed development is not anticipated to impact any agricultural activity on or adjacent to the site. Ditches were located on the property, however contact information for both the Moda and the Buck Enlargement appeared to not be current. The applicant provided research indicating that the contact information for the ditches may no longer be accurate. Staff called a phone number that was used as contact information by the Division of Water Resources and the number was no longer in service. Discussions with the Division of Water Resources indicated that the records for who currently owned the ditch may not be up-to-date. As such, the application was not sent out to the ditch companies for referral. Additionally, the ADU will be located in an already permitted structure with an already established access. Staff does not anticipate any impact on any ditches on the property from the ADU. 11. Section 7-202 Wildlife Habitat Areas The application was submitted to Colorado Parks and Wildlife for referral comments. They responded with recommendations to reduce bear/human conflict and human/moose conflict. Those concerns are specifically listed in Exhibit 10. Staff has included a suggested condition of approval that the applicant abide by the recommendations in the Parks and Wildlife letter. 12. Section 7-203 Protection of Waterbodies The building where the ADU would be located is in close proximity to 4-Mile Creek. The applicant supplied an assessment from an engineer stating that: "Also, based on the survey, the two building corners adjacent to the creek complies with the minimum 35 foot distance from the creeks normal high water mark." The engineer's report was reviewed by the County designated engineer and no comments were generated. lt is staffs opinion that based on the engineering report the existing building meets the 35 foot water body setback. Staff has included a suggested condition of approval that at the time of building permit the applicant supply a site plan showing all proposed improvements are located outside the 35 foot waterbody setback. 8 A site visit showed that there may have been some potential grading within the 35 foot setback when the structure was built. Grading or removal of vegetation is not permitted within the 35 foot waterbody setback. Staff has included a suggested condition of approval that requires the applicant to revegetate this area with a seed mix acceptable to Garfield County Vegetation Management. 13. Section 7-204 Drainage and Erosion The Applicant has provided a topographic map of the subject property that shows general positive drainage around the proposed ADU. The application was reviewed by the Garfield County engineer and no comment was received. At the time of Final Inspection, the structure will be checked for positive drainage by Building Inspectors. 14. Sections 7-205 Environmental Quality No water or air quality issues are anticipated from the proposed project. 15. Section 7-206 Wildfire Hazards The Wildland Fire Susceptibility Index of the Community Wildfire Protection Plan designates the property as mostly Very High, with a small area of high wildfire suscêptibility. There are significant slopes on the site, however these are mostly limited to the area on the other side of 4-Mile Creek from the ADU structure. The application was reviewed by the localfire district, who indicated (Exhibit 9): The site wilt need to be assessed by Glenwood Springs Fire Department staff to determine if some mitigation of wildfire hazard fuels r's need to improve the defensible space around the structure or structures. Staff has included a suggested condition of approval that the applicant fulfill Glenwood Springs Fire Department comments. 16. Section 7-207 Natural and Geologic Hazards See analysis of 7-108 for a discussion of natural hazards on the property 17. Section 7-208 Reclamation Minimal disturbance is anticipated as a result of the proposed ADU, as it will be located inside an existing building. Garfield County Vegetation Management provided a referral comment that requested the applicant provide a weed management plan for the site. After referral comments, Steve Anthony of the Vegetation Management Department, completed a site visit with Community Development Staff. During that visit he noted some weeds on the property located to the south of the structure. Mr. Anthony indicated that a condition of approval would be appropriate that the applicant monitor that area and 9 manage weeds on the site. This has been included as a suggested condition of approval. Article 7, Division 3, Site Planning and Development Standards 18. Section 7-301 Compatible Design: The ADU use is generally compatible with surrounding residential 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 Land Use and Development Code 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 over 4 acres, the ADU is required to be limited to 3,000 square feet. Staff suggests a condition of approval that the ADU be limited to 3,000 square feet or less in size. 25. OwnershipRestriction: 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. 26. Compliance with Building Code: 10 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 54.7 acres and as a result the minimum lot area requirement of at least 2 acres in the Rural 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 as it exists will comply with this standard. VII. SUGGESTED FINDINGS AND RECOMMENDATION Staff recommends a finding that 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 Chapman ADU application. Suggested Findings 1.

The review generated the following comments: 1. Water quality testing as a condition of approval may rrequire water treatment depending on results. 2. The pump results show that the well was drawn down to 130' of its 140' estimated depth. The Ma¡cos fonnation is a notoriously poor formation for water conductivity. No infonnation was given on the water level ïecovery in the well.

The Holmes property is located within etk winter range, btack bear fatl concentration area, and moose concentration area. Overall CPW has few concerns related to the addition of an ADU within the existing garage due to the existing disturbance. However as this area is known to have black bear confticts and the moose population within the area is growing, CPW offers the following reiommendations to reduce potentiaI for human/witdtife conflicts: 1. Bear/human conflicts have the potential to be a reoccurring probtem in this area and it is important that certain measures be taken to minimize these confticts: . Homeowners have and use an approved bear-proof container for storing atl trash/garbage.. Pets shoutd be fed indoors, and pet food or food containers shoutd not be left outside.. BBQs shoutd atso bå securety housed in the garage or cleaned with a'bteach sotution when not in use due to the fact that leftover food and grease are an overwhetming bear attractant. 2. Human/moose confticts atso have the potential to increase as the existing moose poputation grows. Residents shoutd be aware of the potential for conftict and take precautions to avoid them. Dogs running toose are a major catalyst for conftict with moose becoming very aggressive towards dogs which they view as a threat. Dogs shoutd be kenneted and not altowed to run free without immediate supervision. Bob D. B¡ccheid, Dìßcbr, Cohñdo Pa¡|a ild WiHliÈ . k*s Ând WiHliË Co¡rvnissio¡: Robst W.
