The percolation test holes and soil profile hole locations are shown on the attached sketch. Based on our analysis, the average percolation rate for design purposes is 36 minutes per inch. This value is within the acceptable range for a conventional ISDS abaurption system. The soil profile shows 12 inches of topsoil, 3 feet of clayey sand and gravel with plant roots, and clayey silty sand and gravel with cobbles in the lower 6 feet of the profile hole. Them was no groundwater at the excavated depth of 10 feet. A copy of the field data sheets are attached. Based on the data above, the County will size the lcachfield system. We recomcnCucl installation of a graveless infiltrator -type leachfield system for ease of construction and longer service life. Please call if you have any questions or need additional information.

SITE DATA: The lot is essentially flat and is located between Snowmass Creek and Snowmass Creek Road. There is an existing residence and outbuilding on the property. The proposed structures are located outside of the required yard setbacks. BACKGROUND: A red tag was issued by the Zoning Officer on December 1, 1994, for earthmoving activity without a permit. Alan Czenkusch of the Colorado Division of Wildlife and Mike Claffey of the U.S. Army Corps of Engineers both visited the property to assess the impact of the earthmoving on the floodplain and the riparian area on the property. WATER AND SEWER: Information was not provided by the applicants concerning water and sewer for the existing residence or the proposed barn and shed. The Environmental Health Department (EHD) makes the following comments (attached): a. Information shall be provided to the EHD stating the proposed use of water for the barn, particularly whether water is to be used for human consumption, and, if required, documenting the location of the well and the quality and quantity of water obtained from the well. b. The floor plan for the barn shows floor drains for the horse stalls. A no -fee septic permit can be obtained from the EHD if there will not be a bath/lavatory in the barn. Otherwise, a septic permit will be required. The septic system shall be located a minimum of 50 feet from the high water mark (500 year floodplain line on the site plan) of Snowmass Creek and shall. avoid areas of groundwater. 1 f 44 REQUEST: The applicants request administrative 1041 Hazard Review approval to construct an equipment shed and a barn. The site is encumbered by low wildfire hazard, the Snowmass Creek floodplain and riparian area. STAFF COMMENTS - 1041 REVIEW Wildfire The property is mapped in a low wildfire hazard area, though it is located adjacent to Snowmass Creek in a riparian area. Since the site was not determined to be in a "no" wildfire hazard area, the applicant will be required to comply with the standards in Section 3-807(C) of the Land Use Code. These requirements are included in the conditions of approval. Kelly Rogers of the Colorado State Forest Service states, "The combination of low hazard fuels, close proximity to a fire station, and adequate road and driveway access make this proposal a very low risk from wildland fire." The property is serviced by the Basalt Fire District from the Snowmass substation. No comments were received from the Sheriff or the Basalt Fire District. Floodplain The property is_ encumbered by the Snowmass Creek floodplain. Section 3-804 of the Land Use Code prohibits development within the 100 year floodplain. The site plan provided by the applicant depicts the 500 year floodplain line, and the proposed structures are located outside of this area. The applicant noted in the meeting that the floodplain line is not accurate, and that the area where the improvements are proposed is above the creek (outside of the floodplain) and on a level with the rest of the property. The applicant shall revise the site plan to accurately depict the 100 year floodplain line, which would be less restrictive than the line shown on the site plan. Tom Newland, Pitkin County Floodplain Administrator, notes that County floodplain permits will not be required because the structures are outside of the 100 year floodplain area. The applicants shall be required to establish a building envelope to encompass the proposed barn and shed, as well as the "horse area" shown on the site plan. The envelope shall be located at least 20 feet from the 100 year floodplain line. All development shall occur within this envelope. E Alan Czenkusch, Colorado Division of Wildlife, and Mike Claffey, U.S. Army Corps of Engineers, have visited the site and determined that the proposed location of the shed and the barn will not impact the riparian area along the creek. Mr. Woodrow has agreed to comply with any conditions imposed by the DOW and the Corps of Engineers, including restoring the vegetation along the bank that was disturbed. FINDINGS: 1. The wildfire hazard can be mitigated. 2. The proposed barn and equipment shed avoid the Snowmass Creek floodplain and the riparian areas along the creek. RECOMMENDATION: Pursuant to Section 3-801(8)(2) of the Land Use Code, the Hearing Officer is authorized to approve a site plan and application for a Minor 1041 Hazard Review. Based on the findings referenced above, Staff recommends approval of the Woodrow Minor 1041 Hazard Review. Said approval is subject to the conditions of approval listed below. This memo will serve as a reference document authorizing approval of said application. The Hearing Officer's sign -off on a 1041 Hazard Review Site Plan is also necessary for completion of the review process. The Site Plan shall be recorded in the Clerk & Recorder's office, and a copy shall be placed in the file. CONDITIONS OF APPROVAL: 1. The applicant shall record a 1041 Site Plan, prior to submission of any building permit applications. All conditions of approval shall be noted on the site plan. The plan shall be modified in the following manner: a. The signature block for the Hearing Officer shall be added. b. An acceptance for recording block for the County Clerk shall be included on the site plan. C. Add a vicinity map to the site plan. d. The 1041 waiver shall state, "Applicant acknowledges that he/she has been informed by Pitkin County of the existence of 1041 environmental hazard areas that might affect the property, any improvements, and the use and occupancy thereof." e. The survey shall be amended to accurately depict the 100 year floodplain line. The survey shall be certified by the surveyor. 3 f. The building envelope, as established by staff, shall be depicted on the site plan. The envelope shall be located a minimum of 20 feet from the 100 year floodplain line. 2. Prior to issuance of a septic permit, the applicants shall provide documentation to the Environmental Health Department stating the proposed use of water for the barn, and the location of the well and the quantity/quality of the water, if required. 3. A septic permit shall be obtained from the Environmental Health Department prior to issuance of a building permit. The septic shall be located 50 feet from the 100 year floodplain line. 4. Woodburning devices are prohibited in barns or agricultural buildings. 5. The applicant shall comply with the following landscaping and wildfire defensible space mitigation standards: a. Brush, debris, and non -ornamental vegetation shall be removed within a minimum 10 foot perimeter around the structure. b. Vegetation shall be reduced to break up the vertical and horizontal continuity of the fuels a minimum of a 30 foot perimeter around the structure. C. Spacing between clumps of brush and vegetation within the 30 foot perimeters shall be a minimum of two times the height of the fuel. Maximum diameter of the clumps shall not exceed 10 feet.

The study, which was conducted by a professional water engineer and is based on accepted floodplain studies, concludes that the lowest floor of the proposed structures are at least 1 -foot above the Base Flood Elevation. Based on the study, I am satisfied that the structure will not impact the 100 -year floodplain. I understand that when the planning office inspected the site this year during peak runoff, Snowmass Creek appeared to be at or near the 100 -year flood event as described within the accepted floodplain studies. This year's runoff event in the Roaring Fork River basin has been categorized as a 15- to 20 -year flood event by the Colorado Water Conservation Board (CWCB). However, this categorization applies to the river basin as a whole, and there is a very good possibility that flood waters in localized areas of the river basin could have reached the magnitude of a 100 -year event during a portion of the runoff period. This concludes my comments regarding this application. Because the development is removed from the 100 -year floodplain, no local or federal floodplain permits are required. Please contact me at #5209 if you have any questions. abs J,9�s Y'1—, is . MEMORANDUM TO: Woodrow File FROM: Suzanne Wolff DATE: September 27, 1995 r] ISSUE: The Woodrow Minor 1041 Hazard Review was approved by the Hearing Officer on March 16, 1995 to allow an accessory envelope for a barn and a shed. As a condition of approval, the applicant was required to obtain a letter from Alan Czenkusch of the Colorado Division of Wildlife (DOW) regarding the potential impact of the proposed structures on the adjacent riparian area and the applicant was required to comply with any conditions imposed by the DOW or the U.S. Army Corps of Engineers. In subsequent site visits to the site to resolve these issues, staff became concerned with the proximity of the proposed shed to the floodplain of Snowmass Creek. The applicant was requested to provide a detailed floodplain analysis for review by staff and the Floodplain Administrator. Tom Newland reviewed the analysis provided by Wright Water Engineers, and is satisfied that the shed will not impact the 100 year floodplain. I have reviewed the original approval, and have determined that no changes need to be made to the conditions of approval. Mr. Woodrow has represented that the shed will not have walls on the end which is closest to the creek and the floodplain, as shown on the plan in the file.

Based on our analysis, the location of the ;roposed structures (shed and barn) would be outside the Snowmass Creek 100 -year floodplain. The analysis included review of the following: • Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (panel 080970)068C, effective date June 4, 1987); • FEMA :Flood Insurance Study, Pitkin County, Colorado and Incorporated Areas dated June 4, 1987; • 1988 and 1994 surveys of the property completed by Alpine Survey, Inc.; • Field visit on August 1, 1995; and • Field survey on August 4, 1995 and August 29, 1995. The flood profile presented in the 1987 FEMA Flood Insurance Study for Snowmass Creek identifies the flood elevations for the 10 -year, 50 -year, 100 -year and 500 -year floods. For the 100 -year flood, the flood elevation is approximately 3.5 feet above the thalweg of the creek. A WWE field survey of seven different locations along Snowmass Creek, on the Woodrow property, determined the minimum elevation from stream bed to the top of the bank to be Raymond Woodrow August 30, 1995 Page 2 approximately 4.1 feet. The stream bed elevation surveyed is approximately one to two feet above the thalweg of the stream, which could not be measured due to high streamflows. In the area adjacent to the proposed shed, the top of the bank is more than 6 feet above the stream bed and approximately 8 feet above the thalweg of the stream. The 100 -year floodplain basically follows the northerly/westerly channel bank and does not encroach onto the lower field adjacent to the stream. The proposed locations for the shed and barn are outside the floodplain boundary as shown on the attached Figure 1. The floodplain was plotted based on field analyses and review of the background engineering data supporting the FEMA floodplain delineation.
