MEMORANDUM To: Ellen Sassano, Community Development Dept. From: Mary Engelmann, Environmental Health Officer Through: Lee Cassin, Assistant Environmental Health Director Date: July 15, 1996 Re: Jaffee/Prince Creek 1041 Hazard Review - ADDENDUM Parcel ID H 2463-241-00-004 The Aspen/Pitkin Environmental Health Department has reviewed the details of the Jaffee/Prince Creek Hazard Review application under the authority of the Pitkin County Code Title II Land Use Code and has the following comments. According to the applicant, there is an existing engineered design sewage disposal system on the property. There are no records of this system in our files. Given the information that was submitted for this review, it is likely that the system was designed for typical barn use only and not for use for a home, which would mean that the system will be required to be enlarged. ADEQUATE PROVISIONS FOR WATER NEEDS- Sections 2-170 and 3-110A "It is the policy of the county to Insure the availability of a water supply of adequate quality, quantity, pressure and dependability for fire protection and support of a proposed land use prior to approval of the use. The county shall require land uses to hook up to existing public systems if service is available.' This Department needs adequate information on the quantity and the quality of water available. This can be done from tests of wells present on-site by a water engineer's or well driller's report. The applicant must ensure that the water quality is acceptable by having it tested by a lab such as the Snowmass Water and Sanitation District or Aspen Consolidated Sanitation District. Before a septic permit can be issued, the well must be drilled to assure that setback requirements from the well to the sewage disposal system can be maintained. Pitkin County Land Use Code requires that the well site be within the building envelope. Since a site plan was not included in this packet, it is unknown whether the well will fit within the building envelope. It is recommended that low water landscaping (xeriscaping) be used and that the timing of any sprinkler systems be decreased for low water plants. The Colorado State University Cooperative Extension office can be contacted for more information on xeriscaping. A condition of approval for this application is the receipt of information documenting that the location of the well(s) meet setback requirements and UQU00 ©OQQO1 ��) can be placed within the building envelope and that quantity/quality of the well water are adequate. Without meeting these requirements a sewage disposal system permit and building permit can not be issued. SEWAGE TREATMENT AND COLLECTIONa Sections 2-180 and 3-110.5: "It is the policy of the County to ensure that adequate sewage treatment facilities are available to serve. existing and new developments. Public and - private sewage disposal systems and connections to such systems shall comply with the sewage disposal guidelines of Pitkin County's Individual Sewage Disposal System Regulation." - - - Lots in the Prince Creek area are served by individual sewage disposal systems. All such systems installed within Pitkin County require septic permits issued by the Environmental Health Department, and must comply with the County's sewage disposal .regulations. As was mentioned earlier, the applicant states that there is an existing engineered sewage disposal system on the property. Unless adequate records are found or supplied to this department, a new sewage disposal system will need to be installed. An application, fee, and all information the information required to install a new sewage disposal system must be supplied. There is a chance that some of the components from the existing system may be able to be used for the new system, but that will have to be determined by this department. it must be possible to design and adequate sewage disposal system before a building permit can be issued. The sewage_ disposal system must be within the building envelope. The Aspen/Pitkin Environmental Health Department will design the system for the applicant as part of the permit fee, if an engineered system is not required. We will do a site visit, advise the applicant about the best location for the system and provide a system design. We will determine if an engineered system is needed based on soil test results. An engineered system is required if any one of the following conditions exists: a percolation rate faster than 5 mpi or slower than 60 mpi; maximum seasonal level of the groundwater table or bedrock less than four feet below the bottom of the proposed absorption system; or a slope in excess of 30%: Prior to initiating any tests at the site, the applicant should contact this office. The applicant will need to adhere to minimum horizontal setback requirements for placement of septic system components. I have included a setback chart that shows all of the required minimum setback distances. The leach field will need to be located a minimum of 100 feet from the applicant's well and from any neighboring wells. Since no site plan was included in the packet submitted, as well as no indication of the proposed building envelope it is impossible to determine if meeting these requirements is possible. The area for the leach field should be located in an area of no traffic, planted with dry land grass, and should not be watered. It is desirable to locate the system downhill from the house so that the system can operate by gravity. The applicant should refer to the Pitkin County Sewage Regulations for detailed information, or call our office to discuss this site. 000002 Unless designed by a registered professional engineer and approved by this Department, no soil absorption system shall be permitted in areas where the ground slope is in excess of thirty percent (30%). If the well permit states that the sewage disposal system must be of the non- evaporative type where the water is returned to the same stream system in which the well is located. This means that a completely lined field, such as an evapo-transpiration bed, is not allowed unless the applicant contacts the Colorado Division of Water Resources and a new well permit is in place or a plan of augmentation is created. A condition of approval for this application is the receipt and approval of the sewage disposal permit by the Environmental health Department before a building permit can be issued and that the sewage disposal system can be located within the building envelope. "It is the policy of the County to preserve and protect its present water resources, recognizing the County's semi -arid character and that significant transmountain and transbasin diversions and the vested rights of senior appropriators in the basin have materially curtailed the availability of an already scarce water resource. To this end it is the policy of the County that no land use be initiated which would adversely affect the quantity, quality, or accessibility of the County's water resources; or which would occur at the expense of established water -dependent agricultural activities; or which would result in increased salinization of water resources, loss of minimum stream flows, further destruction of wildlife habitat, or major expenditures to reacquire or redistribute major water resources. It is also the polity of the County to maintain a natural vegetative buffer along its surface waters such that the surface and groundwaters of the area are not encroached upon by land uses or other human activities which could cause deterioration of water quality or impair the natural treatment processes provided by meadows and wetlands." The Environmental Health Department is charged with preserving and protecting the quality of Pitkin County's water resources. Since a large percentage of the population is dependent upon water from wells, elimination of groundwater pollution, and protection of aquifers and their drainage areas are of utmost importance. A condition of approval for this application is: None. "Only that development is permitted which will not contribute significantly to degradation of air quality. This project is not expected to contribute significantly to degradation of air quality in Pitkin County. A condition of approval should be: None. The applicant must file a fireplace/woodstove permit with the Environmental Health Department before the building permit will be issued. e The less densely populated parts of the county like the Prince Creek area may have two devices per building: a maximum of one wood burning fireplace and a second device which can be either a gas log fireplace or a certified woodstove. In addition, unlimited numbers of decorative gas appliances are allowed. Coal may not be burned in any device. No wood burning device may be installed in barns or agricultural buildings. A condition of approval for this application is the receipt and approval of the fireplace/woodstove permit by the Environmental Health Department before the building permit can be. issued. CONFORMANCE. WITH OTHER ENVIRONMENTAL HEALTH LAWS: Section 2 -70- -It is the policy of the County to ensure that no use or development of land is permitted which isin violation ofthelaws of the County, the State of Colorado, or the united States of America." - This Department is not aware of any issues of concern regarding other. environ mental health laws. _ `i � � ..� 000005 0 P� � \ � 0000 #w K o ,§ ' E2 E2 g n a Em; @ @ )jk }� )2« 6)/ a . {\7 2!! f )i /\ ! f kI ;. §E § @ §E S § e , RSR R { ;E , £ ./\k/!

There is an xisting barn on the property that never had to go through a 1041 hazard review -s' e it was used for agriculture. The applicant would like to convert the barn to a year-r0 nd permanent home. According to the applicant, there is an existing engi designed sewage disposal system on the property, which the applicant would like to rhove to accommodate a 3 -car garage.here are no records of this system in our files,, o it is unknown what the size of the sys em is, what type of system has been instal ed or the location of the system. The reason that an engineered design was gr d is also unknown.
