The site consists of 13.964 acres. Individual wells Individual Sewage Disposal Systems (ISDS) Highway 82 Frontage Road A/R/RD A/R/RD REQUEST: OWNER: LOCATION: SITE DATA: WATER: SEWER: ACCESS: EXISTING ZONING: ADJACENT ZONING: I. II. RELATIONSHIP TO TIIE COMPRETIENSTVE PLAN The subject property is located in the Low Density Residential (10 and greater ac./du) Area on the Garfield County Comprehensive Plan of 1995, Proposed Land Use Districts Map, Study Area I. DESCRIPTION OF TTIE PROPOSAL A. Site Description: The property is a vacant parcel generally located between the Highway 8i Frontage Road and the Roaring Fork River There are no dwellings on the property on the property. There are four (4) ponds on the property that used to J be a part of a private fishing club and a recently filled pond. There are various wetland habitats on the property, related to the ponds and the river. On the southern boundary of the properly is the railroad right-of-way' B. project Description: The applicants have revised the proposal to subdivide a property originally identified as being 22.6 aqes in size and now being 13.964 acres, into two (2) tots (See revised plan riap /application pgt. I l' l4 j. The lots are still proposed to be 6.474 and7.490 acres in size and will have only single family dwellinjs on them. Each of the proposed lots has a building envelope in an area of an existing pond, filled by dredged material from the other ponds. The 4.378 ac. of Roaring Fork Railroad Holding Authority (RFRHA) right-of-way and a tract separatid from the proposed lots by the river and the RFRHA R.O.W. 4-283 acres, ilre no longer a partof the application . It was determined that the RFRHA R.O.W. is a fee simplelitte, resulting in the other piece of property being legally separate already from the rest ofthe property on the north side of the railroad. The residential lots are to be served by water from individual wells. Each of the lots require an engineer designed individual sewage disposal system. Access will be directly off of State Hr"y. 82 Frontage Road, using an existing drive and an additional access easement that crosses over an adjacent property owned by one of the applicants to widen the easement to meet the minimum right-of-way standards for such a road. III. MAJOR ISSUES AI\ID CONCERNS A. Zontng: Each of the lots proposed meets the two (2) acre minimum lot size required for lots in the A/R/RD zone district. The lots do contain very specific building envelopes, located in the area of the filled pond' The application states that there will be two building sites created as a result of this application. The well permits indicate a single family dwelling with an attached caretakers gnit. This is tJchnically a two family dwelling/accessory dwelling. There are no provisions for a "caretaker" unit as a use by right in any zone district. If the applicants intend to build the accessory dwelling and not have to go through a Special Use permit process, the intent needs to be clearly spelled out as apart of this application and appioved specifically as apartof the subdivision approval. At the last meeting, the applicants stated that there was no intent to develop accessory dwellings. B. Comprehensive Plan: Until recently, the recommendations of the Comprehensive planiere only advisory and carried no legal weight as a basis for a decision in a standard subdivision that meets the zoning resolution requirements. In Larimer County vs. Conder, the court determined that the recommendations of the Comprehensive Plan can be used as a basis for approving or denying a subdivision, .r.nifth. zoning resolution supports the application. One of the requirements noted in the decision is that the Subdivision regulations must include language requiring compliance with the Comprehensive Plan. The Garfield County Subdivision regulations in Section 4:33 does require "conformity or compatibility" with the Garfreld County Comprehensive Plan. One of the most significant issues addressed in Conder, that is subject to the most controversy is the applicability of the land use designations in a Comprehensive Plan and the enforcement ofthose provisions over the underlying znnng. The applicant's planner has presented an argument that the designation for the property is more appropriately the medium density residential (6-9 ac.ld.u.), rather than the low d;rity residential (10 ac. /d.u.). He also notes that the Comprehensive Plan is only intended to be advisory in nature by the language contained in the document' Staff acknowledges that the language in the Comprehensive Plan does state that the document ii advisory, but this was based on the legal precedents in existence at that time the Comprehensive Plan was adopted. Conder supercedes those precedents and arguably n.gut.r the language in the plan, particularly given the previously noted SuUaivision Regulation language requiring "conformity or compatibility" with the Comprehensive Plan. Staffcan identiff the location of the property in relationship with the proposed land use districts and can within a reasonable level of accuracy identiff the property as being within the "low density residential" density area. The determination that needs to be made is general conformity with the Comprehensive Plan. All of the lots are over 2.0 acres each, which is consistent with the underlying zoning minimum lot size, but not consistent with the recommended low density residential. The applicant's planner has made a number of statements based upon "minor" constraints, as opposed to the "major" constraints identified as being a basis for the low density residential determination. Staffs response to the statements in the application are as follows: Soil Constraints: Staffwould argue that any time an engineer design is required, due to unusual soil conditions, that the constraints due to soils is significant, therefore a "major" constraint. If we were accept the argument presented, there would only be "minor" constraints, since in theory, any problem can come up with an engineered solution. That, of course, assumes that money is no object. ISDS Constraints: Again, an engineered system is required to deal with the turusual soil conditions, due to the fill. Staffnotes that there may be other issues related to the use of ISDS, that will be discussed in the section of this report dealing with sewage. Stafi feels that any soil requiring an engineered ISDS is a "major" constraint. Floodplain Constraints: Staff concedes that the property is outside of the 100 year floodfhin. This is due to the property being on fill material. The applicant's geoteihnical engineer notes that the bank separating the pond that was filled for the construction is not strong enough to support structures. Staffquestions, whether or not the bank is stable enough to with stand the scouring action of flood waters, should the Roaring Fork river change course during a flood. While there is no identified flood threat, the closeness to the river of the houses, on fill. would indicate a potential for problems. This would arguably, be a "moderate" constraint. Land Use Considerations: Staff concedes that Road conditions and Distance to Urban Uses are minor constraints. In terms of Land Use Compatibility, the residential use is consistent with many of the nearby and adjoining lots. Infrastructure Needs is non-existent in terms of impacts to existing systems. If the systems were available, it would be staffs opinion that a connection to a central sewage disposal system would be appropriate. As a gfoup, these areas are minor to moderate considerations. It is staffs opinion that the physical criteria and the "major" constraints associated with these criteria, a reasonable basis for the "low density residential" designation. Whether or not the applicant's density for the property is based upon the area identified by deed orthe proposed lots, less the RFRHA R.O.W. and hillside, is the issue by which compatibility with the land use map designations. If the property originally included in the application were considered a part of the determination, the proposed subdivision could be found to be compatible with the land use map. This property was22.O acres and the gross density of the project would be one (1) d.u./ I 1.0 acres. Since the RFRHA ownership is considered a fee title, the property is already split and the subdivision is 13.9 acres or an average density of one (1) d.t./6.95 acres each. This would be consistent with the medium density designation proposed by the applicants planner. There is the additional argument that there are lots in the area that are less than 10 acres in size and have submitted a copy of the map for the area that shows only the lots to the east of the project. Staff has developed a GIS map, as discussed at the last meeting, that shows that there is a significant portion of the propertywithin a mile of the project that are in excess of ten (10) acres. (See map pg. /5 ) Many of the lots shown on the map were created in small increments through the exemption process, which required very little analysis of the cumulative impacts of small lots on the floodplain and ground water through the use of ISDS. In addition to the Land Use Districts Map designations, the Comprehensive Plan contains a number of goals, policies and objectives applicable to the proposed subdivision. The following discussion focuses on the applicable sections ofthe plan: HOUSING Goal - To provide all types of housing that ensures current and future residents equitable housing opporttrnities which are designed to provide safe, efficient 4 residential structures that are compatible with and that protect the natural environment. Staff Comment: The applicant identifies the proposed sites as being unique building sites on which riparian areas are preserved. Staffwould contend that the trnique sites are being placed in a unique location, adjacent to the river, that represent a potential water quallty problems and require expensive engineering solutions to place the houses on the lot. These lots will represent expensive, high income lots. TRANSPORTATION: Obiectives: 3.3 Proposed developments will be evaluated in terms of the ability of County roads to adequately handle the traffic generated by the ProPosal. Staff Comment: Staffagrees that the transportation issues are minor in the case of this proposed subdivision. RECREATION A}[D OPEN SPACE Goal - Garfield County Should provide adequate recreational opportunities for County residents, ensure access to public lands consistent with BLMruSFS policies and preserve existing recreational opportunities and important visual corridors. Objective 5.1 - Encourage the location of active recreational opportunities that are accessible to County residents. Objective 5.4 - Rafting and fishing access will be strongly encouraged during the development review process. Policy 5.3 - If physically possible, subdivision and PUDs will be encouraged to design open space areas to become contiguous with existing and proposed open spaces adjacent to the project. Staff Comment: The proposed development meets the previously noted objectives and policies in terms of the proposed dedication to RFRHA. The recreation opportunities created as a result of the dredging of the ponds is only a benefit to the applicants, since the ponds have always been and will remain, private. OPEN SPACE AND TRAILS Goal - Garfield County shall develop, adopt and implement policies that preserve the C. rural landscape of the Roaring Fork Valley, existing agricultural uses, wildlife habitat and recreational opportunities in a mutually beneficial manner that respects the balance between private property rights and the needs of the community. Staff Comment - The applicants have proposed to dedicate the property south of the railroadto RFRHA. IfPJRHA develops atrailalongthe right-of-way, the dedicated land may provide an altemate access to BLM property and the river's south side. Soils/Topography: Included in the application is a current geology and soils study done prior to the dredging of the old ponds and filling of the "River Pond". All of the report is speculative, based upon a number of assumptions and minimal testing of the site, prior to the actual placement of the fill. The engineers state, "the conclusions and preliminary recommendations submitted in this report are based upon the data obtained from the exploratory borings drilled at the locations indicated on Fig. 1, the assumed type of construction and our experience in the area." The applicant submitted additional statements from the engineer stating that the proposed "pile foundation is feasible". Road/Access: The proposed lots will have a single access point to the Highway 82 frontage road which is an access, shared by two adjacent residences. The applicants propose to improve the common use section of the roadway to two 8'wide driving lanes, consistent with the Semi-primitive road standard required for 3 to 10 dwellings. It is proposed to expand the right-of-way to 40' as required and meet the other requirements for ditches and shoulders. Cross sections were provided as a part of the plans to evaluate these criteria and as required by Section 4.93 of the Subdivision Regulations at the last Planning Commission meeting. Lot2,the westerly lot will be provided a 25' easement across the adjoining property owned by one of the applicants. It is proposed to be a 12' wide, graveled drive. As a driveway, it is not subject to the Cotrnty Subdivision regulation road standards. Water: Enclosed with the application are two approved well permits for "ordinary household use inside one (l) single family dwelling with an attached caretaker apartment and the irrigation of not more than 6,000 sq. ft. (0.14 ac.) Of home gardens and lawns". These well permits were issued based upon Water Allotment contracts approved by the Basalt Water Conservancy District. The applicants had Zancanella and Associates, Inc., review a pump test done by Samuelson Pump Company, on a well on the applicants' property. It is not clear from the letter, whether the tested well is on an adjoining property or is supposed to be one of the two proposed wells. The location description is not consistent with the descriptions noted on the approved well permits. Regardless, the well test indicates D. E. that there is reason to believe there is an adequate physical amotrnt of water available in the area and the approved well permits provide documentation of the legal right to the water. Prior to any Final Plat approval, all of the wells will need to be drilled and the following documentation provided: That a four (4) hour pump test be performed on the well to be used; A well completion report demonstrating the depth of the well, the characteristics of the aquifer and the static water level; The results of the four (a) hotr pump test indicating the pumping rate in gallons per minute and information showing drawdown and recharge; A written opinion of the person conducting the well test that this well should be adequate to supply water to the number of proposed lots; An assumption of an average or no less than 3.5 people per dwelling unit, using 100 gallons of water per person, per day; The water quallty be tested by an approved testing laboratory and meet State guidelines conceming bacteria , nitrates, dissolved solids and is deemed fit for human consumption. Sewer: The applicants are proposing to use Individual Sewage Disposal Systems (ISDS) for both of the lots. Percolation tests were performed by the applicant's geotechnical engineer, after the pond was filled. The percolation tests indicated that conventional ISDS are feasible, in the "upper, drier fill soils with proper design." The applicant's engineer reviewed the information and recofirmended that the leach field be of the "mounded type", due to the potential for high ground water and the need to place the field on fill material. While the applicant's engineers note the need to meet setback requirements, staffquestions whether or not the building envelopes are going to be large enough to accommodate the residential structures, septic tanks and leach fields. A leach field has to be 50 ft. from any water course or pond, 100 ft from any well. There is an additional 8 ft. of setback for each 100 gallons of design flow over 1000 gallons. The applicants submitted a site plan, that shows a proposed house and septic system layout meeting thgse requirements at the last Planning Commission meeting. (See enclosed pg. I b I A 1000 gallon septic tank allows for a maximum of three (3) bedrooms. If this limit is acceptable, it should be noted on a plat. Fire Protection: The applicants propose to use the remaining ponds for fire protection purposes. The Carbondale & Rural Fire Protection District agrees that this will be adequate. Floodplain: Staff acknowledges that the proposed lots are above the identified floodplain, but they are placed on an artificial fill. The geologic report is based upon 1) 2) 3) 4) s) 6) F. G. H. I. borings into the fill embankments surrounding the old pond. The applicant's engineer notes that the proposed sites sit above the 100 year flood elevation and does ,roi f".l that there is any real threat from flooding. Staffhas seen a sudden change in the course of the river during high waters in the early 1980's, that resulted in a direct threat to a residence due to scouring. The floodway is identified as being adjacent to the embankments, but only four (a) ft. below the top of the embankment. t6is is an example of the river being a nice setting most of the year, but no real concern about the potential hydraulic action that occws during a flood event' The following issues subdivision: will need to be included in the covenants of the proposed 1. One (l) dog will be allowed for each residential unit within a subdivision and the dog shall be required to be confined within the owners property boundaries. The requirement will be included in the protective covenants for the subdivision with enforcement provisions allowing for the removal of a dog from the area as a final remedy in worst cases. 2. No open hearth solid-fuel fireplaces will be allowed anywhere within an exemption. One (l) new solid-fuel buming stove as defied by C.R.S. 25-7- 401, et. seq., and the regulations promulgated thereunder, will be allowed in any dwelling unit. All dwelling units witl be allowed an unrestricted number of natural gas buming stoves and appliances. 3. Each subdivision shall have covenants requiring that all exterior lighting be the minimum amount necessary and that all exterior lighting be directed inward, towards the interior of the subdivision, except that provisions may be made to allow for safety lighting that goes beyond the property boundaries. 4. Control of noxious weeds is the responsibility of the property owner. 5. All exterior lighting be the minimum amount necessary and that all exterior lighting be directed inward, towards the interior of the subdivision, except that provisions may be made to allow for safety lighting that goes beyond the property borxrdaries. 6. All residential construction will be consistent with the Colorado State Forest Service (CSFS) recommendations for construction of homes contained in the CSFS publications "Wildfue Protection in the Wildland/Urban Interface" and "Model Regulations for Protecting People and Homes in Subdivisions and Developments. IV. 7. Garfield County has adopted a "Right to Farm" provision in the Garfield County ZonngResolution in Section 1.08, which states among other things, that "residents and visitors must be prepared to accept the activities, sights, sounds and smells of Garfield County's agricultural operations as a normal and necessary aspect of living in a County with a strong rural character and a healthy ranching sector. J. Other Comments: 1. Colorado Geologic Surve)r: Based on the documented geologic constraints, the Geologic Survey agrees with the I{P Geotech report and recommendations. After a conversation with stafl the CGS still agrees that geotechnical investigations of the actual fills will need to have frrther investigation, ifthey are to used for structural support. They do not see any geologic constraints that would prevent development, if the proper geotechnical design is done. (See letter pgs. t?+ [g 1' 3. Division of Wildlife: Enclosed are letters noting that there will be a loss of critical habitat as a result ofthe dredging and filling activities. A number of recommendations were made regarding silt fencing, dog restrictions and notification of property owners ofthg potential problems that can be created by indigenous wildlife. (See pgs. /?dl ; 4. Roaring Fork School District RE-l: The enclosed letter requests a school site acquisition fee be collected as a part of the subdivision approval consistent with a formula adopted by the District. (See pgr"Irs) 5. Colorado Department of Health and Environment: The Department provided no written comment, which is technically approval of the proposed method of sewage disposal. 6. Colorado Division of Water Resources: Based on the information provided to the Division, stated that there will be a legal and adequate water supply available for the subdivision, provided th4t the water allotment contract is properly maintained.. (See letter pgs. ? C t SUGGESTED FII\DINGS A. That the proper publication, public notice and posting were provided as required by law for the hearing before the Cotlrty Planning Commission; and C. D. That the hearing before the County Planning Commission was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that hearing; and That the proposed subdivision of land is not in general compliance with the recommendations set forth in the Comprehensive Plan for the unincorporated area ofthe County; and That the proposed subdivision of land conforms to the Garfield County Zonrng Resolution; and That all data, surveys, analysis, studies, plans and designs as are required by the State of Colorado, and Garfield County, have been submitted and, in addition, have been found to meet all requirements of the Garfield County Subdivision Regulations. RECOMMENDATION That the Planning Commission can recoflrmend DENIAL of the proposed subdivision based on noncompliance with proposed land use districts map designation of a minimum density of one aweiting/tO ac. of land. The applicants argue that there are a number of lots in the area that are less than 10 acres in size and that the proposed subdivision is compatible with that lot size. Staffconcedes that there are lots less than l0 acres in size near the applicants, but all of these lots were created prior to the adoption of the Proposed Land Use Districts Map by the Planning Commission in 1995. Additionally, all of these lots were created via the exemption process, which requires a limited amount of information and analysis to gain approval. thl Comprehensive Plan was developed, based upon a better analysis of the constraints in the area and reflects the current intent of the Planning Commission regarding land use densities along the Roaring Fork River.

The revised boundary of the subdivision will invalidate the original public notice. The Applicant is proceeding to republish a notice for a public nelring on July 8th, the date'to which our original application was continued to by the Fdnniig and 2oning Commission. The publication deadline for the July 8th meeting is Tuesda!, June Zg. The revised plat drawings will be provide to the County by Tuesday, June 23th. The revised legal description excludes the land south of the railroad right-of'way. Don DeFord raised a question as to the appropriateness of including this tract in the subdivision since ihe raitroad has drbady created this southerly tract as a separate parcel from the rest of the property. The most expeditious solution was to follow Don's iecor*"ndation and to republish'the public notice based on the new boundary description and the description of the proposed access easement' The revised subdivision now contains two single family residential lots' The lots are 6.474and 7.4g0 acres in size. This is a gross density of one dwelling per 6.98 acres. No accessory dwelling units are requesteA. Rlttrough it has no technical relationship to the revised subdivisio-n, the Applicant still proposes to dedicate the land south of the railroad to the rail authoritY. The proposed lots are not inconsistent with existing lots in the area. Attached is a copy of a poriion of the County Accessor's map that reflects the general.size of lots in the area relative to the two proposea lots. When all factors are considered, we believe that the proposed subdivision is appropriate and consistent with the character of developrnent in the sunounding area, even though it may not be in strict compliance with all elements of the Comprehensive Plan. - /)_- lf you have questions or require any additional information please contact myself or Luther (Lou) Moore.

A site inspection was conducted on May 20,1998. The site lies on river alluvium near Highway 82. Proposed residences are planned where ponds have been backfilled. This office has reviewed the Preliminary Subsoils Study by HP Geotech dated March 31, 1998 and we generally concur with its content. We agree that the backfill and embankment materials are unsuitable for residential structure support. ISDS design must also be engineered on a site specific basis. Shallow ground water may be a concem so engineered, non-conventional, systems will be required. Provided the deep foundation and mounded type septic systems recommendations are complied with for this site, this office finds no other major geologic hazards that would preclude development. As stated in the Subsoils study there is low risk of potential bedrock dissolution and subsidence of the Eagle Valley Evaporite underlying the river gravel. Potential lot buyers or builders should be made aware of this risk. If you have any questions please contact this office at (303) 894-2167. Sincerely, M/ Jonathanl.

A variety of wildlife species utilize the area including small mammals (beaver, muskrats, raccoon, skunk, coyotesretc. ), song birds, and waterfowl. The proposed development area is most valuable to waterfowl. fne siftation of the 2 easterly ponds have, in fact, created better wetlands for waterfowl r^rith the variety of wetland vegetation present. The property across the river on the steep hitlside contains winter range for mule deer and elk. It is adjacent to other parts of the Crown which contain critical winter range for deer and eIk. The current proposal designates this as open space which hrill continue to benefit wildlife. fmpacts to wildlife wiII result from the dredging of the 2 easterly ponds and fill of an existing pond. There wiII be direct loss of valuable wetland habitat. Deepening the 2 easterly ponds to create a better fishery does not mitigate the Ioss of wetland and riparian vegetation. If the proposal is approved as designed, the following recommendations will help to minimize witdlife impacts: 1-. It would be best if there r^ras a no net loss of wetlands. Creating new wetlands on site may not be possible due to property line constraints. Investigate the possibility of creating wetlands off site to replace those lost 2. Maintain wetlands and riparian vegetation south of the proposed buitding envelopes and along the river as well as those along the westerly border and access route. 3. Install silt fencing along the south edge of the development on the bench above the river and associated wetlands (above the current chain link fence). This fencing should be in place before any surface disturbance, maintained throughout the development period, and removed only after construction is finished and any disturbed soils/sites revegetated.

Division 5, W. District 38 Dear Mr. Bean: We have reviewed the additional information submitted in regard to the above referenced subdivision proposal. The modified proposat is to subdivide a parcel of approximately 22.6 acres inlo 2 residential lots of 6.4 and7.5 acres, with one single family dwelling on each of the these two lots. The remaining 8.7 acres is designated open space/common arca and railroad right-of-way. There are several existing ponds on the parcel. The applicant proposed to provide water through individual on lot wells pursuant to a contract with the Basalt Water Conservancy District (the District). A copy of the contract was provided. Sewage disposal will be through individual septic systems. Well permit nos. 49280-F and 492E1-F were issued by this office on December 1 , 1997, pursuant to contracts with the District. The wells are each limited to ordinary household purposes inside one single family dwelling with an attached caretaker apartment and the irrigation of not more than 6.000 square feet of home garden and lawns. However, we have not received a WellCompletion Repoft, Pump lnstallation Report, or Statement of Beneficial Use for these wells. lf these documents are not receive prior to December 1 , 1998, the well permits will expiie and be of no effect. The April 21, 1998 report by Zancanella and Associates, lnc., indicates that the Englund and Moore well produced an average of 7.5 gallons per minute over a four hour period on April 8, 1998. lf the additional wells have similar production rates the water supply should be physically adequate. Based on the above, it is our opinion, pursuant to Section 30-28-136(1Xh)(l), that the proposed water supply will not cause material injury to decreed water rights, so long as the applicant maintains valid well permits, and is physically adequate. lf you or the applicant has any questions concerning this matter, please contact Craig Lis of this office for assistance.
