M., Garfield County Silt Mesa area between Silt and Rifle on County Road 259 (Jewel Lane) Shared Well ISDS CR 259 (Jewel Lane) / Pump Canal Road A/R/RD A/R/RD A. I. PROJECT INFORMATION Site Description The subject property contains approximately 14.43 acres and is located in the Silt Mesa area on County Road 59 (Jewel Lane) approximately one mile north of the intersection with CR 233 between Silt and Rifle. The property has been historically used as irrigated pasture served by existing ditches. The topography is relatively flat with minimal vegetation other than cultivated grasses. Development Proposal The owners of the property propose to subdivide the 14.43 acre property into two lots: Lot 1 having 6.337 acres and Lot 2 having 8.096 acres. II. STAFF COMMENTS A. Comprehensive Plan The property is located in Study Area 2 just outside of the 2-mile sphere of influence for both Silt and Rifle. According to the Septic System Constraints map in the Comprehensive Plan, the property is located in a "High Water Table" area which represents septic system constraints. Regarding density, this Study Area does not prescribe residential densities as in I B o o Study Area 1; therefore, densities are regulated by the minimum lot area of the underlying zoning of 2 acres per dwelling unit in the A/R/RD zone district. B. Zonine The property is located in the Agriculture / Residential/ Rural Density (A/R/RD) zone district which provides that residential dwelling units are a use by right. The proposed lots comply with the minimum lots size. In addition, the applicants propose "building sites" on each lot that also comply with setback requirements. The applicant must be aware of the general dimensional standards requirements as outlined in Section 3.02.01 of the zoning resolution which includes height limits, lot coverage, setback regulations, etc. C. Subdivision The Applicant should be aware of the requirements outlined in Section 4:00 of the Zoning Resolution for Preliminary Plan. It should be noted, Garfield County does not have a "minor subdivision" process. All divisions of land, large or small, are required to respond to the same standards as well as proceed through the same process. This is of particular importance regarding shared wells and access. a. Soils/Geoloey According to the Septic System Constraints map in the Comprehensive Plan, the property is located in a "High Water Table" area which represents septic system constraints. The Applicant provided a "Soils and Foundation Investigation" prepared by CTL / Thompson, INC ("CTL"), fs1 this subdivision. The purpose of the investigation was to evaluate the subsurface conditions at the site and to provide foundation recommendations for the proposed buildings. The conclusions provided by CTL include the following: 1) Ground water was found at 3 feet at the time of drilling the borings. As a result, CTL recornmends no excavation below three feet. 2) Residential structures should be constructed on building pads elevated above the adjacent ground. The top of the building pad should be at least three feet above the existing ground surface. 3) Residences can be founded on footings placed on "stabilized" sandy clays clayey sands. 4) CTL judges potential differential movement of slabs-on-grades supported by densely compacted structural fillwill be low. 5) Surface drainage should be designed to provide for rapid removal of surface water away from the residences. b. Road"/Access The property is bordered by County Road 259 alorgits west property line and "Pump Canal Road" along the northern property line. The applicant proposes to provide access to Lot 1 via CR 259 and access to Lot 2 via "Pump Canal Road." Staff is unclear as to the status of Pump Canal Road and questions the practical ability to pull access from this roadway as it is not a public county right-of-way. Further, the Applicant has not provided any substantive detail as to its legal status. 1t 2 o c. Fire Protection The property is located in the fufle Fire Protection District. The application did not contain any information regarding fire protection. As part of preliminary plan review, Staff will refer the application to the Rifle Fire Protection District for their comments which will be incorporated into the Staff review. d. Water The Applicant proposes to provide potable water to both lots from one shared well which has been approved by the Division of Water Resources pursuant to well permit number 057695-F. The terms on the permit allow for the provision of water for 2 (two) single- family residences, irrigation of not more than 24,000 square feet of home gardens and 1awns, and the watering of up to 10 non-corrunercial domestic animals. The well is to be located on Lot 2 and shared with Lot 1. In addition, the last condition on the well permit requires that a totalizing flow meter be installed on the well and maintained in good working order. As in the proposed subdivision, any well that is to serve more than one property (i.e. shared well) is considered by Garfield County to be defined as a central water supply system. To this end, the Applicant is required to respond to Sections 4:9I,9:53-9:55 of the Subdivision Regulations which require an Applicant to identifu how this system is to be designed by a Colorado registered engineer and provide details of the shared system to be reviewed during the preliminary plan review process. Lastly, the applicant will be required to submit and re0ord a "Well Sharing Agreement" which discusses the specific responsibilities of each individual owner using the well. It also discusses the "Well Easement" which is to be shown on the final plat. Examples of this type of agreement can be obtained from the Building and Planning Department upon request. In particular, the following requirements shall be addressed in the subdivision regulations: Section 4:91 requires the applicant to propose a water supply plan, at the same scale as the Preliminary Plan, whtch provides thefollowing information in graphic and/or writtenform: A. In all instairces, evidence that a water supply, sfficient in terms o-f quality, quantitt and dependabilit.v, shall be available to ensure an adequate supply of water for the proposed subdivision. Such evidence may include, but shall not be limited to: 1. Evidence of ownership or right of acquisition or sue of existing and proposed water rights; 2. Historic use and estimated yield of claimed water rights; 3. Amenability of existing right to change in use; 4. Evidence that public or private water owners can and will supply water to the proposed subdivtsion, including the amount of water available for use within the subdivision by such providers, the feasibility of extending service to the area, proof of the legal dependability of the proposed water supply and the representation that all necessary water rights have been obtained or will be obtained or adjudicated, prior to submission of thefinal plat; and J o B oo5. Evidence concerning the potability of the proposed water supply forthe subdivision. If a central suppbt and distribution s:tstem is to be provided, a general description of the system, as designed by a Colorado registered engiieer. In addition: 1. Nature of the legal entity which will own and operate the water system; and 2. Proposed method offinancing the water system.If individual water systems shall be provtded by lot owners, a report indicating the availabtlity of ample potable ground water at reasonable depths throughout the subdivision ond the expected quality and long-termyield of such wells, with the written report by a registered profeisional engineer licensed by the state of colorado, qualified to pedorm such work; If applicable, a Plan of Augmentation and a plan for subdivision water supplies, as required by law, with the supporting engineering work signed by a Colorado registered engineer, shall be submitted by the appltcant, ,r"ni| the applicant is not the actual supplier ofwater. D. E, e. Waste sposal The applicant proposes to handle wastew ater by Individual Sewage Disposal Systems(ISDS) for each lot. As noted earlier, the site has been identified as having septic system constraints due to a significantly high water table in the area. In particular, ih. applicant is required to demonstrate suitability for this method of waste disposal given the high water table in the area and shall provide adequate responses to Section 4:92 of the subdivision regulation: 4:92 A sanitary sewage disposal plan, at the same scale as the Preliminary plan, shall provide thefollowing information in graphic and/or writtenformi D. If no central sewage treatment worl<s is proposed and individual sewage disposal systems will be utilized, a description of sewage, the dispoial' means, as well as evidence as the result of soil percolation tests and pridrr"" excavations to determine maximum seasonal giound water level and depth to bedrock shall be provided. In addition:1. Indicated by location on the plat;2. Performed and signed by a registered professional engineer licensed by the State of Colorado; 3. Adequate in number and location to meet requirements of the Garfield County Individual Sewage Dtsposal Requirements and the Colorado Department of Public Health, Water Quality Control Commission; and E. If individual sewage disposal systems are to be utilized, a proposed management plan for the operation and maintenance of on-site systemi shall be provided. State and County regulations require that if ground water is encountered within 8 feet of the surface, engineered septic systerns are required to be designed by a professional engineer. 4 O f. Drainage/ Floodplain Issues /Radiation Depending on a site's topography, drainage can be a significant issue for siting residences and access points. CTL reported that the drainage that crosses the site is subject to periodic flash floods and debris / mud flows. They rate the risk from flash flooding and debris / mud flow as moderate which means that "flash flooding and debris / mud flow on the order of 1 to 2 feet in depth can be expected." They do indicate that appropriately placed contouring / grading can effectively mitigate or channel the flows around and away from the proposed residential sites. This will need to be fully explored as part of an extensive drainage study for on and off site storm water drainage as part of preliminary plan. In addition, as noted above, the property has substantially high ground water close to the surface. CTL recommends minimal excavation (2 to 3 feet) elevated building pads (2 feet) above the 100 year flood elevation. More specifically, the CTL report recommends the following general precautions be observed during construction and maintained at all times after residential structures are completed (see page 9 of the report): 1) Wetting or drying of the open foundation excavation should be avoided; 2) Ground surface should be considerably sloped away from the structures' foundations; 3) Backfill should be moisture conditioned; 4) Use downspouts to carry roof drainage away from structures and foundations; and 5) Careful placement of landscaping to minimize irrigation near the structure where seepage could damage foundations. g. Wildlife No information was provided regarding issues related to the presence of wildlife or potential impacts thereto. This will be an issue that will need to be addressed as part of the preliminary plan review. Staff will refer the application to the Division of Wildlife for comments which will be incorporated into the review. h. Assessment / Fees District. In general, the school district collects an impact fee of $200 per lot. cS Area F As mentioned above, the property is located within the Traffic Study Area 6 which requires $210 per Average Daily Trip (ADT). In this case, the proposed subdivision will produce two residential units that produce 9.57 ADT each based on the ITE Manual (6th Edition). ADT generated from the 2 newly created lots will produce a total of 19.14 ADT. The resulting Traffic Impact Fee is approximately $1,870.50 per unit. Recommended Plat Notes/ Covenants Please be aware, the county requires the Applicant place the following plat notes, at a minimum, on the final plat and in the protective covenants: 5 o o 1. "Colorado is a "Right-to-Farm" State pursuant to C.R.S. 35-3-101, et seq.
