Approximately 90 acres Shared well Individual Sewage Disposal Systems (rsDS) County Road 127 (Three Mile Road) Via an easement R/L/SD ADJACENT ZONING: I RELATIONSHIP TO TIIE COMPREIIENSIVE PLAN The subject tract is located in the Medium Density Residential (6 to less than IO acres per dwelling unit) pioposed Land Use District Map, Study Areas l-3, as designated in the Garfield County Comprehensive Plan of 2000. DESCRIPTION OF THE PROPOSAL A. Site Description. The subjecttractis approximately 90 acres in size, located "dl"*"t t"the City of GlLnwood Springs, west of the CardiffBridge area. There is an existing dwelling located on a knoll that is reached from an easement that North; East. City of Glenwood Springs South: R/L/SD West: OiS II o intersects County Road 127. Slope across the tract is steep, generally in excess of 50%o, hower.., ih. area around the existing residence has slopes between 2lo/o and 36%. B. proposal: The applicant proposes to subdivide the tract, by exemption, into three (3) ffiels with lot-sizes of the new parcels of approximately 2.6l9.and 3.09 acres each, with a remaining parcel of 86.07 acres. See sketch map in the application. Each parcel would share a domestic well for water and utilize individual sewage disposal systems for sewage treatment. Access to the property is vial an access easement off of Three Mile Road (CR 127). C. History: The applicant submitted an application in late 1997 and reviewed in February of 1998. The Board conditionally approved the request, subject to the applicant meeting various conditions of approval The approval expired due to the applicant not submitiing the information and documents necessary to meet the conditional approval given by the Board. MAIOR ISSUES AND CONCERNS A. Subdivision Regulations-. Section 8'.52 (A) of the Garfield County Subdivision n.grlutiors states that "No more than a total of four (4) lots, parcels, interests or awahng units will be created from any parcel, as that parcel was described in the recordi of the Garfiekl County Clerk and Recorder's Office on January l, 1973. In order to qualtfufor exemption, the parcel as it existed on January l, 1973, must have been larfer than 35 acres in size at that time and not Part of a recorded subdivision; however, any parcel to be divided by exemption that is split by a public right-of-way (Stare o, i"iurol higlnuay, County road or railroad), preventing ioint use of the proposed tracts, and the division occurs along the public right-of-way, such parcels -theieby created may, in the discretion of the Board, not be considered to have been creatid by exemption with regard to the four (4) lot, parcel, interest or &ttelling unit limlafion otherwise applicabie. For the purposes of definition, all tracts of land j5 acres or greater in size, created after January l, lg 73, will count as parcels of land created by exemption since Jonuary l, 19 73; The applicant's ownership originally consisted of three parcels, all of which existed prior to January l, 1973. As a result of making some boundary line adjustments in ih"r. pur..|s, t-he application is now being made on the largest remaining tract. Staff had pieviously reseiiched the Assessor's records and determined that all of the original pur""l, re in iheir original configurations. Based on this analysis, this petition would comply with Section 8.52 (A) of the Subdivision Regulations. B Zoning.. The entire tract is zoned R/L/SD, which mandates lot sizes of at least 20,000 ,qu*. f..t. However, due to the utilization of well water and individual sewage disposal systems, the minimum lot size is required to be two (2.0) acres. All proposed lots would comply with this minimum, lot size requirement' a M C o o Slope: Section 5.04.02(2) of the Garfield County Zoning Resolution, requires that all l,16;least two (2) acres in size, must have at least one (1) contiguous acre of land, less than 4Oo/o in slope. Based on staffs review of a topographic map submitted as a part of the 1998 applicition, it is apparent that a majority of the property has slopes over 40o/o. Building en "lop"s smaller than one (1) acre in size may be approved by the Board, providj the certain information is submitted and reviewed by the Board as a part of the Lxemption. No such documentation has been submitted for review, therefore it will be n"".rrury for the applicant to demonstrate that there is at least one (1) acre of land less than 4Oi/o on each lot. This information was a condition of approval attached to the previous approval given by the Board. Staff suggests that the Board attach this requirement as a condition of approval. Water Supply.- The existing dwelling is served by a permitted, domestic-use well and the -propor"b- lots would be served by an exempt, domestic well. The applicant has iubmitted a copy of well permit No. 206246, approved November 24,7997 and with an expiration date,iwo years later. The permit was extended to November 24,2000 The *.ll *u, drilled in April of 2000, to a depth of 440 ft. and a production rate of l5 gpm. A subsequent four hbur pump test confirmed the 15 gpm pump rate, with a water level of 324 ft. and a drawdow, oi tO ft.. It has the been the County's policy to require an applicant to provide the following information as a part of any approval of an exemption: 1) That a four hour pump test be performed on the well to be used; 2) A well completion r.port demonstrating the depth of the well, the characteristics of the aquifer and the static water level; 3) The results of the four hour pump test indicating the pumping rate in gallons per minute and information showing down draw and recharge; 4) A written opinion of the person conducting the well test that this well should be adequate to supply to the number of proposed lots; 5) An assumption olan average or no less than 3.5 people per dwelling unit, using 100 gallons of water Per Person, Per daY; 6) ihe water quality be tested by an approved laboratory and meet State guidelines concerning bacteria, nitrates and suspended solids; 7) A water iharing agreement will be filed with the exemption plat that defines the right of the property owners to water from the well. The applicant has addressed numbers 1-5. It will be necessary to address numbers 6 and 7, alongwith the surveying of the well location showing a 10 ft. square around the well and a 10 ft. wide well access and maintenance easement' Soils/Sewer: The method of wastewater treatment is proposed to be individual sewage airp*uf rystems (ISDS). According to the Soil Conservation Service, the soils are considered to be Toriiorthents-Rock outcrop complex, which are not specifrcally evaluated for constraints to building site development and sanitary facilities, but the report does state that community development is limited by the rock outcrop, steep slop"s and stoniness. However, the Service states that constraints may be mitigated D E oo through appropriate design and construction. Staff recommends that, if approved, all building foundations and ISD systems be engineered. Not noted in the soils information, but a known circumstance for the area, is the rock fall hazard due to the steep and stoney slopes. If all of the construction is done in areas with gentler slopes, there may not be a hazard to the new structure from rolling rocks, but an=y construction done wiih uphill slopes may need to have the construction mitigated to deai with the rock fall hazard. Additionally, any construction done with steep slopes below the building area will need to take extra precaution to insure that structures below the construction site are not subjected to falling rocks. A plat note stating that falling rocks are a hazard in this area and that any construction of new buildings needs to mitigate the hazard by protecting the new structure from uphill rock fall and insure that down hill structures wilf not be subjected to any rock fall due to construction activities. Access: Access to the property is via an easement, apparently 50 feet in width, which lntor..tr County Road 121. The easement appears to be a non-exclusive, assignable easement of indeterminate width, perhaps as wide as 50 feet' Fire Protection: The Glenwood Springs Department of Emergency Services has provided u l.tt", noting the property is aciessed via a nonconforming access that is not consistent with SectiongOZ of the t-qq+ Uniform Fire Code ([IFC). To meet the UFC standards, the roadway will have to be upgraded or all new buildings will have to be completely protected by an approved automatic sprinkler syst€m. _ To meet this requirement, the water supply system has to be capable of delivering the fire flow required per UFC Section 903. In addition to this requirement staffsuggests the inclusion of the standard plat note addressing wildfire protection, due to the steep slopes and heavy vegetation on the property.. Easements- All required easements for access, utilities, water supply, etc', will be required to be shown on an exemption plat. IV.
