GENERAL PROJECT INFORMATION The Applicant proposes to subdivide a 53.94 acre property into 3 residential lots that are approximately 36, 6.5, and 11 acres in size each with direct frontage on Main Elk Creek (CR 245). The property is generally located about 5 miles northwest of the Town of New Castle in the Main Elk Creek drainage. The Applicant proposes to provide individual water wells on each lot which are also intended to be served by ISDS. All three lots have direct frontage onto CR 243. The property can be physically characterized as lying primarily in the valley floor / drainage of Main Elk Creek which runs through the middle of the property. The property is broken into two benches comprised of an upper bench consisting of irrigated pasture lands which is separated by mature stands of cottonwoods to the lower bench also consisting of irrigated pasture lands with a mature and significant riparian buffer along Main Elk Creek of dense cottonwood trees. Structural improvements to the property include a single-family dwelling, garages, barn, and assorted agricultural outbuildings. These are all clustered on proposed Lot 2. The site plan to the right illustrates these improvements in the context of the proposed lot layout. The property is bound generally by fairly steep slopes to the east and west with similar land uses and character to the north and south. The property to the east is BLM and private property on all other sides. II. GENERAL RELATIONSHIP TO THE COMPREHENSIVE PLAN The property is located in an area that has been designated as "outlying residential" and is not located in the area of influence of the Town of New Castle. This allows for an average density of at least 2 acres per dwelling unit. This proposal in terms of use (residential / agricultural) and average density is compatible with the Comprehensive Plan and general character of the area. III. APPLICABLE ZONING REGULATIONS The following is an analysis of the proposed development with the required zoning regulations of the ARRD zone district. 204 TOTALeLUW1[ Twx. MOWN Til TAl. MAME 'OM AREA ION MAIM ArraRif TOM PROPC 2 • • 4 A. Proposed Uses in ARRD Zoning The Applicant proposes single-family residential development on all 3 lots which is a "use by right" in the A/R/RD zone district and is therefore consistent with the underlying zone district. For other uses, the Applicant should consult Section 3.02 of the Zoning Resolution. B. Common Dimensional Requirements in ARRD Zoning 1. Minimum Lot Size of 2 acres: The Applicant proposes the 53.94 -acre property be (\,-, subdivided into three (3) lots that are approximately 36, 6.5, and 11 acres in size which satisfies the minimum lot size in the zoning. 2. Maximum Lot Coverage: Fifteen percent (15%) 3. Minimum Setback: o Front yard: (a) arterial streets: seventy-five (75) feet from street centerline or fifty (50) feet from front lot line, whichever is greater; (b) local streets: fifty (50) feet from street centerline or twenty-five (25) feet from front lot line, whichever is greater; o Rear yard: Twenty-five (25) feet from rear lot line; o Side yard: Ten (10) feet from side lot line, or one-half (1/2) the height of the principal building, whichever is greater. 4. Maximum Height of Buildings: Twenty-five (25) feet IV. APPLICABLE SUBDIVISION REGULATIONS The following section addresses common subdivision components that will need to be addressed as part of any Preliminary Plan and Final Plat submittal to the County. A. Domestic & Irrigation Water An existing well already serves the dwelling on lot 2 and the Applicant proposes to install individual wells on Lots 1 and 3. The water rights for these wells are to be obtained by an augmentation plan that is presently being reviewed by the water court. Physically, the application states that the location of the new wells in the alluvium of Main Elk Creek should prove an ample physical supply. The pending Augmentation Plan is included in the application and does propose 1,500 sq. ft. of irrigation for each new well and 3,000 sq. ft. for the existing well. It appears the property benefits from certain raw water irrigation sources (ditches, springs). This should be detailed at Preliminary Plan noting which entity shall own these rights, etc. Section 4:91 of the Subdivision Regulations requires that a water supply plan, at the same scale as the Preliminary Plan, shall provide the following information in graphic and/or written form: A. In all instances, evidence that a water supply, sufficient in terms of quality, quantity and dependability, shall be available to ensure an adequate supply of water for the proposed subdivision. Such evidence may include, but shall not be limited to: 3 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 subdivision, 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 the final plat; and 5. Evidence concerning the potability of the proposed water supply for the subdivision. D. If individual water systems shall be provided by lot owners, a report indicating the availability of ample potable ground water at reasonable depths throughout the subdivision and the expected quality and long-term yield of such wells, with the written report by a registered professional engineer licensed by the State of Colorado, qualified to perform such work; and E. 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 applicant, even if the applicant is not the actual supplier of water. Section 9:51 requires an adequate potable and irrigation water supply shall be available to all lots within a subdivision, taking into consideration peak demands to service total development population, irrigation uses, and adequate fire protection requirements in accordance with recognized and customary engineering standards. 9:52 Individual wells may be used as the water supply, provided the applicant has submitted the required documentation to the appropriate water court, and the Colorado Division of Water Resources will approve well drilling permits for all lots within the development. B. Waste Disposal The application states that wastewater generated from the two new residential uses on Lots 1 and 3 are to be accommodated by ISDS. Lot 2 presently has an ISDS in place serving the existing dwelling. It appears the soils prevalent on the property are deep and well drained and suitable for ISDS. All local and State regulations shall be followed regarding any need for an engineered system. C. Roads / Access All three lots have significant frontage along CR 243. The Applicant proposes no new internal roads. Presently, there are two access points from CR 243 that serve the property. The southerly access point off of CR 243 is a shared 30 -foot driveway / easement that straddles the property line between the subject property and the neighbor to the south. This is a recorded easement as shown on the plat that shows access to Lot 1. 4 • • The second access point is a long established driveway serving the existing dwelling on Lot 2. The Applicant proposes a third (and new) access point north of the main existing driveway to serve as the access point to Lot 3. This access point appears to have good site distance in the north / south direction but would require a driveway permit from the Road Bridge Department. Staff suggests this access point be more aligned with the fence on the northwest corner of the lots so as not to split the pasture land in two awkward pieces leaving it intact. D. Fire Protection The property is located in the Burning Mountain Fire Protection District. As such the Applicant shall be required to address the following sections of the subdivision regulations in the Preliminary Plan application. 9:71 Subdivision fire protection plans shall be reviewed by the appropriate fire protection district to ensure that all lots have primary and secondary access points to escape fire entrapment. 9:73 Where there is no central water system available, a centrally located fire protection water tank shall be designed to meet the fire protection needs of the subdivision and be" approved by the appropriate fire protection district. 9:74 Water used for fire protection purposes does not have to be potable water and may be from a source separate from the domestic supply. E. Drainage The property slopes in a relatively gentle manner from the west to east towards Main Elk Creek. Due to the large size and gentle slopes of the property, it does not appear that drainage will be a significant issue during subdivision design. The Applicant will be required to address the following: 4:80 SUPPLEMENTAL INFORMATION: DRAINAGE PLAN A drainage plan, at the same scale as the Preliminary Plan and prepared by an engineer registered in the State of Colorado, shall depict the following information in graphic and/or written form: A. Existing water courses and lakes; B. Limits of tributary areas, where practical; C. Computations of expected tributary flows; and D. Design of drainage facilities to prevent storm waters in excess of historic run-off from entering, damaging or being carried by existing drainage facilities, and to prevent major damage or flooding of residences in a one hundred (100) year storm, showing: 1. Area subject to inundation; and 2. Location and size of proposed culverts, bridges, ditches and channels. 9:41 Drainage easements, channels, culverts and required bridges shall be designed by an engineer registered in the State of Colorado. 5 • 9:42 All drainage facilities shall be designed based on a twenty-five (25) year frequency storm. 9:43 Where new developments create run-off in excess of historic site levels, the use of detention ditches and ponds may be required to retain up to a one hundred (100) year storm. 9:44 All culverts shall be designed such that the exposed ends are protected by encasement in concrete or extended a minimum of three feet (3') beyond the driving surface on each side. Culverts, drainage pipes and bridges shall be designed and constructed in accordance with AASHO recommendations for an H-20 live load. F. Floodplain The property is bifurcated by Main Elk Creek. A portion of the creek's floodplain (just outside of New Castle) has been mapped by the Soil Conservation Service in 1986 but the mapping ends several miles south of the property. As such the portion of the creek that runs through the subject property is not located within a mapped floodplain. The County does require that all development be located at least 30 feet from the high water mark on each side of any live stream. Specifically, Section 5.05.03 in the Zoning Resolution of 1978, requires that A setback of 30 feet measured horizontally from and perpendicular to the high water mark on each side of any live stream shall be protected as greenbelt and maintained in conformance with the definition thereof, with the exception of diversion facilities as an accessory to an approved use on the lot. Section 2.02.28: Greenbelt: Land retained in an open or unimproved condition, except for agriculture, for the placement of landscape materials, including trees, shrubs and grasses and structures limited to foot paths, bridges, irrigation structures, erosion protection devices and underground utilities, or improved for park use as defined herein; ownership of such land may be private with an easement or reservation for greenbelt use by deed restriction, or it may be dedicated to the public. Designation of greenbelt does not imply provision for access by the public. This area shall be shown on the preliminary plan and this greenbelt definition shall be included as a plat note on the Final Plat. 6 • • G. Wildlife The Applicant shall be required to address the following at preliminary plan: 4:70(D) Wildlife - Description of wildlife habitation, including big game ranges based on the mapping practices of the Colorado Division of Wildlife. H. Soils / Geology The application provides that the soils in the area include Jerry Loam, Torrifluvents, Torriothents-Rock Outcrop complex, and Ascalon -Pena complex. Predominantly these soils appear to be well drained and suitable for community development. The Applicant shall also address the following section in the Subdivision Regulations for preliminary plan: 4:70 SUPPLEMENTAL INFORMATION: GEOLOGY & SOILS Information on the following characteristics of the area proposed for subdivision shall be shown graphically and/or by reports, whatever is appropriate, for a complete description of existing conditions, and shall include: A. Geology - Description and/or illustration by a registered professional engineer licensed by the State of Colorado of bedrock lithology and the stratigraphy of overlaying unconsolidated materials in sufficient detail to indicate any potential development problems resulting from groundwater, subsidence, instability in road excavations and ills, expansive soils, drainage patterns, structural bearing strength, or the like; I. Vegetation The Applicant shall be required to provide a weed management plan to be approved by the County Vegetation Manager as well as provide a revegetation security prior to final plat to ensure that any required revegetation is established for improvements made in the subdivision. The Applicant shall also address the following section in the Subdivision Regulations: 4:70 SUPPLEMENTAL INFORMATION: GEOLOGY, SOIL, VEGETATION AND WILDLIFE J. Vegetation - Map and description of plant associations following practices of the Soil Conservation Service and including a description of adapted materials and the location of major tree masses. K. Mineral Estate It is unclear if the property' s mineral estate has been severed and is owned or leased to another party. If so, the Applicant shall include a plat note on the final plat stating the following: "The mineral rights associated with this property have been partially or wholly severed and are not fully intact or transferred with the surface estate therefore allowing the potential for natural resource extraction on the property by the mineral estate owner(s) or lessee(s)." L. Easements It appears the only easement that will need to be addressed is the shared driveway between the neighbor to the south and the subject property located on the southerly property line. The terms 7 • • of this easement shall need to be determined and formalized with the Final Plat. There are no other amenities to be shared within the subdivision such as a water system, internal roads, or open space). M. Assessment / Fees The property is located in Traffic Study Area 4 which requires a $104 per average daily trip (ADT) fee be paid to the County in a traffic impact fee. This fee will be figured at the time of final plat. The Applicant could expect to pay an approximate fee of $2,985 of which l/ shall be paid at final plat and included as a component of the Subdivision Improvement Agreement (SIA). The remaining half shall be divided among the lots to be paid at the time building permits are submitted to the County for individual lot development. The development is also located in the RE -2 School District. As such the developer is required to pay the appropriate School Site Acquisition Fee to be paid at final plat and included as a component of the Subdivision Improvement Agreement (SIA). This fee is generally calculated as $200 per residential unit. N. Recommended Plat Notes/ Covenants Please be aware, the County requires the Applicant place the following plat notes be included on the final plat and in protective covenants: 1. Colorado is a "Right -to -Farm" State pursuant to C.R.S. 35-3-101, et seq.
