HomeMy WebLinkAbout98- David Jarrett at Allison Phase 1 Minor Subdivision , , , Allison Phase I Minor Subdivision Preliminary Plat BEFORE THE BOZEMAN CITY COMMISSION CITY OF BOZEMAN, MONTANA IN THE MATTER OF THE APPLICATION OF FINDINGS OF FACT DAVID JARRETT FOR PRELIMINARY SUBDIVISION PLA T APPROV AL OF THE ALLISON PHASE I AND ORDER MINOR SUBDIVISION PURSUANT to the Montana Subdivision and Platting Act, Section 76.3.101 through 76-3.614, Montana Codes Annotated, and the Bozeman Area Subdivision Regulations, the Bozeman City Commission reviewed the proposed Preliminary Subdivision Plat for the Allison Phase I Minor Subdivision to further divide a 112.21 acre tract into five lots for residential uses plus a remainder, as submitted by the applicant, together with the required supplementary plans and information, to determine if the information submitted meets the requirements of the Bozeman Area Subdivision Regulations and the Montana Subdivision and Platting Act. The City Commission also considered the recommendation of the Bozeman City-County Planning Board concerning the application. It appeared to the City Commission that all parties and the public wishing to appear and comment before the Bozeman City-County Planning Board were given the opportunity to do so, and therefore being fully advised of all matters having come before it regarding this application, the City Commission makes the following Findings of Fact, as required: FINDINGS OF FACT I. The application for the Allison Phase I Minor Subdivision was made on August 28, 1998. The application will divide a 112.21 acre tract into five lots for residential uses plus a remainder. Lot 2 will be 8,498 square feet in size, Lot 3 will be 7,891 square feet in size, Lot 4 will be 8,844 square feet in size, Lot 5 will be 8,504 square feet, and finally Lot 6 will be 8,280 square feet in size. The remainder tract (Lot 1 on the Preliminary Plat) will be 110.92 acres in SIZe. This application was considered the second minor subdivision from a tract of record (C.O.S. 252) because the Morning Star School site was created in 1990 through Minor Subdivision No. 84. In addition to the creation of the Morning Star School site, Minor Subdivision No. 84 also dedicated 422 feet of right.of-way to extend Arnold Street to the west. Except for Morning Star School, the subject property is currently vacant. II. After finding the application was properly submitted and reviewed under the procedures of the Bozeman Area Subdivision Regulations, a meeting was scheduled before the Findings of Fact and Order Page 1 Allison Phase I Minor Subdivision Preliminary Plat Bozeman City-County Planning Board for Tuesday, October 6, 1998 and before the Bozeman City Commission on Monday, October 19, 1998. Notice of the City Commission agenda, as well as the Planning Board agenda, was published in the Bozeman Daily Chronicle on Sunday, September 20, 1998. III. A public hearing for this application was held before the Bozeman City-County Planning Board at their regular meeting on October 6, 1998. The Staff Report to the Planning Board advised the Board that the Development Review Committee had recommended 29 conditions of approval. The applicant was present and provided a brief overview of the project. Three members of the public were present to comment on the application. The public expressed concern about the ground water and soils analysis data, snow storage, the composition and location of fill on the lots, drainage and the proposed improved drainage pond, nearby wetlands, wildlife, and the safety of children attending Morning Star School. After the public hearing was closed, and the discussion was brought back to the Board, several members of the Board expressed concern about the improved drainage pond, snow storage, impacts on nearby wetlands, the water table, and the fill placed on the site. After finding that the application complied with the required criteria established in Title 76-3-608, M.C.A. for the review of preliminary subdivision plats, the Board, on a vote of 8~1, forwarded the application to the Bozeman City Commission with a recommendation of conditional approval. The Board voted to amend condition #18 of the Staff Report by revising the second sentence of the second paragraph to read as follows: "A Geotechnical Investigation Report shall be prepared for the entire site (future roadways, building lots and drainage pond.area) by a Professional Engineer registered in the State of Montana and shall be submitted to and approved by the City Engineer." The Board also voted to add the following new sentence onto the second paragraph of condition #18: "The report shall also evaluate the off-site impact(s), of the water table upon adjacent properties, caused by this project's impact on the water table." Finally, the Board voted to grant a partial waiver from the environmental assessment requirements. IV. The application was considered by the Bozeman City Commission at their regular meeting on October 19, 1998. Staff provided a brief overview of the project and of the issues related to the project. Staff also summarized a memo from the Planning Office dated October 19, 1998. The memo addressed concerns related to the high water table, wetlands, and noise from de-watering equipment that the Commission had expressed during the City Commission Findings of Fact and Order Page 2 ; Allison Phase I Minor Subdivision Preliminary Plat work session on October 12, 1998. The memo recommended possible new language the Commission could add to the conditions of approval to address these concerns. The developer was present at the City Commission meeting and made himself available for questions from the Commission. The developer distributed to the Commission a letter from the Army Corps Engineers that indicates that the wetlands delineation for the site "is acceptable as mapped on the map provided." Otherwise, the developer was in agreement with the conditions recommended by the Planning Board and by staff. As this subdivision is proposed in an area where a Master Plan has been adopted, and is the second minor subdivision from a tract of record, the subdivision is subject to the primary review criteria listed in Section 76-3-608(3a), MCA, 1995. The Commission weighed the proposed subdivision against the applicable review criteria established by Statute, and found as follows: A. Effects on Agriculture - The further subdivision of the subject property should result in few, if any, negative impacts on agriculture. The viability of the site for agricultural uses is marginal for several reasons. First, the subject property has been annexed to the City of Bozeman, and has had an urban zoning designation, for a considerable amount of time. Second, the site is largely surrounded by urban residential development. B. Effects on Local Services - Because only five new residential lots are being created at this time, the impacts upon local services such as garbage collection and disposal, police and fire protection, library facilities, tree maintenance and animal control should be minimal. A new cul-de-sac will be installed that is approximately 210 feet in length. However, the demand for street maintenance and snow plowing generated by this proposal should be minimal. The Streets and Sanitation Superintendent had no comments regarding this proposal. This proposal will only result in five new water and sewer connections with few impacts. Finally, this development could be expected to generate an average of 8.5 school students. There is a elementary school right across the street from the subject site, and a middle school in close prOXimity. To address the impacts this proposal may have on parks, the developer must sign and file a Waiver of Right to Protest the Creation of a City-wide Park Maintenance District(s). C. Effects on the Natural Environment - The site is characterized by several environmental conditions including wetlands, floodplain, an intermittent stream, fill soil and a high water table. The Bozeman Area Subdivision Regulations do contain a provision regarding land unsuitable for subdivision, which reads as follows: Any land which the appropriate Governing Body has found to be unsuitable for subdivision because of potential hazards such as flooding, land slides, excessive slope, rock falls, snow avalanches, subsidence, high water table, polluted or non-potable water; or because of unreasonable burdens on the general public such as requirements for the excessive expenditure of public funds, environmental degradation, and congestion in the streets, shall not be subdivided for building or residential purposes unless the hazards or excessive public burdens are eliminated or will be overcome by approved design and construction plans. In the unincorporated area, slopes in excess of 25 percent shall be presumed un-buildable unless otherwise provided by the developer. In response to this provision, a copy of the Preliminary Plat was forwarded to the Natural Resources Conservation Service (NRCS) and Fish, Wildlife and Parks (FWP) for their review Findings of Fact and Order Page 3 . . Allison Phase I Minor Subdivision Preliminary Plat and approval. The developer has already retained a wetlands consultant to delineate the wetlands on the site. Proposed Lots 2 through 6 will not encroach into the delineated wetlands at all; the delineated wetlands will be contained on the remainder. One of the conditions requires that the developer provide the Planning Office with copies of any Section 404 permits required, or with written verification from the Army Corps of Engineers that a 404 permit is not required, prior to commencement of work on the site. An official floodplain/floodway delineation study has been performed on the floodplain on the subject property, and the floodplain is shown on the FEMA floodplain maps for the City of Bozeman. The Preliminary Plat shows this delineated floodplain, and proposed Lots 2 through 6 do not encroach into the floodplain; the floodplain is contained on the remainder. To address the floodplain issues, the following condition has been imposed: The full extent of the floodplain on the subject property shall be surveyed, and shown on the plans and specifications for infrastructure improvements. If any part of proposed Lots 2 through 6 will lie within the 100-year floodplain, the Final Plat shall contain a note that appropriate floodplain development permits must be obtained from the City Engineers Office prior to construction of any new structures. There is an intermittent stream that crosses the subject property from the south towards the north. The stream is located in the same area as the wetlands and floodplain. Per the Subdivision Regulations, a thirty-five (35) foot watercourse setback must be provided along the stream. According to high water table maps, based on information from the NRCS, the water table on the subject site is 1 ~ to 3 feet below the surface. Therefore, following condition has been imposed: "Due to the extremely high groundwater table in the area, basements are not recommended. If basements are proposed, only daylight basements may be constructed after consulting a professional engineer." If the groundwater table is found to be of an average depth for the area, the final plat shall contain a note with the following language: "Due to relatively high groundwater table within the area of the subdivision, it is not recommended that full basements be constructed without first consulting a professional engineer. " The site has been extensively filled over time which may have resulted in unstable soils that are unsuitable for development. Therefore, the DRC recommends a condition requiring a compaction report if the site contains fill in excess of twelve (12) inches. The compaction report must be prepared by a Professional Engineer who is registered in the State of Montana. The report must satisfy Building Code and Building Department requirements, and must be submitted to the Chief Building Official for review and approval prior to the issuance of any building permits for this subdivision. If construction activities related to the project result in the disturbance of more than five (5) acres of natural ground, an erosion/sediment control plan may be required. The Montana Department of Environmental Quality, Water Quality Bureau, shall be contacted by the applicant to determine if a Storm Water Discharge Permit is necessary. If required by the DEQ, an erosion/sediment control plan shall be prepared for disturbed areas of five (5) acres or less if the point of discharge is less then 100 feet from State Waters. Finally, The Montana Department of Fish, Wildlife and Parks, the Natural Resources Conservation Service, the Montana Department of Health and Environmental Sciences, and the Army Corps of Engineers shall be contacted regarding the proposed project and any required permits (i.e., 310, 404, Turbidity exemption, etc.). D. Effects on Wildlife and Wildlife Habitat. Because the subject site is largely surrounded by residential urban development, the site's potential to provide high quality wildlife habitat is negligible. This Preliminary Plat application was forwarded to the Montana Department of Fish, Wildlife and Parks for their review and comments. No comments have been received to date. Findings of Fact and Order Page 4 . . Allison Phase I Minor Subdivision Preliminary Plat E. Effects on the Public Health and Safety. Development in the floodplain on the subject property presents a possible threat to public health and safety. However, the five new proposed residential lots will not encroach into the floodplain. F. Compliance with Survey Requirements Provided for in Part 4 of the Montana Subdivision and Platting Act. The plat complies with the survey requirements. G. Compliance with Bozeman Area Subdivision Regulations . With conditions and requirements, the subdivision will comply with the Bozeman Area Subdivision Regulations. As with all Final Plats, a Platting Certificate must be submitted with the Final Plat. Two clothback (or an acceptable equivalent), two mylar and one digital copy of the Final Plat must be provided with the Final Plat application. H. Compliance with the Required Subdivision Review Procedures . The application complies with the subdivision review procedures. I. Provision of Easements for the Location and Installation of Any Planned Utilities. Currently, no utility easements are shown for the proposed lots. On the Final Plat, all existing utility and other easements must be shown on the plan. A public utility easement shall be provided along the side and rear lot lines of each lot. Rear and side yard utility easements shall be twenty (20) feet wide and centered on lot lines. In the event front yard easements are used, rear yard easements shall still be provided unless written confirmation is submitted to the planning department from all utility companies indicating that front yard easements.only are adequate. Front yard utility easements shall be twelve (12) feet wide. A drainage easement on the remainder tract must be provided for the proposed improved drainage pond. J. Provision of Legal and Physical Access to Each Parcel . All five of the proposed new residential lots will gain access from a new cul-de-sac which will be dedicated to the public. A one foot a "No Access" strip must be shown on the Final Plat to prevent direct access to proposed Lots 2 and 6 from Arnold Street. V. After considering all matters of record presented at the public hearing and meeting, the Commission found that the proposed preliminary plat for the Allison Phase I Minor Subdivision would comply with the requirements of the Bozeman Area Subdivision Regulations and the Montana Subdivision and Platting Act. The evidence, as stated or referenced in the Findings of Fact, justifies the conditions ordered herein for this subdivision to ensure that the final plat complies with all regulations; that the new lots are properly numbered; that proposed Lots 2 and 6 are of adequate width to accommodate a front yard setback and a corner sideyard setback; that the necessary permits are obtained from state and federal agencies; that direct access from proposed Lots 2 and 6 onto Arnold Street is prevented; that water, sewer and street infrastructure is properly designed and installed; that adequate water and sewer system capacity exists to service this development; that the environmental conditions on the site are addressed and are not detrimental to the health, safety and welfare of the public; that public trails are provided; and that noises emanating from the site during development shall not adversely impact adjoining properties.
