Technical assistance Cra-Lan Corporation P.O. Box 533 Bullhead City, AZ 86439 Paul J. Stokes & Associates 343 1 st Av. W . Kalispell, MT 59901 B. Location of Property: The site is located on the north side Sylvan Drive where it merges with College Avenue. The property is described as Assessor's Tracts 4CA and 2BA in Section 17, Township 28 North, Range 21 West, P.M.M., Flathead County, Montana. C. Size: Total area: 0.909 acres - Minimum lot area: 5,662 square feet, 0.132 acres Maximum lot area: 14,078 square feet, 0.323 acres D. Existing land use and zoning: Lot 1 is developed with a duplex, Lot 2 with a single family house, and lots 3 and 4 are vacant. The existing zoning on lots 1 and 2 is RA-1 Low Density Residential Apartment in the Kalispell Zoning Ordinance. The RA-1 district provides for multi -family housing and minimum lot size of 6,000 square feet and an additional 3,000 square feet for each additional unit beyond a duplex. The existing zoning on lots 3 and 4 is R-2 One Family Limited Residential in the Flathead County Zoning Regulations, which is proposed to be annexed and amended to city zoning. The planning board recommended that city R-3 zoning be adopted on lots 3 and 4. E. Adjacent Land Uses and Zoning: North: Single-family residential, County R-2 and City RA-1 zoning South: Single-family residential, Kalispell R-3 zoning East: Single family residential, County R-1 zoning West: Single family residential, Kalispell RA-1 zoning F. Availability of Utilities: City sewer and water, overhead power, and natural gas utilities are in place within the street right-of-way abutting the subdivision. Water: Sewer: Electricity: Telephone: Solid Waste: Fire: Schools: Police. City of Kalispell City of Kalispell Pacific Power Centurytel City of Kalispell City of Kalispell School District #5 City of Kalispell This application is reviewed as a minor subdivision in accordance with State statutory review criteria and the Kalispell Subdivision Regulations. 0 As noted above, RA-1 zoning currently exists on lots 1 and 2 and is proposed on lots 3 and 4. The subdivision would not comply with zoning in three respects. First, lot 1 would not meet the minimum lot size requirement of 6,000 square feet. The plat proposes a lot size of 5,662 square feet, which could become even less if additional street right-of-way dedication is required (see discussion below on streets). A duplex already exists on lot 1. Second, lot 1 would not meet the minimum lot width requirement of 60 feet. The plat proposes a lot width of 48 feet, which could become even less if additional right-of-way dedication is required. Third, the proposed lot boundary between lots 1 and 2 does not meet the 10-foot side yard setback requirement of the RA-1 district. One option for compliance would be to combine lots 1 and 2 into a single lot. Another option would be to obtain a variance from the board of adjustment for creating these three non- conforming circumstances. Staff recommends a condition requiring compliance with zoning, which would provide for either option. B. Conformance with the Master Plan The subdivision substantially complies with the Kalispell City County Master Plan. On the master plan map, this area is designated as both high density residential land and transition area to urban residential land. The site is along a boundary between more intensive and less intensive land use designations. In high density residential areas, the plan anticipates proximity to commercial area, public open space, and collector or arterial streets, and this site is the southern edge of a planned high -density residential area which accordingly abuts Conrad Dr., Woodland Park, and a neighborhood business district. An applicable master plan policy which would also support the subdivision is 8.a, to designate areas for development where urban services already exist or can be economically extended. C. Effects on Health and Safety: Flooding and soils: The Soil Survey maps an intermittent stream across the middle of the property, and the steep banks of this drainage channel are approximately eight feet high. The channel has been filled west of the site at College Av. and east of the site at Zimmerman Rd, so it no longer appears to function as a flowing drainage way for surface -water, but it does appear to function as a drainage retention area and potentially a wetland. At the public hearing on the Zone change, adjacent neighbors referred to this area as the slough and said that it typically has surface water and waterfowl in it each spring. Viewing the site in October, the channel had no surface water but did have some wetlands vegetation (horsetails) and several birch trees growing in it. The area is not mapped as 100- year or 500-year floodplain in FIRM panel 1810D, but the FIRM panel may be in error in this area, since the floodplain boundary is shown as a straight north/south line as if the floodplain mapping abruptly ended. The soils on the site are mapped in the Soil Survey as Swims silty clay loam (Sr), which are rated by the Natural Resources and Conservation Service as having severe limitations for building sites due to flooding and ponding. Engineer Paul Stokes representing the applicant has stated that, upon preliminary inspection, the site does not appear to qualify as a wetland protected under the Clean Water Act; and the intention of the owner is that most of the channel area on lot 4 would be filled to create a suitable building site. Subdivision regulations require the following: that the design and development of subdivisions contain suitable building sites which are properly related to topography and shall preserve the natural terrain, natural drainage, existing topsoil, trees, natural vegetation, and wildlife and fish habitats to the greatest extent feasible (3.02); and that a drainage easement be placed along a watercourse drainage way, channel, ditch, or stream, at a sufficient width to allow for maintenance and stream bank preservation (3.18.D). Such a drainage easement would keep building sites outside of this channel area and mitigate potential flooding and environmental impacts. With such an easement extending to the top of the bank, the building site area on lot 4 would be only 16 feet deep at the most; because the area between the bank and the front property boundary ranges from approximately 16-36 feet deep and the front setback requirement is 20 feet. To implement these subdivision requirements, staff recommends the following: a qualified engineer, hydrologist, or agency shall delineate any part of the site which qualifies as a wetland under the Clean Water Act, and such land shall be designated on the final plat as a drainage easement and shall not be used as a building site. If lot 4 does not contain a 40'x40' building site outside of such drainage easement and required zoning setbacks, then lots 3 and 4 shall be combined into one lot. Topography: The steep bank of the drainage channel across the site is approximately eight feet high and 100% slope. Subdivision regulations (3.06.E) require that each lot have a suitable building site (40' x 40' square pad) on existing undisturbed terrain of 30% or less slope. Lot 4 does not meet this requirement but a variance is considered below, since the slope is only 8 feet high, and a building site with a daylight basement or moderate fill appears feasible. Fire and emergency access- The site is in an urbanized area and would be served by the Kalispell Fire Department. The subdivision is approximately 0.8 miles from the fire station and police station. A hydrant is in place, which the Fire Chief commented is adequate to serve the subdivision. Access for fire and other emergency services is adequate. The site is in an urbanized area and is not mapped by the Montana Department of Fish, Wildlife and Parks as significant riparian or big game habitat. The channel/wetland area across the site may provide habitat for a variety of birds and other species. At the public hearing before the planning board on the zone change, neighbors commented that a variety of wildlife use this area. Retaining any qualified wetlands in the slough area as a natural drainage easement would mitigate potential impacts on wildlife (see further discussion above on flooding and soils). Channel/Wetland: As noted above, a natural drainage way crosses the site, which appears to function as a drainage retention area and potentially a wetland. At the public hearing on the zone change, adjacent neighbors referred to this area as the slough and said that it typically has surface water and waterfowl in it each spring. Engineer Paul Stokes representing the applicant has stated that, upon preliminary inspection, the site does not appear to qualify as a wetland protected under the Clean Water Act; and the intention of the owner is that most of the channel area on lot 4 would be filled to create a suitable building site. Based on subdivision requirements to conserve natural drainages within drainage easements, staff recommends that a qualified professional shall delineate any part of the site which qualifies as a wetland under the Clean Water Act, and such land shall be designated on the final plat as a drainage easement. See further discussion above on flooding and soils. 4 Other effects: The building site portion of the site is relatively flat, requiring minimal grading except for lot 4 on which a variance from slope standards is discussed below. The road is paved, preventing potential road dust impacts on air quality. F. Effects on Local Services: Annexation: Annexation to the city would improve the overall level of public services to the subdivision, including municipal utilities, a staffed fire department, substantially more police staffing per capita and size of service area, and more extensive street infrastructure. Water and sewer: Municipal water and sewer lines are already in place in the street right-of-way abutting each lot. Streets: The subdivision would provide for 7-12 dwelling units, depending on the zoning approved on lots 3 and 4. The Institute of Transportation Engineers estimates average daily traffic for a single-family house at 10 daily trips and for a low-rise apartment unit at 6.6 daily trips, or 53-79 daily trips with full buildout of the subdivision. College Av. and Sylvan Dr. abutting the site are city streets with approximately 22-foot paved width and street lights but no curbs, gutters, sidewalks, or street trees. At the public hearing before the planning board on the zone change, neighbors commented that the two corners abutting the site form an S-curve which is a significant traffic hazard. Kalispell subdivision regulations require minimum road width of 28 feet and installation of curb, gutter, and sidewalk on the subdivision side of the street, but also provide that city council can require waiver of protest to an SID in lieu of street improvements where minor subdivisions front on existing streets. The public works director and planning staff recommend completion of the street improvements in this case, due to the additional traffic impact of multi -family housing and that street improvements would significantly enhance the corner of College Av. and Sylvan Dr. which neighbors have objected is unsafe. Subdivision regulations also require minimum right-of-way width of 60 feet and that utilities be placed within right-of-way/easement at least 20 feet wide unless specified otherwise by the utility company. A portion of College Av. has right-of- way only 40 feet wide and the existing power line is outside the right-of-way, approximately six feet into the site. Although extending right-of-way width 20 feet on the other side of the street would better match the 60-foot right-of-way on the curve of Sylvan Dr., such dedication would burden that neighboring lot owner to the south by placing the right-of-way only 13 feet from the house there, and such right-of-way configuration would not be consistent with the existing location of the pavement and power line. Tim Hunt at Pacific Power commented that extending the right-of-way north to include the power line and an additional two -foot beyond that point would be adequate for utility maintenance in this case. Accordingly, the Public Works Director recommends that additional College Av./Sylvan Dr. right-of-way be dedicated from the subdivision to include and extend two feet beyond the power line from the corner to the east end of the subdivision's Sylvan Dr. street frontage. East of this point, subdivision regulations would require dedication of additional easement to accommodate utilities in accordance with plans approved by the applicable utility companies. Schools: Staff estimates that 5-6 additional school -age children would reside at the site with full build -out of the subdivision. The property is located within the Kalispell School District. Gary Rose of the district commented that the subdivision would not have a significant effect on schools. Parks: Subdivision regulations do not require parkland dedication for minor subdivisions. The site is within walking distance, approximately 1,100 feet, of Woodland Park. Police Protection: The site would be served by the Kalispell Police Department. The subdivision is approximately 0.8 miles from the police station. Fire Protection: The site would be served by the Kalispell Fire Department. The subdivision is approximately 0.8 miles from the fire station. A hydrant is in place, which the Fire Chief commented is adequate to serve the subdivision. Refuse Disposal: Refuse disposal would be provided by the City of Kalispell. The County Landfill has adequate capacity to accommodate the additional refuse generated from this subdivision. Medical -Services: Medical services are available at Kalispell Regional Hospital approximately 2.5 road miles from the site. G. Effects on Agriculture and Agricultural Water User Facilities: The 0.9-acre site is in urbanized area abutting the city. No significant impact on agriculture or water user facilities is anticipated. H. Compliance with the Flathead County Subdivision Regulations: The proposal complies with subdivision requirements, subject to meeting conditions that address improvements and design, except that a variance would be required from slope standards for lot 4. Subdivision regulations (3.06.E) require that each lot have a suitable building site (40' x 40' square pad) on existing undisturbed terrain of 30% or less slope. Lot 4 does not meet this requirement. Subdivision regulations provide for granting of variances subject to adoption of findings that the following criteria are met, each of which is discussed below. 1. The granting of the variance will not be detrimental to public health, safety, or general welfare or injurious to other adjoining properties. The steep bank of the drainage channel across the site is approximately eight feet high and 100% slope. It crosses the middle of lot 4. The slope standard addresses potential impacts of steep slope development from slope instability, erosion and siltation, reduced ability to suppress fires on steeper slopes, and hillside scarring. The slope standard is intended to address larger, continuous steep slopes although the standard does not specify a minimum height. Since the slope is only 8 feet high, a building site with a daylight basement or placed on suitable fill appears feasible without undue impacts on slope stability, erosion, fire safety, or scarring. Staff recommends that a professional engineer certify that the slope poses no significant geological hazard for the development of lot 4 or for neighboring properties, and that any recommendations for mitigation be noted on the final plat. 2. The conditions on which the variance is based are unique to the property on which the variance is sought and are not applicable generally to other property. The condition on which the variance is based is that the slope is only 8 feet high, which is unique to the property and not applicable generally to other property. 3. Because of the particular physical surroundings, shape or topographical conditions of the specific property, a particular hardship would result as distinguished by a mere inconvenience if the strict letter of the regulations is enforced. The physical condition on which the variance is based is that the slope is only 8 feet high. The particular hardship is that lot 4 would not be developable if the standard is applied. 4. The variance will not cause a substantial increase in public costs. Substantial increases in public costs as a result of the variance are not apparent. 5. The variance will not, in any manner, vary the provisions of any adopted zoning regulations or master plan. The variance would not be contrary to specific provisions of the zoning and master plan. Staff recommends approval of the variance from 3.06.E for lot 4, subject to the condition that a professional engineer certify that the slope poses no significant geological hazard for the development of lot 4 or for neighboring properties, and that any recommendations for mitigation be noted on the final plat. The Flathead Regional Development Office would recommend that Kalispell City Council adopt the Staff Report #KSR 98-3 as findings of fact and grant preliminary plat approval for this subdivision subject to the following conditions: The subdivision shall comply with the Kalispell Zoning Ordinance. Either combine lots 1 and 2 into a single lot, or obtain zoning variances for lot width on lot 1, lot size on lot 2, and the side yard setback on lot 2. 2. The subdivision shall comply with the Kalispell Design and Construction Standards, as approved by the Public Works Department. a) Install street improvements including curb, gutter, and detached sidewalk on one side where the subdivision abuts the street. b) Dedicate additional College Av./Sylvan Dr. right-of-way from the subdivision to include and extend two feet north of the power line from the street intersection to the east end of the subdivision's Sylvan Dr. street frontage. c) Prepare and implement an engineered drainage plan. d) Sewer and water facilities shall meet design and improvements standards. 3. A variance is granted from 3.06.E for lot 4, subject to the conditions that a professional engineer certify that the slope poses no significant geological hazard for the development of lot 4 or for neighboring properties, and that any recommendations for mitigation be noted on the final plat. 4. A qualified engineer, hydrologist, or agency shall delineate any part of the site which qualifies as a wetland under the Clean Water Act, and such land shall be designated on the final plat as a drainage easement in accordance with Section 3.18.D of the Kalispell Subdivision Regulations and shall not be used as a building site. If lot 4 does not contain a 40'x40' building site outside of such drainage easement and required zoning setbacks, then lots 3 and 4 shall be combined into one lot. 5. Dedicate utility easement to accommodate the existing utilities east of the subdivision's Sylvan Dr. street frontage in accordance with plans approved by the applicable utility companies. 6. Install street trees on one side of the subdivision street frontage in accordance with a plan approved by the Kalispell Parks Department. 7. Obtain approach permits from the Public Works Department for driveway approaches onto College Av. and Sylvan Dr. The requirements of the permit shall be met prior to final plat approval. 8. The following notes shall be placed on the final plat: a. All house numbers shall be placed to be visible from the road, either at the driveway entrance or on the building. b. New utilities shall be installed underground. 9. The preliminary plat shall be valid for a period of three years from the date of approval.
