City Council! OA 04-06 December 20, 2004 Page 2 to the 2 '/z- acre zoning area. Although the zoning will allow 2 '/z-acre lots, there will still be a number of parcels that are 5 plus acres in size. These are the parcels that are being considered for an increased accessory structure size. The second condition is that there is an ever increasing usage on these larger parcels of land for hobby farms and home occupations. Allowing larger accessory structures will allow the city to require conditions to have these activities be placed inside a structure. For example, a contracting busine~s could have conditions placed on it that all equipment shall be stored inside the building, which now might be difficult with the limited accessory building sizes. The third condition is the increasing level of extra vehicles, equipment and "toys" property owners have. Many property owners that live on larger lots have items such as boats, snowmobiles, A TV's, RV's and the equipment need to transport these items. Staff receives many inquiries on why larger outbuildings cannot be built, as citizens want to store their extra belongings under cover. Providing an increased allowed square footage would allow these items to be stored indoors and out of sight. ut Coverage Calculations Staff assembled a chart showing the cw:rent percentage of lot coverage with the current maximum allowed accessory structure sizes. It was found that the average percentage for lot coverage for the 2 '/z-acre, Category C (which much of the city will eventually be zoned) was 2.1%. Staff then computed the square footages based on the lot coverage percentages of 1.5% and 2.0%. The 1.5% was chosen as it was the average between the high end acreage of Category C and the low end acreage of Category D. Again, the 2% was used as it is the average of the current 2 '/z-acre, Category C. After analyzing the numbers, it was decided that the average of the two percentages, or 1. 75%, should be used to determine the increased square footages of accessory structures for lots 5-acres or larger. Staff used 1.75% of the smallest lot size of each category and then rounded up to the nearest thousand. These are the proposed accessory structure sizes to be allowed: 5 to 10 acres 10 to 20 acres 20 to 39 acres 40 plus acres 4,000 sqft 8,000 sqft 16,000 sqft max of 2% of the lot area Even though there are significant increases in the proposed sizes for lots 10-acres or larger, the percentage of lot coverage is no where near those that are allowed on smaller lots. A quarter-acre lot can have 18% of the lot covered with accessory structures, while the proposal is to allow 1. 7 5% lot coverage on lots 5-acres or larger. The increased square footages will not create an adverse impact due to total lot coverage. The number of accessory structures shall not apply to parcels that are 40-acres of larger. This has not changed as farmsteads typically require more than two detached accessory structures (barns, silos, storage sheds, etc.) S:\PLANNING\Case FiJes\2004\OA 04-06 Access StruccAgAnimals\OA 04-06_CC.doc
