TO: The honorable Members DATE: September 16, 198FILE: of the Board of County Commissioners DIVISION HEAD CONCURRENCE: r SUBJECT: ZONING ORDINANCE Robert M. Keatig, A AMENDMENT CONCERNING Planning & DE lopmer16 Director MINIMUM DWELLING UNIT SIZE IN RS -3 ZONING �S DISTRICT. Richard Shearer, _FROM: Chief, Long -Range Plann#V'uFERENCES:zoning Ord. Memo It is requested that the data herein presented be given formal consideration by the Board of County Commissioners at their regular meeting of September 30, 1986. DESCRIPTION & CONDITIONS Subsequent to the County rezoning all of the unincorporated areas of the County in conformance with the Comprehensive Plan, several problems have arisen in developing lots -of -record which have an LD -1 land use designation (allowing up to 3 units/acre) and which are now zoned RS -3, Single -Family Residential District (upr to 3 units/acre). Many of these lots were platted under the old R-1, Single -Family District (up to 6 units/acre), regulations and some RS -3 zoned lots were platted prior to the County having a zoning ordinance. Many of these lots cannot meet the minimum size or dimension criteria of the RS -3 district so are nonconforming lots -of -record. The main problems are that the new RS -3 district requires a minimum dwelling unit size of 1200 square feet and a. minimum side yard setback of 15 feet. The old R-1 zoning district had a minimum dwelling unit size of 750 square feet and a minimum side yard setback of 10 feet. Moreover, the RS -3 district has a minimum lot width of 80 feet while the old R-1 district had a minimum lot width of 70 feet and several of the nonconforming lots -of -record in the RS -3 district were platted before the County had a zoning ordinance and are only 60 feet wide. Property owners have complained about 15 foot side yard setbacks on 60 foot wide lots which limit the width of houses to 30 feet. However, the largest problem has been in Vero Lake Estates where property owners are complaining about having to construct 1200 square foot houses on $2,500 lots. On August 28, 1986, the Planning and Zoning Commission voted 5 -to -0 to recommend approval of this request. ALTERNATIVES & ANALYSIS The planning staff feels that the RS -3 regulations are creating unnecessary hardships for many property owners who have nonconforming lots -of -record which were not designed to meet the RS -3 minimum requirements. While the staff feels that the RS -3 regulations are appropriate for the majority of the land designated as LD -1 on the Comprehensive Plan and that the RS -3 regulations should be applied to future subdivisions, some relief is necessary for the nonconforming lots -of -record which cannot meet the new RS -3 requirements. In order to grant some relief without damaging the integrity of the RS -3 district, staff -has prepared a proposed amendment to the RS -3 district which would allow nonconforming lots -of -record which are 70 feet or less in width to have their minimum side yard setback reduced to 10 feet. The proposed amendment would also reduce the minimum dwelling unit size for nonconforming lots -of -record to 900 square feet. 59 SEP 30 M6 aOu.. a F k,,; .. 894
