regardless of zoning and with no guarantees that the agricultural <br />operation will not be converted to residential in the near future. <br />Also, new developments in or near agricultural areas are required <br />to prohibit caribbean fruit fly host plants. Conversely, new <br />agricultural research facilities are required to provide special <br />setbacks or buffers between structures and test plots and adjacent <br />residential property. <br />•F rent of Au - u t a w eeddential Interface <br />To determine the extent that active agricultural uses abut vacant <br />tracts having residential development potential and located within <br />the urban service area, staff reviewed aerial photographs of the <br />county. Based on that review, staff has developed a map depicting <br />active agricultural areas within the urban service area (attachment <br />W. Based on that map, staff determined that the interface between <br />agricultural and residential uses in the county is quite extensive. <br />Although active agriculture exists throughout the Urban Service <br />Area, it is most prevalent in the following areas (some of which <br />are among the fastest developing areas of the county): <br />1. The north side of CR 510, between 66th Avenue and 90th Avenue; <br />2. East of US 1, from The Main Relief Canal to the Brevard County <br />Line; <br />3. South of SR 60, between 43rd Avenue and 58th Avenue <br />4. Within the SR 60 Corridor; <br />5. The east side of 66th Avenue, between 26th Street and 49th <br />Street; <br />6. The southwest section of the urban service area near Oslo Road <br />and 82nd Avenue; and <br />7. The barrier island, north of the Town of Orchid. <br />*o=rison with Other Counties <br />As part of its analysis, staff surveyed three Florida counties that <br />are similar to Indian River County to determine their setback and <br />buffer requirements where agricultural and residential uses abut. <br />The table below compares those three counties with each other and <br />with Indian River County. <br />COMPARISONS OF SETBACKS/BUFFERS WSERE <br />AGRICULTURE AND RESIDENTIAL ABUT <br />COUNTY <br />ARE SPECIAL <br />SETBACKS/BUFFERS <br />WHICH LAND USE <br />PROVIDES THE <br />DESCRIPTION OF SPECIAL <br />SETBACKS/SUFFERS <br />REQUIRED? <br />SETBACKS/BUFFERS <br />MARTIN <br />YES <br />RESIDENTIAL <br />40' WIDE LANDSCAPED STRIP WITH <br />6' HIGH OPAQUE FENCE, WALL OR <br />BERM. <br />ST. <br />NO <br />NOT APPLICABLE <br />NOT APPLICABLE <br />LUCIE <br />CITRUS <br />YES <br />AGRICULTURE <br />20' TO 50' WIDE LANDSCAPED <br />STRIP; DEPTH DEPENDS ON <br />DENSITY OF PLANTINGS <br />INDIAN <br />YES <br />RESIDENTIAL <br />50' SETBACK OR 25' LANDSCAPED <br />RIVER <br />STRIP (TYPE B) WITH A 6' HIGH <br />OPAQUE FEATURE <br />As noted in the above table, only St. Lucie County does not require <br />special treatment of the residential/agricultural border. In the <br />other counties, the special buffer widths range from 20 feet to 50 <br />feet wide and usually require plantings and/or an opaque feature. <br />Citrus county was the only one of the four counties surveyed <br />(including Indian River County) that requires the agricultural use, <br />rather than the residential use, to provide the buffer. <br />In terms of setback width and buffer requirements, Indian River <br />County's current regulations appear to be more stringent than those <br />in St. Lucie and Citrus Counties, but less stringent than Martin <br />County's. <br />MAY 20, 1997 <br />19 <br />BQO!; 101 PAGE 48 <br />
